Description

Technical Field

[0001] This invention relates to a reaction apparatus. Background Technology

[0002] Reaction apparatuses exist for producing desired products from powdery or granular materials by providing them with a specific atmosphere. For example, a reaction apparatus, often called a rotary kiln, heats a hollow reaction vessel rotating around a central axis. The desired product is produced by tumbling the material while it passes through this reaction vessel. Another example is a roller hearth kiln, which produces the desired product by passing the material and the workpiece through a tunnel-type reaction vessel. Various other reaction apparatuses have also been developed.

[0003] For example, Patent Document 1 discloses the following reaction apparatus. The reaction apparatus includes a screw feeder body serving as a pressure reaction vessel, a catalyst supply section for introducing a catalyst into the screw feeder body, and a low-hydrogen supply section for introducing low-grade hydrocarbons into the screw feeder body. The reaction apparatus includes a screw for conveying the generated nano-carbon, a solid discharge section for discharging the catalyst and nano-carbon conveyed by the screw, and a gas discharge section for discharging the generated hydrogen gas to the outside of the feeder body.

[0054] The invention will be described below through embodiments thereof. However, the invention, as claimed, is not limited to the following embodiments. Not all components described in the embodiments are necessary means to solve the problem. For clarity, the following description and drawings are appropriately omitted or simplified. In the drawings, the same reference numerals are given to the same elements, and repeated descriptions are omitted where appropriate.

[0055] <Reference Example 1>

[0056] refer to Figure 1 The main components of the reaction apparatus according to Reference Example 1 will be explained. Figure 1 This is a side view of the reaction apparatus 10 based on Reference Example 1. Figure 1 The reaction apparatus 10 is shown in a partially cut-open state for easier understanding.

[0057] The reaction apparatus 10 is, for example, an apparatus for producing a product by applying conditions, such as predetermined physical stimuli, to a powdery or granular material to be processed. The reaction apparatus 10 includes a cylindrical reaction vessel 100 (reactor), a supply section (supply port 101) for supplying the material to be processed R10 to the reaction vessel 100, a discharge section (discharge port 102) for discharging the product from the reaction vessel 100, a conveying mechanism 120 (e.g., a screw) for conveying the material to be processed R10 supplied to the reaction vessel 100 from the supply section to the discharge section, a fluid supply section (first fluid inlet 131, first fluid outlet 132, first valve 134, etc.) for supplying fluid in contact with the conveyed material to the reaction vessel 100, and a temperature control section (temperature control zone 110, etc.) that controls the temperature along the long axis AX of the reaction vessel 100. 100 Temperature control of the reaction vessel 100 is performed in each region of different areas in the direction of reaction.

[0058] There are no particular restrictions on physical stimuli, as long as they are means used in the process of transforming the substance to be treated into the product. Examples of physical stimuli include temperature changes, such as heating and cooling. Examples of physical stimuli include stress transfer, such as stirring, mixing, kneading, and pulverizing. Physical stimuli are, for example, reactions that accept electrons or free radicals.

[0059] In the reaction apparatus 10, the material to be processed R10, supplied to the reaction vessel 100, is heated while being conveyed by the conveying mechanism 120 to the outlet of the reaction vessel 100, and a predetermined fluid in contact with the conveyed material to be processed R10 is supplied to the interior of the reaction vessel 100, thereby continuously processing the material to be processed R10 at a predetermined temperature. The material to be processed can be a solid, a fluid, or a mixture thereof. In order to enable the material to be processed to be stirred, for example, while being conveyed, the reaction vessel 100 itself can be rotatable, or the conveying mechanism 120 having a rotatable structure can be provided in the reaction vessel 100.

[0060] While there are no particular restrictions on the type or state of the substance and product, the substance and product can be inorganic substances containing lithium as a component, such as metal oxides or metal sulfides, or they can be organic substances, such as hydrocarbons or food products. The substance can be a solid, such as a powder or granular material, or it can be a fluid, such as a liquid or gas.

[0061] In the process of conversion into a product, the substance to be treated can be converted into a product via an intermediate. The form or state of the intermediate is not particularly limited. When two or more reactions are carried out in a stepwise manner, the intermediate can be, for example, a product from each reaction. In this case, the intermediate is, for example, an anhydrous compound generated by heating a hydrated compound. Alternatively, the intermediate can be a monosaccharide generated by hydrolyzing a polysaccharide. The intermediate can be a calcined body of at least a portion of the substance to be treated, formed by grain growth or calcination. The intermediate can be in a state where at least a portion of the substance to be treated is liquefied or vaporized. The intermediate can be in a state where the temperature, hardness, etc., of the substance to be treated has changed, even if its appearance has not changed. The intermediate can be in a form or state different from those described above.

[0062] There are no particular restrictions on the type or state of the products, and the products can be solids, such as powders or granules, or fluids, such as liquids or gases. Alternatively, the products can be mixtures containing materials different from the material to be treated, such as catalysts or transport aids. The products can be mixtures containing two or more compounds, such as a main product and a byproduct.

[0063] While there are no particular limitations on the shape and size of the material to be treated and the product, when both the material to be treated and the product are granular materials, their particle size is preferably 50 mm or less, more preferably 0.005-20 mm. When the material to be treated and the product have a blocky shape, the ratio of their diagonal lengths (aspect ratio) is preferably 1-10, more preferably 1.3-1.8.

[0064] The reaction apparatus 10 includes a reaction vessel 100, a temperature control zone 110, a conveying mechanism 120, a first fluid control zone 130, and a second fluid control zone 140 as its main components.

[0065] The reaction vessel 100 has, for example, a cylindrical shape and includes a supply port 101 for receiving the material to be processed and a discharge port 102 for discharging the product. The supply port 101 is an example of the supply section of this disclosure. Note that the shape and construction of the reaction vessel 100 are not particularly limited. The cross-sectional shape of the reaction vessel 100 may be, for example, circular or elliptical, or polygonal, such as quadrilateral, or other shapes. For example, the reaction vessel 100 may be formed by a single component, or two or more components may be connected to each other. When two or more components are connected to each other, fastening means, such as bolts, may be used at the points where these components are connected.

[0066] The reaction vessel 100 includes an intermediate section A3 between a supply port 101 and an outlet port 102. There are no particular limitations on the number of supply ports 101, the number of outlet ports 102, and the number and arrangement of the intermediate section A3. For example, two or more supply ports 101 and two or more outlet ports 102 may be respectively located at both ends of the intermediate section A3.

[0067] The supply port 101 may alternatively be located in the middle of the reaction vessel 100, and each of the two corresponding ends of the supply port 101 has a middle portion A3 and a discharge port 102. In this case, the material to be processed R10 can be supplied to the middle of the reaction vessel 100, and the product R11 can be discharged from one end side and the other end side of the reaction vessel 100. Furthermore, in this case, a screw can be used as a conveying mechanism 120, and the orientation of the spiral-shaped protrusion in the screw (screw orientation) can be reversed, for example, before and after the supply port 101 (with the supply port 101 as the boundary), thereby causing the material to be processed R10 to be branched and conveyed to one end side and the other end side of the reaction vessel 100, respectively, with the supply port 101 as the boundary. On the other hand, when the outlet 102 is located in the middle of the reaction vessel 100 and the middle portion A3 and the supply port 101 are provided at two corresponding ends of the outlet 102, a screw can be used as the conveying mechanism 120, for example. The orientation of the spiral-shaped protrusion in the screw (spiral orientation) can be reversed, for example, before and after the outlet 102 (with the outlet 102 as the boundary). This allows the product R11 to be conveyed in such a way that it is collected from one end of the reaction vessel 100 to the other end, with the outlet 102 as the boundary. In this way, for example, when multiple reaction devices 10 are connected in parallel, the means for conveying the product R10, product R11, etc., in a branching or collecting manner is preferred.

[0068] The reaction vessel 100 is formed of a material that allows for temperature changes during the production of products in the furnace and allows contact with the material supplied to the furnace (the substance to be processed, etc.) or the material to be produced (the product, etc.). The reaction vessel 100 and the conveying mechanism 120 may be formed, for example, of an alloy, ceramic, carbon, or a composite material containing two or more of the above. An alloy is a metallic material containing at least one alloying element selected from nickel, cobalt, chromium, molybdenum, tungsten, tantalum, titanium, iron, copper, aluminum, silicon, boron, carbon, etc. In addition to ceramic materials containing oxides (such as alumina or zirconium oxide), carbides (such as silicon carbide or titanium carbide), nitrides (such as silicon nitride or titanium nitride), or borides (such as chromium boride), ceramics may contain glass materials, at least a portion of which has an amorphous structure. Carbon is a carbon material, such as crystalline graphite or fiber-reinforced graphite.

[0069] Figure 1The reaction apparatus 10 shown is horizontally oriented and includes... Figure 1 The upper left end of the supply port 101 and in Figure 1 The lower right outlet 102. Figure 1 The reaction vessel 100 shown receives the material to be processed R10 from the supply port 101. The reaction apparatus 10, via a conveying mechanism 120 provided within the reaction vessel 100, transports the material to be processed R10 received from the supply port 101 (A1) of the reaction vessel 100 through an intermediate section A3 to the discharge port 102 (A2) of the reaction vessel 100. By passing the material to be processed R10 through the intermediate section A3 of the reaction vessel 100, the reaction apparatus 10 produces product R11 from the material to be processed R10. Then, the reaction vessel 100 discharges the produced product R11 from the discharge port 102.

[0070] Temperature control zone 110 includes a temperature control device, i.e., a heating device or a cooling device, and controls the temperature of the reaction vessel at a predetermined position in the intermediate portion A3 between the supply port 101 and the outlet port 102. Temperature control zone 110 and the like are examples of the temperature control units of this disclosure. Figure 1 The temperature control zone 110 shown includes a heating device at the middle portion A3 of the reaction vessel 100, which surrounds the cylindrical reaction vessel 100. Examples of the heating device include any temperature-controllable heater, such as a sheath heater, coil heater, or ceramic heater. The heating device performs heating, for example, in a range from ambient temperature to approximately 1000 degrees Celsius. The temperature control zone 110 may be configured such that it surrounds the cylindrical reaction vessel 100 in the middle portion A3 of the reaction vessel 100 in a separate manner by means of multiple heating devices. Therefore, different temperatures can be set for different parts around the reaction vessel 100, both vertically and horizontally. Furthermore, the temperature of the middle portion A3 can be further controlled for each region in different regions along the minor axis of the reaction vessel 100. For each region of the middle portion A3 of the reaction vessel 100, the temperature control zone 110 may also be configured along the axis AX of the conveying mechanism 120. 120 Different temperatures are set for different directions, which will be explained later. Temperature control zone 110 can, for example, control the temperature variation applied to the workpiece R10 in the first fluid control zone 130 and the second fluid control zone 140, which will be explained later.

[0071] The temperature control zone 110 may also include control devices for controlling the heating or cooling devices. The temperature control zone 110 may, for example, include a thermometer for monitoring the temperature at a predetermined location within the reaction vessel 100. Where the heating device operates on the principle of heating via electric current, the reaction vessel 100 can be temperature-controlled by monitoring the current value.

[0072] The temperature control zone 110 may have a structure that enables heating or cooling via circulating water, oil, etc. The temperature control zone 110 may also have a structure that enables cooling via a Peltier element, etc. With the above-described structure, the temperature control zone 110 can move along the axis AX of the conveying mechanism 120 within the reaction vessel 100. 120 The direction is set to determine various temperature distributions.

[0073] As described above, the temperature control zone 110 can be located along the long axis AX of the reaction vessel 100. 100 The temperature of the reaction vessel 100 (e.g., the middle section A3) is controlled in the direction of the reaction vessel 100 in different regions.

[0074] The conveying mechanism 120 extends, for example, from one end A1 to the other end A2 of the reaction vessel 100, thereby conveying the material to be processed R10 supplied from the supply port 101 to the discharge port 102. The shape and conveying method of the conveying mechanism 120 according to this disclosure are not limited, as long as the conveying mechanism 120 is capable of conveying raw materials, products, etc. The conveying mechanism 120 may be a spiral provided in the reaction vessel 100 extending from one end to the other. The conveying mechanism 120 may be a drum provided in the reaction vessel 100 extending from one end to the other. The conveying mechanism 120 may be a belt conveyor provided in the reaction vessel 100 extending from one end to the other. The conveying mechanism 120 may be an air supply device provided in the reaction vessel 100. The conveying mechanism 120 may be a vibration generating device provided in the reaction vessel 100. The conveying mechanism 120 may be a device different from the above-described devices.

[0075] The size of the conveying mechanism 120 is not particularly limited, and may, for example, be shorter than the entire length of the reaction vessel 100. While the material used to form the conveying mechanism 120 is not particularly limited, similar to the reaction vessel 100, it is desirable to form the conveying mechanism 120 from a material that allows for temperature changes during product manufacturing and allows contact with the substance supplied to the vessel (the material to be processed, etc.) or the substance to be manufactured (the product, etc.). The conveying mechanism may, for example, be formed from alloys, ceramics, carbon, or composite materials containing two or more of the above.

[0076] Figure 1 The conveying mechanism 120 shown is, for example, a helix, and a helical protrusion 121 is formed around the main shaft extending along the long axis of the reaction vessel 100. As the protrusion 121 rotates while in contact with the workpiece R10, the conveying mechanism 120 transports the workpiece R10 from the supply port side to the discharge port side.

[0077] Figure 1The shape of the protrusion 121 shown is merely an example, and its shape is not limited to this. The protrusion 121 may have different shapes for different regions within the reaction vessel 100. More specifically, for example, the pitch of the helix of the protrusion 121 may be varied. The helical shape of the protrusion 121 need not be a single helix, and may be a double helix or more. The protrusion 121 may include portions that do not have a helical shape. Furthermore, the protrusion 121 may be positioned at a 90-degree angle relative to the long axis of the helix at its apex. The protrusion 121 may also extend at a 0-degree angle relative to the long axis of the helix. Therefore, the reaction apparatus 10 can set the movement speed, movement behavior, etc., of objects present in the reaction vessel 100 for corresponding regions. More specifically, for example, the reaction apparatus 10 conveys, stirs, mixes, retains, kneads, or crushes objects in the reaction vessel 100.

[0078] The conveying mechanism 120 is pivotally supported at both ends of the reaction vessel 100 (one end A1, the other end A2). Additionally, Figure 1 The conveying mechanism 120 shown is a helical mechanism connected (linked) to the drive unit 150 at one end B1 of the reaction vessel 100. The drive unit 150 is an example of a drive device for the conveying mechanism 120 according to this disclosure. The drive unit 150 includes a motor 151 disposed at one end of the reaction vessel 100 and a reducer 152 disposed between the motor 151 and one end A1 of the reaction vessel 100. The reducer 152 includes an input shaft connected to the rotating shaft of the motor 151 and an output shaft connected to one end B1 of the conveying mechanism 120, causing the conveying mechanism 120 to rotate by reducing the rotation of the rotating shaft of the motor 151 and transmitting it to the conveying mechanism 120. Note that the drive unit 150 may be configured to change the rotational speed of the conveying mechanism 120. In this case, the drive unit 150 may be a variable-speed motor, or it may be a device obtained by combining a motor with a constant speed and a reducer with a variable reduction ratio.

[0079] The first fluid control region 130 includes a first fluid inlet 131 and a first fluid outlet 132 to allow first fluid to pass through the reaction vessel 100 in a predetermined area within the intermediate portion A3. The first fluid control region 130 is disposed within the reaction vessel 100 between the supply port 101 and the second fluid control region 140. The first fluid inlet 131 is connected to a first fluid supply pipe 133 and supplies the first fluid from the first fluid supply pipe 133 to the reaction vessel 100. The first fluid supply pipe 133 includes a first valve 134 for regulating the flow rate of the first fluid. Furthermore, the first fluid supply pipe 133 can intermittently supply the first fluid to the reaction vessel 100 by opening or closing the first valve 134, while controlling the time. The first fluid outlet 132, connected to a first fluid discharge pipe 135, is an orifice for discharging fluid from the first fluid control region 130 to the outside of the reaction vessel 100. The first fluid discharge pipe 135 may include a valve or discharge mechanism for regulating the flow rate or velocity of the fluid to be discharged from the reaction vessel 100. The discharge mechanism is, for example, a suction mechanism using the Venturi effect, such as a pump or ejector. In another example, multiple first fluid inlets 131 and multiple first fluid outlets 132 may be provided. The location of the first fluid inlets 131 and first fluid outlets 132 within the first fluid control region 130 is not particularly limited; they may be located at the top, bottom, or side of the reaction vessel 100. The first fluid inlets 131 may be located at the bottom of the reaction vessel 100, and the first fluid outlets 132 may be located at the top of the reaction vessel 100, thereby generating a gas flow in a predetermined direction within the reaction vessel. With this configuration, the first fluid can easily come into contact with the substance to be treated, thus allowing the substance to react appropriately. The inner diameter of the first fluid inlet 131 may be made smaller than the inner diameter of the first fluid supply pipe 133, such that the first fluid vaporizes when supplied to the reaction vessel 100. With this configuration, the temperature of the atmosphere surrounding the substance to be treated can be regulated by the heat of vaporization, thus allowing for appropriate control of the reaction of the substance to be treated.

[0080] With the above configuration, in the first fluid control zone 130, the reaction device 10 transforms the material to be processed R10 into an intermediate by contacting it with the first fluid. Furthermore, the reaction device 10 discharges the fluid after contact with the material to be processed R10 to the outside of the first fluid control zone 130. Additionally, in the reaction device 10, the conveying mechanism 120 rotates to convey the material to be processed R10 or the intermediate, thereby also contacting it with the first fluid, thus promoting the reaction induced by the first fluid. The form and composition of the first fluid are not limited, as long as the first fluid is fluid. The first fluid can be a gas or a liquid. The first fluid can be a dispersion of solids in a liquid. Furthermore, by supplying the first fluid to the reaction device 10, the temperature of the reaction vessel 100 and the temperature of the conveying mechanism 120 can be partially controlled. Therefore, the reaction device 10 can efficiently control the temperature of the material to be processed R10 and efficiently transform the material to be processed R10 into an intermediate. A mechanism for adjusting the temperature and pressure of the first fluid can be provided before supplying the first fluid to the reaction vessel 100.

[0081] The second fluid control region 140 includes a second fluid inlet 141 and a second fluid outlet 142 for allowing a second fluid to pass through in a region different from the first fluid control region 130 in the intermediate portion A3. That is, in a region different from the first fluid control region 130, the second fluid control region 140 may have a structure equivalent to that of the first fluid control region 130.

[0082] A second fluid control zone 140 is disposed within the reaction vessel 100 between the first fluid control zone 130 and the outlet 102. A second fluid inlet 141 is connected to a second fluid supply pipe 143 and supplies second fluid from the second fluid supply pipe 143 to the reaction vessel 100. The second fluid supply pipe 143 includes a second valve 144 for regulating the flow rate of the second fluid. Furthermore, the second fluid supply pipe 143 can supply the second fluid to the reaction vessel 100 by opening or closing the second valve 144, thereby controlling the timing of the supply of the second fluid to the reaction vessel 100 to be intermittent. A second fluid outlet 142, connected to a second fluid discharge pipe 145, is an orifice for discharging fluid from the second fluid control zone 140 to the outside of the reaction vessel 100. The second fluid discharge pipe 145 may include a valve or discharge mechanism for regulating the flow rate or velocity of the fluid discharged from the reaction vessel 100. The discharge mechanism is a suction mechanism, such as a pump or ejector. The first fluid inlet 131, the first fluid outlet 132, and the first valve 134 are examples of the fluid supply section of this disclosure.

[0083] With the above configuration, in the second fluid control region 140, the reaction apparatus 10 generates product R11 by contacting the intermediate material after passing through the first fluid control region 130 with the second fluid. Furthermore, the reaction apparatus 10 discharges the fluid after contact with the intermediate material to the outside of the second fluid control region 140. The form and composition of the second fluid are not limited, as long as the second fluid is fluid. The second fluid can be a gas or a liquid. The second fluid can be a dispersion of a solid in a liquid. By supplying the second fluid to the reaction apparatus 10, the temperature of the reaction vessel 100 and the temperature of the conveying mechanism 120 can be locally controlled. Therefore, the reaction apparatus 10 can efficiently control the temperature of the intermediate material and efficiently convert the intermediate material into product R11.

[0084] Although the construction of the reaction apparatus 10 has been described above, the reaction apparatus 10 according to Reference Example 1 is not limited to the above construction. For example, the number of conveying mechanisms 120 can be any number equal to or greater than one, and it can be two or more. That is, the reaction apparatus 10 may include a plurality of parallel conveying mechanisms 120.

[0085] The cross-sectional shape of the reaction vessel 100 in a plane perpendicular to the axis of the conveying mechanism 120 can be a shape having a combination defined by a Reuleaux constant-width figure. In this case, it is desirable that the conveying mechanism 120 is a helix, and the cross-sectional shape of the helix's protrusion 121 can be a shape obtained by combining multiple arcs corresponding to the Reuleaux constant-width figure. For example, if the cross-sectional shape inside the reaction vessel 100 is circular, the cross-sectional shape of the helix can be a Reuleaux constant-width figure composed of three arcs.

[0086] The reaction vessel 100 is not limited to a horizontal parallel orientation, but may have a predetermined angle relative to the horizontal plane, and the reaction vessel 100 may have an inclined surface. Although the reaction apparatus 10 includes a first fluid control region 130 and a second fluid control region 140 in the intermediate portion A3, the reaction apparatus 10 may also have a configuration that allows other fluids to pass through. In other words, the reaction apparatus 10 may have three or more fluid control regions. Alternatively, the reaction apparatus 10 may include only the first fluid control region 130 in the intermediate portion A3. The above-described reaction apparatus 10 is controlled by a control device, which will be described later.

[0087] Subsequently, referring to Figure 2 The function of the reaction apparatus 10 will be explained. Figure 2 This is a block diagram of the reaction apparatus 10 based on Reference Example 1. Besides including... Figure 1In addition to the components shown, the reaction apparatus 10 also includes a control device 200, a temperature control device 210, a first fluid control device 230, a second fluid control device 240, and an information input / output device 250 (information input / output unit 250).

[0088] The control device 200 is a circuit board that includes a computing device, such as a central processing unit (CPU) or a microcontroller unit (MCU). The control device 200 is communicatively connected to and controls each of the temperature control device 210, the first fluid control device 230, the second fluid control device 240, and the information input / output unit 250. The control device 200 implements its functions through hardware and software mounted on the circuit board.

[0089] The control device 200 includes a general control unit 201 as its main functional components, a temperature control unit 202, a conveying control unit 203, a first fluid control unit 204, a second fluid control unit 205, an IF (Interface) control unit 206, and a storage unit 207. These functional components of the control device 200 can be integrated into a single unit or can be discretely configured. These functional components of the control device 200 can be implemented by multiple separate devices working together.

[0090] The overall control unit 201 is connected to the various functional components of the control device 200 and controls the overall operation of these functions. For example, the overall control unit 201 can perform operations such as issuing operating commands to the conveying control unit 203 based on the temperature status supplied from the temperature control unit 202.

[0091] Temperature control unit 202 is connected to temperature control device 210 and controls the temperature of reaction vessel 100 in temperature control zone 110. Temperature control unit 202 includes at least one of a heating device or a cooling device. Temperature control unit 202 may also include one or more thermometers for controlling the temperature.

[0092] The transport control unit 203 is connected to the drive unit 150 and controls the operation of the drive unit 150. The transport control unit 203 may include, for example, a motor drive circuit for driving the motor (motor 151) included in the drive unit 150. The transport control unit 203 may also include a rotation sensor for monitoring the rotational speed of the motor (motor 151).

[0093] A first fluid control unit 204 controls the flow of a first fluid in a first fluid control region 130. More specifically, the first fluid control unit 204 is connected to a first fluid control device 230 and controls the operation of the first fluid control device 230. The first fluid control device 230 includes a first valve 134 for pressurizing the first fluid. A second fluid control unit 205 controls the flow of a second fluid in a second fluid control region 140. More specifically, the second fluid control unit 205 is connected to a second fluid control device 240 and controls the operation of the second fluid control device 240. The second fluid control device 240 includes a second valve 144 for pressurizing the second fluid.

[0094] The IF control unit 206 (IF = Interface) is connected to the information input / output unit 250 and serves as the interface for exchanging information with the user through the information input / output unit 250. Specifically, the IF control unit 206 receives operations performed by the user via the information input / output unit 250 and appropriately provides information related to the received operations to each component of the control device 200. Furthermore, the IF control unit 206 controls the state of the display unit possessed by the information input / output unit 250.

[0095] Storage unit 207 is a storage device that includes non-volatile memory such as flash memory or solid-state drive (SSD). Storage unit 207 stores programs that enable the response device 10 to perform the functions disclosed herein. Storage unit 207 also includes volatile memory and temporarily stores predetermined information when the control device 200 is running. Information input / output unit 250 includes, for example, buttons, switches, touch panels, etc., for receiving operations performed by the user. Information input / output unit 250 also includes a display device, etc., for presenting information to the user.

[0096] The functional blocks of the reaction apparatus 10 have been described above. With the above structure, the reaction apparatus 10 transports the received material to be processed R10 via the conveying mechanism 120, controls the temperature of the reaction vessel 100, and controls the atmosphere in the first fluid control zone 130 and the second fluid control zone 140.

[0097] Subsequently, referring to Figure 3 The method for producing product R11 (product manufacturing method) executed by reaction apparatus 10 will be described. Figure 3 This is a flowchart of the process performed by the reaction device 10. Figure 3 The flowchart shown, for example, begins by supplying the material to be processed, R10, to the reaction apparatus 10.

[0098] First, the reaction apparatus 10 receives the predetermined material to be processed R10 from the supply port 101 (step S11).

[0099] Next, the control device 200 of the reaction apparatus 10 controls the temperature by driving the heating or cooling device in the temperature control zone 110 of the reaction vessel 100 via the temperature control unit 202 (step S12).

[0100] Next, the control device 200 of the reaction apparatus 10 drives the drive device 150 via the transport control unit 203. Therefore, the drive device 150 drives the transport mechanism 120. Then, the transport mechanism 120 transports the received workpiece R10 toward the outlet 102 (step S13).

[0101] Next, the control device 200 of the reaction apparatus 10 controls the flow of the first fluid through the first fluid control region 130 (first atmosphere control region) via the first fluid control unit 204 (step S14).

[0102] Next, the control device 200 of the reaction apparatus 10 controls the flow of the second fluid through the second fluid control region 140 (second atmosphere control region) via the second fluid control unit 205 (step S15).

[0103] Next, the reaction apparatus 10 will discharge the product R11, which has passed through the second fluid control zone 140, from the outlet 102 (step S16).

[0104] The reaction method (product manufacturing method) performed by the reaction apparatus 10 has been described above. The above method is shown along a flow chart, wherein the reaction apparatus 10 manufactures product R11 from the material to be processed R10 and discharges the manufactured product R11. However, the reaction apparatus 10 may, for example, perform temperature control in step S12 before step S11. Furthermore, for example, the reaction apparatus 10 may start steps S14 and S15 simultaneously.

[0105] Reference Example 1 has been described above. Although the reaction apparatus 10 described above includes two fluid control regions (a first fluid control region 130 and a second fluid control region 140), the reaction apparatus 10 may alternatively include one or more fluid control regions. The reaction apparatus 10 may also include an axis AX along the conveying mechanism 120. 120 Multiple temperature control zones 110 in the direction of the major axis. The above-described reaction apparatus 10 brings various fluids into contact with the material to be processed R10 received from the supply port 101 at the intermediate section A3. The reaction apparatus 10 also extends along the axis AX of the conveying mechanism 120 in the intermediate section A3. 120The direction (long axis direction) controls the temperature of the reaction vessel 100. The reaction apparatus 10 can also transport objects within the reaction vessel 100 and provide physical stimulation. The reaction apparatus 10 can simultaneously and precisely perform the above-mentioned atmosphere control, temperature control, and physical control. Therefore, according to Reference Example 1, a reaction apparatus, etc., for efficiently producing desired products can be provided.

[0106] <Reference Example 2>

[0107] Subsequently, as a reference example 2, refer to Figure 4 Hereinafter, an example of the construction of the supporting reaction vessel 100 and the supporting conveying mechanism 120 will be described. This construction example is applicable to the above-described Reference Example 2. Figure 4 This is a side view of the reaction apparatus based on Reference Example 2. Figure 4 Corresponding to the first support portion 103 and the second support portion 104, they are added Figure 1 The diagram shows the composition. Other constructions are similar. Figure 1 The construction of the example is described below. The differences between Reference Example 1 and Reference Example 2 will be explained in detail below.

[0108] <Example of the construction of supporting reaction vessel 100>

[0109] like Figure 4 As shown, the reaction apparatus 10 includes a first support portion 103 and a second support portion 104, which serve as supports for the reaction vessel 100. Figure 4 The shown reaction vessel 100 is a cylindrical reaction vessel (furnace) including a middle portion A3 located between one end side A1 and the other end side A2, which is supported by a first support portion 103 and a second support portion 104 provided on a bottom plate surface 170. The bottom plate surface 170 may be the bottom plate surface of the building on which the reaction device 10 is installed, or it may be, for example, part of the surface forming the structure of the reaction device 10, such as the top surface of the mounting base.

[0110] A first support portion 103, located on the bottom plate surface 170 below one end side A1 of the reaction vessel 100, supports one end side A1 of the reaction vessel 100 from below. Specifically, the first support portion 103 supports one end side A1 of the reaction vessel 100 at a distance from the long axis AX of the reaction vessel 100. 100 The reaction vessel 100 is supported while moving in the direction of the first support 103. This is achieved, for example, by fixing one end A1 of the reaction vessel 100 supported by the first support 103 to the first support 103 by a direct fixing means such as bolts or welding. Alternatively, instead of a direct fixing means, this can be achieved, for example, by bringing a component separately fixed to a mounting base, such as a plate or wire, into contact with one end A1 of the reaction vessel 100 supported by the first support 103, and then indirectly fixing one end A1 of the reaction vessel 100 to the first support 103.

[0111] On the other hand, a second support portion 104, located on the bottom plate surface 170 below the other end side A2 of the reaction vessel 100, supports the other end side A2 of the reaction vessel 100 from below. Specifically, the second support portion 104 supports the other end side A2 of the reaction vessel 100 at a distance from the long axis AX of the reaction vessel 100. 100 It is supported while moving in the direction of [the object]. This is achieved, for example, through specific examples 1-3 described later.

[0112] At the other end A2 of the reaction vessel 100, along its long axis AX... 100 The technical implications of providing support while the object is moving in the same direction are as follows.

[0113] That is, as described in Reference Example 1 above, when the temperature of the reaction vessel 100 is controlled by the temperature control device 210 or the like (for example, when the reaction vessel 100 is heated from the ambient temperature to approximately 900 degrees), the reaction vessel 100 along its long axis AX... 100 Thermal expansion in the direction of (e.g., along the long axis AX) 100 Thermal expansion of approximately 10-20 mm in the direction of AX). At this time, if the other end A2 of the reaction vessel 100 is along the long axis AX... 100 If it cannot move in the direction of AX, then as the reaction vessel 100 moves along its long axis AX... 100 Thermal expansion in the direction of the force exerted on the drive unit 150 can cause damage to the drive unit 150. For example, it is possible that the rotating shaft of one or more gears forming the drive unit 150 (e.g., a reducer) can deform, thus preventing the drive unit 150 (e.g., the reducer) from operating properly. Alternatively, it is possible that the conveying mechanism 120 can deform significantly, preventing the conveying mechanism 120 from performing normal conveying.

[0114] To prevent the reaction vessel 100 from being on its long axis AX 100 Thermal expansion in the direction of the reaction vessel 100 will exert force on the drive unit 150, and in the event that the drive unit 150 is damaged, for example, the second support 104 will support the other end A2 of the reaction vessel 100 on its long axis AX. 100 It provides support while moving in the direction of [the object].

[0115] Next, the other end side A2 of the reaction vessel 100 will be adjusted along its long axis AX. 100 This section provides a specific example of support provided while the object is moving in the direction of movement.

[0116] <Specific Example 1>

[0117] Figure 5AThe figure shows a specific example 1, in which the other end side A2 of the reaction vessel 100 is located on its long axis AX of the reaction vessel 100. 100 It is supported while moving in the direction of . Figure 5A From Figure 4 The arrow in the AR1 view is the direction of the arrow being viewed.

[0118] like Figure 5A As shown, specific example 1 is such an example, in which, in order to make the other end side A2 of the reaction vessel 100 be on the long axis AX of the reaction vessel 100 100 The reaction vessel 100 moves in the direction of the reaction vessel 100, and the other end A2 is supported in this state. A flange 109 is provided on the other end A2 of the reaction vessel 100, and a recess 109a is formed in the lower part of the flange 109. A protrusion 104a is provided in the upper part of the second support 104 and is inserted into the recess 109a. The recess 109a and the protrusion 104a are located along the long axis AX of the reaction vessel 100. 100 It extends in the direction of the flange portion 109. A gap G1 is formed between the bottom surface 109b of the flange portion 109 and the top surface 104b of the second support portion 104. Lubricating oil or the like can be supplied to the portion between the recess 109a and the protrusion 104a. Conversely, the protrusion 104a can be provided in the lower part of the flange portion 109, and the recess 109a into which the protrusion 104a is inserted can be formed in the upper part of the second support portion 104.

[0119] <Specific Example 2>

[0120] Figure 5B The figure shows a specific example 2, in which the other end side A2 of the reaction vessel 100 is located on its long axis AX of the reaction vessel 100. 100 It is supported while moving in the direction of . Figure 5B From Figure 4 The arrow in the AR1 view is the direction of the arrow being viewed.

[0121] like Figure 5B As shown, specific example 2 is such an example, in which, in order to make the other end side A2 of the reaction vessel 100 be on the long axis AX of the reaction vessel 100 100The reaction vessel 100 is moved in the direction of [unclear - possibly "moving" or "moving"]. The other end A2 of the reaction vessel 100 is supported in this state. A flange 109 is provided on the other end A2 of the reaction vessel 100, and a friction-reducing member 111 is provided on the top surface 104b of the second support 104. The bottom surface 109b of the flange 109 contacts the friction-reducing member 111. The shape, form, and material of the friction-reducing member 111 are not particularly limited, as long as it is a member that allows the reaction vessel 100 to move smoothly. The friction-reducing member 111 can be, for example, a member including a rotating part, such as a roller or belt. The friction-reducing component 111 can be a component made of a high-hardness material, such as tool steel that can be heat-treated by quenching, nitrided steel that can be heat-treated by nitriding, powder metallurgy material containing ceramic particles in at least a portion of the friction-reducing component 111, or steel with a coating on its surface. The surface of the friction-reducing component 111 supporting the reaction vessel 100 has a Vickers hardness (HV) of 450 or higher, or a Rockwell hardness (HRC) of 45 or higher. The friction-reducing component 111 can be, for example, a component whose surface is coated with diamond-like carbon (DLC), titanium carbide (TiC), titanium carbonitride (TiB2), titanium boride (TiB2), vanadium carbide (VC), alumina (Al2O3), zirconium oxide (ZrO2), etc., by film-forming means such as CVD, PVD, or hot-melt spraying. The friction-reducing component 111 can also be a component whose surface is coated with chromium or nickel plating (Ni-P or Ni-Co-W) by electroplating or electroless plating. The friction-reducing component 111 may also be a component whose surface is coated with a composition having solid lubricating properties (such as molybdenum disulfide) by means of application such as spraying. That is, the chemical composition of the surface (support surface) of the friction-reducing component 111 supporting the reaction vessel 100 preferably contains at least one element (chemical element) selected from B, C, N, Al, P, Ti, V, Cr, Co, Ni, Mo and W.

[0122] <Specific Example 3>

[0123] Figure 5C The figure shows a specific example 3, in which the other end side A2 of the reaction vessel 100 is located on its long axis AX of the reaction vessel 100. 100 It is supported while moving in the direction of . Figure 5C From Figure 4 The arrow in the AR1 view is the direction of the arrow being viewed.

[0124] like Figure 5C As shown, specific example 3 is such an example, in which, in order to make the other end side A2 of the reaction vessel 100 be axial along the major axis AX of the reaction vessel 100... 100The reaction vessel 100 is moved in the direction of [movement direction], and the other end A2 of the reaction vessel 100 is supported in this state. A flange portion 109 is provided on the other end A2 of the reaction vessel 100, including protrusions 109c and 109d that protrude to the left and right sides (in a direction intersecting (e.g., perpendicular to) the long axis of the reaction vessel 100). Erected portions 104c and 104d are provided on the top surface 104b of the second support portion 104, and the protrusions 109c and 109d are placed on the erected portions 104c and 104d. A gap G2 is formed between the bottom surface 109b of the flange portion 109 and the top surface 104b of the second support portion 104, and gaps G3 and G4 are formed between the left and right sides of the flange portion 109 and the erected portions 104c and 104d. Lubricating oil or the like can be supplied between the protrusions 109c and 109d and the erected portions 104c and 104d.

[0125] Similar to the specific examples 1-3 above, the other end A2 of the reaction vessel 100 is located on its long axis AX. 100 It is supported in a state of moving in the direction of AX, thereby preventing the reaction vessel 100 from being affected by the long axis AX. 100 Thermal expansion (or thermal contraction) in the direction of the drive unit 150 causes a force to be applied to the drive unit 150, and the drive unit 150 is damaged, for example.

[0126] <Example of the construction of the supporting conveying mechanism 120>

[0127] like Figure 4 As shown, the reaction device 10 includes bearings 106 and 107 as a structure for supporting the screw, which serves as a conveying mechanism 120.

[0128] A bearing 106, located at one end A1 of the reaction vessel 100, rotatably supports one end B1 of the conveying mechanism 120. The bearing 106 is, for example, a bearing bushing or a bearing plate. One end B1 of the conveying mechanism 120 is connected (fixed) to the output shaft of the reducer 152. That is, one end B1 of the conveying mechanism 120 is rotatable and its axis AX is not directly on the axis of the conveying mechanism 120. 120 It is supported while moving in the direction of .

[0129] On the other hand, bearing 107 is disposed on the other end side A2 of reaction vessel 100, and is rotatable on the other end side B2 of conveying mechanism 120 and is located on the axis AX of conveying mechanism 120. 120 The bearing 107 is used to support the movement in the direction of the bearing 107. The bearing 107 is an example of the third and sixth support parts of this disclosure. The bearing 107 is, for example, a bearing or bushing. To allow the other end side B2 of the conveying mechanism 120 to be positioned along the axis AX of the conveying mechanism 120... 120 Move in the direction of, within a predetermined range on the other end B2 of the conveying mechanism 120 (refer to...) Figure 4 The spiral-shaped protrusion 121 is not provided within the range indicated by the symbol L1 in the diagram. Furthermore, a section is provided between the end of the conveying mechanism 120 on the other end side B2 and the cover 108 provided on the other end side A2 of the reaction vessel 100, such that the axis AX of the conveying mechanism 120 is aligned with the axis of the conveying mechanism 120. 120 direction ( Figure 4 The space entered by the other end B2 of the moving conveyor mechanism 120 (see right side) (refer to the space). Figure 4 (The range indicated by the symbol L2 in the text).

[0130] The axis AX of the conveying mechanism 120 supported as described above 120 and the major axis AX of reaction vessel 100 100 They are consistent with each other (roughly consistent).

[0131] On the other end B2 of the conveying mechanism 120, along its axis AX... 120 The technical significance of providing support while the object is moving in the same direction is as follows.

[0132] That is, as described in Reference Example 1 above, when the temperature of the reaction vessel 100 is controlled by the temperature control device 210 or the like (for example, when the reaction vessel 100 is heated from the ambient temperature to approximately 900 degrees Celsius), the reaction vessel 100 along its long axis AX... 100 Thermal expansion in the direction of (e.g., along the long axis AX) 100 It expands by approximately 10-20 mm in the direction of [the expansion direction]. Simultaneously, the conveying mechanism 120 also expands along its axis AX. 120 Thermal expansion in the direction of (e.g., along the axis AX) 120 Thermal expansion of approximately 10-20 mm in the direction of AX). At this time, if the other end B2 of the conveying mechanism 120 is on axis AX... 120 If it cannot move in the direction of AX, then the conveying mechanism 120 can move because the conveying mechanism 120 is on the axis AX. 120 The thermal expansion in the direction of the deformation causes the protrusion 121 of the deformed conveying mechanism 120, which has a spiral shape or the like, to come into contact with the inner wall of the reaction vessel 100, thereby preventing the conveying mechanism 120 from rotating normally, for example.

[0133] Furthermore, if one end B1 of the conveying mechanism 120 is designed to be able to be on the axis AX of the conveying mechanism 120 120 It moves in the direction of, and the other end B2 of the conveying mechanism 120 is designed to be non-movable along the axis AX of the conveying mechanism 120. 120 If the conveying mechanism 120 moves in the direction of the spiral, the other end B2 of the conveying mechanism 120 moves with the thermal expansion or contraction of the reaction vessel 100, making it difficult to control the position of the convex and concave parts of the spiral, and the material to be processed may not react normally.

[0134] To prevent the conveying mechanism 120 from being on axis AX 120 The other end B2 of the conveying mechanism 120 is rotatably supported by a bearing 107 and is located on the axis AX of the conveying mechanism 120. 120 It provides support while moving in the direction of [the object].

[0135] As described above, the other end side B2 of the conveying mechanism 120 is rotatable and its axis AX is within the conveying mechanism 120. 120 Support is provided while the conveying mechanism 120 is moving in the direction of AX to prevent it from being damaged due to its axis AX. 120 It deforms due to thermal expansion in the direction of the direction.

[0136] As described above, according to Reference Example 2, a reaction apparatus 10 can be provided, even when the reaction vessel 100 is on its long axis AX. 100 When thermal expansion occurs in the direction of thermal expansion, the reaction apparatus can also prevent the reaction vessel 100 from malfunctioning due to thermal expansion.

[0137] Next, we will explain the variations.

[0138] Although an example of using a non-rotatably supported reaction vessel 100 has been described in Reference Example 2 above, this is merely an example. For instance, a rotatably supported reaction vessel 100 may be used instead.

[0139] Figure 6 This is a construction example of a reaction vessel 100 that can be rotatably supported.

[0140] like Figure 6 As shown, the reaction apparatus 10 according to this modified example includes bearings 112 and 113 as components for rotatably supporting the reaction vessel 100.

[0141] The bearing 112, disposed between one end A1 of the reaction vessel 100 and the first support 103, is rotatably disposed on one end A1 of the reaction vessel 100 and is not located on the long axis AX of the reaction vessel 100. 100 The bearing 112 is supported while moving in the direction of the reaction vessel 100. The bearing 112 is, for example, a bearing or bushing. A flange 114 is provided at one end A1 of the reaction vessel 100. This flange 114 contacts the bearing 112, preventing the one end A1 of the reaction vessel 100 from being supported by the long axis AX of the reaction vessel 100. 100 direction ( Figure 6The reaction vessel 100 can move on its right side. Multiple flanges 114 and multiple bearings 112 can be provided. For example, by providing two bearings 112 for one flange 114 and clamping the flange 114 with these bearings 112, it is more preferable to prevent one end side A1 of the reaction vessel 100 from moving along the long axis AX of the reaction vessel 100. 100 The bearing 112 can be an annular bearing or bushing inserted into one end side A1 of the reaction vessel 100, or it can be an arc-shaped bearing or bushing with a portion of the annular bearing or bushing cut off. Instead of bearing 112, a component made of lubricating material can be used to rotatably support one end side A1 of the reaction vessel 100 and is not allowed to move along the long axis AX of the reaction vessel 100. 100 It is supported while moving in the direction of movement. The bearing 112 and the flange 114 are examples of the fourth support portion of this disclosure.

[0142] On the other hand, the bearing 113, which is disposed between the other end A2 of the reaction vessel 100 and the second support 104, is rotatably disposed relative to the other end A2 of the reaction vessel 100 and is located on the long axis AX of the reaction vessel 100. 100 The bearing 113 is supported in a state of movement in the direction of the reaction vessel 100. The bearing 113 is, for example, a bearing or bushing. The bearing 113 may be an annular bearing or bushing inserted into the other end side A2 of the reaction vessel 100, or it may be an arc-shaped bearing or bushing with a portion of the annular bearing or bushing cut off. Instead of the bearing 113, a component made of lubricating material may be used to rotatably support the other end side A2 of the reaction vessel 100 and in its position along the long axis AX of the reaction vessel 100. 100 The bearing 113 is an example of the fifth support in this disclosure. According to this variation, the rotatably supported reaction vessel 100 is connected (linked) at one end A1 to a reaction vessel drive device 116 identical to the drive device 150 (screw drive device). Figure 6 (Not shown in the image).

[0143] In the case where the reaction vessel 100 is rotatably supported as in the modified example, a rotatably supported conveying mechanism 120 (see reference) can be used. Figure 4 Alternatively, a non-rotatably supported conveying mechanism 120 (not shown) can be used instead of a rotatably supported conveying mechanism 120. Furthermore, the conveying mechanism 120 may be omitted.

[0144] Furthermore, although the example of using a first support portion 103 supporting one end side A1 of the reaction vessel 100 below as a first support portion has been described in Reference Example 2 above, this is merely an example. That is, the first support portion can have any construction, as long as it supports one end side A1 of the reaction vessel 100 in a manner that prevents it from being positioned on the main shaft AX. 100The container can be supported while moving in the direction of the reaction vessel. For example, although not shown in the figure, the first support portion that supports one end side A1 of the reaction vessel 100 can be used as the first support portion, which suspends one end side A1 of the reaction vessel 100 from above. Alternatively, the first support portion that supports one end side A1 of the reaction vessel 100 from the side can be used.

[0145] Furthermore, although an example of using the support portion supporting the other end side A2 of the bottom of the reaction vessel 100 as a second support portion 104 has been described in Reference Example 2 above, this is merely an example. That is, the second support portion can have any construction, as long as the second support portion is positioned relative to the other end side A2 of the reaction vessel 100 on its long axis AX. 100 The container can be supported while moving in the direction of the reaction vessel. For example, although not shown in the figure, a second support portion that supports the other end A2 of the reaction vessel 100 from above can be used as a second support portion, or a second support portion that supports the other end A2 of the reaction vessel 100 from the side can be used.

[0146] Although Figure 5A and 7 As shown in the above-described reference example, such an example is illustrated, wherein the second support 104 is located on the other end A2 of the reaction vessel 100, which is only accessible along the long axis AX of the reaction vessel 100. 100 It provides support while moving in the direction of [the object], but this is just an example. Figure 7 From Figure 5A The arrow view is viewed in the direction of arrow AR2. For example, the other end side A2 of reaction vessel 100, in addition to being visible along the long axis AX of reaction vessel 100, is also visible. 100 In addition to moving in the direction of rotation, it can also move around its rotational axis AX. V It is supported while rotating (the vertical axis).

[0147] Next, a specific example 4 will be described, in which the other end A2 of the reaction vessel 100, in addition to being on the long axis AX of the reaction vessel 100, is... 100 In addition to moving in the direction of rotation, it can also move around its axis of rotation AX. V It is supported while rotating (the vertical axis).

[0148] <Specific Example 4>

[0149] Figure 8 This is a schematic diagram of specific example 4, in which the other end A2 of the reaction vessel 100, besides being on the long axis AX of the reaction vessel 100, is... 100 In addition to moving in the direction of rotation, it can also move around its axis of rotation AX. VIt is supported while rotating (the vertical axis).

[0150] like Figure 8 As shown, a protrusion 104a is provided on a base 104e, which is supported by a second support 104 (top surface 104b) via a bearing or the like, thereby allowing rotation about the axis AX. V Rotate (along the vertical axis). Note that in Figure 8 In the middle, the axis of rotation AX V It extends in a direction perpendicular to the plane of the paper. Therefore, the other end side A2 of the reaction vessel 100, in addition to being on the long axis AX of the reaction vessel 100, also extends in a direction perpendicular to the plane of the paper. 100 In addition to moving in the direction of rotation, it can also move around its axis of rotation AX. V It is supported while rotating (the vertical axis).

[0151] As described above, in addition to the long axis AX of the reaction vessel 100 100 In addition to moving in the direction of rotation, it also moves to the other end side A2 of the reaction vessel 100 about its rotational axis AX. V The advantages of supporting the structure while rotating (vertical axis) are as follows.

[0152] That is, in Figure 7 In this process, based on the state of the reaction (the state of the physical stimulus), the long axis AX of the reaction vessel 100 can be... 100 There is a temperature difference between the temperature on the right side and the temperature on the left side (or a temperature difference can be intentionally created). In this case, the long axis AX of the reaction vessel 100... 100 The phenomenon that the extension on the right side is different from the extension on the left side.

[0153] For example, in Figure 7 In the middle, when the major axis AX of the reaction vessel 100 100 When the temperature on the right side is higher and the temperature on the left side is lower, the long axis AX of the reaction vessel 100 100 The right side extends longer, while the left side extends shorter. Figure 7 The lengths of the middle arrows AR3 and AR4 indicate this situation.

[0154] When the major axis AX of reaction vessel 100 100 When the extension on the right side and the extension on the left side are different from each other, horizontal stress can be generated on the other end A2 of the reaction vessel 100 (refer to...). Figure 7 (Arrow AR5 in the image).

[0155] When the aforementioned stress is generated, the friction generated between the second support portion 104 (protrusion 104a) and the flange portion 109 (recess 109a) can hinder the reaction vessel 100 (the other end A2) from moving along its long axis AX. 100 It moves in the direction of.

[0156] By adopting Figure 8 The structure shown can appropriately respond to various situations of physical stimuli.

[0157] When using a biaxial reaction vessel 100A (refer to...) Figure 9 When a temperature difference is intentionally created between the temperature on the right side of the reaction vessel 100 and the temperature on its left side, it is particularly effective for controlling, for example, the reaction rate of the substance to be processed. Figure 9 This is an example of a biaxial reaction vessel 100A.

[0158] Next, a specific example 5 will be described, in which the other end A2 of the reaction vessel 100, in addition to being on the long axis AX of the reaction vessel 100, is... 100 In addition to moving in the direction of the axis, it is also supported so that it can move in the direction of the minor axis (see reference). Figure 10 (Arrow AR6 in the image).

[0159] <Specific Example 5>

[0160] Figure 10 This is a schematic diagram of specific example 5, in which the other end A2 of the reaction vessel 100, besides being on the long axis AX of the reaction vessel 100, is... 100 In addition to moving in the direction of its minor axis, it can also move in the direction of its minor axis (see reference). Figure 10 It is supported while moving along the arrow AR6 in the middle.

[0161] like Figure 10 As shown, a protrusion 104a is provided on a base 104e, which is supported by a second support 104 (top surface 104b) via bearings or the like, allowing it to rotate around the axis AX. V (Vertical axis) Rotation. Furthermore, the base 104e is mounted on the guide rail 104f (supported by the second support 104 (top surface 104b)), allowing it to also rotate in the short axis direction (see...). Figure 10 Move along the arrow AR6 in the diagram. Note that... Figure 10 In the middle, the axis of rotation AX V It extends in a direction perpendicular to the plane of the paper. Therefore, the other end side A2 of the reaction vessel 100, in addition to being on the long axis AX of the reaction vessel 100, also extends in a direction perpendicular to the plane of the paper. 100 In addition to moving in the direction of rotation, it can also move around its axis of rotation AX. V (Vertical axis) Rotates and can be rotated in the minor axis direction (refer to) Figure 10 It is supported while moving along the arrow AR6 in the middle.

[0162] As described above, in addition to the long axis AX of the reaction vessel 100 100 In addition to moving in the direction of rotation, the other end A2 of the reaction vessel 100 can rotate around the axis AX.V (Vertical axis) Rotates and can be rotated in the minor axis direction (refer to) Figure 10 The advantages of being supported while moving along the arrow AR6 are as follows.

[0163] When the above stress is generated (refer to) Figure 7 In the case of arrow AR5, the friction generated between the second support 104 (protrusion 104a) and the flange 109 (recess 109a) will hinder the reaction vessel 100 (other end A2) from moving along its long axis AX. 100 Movement in the direction of.

[0164] When the aforementioned deformation becomes larger (when the aforementioned stress becomes larger), the other end A2 of the reaction vessel 100 can be tilted (see reference). Figure 11B And the reaction vessel 100 is flexible (see reference). Figure 11A ). Figure 11A It is a diagram showing the state of the reaction vessel under 100 degrees of deflection. Figure 11B This is a diagram showing the tilted state of reaction vessel 100. Deflection and tilting are prone to occur at the other end A2 or in the middle A3.

[0165] To solve the above problems, by adopting Figure 10 The structure shown can suppress the deflection of the reaction vessel 100 (see reference). Figure 11C and 11D ). Figure 11C This is a diagram showing the state in which the flexural deformation of the reaction vessel 100 is suppressed. Figure 11D This is a diagram showing the state in which the tilt of the reaction vessel 100 is suppressed.

[0166] Furthermore, although such examples have been described in the above-mentioned Reference Examples 1 and 2, in which the temperature control unit (temperature control zone 110, etc.) is directed at the long axis AX of the reaction vessel 100 100 The temperature of the reaction vessel 100 is controlled by different regions in different directions, but this is just an example. That is, the number of regions controlled by the temperature control unit (temperature control region 110, etc.) is not limited to two or more, and can be one.

[0167] Furthermore, although examples of using a fluid supply unit (first fluid inlet 131, first fluid outlet 132, first valve 134, etc.) have been described in the above-mentioned Reference Examples 1 and 2, these are merely examples. That is, some or all of the fluid supply unit (first fluid inlet 131, first fluid outlet 132, first valve 134, etc.) may be omitted.

[0168] Furthermore, although examples of a drive device 150 disposed at one end A1 of the reaction vessel 100 and connected to one end B1 of the conveying mechanism 120 (e.g., a screw) have been described in Reference Examples 1 and 2 above, these are merely examples. Another drive device may be used as a means of driving the conveying mechanism 120.

[0169] <Implementation Method>

[0170] <Specific example of temperature control zone 110>

[0171] First, specific examples of the temperature control zone 110 common to the reaction apparatuses 10A, 10B and 10C according to the first to third embodiments will be described below.

[0172] Figure 12 This is a perspective view of temperature control area 110.

[0173] like Figure 12 As shown, the temperature control region 110 is located on the long axis AX of the reaction vessel 100. 100 The direction is divided into a total of three regions D1-D3. The temperature control region 110 is not limited to being divided into three regions, but can be divided into one, two, four or more regions.

[0174] Region D1 is located around the long axis AX of the reaction vessel 100. 100 The surrounding area (circumferential direction) is divided into a total of four regions D11-D14 (i.e., upper, lower, left, and right). Region D1 is not limited to being divided into four regions, but can be divided into 1-3 or 5 regions. The same applies to regions D2 and D3.

[0175] Then, the first heating section H1, the second heating section H2, the third heating section H3, and the fourth heating section H4 are respectively arranged in four regions D11-D14. In this way, the heating sections H1-H4 surround the long axis AX of the reaction vessel 100. 100 Set to surround the reaction vessel 100.

[0176] Considering temperature control characteristics, it is desirable that the heating parts H1-H4 are heaters (electric heaters) containing heating wires.

[0177] Figure 13 This is a block diagram showing the electrical connections between the heating units H1-H4 and the temperature control unit 202. (See diagram below.) Figure 13 As shown, each heater in the heater is electrically connected to the temperature control unit 202. Note that the heating units H1-H4 are not limited to heaters, but can also be other heating means.

[0178] Although not shown in the figure, temperature measuring units are located in four areas D11-D14. It is desirable that the temperature measuring units are, for example, thermocouples. Each temperature measuring unit is electrically connected to the temperature control unit 202. Note that the temperature measuring units are not limited to thermocouples, but can also be other temperature measuring units (temperature sensors).

[0179] The temperature control unit 202 controls the temperature of multiple sections (12 sections) of the reaction vessel 100 (intermediate section A3) corresponding to each region by controlling (for example, performing PID control) the current flowing through each heater (heating wire). At this time, the temperature control unit 202 references the temperature measured by the corresponding temperature measuring unit. For example, when the temperature control unit 202 controls the temperature of the section of the reaction vessel 100 corresponding to region D11 by controlling the heater (which is the first heating section H1 in region D11), the temperature control unit 202 references the temperature measured by the temperature measuring unit provided in region D11. The same applies to controlling the other heaters, i.e., the other heating sections H2-H4.

[0180] Note that the location (object) measured by the temperature measuring unit may be a heater arranged in the area where the temperature measuring unit is arranged, a part of the reaction vessel 100 corresponding to the area where the temperature measuring unit is arranged, the space between the heater and the reaction vessel 100 arranged in the area where the temperature measuring unit is arranged, or other locations (objects).

[0181] As described above, in the reaction apparatuses 10A, 10B, and 10C according to the first to third embodiments described later, the temperature control zone 110 is divided into a total of 12 zones represented by 3×4, and the temperature of each of the 12 portions of the reaction vessel 100 (middle portion A3) corresponding to the respective zone can be controlled. Therefore, the reaction apparatuses 10A, 10B, and 10C can more preferably realize the reaction of the raw materials.

[0182] <Modification of reaction vessel 100>

[0183] Next, the deformation of the reaction vessel 100 will be explained.

[0184] Figure 14 An example of a deformation mode of the reaction vessel 100 is shown.

[0185] When the temperature of the reaction vessel 100 is controlled (heating control or cooling control), the reaction vessel 100 is along its long axis AX. 100 It expands or contracts in the direction of [the object]. At this time, as [the object]... Figure 4As shown, one end A1 of the reaction vessel 100 is supported by the first support 103 (fixed support) when it is immovable, while the other end A2 is supported by the second support 104 (movable support) when it is movable. Therefore, when the temperature of the reaction vessel 100 is controlled (heating control or cooling control), as... Figure 14 As shown, the other end A2 of the reaction vessel 100 is positioned relative to one end A1 along its long axis AX. 100 Displacement in the direction (refer to) Figure 14 (arrow).

[0186] <First Question (Problem when reaction vessel 100 is under cooling control)>

[0187] Next, the first problem will be explained (the problem when the reaction vessel 100 is under cooling control).

[0188] Figure 15 This diagram is used to illustrate the first problem (the problem when the reaction vessel 100 is under cooling control).

[0189] When the reaction vessel 100 is subjected to cooling control, the reaction vessel 100 is cooled earlier than the conveying mechanism 120. Therefore, the reaction vessel 100 is cooled earlier along the long axis AX than the conveying mechanism 120. 100 contract in the direction (refer to) Figure 15 (Arrow AR7 in the image), and the other end side A2 of the reaction vessel 100 is on the long axis AX. 100 The direction toward one end A1 ( Figure 15 Displacement (left side in the middle) (refer to) Figure 15 (Arrow AR7 in the image). Therefore, the interference space S1 between the cover 160 on the other end A2 of the reaction vessel 100 and the conveying mechanism 120 (on the other end B2) (see arrow AR7 in the image). Figure 15 The space gradually narrows. Then, the conveying mechanism 120 (on the other end, B2) eventually contacts the cover 160. This leads to a problem that may hinder the normal operation of the reaction apparatus 10A-10C (the reaction apparatus 10A-10C may fail) (the first problem).

[0190] Ideal temperature conditions

[0191] When considering the first problem mentioned above, it is desirable that the temperature control unit 202 controls each heater (heating wire) respectively, so that the upper part A, lower part C, left part D and right part B of the reaction vessel 100 (refer to) Figure 12 The temperature difference between them should be minimized.

[0192] Specifically, the temperature difference between the upper part A, lower part C, left part D and right part B of the reaction vessel 100 is preferably within ±20°C, and more preferably within ±10°C.

[0193] Next, the process of cooling the temperature of the reaction vessel 100 (upper part A, lower part C, left part D and right part B) from the current temperature (e.g., 1000°C) to the target temperature (e.g., 500°C) will be described.

[0194] During this process, the temperature control unit 202 individually controls each heater (heating wire) in such a way that the temperature of the reaction vessel 100 (upper part A, lower part C, left part D and right part B) changes from the current temperature (e.g. 1000°C) to the target temperature (e.g. 500°C).

[0195] At this point, in order to reduce the temperature difference between the upper part A, lower part C, left part D, and right part B of the reaction vessel 100, it is desirable that the cooling rate of the reaction vessel 100 (upper part A, lower part C, left part D, and right part B) be as low as possible. Specifically, the cooling rate of the reaction vessel 100 (upper part A, lower part C, left part D, and right part B) is preferably 10°C / min or lower, more preferably 5°C / min or lower, and even more preferably 2°C / min or lower. For example, this desired cooling rate can be obtained through experience, experimentation, or predetermined calculation. By adopting this desired cooling rate as the cooling rate of the reaction vessel 100 (upper part A, lower part C, left part D, and right part B), the aforementioned first problem can be solved.

[0196] <Second Question (Problem when reaction vessel 100 is under cooling control)>

[0197] exist Figure 4 In the reaction apparatus 10 shown in Reference Example 2, when the reaction vessel 100 is subjected to cooling control, the cooling is typically performed in stages. The same applies to the case where the reaction vessel 100 is subjected to heating control in the reaction apparatus 10 of Reference Example 2.

[0198] Figure 16A This shows an example of a phased cooling process. Figure 16B This shows an example of a phased warming trend. Figure 17 This is a graph showing the relationship between the temperature change C1 during cooling control (cooling control) of the reaction vessel 100 to the target temperature at a certain cooling rate in the reaction apparatus 10 of Reference Example 2, and the actual temperature change C2 of the reaction vessel 100.

[0199] exist Figure 4 The reason for the phased cooling in the reaction apparatus 10 of Reference Example 2 shown is as follows.

[0200] That is, such as Figure 17 As shown, when the temperature of the reaction vessel 100 is controlled to decrease to the target temperature at a certain cooling rate (cooling control), before the temperature finally reaches the target temperature (e.g., referring to...), Figure 17 The displacement ΔX' (on the long axis AX of reaction vessel 100) occurs at time T1 and cannot follow the temperature change C1 (time axis). 100 (The displacement in the direction). Therefore, phased cooling control is required, and the standby time T is set. W (Reference Figure 17 ), to wait until the long axis AX of reaction vessel 100 100 The displacement in the direction is called ΔX.

[0201] exist Figure 17 In the diagram, the symbol ΔX represents the temperature at which the target temperature is reached in the reaction vessel 100 (in...). Figure 17 The case shown is at an intermediate temperature (temperature difference of ΔT) at the long axis AX of reaction vessel 100. 100 The amount of displacement in the direction. Figure 17 The symbol ΔX' in the figure represents the displacement of the temperature change C1 (time axis) that cannot follow the cooling at time T1 (on the major axis AX of reaction vessel 100). 100 The displacement in the direction), and time T1 is the time before the temperature reaches the target temperature. Figure 17 The symbol X2 in the text corresponds to Figure 19 Position X2, symbol X3 corresponds to Figure 19 Position X3 in the middle.

[0202] However, due to the aforementioned standby time T W The time is mainly set manually based on experience, so the "extra standby time T" occurs. EX ” (refer to Figure 17 Therefore, there is a problem that the time (cooling time) until the temperature of the reaction vessel 100 (upper A, lower C, left D and right B) reaches the target temperature becomes longer (e.g., taking several days) (the second problem).

[0203] Next, refer to Figure 18 To further explain the second question mentioned above.

[0204] Figure 18 An example flowchart is shown for a cooling process used to perform staged cooling in the reaction apparatus 10 of Reference Example 2.

[0205] First, set the current temperature T1 (e.g., 1000℃), the target temperature T2 (e.g., 500℃), the cooling rate Vt (e.g., 10℃ / min), and the intermediate temperature Tm (e.g., 750℃) (steps S20-S22). These are, for example, set manually by the operator.

[0206] Next, the temperature is reduced at a rate of Vt (step S23). This is achieved by the temperature control unit 202 controlling each heater to change the temperature of the reaction vessel 100 from the current temperature T1 to the intermediate temperature Tm.

[0207] Next, when the temperature of the reaction vessel 100 has reached the intermediate temperature Tm (e.g., 750°C) (step S24: Yes), the operation waits for a preset standby time T. W (Reference Figure 17 (Step S25: No). During standby time T W During this period, maintain the intermediate temperature Tm.

[0208] Subsequently, after the preset standby time T... W (Step S25: Yes) When the temperature drops, it is reduced at a rate of Vt (Step S26). This is achieved by the temperature control unit 202 controlling each heater to bring the temperature of the reaction vessel 100 to the target temperature T2.

[0209] After the temperature of the reaction vessel 100 reaches the target temperature T2 (step S27: Yes), the cooling process ends (steps S20-S27).

[0210] As described above, when the reaction apparatus 10 of Reference Example 2 undergoes phased cooling, an "extra standby time T" occurs in step S25. EX ” (refer to Figure 17 Therefore, there is a problem that the cooling time of the reaction vessel 100 (upper part A, lower part C, left part D and right part B) becomes longer (for example, cooling the reaction vessel 100 takes several days) (the second problem).

[0211] <First Implementation Method>

[0212] Subsequently, as a first embodiment, a construction example 1 for solving the second problem described above will be described. Hereinafter, the reaction apparatus according to the first embodiment will be referred to as reaction apparatus 10A.

[0213] Figure 19 This is a schematic structural diagram of the reaction apparatus 10A according to the first embodiment. Figure 20 This is a block diagram of the reaction apparatus 10A according to the first embodiment.

[0214] like Figure 19 and Figure 20As shown, the reaction apparatus 10A of the first embodiment corresponds to the apparatus formed by adding a position measuring device 260, a first displacement velocity calculation unit 208, and a second displacement velocity calculation unit 209 to the reaction apparatus 10 of Reference Example 2. In the following text, configurations identical to those of the reaction apparatus 10 of Reference Example 2 are indicated by the same reference numerals, and their descriptions are appropriately omitted.

[0215] The position measuring device 260 measures the actual position of a specific part of the reaction vessel 100 as described above (refer to...). Figure 14 This specific location is, for example, the other end A2 of the reaction vessel 100. Figure 19 The point indicated by the symbol E (hereinafter referred to as point E). Note that this specific location can be any location other than point E. The case where this specific location is point E of reaction vessel 100 will be explained below. Figure 19 In the diagram, positions X1-X3 show examples of the positions of point E as measured by the position measuring device 260. Position X1 shows the position of point E when the temperature of the reaction vessel 100 is room temperature. Position X2 shows the position of point E when the temperature of the reaction vessel 100 is 500°C. Position X3 shows the position of point E when the temperature of the reaction vessel 100 is 1000°C.

[0216] The position measuring device 260 is, for example, a laser displacement meter. The laser displacement meter is mounted on the base plate 170 on which the reaction device 10A is located. The laser displacement meter is based on the base plate position X0 (refer to...). Figure 19 Determine the position of point E, which has been displaced as described above. Figure 19 In this context, the symbol "Ray" represents the laser beam emitted by the laser displacement meter. Note that the position measuring device 260 is not limited to a laser displacement meter, but can be a strain gauge, or a combination of a laser displacement meter and a strain gauge.

[0217] When the temperature of the reaction vessel 100 (intermediate section A3) is controlled from the current temperature T1 to the target temperature T2 at a desired cooling rate (or heating rate), the first displacement velocity calculation unit 208 calculates the displacement velocity (desired displacement velocity V1) of point E of the reaction vessel 100. At this time, the first displacement velocity calculation unit 208 calculates this by, for example, considering the desired cooling rate (or heating rate) and material properties (e.g., the coefficients of thermal expansion of each component forming the reaction vessel 100). This desired displacement velocity V1 (calculated value) can be obtained, for example, through... Figure 21 The line C3 is used to represent this. Figure 21This is a graph showing the relationship between the desired displacement velocity C3 and the actual displacement velocity C4 of point E when the reaction vessel 100 is under cooling control (cooling control). The first displacement velocity calculation unit 208 is implemented, for example, by executing a predetermined program through the control device 200. The first displacement velocity calculation unit 208 is not limited to being implemented by a predetermined program, but may also be implemented by hardware. The calculations performed by the first displacement velocity calculation unit 208 can be performed manually.

[0218] The second displacement velocity calculation unit 209 calculates the actual displacement velocity V2 of point E (a specific location) based on the actual position of point E (measured at multiple positions at different times) measured by the position measuring device 260. The actual displacement velocity V2 (measured value) of point E can be, for example, calculated by... Figure 21 Curve C4 in the figure represents this. The second displacement velocity calculation unit 209 is implemented, for example, by the control device 200 executing a predetermined program. Note that the second displacement velocity calculation unit 209 is not limited to being implemented by a predetermined program, but can also be implemented by hardware.

[0219] The temperature control unit 202 performs a cooling rate control process (or heating rate control process) to control the cooling rate (or heating rate) of the reaction vessel 100 (intermediate part A3) so that the actual displacement velocity V2 of point E follows (matches) the desired displacement velocity V1 of point E. This cooling rate control process (and heating rate control process) will be described later. The temperature control unit 202 is implemented, for example, by executing a predetermined program via the control device 200. Note that the temperature control unit 202 is not limited to being implemented by a predetermined program and can also be implemented by hardware.

[0220] <Example 1 of the operation of reaction device 10A>

[0221] Subsequently, referring to Figure 22 Example 1 of the operation of the reaction apparatus 10A will be described.

[0222] Figure 22 This is a flowchart of an example of the operation of reaction apparatus 10A.

[0223] In the following text, as an example of operation of the reaction apparatus 10A, an example of operation will be described when the temperature of the reaction vessel 100 is controlled (cooled) to decrease from the current temperature of 1000°C to the target temperature of 500°C.

[0224] First, set the current temperature T1 (1000℃), the target temperature T2 (500℃), and the desired cooling rate Vt (e.g., 1℃ / min) (steps S30-S31). This is, for example, set manually by the operator.

[0225] Subsequently, the desired displacement velocity V1 is calculated (step S32). This is performed, for example, by the first displacement velocity calculation unit 208. Specifically, when the temperature of the reaction vessel 100 (intermediate part A3) is controlled to change from the current temperature T1 to the target temperature T2 at a desired cooling rate Vt, the first displacement velocity calculation unit 208 calculates the displacement velocity (desired displacement velocity V1) of point E of the reaction vessel 100. At this time, the first displacement velocity calculation unit 208 calculates, for example, by taking into account the desired cooling rate Vt and material properties (e.g., the coefficients of thermal expansion of each component forming the reaction vessel 100). This desired displacement velocity V1 (calculated value) can be obtained, for example, by... Figure 21 The line C3 in the diagram represents this.

[0226] Next, the position of point E is measured and the actual displacement velocity V2 (measured value) is calculated (step S33). This is performed by the second displacement velocity calculation unit 209. Specifically, the second displacement velocity calculation unit 209 calculates the actual displacement velocity V2 of point E based on the actual position of point E (a specific location) measured by the position measuring device 260 (multiple positions measured at different times). The actual displacement velocity V2 (measured value) of point E can be calculated, for example, by... Figure 21 Curve C4 in the figure represents this.

[0227] Subsequently, a cooling rate control process (step S34) is performed. This cooling rate control process is used to control the cooling rate of the reaction vessel 100 (intermediate part A3) so that the actual displacement velocity V2 of point E calculated in step S33 follows (matches) the desired displacement velocity V1 of point E calculated in step S32, and this process is implemented by the temperature control unit 202.

[0228] Reference Figure 23 The cooling rate control process (step S34) will be described in detail. Figure 23 This is a flowchart of the cooling rate control process.

[0229] like Figure 23 As shown, firstly, it is determined whether the actual displacement velocity V2 and the desired displacement velocity V1 deviate from each other (for example, whether the difference between the actual displacement velocity V2 and the desired displacement velocity V1 exceeds a threshold) (step S341). This is determined, for example, by the temperature control unit 202 comparing the actual displacement velocity V2 of point E calculated in step S33 with the desired displacement velocity V1 of point E calculated in step S32.

[0230] As a result, when the actual displacement velocity V2 and the desired displacement velocity V1 deviate from each other (step S341: yes) and this deviation is a positive deviation (refer to...) Figure 21When arrow AR8 (step S342: Yes) is displayed, it means that the actual displacement velocity V2 of point E is slower than the desired displacement velocity V1 of point E. In this case, the cooling rate of the reaction vessel 100 (upper A, lower C, left D, and right B) is increased (step S343). For example, the temperature control unit 202 increases the cooling rate from 1°C / min to 2°C / min. Specifically, the temperature control unit 202 controls each heater so that the actual displacement velocity V2 of point E follows (matches) the desired displacement velocity V1 of point E. Therefore, the actual displacement velocity V2 of point E follows the desired displacement velocity V1 of point E (refer to...). Figure 21 ).

[0231] On the other hand, when the actual displacement velocity V2 and the desired displacement velocity V1 deviate from each other (step S341: yes) and the deviation is a negative deviation (refer to...) Figure 21 When arrow AR9 appears (step S342: No), it means that the actual displacement velocity V2 of point E is faster than the desired displacement velocity V1 of point E. In this case, the cooling rate of the reaction vessel 100 (upper A, lower C, left D, and right B) is reduced (step S344). For example, the temperature control unit 202 reduces the cooling rate from 2°C / min to 1°C / min. Specifically, the temperature control unit 202 controls each heater so that the actual displacement velocity V2 of point E follows (matches) the desired displacement velocity V1 of point E. Therefore, the actual displacement velocity V2 of point E follows the desired displacement velocity V1 of point E (refer to...). Figure 21 ).

[0232] When the actual displacement velocity V2 and the desired displacement velocity V1 are not deviated from each other (step S341: no), the processing after step S341 is not performed.

[0233] Repeat steps S33 and S34 above until the temperature of the reaction vessel 100 reaches the target temperature T2 set in step S30 (step S35: No).

[0234] Then, when the temperature of the reaction vessel 100 reaches the target temperature T2 (step S35: yes), the operation of the reaction apparatus 10A is terminated, as in Example 1.

[0235] As described above, using the operating example 1 of the reaction apparatus 10A, the actual displacement velocity V2 of point E follows the desired displacement velocity V1 of point E until the temperature of the reaction vessel 100 reaches the target temperature T2 (refer to...). Figure 21 Therefore, the second problem mentioned above has been solved.

[0236] <Example 2 of the operation of reaction device 10A>

[0237] Subsequently, referring to Figure 24Example 2 of the operation of the reaction apparatus 10A will be described. Example 1 of the operation of the reaction apparatus 10A is an example of the cooling control of the reaction vessel 100, while Example 2 of the operation of the reaction apparatus 10A is an example of the heating control of the reaction vessel 100.

[0238] Figure 24 This is a flowchart of an example 2 of the operation of reaction apparatus 10A.

[0239] In the following text, as an example 2 of the operation of the reaction apparatus 10A, an example of operation will be described when the temperature of the reaction vessel 100 is controlled (heated) to rise from the current temperature of 500°C to the target temperature of 1000°C.

[0240] First, set the current temperature T1 (500℃), the target temperature T2 (1000℃), and the desired heating rate Vt (e.g., 1℃ / min) (steps S40-S41). This is, for example, set manually by the operator.

[0241] Next, the desired displacement velocity is calculated (step S42). This is performed, for example, by the first displacement velocity calculation unit 208. Specifically, when the temperature of the reaction vessel 100 (intermediate part A3) is controlled to change from the current temperature T1 to the target temperature T2 at a desired cooling rate Vt, the first displacement velocity calculation unit 208 calculates the displacement velocity (desired displacement velocity V1) of point E of the reaction vessel 100. At this time, the first displacement velocity calculation unit 208 calculates, for example, taking into account the desired heating rate Vt, material properties (e.g., the coefficients of thermal expansion of each component forming the reaction vessel 100), etc. This desired displacement velocity V1 (calculated value) can be obtained, for example, by... Figure 25 The straight line C5 in the diagram represents this. Figure 25 This is a graph showing the relationship between the desired displacement velocity V1 and the actual displacement velocity V2 of point E when the reaction vessel 100 is subjected to temperature control (heating control).

[0242] Next, the position of point E is measured and the actual displacement velocity V2 (measured value) is calculated (step S43). This is performed by the second displacement velocity calculation unit 209. Specifically, the second displacement velocity calculation unit 209 calculates the actual displacement velocity V2 of point E based on the actual position of point E (a specific location) measured by the position measuring device 260 (multiple positions measured at different times). The actual displacement velocity V2 (measured value) of point E can be calculated, for example, by... Figure 25 Curve C6 in the figure represents this.

[0243] Next, a heating rate control process is performed (step S44). This heating rate control process is used to control the heating rate of the reaction vessel 100 (intermediate part A3) so that the actual displacement velocity V2 of point E calculated in step S43 follows (matches) the desired displacement velocity V1 of point E calculated in step S42, and this process is implemented by the temperature control unit 202.

[0244] Reference Figure 26 The heating rate control process (step S44) will be described in detail. Figure 26 This is a flowchart of the heating rate control process.

[0245] like Figure 26 As shown, firstly, it is determined whether the actual displacement velocity V2 and the desired displacement velocity V1 deviate from each other (for example, whether the difference between the actual displacement velocity V2 and the desired displacement velocity V1 exceeds a threshold) (step S441). This is determined, for example, by the temperature control unit 202 comparing the actual displacement velocity V2 of point E calculated in step S43 with the desired displacement velocity V1 of point E calculated in step S42.

[0246] As a result, when the actual displacement velocity V2 and the desired displacement velocity V1 deviate from each other (step S441: yes) and this deviation is a positive deviation (refer to...) Figure 25 When arrow AR10 is displayed (step S442: Yes), this means that the actual displacement velocity V2 of point E is slower than the desired displacement velocity V1 of point E. In this case, the heating rate of the reaction vessel 100 (upper A, lower C, left D, and right B) is increased (step S443). For example, the temperature control unit 202 increases the heating rate from 1°C / min to 2°C / min. Specifically, the temperature control unit 202 controls each heater so that the actual displacement velocity V2 of point E follows (matches) the desired displacement velocity V1 of point E. Therefore, the actual displacement velocity V2 of point E follows the desired displacement velocity V1 of point E (refer to...). Figure 25 ).

[0247] On the other hand, when the actual displacement velocity V2 and the desired displacement velocity V1 deviate from each other (step S441: yes) and this deviation is a negative deviation (refer to...) Figure 25When arrow AR11 is visible (step S442: No), this means that the actual displacement velocity V2 of point E is faster than the desired displacement velocity V1 of point E. In this case, the heating rate of the reaction vessel 100 (upper A, lower C, left D, and right B) is reduced (step S444). For example, the temperature control unit 202 reduces the heating rate from 2°C / min to 1°C / min. Specifically, the temperature control unit 202 controls each heater so that the actual displacement velocity V2 of point E follows (matches) the desired displacement velocity V1 of point E. Therefore, the actual displacement velocity V2 of point E follows the desired displacement velocity V1 of point E (refer to...). Figure 25 ).

[0248] When the actual displacement velocity V2 and the desired displacement velocity V1 are not deviated from each other (step S441: No), the processing after step S441 is not performed.

[0249] Repeat the above processes in steps S43 and S44 until the temperature of the reaction vessel 100 reaches the target temperature T2 set in step S40 (step S45: no).

[0250] Example 2: When the temperature of the reaction vessel 100 has reached the target temperature (step S45: Yes), the operation of the reaction apparatus 10A is terminated.

[0251] As described above, according to the operating example 2 of the reaction apparatus 10A, the actual displacement velocity V2 of point E follows the desired displacement velocity V1 of point E until the temperature of the reaction vessel 100 reaches the target temperature T2 (refer to...). Figure 25 ).

[0252] <Third question (problem when temperature control (heating control) is applied to reaction vessel 100)>

[0253] like Figure 26 As shown, when the reaction vessel 100 is heated (heating control), the following situation may occur: even if the heating rate of the reaction vessel 100 (upper part A, lower part C, left part D and right part B) is increased (step S443), point E still does not move, that is, the actual displacement rate V2 (measured value) of point E does not follow the expected displacement rate V1 (calculated value) of point E.

[0254] In this situation, for example, due to the contact between the reaction vessel 100 and the conveying mechanism 120, there may be a malfunction in the second support 104, which serves as a movable support (the third problem). Figure 25 The shaded area in the diagram shows a hazardous area where the reaction vessel 100 may come into contact with the conveyor mechanism 120.

[0255] <Second Implementation Method>

[0256] Subsequently, as a second embodiment, a construction example 1 for solving the aforementioned third problem will be described. In the following text, the reaction apparatus according to the second embodiment will be referred to as reaction apparatus 10B.

[0257] Figure 27 This is a block diagram of the reaction apparatus 10B according to the second embodiment.

[0258] like Figure 27 As shown, the reaction apparatus 10B of the second embodiment corresponds to the reaction apparatus 10A of the first embodiment formed by adding an emergency operation control unit 290. Hereinafter, components with the same configuration as the reaction apparatus 10A of the first embodiment described above will be labeled with the same reference numerals, and descriptions thereof will be omitted as appropriate.

[0259] Emergency operation control unit 290 performs emergency procedures (emergency operation) to prevent the reaction apparatus 10B from becoming unable to operate normally. Emergency procedures may include, for example, procedures to control each heater to reduce the heating rate of the reaction vessel 100, procedures to stop the heating in the reaction vessel 100 (performing an emergency stop to the heating in the reaction vessel 100), or other procedures.

[0260] The process for stopping (performing an emergency stop) the heating in the reaction vessel 100 can be similar to a thermal stop process (for example, stopping the power supply to the temperature control unit 202), which is performed when the emergency stop button (not shown) provided on the reaction apparatus 10B is pressed.

[0261] Furthermore, an example of emergency handling could be a process for notifying the user of information indicating that an anomaly has occurred in the reaction device 10B. This notification process could be, for example, displaying the information indicating that an anomaly has occurred in the reaction device 10B on a display device (e.g., a monitor), or outputting an audio message indicating that an anomaly has occurred in the reaction device 10B from an audio output device (e.g., a speaker).

[0262] <Example 1 of Emergency Handling>

[0263] Subsequently, referring to Figure 28 The following will provide a detailed explanation of Emergency Response Example 1.

[0264] Figure 28 This is a flowchart of Emergency Response Example 1. Emergency Response Example 1 is executed in step S443 (refer to...). Figure 26 ).

[0265] First, the position of point E is determined (step S4431). This is performed by the position determining device 260.

[0266] Next, it is determined whether the time change dx / dt of the position of point E measured in step S4431 becomes negative (step S4432). When the time change dx / dt of the position of point E becomes negative (step S4432: yes), this means that with the heating of the reaction vessel 100, the position of point E is on the long axis AX. 100 If the displacement is correct in the direction, in this case, the process moves to step S4431 without performing emergency processing (emergency run), and then repeats the subsequent processing.

[0267] On the other hand, when the time change dx / dt of the position of point E does not become negative (step S4432: No), this means that there exists a point E whose position is not on the major axis AX. 100 The possibility of correct displacement in the direction, that is, the possibility that the second support 104, which is a movable support, may not be operating normally (for example, the possibility that the reaction vessel 100 may come into contact with the conveying mechanism 120), in which case an emergency procedure (emergency operation) is performed (step S4433). This is implemented by the emergency operation control unit 290. This emergency procedure may be, for example, a procedure to control the individual heaters to reduce the heating rate of the reaction vessel 100, a procedure to stop (perform an emergency stop) the heating in the reaction vessel 100, or other procedures. Therefore, the above-mentioned problem 3 is solved.

[0268] <Emergency Response Example 2>

[0269] Next, we will explain an example of emergency handling, Example 2.

[0270] The difference between Emergency Handling Example 1 and Emergency Handling Example 2 is that in Emergency Handling Example 1, the time change of the position of point E after increasing the heating rate is used as the reference for the transition to Emergency Handling (Emergency Operation), while in Emergency Handling Example 2, the degree of deviation from "ideal expansion" is used as the reference for the transition to Emergency Handling (Emergency Operation).

[0271] In other words, even when the second support 104, which serves as a movable support, is functioning normally, the position of point E may not change immediately after the heating rate is increased.

[0272] To address the aforementioned issues, in Emergency Handling Example 2, a threshold is pre-set to allow the deviation between the desired displacement velocity V2 and the actual displacement velocity V1. When the deviation between the desired displacement velocity V2 and the actual displacement velocity V1 exceeds the aforementioned threshold, the operation is moved to emergency mode.

[0273] Next, refer to Figure 29 Example 2 of emergency handling will be explained in detail.

[0274] Figure 29 This is a flowchart of Emergency Response Example 2. In step S443 (refer to...) Figure 26 Example 2 of performing emergency handling in )

[0275] First, the position of point E is determined and the actual displacement velocity V2 is calculated (step S4434). This is performed by the second displacement velocity calculation unit 209. Specifically, the second displacement velocity calculation unit 209 calculates the actual displacement velocity V2 of point E (a specific location) based on the actual position of point E (a specific location) measured by the position measuring device 260 (multiple positions measured at different times).

[0276] Next, when the deviation between the desired displacement velocity V1 and the actual displacement velocity V2 does not exceed the threshold (step S4435: No), this means that, according to the increase in the heating rate, the position of point E is on the major axis AX. 100 If the displacement is correct in the direction, in this case, the process moves to step S4434 without performing emergency processing (emergency run), and then repeats the subsequent processing.

[0277] On the other hand, when the deviation between the desired displacement velocity V1 and the actual displacement velocity V2 exceeds the threshold (step S4435: Yes), it means that although the heating rate has been increased, the position of point E is not on the major axis AX. 100 If the displacement is correct in the direction, that is, there is a possibility that the second support 104, which is a movable support, may not operate normally (for example, there is a possibility that the reaction vessel 100 may come into contact with the conveying mechanism 120). In this case, an emergency operation (emergency operation) is performed (step S4436). This is implemented by the emergency operation control unit 290. The emergency operation may be, for example, a process for controlling the individual heaters to reduce the heating rate of the reaction vessel 100, a process for stopping (performing an emergency stop) the heating in the reaction vessel 100, or other processes. Therefore, the above-mentioned problem 3 is solved.

[0278] <Emergency Response Example 3>

[0279] Next, we will describe an example of emergency handling, example 3.

[0280] Emergency handling example 3 is equivalent to the emergency handling example 2 above (refer to...). Figure 29 The situation formed by adding step S4437 in )

[0281] The difference between Emergency Handling Example 1 and Emergency Handling Example 3 is that in Emergency Handling Example 1, the time change of the position of point E after the heating rate increases is used as the reference for the transition to emergency handling, while in Emergency Handling Example 3, "behavior different from behavior in steady state" is used as the reference for the transition to emergency handling.

[0282] In actual production operation, heating and cooling are performed in the same pattern each time. In Emergency Handling Example 3, a threshold is preset to allow deviations from "behavior different from behavior in steady state", and when the deviation exceeds the threshold, the operation is moved to emergency operation.

[0283] Next, refer to Figure 30 Example 3 of emergency handling will be explained in detail.

[0284] Figure 30 This is the flowchart for Example 3 in an emergency. In step S443 (refer to...) Figure 26 Example 3 is executed in emergency situations.

[0285] First, the position of point E is determined and the actual displacement velocity V2 is calculated (step S4434). This is performed by the second displacement velocity calculation unit 209. Specifically, the second displacement velocity calculation unit 209 calculates the actual displacement velocity V2 of point E (a specific location) based on the actual position of point E (a specific location) measured by the position measuring device 260 (multiple positions measured at different times).

[0286] Next, when the deviation between the desired displacement velocity V1 and the actual displacement velocity V2 does not exceed the threshold (step S4435: No) and the deviation between the desired displacement velocity V1 and the actual displacement velocity V2 does not exceed the threshold in the steady state (step S4437: No), this means that, with the increase of the heating rate, the position of point E on the major axis AX... 100 If the displacement is correct in the direction, in this case, emergency handling (emergency run) is not performed, but the process proceeds to step S4434, and then the subsequent processing is repeated.

[0287] On the other hand, when the deviation between the desired displacement velocity V1 and the actual displacement velocity V2 exceeds the threshold (step S4435: Yes), or when the deviation between the desired displacement velocity V1 and the actual displacement velocity V2 exceeds the threshold in the steady state (step S4437: Yes), this means that although the heating rate has increased, the position of point E is not on the major axis AX. 100 If the displacement is correct in the direction, that is, there is a possibility that the second support 104, which is a movable support, may not operate normally (for example, there is a possibility that the reaction vessel 100 may come into contact with the conveying mechanism 120). In this case, an emergency operation (emergency operation) is performed (step S4436). This is implemented by the emergency operation control unit 290. The emergency operation may be, for example, a process for controlling the individual heaters to reduce the heating rate of the reaction vessel 100, a process for stopping (performing an emergency stop) the heating in the reaction vessel 100, or other processes. Therefore, the above-mentioned problem 3 is solved.

[0288] <Third Implementation Method>

[0289] Next, as a third embodiment, a construction example 2 for solving the second problem described above will be described. In the following text, the reaction apparatus according to the third embodiment will be referred to as reaction apparatus 10C.

[0290] Figure 31 This is a block diagram of the reaction apparatus 10C according to the third embodiment.

[0291] like Figure 31 As shown, the reaction apparatus 10C in the third embodiment corresponds to the reaction apparatus 10A of the first embodiment formed by adding a temperature control mode correction unit 291. Hereinafter, components with the same configuration as the reaction apparatus 10A of the first embodiment will be labeled with the same reference numerals, and descriptions thereof will be omitted as appropriate.

[0292] In the reaction apparatus 10C of the third embodiment, such as Figure 32 As shown, a temperature control table is stored in the storage section 207. Figure 32 An example of a temperature control table stored in storage unit 207 is shown. Storage unit 207 shows an example of a temperature control mode storage unit and a displacement speed storage unit according to this disclosure.

[0293] like Figure 32 As shown, the temperature control table includes the following items: current temperature DT1, target temperature DT2, desired cooling rate DT3, desired displacement rate DT4, and temperature control mode DT5.

[0294] The current temperature of the reaction vessel 100 is stored as the current temperature DT1. The target temperature of the reaction vessel 100 is stored as the target temperature DT2. The cooling rate (or heating rate) set considering the above-mentioned <desired temperature conditions> is stored as the desired cooling rate (or heating rate) DT3. The displacement rate (desired displacement rate V1) calculated by the first displacement rate calculation unit 208 is stored as the desired displacement rate DT4. Until the temperature of the reaction vessel 100 (intermediate part A3) reaches the target temperature DT2 from the current temperature DT1, the control mode of each heater actually controlled by the temperature control unit 202 (for example, information about the current value energized to each heater in each time period) is stored as the temperature control mode DT5.

[0295] The temperature control mode correction unit 291 corrects the temperature control mode DT5 in a way that makes the displacement speed (V1 or V2) of point E (a specific location) of the reaction vessel 100 as fast as possible. For example, the temperature control unit 202 stores multiple control modes of each heater until the temperature of the reaction vessel 100 (intermediate part A3) reaches the target temperature DT2 from the current temperature DT1. Then, the temperature control mode correction unit 291 stores (rewrites) the temperature control mode in the storage unit 207 (temperature control mode DT5) that makes the displacement speed (V1 or V2) the fastest among the stored temperature control modes (multiple times).

[0296] Alternatively, the temperature control mode correction unit 291 can correct the temperature control mode DT5 based on the results of machine learning, in a way that maximizes the displacement velocity (V1 or V2) of point E (a specific location) of the reaction vessel 100. For example, a learning model can be generated by a learning engine (e.g., scikit-learn), and the temperature control mode that maximizes the displacement velocity (VE or DT4) can be predicted (estimated) by the learning model. The predicted temperature control mode can be stored (rewritten) in the storage unit 207 (temperature control mode DT5). For example, the temperature control mode correction unit 291 can be implemented by executing a predetermined program by the control device 200. The temperature control mode correction unit 291 is not limited to being implemented by a predetermined program, and can also be implemented by hardware.

[0297] The correction performed by the temperature control mode correction unit 291 can be manually performed based on experience. For example, the temperature control mode can be corrected based on experience to make the displacement speed (V1 or V2) of point E (specific location) of the reaction vessel 100 as fast as possible, and the corrected temperature control mode can be stored (rewritten) in the storage unit 207 (temperature control mode DT5).

[0298] <Example 1 of the operation of reaction device 10C>

[0299] Next, refer to Figure 33 Example 1 of the operation of reaction apparatus 10C will be described.

[0300] Figure 33 This is a flowchart of an example 1 of the operation of the reaction apparatus 10C.

[0301] Operating Example 1 of the reaction apparatus 10C corresponds to Operating Example 1 of the above-described reaction apparatus 10A (refer to...) Figure 22 Example 1 is formed by adding steps S31A, S32A, S32B and S36-S39.

[0302] The following is an example of the operation of the reaction apparatus 10C, illustrating the operation example of controlling the temperature of the reaction vessel 100 from the current temperature of 1000°C to the target temperature of 500°C (cooling control).

[0303] First, set the current temperature T1 (1000℃), the target temperature T2 (500℃), and the desired cooling rate Vt (e.g., 1℃ / min) (steps S30-S31). This is, for example, set manually by the operator.

[0304] Next, when no stored setting value exists (step S31A: No), that is, when the temperature control mode corresponding to the current temperature T1 and the target temperature T2 is not stored in the storage unit 207 (temperature control mode DT5), the desired displacement velocity V1 is calculated (step S32). This is performed, for example, by the first displacement velocity calculation unit 208. Specifically, when the temperature of the reaction vessel 100 (intermediate part A3) changes from the current temperature T1 to the target temperature T2 at a desired cooling rate Vt, the first displacement velocity calculation unit 208 calculates the displacement velocity (desired displacement velocity V1) of point E of the reaction vessel 100. At this time, the first displacement velocity calculation unit 208 calculates the desired cooling rate Vt, for example, by considering material properties (e.g., the coefficients of thermal expansion of each component forming the reaction vessel 100). This desired displacement velocity V1 (calculated value) can be obtained, for example, by... Figure 21 The line C3 in the diagram represents this.

[0305] Next, the desired displacement velocity V1 calculated in step S32 is stored (step S32A). Specifically, the desired displacement velocity V1 calculated in step S32 is stored in storage unit 207 (desired displacement velocity DT4) so ​​that it is associated with the current temperature DT1, the target temperature DT2, and the desired cooling rate DT3. Note that the current temperature T1 and target temperature T2 set in step S30 and the desired cooling rate Vt set in step S31 are stored as the current temperature DT1, the target temperature DT2, and the desired cooling rate DT3.

[0306] Next, the position of point E is measured and the actual displacement velocity V2 (measured value) is calculated (step S33). This is performed by the second displacement velocity calculation unit 209. Specifically, the second displacement velocity calculation unit 209 calculates the actual displacement velocity V2 of point E based on the actual position of point E (a specific location) measured by the position measuring device 260 (multiple positions measured at different times). The actual displacement velocity V2 (measured value) of point E can be calculated, for example, by... Figure 21 Curve C4 in the figure represents this.

[0307] Next, a cooling rate control process is performed (step S34). This cooling rate control process is used to control the cooling rate of the reaction vessel 100 (intermediate part A3) so that the actual displacement velocity V2 of point E calculated in step S33 follows (matches) the desired displacement velocity V1 of point E calculated in step S32, and this process is implemented by the temperature control unit 202. As described above in the operating example 1 of the reaction apparatus 10A (refer to...) Figure 23 The cooling rate control process has already been explained in the document, so its description will be omitted.

[0308] Repeat steps S33 and S34 above until the temperature of the reaction vessel 100 reaches the target temperature T2 set in step S30 (step S35: No).

[0309] Next, when the temperature of the reaction vessel 100 reaches the target temperature T2 (step S35: Yes) and the temperature control mode has not yet been stored in the storage unit 207 (temperature control mode DT5) (step S36: No), the temperature control mode is stored in the storage unit 207 (temperature control mode DT5) (step S37). The temperature control mode stored here is the control mode of each heater that the temperature control unit 202 has actually controlled until the temperature of the reaction vessel 100 (intermediate part A3) reaches the target temperature T2 from the current temperature T1 in step S34, for example, information about the current value flowing through each heater in each time period. This temperature control mode is stored in the storage unit 207 (temperature control mode DT5) so that it is associated with the current temperature DT1, the target temperature DT2, and the desired cooling rate DT3.

[0310] Next, it is determined whether temperature control has been properly performed (step S38). This is achieved, for example, by the control device 200 executing a predetermined program.

[0311] As a result, when it is determined that the temperature control has been properly performed (step S38: yes), the operation of the reaction apparatus 10C Example 1 is terminated.

[0312] On the other hand, when it is determined that the temperature control is not properly performed (step S38: No), the heater control conditions (the temperature control mode stored in step S37) are corrected and rewritten (step S39), and the operation of the reaction apparatus 10C Example 1 is terminated. This correction is performed by the temperature control mode correction unit 291. Specifically, the temperature control mode correction unit 291 corrects the temperature control mode DT5 in a way that makes the displacement speed (V1 or V2) of point E (specific location) of the reaction vessel 100 as fast as possible. For example, the control modes of each heater actually controlled by the temperature control unit 202 until the temperature of the reaction vessel 100 (intermediate part A3) reaches the target temperature DT2 position from the current temperature DT1 are stored in the storage unit 207, etc. Then, the temperature control mode correction unit 291 stores (rewrites) the temperature control mode that makes the displacement speed (V1 or V2) the fastest among the stored temperature control modes in the storage unit 207 (temperature control mode DT5). Note that the processing in steps S38 and S39 can be performed manually based on experience.

[0313] As described above, according to the operating example 1 of the reaction apparatus 10C, the actual displacement velocity V2 of point E follows the desired displacement velocity V1 of point E until the temperature of the reaction vessel 100 reaches the target temperature T2 (refer to...). Figure 21 Therefore, the second problem mentioned above has been solved.

[0314] Furthermore, according to the operating example 1 of the reaction apparatus 10C, storing the temperature control mode in step S37 brings the following advantages.

[0315] That is, by storing the temperature control mode in step S37, when the same current temperature T1 and the same target temperature T2 as the previous step are set in the next step S30, and the same expected cooling rate Vt as the previous step is set in step S31, it is determined in step S31A that there are stored settings (step S31A: Yes). That is, the expected displacement speed and temperature control mode corresponding to the current temperature T1 and target temperature T2 set in step S30 and the expected cooling rate Vt set in step S31 are stored in the storage unit 207 (expected displacement speed DT4, temperature control mode DT5), and the expected displacement speed and temperature control mode are read from the storage unit 207 (expected displacement speed DT4, temperature control mode DT5) (step S32B) and used in subsequent processing. Therefore, it has the advantage that the processing in steps S32 and S32A can be omitted.

[0316] Furthermore, by performing the processes in steps S37-S39, the following advantages are obtained. That is, even when a desired displacement speed and temperature control pattern based on past experience has already been read from storage unit 207, the actual displacement speed in the currently executed pattern may not be exactly the same as in the past. Therefore, when a desired displacement speed and temperature control pattern based on past experience has been executed, both the past and current displacement speeds are stored in storage unit 207 (step S37). When a difference exists between them, the operator determines whether the difference is permissible. If the difference is not permissible, the operator appropriately adjusts the control conditions (heater control conditions) and further stores (rewrites) the results in storage unit 207 (step S39). Therefore, there is an advantage that storage unit 207 acquires new data for machine learning, and by comparing this new data with past data, the new data can be used for calculations to find patterns in the temperature control pattern.

[0317] <Example 2 of the operation of reaction device 10C>

[0318] Next, refer to Figure 34 Example 2 of the operation of the reaction apparatus 10C will be described. Example 1 of the operation of the reaction apparatus 10C is an example of the cooling control of the reaction vessel 100, while Example 2 of the operation of the reaction apparatus 10C is an example of the heating control of the reaction vessel 100.

[0319] Figure 34 This is a flowchart of an example 2 of the operation of reaction apparatus 10C.

[0320] The following is an example of operation of the reaction apparatus 10C, illustrating the operation example of controlling the temperature of the reaction vessel 100 from the current temperature of 500°C to the target temperature of 1000°C (heating control).

[0321] First, set the current temperature T1 (500℃), the target temperature T2 (1000℃), and the desired cooling rate Vt (e.g., 1℃ / min) (steps S40-S41). This is, for example, set manually by the operator.

[0322] Next, when no stored setting value exists (step S41A: No), that is, when the temperature control mode corresponding to the current temperature T1 and the target temperature T2 is not stored in the storage unit 207 (temperature control mode DT5), the desired displacement velocity V1 is calculated (step S42). This is performed, for example, by the first displacement velocity calculation unit 208. Specifically, when the temperature of the reaction vessel 100 (intermediate part A3) changes from the current temperature T1 to the target temperature T2 at a desired cooling rate Vt, the first displacement velocity calculation unit 208 calculates the displacement velocity (desired displacement velocity V1) of point E of the reaction vessel 100. At this time, the first displacement velocity calculation unit 208 calculates the desired cooling rate Vt, for example, by considering material properties (e.g., the coefficient of thermal expansion of each component forming the reaction vessel 100). This desired displacement velocity V1 (calculated value) can be obtained, for example, by... Figure 25 The straight line C5 in the diagram represents this.

[0323] Next, the desired displacement velocity V1 calculated in step S42 is stored (step S42A). Specifically, the desired displacement velocity V1 calculated in step S42 is stored in storage unit 207 (desired displacement velocity DT4) so ​​that it is associated with the current temperature DT1, the target temperature DT2, and the desired cooling rate DT3. The current temperature T1 and target temperature T2 set in step S40 and the desired cooling rate Vt set in step S31 are stored as the current temperature DT1, the target temperature DT2, and the desired cooling rate DT3.

[0324] Next, the position of point E is measured and the actual displacement velocity V2 (measured value) is calculated (step S43). This is performed by the second displacement velocity calculation unit 209. Specifically, the second displacement velocity calculation unit 209 calculates the actual displacement velocity V2 of point E based on the actual position of point E (a specific location) measured by the position measuring device 260 (multiple positions measured at different times). The actual displacement velocity V2 (measured value) of point E can be calculated, for example, by... Figure 25 Curve C6 in the figure represents this.

[0325] Subsequently, a heating rate control process is performed (step S44). This heating rate control process is used to control the heating rate of the reaction vessel 100 (intermediate part A3) so that the actual displacement velocity V2 of point E calculated in step S43 follows (matches) the desired displacement velocity V1 of point E calculated in step S42, and this process is implemented by the temperature control unit 202. As described above in the operating example 2 of the reaction apparatus 10A (refer to...) Figure 26 The heating rate control process has already been explained in the document, so its description will be omitted.

[0326] Repeat steps S43 and S44 above until the temperature of the reaction vessel 100 reaches the target temperature T2 set in step S40 (step S45: No).

[0327] Next, when the temperature of the reaction vessel 100 reaches the target temperature T2 (step S45: Yes) and the temperature control mode has not yet been stored in the storage unit 207 (temperature control mode DT5) (step S46: No), the temperature control mode is stored in the storage unit 207 (temperature control mode DT5) (step S47). The temperature control mode stored here is the control mode of each heater actually controlled by the temperature control unit 202 until the temperature of the reaction vessel 100 (intermediate part A3) reaches the target temperature T2 from the current temperature T1 in step S44. For example, information about the current value flowing through each heater in each time period. This temperature control mode is stored in the storage unit 207 (temperature control mode DT5) so that it is associated with the current temperature DT1, the target temperature DT2, and the desired cooling rate DT3.

[0328] Next, it is determined whether temperature control has been properly performed (step S48). This is achieved, for example, by the control device 200 executing a predetermined program.

[0329] As a result, when it is determined that the temperature control has been properly performed (step S48: yes), the operation of the reaction apparatus 10C is terminated, Example 2.

[0330] On the other hand, when it is determined that the temperature control is not properly performed (step S48: No), the heater control conditions are corrected and rewritten (the temperature control mode stored in step S47) (step S49), and the operation of the reaction apparatus 10C Example 2 is terminated. This correction is performed by the temperature control mode correction unit 291. Specifically, the temperature control mode correction unit 291 corrects the temperature control mode DT5 in a way that makes the displacement speed (V1 or V2) of point E (specific part) of the reaction vessel 100 as fast as possible. For example, the control modes (multiple times) of each heater actually controlled by the temperature control unit 202 until the temperature of the reaction vessel 100 (intermediate part A3) reaches the target temperature DT2 from the current temperature DT1 are stored in the storage unit 207, etc. Then, the temperature control mode correction unit 291 stores (rewrites) the temperature control mode (multiple times) in which the displacement speed (V1 or V2) becomes the fastest in the stored temperature control modes (multiple times) into the storage unit 207 (temperature control mode DT5). Note that the processing in steps S48 and S49 can be performed manually based on experience.

[0331] As described above, according to the operating example 2 of the reaction apparatus 10C, the actual displacement velocity V2 of point E follows the desired displacement velocity V1 of point E until the temperature of the reaction vessel 100 reaches the target temperature T2 (refer to...). Figure 25).

[0332] Furthermore, according to the operating example 2 of the reaction apparatus 10C, storing the temperature control mode in step S37 brings the following advantages.

[0333] That is, by storing the temperature control mode in step S47, when the current temperature T1 and the target temperature T2 are set to be the same as the previous time in step S40, and the expected heating rate Vt is set to be the same as the previous time in step S41, it is determined in step S41A that there are stored settings (step S41A: Yes). That is, the expected displacement speed and temperature control mode corresponding to the current temperature T1 and target temperature T2 set in step S40 and the expected heating rate Vt set in step S31 are stored in the storage unit 207 (expected displacement speed DT4, temperature control mode DT5), and the expected displacement speed and temperature control mode are read from the storage unit 207 (expected displacement speed DT4, temperature control mode DT5) (step S42B) and used for subsequent processing. Therefore, it has the advantage that the processing in steps S42 and S42A can be omitted.

[0334] Furthermore, by performing the processes in steps S47-S49, the following advantages are obtained. That is, even when a desired displacement speed and temperature control pattern based on past experience has already been read from storage unit 207, the actual displacement speed in the currently executed pattern may not be exactly the same as in the past. Therefore, when a desired displacement speed and temperature control pattern based on past experience has been executed, both the past and current displacement speeds are stored in storage unit 207 (step S47). When a difference exists between them, it is determined whether the operator can tolerate the difference. If the difference cannot be tolerated, the operator appropriately adjusts the control conditions (heater control conditions) and further stores (rewrites) the results in storage unit 207 (step S49). Therefore, there is an advantage that storage unit 207 acquires new data for machine learning and compares this new data with past data; this new data can be used for calculations to find patterns in the temperature control pattern.

[0335] In the operating example 2 of the reaction apparatus 10C, the above-described <Emergency Handling Example 1> to <Emergency Handling Example 3> can also be applied. Therefore, in the operating example 2 of the reaction apparatus 10C, the above-described problem 3 is also solved.

[0336] Although the invention has been specifically described with reference to the embodiments, it is undeniable that the invention is not limited to the described embodiments and various modifications can be made without departing from the spirit of the invention.

[0337] This application is based on and claims priority to Japanese Patent Application JP 2023-048316, filed on March 24, 2023, the disclosure of which is incorporated herein by reference in its entirety.
