[0008] Such a reaction device in which a conveying mechanism for conveying a product is provided in a reaction vessel can be used to produce a product with high reactivity. An example of a product with high reactivity is a battery material constituting an all-solid lithium ion battery. The battery material may be, for example, a solid electrolyte or a positive electrode active material at least partially containing sulfur and lithium as components. The battery material may be, for example, a negative electrode material at least partially containing metallic lithium as a component. At the same time, it is known that these battery materials have high reactivity. For example, a solid electrolyte and a positive electrode active material at least partially containing sulfur and lithium as components may react with moisture in the ambient air to produce toxic hydrogen sulfide. A negative electrode material at least partially containing metallic lithium as a component may react with moisture or oxygen in the ambient air to catch fire or deteriorate. In view of these circumstances, when a battery material with high reactivity is trial-produced in a laboratory, etc., a glove box with an adjusted atmosphere is used. For example, the interior of the glove box is an environment in which the dew point temperature is adjusted to below -60 degrees Celsius, so that the amount of moisture in the air is extremely small. In addition, by using an inert gas, such as nitrogen or argon, the interior of the glove box is adjusted to an environment with an extremely low oxygen concentration.

[0009] In order to realize mass production of such a highly reactive battery material, the inventors developed a reaction device by further improving the reaction device described in Patent Document 1. Meanwhile, after the highly reactive battery material is produced, the conveying mechanism can be taken out from the reaction device for maintenance. However, when the conveying mechanism is taken out in the ambient air, the battery material adhered to the conveying mechanism reacts with moisture or oxygen in the ambient air, making it difficult to safely take out the conveying mechanism.

[0010] The present disclosure is made to solve such a problem, and provides a taking-out device and a taking-out method capable of safely taking out a conveying mechanism provided in a reaction container.

[0011] The taking-out device according to the present disclosure is a taking-out device for taking out a conveying mechanism from a reaction device including a reaction container and a conveying mechanism, wherein the reaction container obtains a product by reacting a to-be-processed object loaded in the reaction container, and the conveying mechanism is arranged in the reaction container to convey the to-be-processed object, and the taking-out device includes: a storage container, which is airtightly connected to the reaction container; and a connecting component, which is connected to the conveying mechanism in the storage container, wherein the conveying mechanism is taken out of the reaction container and stored in the storage container by moving the connecting component.

[0012] The removal method according to the present disclosure is a removal method for removing a conveying mechanism from a reaction device including a reaction container and a conveying mechanism, wherein the reaction container obtains a product by reacting a to-be-treated object loaded in the reaction container, and the conveying mechanism is arranged in the reaction container to convey the to-be-treated object, and the method includes the following steps: airtightly connecting a receiving container to the reaction container; connecting a connecting component to the conveying mechanism in the receiving container; and removing the conveying mechanism from the reaction container by moving the connecting component, and storing the conveying mechanism in the receiving container.

[0013] According to the present disclosure, the delivery mechanism disposed in the reaction container can be safely removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Hereinafter, the present invention will be described by the 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 the components described in the embodiments are necessary means to solve the problem. For the sake of clarity, the following description and drawings are appropriately omitted or simplified. In the various drawings, the same elements are given the same figure marks, and repeated descriptions are omitted when appropriate. In the following description, the positional relationship indicated by terms such as "left", "right", "inside", "outside", "axis", "center", "horizontal" and "orthogonal" is based on the positional relationship shown in the drawings, and is intended only to facilitate the description of the embodiments of the present invention, and therefore should not be understood as limiting the embodiments of the present invention.

[0029] First, a reaction device to which the take-out device of the embodiment is applied will be described. Figure 11 is a diagram showing an example of the structure of a reaction device 10 to which the take-out device according to the embodiment is applied. Figure 1 1 is a side view of the reaction device 10 , and shows the state of the reaction device 10 in a partially cutaway manner for easier understanding.

[0030] The reaction device 10 is, for example, a device for producing a product by applying conditions such as a predetermined physical stimulus to the object to be treated. Although the type or state of the object to be treated is not particularly limited, the object to be treated may be an inorganic substance containing lithium as one of the components, such as a metal oxide or a metal sulfide, or may be an organic substance, such as a hydrocarbon. The object to be treated may be a solid, such as a powdery and granular material, or may be a fluid, such as a liquid or a gas. In the process of being converted into a product, the object to be treated may be converted into a product via an intermediate. Although there is no particular restriction on the form or state of the intermediate, in the case of performing two or more reactions in a stepwise manner, the intermediate may 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 is a sintered body, in which at least a portion of the object to be treated is grain-grown or sintered. The intermediate is in a state in which at least a portion of the object to be treated has been liquefied or vaporized. The intermediate may be in a form or state different from that described above.

[0031] The physical stimulus is not particularly limited as long as the physical stimulus is a means used in the process of converting the object to be processed into the product. Examples of physical stimulation include temperature changes, such as heating and cooling. Examples of physical stimulation include stress transmission, such as stirring, mixing, kneading and crushing. The physical stimulus is, for example, a reaction that receives electrons or free radicals. The physical stimulus is, for example, contact with a catalyst.

[0032] The type or state of the product is not particularly limited, and the product may be a solid, such as a powdery and granular 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 product, 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.

[0033] The extraction device of the embodiment is particularly useful in a case where the reaction device 10 produces, for example, a product having high reactivity such as a sulfide-based solid electrolyte which is a material of an all-solid lithium ion battery.

[0034] The reaction device 10 includes a reaction vessel 11, a temperature control area 12, a conveying mechanism 13, a first fluid control area 14, a second fluid control area 15, a supply device 16 and a driving device 17 as main components. The reaction vessel 11 is a cylindrical component including a supply port 18 and a delivery port 19, the supply port 18 receives the supplied object to be processed, and the delivery port 19 delivers the product. The reaction vessel 11 includes an intermediate portion between the supply port 18 and the delivery port 19. The number of supply ports 18 can be one, or it can be two or more. The delivery port 19 can be arranged near the end of the reaction vessel 11, or it can be arranged at a position different from the end of the reaction vessel 11. The delivery port 19 can be arranged between two supply ports 18. In the process of obtaining the product from the object to be processed, the number of the reaction device 10 can be one, or it can be two or more. That is, in order to carry out multiple reactions, multiple reaction devices 10 can be connected in series or in parallel.

[0035] Figure 1 The reaction container 11 shown receives the object R10 to be processed from the supply port 18. The reaction device 10 conveys the object R10 to be processed received by the reaction container 11 to the delivery port 19 by the conveying mechanism 13 provided in the reaction container 11. That is, the object R10 to be processed supplied to the reaction container 11 passes through the middle portion and moves toward the delivery port 19. The reaction device 10 produces a product R11 from the raw material R10 by passing the object R10 to be processed through the middle portion of the reaction container 11. Then, the conveying mechanism 13 delivers the produced product R11 from the delivery port 19.

[0036] Although the material used to form the reaction vessel 11 is not particularly limited, it is desirable to form the reaction vessel 11 from a material that allows temperature changes to occur when the product is produced and allows contact with the substance supplied to the container. The reaction vessel 11 may be formed of, for example, an alloy, a ceramic, carbon, or a composite material comprising two or more of the above. An alloy is a metal material containing at least one alloy element as a component, and the alloy elements include nickel, cobalt, chromium, molybdenum, tungsten, tantalum, titanium, iron, copper, aluminum, silicon, boron, carbon, and the like. Ceramics are ceramic materials including: oxides such as aluminum oxide 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. Carbon is a carbon material such as crystalline graphite or fiber reinforced graphite.

[0037] As long as the conveying mechanism 13 can convey the object to be processed and the product, the shape and conveying method of the conveying mechanism 13 are not limited. The conveying mechanism 13 may be a screw arranged in the reaction container 11 in a manner extending from the supply port side to the delivery port side of the reaction container 11. The conveying mechanism 13 may be a rotating drum arranged in the reaction container 11 in a manner extending from the supply port side to the delivery port side of the reaction container 11. The conveying mechanism 13 may be a belt conveyor arranged in the reaction container 11 in a manner extending from the supply port side to the delivery port side of the reaction container 11. The conveying mechanism 13 may be an air supply device arranged in the reaction container 11. The conveying mechanism 13 may be a vibration generating device arranged in the reaction container 11. The conveying mechanism 13 may be a device different from the above-mentioned devices.

[0038] The size of the delivery mechanism 13 is not particularly limited, and may be, for example, shorter than the entire length of the reaction vessel 11. Although the material used to form the delivery mechanism 13 is not particularly limited, in the same manner as the reaction vessel 11, it is desirable to form the delivery mechanism 13 from a material that allows temperature changes to occur when a product is produced and allows contact with a substance supplied into the vessel. The delivery mechanism 13 may be formed of, for example, an alloy, ceramics, carbon, or a composite material containing two or more of the foregoing.

[0039] Figure 1 The conveying mechanism 13 shown is, for example, a screw, and is pivotally supported at both ends of the reaction container 11. The position of supporting the conveying mechanism 13 is not limited to the two ends. The conveying mechanism 13 is connected to the driving device 17 on the supply port 18 side. The driving device 17 includes a predetermined rotating mechanism, such as a motor, and rotates the conveying mechanism 13. The driving device 17 may be configured to be able to change the conveying speed of the conveying mechanism 13. In this case, the driving device 17 may be a motor with a variable speed, or may be a device obtained by combining a motor with a constant speed and a reducer with a variable reduction ratio.

[0040] exist Figure 1 When the screw rotates, the object to be processed R10 supplied from the supply port 18 is transported toward the delivery port 19. Figure 1 In the example shown, a protrusion 131 having a spiral shape is formed on the outer periphery of the shaft of the conveying mechanism 13, which is Figure 1 Due to the rotation of the protrusion 131 and the contact with the object to be processed R10, the conveying mechanism 13 moves the object to be processed R10 from Figure 1 The left side is transported to the right side.

[0041] The cross-sectional shape of each of the reaction vessel 11 and the conveying mechanism 13 in a plane perpendicular to the axis of the conveying mechanism 13 may be a shape having a combination defined by a Reuleaux constant width figure. In this case, the cross-sectional shape of the protrusion 131 of the conveying mechanism 13 may be a shape obtained by combining a plurality of arcs corresponding to the Reuleaux constant width figure. For example, in the case where the cross-sectional shape of the reaction vessel 11 is circular, the cross-sectional shape of the conveying mechanism 13 may be a Reuleaux constant width figure consisting of three arcs.

[0042] Figure 1 The shape of the protrusion 131 shown is only an example, and the shape of the protrusion 131 is not limited to this shape. The protrusion 131 may have different shapes for each region in the reaction vessel 11. For example, the pitch of the spiral of the protrusion 131 may be changed for each region in the reaction vessel 11. The spiral shape of the protrusion 131 is not necessarily a single spiral, but may be a double spiral or a multi-spiral. The protrusion 131 may include a portion that does not have a spiral shape. Therefore, the reaction device 10 can set the moving speed, behavior during movement, etc. of the object present in the reaction vessel 11 for each region. The conveying mechanism 13 not only has the function of conveying the object in the reaction vessel 11, but also has at least one of the functions of stirring, mixing, kneading, and crushing.

[0043] The temperature control area 12 includes a temperature control device, ie, a heating device or a cooling device, and controls the temperature of the reaction container 11 at a predetermined position in a middle portion provided between the supply port 18 and the delivery port 19 . Figure 1 The temperature control zone 12 shown comprises a heating device positioned at the middle part of the reaction vessel 11, and this heating device surrounds the periphery of the reaction vessel 11 with a cylindrical shape. The example of the heating device comprises any temperature-controllable heater, such as a sheath heater, a coil heater and a ceramic heater. The heating device, for example, performs heating in the range from ambient temperature to about 900 degrees. The temperature control zone 12 can set different temperatures to the region of the middle part of the reaction vessel 11 along the conveying direction of the conveying mechanism 13 described later. The temperature control zone 12 can control the temperature variation applied to the object to be processed R10 in the first fluid control zone 14 and the second fluid control zone 15 described later.

[0044] The temperature control area 12 may also include a temperature control unit for controlling the heating device or the cooling device. For example, the temperature control area 12 may include a temperature sensor for monitoring the temperature at a predetermined position in the reaction vessel 11, such as a thermocouple, a thermistor, a radiation thermometer, etc. In the case where the heating device has a principle of achieving heating by, for example, electric current, the reaction vessel 11 may be temperature controlled by monitoring the current value, the power value, etc.

[0045] The temperature control area 12 may have a configuration for achieving heating or cooling by circulating water, oil, etc. The temperature control area 12 may have a configuration for achieving cooling by using a Peltier component, a blower, etc. With the above configuration, the temperature control area 12 can set various temperature distributions in the reaction container 11 along the conveying direction of the conveying mechanism 13.

[0046] The first fluid control area 14 is arranged at a position between the supply port 18 and the second fluid control area 15 in the reaction container 11. The first fluid control area 14 has a structure that allows the first fluid to pass through the reaction container 11 in a predetermined area of ​​the middle part. The first fluid control area 14 includes, for example, a first fluid supply pipe 141, a first valve 142, and a first fluid discharge pipe 143. The first fluid supply pipe 141 supplies the first fluid to the reaction container 11. The first valve 142 adjusts the flow rate of the first fluid supplied from the first fluid supply pipe 141. The first fluid discharge pipe 143 discharges the fluid in the first fluid control area 14 to the outside of the reaction container 11.

[0047] Utilize the above-mentioned structure, reaction device 10 generates intermediate by making the first fluid reaction of object to be processed R10 and first fluid control area 14.In reaction device 10, drive conveying mechanism 13 to convey object to be processed R10, thereby further making object to be processed R10 contact with first fluid, therefore can promote the reaction caused by first fluid.Reaction device 10 discharges the reacted fluid to the outside of first fluid control area 14.The state and form of first fluid are not limited, as long as first fluid has fluidity.That is to say, first fluid can be gas, can be liquid, or can be slurry, in which powdery and granular materials etc. are dispersed in liquid.Can use one kind of composition, or can use two or more kinds of compositions, to constitute first fluid.That is to say, first fluid can be the mixed gas of hydrogen sulfide, hydrogen and argon.

[0048] The second fluid control area 15 is arranged in the reaction vessel 11 at a position between the first fluid control area 14 and the delivery port 19. The second fluid control area 15 has a structure for passing the second fluid through the reaction vessel 11 in an area different from the first fluid control area 14 in the middle part. The second fluid control area 15 includes, for example, a second fluid supply pipe 151, a second valve 152, and a second fluid discharge pipe 153. The second fluid supply pipe 151 supplies the second fluid to the reaction vessel 11. The second valve 152 regulates the flow rate of the second fluid supplied from the second fluid supply pipe 151. The second fluid discharge pipe 153 discharges the fluid in the second fluid control area 15 to the outside of the reaction vessel 11. The state and form of the second fluid are not limited as long as the second fluid has fluidity. That is, the second fluid can be a gas, a liquid, or a slurry in which powdery and granular materials are dispersed in a liquid. One component can be used, or two or more components can be used to constitute the second fluid. That is, the second fluid can be a mixed gas of hydrogen sulfide and nitrogen.

[0049] With the above configuration, the reaction device 10 generates a product R11 in the second fluid control region 15 by reacting the intermediate that has passed through the first fluid control region 14 with the second fluid. In the reaction device 10, the conveying mechanism 13 is driven to convey the intermediate, thereby further contacting the intermediate with the second fluid, thereby promoting the reaction caused by the second fluid. The reaction device 10 discharges the reacted fluid to the outside of the second fluid control region 15.

[0050] The reaction device 10 includes a control Figure 1 A control device for each component shown. Figure 2 4 is a functional block diagram of a control device 40 for the reaction device 10, to which the removal device 30 according to the embodiment is attached. Figure 2 As shown, the control device 40 includes a temperature control unit 41 , a first fluid control unit 42 , a second fluid control unit 43 , a third fluid control unit 44 , a conveying mechanism driving control unit 45 , an overall control unit 46 and a storage unit 47 .

[0051] Each of the components of the control device 40 can be implemented by dedicated hardware. Some or all of the components can be implemented by general or dedicated circuits, processors, etc., or a combination of the above. Some or all of the components of each device can be implemented by a combination of the above circuits, etc. and programs. For the processor, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (Field-Programmable Gate Array), etc. can be used.

[0052] The temperature control unit 41 controls the temperature of the reaction container 11 in the temperature control area 12. The temperature control unit 41 heats the reaction container 11, maintains a constant temperature of the reaction container 11, or cools the reaction container 11 through the temperature control device, for example, based on output from one or more temperature sensors (not shown) configured to control the temperature.

[0053] Figure 3 : is a diagram showing a state in which the take-out device according to Embodiment 1 is attached to the reaction container. The first fluid control unit 42 controls the flow of the first fluid in the first fluid control area 14. The first fluid control unit 42 includes control of the first valve 142 for pressurizing the first fluid. The second fluid control unit 43 controls the flow of the second fluid in the second fluid control area 15. The second fluid control unit 43 includes control of the second valve 152 for pressurizing the second fluid. The third fluid control unit 44 controls the flow of the third fluid in the third fluid control area 33 in the storage container 31, and the storage container 31 forms the take-out device 30 described later. The third fluid control unit 44 includes control of the inflow valve 332 that allows the third fluid to flow and control of the discharge valve 334. The take-out device 30 will be described in detail later.

[0054] The conveying mechanism drive control unit 45 controls the action of the drive device 17. The conveying mechanism drive control unit 45 drives the motor of the drive device 17 according to, for example, the output from a rotation sensor (not shown) that monitors the motor rotation speed. According to, for example, the temperature of the reaction container 11 sent from the temperature control unit 41, the overall control unit 46 can perform an overall action obtained by connecting the individual functions, such as giving an instruction for the action to the conveying mechanism drive control unit 45.

[0055] The storage unit 47 stores programs that enable the reaction device 10 to implement the above-mentioned various functions. The storage unit 47 may include a non-volatile memory, such as a flash memory, an SSD (Solid State Drive), etc. The storage unit 47 may also include an information input / output unit (not shown in the figure) that receives operations performed by a user, such as a button, a switch, a touch panel, etc. The information input / output unit may include a display device that presents information to the user, etc.

[0056] The configuration of the reaction device 10 is not limited to the above configuration. For example, two or more conveying mechanisms 13 may be provided. That is, the reaction device 10 may include a plurality of conveying mechanisms 13 provided in parallel. The reaction vessel 11 is not limited to the arrangement in which its central axis extends in the horizontal direction, and the reaction vessel 11 may be inclined at a predetermined angle relative to the horizontal direction. Although the reaction device 10 includes a first fluid control region 14 and a second fluid control region 15 in the middle portion, the reaction device 10 may also have a configuration that allows another fluid to pass through. That is, the reaction device 10 may include three or more fluid control regions. Note that less than two fluid control regions may be provided, or no fluid control region may be provided.

[0057] Unlike the above description, the conveying mechanism 13 does not need to be a screw, and other devices may be used as long as the device can convey the object to be processed from the supply port 18 to the delivery port 19 .

[0058] exist Figure 1 In the example shown, the reaction container 11 is arranged so that its central axis extends in the horizontal direction, and the reaction container 11 has a supply port 18 and a delivery port 19. A supply / drive unit 20 including a supply device 16 and a drive device 17 is detachably connected to the supply port 18 side, the supply device 16 supplies the object to be processed, and the drive device 17 drives the conveying mechanism 13.

[0059] The flange 21 is arranged at a position close to the supply port 18 side on the periphery of the reaction vessel 11. The flange 22 is arranged on the side facing the supply port 18 on the periphery of the supply / drive unit 20. A plurality of bolt holes (not shown in the figure) are arranged at each of the flange 21 and the flange 22 at predetermined intervals in the circumferential direction. The supply / drive unit 20 can be connected to the reaction vessel 11 by screwing bolts not shown in the figure into these bolt holes. It is desirable to also provide a sealing device, such as an O-ring made of rubber, between the flange 21 and the flange 22 to inhibit the intrusion of external air. However, the method for connecting the reaction vessel 11 and the supply / drive unit 20 to each other is not limited to this method.

[0060] The partition 23 is disposed between the flange 21 of the reaction vessel 11 and the temperature control area 12. The partition 23 is movable in a direction perpendicular to the central axis of the reaction vessel 11. By closing the partition 23, the space in the reaction vessel 11 is blocked from the space outside the reaction vessel 11. That is, by closing the partition 23, substances existing outside the reaction vessel 11 are prevented from invading the reaction vessel 11. Alternatively, by closing the partition 23, toxic substances existing in the reaction vessel 11 are prevented from being released to the outside of the reaction vessel 11.

[0061] The type of substance present outside the reaction vessel 11 is not limited, as long as the substance can react with the product etc. remaining in the reaction vessel 11 and thus produce a toxic substance. For example, the substance present outside the reaction vessel 11 may be ambient air, may be oxygen, or may be water vapor. For example, the substance present outside the reaction vessel 11 may be a liquid such as water, or may be a solid such as potassium permanganate. The removal device 30 according to the embodiment is used to remove the conveying mechanism 13 from such a reaction vessel 11. There is no particular limitation on the position at which the partition 23 is set, and the partition 23 may be set at a position different from the position between the flange 21 of the reaction vessel 11 and the temperature control area 12. Hereinafter, the removal device 30 according to the embodiment will be described.

[0062] <Implementation Method 1>

[0063] Will refer to Figure 3 The structure of the take-out device according to Embodiment 1 will be described. Figure 3 is a diagram showing a state in which the taking-out device 30 is attached to the reaction container 11. Figure 3 , the right side of the dot-dash line shows the configuration of the reaction device 10 in a state where the supply / drive unit 20 is removed, and the left side of the dot-dash line shows the configuration of the take-out device 30 .

[0064] like Figure 3 As shown, the removal device 30 includes a storage container 31, a connecting member 32, a third fluid control area 33 and a partition 34 as main components. The third fluid control area 33 includes a third fluid supply pipe 331, an inflow valve 332, a third fluid discharge pipe 333 and a discharge valve 334. The storage container 31 is airtightly connected to the supply port 18 side of the reaction container 11. Figure 3 In the example shown, the flange 37 is provided to the storage container 31 on the side facing the supply port 18 of the reaction container 11, and the seal portion 38 is provided to the storage container 31 on the opposite side. The cylindrical portion 35 is formed integrally with the flange 37 in such a manner as to extend toward the reaction container 11.

[0065] The flange 36 is arranged on the periphery of the cylindrical portion 35. The flange 36 has bolt holes at positions corresponding to the multiple bolt holes of the flange 21. By screwing bolts not shown in the figure into the bolt holes of the flange 21 and the bolt holes of the flange 36, the take-out device 30 can be connected to the reaction vessel 11. It is expected that a sealing device, such as an O-ring made of rubber, is also provided between the flange 21 and the flange 36 to suppress the intrusion of external air. However, the method for connecting the reaction vessel 11 and the take-out device 30 to each other is not limited to this method. The reaction vessel 11 and the take-out device 30 can be connected to each other by making at least a part of the reaction vessel 11 and the take-out device 30 contact each other, or can be connected to each other without having a part contacting each other. That is, the reaction vessel 11 and the take-out device 30 can be indirectly connected to each other by inserting a connection fixture, a cover member, etc. therebetween.

[0066] The storage container 31 is a component that stores the conveying mechanism 13 pulled out from the reaction container 11. It is desirable that the storage container 31 is composed of a material that allows the storage container 31 to contact the object to be processed or the product adhered to the conveying mechanism 13 to be stored in the storage container 31. For example, the storage container 31 may be made of a material having corrosion resistance, such as stainless steel or fluororesin. The storage container 31 may be made of the same material as the material used to form the reaction container 11. One side of the storage container 31 is connected to the flange 37 by welding or the like, and the other side of the storage container 31 is connected to the sealing portion 38 by welding or the like. The sealing portion 38 is provided in a manner to close one of the opening portions of the storage container 31.

[0067] The separator 34 is arranged on the cylindrical part 35 arranged between the flange 36 and the flange 37. The separator 34, for example, includes a valve member, which can move in a direction perpendicular to the axis of the conveying mechanism 13. The separator 34 switches the open state and the closed state between the reaction vessel 11 and the receiving container 31. By closing the separator 34, the space in the receiving container 31 is blocked from the external space by the separator 34 and the sealing portion 38. In other words, the separator 34 is a blocking mechanism, which blocks the space in the receiving container 31 of the receiving conveying mechanism 13 to prevent gas from invading from the outside. As long as the space in the receiving container 31 can be blocked to prevent gas from invading from the outside, various forms can be used to replace the separator 34. The example of the separator 34 includes a slide valve, a gate valve and other valves.

[0068] Preferably, the storage container 31 can be expanded / contracted according to the shape of the conveying mechanism 13. For example, the storage container 31 can change its length according to the length of the conveying mechanism 13. Figure 3In the example shown, for the storage container 31, a bellows that is extendable / contractable in the direction of the axis of the conveying mechanism 13 is used. The bellows is a hollow component having a cylindrical bellows shape. For the storage container 31, a component formed by a plurality of cylinders connected to each other in a telescopic form can be used. The storage container 31 can be an extendable / contractable elastic component such as a rubber tube.

[0069] The connecting member 32 connected to the conveying mechanism 13 is arranged inside the storage container 31. The connecting member 32 may be, for example, a clamping member including an opening / closing member, the conveying mechanism 13 is inserted into the opening / closing member, and a clamping bolt is provided to the opening / closing member. The conveying mechanism 13 is connected to the clamping member by tightening the clamping bolt when the conveying mechanism 13 is inserted into the opening / closing member. The connecting member 32 may be configured to be operable by a motor, compressed air, hydraulic pressure, etc. That is, the connecting member 32 may be a member powered. The connecting member 32 may use a clamping mechanism, etc., which clamps the conveying mechanism 13 by hydraulic pressure, etc., and fixes the conveying mechanism 13 by friction. Alternatively, the connecting member 32 may have a structure that can perform actions such as movement, extension / contraction, or rotation. For example, the connecting member 32 may have a structure in which the conveying mechanism 13 is inserted into the connecting member 32, and thereafter, the connecting member 32 is rotated so as to fix the conveying mechanism 13 to the connecting member 32. A component such as a hook or a chain may be placed between the conveying mechanism 13 and the connecting component 32. The connecting component 32 may include a control unit that receives a command signal for performing an action and controls the action. The command signal may be transmitted by connecting a control device that controls the reaction device to the removal device by wired communication using a cable or the like, or may be transmitted by wireless communication using radio waves or the like. The command signal may be transmitted by wired or wireless communication via a remote controller.

[0070] The connecting member 32 is connected to the sealing portion 38 on the side opposite to the reaction container 11 side of the storage container 31. Figure 3 As shown, when the storage container 31 is in a contracted state, the connecting member 32 is connected to the conveying mechanism 13. By bringing the storage container 31 from this state into an extended state, the connecting member 32 moves together with the storage container 31, and the conveying mechanism 13 is pulled out from the reaction container 11 and thus accommodated inside the storage container 31.

[0071] A third fluid supply pipe 331, an inflow valve 332, a third fluid discharge pipe 333, and a discharge valve 334 are included in a third fluid control area 33 in the storage container 31. The third fluid control area 33 allows the third fluid to pass through the storage container 31. The third fluid supply pipe 331 is provided between the partition 34 and the flange 37 of the cylindrical portion 35. The third fluid supply pipe 331 supplies the third fluid to the storage container 31. The inflow valve 332 adjusts the flow rate of the third fluid supplied from the third fluid supply pipe 331. The third fluid discharge pipe 333 discharges the fluid in the third fluid control area to the outside of the storage container 31. The third fluid discharge pipe 333 is provided with a discharge valve 334, which adjusts the discharge amount of the third fluid.

[0072] For example, the third fluid supply pipe 331 supplies an inert gas to the interior of the storage container 31 so that the interior of the storage container 31 enters an inert gas atmosphere. Examples of inert gases include argon, helium, nitrogen, and other gases. As described above, by placing the interior of the storage container 31 in an inert gas atmosphere, the conveying mechanism 13 can be safely removed from the reaction vessel 11 even when a highly reactive product remains adhered to the conveying mechanism 13. Instead of setting the interior of the storage container 31 to an inert gas atmosphere, the interior of the storage container 31 can be set to a vacuum atmosphere by reducing the pressure in the storage container 31, wherein the pressure is equal to or less than atmospheric pressure. In this case, the removal device 30 may include a decompression mechanism, such as a rotary pump, a mechanical booster pump, or other pumps, to reduce the pressure in the storage container 31. Such a configuration may be adopted, wherein, for example, the pressure in the storage container 31 is set to atmospheric pressure or less by a decompression mechanism, and then the inert gas is pressed from the third fluid supply pipe 331 to the storage container 31, and then the pressure in the storage container 31 is also set to atmospheric pressure or less by a decompression mechanism. If necessary, the above operation may be repeated. With this configuration, it is possible to preferably adjust the atmosphere in the storage container 31. The third fluid supply pipe 331 may include a detection device that detects the atmosphere in the storage container 31. Examples of the detection device include a pressure gauge, a hygrometer, an oxygen concentration meter, a hydrogen sulfide concentration meter, and the like.

[0073] Will refer to Figure 4 and Figures 5A to 5F A method for taking out the conveying mechanism 13 according to the embodiment will be described. Figure 4 : is a flowchart showing the taking-out method according to the first embodiment. Figures 5A to 5F 1 is a process diagram showing the taking-out method according to the first embodiment.

[0074] like Figure 4As shown, first, the interior of the storage container 31 is made into a vacuum state, or the interior of the storage container 31 is filled with an inert gas (S11). When the interior of the storage container 31 is filled with an inert gas, the control device 40 closes the partition 34, and opens the inlet valve 332 and the outlet valve 334 to supply the inert gas from the third fluid supply pipe 331. When the interior of the storage container 31 is in a vacuum atmosphere, the control device 40 closes the partition 34, and the pressure in the conveying mechanism 13 can be reduced by a decompression mechanism not shown in the figure. Therefore, when the storage container 31 is connected to the reaction container 11, even if the substance adhering to the conveying mechanism 13 has high reactivity, the substance can be prevented from contacting with the ambient air and causing a reaction. Therefore, the removal device 30 can be connected to the reaction container 11 more safely.

[0075] Next, the supply / drive unit 20 is removed while supplying the inert gas to the reaction container 11 (S12). For example, the control device opens the first valve 142 to supply the inert gas from the first fluid supply pipe 141 to the reaction container 11. At this time, the partition 23 is in an open state. Figure 5A The operating status at this time is shown in Figure 5A In the illustrated example, the supply / drive unit 20 is removed, resulting in a state in which the left side of the reaction container 11 is opened.

[0076] Then, the storage container 31 is airtightly connected to the reaction container 11 (S13). More specifically, the control device 40 opens the first valve 142, the discharge valve 334, and the inflow valve 332 to supply the inert gas from the first fluid supply pipe 141, and the storage container 31 is connected to the reaction container 11 that is in an open state due to the removal of the supply / drive unit 20. At this time, the partition 23 and the partition 34 are in an open state, and the inflow valve 332 is in a closed state. For example, the method for airtightly connecting the reaction container 11 and the storage container 31 to each other is performed by screwing a bolt into the bolt hole of the flange 21 and the bolt hole of the flange 36. Figure 5B The operating status at this time is shown in FIG. Figure 5BAs shown by the arrow pointing from the left to the right in the figure, the storage container 31 is connected from the left side of the reaction container 11. When the storage container 31 is connected, the part of the conveying mechanism 13 connected to the supply / drive unit 20 is inserted into the storage container 31. The method of airtightly connecting the reaction container 11 and the storage container 31 to each other is not limited to the above method, and other methods can also be used. As long as the reaction container 11 and the storage container 31 are connected airtightly, they may not have a part that contacts each other, and the reaction container 11 and the storage container 31 may be indirectly connected to each other by a clamp, a sleeve, etc. About the airtightness at the connection part between the reaction container 11 and the storage container 31, the airtightness can be confirmed by using, for example, a detection gas, such as nitrogen or helium. For example, when the detection gas is supplied to the reaction container 11 or the storage container 31, the airtightness can be confirmed by observing that the detection gas does not leak at the connection part between the reaction container 11 and the storage container 31.

[0077] As described above, in S11, the interior of the storage container 31 is in a vacuum state or a state filled with an inert gas, so even when the flow rate of the inert gas supplied from the first fluid supply pipe 141 is insufficient, the possibility of ambient air entering the reaction container 11 can be suppressed, and thus safety can be further improved. In the case where the inert gas supplied in S12 fills the interior of the storage container 31 and has a sufficient flow rate level, it is not necessary to provide the step in S11, wherein the sufficient flow rate level can prevent the substance adhering to the conveying mechanism 13 from reacting with the ambient air during the connection of the storage container 31. Thereafter, the storage container 31 is airtightly connected to the reaction container 11 (S13).

[0078] Then, in the storage container 31, the connecting member 32 is connected to the conveying mechanism 13 (S14). For example, in the case where a clamping member including an opening / closing member and a clamping bolt is used as the connecting member 32, the conveying mechanism 13 can be connected to the clamping member by inserting the conveying mechanism 13 into the opening / closing member and by tightening the clamping bolt. Figure 5C The operating status at this time is shown in FIG. Figure 5C As shown, when the conveying mechanism 13 is connected to the connecting member 32, the discharge valve 334 is in a closed state.

[0079] Then, the transport mechanism 13 is removed from the reaction container 11 by expanding the storage container 31 and moving the connecting member 32 (S15). Figure 5D The operating status at this time is shown in FIG. Figure 5DAs shown, by stretching the reaction vessel 11, the connecting member 32 moves in the direction indicated by the arrow pointing from the right to the left. By this movement of the connecting member 32, the conveying mechanism 13 is taken out from the reaction vessel 11. Thereafter, after the conveying mechanism 13 is accommodated in the accommodation container 31, the partition 34 is closed to hermetically seal the accommodation container 31 (S16). In addition, the partition 23 is placed in a closed state so that the space in the reaction vessel 11 is hermetically sealed. Therefore, the product in the reaction vessel 11 can be prevented from being exposed to ambient air.

[0080] Then, the removal device 30 is removed from the reaction device 10 ( S17 ). For example, by removing the bolts screwed into the bolt holes in the flange 21 and the bolt holes in the flange 36 , the connection between the reaction container 11 and the storage container 31 is released. Fig. 5F As described above, according to Embodiment 1, the conveying mechanism 13 can be housed in the airtight and closed space in the housing container 31 without exposing the conveying mechanism 13 to the ambient air. Therefore, even when a substance having high reactivity remains adhered to the conveying mechanism 13, the conveying mechanism 13 can be handled safely.

[0081] like Fig. 5F As shown, the conveying mechanism 13 can be cleaned in a state of being accommodated in the accommodation container 31. That is, the accommodation container 31 can also be used as a cleaning container for cleaning the conveying mechanism 13. For example, in a case where the sulfur-containing compound remains adhered to the conveying mechanism 13, water can be supplied to the interior of the accommodation container 31 while the conveying mechanism 13 is accommodated in the accommodation container 31. Hydrogen sulfide generated due to the reaction between the water and the sulfur-containing compound can be discharged through the third fluid discharge pipe 333.

[0082] As described above, the connection member 32 connected to the conveying mechanism 13 may be provided in a rotatable manner. That is, the connection member 32 has a function as a rotating mechanism capable of rotating the conveying mechanism 13. For example, by the action of the control unit, the connection member 32 may rotate the conveying mechanism 13 connected to the connection member 32. When cleaning the conveying mechanism 13, by rotating the connection member 32 in the storage container 31, the conveying mechanism 13 connected to the connection member 32 may be rotated. As described above, during the cleaning of the conveying mechanism 13, by rotating the connection member 32, the cleaning may be promoted.

[0083] After the generation of hydrogen sulfide is stopped, water as a cleaning solution is discharged from the inside of the storage container 31, and the conveying mechanism 13 can be dried by supplying a dry inert gas from the third fluid supply pipe 331. Therefore, the storage container 31 may include a discharge portion for discharging the cleaning solution for cleaning. The cleaned conveying mechanism 13 can be taken out of the storage container 31, or can be attached to the reaction device 10 in a state of being accommodated in the storage container 31. As described above, the removal device 30 of the present embodiment is not only used to remove the conveying mechanism 13, but can also be applied to various other processes, including cleaning the conveying mechanism 13.

[0084] The taking-out device 30 may further include various detection devices for monitoring the state in the storage container 31. Examples of the various detection devices include a thermometer, a hygrometer, a gas concentration meter capable of detecting hydrogen sulfide, etc., a photographic device for observing the inside of the storage container 31, and the like.

[0085] The above-mentioned conveying mechanism 13 ranges from a light conveying mechanism having a length of about 20 to 30 cm to a conveying mechanism having a length of several meters and a weight of several hundred kilograms. Therefore, when the storage container 31 is extended, it is preferable to support the storage container 31. In the case where the lower side of the storage container 31 is supported by a supporting member, by extending the storage container 31 with a heavy conveying machine such as a crane, the connecting member 32 can be moved. That is, the heavy conveying machine is a driving mechanism that moves the connecting member. For example, in Figure 3 In the embodiment, a support member (not shown) for supporting the storage container 31 may be provided between the flange 37 of the cylindrical portion 35 and the partition 34. The storage container 31 may be extended by moving the crane to the left while the vicinity of the discharge valve 334 disposed on the left side of the sealing portion 38 is supported by the crane. Therefore, when the conveying mechanism 13 is pulled out from the reaction container 11, the conveying mechanism 13 that tends to fall may be supported.

[0086] The heavy machinery for conveying is not limited to a crane, and may be a conveying vehicle including wheels, etc., or may be a winch that winds up the wire via a pulley. The control unit of the heavy machinery for conveying may be synchronized with the control unit provided to the take-out device 30 or with the control device 40 for the reaction device 10, and thus activated by the controller for the reaction device 10 or the controller for the take-out device 30. When the conveying mechanism 13 is light in weight, the storage container 31 may be extended / contracted by manual intervention.

[0087] In Embodiment 1, the central axis of the reaction vessel 11 having a cylindrical shape is aligned with the rotation axis of the conveying mechanism 13, and the example in which the storage container 31 stretches / contracts along the axis is described. However, the configuration is not limited to this configuration. The storage container 31 can stretch / contract according to the shape of the conveying mechanism 13. For example, in the case where the reaction vessel 11 has a bend and the conveying mechanism 13 is bent in accordance with the shape of the reaction vessel 11, the storage container 31 can stretch / contract according to the bend of the conveying mechanism 13. The cross-sectional shape of the reaction vessel 11 is not limited to a circle or an ellipse. The cross-sectional shape of the reaction vessel 11 may be a quadrilateral, such as a square or a rectangle, or may be a polygon other than a quadrilateral.

[0088] <Implementation Method 2>

[0089] Figure 6 2 is a diagram showing a state in which a take-out device according to Embodiment 2 is attached to a reaction device. Embodiment 2 is different from Embodiment 1 in that the storage container 31 is not expandable / contractable. Figure 6 As shown, the storage container 31A is a cylindrical member having a length comparable to that of the conveying mechanism 13. The storage container 31A can be made of a material that allows the storage container 31A to contact the object to be processed or the product adhered to the conveying mechanism 13 to be stored in the storage container 31A, for example, it can be made of a corrosion-resistant material such as stainless steel or fluororesin. The cross-sectional shape of the storage container 31A is not limited to a circular or elliptical shape. The cross-sectional shape of the storage container 31A can be a quadrilateral, such as a square or a rectangle, or a polygon other than a quadrilateral.

[0090] exist Figure 6 In the example shown, in the storage container 31A, the connection member 32 is provided so as to be movable from the right side to the left side of the storage container 31A. The conveying mechanism 13 is connected to the connection member 32, wherein the connection member 32 is located on the right side in the storage container 31A. After the conveying mechanism 13 and the connection member 32 are connected to each other, the conveying mechanism 13 can be pulled out from the reaction container 11 by moving the connection member 32 together with the conveying mechanism 13 toward the left side in the storage container 31.

[0091] The present invention is not limited to the above-mentioned embodiment and can be appropriately changed without departing from the gist of the present invention. In the above-mentioned example, the removal device 30 is connected after the supply / drive unit 20 is removed. However, the configuration is not limited to this configuration. For example, Figure 7As shown, a structure may be adopted in which a removable cover 50 is provided to the reaction container 11 on the side where the delivery port 19 is provided, and the storage container 31 is connected to the reaction container 11 from which the cover 50 is removed. More specifically, the cover 50, the partition 51, and the bearing 52 are provided on the delivery port 19 side of the reaction container 11. The stopper 53 is provided on the cover 50 side of the conveying mechanism 13. The conveying mechanism 13 is inserted so that the stopper 53 contacts the bearing 52, and the conveying mechanism 13 is supported in a rotatable manner. The partition 51 is provided between the cover 50 and the bearing 52. In this case, Figure 8 In the embodiment, the storage container 31 is connected to the right side of the reaction container 11, and the direction in which the conveying mechanism 13 is pulled out is the right direction. Fig. 9 As shown, a stopper 54 may be provided on the outer periphery of the bearing 52. The stopper 54 includes a protrusion 55, which is assembled in a recessed portion not shown in the figure and provided on the inner periphery of the reaction vessel 11. The stopper 54 prevents the bearing 52 from rotating with the rotation of the conveying mechanism 13. The stopper 54 may have an involute spline shape. When the connection between the receiving container 31 and the reaction container 11 is released after the conveying mechanism 13 is accommodated in the receiving container 31, the partition 51 may be set to a closed state.
