[0028] Hereinafter, the present invention will be described by way of embodiments of the present invention. However, the present invention according to the scope of the claims is not limited to the following embodiments. Not all components described in the embodiments are essential means for solving the problems. For the sake of clarity, the following description and drawings are appropriately omitted or simplified. In each drawing, the same reference numerals are given to the same elements, and repeated descriptions are omitted as appropriate.

[0029] <First Embodiment (Reference Example)>

[0030] Reference Figure 1 , the main components of the reaction apparatus according to the first embodiment (reference example) will be described. Figure 1 Is a side view of the reaction apparatus 10 according to the first embodiment. Figure 1 Shows a state in which the reaction apparatus 10 is partially cut away for easy understanding.

[0031] The reaction apparatus 10 is, for example, an apparatus for manufacturing a product by applying conditions, such as a predetermined physical stimulus, to a powdery or granular object to be processed. The reaction apparatus 10 includes a cylindrical reaction vessel 100 (reaction furnace), a supply unit (supply port 101) for supplying the object to be processed R10 to the reaction vessel 100, a discharge unit (discharge port 102) for discharging the product from the reaction vessel 100, a transport mechanism 120 (such as a screw) for transporting the object to be processed R10 supplied to the reaction vessel 100 from the supply unit of the reaction vessel 100 to the discharge unit of the reaction vessel 100, a fluid supply unit (first fluid inlet 131, first fluid outlet 132, first valve 134, etc.) for supplying a fluid that contacts the transported object to be processed into the reaction vessel 100, and a temperature control unit (temperature control region 110, etc.) for controlling the temperature of the reaction vessel 100 for each of different regions in the direction of the long axis AX 100 of the reaction vessel 100.

[0032] The physical stimulus is not particularly limited as long as it is a means used in the process of converting the object to be processed into a product. Examples of the physical stimulus include temperature changes, such as heating and cooling. Examples of the physical stimulus include stress transfer, such as stirring, mixing, kneading, and pulverizing. The physical stimulus is, for example, a reaction that receives electrons or free radicals.

[0033] In the reaction apparatus 10, the object to be processed R10 supplied to the reaction vessel 100 is heated while being transported toward the discharge port of the reaction vessel 100 by the transport mechanism 120, and a predetermined fluid that contacts the transported object to be processed R10 is supplied into the reaction vessel 100, whereby the object to be processed R10 (object to be processed) is continuously processed at a predetermined temperature. The object to be processed may be a solid, a fluid, or a mixture thereof. In order to enable, for example, stirring of the object to be processed while transporting, the reaction vessel 100 itself may be rotatable, or a transport mechanism 120 having a rotatable structure may be provided in the reaction vessel 100.

[0034] Although the types and states of the object to be processed and the product are not particularly limited, the object to be processed and the product may be inorganic substances containing lithium as one of the components, such as metal oxides or metal sulfides, or may be organic substances, such as hydrocarbons or foods. The object to be processed may be a solid, such as a powdery or granular material, or may be a fluid, such as a liquid or a gas.

[0035] In the process of conversion into a product, the object to be treated can be converted into a product via an intermediate. The form or state of the intermediate is not particularly limited. In the case of performing two or more reactions in a stepwise manner, the intermediate may be, for example, the product of each reaction. In this case, the intermediate is, for example, an anhydrous compound produced by heating a hydrated compound. Alternatively, the intermediate may be a monosaccharide produced by hydrolysis of a polysaccharide. The intermediate may be a sintered body in which at least a portion of the object to be treated has been grain-grown or sintered. The intermediate may be in a state in which at least a portion of the object to be treated has been liquefied or gasified. The intermediate may be in a state in which the temperature, hardness, etc. of the object to be treated have changed, even if its appearance has not changed. The intermediate may be in a form or state other than the above.

[0036] The type or state of the product is not particularly limited, and the product may be a solid, such as a powdery material, or may be a fluid, such as a liquid or a gas. Alternatively, the product may be a mixture containing a material different from the object to be processed, such as a catalyst or a transport auxiliary material. The product may be a mixture containing two or more compounds, such as a main product and a byproduct.

[0037] The shape and size of each of the object to be processed and the product are not particularly limited. When the object to be processed and the product are each a powdery material, the particle size is preferably 50 mm or less, more preferably 0.005-20 mm. When the object to be processed and the product have a block shape, the ratio of the diagonal length (aspect ratio) is preferably 1-10, more preferably 1.3-1.8.

[0038] The reaction device 10 includes a reaction container 100 , a temperature control region 110 , a conveying mechanism 120 , a first fluid control region 130 , and a second fluid control region 140 as main components.

[0039] The reaction vessel 100, for example, has a cylindrical shape and includes a supply port 101 for receiving an object to be processed and a delivery port 102 for delivering a product. The supply port 101 is an example of a supply unit disclosed herein. Note that the shape and configuration of the reaction vessel 100 are not particularly limited. The cross-sectional shape of the reaction vessel 100, for example, may be circular or elliptical, polygonal (such as a quadrilateral shape) or other shapes. For example, the reaction vessel 100 may be formed by one component, or more than two components may be coupled to each other. If more than two components are coupled to each other, a fastening mechanism, such as a bolt, for example, may be used in a place where the components are coupled to each other.

[0040] The reaction vessel 100 includes an intermediate portion A3 between a supply port 101 and a discharge port 102. The number of the supply ports 101, the number of the discharge ports 102, the number of the intermediate portions A3, and their arrangements are not particularly limited. For example, two or more supply ports 101 and two or more discharge ports 102 may be respectively provided at both ends of the intermediate portion A3.

[0041] Alternatively, the supply port 101 may be located in the middle of the reaction vessel 100, and the intermediate portion A3 and the discharge port 102 are respectively included at both ends of the supply port 101. In this case, the object to be treated R10 can be supplied to the middle of the reaction vessel 100, and the product R11 can be respectively discharged from each of one end side and the other end side 100 of the reaction vessel. Further, in this case, a screw can be used as the conveying mechanism 120, for example, and the orientation (helical orientation) of the convex portions having a helical shape on the screw can be reversed before and after (with the supply port 101 as the boundary) the supply port 101, whereby the object to be treated R10 can be branched and conveyed to one end side and the other end side of the reaction vessel 100 with the supply port 101 as the boundary. Or, if the discharge port 102 is located in the middle of the reaction vessel 100, and the intermediate portion A3 and the supply port 101 are respectively provided at both ends of the discharge port 102, a screw can be used as the conveying mechanism 120, for example, and the orientation (helical orientation) of the convex portions having a helical shape on the screw can be reversed before and after (with the discharge port 102 as the boundary) the discharge port 102, whereby the product R11 can be conveyed such that the product R11 is assembled from one end side and the other end side of the reaction vessel 100 with the discharge port 102 as the boundary. In this way, for example, in the case where a plurality of reaction apparatuses 10 are coupled in parallel to each other, a mechanism for conveying the object to be treated R10, the product R11, etc. in a manner of branching or assembling the object to be treated R10, the product R11, etc. is preferable.

[0042] The reaction vessel 100 is formed of a material capable of allowing a temperature change generated when producing a product in a furnace and allowing contact with a substance (object to be treated, etc.) supplied to the furnace or a substance to be produced (product, etc.). The reaction vessel 100 and the conveying mechanism 120 can be formed of an alloy, ceramics, carbon, or a composite material containing two or more of the above, for example. An alloy is a metal material containing at least one of alloying elements including nickel, cobalt, chromium, molybdenum, tungsten, tantalum, titanium, iron, copper, aluminum, silicon, boron, carbon, etc. as components. In addition to ceramic materials containing oxides (such as alumina or zirconia), carbides (such as silicon carbide or titanium carbide), nitrides (such as silicon nitride or titanium nitride), or borides (such as chromium boride), ceramics can contain a glass material having an amorphous structure in at least a part thereof. Carbon is a carbon material such as crystalline graphite or fiber-reinforced graphite.

[0043] Figure 1 The reaction apparatus 10 shown in is horizontally placed, and atFigure 1 It includes a supply port 101 at its upper left end and a discharge port 102 at its lower right end. Figure 1 The reaction vessel 100 shown therein receives the object to be processed R10 from the supply port 101. The reaction device 10 conveys the object to be processed R10 received by the reaction vessel 100 from the supply port 101 (A1) of the reaction vessel 100 to the discharge port 102 (A2) of the reaction vessel 100 through the middle part A3 by means of a conveying mechanism 120 provided in the reaction vessel 100. The reaction device 10 manufactures a product R11 from the object to be processed R10 by passing the object to be processed R10 through the middle part A3 of the reaction vessel 100. Then, the reaction vessel 100 discharges the manufactured product R11 from the discharge port 102.

[0044] The temperature control region 110 includes a temperature control device, that is, a heating device or a cooling device, and controls the temperature of the reaction vessel at a predetermined position in the middle part A3 between the supply port 101 and the discharge port 102. The temperature control region 110 etc. are examples of the temperature control part of the present disclosure. Figure 1 The temperature control region 110 shown therein includes a heating device at the middle part A3 of the reaction vessel 100, and the heating device surrounds the periphery of the reaction vessel 100 having a cylindrical shape. Examples of the heating device include any heater capable of controlling temperature, such as a sheathed heater, a coil heater, or a ceramic heater. The heating device performs heating, for example, in the range from the ambient temperature to about 1000 degrees Celsius. The temperature control region 110 may include such a configuration in which it surrounds the periphery of the reaction vessel 100 having a cylindrical shape in a separated manner by using a plurality of heating devices in the middle part A3 of the reaction vessel 100. Therefore, different temperatures can be set, for example, for the upper part, the lower part, the left part, and the right part around the reaction vessel 100. In addition, the temperature of the middle part A3 can also be controlled for each different region in the short-axis direction of the reaction vessel 100. For each region of the middle part A3 of the reaction vessel 100, the temperature control region 110 can also set different temperatures along the axis AX 120 of the conveying mechanism 120, which will be described later. The temperature control region 110 can, for example, control the temperature change applied to the object to be processed R10 in the first fluid control region 130 and the second fluid control region 140, which will be described later.

[0045] The temperature control region 110 may also include a control device for controlling the heating device or the cooling device. The temperature control region 110 may, for example, include a thermometer for monitoring the temperature at a predetermined position in the reaction vessel 100. In the case where the heating device, for example, has a principle of heating by passing an electric current, the reaction vessel 100 can perform temperature control by monitoring the current value.

[0046] The temperature control region 110 may have such a configuration that heating or cooling is achieved by circulating water or oil or the like. The temperature control region 110 may have such a configuration that cooling is achieved by using a Peltier element or the like. With the above configuration, the temperature control region 110 can set various temperature distributions along the axis AX of the conveying mechanism 120 in the reaction vessel 100. 120 in the direction.

[0047] As described above, the temperature control region 110 can control the temperature of the reaction vessel 100 (such as the middle part A3) for each different region in the reaction vessel 100 in the direction of the long axis AX of the reaction vessel 100. 100

[0048] The conveying mechanism 120 extends, for example, from one end side A1 of the reaction vessel 100 to the other end side A2, and thus conveys the object to be processed R10 supplied from the supply port 101 toward the discharge port 102. The shape and conveying method of the conveying mechanism 120 according to the present disclosure are not limited as long as the conveying mechanism 120 can convey raw materials, products, etc. The conveying mechanism 120 may be a screw provided in the reaction vessel 100 so as to extend from one end side to the other end side of the reaction vessel 100. The conveying mechanism 120 may be a drum provided in the reaction vessel 100 so as to extend from one end side to the other end side of the reaction vessel 100. The conveying mechanism 120 may be a belt conveyor provided in the reaction vessel 100 so as to extend from one end side to the other end side of the reaction vessel 100. The conveying mechanism 120 may be a blowing 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 devices.

[0049] The size of the conveying mechanism 120 is not particularly limited and may be shorter than the overall length of the reaction vessel 100, for example. Although the material for forming the conveying mechanism 120 is not particularly limited, like the reaction vessel 100, it is desirable that the conveying mechanism 120 is formed of a material that allows temperature changes generated during the production of the product and allows contact with the substances (objects to be processed, etc.) supplied to the vessel or the substances to be produced (products, etc.). The conveying mechanism may be formed of an alloy, ceramic, carbon, or a composite material containing two or more of the above.

[0050] Figure 1 The conveying mechanism 120 shown in, for example, is a screw and has a convex portion 121 with a spiral shape formed around the main shaft extending in the longitudinal axis direction of the reaction vessel 100. Due to the rotation of the convex portion 121 and the contact between the convex portion 121 and the object to be processed R10, the conveying mechanism 120 conveys the object to be processed R10 from the supply port side to the discharge port side.

[0051] Figure 1The shape of the convex portion 121 shown is merely an example, and the shape of the convex portion 121 is not limited to this shape. The convex portion 121 may have different shapes for corresponding regions in the reaction vessel 100. More specifically, for example, the pitch of the helix of the convex portion 121 may be variable. The helical shape of the convex portion 121 does not need to be a single helix and may be a double helix or a multi-helix. The convex portion 121 may include portions without a helical shape. Further, the convex portion 121 may be provided in a direction that forms a 90-degree angle with respect to the longitudinal axis direction of the screw at the top of the convex portion. The convex portion 121 may also extend in a direction that forms a 0-degree angle with respect to the longitudinal axis direction of the screw. Thus, the reaction device 10 can set the moving speed of the object present in the reaction vessel 100, the behavior during movement, etc. for corresponding regions. More specifically, the reaction device 10 conveys, stirs, mixes, retains, kneads, or crushes the object in the reaction vessel 100, for example.

[0052] The conveying mechanism 120 is pivotally supported at both end portions (one end side A1 and the other end side A2) of the reaction vessel 100. Further, Figure 1 The conveying mechanism 120 shown is a screw and is connected (coupled) to the drive device 150 at one end side B1 of the reaction vessel 100. The drive device 150 is an example of a drive device for the conveying mechanism 120 according to the present disclosure. The drive device 150 includes a motor 151 provided on one end side of the reaction device 10 and a speed reducer 152 provided between the motor 151 and one end side A1 of the reaction vessel 100. The speed reducer 152 includes an input shaft coupled to the rotation shaft of the motor 151 and an output shaft coupled to one end side B1 of the conveying mechanism 120, and rotates the conveying mechanism 120 by reducing the rotation of the rotation shaft of the motor 151 and transmitting it to the conveying mechanism 120. Note that the drive device 150 may be set to be able to change the rotation speed of the conveying mechanism 120. In this case, the drive device 150 may be a motor with a variable rotation speed or may be a device obtained by combining a motor with a constant rotation speed and a speed reducer with a variable reduction ratio.

[0053] The first fluid control region 130 includes a first fluid inlet 131 and a first fluid outlet 132 to allow a first fluid to pass through the reaction vessel 100 in a predetermined region in the middle portion A3. The first fluid control region 130 is provided between the supply port 101 on the reaction vessel 100 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 supplied from the first fluid supply pipe 133 to the reaction vessel 100. The first fluid supply pipe 133 includes a first valve 134 for adjusting the flow rate of the first fluid. In addition, the first fluid supply pipe 133 can supply the first fluid to the reaction vessel 100 while intermittently controlling the time by opening and closing the first valve 134. The first fluid outlet 132 connected to the first fluid discharge pipe 135 is a hole for discharging the fluid in the first fluid control region 130 to the outside of the reaction vessel 100. The first fluid discharge pipe 135 can include a valve or a discharge mechanism for adjusting the flow rate or flow 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 an ejector. In another example, a plurality of first fluid inlets 131 and a plurality of first fluid outlets 132 can be provided. The positions of the first fluid inlet 131 and the first fluid outlet 132 in the first fluid control region 130 are not particularly limited, and they can be provided in the upper part, the lower part, or the side part of the reaction vessel 100. The first fluid inlet 131 can be provided in the lower part of the reaction vessel 100, and the first fluid outlet 132 can be provided in the upper part of the reaction vessel 100 so that an air flow is generated in a predetermined direction inside the reaction vessel. With this configuration, the first fluid can easily come into contact with the object to be treated, so that the reaction of the object to be treated can be appropriately carried out. The inner diameter of the first fluid inlet 131 can be set to be smaller than the inner diameter of the first fluid supply pipe 133, so that when the first fluid is supplied to the reaction vessel 100, the first fluid is vaporized. With this configuration, the temperature of the atmosphere around the object to be treated can be adjusted by the heat of vaporization, so that the reaction of the object to be treated can be appropriately controlled.

[0054] With the above configuration, the reaction device 10 turns the object to be processed R10 into an intermediate by bringing the object to be processed R10 into contact with the first fluid in the first fluid control region 130. In addition, the reaction device 10 discharges the fluid that has come into contact with the object to be processed R10 outside the first fluid control region 130. Further, in the reaction device 10, the conveying mechanism 120 rotates to convey the object to be processed R10 or the intermediate, thereby also bringing it into contact with the first fluid, and thus promoting the reaction caused by the first fluid. The form and composition of the first fluid are not limited as long as the first fluid has fluidity. The first fluid may be a gas or may be a liquid. The first fluid may be a dispersion in which a solid is dispersed in a liquid. Further, by supplying the first fluid to the reaction device 10, the temperatures of the reaction vessel 100 and the conveying mechanism 120 can be partially controlled. Accordingly, the reaction device 10 can efficiently control the temperature of the object to be processed R10 and efficiently turn the object to be processed R10 into an intermediate. A mechanism for adjusting the temperature and pressure of the first fluid before supplying the first fluid to the reaction vessel 100 may be provided.

[0055] The second fluid control region 140 includes a second fluid inlet 141 and a second fluid outlet 142 for allowing the second fluid to pass through in a region different from the first fluid control region 130 in the intermediate portion A3. That is, the second fluid control region 140 may have a configuration equivalent to that of the first fluid control region 130 in a region different from the first fluid control region 130.

[0056] The second fluid control region 140 is provided between the first fluid control region 130 and the discharge port 102 in the reaction vessel 100. The second fluid inlet 141 is connected to a second fluid supply pipe 143 and supplies the second fluid supplied from the second fluid supply pipe 143 to the reaction vessel 100. The second fluid supply pipe 143 includes a second valve 144 for adjusting the flow rate of the second fluid. Further, the second fluid supply pipe 143 can supply the second fluid to the reaction vessel 100 while controlling the time for supplying the second fluid to the reaction vessel 100 so as to be supplied at intermittent time intervals by opening and closing the second valve 144. The second fluid outlet 142 connected to the second fluid discharge pipe 145 is a hole for discharging the fluid in the second fluid control region 140 outside the reaction vessel 100. The second fluid discharge pipe 145 may include a valve or a discharge mechanism for adjusting the flow rate or flow velocity of the fluid discharged from the reaction vessel 100. The discharge mechanism is, for example, a suction mechanism such as a pump or an ejector. The first fluid inlet 131, the first fluid outlet 132, and the first valve 134 are examples of the fluid supply portion of the present disclosure.

[0057] With the above configuration, the reaction device 10 causes the intermediate after passing through the first fluid control region 130 to contact the second fluid in the second fluid control region 140 to produce the product R11. In addition, the reaction device 10 discharges the fluid after contacting the intermediate out of the second fluid control region 140. The form and composition of the second fluid are not limited as long as the second fluid has fluidity. The second fluid can be a gas or can be a liquid. The second fluid can be a dispersion in which solids are dispersed in a liquid. By supplying the second fluid to the reaction device 10, the temperatures of the reaction vessel 100 and the conveying mechanism 120 can be partially controlled. Therefore, the reaction device 10 can efficiently control the temperature of the intermediate and efficiently convert the intermediate into the product R11.

[0058] Although the configuration of the reaction device 10 has been described above, the reaction device 10 according to the first embodiment is not limited to the above configuration. For example, the number of the conveying mechanisms 120 can be one or more, or can be two or more. That is, the reaction device 10 can include a plurality of conveying mechanisms 120 arranged in parallel.

[0059] 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 constant-width figure of Reuleaux. In this case, it is desirable that the conveying mechanism 120 is a screw, and the cross-sectional shape of the convex portion 121 of the screw can be a shape obtained by combining a plurality of arcs corresponding to the constant-width figure of Reuleaux. For example, when the cross-sectional shape inside the reaction vessel 100 is circular, the cross-sectional shape of the screw can be a constant-width figure of Reuleaux composed of three arcs.

[0060] The reaction vessel 100 is not limited to being horizontally parallel, and alternatively can have a predetermined angle with respect to the horizontal plane, and the reaction vessel 100 can have an inclined surface. Although the reaction device 10 includes the first fluid control region 130 and the second fluid control region 140 in the intermediate portion A3, the reaction device 10 can also have a configuration for allowing other fluids to pass through. In other words, the reaction device 10 can have three or more fluid control regions. Alternatively, the reaction device 10 can include only the first fluid control region 130 in the intermediate portion A3. The above reaction device 10 is controlled by a control device that will be described later.

[0061] Next, with reference to Figure 2 , the function of the reaction device 10 will be described. Figure 2 is a block diagram of the reaction device 10 according to the first embodiment. In addition to the components shown in Figure 1 , the reaction device 10 further 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).

[0062] The control device 200 is a circuit board, which includes an arithmetic unit, such as a central processing unit (CPU) or a microcontroller unit (MCU). The control device 200 is communicatively connected to the temperature control device 210, the first fluid control device 230, the second fluid control device 240, and the information input / output unit 250, and controls their components.

The functional components of the control device 200 may be integrated into a single unit or may be discrete components. The functional components of the control device 200 may be implemented by a plurality of individual devices working together.

[0064] The general control unit 201 is connected to each functional component of the control device 200 and controls the overall operation of these functions. The general control unit 201 can, for example, perform operations such as issuing an operation instruction to the conveyance control unit 203 according to the state of the temperature supplied from the temperature control unit 202.

[0065] The temperature control unit 202 is connected to the temperature control device 210 and controls the temperature of the reaction vessel 100 in the temperature control area 110. The temperature control unit 202 includes at least one of a heating device or a cooling device. The temperature control unit 202 may also include more than one thermometer for controlling the temperature.

[0066] The conveyance control unit 203 is connected to the drive device 150 and controls the operation of the drive device 150. The conveyance control unit 203 can, for example, include a motor drive circuit for driving a motor (motor 151) included in the drive device 150. The conveyance control unit 203 may also include a rotation sensor for monitoring the rotation speed of the motor (motor 151).

[0067] The first fluid control unit 204 controls the flow of the first fluid in the first fluid control region 130. More specifically, the first fluid control unit 204 is connected to the 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 pumping the first fluid. The second fluid control unit 205 controls the flow of the second fluid in the second fluid control region 140. More specifically, the second fluid control unit 205 is connected to the 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 pumping the second fluid.

[0068] The IF control unit 206 (IF = Interface) is connected to the information input / output unit 250 and is an interface for exchanging information with the user through the information input / output unit 250. That is, the IF control unit 206 receives the actions performed by the user via the information input / output unit 250 and appropriately supplies information related to the received actions to each component of the control device 200. In addition, the IF control unit 206 controls the state of the display unit included in the information input / output unit 250.

[0069] The storage unit 207 is a storage device that includes a non-volatile memory such as a flash memory or a solid-state drive (SSD, Solid State Disk). The storage unit 207 stores a program that enables the reaction device 10 to implement the functions in the present disclosure. The storage unit 207 also includes a volatile memory and temporarily stores predetermined information when the control device 200 operates. The information input / output unit 250 includes, for example, buttons, switches, or a touch panel, etc., which receive the actions performed by the user. The information input / output unit 250 also includes a display device, etc., that presents information to the user.

[0070] The functional blocks of the reaction device 10 have been described above. With the above configuration, the reaction device 10 conveys the received object to be processed R10 through the conveyance mechanism 120, controls the temperature of the reaction vessel 100, and controls the atmosphere in the first fluid control region 130 and the second fluid control region 140.

[0071] Next, with reference to Figure 3 , a method for manufacturing the product R11 (product manufacturing method) implemented by the reaction device 10 will be described. Figure 3 is a flowchart of the process implemented by the reaction device 10. Figure 3 The flowchart shown in, for example, starts with the supply of the object to be processed R10 to the reaction device 10.

[0072] First, the reaction device 10 receives a predetermined object to be processed R10 from the supply port 101 (step S11).

[0073] Next, the control device 200 of the reaction device 10 controls the temperature by driving a heating device or a cooling device in the temperature control region 110 of the reaction vessel 100 via the temperature control unit 202 (step S12).

[0074] Next, the control device 200 of the reaction device 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 object to be processed R10 toward the discharge port 102 (step S13).

[0075] Next, the control device 200 of the reaction device 10 controls the flow of the first fluid passing through the first fluid control region 130 (first atmosphere control region) via the first fluid control unit 204 (step S14).

[0076] Next, the control device 200 of the reaction device 10 controls the flow of the second fluid passing through the second fluid control region 140 (second atmosphere control region) via the second fluid control unit 205 (step S15).

[0077] Next, the reaction device 10 discharges the product R11 that has passed through the second fluid control region 140 from the discharge port 102 (step S16).

[0078] The reaction method (product manufacturing method) implemented by the reaction device 10 has been described above. The above method is presented along the process of manufacturing the product R11 from the object to be processed R10 by the reaction device 10 and until the manufactured product R11 is discharged. However, the reaction device 10 can perform the temperature control in step S12, for example, even before step S11. In addition, the reaction device 10 can start step S14 and step S15 simultaneously, for example.

[0079] The first embodiment (reference example) has been described above. Although in the above reaction device 10, the reaction device 10 includes two fluid control regions (the first fluid control region 130 and the second fluid control region 140), the reaction device 10 can alternatively include one fluid control region or three or more fluid control regions. The reaction device 10 can also include a plurality of temperature control regions 110 along the axis AX 120 of the transport mechanism 120 (major axis direction). The above reaction device 10 causes a plurality of fluids to contact the object to be processed R10 received from the supply port 101 at the intermediate portion A3. In addition, the reaction device 10 is along the axis AX of the transport mechanism 120 in the intermediate portion A3 120The direction (major axis direction) controls the temperature of the reaction vessel 100. In addition, the reaction device 10 can transport the object inside the reaction vessel 100 and provide physical stimulation. The reaction device 10 can simultaneously and precisely perform the above-described atmosphere control, temperature control, and physical control. Therefore, according to the first embodiment, a reaction device and the like for efficiently manufacturing a desired product can be provided.

[0080] <Second Embodiment>

[0081] Next, as the second embodiment, with reference to Figure 4 , a structural example of the support for the reaction vessel 100 and a structural example of the support transport mechanism 120 will be described. This structural example can be applied to the above-described first embodiment (reference example). Figure 4 is a side view of the reaction device according to the second embodiment. Figure 4 Corresponds to the figure obtained by adding the first support portion 103 and the second support portion 104 to the composition shown in Figure 1 The other structure is similar to the structure of Figure 1 . Hereinafter, the differences between the first embodiment (reference example) and the second embodiment will be mainly described.

[0082] <Structural Example of Supporting Reaction Vessel 100>

[0083] As shown in Figure 4 , the reaction device 10 includes a first support portion 103 and a second support portion 104 as components for supporting the reaction vessel 100. Figure 4 The reaction vessel 100 shown in

[0084] is a cylindrical reaction vessel (furnace), including an intermediate portion A3 between one end side A1 and the other end side A2, and is supported by the first support portion 103 and the second support portion 104 provided on the ground 170. The ground 170 can be the ground of the building on which the reaction device 10 is installed, or for example, can be a part of the surface forming the structure of the reaction device 10, such as the upper surface of the mounting base. 100It is supported in a state of moving in the direction of. This is achieved, for example, by fixing one end side A1 of the reaction vessel 100 supported by the first support portion 103 to the first support portion 103 by direct fixing means such as bolts or welding. Alternatively, instead of the direct fixing means, this can be achieved, for example, by bringing a member such as a plate or a wire separately fixed to a mounting base or the like into contact with one end side A1 of the reaction vessel 100 supported by the first support portion 103, and then indirectly fixing one end side A1 of the reaction vessel 100 to the first support portion 103.

[0085] On the other hand, the second support portion 104 provided on the ground 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 in a state where it can move in the direction of the long axis AX of the reaction vessel 100 100 It is supported in a state of moving in the direction of. This is achieved, for example, by the specific examples 1-3 described later.

[0086] Support the other end side A2 of the reaction vessel 100 in a state where it can move in the direction of the long axis AX of the reaction vessel 100 100 The technical significance of supporting the other end side A2 of the reaction vessel 100 in a state where it can move in the direction of the long axis AX of the reaction vessel 100 is as follows.

[0087] That is, as described in the above first embodiment (reference example), when the temperature of the reaction vessel 100 is controlled by a temperature control device 210 or the like (for example, when the reaction vessel 100 is heated from the ambient temperature to about 900 degrees), the reaction vessel 100 thermally expands in the direction of the long axis AX 100 in the direction of (for example, thermally expands about 10-20 mm in the direction of the long axis AX 100 in the direction of). At this time, if the other end side A2 of the reaction vessel 100 cannot move in the direction of the long axis AX 100 in the direction of, due to the thermal expansion of the reaction vessel 100 in the direction of the long axis AX 100 in the direction of, a force acts on the drive device 150, which may cause damage to the drive device 150. For example, it is possible that the rotating shaft of the (one or more) gears forming the drive device 150 (such as a speed reducer) may be deformed, and thus the drive device 150 (such as a speed reducer) cannot operate normally. Or, it is possible that the conveying mechanism 120 may be significantly deformed, which prevents the conveying mechanism 120 from performing normal conveyance.

[0088] To prevent a situation where a force acts on the drive device 150 due to the thermal expansion of the reaction vessel 100 in the direction of the long axis AX 100 in the direction of and the drive device 150 is damaged, for example, the second support portion 104 supports the other end side A2 of the reaction vessel 100 in a state where it can move in the direction of the long axis AX of the reaction vessel 100 100 in the direction of.

[0089] Next, a specific example of supporting the other end side A2 of the reaction vessel 100 in a state where it can move in the direction of the long axis AX of the reaction vessel 100 will be described. 100 in the direction will be described.

[0090] <Specific Example 1>

[0091] Figure 5A FIG. shows Specific Example 1, in which the other end side A2 of the reaction vessel 100 is supported in a state where it can move in the direction of the long axis AX of the reaction vessel 100. 100 in the direction. Figure 5A is a perspective view seen from the direction of arrow AR1 in Figure 4 .

[0092] As Figure 5A shown in, Specific Example 1 is an example in which, in order to enable the other end side A2 of the reaction vessel 100 to move in the direction of the long axis AX of the reaction vessel 100, the other end side A2 of the reaction vessel 100 is supported in such a state that a flange portion 109 is provided on the other end side A2 of the reaction vessel 100, a concave portion 109a is formed in the lower portion of the flange portion 109, a convex portion 104a inserted into the concave portion 109a is provided on the upper portion of the second support portion 104, and the convex portion 104a is inserted into the concave portion 109a.

A gap G1 is formed between the lower surface 109b of the flange portion 109 and the upper surface 104b of the second support portion 104. Lubricating oil or the like can be supplied to the portion between the concave portion 109a and the convex portion 104a. Conversely, the convex portion 104a may be provided in the lower portion of the flange portion 109, and the concave portion 109a into which the convex portion 104a is inserted may be formed in the upper portion of the second support portion 104. 100 in the direction. 100 in the direction.

[0093] <Specific Example 2>

[0094] Figure 5B FIG. shows Specific Example 2, in which the other end side A2 of the reaction vessel 100 is supported in a state where it can move in the direction of the long axis AX of the reaction vessel 100. 100 in the direction. Figure 5B is a perspective view seen from the direction of arrow AR1 in Figure 4 .

[0095] As Figure 5B shown in, Specific Example 2 is an example in which, in order to enable the other end side A2 of the reaction vessel 100 to move in the direction of the long axis AX of the reaction vessel 100, 100moves in the direction of, and the other end side A2 of the reaction vessel 100 is supported in such a state that the flange portion 109 is provided on the other end side A2 of the reaction vessel 100, the friction reduction member 111 is provided on the upper surface 104b of the second support portion 104, and the lower surface 109b of the flange portion 109 contacts the friction reduction member 111. The form, shape, and material of the friction reduction member 111 are not particularly limited as long as the friction reduction member 111 is a member that can enable the smooth movement of the reaction vessel 100. The friction reduction member 111 can be, for example, a member including a rotating portion, such as a roller or a belt. The friction reduction member 111 can be a member made of a high-hardness material, such as a tool steel material capable of quenching heat treatment, a nitrided steel material capable of nitriding heat treatment, a powder metallurgy material containing ceramic particles in at least a part of the friction reduction member 111, or a steel material with a coating on the surface, wherein the Vickers hardness (HV) of the surface of the friction reduction member 111 that supports the reaction vessel 100 is 450 or more, or its Rockwell hardness (HRC) is 45 or more. The friction reduction member 111 can be, for example, a member having a surface coated with diamond-like carbon (DLC), titanium carbide (TiC), titanium carbonitride (TiBN), titanium boride (TiB2), vanadium carbide (VC), alumina (Al2O3), zirconia (ZrO2), etc. by film-forming means, such as CVD, PVD, or thermal spraying. The friction reduction member 111 can be a member having a surface coated with chromium plating or nickel plating (Ni-P or Ni-Co-W) by electroplating or electroless plating. In addition, the friction reduction member 111 can be a member having a surface coated with a composition having solid lubrication characteristics by an application means, such as spraying. That is, the chemical composition of the surface (support surface) of the friction reduction member 111 that supports the reaction vessel 100 preferably contains at least one of the elements (chemical elements) of B, C, N, Al, P, Ti, V, Cr, Co, Ni, Mo, and W.

[0096] <Specific Example 3>

[0097] Figure 5C is a view showing Specific Example 3, in which the other end side A2 of the reaction vessel 100 is supported in a state where it can move in the long axis AX of the reaction vessel 100 100 in the direction. Figure 5C is from Figure 4 the direction of arrow AR1 in.

[0098] As Figure 5C shown in, Specific Example 3 is an example in which, in order to enable the other end side A2 of the reaction vessel 100 to move in the long axis AX of the reaction vessel 100 100It moves in the direction of, and the other end side A2 of the reaction vessel 100 is supported in such a state that a flange portion 109 including protruding portions 109c and 109d protruding on the left and right sides (protruding in a direction intersecting (e.g., perpendicular to) the long axis of the reaction vessel 100) is provided on the other end side A2 of the reaction vessel 100, upright portions 104c and 104d are provided on the upper surface 104b of the second support portion 104, and the protruding portions 109c and 109d are placed on the upright portions 104c and 104d. A gap G2 is formed between the lower surface 109b of the flange portion 109 and the upper 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 upright portions 104c and 104d. Lubricating oil or the like can be supplied between the protruding portions 109c and 109d and the upright portions 104c and 104d.

[0099] As in the above specific examples 1-3, the other end side A2 of the reaction vessel 100 is supported in a state where it can move in the direction of the long axis AX of the reaction vessel 100 100 Thereby, it is possible to prevent a situation where a force acts on the drive device 150 due to thermal expansion (or thermal contraction) of the reaction vessel 100 in the direction of the long axis AX 100 of the reaction vessel 100, which may cause damage to the drive device 150, for example.

[0100] <Structural example of the support and conveyance mechanism 120>

[0101] As Figure 4 shown, the reaction device 10 includes bearings 106 and 107 as a structure for supporting the screw of the conveyance mechanism 120.

[0102] The bearing 106 is provided on one end side A1 of the reaction vessel 100 and rotatably supports one end side B1 of the conveyance mechanism 120. The bearing 106 is, for example, a bearing or a bushing. One end side B1 of the conveyance mechanism 120 is coupled (fixed) to the output shaft of the speed reducer 152. That is, one end side B1 of the conveyance mechanism 120 is rotatably supported and in a state where it cannot move in the direction of the axis AX 120 of the conveyance mechanism 120.

[0103] On the other hand, the bearing 107 is provided on the other end side A2 of the reaction vessel 100, and rotatably supports the other end side B2 of the conveyance mechanism 120 and in a state where it can move in the direction of the axis AX 120 of the conveyance mechanism 120. The bearing 107 is an example of the third support portion and the sixth support portion of the present disclosure. The bearing 107 is, for example, a bearing or a bushing. In order to enable the other end side B2 of the conveyance mechanism 120 to move in the direction of the axis AX 120moves in the direction of, and the convex portion 121 having a spiral shape is not provided within a predetermined range (see Figure 4 the range indicated by symbol L1 in 120 ) on the other end side B2 of the conveying mechanism 120. Further, a space (see Figure 4 the range indicated by symbol L2 in Figure 4 ) into which the other end side B2 of the conveying mechanism 120 moving in the direction of

[0104] the right side of 120 the axis AX of the conveying mechanism 120 enters is provided between the end of the other end side B2 of the conveying mechanism 120 and the lid portion 108 provided on the other end side A2 of the reaction vessel 100. 100 The axis AX of the conveying mechanism 120 supported in the above manner

[0105] and the major axis AX of the reaction vessel 100 120 coincide (substantially coincide).

[0106] That is, as described in the above first embodiment (reference example), when the temperature of the reaction vessel 100 is controlled by a temperature control device 210 or the like (for example, when the reaction vessel 100 is heated from the ambient temperature to about 900 degrees Celsius), the reaction vessel 100 thermally expands in the direction of 100 the major axis AX (for example, expands by about 10 - 20 mm in the direction of 100 the major axis AX). At the same time, the conveying mechanism 120 also thermally expands in the direction of 120 its axis AX (for example, thermally expands by about 10 - 20 mm in the direction of 120 the axis AX). At this time, if the other end side B2 of the conveying mechanism 120 cannot move in the direction of 120 the axis AX, it is possible that the conveying mechanism 120 may be deformed due to the thermal expansion of the conveying mechanism 120 in the direction of 120 the axis AX, which causes the convex portion 121 having a spiral shape or the like of the deformed conveying mechanism 120 to contact the inner wall of the reaction vessel 100, so that the conveying mechanism 120 cannot rotate normally, for example.

[0107] Further, if one end side B1 of the conveying mechanism 120 is designed to be movable in the direction of 120 the axis AX of the conveying mechanism 120, and the other end side B2 of the conveying mechanism 120 is designed to be immovable in the direction of 120If it moves in the direction of, the other end side B2 of the conveying mechanism 120 moves along with the thermal expansion or contraction of the reaction vessel 100, making it difficult to control the positions of the convex and concave portions of the screw, and the object to be processed, for example, cannot react normally.

[0108] To prevent the conveying mechanism 120 from deforming due to the thermal expansion of the conveying mechanism 120 in the axial direction AX 120 the other end side B2 of the conveying mechanism 120 is rotatably supported by a bearing 107 and is supported in a state where it can move in the axial direction AX of the conveying mechanism 120 120 in the direction.

[0109] As described above, by rotatably supporting the other end side B2 of the conveying mechanism 120 and in a state where it can move in the axial direction AX of the conveying mechanism 120 120 it is possible to prevent the conveying mechanism 120 from deforming due to the thermal expansion of the conveying mechanism 120 in its axial direction AX 120 in the direction.

[0110] As described above, according to the second embodiment, the reaction device 10 can be provided, and even if the reaction vessel 100 thermally expands in the direction of the long axis AX 100 this reaction device can prevent the reaction vessel 100 from malfunctioning due to thermal expansion.

[0111] Next, examples of modifications will be described.

[0112] Although an example of using a reaction vessel 100 that is non-rotatably supported has been described in the second embodiment above, this is merely an example. For example, a reaction vessel 100 that is rotatably supported can be used alternatively.

[0113] Figure 6 is a structural example of a reaction vessel 100 that is rotatably supported.

[0114] As Figure 6 shown in, the reaction device 10 according to this example of the modification includes bearings 112 and 113 as components for rotatably supporting the reaction vessel 100.

[0115] The bearing 112 is provided between one end side A1 of the reaction vessel 100 and the first support portion 103, and rotatably supports one end side A1 of the reaction vessel 100 and in a state where it cannot move in the direction of the long axis AX of the reaction vessel 100 100 in the direction. The bearing 112 is, for example, a ball bearing or a bushing. A flange portion 114 is provided on one end side A1 of the reaction vessel 100. The flange portion 114 contacts the bearing 112, which prevents one end side A1 of the reaction vessel 100 from moving in the direction of the long axis AX of the reaction vessel 100 100 in the direction (Figure 6 moves upward on the right side in []. A plurality of flange portions 114 and a plurality of bearings 112 can be provided. For example, by providing two bearings 112 for one flange portion 114 and sandwiching the flange portion 114 between the bearings 112, it is possible to more preferably prevent one end side A1 of the reaction vessel 100 from moving in the long axis AX of the reaction vessel 100 100 in the direction. The bearing 112 can be an annular bearing or bushing into which one end side A1 of the reaction vessel 100 is inserted, or can be an arc-shaped bearing or bushing obtained by cutting off a part of the annular bearing or bushing. Instead of the bearing 112, a member made of a lubricating material can be used to rotatably support one end side A1 of the reaction vessel 100 and in a state where it cannot move in the long axis AX of the reaction vessel 100 100 in the direction. The bearing 112 and the flange portion 114 are examples of the fourth support portion of the present disclosure.

[0116] On the other hand, a bearing 113 is provided between the other end side A2 of the reaction vessel 100 and the second support portion 104, and rotatably supports the other end side A2 of the reaction vessel 100 and in a state where it can move in the long axis AX of the reaction vessel 100 100 in the direction. The bearing 113 is, for example, a bearing or a bushing. The bearing 113 can be an annular bearing or bushing into which the other end side A2 of the reaction vessel 100 is inserted, or can be an arc-shaped bearing or bushing obtained by cutting off a part of the annular bearing or bushing. Instead of the bearing 113, a member made of a lubricating material can be used to rotatably support the other end side A2 of the reaction vessel 100 and in a state where it can move in the long axis AX of the reaction vessel 100 100 in the direction. The bearing 113 is an example of the fifth support portion of the present disclosure. Similar to the drive device 150 (screw drive device), the rotatably supported reaction vessel 100 according to the example of this modification is connected (coupled) to the reaction vessel drive device 116 at one end side A1 ( Figure 6 not shown in []).

[0117] As in the example of this modification, in the case of using a configuration that rotatably supports the reaction vessel 100, a rotatably supported conveying mechanism 120 (see Figure 4 ) can be used, or a non-rotatably supported conveying mechanism 120 (not shown) can be used instead of the rotatably supported conveying mechanism 120. In addition, the conveying mechanism 120 can be omitted.

[0118] In addition, although such an example has been described above in the second embodiment, where the first support portion 103 that supports one end side A1 of the reaction vessel 100 from below serves as the first support portion, this is merely an example. That is, the first support portion can have any configuration as long as it supports one end side A1 of the reaction vessel 100 in a state where it cannot move in the direction of the long axis AX 100 For example, although not shown in the drawings, a first support portion that supports one end side A1 of the reaction vessel 100 in such a manner that the first support portion hangs one end side A1 of the reaction vessel 100 from above can serve as the first support portion, or a first support portion that supports one end side A1 of the reaction vessel 100 from the side portion can be used.

[0119] In addition, although such an example has been described in the second embodiment above, where the support portion that supports the other end side A2 of the reaction vessel 100 from the bottom serves as the second support portion 104, this is merely an example. That is, the second support portion can have any configuration as long as the second support portion supports the other end side A2 of the reaction vessel 100 in a state where it can move in the direction of the long axis AX 100 For example, although not shown in the drawings, a second support portion that supports the other end side A2 of the reaction vessel 100 in such a manner that the second support portion hangs the other end side A2 of the reaction vessel 100 from above can serve as the second support portion, or a second support portion that supports the other end side A2 of the reaction vessel 100 from the side portion can be used.

[0120] Although as Figure 5A and Figure 7 shown in the above embodiment, such an example has been described where the second support portion 104 supports the other end side A2 of the reaction vessel 100 in a state where it can only move in the direction of the long axis AX 100 of the reaction vessel 100, this is merely an example. Figure 7 is an arrow view as viewed from the direction of the arrow AR2 in Figure 5A . For example, in addition to being able to move in the direction of the long axis AX 100 of the reaction vessel 100, the other end side A2 of the reaction vessel 100 can also be supported in a state where it can rotate about the rotation axis AX V (vertical axis).

[0121] Next, a specific example 4 will be described, where in addition to being able to move in the direction of the long axis AX 100 of the reaction vessel 100, the other end side A2 of the reaction vessel 100 is also supported in a state where it can rotate about the rotation axis AX V (vertical axis).

[0122] <Specific Example 4>

[0123] Figure 8 is a schematic view of Specific Example 4, in which the other end side A2 of the reaction vessel 100 can move not only in the direction of the long axis AX of the reaction vessel 100 100 but also is supported in a state where it can rotate about the rotation axis AX V (vertical axis).

[0124] As Figure 8 shown, the convex portion 104a is provided on the base 104e, and the base is supported by the second support portion 104 (upper surface 104b) via a bearing or the like so as to be rotatable about the rotation axis AX V (vertical axis). Note that in Figure 8 , the rotation axis AX V extends in a direction perpendicular to the paper surface. Therefore, the other end side A2 of the reaction vessel 100 can move not only in the direction of the long axis AX of the reaction vessel 100 100 but also is supported in a state where it can rotate about the rotation axis AX V (vertical axis).

[0125] As described above, in addition to being movable in the direction of the long axis AX of the reaction vessel 100 100 , the other end side A2 of the reaction vessel 100 is supported in a state where it can rotate about the rotation axis AX V (vertical axis), and the advantages are as follows.

[0126] That is, in Figure 7 , according to the state of the reaction (state of physical stimulation), a temperature difference (or a temperature difference can be deliberately generated) may exist between the temperature on the right side and the temperature on the left side of the long axis AX of the reaction vessel 100 100 . In this case, the following phenomenon occurs: the extension amounts on the right side and the left side of the long axis AX of the reaction vessel 100 100 are different from each other.

[0127] For example, in Figure 7 , if the temperature on the right side of the long axis AX of the reaction vessel 100 100 is higher and the temperature on the left side is lower, the right side of the long axis AX of the reaction vessel 100 100 extends longer, while the left side extends shorter. Figure 7 The lengths of the arrows AR3 and AR4 in

[0128] represent this situation. 100 If the extension amounts on the right side and the left side of the long axis AX of the reaction vessel 100 Figure 7 are different from each other, a stress in the horizontal direction can be generated on the other end side A2 of the reaction vessel 100 (see the arrow AR5 in

[0129] If such stress is generated, the friction generated between the second support portion 104 (protrusion 104a) and the flange portion 109 (recess 109a) may prevent the reaction vessel 100 (the other end side A2) from moving in the direction of the long axis AX 100 of the reaction vessel 100.

[0130] By adopting the structure shown in Figure 8 , various situations of physical stimuli can be appropriately dealt with.

[0131] When a biaxial reaction vessel 100A is adopted (see Figure 9 ), a state in which a temperature difference is deliberately generated between the temperature on the right side and the temperature on the left side of the reaction vessel 100 is particularly effective for controlling, for example, the reaction rate of the object to be processed. Figure 9 is an example of the biaxial reaction vessel 100A.

[0132] Next, a specific example 5 will be described, in which the other end side A2 of the reaction vessel 100 is supported such that it can move not only in the direction of the long axis AX 100 of the reaction vessel 100 but also in the short-axis direction (see the arrow AR6 in Figure 10 ).

[0133] <Specific Example 5>

[0134] Figure 10 is a schematic view of the specific example 5, in which the other end side A2 of the reaction vessel 100 is supported in a state where it can move not only in the direction of the long axis AX 100 of the reaction vessel 100 but also in the short-axis direction (see the arrow AR6 in Figure 10 ).

[0135] As shown in Figure 10 , the protrusion 104a is provided on the base 104e, and the base is supported by the second support portion 104 (upper surface 104b) via a bearing or the like so as to be rotatable about the rotation axis AX V (vertical axis). Further, the base 104e is provided on the guide rail 104f (supported by the second support portion 104 (upper surface 104b)) so that it can also move in the short-axis direction (see the arrow AR6 in Figure 10 ). Note that in Figure 10 , the rotation axis AX V extends in a direction perpendicular to the paper surface. Therefore, the other end side A2 of the reaction vessel 100 can move not only in the direction of the long axis AX 100 of the reaction vessel 100 but also rotate about the rotation axis AX V (vertical axis) and move in the short-axis direction (see the arrow AR6 inFigure 10 while being supported in a state of moving on the arrow AR6) in

[0136] As described above, in addition to being movable in the direction of the long axis AX of the reaction vessel 100 100 the other end side A2 of the reaction vessel 100 can rotate around the rotation axis AX V (vertical axis) and can be supported in a state of being movable in the short axis direction (see Figure 10 the arrow AR6) in

[0137] In the case where the above stress is generated (see Figure 7 the arrow AR5) in 100 friction generated between the second support portion 104 (protrusion 104a) and the flange portion 109 (recess 109a) can prevent the reaction vessel 100 (the other end side A2) from moving in the direction of the long axis AX

[0138] If the above deformation further increases (if the above stress further increases), the other end side A2 of the reaction vessel 100 can be inclined (see Figure 11B ) and the reaction vessel 100 can be twisted (see Figure 11A ). Figure 11A is a diagram showing a state where the reaction vessel 100 is twisted, Figure 11B is a diagram showing a state where the reaction vessel 100 is inclined. Twisting and inclination tend to occur at the other end side A2 or the middle portion A3.

[0139] To solve the above problems, by adopting the structure shown in Figure 10 it is possible to suppress the twisting of the reaction vessel 100 (see Figure 11C and 11D ). Figure 11C is a diagram showing a state where the twisting of the reaction vessel 100 is suppressed, Figure 11D is a diagram showing a state where the inclination of the reaction vessel 100 is suppressed.

[0140] In addition, although such examples have been described in the above first and second embodiments, in which the temperature control unit (temperature control region 110, etc.) controls the temperature of each region of different regions in the direction of the long axis AX of the reaction vessel 100 100 this is merely an example. That is, the number of regions whose temperature is controlled by the temperature control unit (temperature control region 110, etc.) is not limited to two or more and may also be one.

[0141] In addition, although examples have been described in the above first and second embodiments in which a fluid supply unit (the first fluid inlet 131, the first fluid outlet 132, the first valve 134, etc.) is used, these are merely examples. That is, some or all of the fluid supply unit (the first fluid inlet 131, the first fluid outlet 132, the first valve 134, etc.) may be omitted.

[0142] In addition, although examples have been described in the above first and second embodiments in which the drive device 150 is provided on one end side A1 of the reaction vessel 100 and coupled to one end side B1 (e.g., a screw) of the conveying mechanism 120, these are merely examples. Another drive device may be used as a device for driving the conveying mechanism 120.

[0143] Although the invention made by the present inventors has been specifically described with reference to the embodiments, the present invention is not limited to the described embodiments, and it goes without saying that various changes can be made without departing from the spirit of the present invention.

[0144] This application is based on and claims the priority of Japanese Patent Application JP 2022-184879 filed on November 18, 2022, the entire disclosure of which is incorporated herein by reference.
