[0007] However, when using a conveying mechanism, such as a screw to convey a processed object with a fine particle size, there is a risk of the processed object agglomerating or solidifying due to stagnation in the gap in the structure of the conveying mechanism or in the space where the conveying force is not directly reached. The occurrence of this state may cause the quality of the product manufactured by the reaction system to change. Alternatively, when the conveying speed of the conveying mechanism is relatively low, the reaction rate of the aggregated processed object may decrease, and may cause the efficiency of the reaction system to decrease.

[0019] Hereinafter, although the present invention will be described by the embodiments of the present invention, the present invention set forth in the claims is not limited to the following embodiments. In addition, not all the components described in the embodiments are essential as solutions to the problems. In the following description and drawings, for the sake of clarity, omissions and deletions are made where appropriate. In each of the drawings, the same elements are represented by the same reference numerals, and repeated descriptions are omitted as needed.

[0020] <First Embodiment>

[0021] Will refer to Figure 1 A first embodiment will be described. Figure 1 It is an overall design diagram of the reaction system 1 according to the first embodiment. Figure 1The reaction system 1 shown manufactures a product by subjecting the processed object to a predetermined treatment. The product manufactured by the reaction system 1 is not particularly limited, and examples of the product include battery components, such as solid electrolytes and positive electrode active materials used in all-solid-state lithium-ion secondary batteries. The predetermined treatment is not particularly limited, as long as the predetermined treatment is a means used in the process of turning the processed object into a product, and an example of the predetermined treatment is a temperature change, such as heating or cooling. For example, the predetermined treatment may include stress transfer, such as stirring, mixing, kneading or crushing. Alternatively, the predetermined treatment may be, for example, a reaction involving the transfer of electrons and free radicals. Alternatively, the predetermined treatment may include, for example, contact with a catalyst. The reaction system 1 is mainly composed of a reactor 100 and a conveying device 141.

[0022] The reaction furnace 100 is mainly composed of a supply port 110, a delivery port 120, and a cylinder 101. In addition, the reaction furnace 100 includes a conveying auxiliary material discharge port 130 and a temperature control device 150.

[0023] The terms "upstream" and "downstream" will be used in the present disclosure hereinafter, and the upstream and downstream are defined as follows. At point A, which is any position along the route from the supply port 110 to the delivery port 120 of the reactor 100, the position close to the supply port 110 as viewed from point A will be defined as the upstream position, and the position close to the delivery port 120 as viewed from point A will be defined as the downstream position. In addition, the upstream side refers to the upstream direction as viewed from point A, and the downstream side refers to the downstream direction as viewed from point A. In addition, outside the supply port 110 and the delivery port 120, the above-mentioned "upstream" direction and "downstream" direction are also defined similarly. For example, when an object flowing from the supply port 110 to the delivery port 120 flows farther outside the delivery port 120, the object can be described as flowing downstream outside the delivery port 120.

[0024] The supply port 110 is an opening provided on the barrel 101, and receives the processed object 10A and the conveying auxiliary material 20 respectively. The supply port 110 according to the present embodiment includes a first supply port 111 and a second supply port 112. The first supply port 111 receives the processed object 10A. The second supply port 112 receives the conveying auxiliary material 20. Note that the supply port 110 may be designed so that the processed object 10A and the conveying auxiliary material 20 are supplied to the supply port 110 in a mixed state. Once the supply port 110 receives the processed object 10A and the conveying auxiliary material 20, the supply port 110 supplies the processed object 10A and the conveying auxiliary material 20 to the barrel 101.

[0025] The conveying auxiliary material 20 is used to convey the processed material 10A without stagnation, and its example is a granular material, such as sand or spherical beads. The conveying auxiliary material 20 can have any shape, and the conveying auxiliary material 20 is preferably spherical. In addition, the material of the conveying auxiliary material 20 is not particularly limited, and the conveying auxiliary material 20 is, for example, a solid that can be mixed with the processed material 10A and separated therefrom, such as silica sand, ceramics, glass, carbon, activated carbon or metal. Desirably, the particle size of the conveying auxiliary material 20 is different from the particle size of the processed material 10A, so that the conveying auxiliary material 20 and the resultant 10B can be easily separated. There is no particular restriction on the measuring means of the above-mentioned particle size, for example, the average value (average diameter) of the particle size distribution can be measured by a laser diffraction / scattering particle size distribution measuring device (for example, LA960 manufactured by HORIBA, Ltd.). Therefore, the reaction system 1 can convey the mixture of the processed material 10A and the conveying auxiliary material 20, so that the aggregation and stagnation of the processed material 10A can be suppressed.

[0026] The delivery port 120 delivers the manufactured product 10B. More specifically, the delivery port 120 has a plurality of small holes, which are larger than the particle size of the product 10B and smaller than the particle size of the conveying auxiliary material 20, thereby allowing the product 10B to pass through a plurality of holes, while not allowing the conveying auxiliary material 20 to pass through a plurality of holes. Therefore, the delivery port 120 separates and extracts the product 10B from the mixture, and the extracted product 10B is delivered from the delivery port 120. In other words, in this case, the cylinder 101 accommodates the conveying auxiliary material 20 whose particle size is larger than the particle size of the product 10B. The conveying auxiliary material 20 remaining in the cylinder 101 is transported downstream from the delivery port 120 and discharged from the conveying auxiliary material discharge port 130 arranged on the downstream side of the delivery port 120. The plurality of holes of the delivery port 120 are, for example, a screen (net), and can be vibrated by being subjected to vibration (e.g., 50 to 500 Hz) of a vibration device not shown.

[0027] The barrel 101 accommodates the mixture between the supply port 110 and the delivery port 120. The barrel 101 includes a processing space, which is a space for manufacturing a product 10B from the processed object 10A. In the processing space, the reaction system 1 manufactures the product 10B by performing a predetermined process on the mixture of the processed object 10A and the conveying auxiliary material 20. The barrel 101 is covered by a temperature control device 150 in the middle part, and is designed so that the interior of the reaction furnace 100 can be heated or cooled.

[0028] The mixture refers to the mixed processed product 10A and the conveying auxiliary material 20. The mixture also refers to a mixture of the product 10B and the conveying auxiliary material 20 when the reaction of the processed product 10A proceeds and the processed product 10A becomes the product 10B. In addition, naturally, the mixture also includes the mixed processed product 10A, the product 10B and the conveying auxiliary material 20.

[0029] The conveyance auxiliary material discharge port 130 is an opening provided on the cylinder 101 to discharge the conveyance auxiliary material 20. The conveyance auxiliary material discharge port 130 is located on the downstream side of the delivery port 120, and discharges the conveyance auxiliary material 20 from which the product 10B has been separated.

[0030] The temperature control device 150 includes a heating device or a cooling device, and controls the temperature inside the reaction furnace 100, or in other words, controls the temperature inside the barrel 101. The temperature control device 150 includes a heating device around the barrel 101 in the middle part of the reaction furnace 100. For example, the heating device includes any heater capable of controlling the temperature, such as a sheath heater, a coil heater or a ceramic heater. For example, the heating device implements heating in the range from room temperature to about 1000 degrees. The temperature control device 150 can set different temperatures for each region in the middle part of the reaction furnace 100 in the conveying direction of the conveying device 141. The temperature control device 150 can set different temperatures for each region in the up and down direction (minor axis direction) of the reaction furnace 100. For example, the temperature control device 150 controls the temperature in the range of 100 to 1000 degrees Celsius, preferably controls it at more than 300 degrees Celsius, and more preferably controls it at more than 500 degrees Celsius.

[0031] The driving device 140 includes a motor and a driving force transmitting portion, and drives the conveying device 141 , wherein the driving force transmitting portion cooperates with a driving shaft protruding from the motor. Figure 1 The conveying device 141 shown is, for example, a screw extending from one end to the other end of the barrel 101. In this case, the conveying device 141 conveys the mixture using a screw rotating around an axis set along the conveying direction of the mixture. Note that there may be one screw, or more than two screws.

[0032] The conveying device 141 conveys the mixture from the supply port 110 to the delivery port 120 in the barrel 101. In the conveying device 141, the rotating shaft extending along the barrel 101 is rotated by the driving device 140. For example, the driving device 140 can control the driving direction and driving speed of the conveying device 141. The shape and form of the conveying device 141 are not particularly limited. For example, the conveying device 141 is not limited to the above-mentioned screw, and can be a conveyor belt or a rotating drum body. The conveying device 141 can be a shaking device that shakes the barrel 101. The conveying device 141 can be a tilting device that tilts the barrel 101.

[0033] For example, the components constituting the reaction furnace 100 may be formed of alloys, ceramics, carbon, and composite materials containing two or more of these materials. The alloy is a metal composition including at least one of the following alloy elements as a component: nickel, cobalt, chromium, molybdenum, tungsten, tantalum, titanium, iron, copper, aluminum, silicon, boron, and carbon. Ceramic is a ceramic composition, which is: an oxide such as aluminum oxide or zirconium oxide; a carbide such as silicon carbide or titanium carbide; a nitride such as silicon nitride or titanium nitride; or a boride such as chromium boride. In addition, carbon is a carbon composition, such as crystalline graphite or fiber-reinforced graphite. For example, the reaction furnace 100 may be composed of a component containing at least an alloy, a ceramic, or carbon as a material for its interior.

[0034] Although not shown, the reactor 100 may have a fluid supply port in the middle portion to receive the reaction fluid required for the manufacturing process of the process object 10A. Similarly, the reactor 100 may have a fluid discharge port in the middle portion to discharge the reaction fluid or the fluid generated after the reaction.

[0035] The components of the reaction system 1 have been described above, and the reaction system 1 may further include a control device for controlling the above components. For example, the control device includes a calculation unit, such as a central processing unit (CPU), a graphics processing unit (GPU) or a microcontroller unit (MCU). In addition, the control device includes: a storage device, such as a dynamic random access memory (DRAM) or a flash memory; an interface that can communicatively connect the various components; and other peripheral circuits.

[0036] The reaction system 1 may be designed to supply the conveyance auxiliary material 20 having a particle size smaller than that of the product 10B. In this case, for example, the reaction system 1 has a plurality of holes having a particle size larger than that of the conveyance auxiliary material 20 and smaller than that of the product 10B on the upstream side of the delivery port 120, and the plurality of holes are made to allow the conveyance auxiliary material 20 to pass through but not allow the conveyance auxiliary material 20 to pass through. Furthermore, in this case, the reaction system 1 has a bypass path, and while guiding the product 10B to the delivery port 120, the bypass path guides the conveyance auxiliary material 20 having passed through the plurality of holes to the downstream side of the delivery port 120. Therefore, the delivery port 120 separates and extracts the product 10B from the mixture, and the extracted product 10B is delivered from the delivery port 120.

[0037] Next, we will refer to Figure 2 The processing performed by the reaction system 1 will be described. Figure 2It is a flowchart of the method for producing a product according to the first embodiment. Figure 2 A flowchart may also be described as showing processing performed by a control device (not shown). Figure 2 The flowchart shown can also be described as an operating procedure performed by a user operating the reaction system 1 .

[0038] First, the reaction system 1 operates the temperature control device 150 to adjust the temperature of the reaction furnace 100 (step S10 ).

[0039] Next, the reaction system 1 drives the driving device 140 to start driving the conveying device 141 (step S20 ).

[0040] Next, the reaction system 1 supplies the conveying auxiliary material 20 to the reaction furnace 100 (step S30). In addition, the reaction system 1 supplies the processed object 10A to the reaction furnace 100 (step S40). Note that steps S30 and S40 can be performed in reverse order or simultaneously. In other words, at this time, as a supply process, the reaction system 1 supplies the processed object 10A and the conveying auxiliary material 20 to the reaction furnace 100.

[0041] Next, as a transport step, the reaction system 1 transports the mixture of the processed object 10A and the transport auxiliary material 20 toward the delivery port 120 using the transport device 141 (step S50 ).

[0042] Next, as a delivery step, the reaction system 1 delivers the product 10B from the delivery port 120 (step S60 ).

[0043] The above is a description of the method for producing a product performed by the reaction system 1. The reaction system 1 can continuously produce the product 10B by continuously performing the above-mentioned procedures. In other words, the reaction system 1 supplies the transport auxiliary material 20 together with the processed material 10A, and reacts the processed material 10A while transporting the mixture of the transport auxiliary material 20 and the processed material 10A. Therefore, the reaction system 1 can appropriately and continuously produce the product 10B from the processed material 10A.

[0044] The first embodiment is described above. In the reaction furnace 100, for example, Figure 1As shown, there is a gap with a distance of D1 between the conveyor 141 and the cylinder 101. The reason for the distance D1 is, for example, to prevent the conveyor 141 and the reactor 100 from contacting each other. If the conveyor 141 and the reactor 100 contact each other, abrasion powder can be generated at the contact portion. Abrasion powder contaminates the product, so it is undesirable. In addition, in particular, when the temperature in the reactor 100 exceeds 500 degrees Celsius, there is a possibility that strong heat burning adhesion occurs at the contact portion and the conveyor 141 will stop working. The distance D1 is greater than the particle size of the processed object 10A or the product 10B. Therefore, if only the processed object 10A is received and conveyed, there is a possibility that the processed object 10A stagnates in the gap. In view of this, the reactor 100 is supplied with a conveying auxiliary material 20 whose particle size is greater than the particle size of the processed object 10A, and conveys the mixture mixed by the processed object 10A and the conveying auxiliary material 20. Due to this design, the reaction system 1 can smoothly convey the processed object 10A and manufacture the product 10B.

[0045] The state of the mixture of the processed object 10A and the conveying auxiliary material 20 conveyed by the conveying device 141 is called a "moving bed". In the moving bed, the processed object 10A is conveyed by the conveying device 141 in a state mixed with the conveying auxiliary material 20, and reacts. In other words, by generating a moving bed, the reaction system 1 reacts the processed object 10A without stagnation. In this case, it can be considered that the moving speed of the conveying auxiliary material 20 in the conveying direction of the moving bed is equal to the conveying speed of the processed object 10A in the same direction. In other words, in the reaction system 1, the moving speed of the conveying auxiliary material 20 is set so that the reaction of the processed object 10A is completed within a preset period. Therefore, it is expected that the moving speed of the conveying auxiliary material 20 is slow enough without damaging the productivity of the reaction system 1 for manufacturing the product 10B, and for example, it is less than 10 meters / hour. More preferably, the moving speed of the conveying auxiliary material 20 is less than 3 meters / hour, and even more preferably less than 1 meter / hour. As described above, according to the present embodiment, a reaction system that can efficiently manufacture a product can be provided.

[0046] <Second Embodiment>

[0047] Next, a second embodiment will be described. Figure 3 2 is an overall design diagram of the reaction system 2 according to the second embodiment. The reaction system 2 according to the second embodiment has a function of circulating the transport auxiliary material 20 discharged from the transport auxiliary material discharge port 130. In addition, the reaction system 2 performs a preset recovery process on the transport auxiliary material 20 after being separated from the product 10B.

[0048] The reaction system 2 according to the present embodiment includes a circulation device 200 located on the downstream side of the delivery port 120. The circulation device 200 receives the transport auxiliary material 20 separated from the product 10B from the transport auxiliary material discharge port 130, and circulates the received transport auxiliary material discharge port 130 to the supply port 110. The circulation device 200 includes a pressure feeding device 201 and an auxiliary material delivery pipe 202.

[0049] For example, the pressure feeding device 201 is a pump provided in the auxiliary material conveying pipe 202, and pressure feeds air and the conveying auxiliary material 20 in a direction from the conveying auxiliary material discharge port 130 toward the supply port 110. The auxiliary material conveying pipe 202 is a pipe that connects the conveying auxiliary material discharge port 130 and the supply port 110 to each other and enables the conveying auxiliary material 20 to pass through. Since it is designed in this way, the reaction system 2 can reuse the conveying auxiliary material 20. Therefore, the reaction system 2 can efficiently produce the product 10B.

[0050] Furthermore, the reaction system 2 according to the present embodiment has a function of performing a predetermined process on the transport auxiliary material 20 after being separated from the product 10B. In the reaction system 2 , the circulation device 200 further includes a medium receiving portion 210 and a contact portion 220 .

[0051] The medium receiving part 210 receives a recovery medium, which contacts the conveying auxiliary material 20 after being separated from the product 10B. Depending on the application, various substances can be used as the recovery medium. For example, the recovery medium can be a cleaning medium for cleaning the conveying auxiliary material 20. The form of the cleaning medium is not particularly limited. In other words, the cleaning medium can be a gas, a liquid, a solid or a supercritical fluid. The cleaning medium can be a mixture of at least two of the above. The cleaning medium is, for example, water vapor. The cleaning medium is, for example, an organic solvent, such as alcohol. The cleaning medium is, for example, a sublimable solid, such as naphthalene. The medium receiving part 210 is arranged on the downstream side of the delivery port 120. The medium receiving part 210 is connected to the recovery medium injection pipe 211 and receives the recovery medium supplied to the reactor 100 through the first valve 212.

[0052] The contact portion 220 brings the recovery medium into contact with the conveyance auxiliary material 20. The contact portion 220 is a space provided on the downstream side of the delivery port 120 and the upstream side of the conveyance auxiliary material discharge port 130, and the conveyance auxiliary material 20 and the recovery medium are in contact with each other in the space. After the conveyance auxiliary material 20 and the recovery medium are in contact with each other in the contact portion 220, the conveyance auxiliary material 20 is discharged from the conveyance auxiliary material discharge port 130.

[0053] The circulation device 200 further includes a medium discharge part 230. In the circulation device 200, the medium receiving part 210 receives a recovery medium for cleaning the conveyance auxiliary material 20. In this case, the medium discharge part 230 discharges the recovery medium after contacting the conveyance auxiliary material 20 to the outside of the reaction furnace 100. The medium discharge part 230 is connected to the recovery medium discharge pipe 231, and discharges the recovery medium to the outside of the reaction furnace 100 through the second valve 232. Since it is designed in this way, the reaction system 2 can circulate the conveyance auxiliary material 20 appropriately.

[0054] The transport auxiliary material 20 received by the reaction furnace 100 may be a catalyst that facilitates the reaction of the processed object 10A, and may contain a metal element. In this case, the circulation device 200 receives a recovery medium containing a non-metallic element for reducing the transport auxiliary material 20. More specifically, the transport auxiliary material 20 may contain a metal such as iron, nickel, or cobalt. In this case, for example, the recovery medium may be a gas containing hydrogen.

[0055] Next, Figure 4 It is a flowchart of the method for producing a product according to the second embodiment. Figure 4 The flowchart shown is similar to Figure 2 The flowchart shown differs in that Figure 4 The illustrated flowchart includes a step S31 after the step S30 .

[0056] In step S31 , the reaction system 2 starts driving the circulation device 200 . Therefore, the circulation device 200 performs recovery processing on the transport auxiliary material 20 supplied to the reaction furnace 100 , and supplies the recovered transport auxiliary material 20 again to the supply port 110 through the transport auxiliary material discharge port 130 .

[0057] As described above, the reaction system 2 efficiently generates a moving bed by appropriately circulating the transport auxiliary material 20. Therefore, according to the present embodiment, a reaction system and the like capable of efficiently producing a product can be provided.

[0058] <Third Embodiment>

[0059] Subsequently, a third embodiment will be described. Figure 5 2 is an overall design diagram of a reaction system 3 according to a third embodiment. The reaction system 3 according to this embodiment is different from the above-mentioned embodiment in that the reaction system 3 further includes a fluidized bed generating device 300 .

[0060] The fluidized bed generating device 300 improves the fluidity of the mixture conveyed by the conveying device 141 by spouting a stirring fluid to the mixture. In this case, the mixture in a state in which the fluidity is improved by the stirring fluid is also referred to as a "fluidized bed". The fluidized bed generating device 300 includes a third valve 301, a fluid conveying pipe 302, and a spouting port 303 as main components. By supplying the stirring fluid to the spouting port 303, the fluidized bed generating device 300 improves the fluidity of the moving bed and generates a fluidized bed.

[0061] Fluid delivery pipe 302 receives stirring fluid via the 3rd valve 301, and the stirring fluid received is supplied to spouting port 303.Stirring fluid is the fluid for stirring mixture, and more specifically, for example, stirring fluid is inert nitrogen.When product 10B is manufactured by processed object 10A, when processed object 10A must be contacted with reaction fluid, reaction fluid can be adopted as stirring fluid.Therefore, reaction system 3 can accelerate reaction by reaction fluid, and improve the flowability of mixture simultaneously.

[0062] The spout 303 is an opening provided on the cylinder 101 of the reaction furnace 100. In other words, the reaction furnace 100 includes the spout 303 for spouting the stirring fluid to the mixture. For example, the spout 303 is provided in an area located at the lower part of the cylinder 101 and where the mixture transported by the transport device 141 exists. Therefore, the stirring fluid spouted from the spout 303 directly contacts the mixture. Therefore, the mixture is stirred and the fluidity is improved.

[0063] The conveying device 141 according to the present embodiment conveys the mixture in contact with the stirring fluid. In other words, the reaction system 3 conveys the mixture in a state where the mixture has been stirred by the stirring fluid and the fluidity of the mixture has been improved.

[0064] Preferably, there are a plurality of ejection ports 303 on the cylinder 101 along the conveying direction of the mixture. In this case, the plurality of ejection ports 303 may be arranged linearly from the upstream side toward the downstream side, for example. Alternatively, the plurality of ejection ports 303 may be arranged spirally on the cylinder 101, for example. In the reaction system 3 according to the present embodiment, the particle size of the processed object 10A is smaller than the particle size of the conveying auxiliary material 20. For example, the particle size of the processed object 10A is less than 0.05 mm. In addition, for example, the particle size of the conveying auxiliary material 20 is more than 0.3 mm, preferably more than 0.5 mm, and more preferably more than 1 mm. In this case, preferably, the opening size of the ejection port 303 is larger than the particle size of the processed object 10A and smaller than the particle size of the conveying auxiliary material 20. In other words, for example, the opening size of the ejection port 303 is more than 0.1 mm.

[0065] Figure 63 is a diagram showing details of the fluidized bed generating device 300. The fluidized bed generating device 300 further includes a regulator 310. The regulator 310 regulates at least one of the flow rate, flow velocity, or temperature of the stirring fluid supplied to the reactor 100. To achieve this function, the regulator 310 includes, for example, a pressure pump, a temperature regulator, and the like.

[0066] In addition, if Figure 6 As shown, the fluid delivery tube 302 may have a varying tube thickness at the ejection port 303 . Figure 6 The diameter of the fluid delivery pipe 302 shown is L2, and the diameter of the spout 303 is L1, which is smaller than the diameter L2. Since the cross-sectional area of ​​the spout 303 is smaller than the cross-sectional area of ​​the fluid delivery pipe 302, the flow rate of the stirring fluid in the spout 303 increases. Therefore, even when the particle size of the processed object 10A is smaller than the opening of the spout 303 as described above, the fluidized bed generating device 300 can prevent the processed object 10A from stagnating at the spout 303 or prevent the processed object 10A from entering the spout 303, and can appropriately generate a fluidized bed. Note that the diameter L1 of the spout 303 may be smaller than the particle size of the processed object 10A.

[0067] In addition, if Figure 6 As shown, the fluid delivery pipe 302 can be adjusted to obtain optimal fluidity by changing the angle of a portion of the spout 303. The fluidized bed generating device 300 may include a third valve 301, a fluid delivery pipe 302, and a spout 303 for a plurality of different systems. Therefore, the fluidized bed generating device 300 may set the angle of a portion of the spout 303 or set different flow rates for each different system. In this case, the adjusting unit 310 may be responsible for switching the system and allocating the flow rate. In other words, in this case, the adjusting unit 310 may also adjust the spouting direction of the stirring fluid.

[0068] Figure 7 It is a flowchart of the method for producing a product according to the third embodiment. Figure 7 The flowchart shown is similar to Figure 4 The flowchart shown differs in that Figure 7 The illustrated flowchart includes step S21 after step S20 .

[0069] In step S21 , the reaction system 3 starts ejecting the stirring fluid (step S31 ). The reaction system 3 prevents the processed material 10A or the transport auxiliary material 20 from entering the ejection port 303 by ejecting the stirring fluid from the ejection port 303 before the processed material 10A or the transport auxiliary material 20 is supplied to the cylinder 101 .

[0070] In this case, in step S50 (transportation step), the reaction system 3 transports the mixture stirred by the ejected stirring fluid. In other words, the reaction system 3 generates a moving bed and a fluidized bed, and accelerates the reaction of the processed material 10A in the presence of a mixture of the moving bed and the fluidized bed. Therefore, according to this embodiment, a reaction system capable of efficiently producing a product can be provided.

[0071] Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above-described embodiments. Within the scope of the present invention, those skilled in the art can make various modifications to the design and details of the present invention.
