Description

[Technical field]

[0001] The present invention relates to a reactor. [Background technology]

[0002] There are reactors for continuously producing desired products by providing a specific atmosphere to raw materials. For example, a reactor called a rotary kiln generally produces a desired product by heating a hollow kiln section that rotates around a central axis and passing the materials through the kiln section while rolling them. Another reactor called a roller hearth kiln produces a desired product by passing the raw materials and workpieces through a tunnel-shaped kiln section. Various other reactors have also been developed.

[0003] For example, Patent Document 1 discloses the following reaction apparatus. The reaction apparatus has a screw feeder body that serves as a pressure reaction vessel, a catalyst supplying section that introduces a catalyst into the screw feeder body, and a lower hydrocarbon supplying section that introduces lower hydrocarbons into the screw feeder body. The reaction apparatus also has a screw that transports the generated nanocarbon, a solid delivery section that delivers the catalyst and nanocarbon transported by the screw, and a gas delivery section that delivers the generated hydrogen to the outside of the feeder body.

[0004] [Patent Document 1] JP 2006-290682 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, when producing a desired reaction product such as a solid electrolyte, a process of applying heat of, for example, over 1000 degrees Celsius to the raw material is required. Also, when producing a desired reaction product such as a solid electrolyte, it is desirable to contact the raw material with a fluid such as a predetermined atmospheric gas in the reaction process. However, in order to favorably cause a reaction using such a temperature and atmospheric gas, multiple devices including the above-mentioned technology must be used, making it difficult to efficiently produce the desired product.

[0006] The present disclosure has been made to solve such problems, and provides a reaction apparatus and the like that efficiently produces a desired product. [Means for solving the problem]

[0007] The reaction apparatus according to the present disclosure has a kiln section, a fluid supply device, a contact area, and a fluid suction device. The kiln section has a tubular section extending rotatably along a central axis, a raw material supply port for receiving raw materials supplied from one end side of the tubular section, and a discharge port for discharging a reaction product to the other end side of the tubular section. The fluid supply device has a fluid supply pipe extending from one end side or the other end side to the inside of the tubular section, and a fluid supply port provided on the fluid supply pipe so as to be able to discharge a predetermined fluid pressure-fed by the fluid supply pipe to the inside of the tubular section. The contact area is where the fluid discharged from the fluid supply port comes into contact with the raw material. The fluid suction device has a fluid suction port provided so as to be able to suck in the fluid that has passed through the contact area, and a fluid suction pipe for pressure-fed the fluid sucked from the fluid suction port to the outside of the kiln section.

[0008] In the reaction product manufacturing method according to the present disclosure, a user who manufactures a reaction product executes the following steps. The user prepares a kiln section having a tubular section extending rotatably along a central axis, a raw material supply port for receiving raw material supplied from one end side of the tubular section, and a discharge port for discharging the reaction product to the other end side of the tubular section. The user heats the inside of the kiln section to a predetermined temperature. The user releases a predetermined fluid from a fluid supply port provided on the inside of the tubular section at a distance from the tubular section. The user sucks the fluid inside the tubular section from a fluid suction port provided on the inside of the tubular section at a distance from the tubular section. The user supplies raw material from the fluid supply port. The user rotates the kiln section to transport the raw material to the discharge port along a direction parallel to the central axis while contacting the raw material with the fluid, thereby contacting the raw material with the fluid. The user discharges the reaction product from the discharge port. Effect of the Invention

[0011] The present invention will be described below through the embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. In addition, not all of the configurations described in the embodiments are necessarily essential as means for solving the problems. For clarity of explanation, the following description and drawings are omitted and simplified as appropriate. In each drawing, the same elements are given the same reference numerals, and duplicate explanations are omitted as necessary.

[0012] <Embodiment 1> A main configuration of a reaction apparatus according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a cross-sectional side view of a reaction apparatus 10 according to the first embodiment. The reaction apparatus 10 is an apparatus for producing a reaction product by applying conditions such as a predetermined physical stimulus to a raw material.

[0013] The type and state of the raw material and the reaction product are not particularly limited, but may be inorganic such as metal oxides and metal sulfides containing lithium as one of the components, or organic such as hydrocarbons. The shape and size of the raw material and the reaction product are not particularly limited, but the diagonal length when the shape is lumpy is preferably 0.1 mm to 50 mm, more preferably 1 to 20 mm. Furthermore, when the shape of the raw material or the reaction product is lumpy, the ratio of the diagonal length (aspect ratio) is preferably 1 to 10, more preferably 1.3 to 1.8. The reaction device 10 mainly comprises a kiln section 100, a contact area 105, a fluid supply device 120, and a fluid suction device 130. In addition to the above components, the reaction device 10 also comprises a feeder 140, a kiln foot 150, a drive device 160, and the like.

[0014] The kiln section 100 mainly comprises a raw material supply port 101, a discharge port 102, and a tubular section 103. The raw material supply port 101 receives raw material R10 supplied to one end. The discharge port 102 discharges reaction product R11 to the other end. The tubular section 103 is a cylindrical member having the raw material supply port 101 at one end and the discharge port 102 at the other end, and extends rotatably along a central axis C10.

[0015] The kiln section 100 applies a predetermined temperature ranging from room temperature to 1500 degrees Celsius to the raw materials it receives. Therefore, the main components of the kiln section 100 are formed of materials that can withstand this temperature. That is, the kiln section 100 may be formed of, for example, an alloy containing at least one of nickel, cobalt, chromium, iron, copper, aluminum, titanium, tungsten, niobium, tantalum, molybdenum, silicon, boron, and carbon as a component, ceramics containing metal oxides such as alumina and zirconia, nitrides such as silicon nitride, carbides such as titanium carbide, and borides such as chromium boride, carbon such as crystalline graphite and fiber-reinforced graphite, or a composite material, coating material, or bonding material that combines any of the above alloys, the above ceramics, and the above carbon.

[0016] The kiln section 100 may be installed at an incline so that the supply inlet side of the tubular section 103 is higher than the discharge outlet side. In the kiln section 100 shown in Fig. 1, the central axis C10 of the tubular section 103 is inclined at a predetermined angle θ with respect to the horizontal direction. As a result, the kiln section 100 is configured so that the received predetermined raw material R10 is transported to the discharge outlet 102 along the central axis C10 while contacting the inner wall of the tubular section 103. The angle θ may be selected within the range of -90 degrees to +90 degrees.

[0017] A feeder 140 engages with the raw material supply port 101 of the kiln section 100 shown in FIG. 1 via a bearing 104. The feeder 140 rotatably supports the raw material supply port 101 side of the kiln section 100. In other words, the feeder 140 is a support section that supports the kiln section 100. The feeder 140 receives raw material R10 from a raw material inlet 141, which is an opening provided on the top, and guides the received raw material R10 to the raw material supply port 101.

[0018] A kiln foot 150 is engaged with the discharge port 102 of the kiln section 100 via a bearing 104. The kiln foot 150 rotatably supports the side of the discharge port 102. In other words, the kiln foot 150 is a support section that supports the kiln section 100. The kiln foot 150 also has a reaction product outlet 151, and discharges the reaction product R11 discharged from the discharge port 102 from the reaction product outlet 151. Furthermore, the kiln foot 150 fixes the fluid supply device 120 and the fluid suction device 130.

[0019] The feeder 140 may fix at least one of the fluid supply device 120 and the fluid suction device 130 instead of or together with the kiln foot 150. That is, at least one of the feeder 140 and the kiln foot 150 fixes the fluid supply device 120 and the fluid suction device 130 as a support part. In this case, for example, the feeder 140 may fix the fluid supply device 120 and the kiln foot 150 may fix the fluid suction device 130, or vice versa.

[0020] The fluid supplying device 120 is a device for supplying a predetermined fluid to the kiln section 100. The predetermined fluid is a gas or liquid, but may include a solid such as a powder if it has fluidity. The fluid supplying device 120 mainly comprises a fluid supply pipe 121 and a fluid supply port 122. In addition to the above-mentioned components, the fluid supplying device 120 may also have a storage section for storing the predetermined fluid and a pump for pumping the fluid.

[0021] The fluid supply pipe 121 is a pipe for transporting a fluid, configured to extend from one end side or the other end side of the kiln section 100 to the inside of the tubular section 103. In FIG. 1, the fluid supply pipe 121 is fixed to the kiln foot 150 and extends from the kiln foot 150 toward the tubular section 103 of the kiln section 100.

[0022] Fluid supply port 122 is an opening provided in fluid supply pipe 121 so as to be able to release a predetermined fluid pressure-fed by fluid supply pipe 121 to the inside of tube portion 103. Fluid supply port 122 shown in Fig. 1 is provided with a plurality of holes. However, fluid supply port 122 may be a single hole, or may be a porous member that allows the predetermined fluid to pass through.

[0023] The fluid suction device 130 is a device for sucking in the fluid present inside the kiln section 100 and discharging it to the outside of the kiln section 100. The fluid sucked by the fluid suction device 130 includes, for example, a fluid supplied by the fluid supply device 120 and that has come into contact with the raw material R10. The fluid suction device 130 mainly comprises a fluid suction pipe 131 and a fluid suction port 132. In addition to the above-mentioned components, the fluid suction device 130 may also comprise a suction pump for actively sucking in the fluid, a forced exhaust device, and the like.

[0024] The fluid suction port 132 is an opening that is provided so as to be able to suck in the fluid that has passed through the contact area 105. The fluid suction pipe 131 is a pipe that pumps the fluid sucked from the fluid suction port 132 to the outside of the kiln section 100. In FIG. 1, the fluid suction pipe 131 is fixed to the kiln foot 150 and extends from the kiln foot 150 toward the tubular section 103 of the kiln section 100.

[0025] The above-mentioned fluid supply device 120 and fluid suction device 130 may be formed, for example, from an alloy containing at least one of nickel, cobalt, chromium, iron, copper, aluminum, titanium, tungsten, niobium, tantalum, molybdenum, silicon, boron, and carbon as a component; ceramics containing metal oxides such as alumina and zirconia, nitrides such as silicon nitride, carbides such as titanium carbide, and borides such as chromium boride; or carbon such as crystalline graphite and fiber-reinforced graphite; or from a composite material, coating material, or bonding material that combines any of the above alloys, ceramics, and carbon.

[0026] The fluid supply device 120 and the inner wall of the cylindrical portion 103 are maintained apart from each other. Similarly, the fluid suction device 130 and the inner wall of the cylindrical portion 103 are maintained apart from each other. This allows the fluid supply device 120 and the fluid suction device 130 to be configured so as not to interfere with the rotation of the kiln portion 100.

[0027] The fluid supply device 120 and the fluid suction device 130 may be fixed to the kiln foot 150 in a connected state, or may be fixed independently to the kiln foot 150. The fluid supply device 120 and the fluid suction device 130 may be fixed to the kiln foot 150 and further supported by the feeder 140.

[0028] As shown in Fig. 1, the fluid suction port 132 and the fluid supply port 122 are preferably spaced apart from each other along a direction parallel to the central axis C10. In Fig. 1, the fluid supply port 122 is located on the upstream side of the cylindrical portion 103, and discharges the fluid below where the raw material R10 exists. The fluid suction port 132 is located downstream away from the fluid supply port 122 in the direction along the central axis C10, and sucks in the fluid present below. With this configuration, the reaction apparatus 10 can be suitably provided with a contact area 105 between the fluid supply port 122 and the fluid suction port 132, which is an area where the fluid supplied from the fluid supply port 122 comes into contact with the raw material R10.

[0029] The contact area 105 is an area where the fluid discharged from the fluid supply port 122 comes into contact with the raw material R10. In FIG. 1, the area indicated by a thick two-dot chain line is the contact area 105. In the contact area 105, the raw material R10 comes into contact with the fluid supplied from the fluid supply device 120 while rolling and flowing. As a result, the raw material R10 becomes a predetermined reaction product R11, which is transported to the delivery port 102. In addition, the fluid supplied from the fluid supply port 122 passes through the contact area 105 and is then sucked into the fluid suction port 132 located downstream of the contact area 105.

[0030] The temperature control device 110 controls the temperature of the kiln section 100 by heating or cooling the outer periphery of the kiln section 100. The temperature control device 110 performs heating in a range of, for example, room temperature to about 1500 degrees Celsius. The temperature control device 110 has a heating device that surrounds the periphery of the cylindrical kiln section 100. The heating device includes any heater that can control the temperature, such as an induction heater, a sheath heater, a coil heater, or a ceramic heater. Alternatively, the heating device may be one that circulates a fluid heated by burning gas. The temperature control device 110 may include a control device for controlling the temperature of the kiln section 100. For example, the temperature control device 110 may have a thermometer for monitoring the temperature at a predetermined position of the kiln section 100.

[0031] A plurality of temperature control devices 110 may be installed along the extension direction of the kiln section 100. For example, the reaction device 10 may have a first temperature control unit 110A on a side relatively close to the raw material supply port 101 and at a position away from the raw material supply port 101, and a second temperature control unit 110B on a side relatively closer to the discharge port 102 than the first temperature control unit 110A. In this case, for example, the internal temperature at the raw material supply port 101 is room temperature in the region of the raw material supply port 101. Furthermore, the first temperature control unit 110A controls the internal temperature of the kiln section 100 to be, for example, 500 degrees. Furthermore, the second temperature control unit 110B controls the internal temperature of the kiln section 100 to be, for example, 1500 degrees.

[0032] In this case, the reaction apparatus 10 may degrease the raw material R10 in a region of the temperature (500 degrees) set by the first temperature control section 110A, and sinter the raw material R10 in a region of the temperature (1500 degrees) set by the second temperature control section 110B. As described above, the reaction apparatus 10 has a plurality of temperature control sections, so that a plurality of temperature profiles can be set along the extension direction of the kiln section 100. With the above-mentioned configuration, the reaction apparatus 10 rotates the kiln section 100 and heats the kiln section 100. When heat is transmitted to the tube section 103, the heat is radiated into the inside of the kiln section 100.

[0033] The driving device 160 has a motor and a driving force transmission unit 161 that fits onto a driving shaft protruding from the motor. The driving device 160 rotates the kiln unit 100 by driving the driven unit 106 with the driving force transmission unit 161. The driving force transmission unit 161 and the driven unit 106 are, for example, gears that are configured to mesh with each other. With this configuration, the driving device 160 rotates the kiln unit 100 around the central axis C10 as the center of rotation. As a result, the kiln unit 100 transports the raw material R10 received from the raw material supply port 101 to the discharge port 102 while rolling it.

[0034] Next, the process executed by the reaction device 10 will be described with reference to Fig. 2. Fig. 2 is a flowchart of the process (reaction product manufacturing method) executed by the reaction device. The flowchart shown in Fig. 2 is executed by a user who uses the reaction device 10 to manufacture a reaction product, for example.

[0035] First, the user prepares the reaction apparatus 10 including the kiln section 100 (step S11). The reaction apparatus 10 prepared by the user has the above-mentioned configuration.

[0036] Next, the user operates the reaction apparatus 10 and causes the temperature control device 110 to heat the kiln section 100. That is, the temperature control device 110 heats the inside of the kiln section 100 to a predetermined temperature (step S12).

[0037] Next, the user operates the reaction device 10 to cause the fluid supply device 120 to supply a predetermined fluid. The user also operates the reaction device 10 to cause the fluid suction device 130 to suck in the fluid. As a result, the fluid supply device 120 discharges the predetermined fluid from the fluid supply port 122 provided on the inside of the cylindrical portion 103, and the fluid suction device 130 sucks in the fluid inside the cylindrical portion 103 from the fluid suction port 132 provided on the inside of the cylindrical portion 103 (step S13).

[0038] Next, the user supplies the raw material R10 to the kiln section 100 from the raw material supply port 101 (step S14). The user supplies the raw material R10 to the raw material supply port 101 by putting the raw material R10 into the feeder 140.

[0039] Next, the user rotates the kiln section 100 to transport the raw material R10 downstream and contact it with a predetermined fluid in the contact area 105 (step S15). In order to transport the raw material R10 supplied to the kiln section 100 downstream, the user preferably starts the rotation of the kiln section 100 after step S11 and before step S12. At this time, the reaction apparatus 10 rotates the kiln section 100 by driving the drive device 160.

[0040] Next, the user causes the reaction product to be discharged from the outlet 102 (step S16).

[0041] The above describes the reaction product production method executed by the reaction apparatus 10. The above-mentioned method is shown along the flow from when the reaction apparatus 10 produces the reaction product R11 from the raw material R10 to when the reaction product R11 is discharged. However, the reaction apparatus 10 may perform the rotation operation of the kiln section 100 in step S15, for example, before step S12.

[0042] Although the first embodiment has been described above, the configuration of the first embodiment is not limited to the above. The reaction apparatus 10 may be configured such that the flow of the fluid is from the downstream side to the upstream side. The reaction apparatus 10 may have a fluid supply port 122 in the center of the kiln section 100, a first fluid suction port 132 upstream of the fluid supply port 122, and a second fluid suction port 132 downstream of the fluid supply port 122. That is, in this case, the fluid supplied from the fluid supply port 122 to the kiln section 100 may be branched into one directed toward the first fluid suction port 132 and one directed toward the second fluid suction port 132. With the above-mentioned configuration, the reaction apparatus 10, which is a rotary kiln, can continuously and efficiently contact the raw material R10 with the fluid in the contact area 105. Thus, according to the first embodiment, a reaction apparatus or the like that efficiently produces a desired product can be provided.

[0043] <Embodiment 2> Next, a description will be given of embodiment 2. Embodiment 2 has a function of regulating the flow of fluid inside the kiln section 100.

[0044] Fig. 3 is a cross-sectional view in a side direction of the reaction apparatus 20 according to the second embodiment. The reaction apparatus 20 shown in Fig. 3 differs from the reaction apparatus 10 in the configurations of the fluid supply port 122 and the fluid suction port 132. The reaction apparatus 20 also differs from the reaction apparatus 10 in that it has a support member 170, a baffle plate 171 and a baffle plate 172.

[0045] Fluid supply port 122 in the second embodiment is set to form an angle α with central axis C10. As a result, fluid supply port 122 has an opening in a direction facing baffle plate 172. In other words, the fluid discharged from fluid supply port 122 hits baffle plate 172, and the flow is regulated by baffle plate 172. As a result, the fluid is guided to contact region 105 and comes into contact with raw material R10.

[0046] The fluid suction port 132 in the second embodiment is set to form an angle β with the central axis C10. As a result, the fluid suction port 132 has an opening in a direction facing the baffle plate 171. In other words, the fluid that has passed through the contact area 105 is regulated by the baffle plate 171 and is then sucked into the fluid suction port 132.

[0047] The support member 170 is a member extending from the kiln foot 150, which is a support part, to the inside of the tube part 103, and supports the baffle plate 171 and the baffle plate 172. The support member 170 may be configured by combining the fluid supply pipe 121 or the fluid suction pipe 131. The support member 170 may be fixed to the kiln foot 150 and further supported by the feeder 140. The support member 170 may be fixed to the feeder 140, which is a support part, and extend from the feeder 140 to the tube part 103. The support member 170 may be fixed to the feeder 140 and further supported by the kiln foot 150.

[0048] The baffle plate 171 is a plate-like member disposed between the fluid suction port 132 and the delivery port 102. The baffle plate 171 is supported by the support member 170 so as not to impede the rotation of the kiln section 100. The baffle plate 171 regulates the flow of the fluid in a direction parallel to the central axis C10 outside the contact area 105, which is a space formed between the fluid supply port 122 and the fluid suction port 132 in the cylindrical section 103. That is, by disposing the baffle plate 171, the reaction apparatus 20 can suitably guide the fluid that has passed through the contact area 105 to the fluid suction port 132 and suck the fluid.

[0049] The baffle plate 172 is a plate-like member disposed between the raw material supply port 101 and the fluid supply port 122, and is supported by the support member 170 in the same manner as the baffle plate 171. The baffle plate 172 regulates the flow of the fluid in a direction parallel to the central axis C10 outside the contact area 105 in the cylindrical portion 103. That is, by disposing the baffle plate 172, the reaction apparatus 20 can suitably guide the fluid discharged from the fluid supply port 122 to the contact area 105.

[0050] As described above, the baffle plate 171 and the baffle plate 172 are provided on one end side and the other end side, respectively, along a direction parallel to the central axis C10 so as to sandwich the fluid supply port 122 and the fluid suction port 132. This allows the reaction device 20 to suitably form the contact area 105 and to bring the fluid and the raw material R10 into contact with each other in the contact area 105. Furthermore, the reaction device 20 can efficiently suck in the fluid after contacting with the raw material R10.

[0051] The shape of the baffle in this embodiment may have an uneven shape or a curved shape in order to achieve the object of this embodiment. The upper parts of the baffle 171 and the baffle 172 shown in Fig. 3 are bent toward the upstream side. This is for the purpose of forming a suitable flow of the fluid supplied from the fluid supply device 120. The lower parts of the baffle 171 and the baffle 172 are bent toward the downstream side. This is for the purpose of smoothly transporting the raw material R10 to the downstream side. The baffle may have various shapes other than the above-mentioned shapes.

[0052] Next, the configuration of the baffle plate will be further described with reference to Fig. 4. Fig. 4 is a cross-sectional view in the front direction of the reaction apparatus 20 according to the embodiment 2. Fig. 4 is a cross-sectional view of the IV-IV section in Fig. 3, observed from a direction parallel to the central axis C10.

[0053] The reaction apparatus 20 is provided with a temperature control device 110 on the outer periphery of a kiln section 100 configured in an annular shape. The reaction apparatus 20 also includes a support member 170, a baffle plate 171, a fluid supply device 120, and a fluid suction device 130 inside the kiln section 100.

[0054] The support member 170 has a fluid supply device 120 and a fluid suction device 130, which are tubular holes formed inside along the extension direction. In the cross-sectional view shown in Figure 4, the fluid suction device 130 protrudes from the lower part of the support member 170 and forms a fluid suction port 132.

[0055] The baffle plate 171 has a disk shape spaced apart enough not to contact the inner wall of the tubular portion 103. The lower part of the baffle plate 171 is relatively far from the inner wall of the tubular portion 103 in order to ensure a space for the raw material R10 to pass through. This allows the fluid to suitably contact the raw material R10 in the contact region 105, and is further restricted by the baffle plate 171 so as to be sucked through the fluid suction port 132. The raw material R10 also suitsably contacts the fluid in the contact region 105, and is further transported downstream from the space provided below the baffle plate 171.

[0056] The above describes the second embodiment. With the above-mentioned configuration, the reaction device 20 can efficiently produce the reaction product R11. That is, according to the present embodiment, a reaction device or the like that efficiently produces a desired product can be provided.

[0057] <Embodiment 3> Next, a third embodiment will be described. Fig. 5 is a cross-sectional view of a side surface of a reaction apparatus 30 according to the third embodiment. The reaction apparatus 30 differs from the second embodiment in the configurations of a fluid supply device, a fluid suction device, a baffle plate, and a contact area. The reaction apparatus 30 also differs from the second embodiment in the aspect of a temperature control device 110.

[0058] The fluid supply device 120 in this embodiment has a plurality of first fluid supply ports 122A and a second fluid supply port 122B so as to be able to supply a plurality of fluids separately at different positions along a direction parallel to the central axis C10. This allows the reaction device 30 to supply fluids separately at a plurality of different positions.

[0059] Moreover, the reaction apparatus 30 in this embodiment has a baffle plate 173. The baffle plate 173 regulates the flow of the fluid in the direction parallel to the central axis C10 between the first fluid supply port 122A and the second fluid supply port 122B. The baffle plate 173 allows the reaction apparatus 30 to separately control the flow of the fluid discharged from the first fluid supply port 122A and the flow of the fluid discharged from the second fluid supply port 122B.

[0060] Furthermore, the fluid suction device 130 in this embodiment has a first fluid suction port 132A and a second fluid suction port 132B. The first fluid suction port 132A is provided to suck in the fluid discharged from the first fluid supply port 122A. The second fluid suction port 132B is provided to suck in the fluid discharged from the second fluid supply port 122B. That is, the fluid suction device 130 has a plurality of fluid suction ports provided corresponding to the plurality of fluid supply ports, respectively.

[0061] With the above-mentioned configuration, the reaction device 30 is configured with the first contact area 105A and the second contact area 105B. That is, in the first contact area 105A, the fluid supplied from the first fluid supply port 122A comes into contact with the raw material R10, and is then sucked by the first fluid suction port 132A. The first contact area 105A is sandwiched between the baffle plate 172 and the baffle plate 173. This allows the fluid and the raw material R10 to be appropriately contacted in the first contact area 105A.

[0062] In the second contact area 105B, the fluid supplied from the second fluid supply port 122B comes into contact with the raw material R10 and is then sucked in by the second fluid suction port 132B. The second contact area 105B is sandwiched between the baffle plate 173 and the baffle plate 171. This allows the fluid and the raw material R10 to come into contact with each other in an optimal manner in the second contact area 105B.

[0063] In the reaction device 30 in this embodiment, the fluid supply device 120 may be configured so that different types of fluids (for example, the first fluid and the second fluid) flow through the first fluid supply port 122A and the second fluid supply port 122B. That is, in this case, the fluid supply device 120 has a first fluid supply pipe 121A and a first fluid supply port 122A for supplying the first fluid, and a second fluid supply pipe 121B and a second fluid supply port 122B for supplying the second fluid. Also in this case, the raw material R10 and the first fluid come into contact with each other in the first contact area 105A. The raw material R10 and the second fluid come into contact with each other in the second contact area 105B after coming into contact with the first fluid downstream of the first contact area 105A. The fluid suction device 130 sucks the first fluid in the first contact area 105A and sucks the second fluid in the second contact area 105B.

[0064] The fluid suction device 130 may have a first fluid suction pipe 131A corresponding to the first fluid suction port 132A, and may also have a second fluid suction pipe 131B corresponding to the second fluid suction port 132B. With this configuration, the reaction device 30 can separate and suck the fluids in different contact areas.

[0065] With the above-mentioned configuration, the reaction apparatus 30 has a baffle plate 173 between the first contact area 105A and the second contact area 105B for separating the flow of the first fluid from the flow of the second fluid, so that each contact area can be suitably separated and a desired reaction can occur in each area.

[0066] In this case, the temperature control device 110 that controls the temperature of the kiln section 100 may have a first temperature control section 110A that controls the temperature of the first contact area 105A and a second temperature control section 110B that controls the temperature of the second contact area 105B. This allows the temperature control device 110 to perform temperature control separately for multiple contact areas. For example, the temperature control device 110 controls the temperature of the first contact area 105A to 500 degrees by the first temperature control section 110A, and controls the temperature of the second contact area 105B to 1000 degrees by the second temperature control section 110B.

[0067] The third embodiment has been described above. The above-mentioned reaction device 30 has two contact areas 105, but the reaction device 30 may have three or more different contact areas. The temperature control device 110 may have a cooling device that cools the downstream side of the baffle plate 171 in the configuration of FIG. 5, for example. The above-mentioned reaction device 30 has one fluid supply port 122 and one fluid suction port 132 corresponding to each of the contact areas 105. However, the configuration of the contact area 105 and the corresponding fluid supply port 122 and fluid suction port 132 is not limited to this. That is, the number of fluid supply ports 122 corresponding to one contact area 105 in the reaction device 30 may be one or more. The number of fluid suction ports 132 corresponding to one contact area 105 in the reaction device 30 may be one or more.

[0068] With the above-mentioned configuration, the reaction device 30 can set a plurality of regions each having a different environment in one kiln section 100. Therefore, according to the third embodiment, a reaction device or the like that efficiently produces a desired product can be provided.

[0069] <Fourth embodiment> Next, a fourth embodiment will be described. Fig. 6 is a cross-sectional view in a side direction of a reaction apparatus 40 according to the fourth embodiment. The reaction apparatus 40 according to the fourth embodiment differs from the second embodiment in the shape of the baffle plate.

[0070] The support member 170 in this embodiment is fixed to the kiln foot 150 and supported by the feeder 140. With this configuration, the support member 170 can support any baffle plate formed along the extension direction of the kiln section 100.

[0071] The reaction apparatus 40 has a baffle plate 174 and a baffle plate 175. The baffle plate 174 regulates the flow of the fluid in the contact area 105 along a direction parallel to the central axis C10.

[0072] In the reaction device 40, the fluid discharged from the fluid supply port 122 flows from the upstream side to the downstream side. The raw material R10 supplied from the raw material supply port 101 is also transported toward the outlet 102 on the downstream side. The baffle plate 174 regulates the above-mentioned flow in the contact region 105 of the cylindrical portion 103. That is, the baffle plate 174 can be configured so that the cross-sectional area of ​​the flow path through which the fluid passes changes in the contact region 105.

[0073] This may cause the fluid discharged from the fluid supply port 122 to change in flow velocity or flow direction in the contact region 105. Alternatively, the fluid discharged from the fluid supply port 122 may cause a change in flow flux along the flow direction in the contact region 105. In addition, due to this, the raw material R10 in contact with the fluid may change in movement velocity or movement direction.

[0074] The baffle plate 174 may regulate the flow of the fluid along the direction of rotation of the kiln section 100 in addition to the direction parallel to the central axis C10. For example, the baffle plate 174 may regulate the flow of the fluid in a spiral shape. With the above-mentioned configuration, the baffle plate 174 can appropriately regulate the flow of the fluid with respect to the rolling and flowing raw material R10.

[0075] A specific example shown in Fig. 6 will be described. In the contact area 105, the baffle plate 174 is formed so that the distance from the tubular portion 103 gradually increases from the upstream to the downstream. On a relatively upstream side in the contact area 105, the flow flux formed by the lower surface of the baffle plate 174 and the inner wall of the tubular portion 103 has a cross-sectional area D10. In a central portion in the contact area 105, the flow flux formed by the lower surface of the baffle plate 174 and the inner wall of the tubular portion 103 has a cross-sectional area D20 larger than the cross-sectional area D10. Furthermore, at the downstream end portion in the contact area 105, the flow flux formed by the lower surface of the baffle plate 174 and the inner wall of the tubular portion 103 has a cross-sectional area D30 smaller than the cross-sectional area D20.

[0076] With the above-mentioned configuration, in the contact area 105, the flow rate of the fluid decreases from the upstream toward the center, and the residence time of the raw material R10 and the fluid becomes relatively long in the center. This allows the reaction device 40 to relatively long the contact time between the fluid and R10 in the contact area 105. Therefore, according to the fourth embodiment, it is possible to provide a reaction device or the like that promotes the reaction for producing a desired product and efficiently produces the product.

[0077] 6 restricts the fluid below the fluid suction port 132 to a direction parallel to the central axis C10 between the contact area 105 and the delivery port 102. This allows the fluid and the reaction product generated by passing through the contact area 105 to move smoothly to the delivery port 102. At the delivery port 102, the reaction product R11 falls to the reaction product outlet 151 due to its own weight, and the fluid is sucked into the fluid suction port 132.

[0078] 6 is located between the raw material supply port 101 and the fluid supply port 122, and restricts the inflow of outside air from the raw material supply port 101. The baffle plate 175 also forms a gap between the lower part of the baffle plate 175 and the cylindrical portion 103. As a result, the baffle plate 175 does not prevent the inflow of the raw material R10 while suppressing the inflow of outside air. Furthermore, the baffle plate 175 appropriately guides the fluid discharged from the fluid supply port 122 arranged on the upstream side to the contact area 105.

[0079] <Fifth Preferred Embodiment> Next, a fifth embodiment will be described with reference to FIG. 7. FIG. 7 is a configuration diagram of a reaction system according to the fifth embodiment. The reaction system 1 shown in FIG. 7 is a system in which two reaction devices 10, that is, a first reaction device 10A and a second reaction device 10B, are connected in series. FIG. 7 shows a schematic diagram of the first reaction device 10A and the second reaction device 10B connected to each other. In the reaction system 1, a reaction product outlet 151A for the reaction product in the first reaction device 10A is connected to a raw material inlet 141B in the second reaction device 10B.

[0080] The first reactor 10A shown in the figure generates a reaction product A by applying a predetermined physical stimulus A to the raw material R10 received from a raw material inlet 141A. The first reactor 10A outputs the generated reaction product A from a reaction product outlet 151A.

[0081] The second fluid control region 140A receives the reaction product A delivered from the reaction product outlet 151A of the first reactor 10A at the raw material inlet 141B. The second reactor 10B produces a reaction product B from the reaction product A by applying a predetermined physical stimulus B. The second reactor 10B delivers the produced reaction product B from the reaction product outlet 151B.

[0082] The fifth embodiment has been described above. In the above-mentioned reaction system 1, one or both of the first reaction device 10A and the second reaction device 10B may be any one of the reaction device 20, the reaction device 30, or the reaction device 40. The reaction system 1 may also be a system in which three or more reaction devices are connected. With such a configuration, the reaction system 1 according to the fifth embodiment can continuously apply multiple physical stimuli such as stirring, rolling, heating, and cooling to the raw material. With such a configuration, the reaction system 1 enables flexible arrangement and flexible system configuration of the system itself. That is, according to the fifth embodiment, a reaction system that efficiently produces a desired product that requires multiple reactions can be provided.

[0083] <Sixth embodiment> Next, a sixth embodiment will be described with reference to Fig. 8. Fig. 8 is a configuration diagram of a reaction system according to the sixth embodiment. The reaction system 2 shown in Fig. 8 has a granulator 210 and a reaction device 10 as main components.

[0084] The granulation device 210 applies pressure to the powdered raw material to produce granulated material. The granulated material is produced by applying a pressure of, for example, 10 to 700 megapascals to powdered granules consisting of secondary particles of, for example, several tens to several hundreds of microns. The means for applying pressure is not particularly limited, but considering production efficiency, a continuous pressure method using a rotating die roll is preferable. The shape of the granulated material is not particularly limited, but considering ease of transportation in the granulation device 210, it is preferable that the granulated material has a tablet shape such as a sphere, a disk, or an ellipsoid. The size of the granulated material is, as a guideline, a diameter or a long side length of the granulated material of several millimeters to several tens of millimeters, but it is preferable that it is 30 millimeters or less. In addition, considering the efficiency of the reaction in the granulation device 210, it is preferable that the sizes of the granulated materials are about the same as each other. In addition, when applying pressure in the production of granulated material, for example, a small amount of binder resin having a vinyl group or an imide group may be added during granulation in order to improve granulation properties and disintegration properties after the reaction of the granulated material, or raw materials with which an organic polymer binder has been mixed in advance may be used. The granulation device 210 supplies the produced granulated material to the raw material inlet 141.

[0085] The reactor 10 receives the granulated material at the raw material inlet 141 and supplies the received granulated material to the kiln section 100. The reactor 10 applies a predetermined atmosphere and physical stimulation to the received granulated material to generate a reaction product. The reactor 10 generates the reaction product and discharges the generated reaction product from the reaction product outlet 151.

[0086] The sixth embodiment has been described above. In the reaction system 2 according to the present embodiment, pressure is applied to the raw materials in the granulator 210, and then the raw materials are stirred while being heated in the reaction device 10 in which the atmosphere is controlled. This allows the reaction system 2 to continuously produce, for example, an oxide-based solid electrolyte or a sulfide-based solid electrolyte. That is, according to the sixth embodiment, a desired reaction product can be efficiently and continuously produced.

[0087] <Embodiment 7> Next, a seventh embodiment will be described. FIG. 9 is a configuration diagram of a battery material manufacturing system 3 according to the seventh embodiment. The battery material manufacturing system 3 shown in FIG. 9 is a system for manufacturing, for example, a solid electrolyte sheet and a battery laminate of a solid secondary battery. The battery material manufacturing system 3 has a first process area P31, a second process area P32, a third process area P33, and a fourth process area P34 as main components. That is, the battery material manufacturing system 3 manufactures a battery material through the above-mentioned first process, second process, third process, and fourth process.

[0088] The following example is a process for producing a solid electrolyte sheet and a battery laminate using a battery material production system 3. In a first process area P31, the battery material production system 3 produces a solid electrolyte. The first process area P31 mainly includes a granulator 210 and a reactor 10.

[0089] In the first process area P31, the granulator 210 receives raw material in the form of powder and applies pressure to produce tablet-shaped granules. The granulator 210 supplies the produced granules to the reactor 10. The reactor 10 heats and stirs the received granules to produce a solid electrolyte. The reactor 10 supplies the produced solid electrolyte to the second process area P32.

[0090] In the second process area P32, the battery material manufacturing system 3 mixes and kneads the solid electrolyte and the binder resin. The second process area P32 has an extruder 350. The extruder 350 receives the solid electrolyte produced in the first process area P31 together with the binder resin that is supplied separately, and mixes and kneads the received solid electrolyte and binder resin to manufacture a kneaded product. The extruder 350 supplies the manufactured kneaded product to the third process area P33.

[0091] In the third process area P33, the battery material manufacturing system 3 receives the kneaded material from the second process area P32 and produces a solid electrolyte sheet from the received kneaded material. The third process area P33 mainly includes an extruder 360, a coater 370, a dryer 380, and a rolling machine 390.

[0092] The extrusion molding machine 360 ​​receives the kneaded material from the extruder 350, and extrudes the received kneaded material to continuously manufacture a sheet-shaped molded product. At this time, the third process area P33 may combine a base material 361 such as a nonwoven fabric with the sheet extruded by the extrusion molding machine 360 ​​to integrate them. That is, the third process area P33 includes a sheet manufacturing apparatus. The extrusion molding machine 360 ​​may be referred to as a sheet manufacturing apparatus 360.

[0093] Next, coater 370 applies a predetermined positive electrode active material, etc., to the surface of the molded product. Further, dryer 380 dries the molded product on which the predetermined positive electrode active material, etc., has been applied, and supplies it to rolling machine 390. Rolling machine 390 rolls the dried molded product and supplies it to fourth process area P34.

[0094] In the fourth process area P34, the battery material manufacturing system 3 has a process of laminating predetermined sheets and winding them up. The fourth process area P34 mainly comprises a laminator 400 and a winding machine 410. The laminator 400 laminates a negative electrode sheet 401 (or an electrode sheet) containing a negative electrode active material to a sheet-like molded product supplied from the rolling machine 390, and supplies the laminated battery stack to the winding machine 410. The winding machine 410 winds up the battery stack.

[0095] The configuration of the battery material manufacturing system 3 and the battery material manufacturing method executed by the battery material manufacturing system 3 have been described above. The battery material manufacturing system 3 according to this embodiment can consistently and efficiently manufacture reaction products such as solid electrolytes that require multiple reactions, and continuously manufacture sheets using the manufactured reaction products. Note that the battery material manufacturing system 3 according to this embodiment is not limited to the one shown in FIG. 9. For example, the battery material manufacturing system 3 does not need to have the winder 410 in the fourth process area P34.

[0096] The system shown in Fig. 9 can also produce a specific material other than a battery material. That is, the system shown in Fig. 9 can be called a material production system or a solid electrolyte production system. Also, the method executed by such a material production system can be called a material production method.

[0097] 9 can produce a solid electrolyte sheet in the third process area P33 and laminate an electrolyte sheet including a negative electrode sheet in the fourth process area P34, as described above. This allows the battery material production system 3 to produce a battery laminate. That is, in this case, the system shown in FIG. 9 can be called a battery production system, and the method executed by the system shown in FIG. 9 can be called a battery production method.

[0098] As described above, according to the seventh embodiment, it is possible to provide a system or method for efficiently producing a desired battery material, battery, or predetermined material.

[0099] The present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit and scope of the present invention. [Explanation of symbols]
