Note that the fluid supply device 120 and the inner wall of the tubular portion 103 are kept separated from each other. Similarly, the fluid suction device 130 and the inner wall of the cylindrical portion 103 are kept separated from each other. Accordingly, the fluid supply device 120 and the fluid suction device 130 are configured so as not to hinder the rotation of the kiln section 100 .

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 to the kiln foot 150 independently of each other. The fluid supply device 120 and fluid suction device 130 may be fixed to the kiln foot 150 and further supported by the feeder 140 .

As shown in FIG. 1, the fluid suction port 132 and the fluid supply port 122 are preferably separated 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 downward where the raw material R10 exists. Further, the fluid suction port 132 is positioned downstream away from the fluid supply port 122 in the direction along the central axis C10 and sucks the fluid present below. With such a configuration, the reactor 10 preferably provides the contact area 105 between the fluid supply port 122 and the fluid suction port 132, which is the area where the fluid supplied from the fluid supply port 122 and the raw material R10 come into contact. can be done.

The contact area 105 is an area where the fluid discharged from the fluid supply port 122 and the raw material R10 come into contact. A contact area 105 is indicated by a thick two-dot chain line in FIG. In the contact area 105, the raw material R10 contacts 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 and is conveyed to the delivery port 102. Further, the fluid supplied from the fluid supply port 122 is sucked into the fluid suction port 132 located downstream of the contact region 105 after passing through the contact region 105 .

The temperature control device 110 controls the temperature of the kiln section 100 by heating or cooling the outer peripheral portion of 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, for example, a heating device surrounding the cylindrical kiln section 100 .

For example, the temperature control device 110 may have a thermometer at a predetermined location in the kiln section 100 to monitor the temperature.

A plurality of temperature control devices 110 may be installed along the extension direction of the kiln section 100 . For example, the reactor 10 has a first temperature control section 110A at a position relatively close to the raw material supply port 101 and at a position spaced apart from the raw material supply port 101. can have the second temperature control section 110B on the side relatively close to the .

Also, the first temperature control section 110A controls the internal temperature of the kiln section 100 to be, for example, 500 degrees. Furthermore, the second temperature control section 110B controls the internal temperature of the kiln section 100 to be, for example, 1500 degrees.

In this case, the reactor 10 degreases the raw material R10 in the temperature range (500 degrees) set by the first temperature control section 110A, and degreases the raw material R10 in the temperature range (1500 degrees) set by the second temperature control section 110B. Raw material R10 may be sintered. As described above, the reactor 10 can set a plurality of temperature profiles along the extending direction of the kiln section 100 by having a plurality of temperature control sections. The reactor 10 rotates the kiln section 100 and heats the kiln section 100 with the above-described configuration.

The driving device 160 has a motor and a driving force transmission portion 161 fitted to a driving shaft protruding from the motor. The drive unit 160 rotates the kiln unit 100 by driving the driven unit 106 through the driving force transmission unit 161 . The driving force transmission portion 161 and the driven portion 106 are, for example, gears configured to mesh with each other. The driving device 160 rotates the kiln section 100 around the central axis C10 with such a configuration. As a result, the kiln unit 100 conveys the raw material R10 received from the raw material supply port 101 to the delivery port 102 while rolling.

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 suction the fluid. As a result, the fluid supply device 120 discharges a predetermined fluid from the fluid supply port 122 provided inside the tubular portion 103 , and the fluid suction device 130 causes the fluid suction port 132 provided inside the tubular portion 103 to to suck the fluid inside the cylindrical portion 103 (step S13).

Next, the user supplies the raw material R10 from the raw material supply port 101 to the kiln section 100 (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 .

Next, the user rotates the kiln section 100 to convey the raw material R10 downstream and bring it into contact with a predetermined fluid in the contact area 105 (step S15). The user preferably starts rotating the kiln unit 100 after step S11 and before step S12 in order to convey the raw material R10 supplied to the kiln unit 100 downstream. At this time, the reaction apparatus 10 rotates the kiln section 100 by driving the driving device 160 .

Next, the user causes the reaction product to be delivered from delivery port 102 (step S16).

The reaction product manufacturing method executed by the reactor 10 has been described above. The method described above is shown along the flow of reactor 10 producing reaction product R11 from feedstock R10 and delivering the produced reaction product R11. However, the reaction apparatus 10 may perform the rotation operation of the kiln section 100 in step S15 before step S12, for example.

Although the first embodiment has been described above, the configuration of the first embodiment is not limited to the above. The reactor 10 may be configured such that the fluid flows from the downstream side to the upstream side.

That is, in this case, the fluid supplied from the fluid supply port 122 to the kiln section 100 may branch into one directed to the first fluid suction port 132 and one directed to the second fluid suction port 132 . With the above configuration, the reactor 10, which is a rotary kiln, can bring the raw material R10 into continuous and efficient contact with the fluid in the contact area 105. As shown in FIG. Therefore, according to Embodiment 1, it is possible to provide a reaction apparatus or the like for efficiently producing a desired product.

Reactor 20 shown in FIG. 3 differs from reactor 10 in the form of fluid supply port 122 and fluid suction port 132 . Moreover, the reactor 20 differs from the first embodiment in that it has a support member 170 , a baffle plate 171 and a baffle plate 172 .

The fluid supply port 122 in Embodiment 2 is set to form an angle α with the central axis C10. As a result, the fluid supply port 122 has an opening facing the baffle plate 172 . In other words, the fluid discharged from the fluid supply port 122 hits the baffle plate 172 and is restricted in flow by the baffle plate 172 . The fluid is thereby guided to the contact area 105 and contacts the raw material R10.

The fluid suction port 132 in Embodiment 2 is set to form an angle β with the central axis C10. As a result, the fluid suction port 132 has an opening 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 then sucked into the fluid suction port 132 .

The support member 170 is a member extending from the kiln foot 150 as a support portion toward the inner side of the tubular portion 103 and supports the baffle plates 171 and 172 . Note that 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 also be fixed to the feeder 140 and further supported by the kiln foot 150 .

The baffle plate 171 is a plate-like member arranged 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 hinder the rotation of the kiln section 100 . The baffle plate 171 regulates the flow of fluid in the direction parallel to the central axis C10 outside the contact area 105, which is the space formed between the fluid supply port 122 and the fluid suction port 132 in the cylindrical portion 103. That is, by arranging the baffle plate 171 , the reactor 20 can suitably guide the fluid that has passed through the contact area 105 to the fluid suction port 132 and suck this fluid.

The baffle plate 172 is a plate-like member arranged between the raw material supply port 101 and the fluid supply port 122 , and is supported by the support member 170 like the baffle plate 171 . The baffle plate 172 regulates the flow of fluid in the direction parallel to the central axis C10 outside the contact area 105 in the tubular portion 103 . That is, the arrangement of the baffle plate 172 allows the reactor 20 to guide the fluid discharged from the fluid supply port 122 preferably to the contact area 105 .

As described above, the baffle plate 171 and the baffle plate 172 are provided at one end side and the other end side so as to sandwich the fluid supply port 122 and the fluid suction port 132 along the direction parallel to the central axis C10. there is Thereby, the reaction device 20 can suitably form the contact area 105 and bring the fluid and the raw material R10 into contact in the contact area 105 . Furthermore, the reactor 20 can efficiently suck the fluid after contact with the raw material R10.

In addition, the shape of the baffle plate in this embodiment may be uneven or curved in order to achieve the purpose of this embodiment. The baffle plate 171 and the baffle plate 172 shown in FIG. 3 have their upper portions bent toward the upstream side. The purpose of this is to favorably form the flow of fluid supplied from the fluid supply device 120 . Baffle plate 171 and baffle plate 172 are bent downstream at their lower portions. This is for the purpose of smoothly conveying the raw material R10 to the downstream side. The baffle plate can have various shapes other than those described above.

Next, the configuration of the baffle plate will be further described with reference to FIG. FIG. 4 is a front sectional view of the reactor 20 according to the second embodiment. FIG. 4 is a sectional view of the IV-IV section of FIG. 3 observed from a direction parallel to the central axis C10.

The reactor 20 also has a support member 170 , a baffle plate 171 , a fluid supply device 120 and a fluid suction device 130 inside the kiln section 100 .

The support member 170 has a fluid supply device 120 and a fluid suction device 130 which are tubular holes formed therein along the extending direction. 4, the fluid suction device 130 protrudes from the lower portion of the support member 170 to form a fluid suction port 132. As shown in FIG.

The baffle plate 171 has a disc shape spaced apart from the inner wall of the cylindrical portion 103 to such an extent that it does not come into contact with the inner wall. In addition, the baffle plate 171 has a relatively large distance from the inner wall of the cylindrical portion 103 at its lower portion in order to secure a space for the raw material R10 to pass through. As a result, the fluid preferably contacts the raw material R10 in the contact area 105 and is sucked from the fluid suction port 132 by being regulated by the baffle plate 171 . In addition, the raw material R10 preferably comes into contact with the fluid in the contact area 105, and is transported downstream from the space provided below the baffle plate 171.

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 then is sucked by the first fluid suction port 132A. The first contact area 105A is sandwiched between baffle plates 172 and 173 . As a result, the first contact area 105A is preferably brought into contact with the fluid and the raw material R10.

Also, in the second contact area 105B, the fluid supplied from the second fluid supply port 122B contacts the raw material R10 and is then sucked by the second fluid suction port 132B. The second contact area 105B is sandwiched between the baffle plate 173 and the baffle plate 171 . Thereby, the second contact area 105B is preferably brought into contact with the fluid and the raw material R10.

In the reaction apparatus 30 according to the present embodiment, the fluid supply device 120 is configured such that different types of fluids (for example, a first fluid and a second fluid) flow through the first fluid supply port 122A and the second fluid supply port 122B. may be configured. That is, in this case, the fluid supply device 120 includes a first fluid supply pipe 121A and a first fluid supply port 122A that supply the first fluid, and a second fluid supply pipe 121B and a second fluid supply port 122B that supply the second fluid. and have In this case, the raw material R10 and the first fluid come into contact with each other in the first contact area 105A. In the second contact area 105B, the raw material R10 and the second fluid come into contact with the first fluid downstream from the first contact area 105A. The fluid suction device 130 sucks the first fluid at the first contact area 105A and the second fluid at the second contact area 105B.

The fluid suction device 130 may have a first fluid suction pipe 131A corresponding to the first fluid suction port 132A and a second fluid suction pipe 131B corresponding to the second fluid suction port 132B. . Such a configuration allows reactor 30 to separate and aspirate fluids in different contact areas.

With the above configuration, the reactor 30 has the baffle plate 173 between the first contact area 105A and the second contact area 105B for partitioning the flow of the first fluid and the flow of the second fluid. Therefore, each contact area can be suitably separated and a desired reaction can be generated in each area.

Further, in this case, the temperature control device 110 that controls the temperature of the kiln section 100 includes a first temperature control section 110A that controls the temperature of the first contact area 105A and a second temperature control section that controls the temperature of the second contact area 105B. and a portion 110B. Thereby, the temperature control device 110 can perform temperature control separately for a plurality of 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 the temperature of the second contact area 105B to 1000 degrees by the second temperature control section 110B. to control.

The third embodiment has been described above. Although the reactor 30 described above has two contact areas 105, the reactor 30 may have three or more different contact areas. Further, the temperature control device 110 may have a cooling device for cooling the downstream side of the baffle plate 171 in the configuration of FIG. 5, for example. Also, one fluid supply port 122 and one fluid suction port 132 corresponding to each of the contact areas 105 of the reaction device 30 are arranged. 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 reactor 30 may be one, or may be one or more. Further, the number of fluid suction ports 132 corresponding to one contact area 105 in the reaction device 30 may be one, or may be one or more.

With the above configuration, the reactor 30 can set a plurality of regions with different environments in one kiln section 100 . Therefore, according to Embodiment 3, it is possible to provide a reaction apparatus or the like for efficiently producing a desired product.

<Embodiment 4>
Next, Embodiment 4 will be described. FIG. 6 is a side cross-sectional view of the reactor 40 according to the fourth embodiment. A reactor 40 according to the fourth embodiment differs from that of the second embodiment in the form of baffle plates.

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

Reactor 40 has baffle 174 and baffle 175 . The baffle plate 174 regulates the flow of fluid in the contact area 105 along the direction parallel to the central axis C10.

In the reactor 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 conveyed toward the delivery port 102 on the downstream side. The baffle plate 174 restricts the above-described flow at the contact area 105 of the tubular portion 103 . That is, the baffle 174 may be configured such that the cross-sectional area of the flow path through which the fluid passes in the contact area 105 varies.

As a result, the fluid discharged from the fluid supply port 122 can change its flow velocity and flow direction in the contact area 105 . Alternatively, the fluid discharged from the fluid supply port 122 may change in flux along the direction of flow at the contact area 105 . In addition, along with this, the moving speed and moving direction of the raw material R10 in contact with the fluid may change.

The baffle plate 174 may restrict the flow of fluid along the rotation direction of the kiln section 100 in addition to the direction parallel to the central axis C10. For example, the baffle plate 174 may spirally regulate the flow of fluid. With the above configuration, the baffle plate 174 can suitably regulate the flow of the fluid with respect to the raw material R10 that rolls and flows.

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 upstream to downstream. Relatively upstream in the contact area 105, the flux formed by the lower surface of the baffle plate 174 and the inner wall of the cylindrical portion 103 has a cross-sectional area D10. At the central portion of the contact area 105, the 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 of the contact area 105, the flux formed by the lower surface of the baffle plate 174 and the inner wall of the cylindrical portion 103 has a cross-sectional area D30 smaller than the cross-sectional area D20.

With the above configuration, in the contact area 105, the flow velocity of the fluid decreases from the upstream toward the central portion, and the retention time of the raw material R10 and the fluid becomes relatively long in the central portion. This allows the reactor 40 to have a relatively long contact time between the fluid and R10 in the contact area 105 . Therefore, according to Embodiment 4, it is possible to provide a reactor or the like that promotes the reaction for manufacturing a desired product and efficiently manufactures the desired product.

The baffle plate 174 shown in FIG. 6 regulates the fluid below the fluid suction port 132 between the contact area 105 and the delivery port 102 in a direction parallel to the central axis C10. Thereby, the fluid and the reaction product generated through the contact area 105 smoothly move to the delivery port 102 . At the delivery port 102, the reaction product R11 drops by its own weight to the reaction product outlet 151, and the fluid is sucked into the fluid suction port 132.

A baffle plate 175 shown in FIG. 6 is positioned between the raw material supply port 101 and the fluid supply port 122 and regulates the inflow of outside air from the raw material supply port 101 . Also, the baffle plate 175 forms a gap with the cylindrical portion 103 at its lower portion. As a result, the baffle plate 175 prevents the inflow of the raw material R10 while suppressing the inflow of outside air. Furthermore, the baffle plate 175 preferably guides the fluid discharged from the fluid supply port 122 arranged downstream to the contact area 105 .

<Embodiment 5>
Next, Embodiment 5 will be described with reference to FIG. FIG. 7 is a configuration diagram of a reaction system according to a fifth embodiment. The reaction system 1 shown in FIG. 7 is a system in which two reactors 10, that is, a first reactor 10A and a second reactor 10B are connected in series. FIG. 7 schematically shows a state in which the first reactor 10A and the second reactor 10B are connected. In the reaction system 1, the reaction product outlet 151A for the reaction product in the first reactor 10A and the raw material inlet 141B in the second reactor 10B are connected.

The first reactor 10A shown in the figure produces a reaction product A by applying a predetermined physical stimulus A to a raw material R10 received from a raw material inlet 141A. The first reactor 10A sends out the produced reaction product A from the reaction product outlet 151A.

The second fluid control area 140A receives the reaction product A delivered from the reaction product outlet 151A of the first reactor 10A into the raw material inlet 141B. The second reactor 10B generates a reaction product B from the reaction product A by applying a predetermined physical stimulus B. The second reactor 10B sends out the produced reaction product B from the reaction product outlet 151B.

The fifth embodiment has been described above. In the reaction system 1 described above, one or both of the first reactor 10A and the second reactor 10B may of course be either the reactor 20, the reactor 30 or the reactor 40. Moreover, the reaction system 1 may be one 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 a plurality of physical stimuli such as stirring, rolling, heating, and cooling to the raw material. Moreover, with such a configuration, the reaction system 1 enables flexible arrangement of the system itself and flexible system configuration. That is, according to Embodiment 5, it is possible to provide a reaction system for efficiently producing a desired product requiring multiple reactions.

The granulator 210 produces granules by applying pressure to raw materials, which are granules. The granules are produced by applying a pressure of, for example, 10 to 700 megapascals to a granular material composed of secondary particles of about several tens to several hundreds of microns. The means for applying pressure is not particularly limited, but in consideration of production efficiency, a continuous pressurization method using rotating die rolls is desirable. The shape of the granules is not particularly limited, but considering ease of transportation in the granulation device 210, it is desirable that the granules have a tablet shape such as a spherical shape, a disk shape, or an ellipsoidal shape. As for the size of the granules, the diameter or the length of the long side of the granules is from several millimeters to several tens of millimeters as a guideline, but is preferably 30 millimeters or less. Also, considering the reaction efficiency in the granulator 210, it is desirable that the sizes of the granules are about the same. In addition, when pressurizing in the production of granules, a small amount of binder resin having, for example, a vinyl group or an imide group is added for the purpose of improving granulation properties and improving crushability after reacting the granules. The granulation may be performed while granulating, or a raw material premixed with an organic polymer binder may be used. The granulator 210 supplies the manufactured granules to the raw material inlet 141 .

When the granules are received at the raw material inlet 141 , the reactor 10 supplies the received granules to the kiln section 100 . The reactor 10 applies a predetermined atmosphere and physical stimulation to the received granules to produce reaction products. When the reaction product is produced, the reaction device 10 delivers the produced reaction product from the reaction product outlet 151 .

The sixth embodiment has been described above. In the reaction system 2 according to the present embodiment, the raw material is pressurized in the granulator 210, and then stirred while being heated in the reactor 10 in which the atmosphere is controlled. Thereby, the reaction system 2 can continuously produce, for example, an oxide-based solid electrolyte or a sulfide-based solid electrolyte.
