[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 reactor 10 mainly comprises a kiln section 100, a temperature control device 110, a first reaction auxiliary device 120, and a second reaction auxiliary device 130. In addition to the above components, the reactor 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, the first reaction auxiliary device 120, and the second reaction auxiliary device 130 are made of materials that can withstand this temperature. That is, the components of the kiln section 100, the first reaction auxiliary device 120, and the second reaction auxiliary device 130 are, for example, ceramics such as oxides such as alumina and zirconia, carbides such as silicon carbide and titanium carbide, nitrides such as silicon nitride and titanium nitride, or carbon such as crystalline graphite and fiber-reinforced graphite. Alternatively, the components of the kiln section 100, the first reaction auxiliary device 120, and the second reaction auxiliary device 130 may be heat-resistant alloys containing at least one of alloy elements such as nickel, cobalt, chromium, molybdenum, tungsten, tantalum, titanium, iron, copper, aluminum, silicon, boron, and 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] In the following description, the side relatively closer to the raw material supply port 101 of the kiln section 100 may be referred to as the upstream side, and the side relatively closer to the discharge port 102 may be referred to as the downstream side. In other words, the kiln section 100 is configured so that the received predetermined raw material R10 is transported from the upstream side to the downstream side.
[0018] A feeder 140 is engaged 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. Furthermore, the feeder 140 supports the first reaction auxiliary device 120.
[0019] 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 supports the second reaction auxiliary device 130.
[0020] The temperature control device 110 includes a heating device or a cooling device, and controls the temperature of the kiln section 100 by heating or cooling the kiln section 100. The temperature control device 110 performs heating in a range from room temperature to about 1500 degrees Celsius, for example. The temperature control device 110 has a heating device that surrounds the periphery of the cylindrical section 103 in the intermediate region between the raw material supply port 101 and the discharge port 102, for example. The heating device includes any heater that can control the temperature, such as 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.
[0021] The first reaction auxiliary device 120 and the second reaction auxiliary device 130 are examples of embodiments of the reaction auxiliary device. The reaction auxiliary device has a support extending from one end side or the other end side of the kiln section 100 to the inside of the tubular section 103. The support also has an auxiliary device for assisting the reaction of the raw materials in the middle region of the kiln section 100. The auxiliary device includes at least one of an agitator, a mixer, a pulverizer, a kneader, a conveyor, a fluid injection port, a fluid suction port, and a scraper.
[0022] The first reaction auxiliary device 120 mainly comprises a first support 121 and a stopper 122. The first support 121 is a beam-shaped structure supported by the feeder 140 and protruding from the feeder 140 to the tube part 103. The first support 121 holds the stopper 122 in the middle region of the tube part 103.
[0023] The first reaction auxiliary device 120 will be further described with reference to Fig. 2. Fig. 2 is a first cross-sectional view of the reaction device according to the first embodiment taken along the line II-II of Fig. 1, observed from a direction parallel to the central axis C10.
[0024] The stopper 122 is a disk-shaped member having a main surface parallel to a plane perpendicular to the central axis C10. The outer periphery of the stopper 122 has a gap between the inner wall of the cylindrical portion 103 and the outer periphery, allowing the raw material R10 to pass through. The stopper 122 also has the function of receiving the balls 123 on the side of the raw material supply port 101. A plurality of balls 123 are arranged upstream of the stopper 122 in the kiln portion 100, and move freely as the cylindrical portion 103 rotates. The balls 123 also have a diameter that is such that they cannot pass through the stopper 122.
[0025] As a result, the first reaction auxiliary device 120 and the multiple balls 123 have the function of a ball mill that pulverizes the raw material R10 inside the kiln section 100. In other words, the first reaction auxiliary device 120 is one embodiment of a reaction auxiliary device having a pulverizer as an auxiliary device. By having the first reaction auxiliary device 120, the reaction device 10 can pulverize the raw material R10 and efficiently promote a desired reaction.
[0026] Returning to FIG. 1, the explanation will be continued. The second reaction auxiliary device 130 has a second support 131 and a scraper 132. The second support 131 is a beam-shaped structure supported by the kiln foot 150 and protruding from the kiln foot 150 to the tubular section 103. The second support 131 has a scraper 132, which is an auxiliary device, downstream of the intermediate region of the tubular section 103. The scraper 132 is provided to scrape off the reaction product R11 generated in the intermediate region of the kiln section 100 when it adheres to the inner wall of the tubular section 103.
[0027] The second reaction auxiliary device 130 will be further described with reference to Fig. 3. Fig. 3 is a second cross-sectional view of the reaction device according to the first embodiment taken along the line III-III in Fig. 1, observed from a direction parallel to the central axis C10.
[0028] The scraper 132 is a flat member extending from the second support 131 toward the inner wall of the tube portion 103. The scraper 132 plays a role in scraping off (scraping) the reaction product R11 adhering to the inner wall surface of the tube portion 103. For this reason, the gap between the tip of the scraper 132 and the inner wall of the tube portion 103 is set to a distance sufficient to scrape off the substances adhering to the inner wall. As a result, the reaction product R11 adhering to the inner wall of the tube portion 103 is peeled off from the inner wall and transported to the delivery port 102.
[0029] By including the second reaction auxiliary device 130, the reaction apparatus 10 can prevent the reaction product R11 from adhering to the inner wall of the cylindrical portion 103. This allows the reaction apparatus 10 to efficiently produce the desired reaction product.
[0030] Returning to FIG. 1, the explanation will be continued. 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 transmitting the driving force of the motor to the driven unit 106 via the driving force transmission unit 161. The driving force transmission unit 161 and the driven unit 106 are, for example, gears 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.
[0031] Next, the process executed by the reaction device 10 will be described with reference to Fig. 4. Fig. 4 is a flowchart of the process (reaction product manufacturing method) executed by the reaction device. The flowchart shown in Fig. 4 is executed by using the reaction device 10, for example, by a user who uses the reaction device 10 to manufacture a reaction product.
[0032] 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.
[0033] 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).
[0034] Next, the user supplies the raw material R10 to the kiln section 100 from the raw material supply port 101 (step S13). The user supplies the raw material R10 to the raw material supply port 101 by putting the raw material R10 into the feeder 140.
[0035] Next, the user rotates the kiln section 100 to transport the raw material R10 downstream (step S14). 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 device 10 rotates the kiln section 100 by driving the drive device 160.
[0036] Next, the user causes the first reaction assistant device 120 and the second reaction assistant device 130 to perform a reaction assistant operation (step S15). That is, the user causes the first reaction assistant device 120 to crush the raw material R10. Furthermore, the user causes the second reaction assistant device 130 to scrape the reaction product R11 generated from the raw material R10.
[0037] Next, the user causes the reaction product to be discharged from the outlet 102 (step S16).
[0038] The reaction product manufacturing method executed by the reactor 10 has been described above. According to the above-mentioned method, the reactor 10 receives the raw material R10 in the kiln section 100, promotes a predetermined reaction in the received raw material R10 in the kiln section 100, and generates the reaction product R11. More specifically, the reactor 10 transports the received raw material R10 and crushes it using the first reaction auxiliary device 120. Furthermore, the reactor 10 exposes the crushed raw material R10 to a predetermined temperature environment while rolling and flowing it downstream in the kiln section 100 to generate the reaction product R11. Furthermore, the reactor 10 scrapes the reaction product R11 in the tube section 103 using the second reaction auxiliary device 130 just before the delivery port 102. The reactor 10 then delivers the reaction product R11 from the delivery port 102 and further discharges it from the reaction product outlet 151.
[0039] The above-mentioned method is shown along the flow from the reaction apparatus 10 producing the reaction product R11 from the raw material R10 to the delivery of the produced reaction product R11. However, the method executed by the reaction apparatus 10 is not limited to the above-mentioned order. For example, the reaction apparatus 10 may perform the rotation operation of the kiln section 100 before step S12, or may perform the rotation operation simultaneously with step S12.
[0040] Although the first embodiment has been described above, the reactor 10 according to the first embodiment is not limited to the above-mentioned configuration. The first reaction auxiliary device 120 and the second reaction auxiliary device 130 may have other auxiliary devices. The reactor 10 may have only one of the first reaction auxiliary device 120 and the second reaction auxiliary device 130. The first reaction auxiliary device 120 and the second reaction auxiliary device 130 may each have a plurality of auxiliary devices on their supports.
[0041] The first reaction auxiliary device 120 and the second reaction auxiliary device 130 may each have a plurality of supports. The first support 121 or the second support 131 may have a branched shape inside the tube portion 103. The first support 121 of the first reaction auxiliary device 120 and the second support 131 of the second reaction auxiliary device 130 may be connected to be integrated. That is, the reaction auxiliary device may have supports supported on the raw material supply port 101 side and the delivery port 102 side. A screw may be typically selected as the above-mentioned conveyor, but it is not limited to a screw as long as it has a conveying function. For example, the conveyor may be a pendulum paddle or a rotary paddle, or a belt with paddles that move along the central axis C10. Furthermore, the conveyor is not limited to one that conveys the raw material in contact with it, and may be one that conveys it without contact using a fluid, such as a fan or a jet nozzle.
[0042] In the first embodiment, as described above, the reaction auxiliary device is included, and the reaction apparatus 10, which is a rotary kiln, can continuously and efficiently induce a predetermined reaction in the raw material R10 by utilizing the space of the tubular portion 103 in the kiln portion 100, thereby producing the reaction product R11. Therefore, 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 second embodiment will be described. Fig. 5 is a cross-sectional view of a side surface of a reaction apparatus 20 according to the second embodiment. The reaction apparatus 20 according to the second embodiment differs from the first embodiment in the aspect of a reaction auxiliary device. Also, the reaction apparatus 20 differs from the first embodiment in the aspect of a temperature control device 110.
[0044] The temperature control device 110 controls the temperature inside the cylindrical portion by contacting the outer wall of the cylindrical portion. The temperature control device 110 in this embodiment has a plurality of temperature control parts along the extension direction of the kiln section 100. That is, the temperature control device 110 in this embodiment has a plurality of different temperature control regions in the middle region in the direction along the central axis C10.
[0045] More specifically, the temperature control device 110 includes a first temperature control section 110A, a second temperature control section 110B, and a third temperature control section 110C. The first temperature control section 110A is disposed relatively close to the raw material supply port 101 and at a position spaced apart from the raw material supply port 101. The second temperature control section 110B is disposed downstream of the first temperature control section 110A and upstream of the third temperature control section 110C. The third temperature control section 110C is disposed downstream of the second temperature control section 110B.
[0046] The first temperature control section 110A, the second temperature control section 110B, and the third temperature control section 110C are each set to a different temperature. For example, the first temperature control section 110A controls the internal temperature of the kiln section 100 to, for example, 500 degrees. Furthermore, the second temperature control section 110B controls the internal temperature of the kiln section 100 to, for example, 1500 degrees. The third temperature control section 110C controls the internal temperature of the kiln section 100 to, for example, 40 degrees. In this way, the temperature control device 110 can set different temperatures for different areas of the kiln section 100. This allows the reaction device 20 to promote or suppress a desired reaction depending on the area of the kiln section 100.
[0047] The reaction apparatus 20 in this embodiment has, as a reaction auxiliary device, a reaction auxiliary device 170. The reaction auxiliary device 170 has, as its main components, a support 171, a stirrer 172, a pulverizer 173, a spray 174, a conveyor 175, a reducer 176, a driving force transmission unit 177, and a support drive device 178.
[0048] The reaction auxiliary device 170 has a support 171 rotatably supported at one end and the other end. More specifically, the support 171 is a shaft extending along the central axis C10 of the kiln section 100, and is supported at one end by a bearing 180 provided in the feeder 140 and at the other end by a bearing 180 provided in the kiln foot 150.
[0049] In addition, the support 171 is connected to a support driving device 178 via a reducer 176 and a driving force transmission unit 177. That is, the reaction apparatus 20 in this embodiment further includes a support driving device 178 that rotates the support 171 of the reaction auxiliary device 170.
[0050] The support driving device 178 is a motor, which rotates the driving force transmission unit 177 to transmit the driving force to the reducer 176. The reducer 176 converts the force received from the driving force transmission unit 177, for example, by a combination of multiple gears, into a predetermined number of rotations and transmits it to the support 171.
[0051] The reducer 176, the driving force transmission unit 177, and the support driving unit 178 are mechanisms for rotating the reaction auxiliary device 170. The reaction auxiliary device 170 is supported so that the support 171 can rotate separately from the kiln unit 100. That is, the rotation direction and rotation speed of the kiln unit 100 and the rotation direction and rotation speed of the support 171 may be the same or different. Specifically, for example, the kiln unit 100 rotates at about 0.1 to 10 revolutions per minute, and the reaction auxiliary device 170 rotates at about 0 to 500 revolutions per minute. The rotation speed or direction of the reaction auxiliary device 170 may change with time.
[0052] The reaction auxiliary device 170 has a plurality of auxiliary devices arranged along the extending direction of the support 171. More specifically, the reaction auxiliary device 170 has, in this order from the upstream side, a stirrer 172, a pulverizer 173, a sprayer 174, and a conveyor 175.
[0053] The agitator 172 has a function of agitating the raw material R10 received from the raw material supply port 101. More specifically, the agitator 172 is, for example, a rod-shaped member protruding from the support 171. This rod-shaped member protrudes from the support 171 in a direction perpendicular to the central axis C10, bends at a right angle near the inner wall of the cylindrical portion 103, extends in a direction parallel to the central axis C10, and then bends at a right angle again to connect to the support 171. In the example shown in FIG. 5, the agitator 172 has two of these rod-shaped members. Since the agitator 172 is fixed to the support 171, the raw material R10 is agitated by the rotation of the support 171.
[0054] The pulverizer 173 has a function of pulverizing the raw material R10 stirred by the stirrer 172. The pulverizer 173 has a plurality of plate-like elliptical members having an elliptical main surface. The major axis of each of the elliptical members extends near the inner wall of the tube portion 103. Since the pulverizer 173 is fixed to the support 171, the lump raw material R10 is sandwiched between the pulverizer 173 and the tube portion 103 by the rotation of the support 171, and is pulverized.
[0055] The spray 174 discharges a predetermined fluid into the inside of the tube portion 103 to bring the fluid into contact with the raw material R10. The support 171 has a fluid receiving port 174A at the upstream end and a pipe for sending the granules received from the fluid receiving port 174A to the spray 174. The spray 174 discharges the fluid supplied through the fluid receiving port 174A from a fluid ejection port 174B. That is, the raw material R10 pulverized by the pulverizer 173 comes into contact with the fluid discharged from the spray 174. The fluid discharged from the spray 174 may be an inert gas or a predetermined gas for promoting a reaction. The fluid discharged from the spray 174 may also include a powder or liquid having flowability.
[0056] The conveyor 175 has a function of conveying downstream a predetermined reaction product generated by passing through the area where the spray 174 is arranged. More specifically, the conveyor 175 is a screw that conveys the reaction product by rotating the support 171. The conveyor 175 conveys the reaction product at a conveying speed corresponding to, for example, the pitch of the screw or the rotation speed of the support 171.
[0057] Next, the relationship between the temperature control device 110 and the reaction auxiliary device 170 will be described. In the temperature control device 110, the region where the first temperature control unit 110A controls the temperature is provided with a stirrer 172 and a grinder 173. In the region where the second temperature control unit 110B controls the temperature is provided with a spray 174. And in the region where the third temperature control unit 110C controls the temperature is provided with a transporter 175.
[0058] That is, the reaction device 20 degreases, stirs, and pulverizes the raw material R10 in an area where the first temperature control unit 110A controls the temperature of the kiln unit 100 to about 500 degrees Celsius. Next, the reaction device 20 ejects a predetermined fluid from the fluid injection port 174B in an area where the second temperature control unit 110B controls the temperature to about 1000 degrees Celsius to promote the reaction of the raw material R10. Next, the reaction device 20 transports the reaction product to the delivery port 102 in an area where the third temperature control unit 110C controls the temperature to about 40 degrees Celsius.
[0059] As described above, the reaction apparatus 20 can realize a desired process by linking the temperature control device 110 and the reaction auxiliary device 170. The mode of the auxiliary device of the reaction auxiliary device 170 is not limited to the above example. For example, the configuration of the agitator 172 is not limited to the above configuration as long as it has a function of agitating the raw material R10. The agitator 172 may be a plate-shaped member or a pin-shaped member. In this case, the plate-shaped member is not limited to a flat plate, and may have irregularities or holes. Similarly, the shape of the pulverizer 173 may be, for example, one in which the outer edge has irregularities along the circumferential direction. The pulverizer 173 may be a ball mill using the balls 123 shown in the first embodiment as the pulverizing medium, a bead mill using beads with a diameter smaller than that of the balls 123 as the pulverizing medium, or a rod mill using a rod-shaped object with long and short sides as the pulverizing medium. The reaction auxiliary device 170 may have one or more of the above-mentioned auxiliary devices.
[0060] In addition to the above-mentioned configuration, the reaction auxiliary device 170 may have, for example, an intake port for sucking in gas and discharging it to the outside. The reaction auxiliary device 170 may have a kneader in addition to or instead of the above-mentioned configuration. The configuration and arrangement of the reaction auxiliary device 170 shown in Fig. 5 are only examples, and various combinations of configurations of the auxiliary devices are possible.
[0061] The reaction apparatus 20 may have a plurality of reaction auxiliary devices 170. In this case, for example, the reaction apparatus 20 may have a plurality of supports 171 supported so as to be capable of planetary rotation along an axis parallel to the central axis C10.
[0062] The above describes the reaction apparatus 20. The reaction apparatus 20 can continuously execute a plurality of predetermined steps by including an auxiliary device inside the kiln section 100. Therefore, according to this embodiment, a reaction apparatus or the like that efficiently produces a desired product can be provided.
[0063] <Embodiment 3> Next, the third embodiment will be described with reference to FIG. 6. FIG. 6 is a configuration diagram of a reaction system according to the third embodiment. The reaction system 1 shown in FIG. 6 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. 6 shows a schematic state in which the first reaction device 10A and the second reaction device 10B are connected. The reaction system 1 in this embodiment is an example of realizing a production process of a reaction product that requires a number of steps that exceeds the number of processes that can be performed by one reaction device. 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.
[0064] The first reactor 10A shown in the figure generates a reaction product A by subjecting a raw material R10 received from a raw material inlet 141A to a predetermined reaction. The first reactor 10A outputs the generated reaction product A from a reaction product outlet 151A.
[0065] The second reactor 10B receives the reaction product A discharged from the reaction product outlet 151A of the first reactor 10A at the raw material inlet 141B. The second reactor 10B generates a reaction product B from the reaction product A by providing a predetermined reaction. The second reactor 10B outputs the generated reaction product B from the reaction product outlet 151B.
[0066] The third 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 either the reaction device 10 or the reaction device 20. 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 third embodiment can continuously apply multiple physical stimuli 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, even if the reaction system 1 requires a process that exceeds the number of processes that can be performed by one reaction device, the configuration can be prevented from becoming complicated. As described above, according to the third embodiment, a reaction system that efficiently produces a desired product that requires multiple reactions can be provided.
[0067] <Fourth embodiment> Next, a fourth embodiment will be described with reference to Fig. 7. Fig. 7 is a configuration diagram of a reaction system according to the fourth embodiment. The reaction system 2 shown in Fig. 7 has, as main components, a granulator 210 and a reaction device 20. The reaction device 20 in this embodiment has, at least, an agitator in the middle region as a reaction auxiliary device.
[0068] 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.
[0069] When the reactor 20 receives the granulated material at the raw material inlet 141, it supplies the received granulated material to the kiln section 100. The reactor 20 applies a predetermined physical stimulus and a predetermined atmosphere to the received granulated material to generate a reaction product. More specifically, the reactor 20 agitates the granulated material using the reaction auxiliary device 170, ejects a gas for reaction and sucks in the gas after reaction, and applies a predetermined amount of heat using the temperature control device 110. When the reactor 20 generates a reaction product, it sends out the generated reaction product from the reaction product outlet 151.
[0070] The fourth 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 atmosphere-controlled reactor 20. 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 fourth embodiment, a desired reaction product can be efficiently and continuously produced.
[0071] <Fifth Preferred Embodiment> Next, a fifth embodiment will be described. FIG. 8 is a configuration diagram of a battery material manufacturing system 3 according to the fifth embodiment. The battery material manufacturing system 3 shown in FIG. 8 is an embodiment of a reaction system, and is a system for manufacturing, for example, a solid electrolyte sheet and a battery laminate of a solid secondary battery containing a reaction product. 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 by going through the above-mentioned first process, second process, third process, and fourth process.
[0072] 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 20.
[0073] 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 20. The reactor 20 heats and stirs the received granules to produce a solid electrolyte. The reactor 20 supplies the produced solid electrolyte to the second process area P32.
[0074] 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.
[0075] 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.
[0076] The extrusion molding machine 360 receives the kneaded material from the extruder 350, and extrudes the received kneaded material to continuously produce a sheet-shaped product. At this time, in the third process area P33, a base material 361 such as a nonwoven fabric may be combined with the sheet extruded by the extrusion molding machine 360 to form an integrated body. 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.
[0077] 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.
[0078] 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.
[0079] 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. 8. For example, the battery material manufacturing system 3 does not need to have the winder 410 in the fourth process area P34.
[0080] The reaction system shown in Fig. 8 can also produce a specific material other than a battery material. That is, the reaction system shown in Fig. 8 can be called a material production system or a solid electrolyte production system. Moreover, the method executed by such a material production system can be called a material production method.
[0081] 8 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. In this way, the battery material production system 3 can produce a battery laminate. That is, in this case, the system shown in FIG. 8 can be called a battery production system, and the method executed by the system shown in FIG. 8 can be called a battery production method.
[0082] As described above, according to the fifth embodiment, a reaction system or method for efficiently producing a desired battery material, battery, or predetermined material containing a reaction product can be provided.
