<Embodiment 1>
The main configuration of the reactor according to Embodiment 1 will be described with reference to FIG. FIG. 1 is a side cross-sectional view of a reactor 10 according to Embodiment 1. FIG. The reaction apparatus 10 is an apparatus for producing a reaction product by applying conditions such as predetermined physical stimulation to raw materials.

The shape and size of the raw material and the reaction product are not particularly limited, but when the shape is massive, the diagonal length is preferably 0.1 mm to 50 mm, more preferably 1 to 20 mm. Furthermore, when the shape of the starting material or the reaction product is massive, the diagonal length ratio (aspect ratio) is preferably 1 to 10, more preferably 1.3 to 1.8. The reactor 10 has a kiln section 100, a temperature control device 110, a first auxiliary reaction device 120 and a second auxiliary reaction device 130 as main components. The reactor 10 also has a feeder 140, a kiln foot 150, a driving device 160, etc. in addition to the above configuration.

The kiln section 100 has a raw material supply port 101, a delivery port 102 and a cylindrical portion 103 as its main components. The raw material supply port 101 receives the raw material R10 supplied to one end side. The delivery port 102 delivers the reaction product R11 to the other end. The tubular portion 103 is a cylindrical member having the raw material supply port 101 at one end and the delivery port 102 at the other end, and extends rotatably along the central axis C10.

The kiln section 100 imparts a predetermined temperature in the range of room temperature to 1500 degrees Celsius to the incoming raw material. Therefore, the main constituent members of the kiln section 100, the first auxiliary reaction device 120 and the second auxiliary reaction device 130 are made of members that can withstand this temperature. That is, the members constituting the kiln section 100, the first reaction auxiliary device 120, and the second reaction auxiliary device 130 are, for example, oxides such as alumina and zirconia, carbides such as silicon carbide and titanium carbide, and silicon nitride and titanium nitride. Ceramics, such as nitrides, or carbons, such as crystalline graphite or fiber-reinforced graphite. Alternatively, the members constituting the kiln section 100, the first reaction auxiliary device 120 and the second reaction auxiliary device 130 are nickel, cobalt, chromium, molybdenum, tungsten, tantalum, titanium, iron, copper, aluminum, silicon, boron, carbon, etc. A heat-resistant alloy containing as a component at least one of the alloying elements can be employed.

The kiln part 100 may be installed with an inclination so that the supply port side of the cylindrical part 103 is higher than the delivery port side. In the kiln portion 100 shown in FIG. 1, the central axis C10 of the cylindrical portion 103 is inclined at a predetermined angle θ with respect to the horizontal direction. Thus, the kiln section 100 is configured such that the received predetermined raw material R10 is conveyed to the delivery port 102 along the central axis C10 while being in contact with the inner wall of the cylindrical section 103 . The angle θ can be selected from the range of -90 degrees to +90 degrees.

In the following description, the side relatively close to the raw material supply port 101 of the kiln section 100 may be referred to as the upstream side, and the side relatively close to the delivery port 102 may be referred to as the downstream side. That is, the kiln section 100 is configured such that the received predetermined raw material R10 is conveyed from the upstream side to the downstream side.

A feeder 140 is engaged with the raw material supply port 101 of the kiln section 100 shown in FIG. The feeder 140 rotatably supports the raw material supply port 101 side of the kiln section 100 . That is, the feeder 140 is a support section that supports the kiln section 100 . The feeder 140 receives the raw material R10 from a raw material inlet 141, which is an opening provided above, and guides the received raw material R10 to the raw material supply port 101. As shown in FIG. Further, feeder 140 supports first reaction auxiliary device 120 .

A kiln foot 150 is engaged with the delivery port 102 of the kiln section 100 via a bearing 104 . The kiln foot 150 rotatably supports the delivery port 102 side. That is, the kiln foot 150 is a support for supporting the kiln section 100 . The kiln foot 150 also has a reaction product outlet 151 through which the reaction product R11 delivered from the delivery port 102 is delivered. Furthermore, the kiln foot 150 supports the second reaction auxiliary device 130 .

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, for example, a heating device surrounding the cylindrical portion 103 in an intermediate region between the raw material supply port 101 and the delivery port 102 . Heating devices include any temperature-controllable heaters, such as sheath heaters, coil heaters, or ceramic heaters. Alternatively, the heating device may burn gas and circulate a heated fluid. Temperature controller 110 may include a controller for controlling the temperature of 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.

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 cylindrical section 103 . This support also has an auxiliary vessel for assisting the reaction of the raw material in the intermediate region of the kiln section 100 . The auxiliary device includes at least one of an agitator, a mixer, a pulverizer, a kneader, a conveyer (conveyor), a fluid injection port, a fluid suction port, and a scraper.

The first reaction auxiliary device 120 has a first support 121 and a stopper 122 as main components. The first support 121 is a beam-like structure that is supported by the feeder 140 and protrudes from the feeder 140 to the cylindrical portion 103 . The first support 121 holds the stopper 122 in the intermediate region of the tubular portion 103 .

The first reaction auxiliary device 120 will be further described with reference to FIG. FIG. 2 is a first cross-sectional view in the front direction of the reactor according to Embodiment 1. FIG. FIG. 2 is a sectional view of the section II-II shown in FIG. 1 observed from a direction parallel to the central axis C10.

The stopper 122 is a disk-shaped member having a main surface parallel to the surface perpendicular to the central axis C10. The outer peripheral portion of the stopper 122 has a gap between it and the inner wall of the cylindrical portion 103, which is large enough for the raw material R10 to pass through. Also, the stopper 122 has a function of receiving the ball 123 on the raw material supply port 101 side. A plurality of balls 123 are arranged upstream of the stopper 122 of the kiln section 100 and move freely as the cylindrical section 103 rotates. Also, the ball 123 has such a diameter that it cannot pass through the stopper 122 .

Accordingly, the first reaction auxiliary device 120 and the plurality of balls 123 have the function of a ball mill for pulverizing the raw material R10 inside the kiln section 100. That is, 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 the desired reaction.

Return to Figure 1 and continue the explanation. The second reaction auxiliary device 130 has a second support 131 and a scraper 132 . The second support 131 is a beam-shaped structure that is supported by the kiln foot 150 and protrudes from the kiln foot 150 to the cylindrical portion 103 . The second support 131 has a scraper 132 as an auxiliary device on the downstream side of the intermediate region of the tubular portion 103 . The scraper 132 is provided to scrape off the reaction product R11 produced in the intermediate region of the kiln section 100 when it adheres to the inner wall of the cylindrical section 103 .

The second reaction auxiliary device 130 will be further described with reference to FIG. FIG. 3 is a second cross-sectional view in the front direction of the reactor according to the first embodiment. FIG. 3 is a sectional view of the section III-III shown in FIG. 1 observed from a direction parallel to the central axis C10.

The scraper 132 is a flat member extending from the second support 131 toward the inner wall of the cylindrical portion 103 . The scraper 132 plays a role of stripping (scraping) the reaction product R11 adhering to the inner wall surface of the cylindrical portion 103 . Therefore, the gap between the tip of the scraper 132 and the inner wall of the cylindrical portion 103 is set to a distance that allows these substances adhering to the inner wall to be scraped off. As a result, the reaction product R11 adhering to the inner wall of the tubular portion 103 is separated from the inner wall and conveyed to the delivery port 102 .

By having the second reaction auxiliary device 130, the reaction device 10 can prevent the reaction product R11 from sticking to the inner wall of the cylindrical portion 103. Thereby, the reactor 10 can efficiently produce the desired reaction product.

Returning to Figure 1, the explanation continues. The drive device 160 has a motor and a driving force transmission portion 161 fitted to a drive shaft protruding from the motor. The driving device 160 rotates the kiln section 100 by transmitting the driving force of the motor to the driven section 106 via the driving force transmission section 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 processing performed by the reaction device 10 will be described with reference to FIG. FIG. 4 is a flow chart of the process (reaction product manufacturing method) executed by the reactor. The flow chart shown in FIG. 4 is executed using the reactor 10, for example, by a user who uses the reactor 10 to produce a reaction product.

First, the user prepares the reactor 10 including the kiln section 100 (step S11). The reactor 10 prepared by the user has the configuration described above.

Next, the user operates the reaction device 10 to cause 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).

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

Next, the user rotates the kiln unit 100 to convey the raw material R10 downstream (step S14). 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 first reaction auxiliary device 120 and the second reaction auxiliary device 130 to perform the reaction auxiliary operation (step S15). That is, the user causes the first reaction auxiliary device 120 to pulverize the raw material R10. Further, the user causes the second reaction auxiliary device 130 to scrape the reaction product R11 produced from the raw material R10.

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

The reaction product manufacturing method executed by the reactor 10 has been described above. According to the method described above, the reactor 10 receives the raw material R10 in the kiln section 100, promotes a predetermined reaction in the kiln section 100, and produces the reaction product R11. More specifically, the reactor 10 transports the received raw material R10 and pulverizes it by the first reaction auxiliary device 120 . Further, the reactor 10 exposes the pulverized raw material R10 to a predetermined temperature environment while tumbling and flowing downstream in the kiln section 100 to produce a reaction product R11. Furthermore, the reactor 10 scrapes the reaction product R11 in the cylindrical portion 103 by the second reaction auxiliary device 130 before the delivery port 102 . The reactor 10 then delivers the reaction product R11 through the delivery port 102 and discharges it through the reaction product outlet 151 .

The above-described method is shown along the flow from the production of the reaction product R11 from the raw material R10 by the reactor 10 to the delivery of the produced reaction product R11. However, the methods performed by reactor 10 are not constrained to the above order. For example, the reaction device 10 may perform the rotation operation of the kiln section 100 before step S12 or may be performed simultaneously with step S12.

Although the first embodiment has been described above, the reactor 10 according to the first embodiment is not limited to the configuration described above. The first reaction auxiliary device 120 and the second reaction auxiliary device 130 may have other auxiliary devices. Also, the reactor 10 may have only one of the first auxiliary reaction device 120 and the second auxiliary reaction device 130 . The first auxiliary reaction device 120 and the second auxiliary reaction device 130 may each have a plurality of auxiliary devices on its support.

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 cylindrical portion 103 . Also, 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 and integrated. That is, the reaction auxiliary device may have a support that is supported on the raw material supply port 101 side and the delivery port 102 side. Although a screw may be selected as a representative of the conveyer (conveyor) described above, it is not limited to a screw as long as it has a conveying function. For example, the carrier may be a pendulum paddle, a rotary paddle, or a belt with paddles that moves along the central axis C10. Furthermore, the conveyer is not limited to the one that conveys the raw material while contacting it, and may be one that conveys the raw material in a non-contact manner using a fluid, such as a fan or a jet nozzle.

In the first embodiment, the reactor 10, which is a rotary kiln, utilizes the space of the cylindrical portion 103 in the kiln portion 100 to continuously and efficiently feed the raw material R10 due to the configuration having the reaction auxiliary device as described above. A given reaction can be applied to produce the reaction product R11. Therefore, according to Embodiment 1, it is possible to provide a reaction apparatus or the like for efficiently producing a desired product.

<Embodiment 2>
Next, Embodiment 2 will be described. FIG. 5 is a side sectional view of the reactor 20 according to the second embodiment. The reactor 20 according to the second embodiment differs from the first embodiment in the mode of the reaction auxiliary device. Further, the reactor 20 differs from that of the first embodiment in the aspect of the temperature control device 110 .

The temperature control device 110 controls the temperature inside the cylinder by contacting the outer wall of the cylinder. The temperature control device 110 in this embodiment has a plurality of temperature control units along the stretching direction of the kiln unit 100 . That is, temperature control device 110 in the present embodiment has a plurality of temperature control regions that are different in the direction along central axis C10 in the intermediate region.

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 unit 110A is arranged 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 arranged downstream of the first temperature control section 110A and upstream of the third temperature control section 110C. The third temperature control section 110C is arranged downstream of the second temperature control section 110B.

The first temperature control section 110A, the second temperature control section 110B, and the third temperature control section 110C are set to different temperatures. For example, 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. The third temperature control section 110C controls the internal temperature of the kiln section 100 to, for example, 40 degrees. Thus, the temperature controller 110 can set different temperatures for different regions of the kiln section 100 . Thereby, the reactor 20 can promote or suppress a desired reaction depending on the region of the kiln section 100 .

The reaction device 20 in the present embodiment has a reaction auxiliary device 170 as a reaction auxiliary device. The reaction auxiliary device 170 has a support 171 , a stirrer 172 , a pulverizer 173 , a sprayer 174 , a carrier 175 , a speed reducer 176 , a driving force transmission section 177 and a support driving device 178 as main components.

The support 171 of the reaction auxiliary device 170 is rotatably supported by 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, one end of which is supported by a bearing 180 provided on the feeder 140, and the other of which is a bearing provided on the kiln foot 150. 180.

Also, the support 171 is connected to a support driving device 178 via a reduction gear 176 and a driving force transmission section 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 .

The support driving device 178 is a motor, and rotates the driving force transmission part 177 to transmit the driving force to the speed reducer 176 . The speed reducer 176 converts the force received from the driving force transmission unit 177 into a predetermined rotational speed by combining a plurality of gears, for example, and transmits the force to the support 171 .

The speed reducer 176 , the driving force transmission section 177 and the support driving device 178 are mechanisms for rotating the reaction auxiliary device 170 . The reaction auxiliary device 170 is supported so that the support 171 can rotate independently of the kiln section 100 . That is, the rotational direction and rotational speed of the kiln section 100 and the rotational direction and rotational speed of the support 171 may be the same or different. Specifically, for example, the kiln section 100 rotates about 0.1 to 10 times per minute, and the reaction auxiliary device 170 rotates about 0 to 500 times per minute. The rotation speed or rotation direction of the reaction auxiliary device 170 may change according to time.

The reaction auxiliary device 170 has a plurality of auxiliary devices along the extending direction of the support 171 . More specifically, the reaction auxiliary device 170 has a stirrer 172, a pulverizer 173, a sprayer 174 and a carrier 175 in order from the upstream side.

The stirrer 172 has a function of stirring the raw material R10 received from the raw material supply port 101. More specifically, the stirrer 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 orthogonal to the central axis C10, bends at right angles near the inner wall of the cylindrical portion 103, extends in a direction parallel to the central axis C10, and then bends again at right angles to connect to the support 171. . In the example shown in FIG. 5, the stirrer 172 has two of these bar-shaped members. Since the stirrer 172 is fixed to the support 171, the support 171 rotates to stir the raw material R10.

The pulverizer 173 has the function of pulverizing the raw material R10 stirred by the stirrer 172. The pulverizer 173 has a plurality of plate-shaped elliptical members having elliptical main surfaces. The elliptical member extends near the inner wall of the cylindrical portion 103 at its major diameter portion. Since the pulverizer 173 is fixed to the support 171, the support 171 rotates so that the bulk raw material R10 is sandwiched between the pulverizer 173 and the cylindrical portion 103 and pulverized.

The spray 174 discharges a predetermined fluid into the cylindrical portion 103 to bring the fluid into contact with the raw material R10. The support 171 has a fluid receiving port 174A at its upstream end and a pipe for sending the granules received therefrom to the spray 174 . The spray 174 ejects the fluid supplied through the fluid receiving port 174A from the 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. As shown in FIG. The fluid ejected by the spray 174 may be an inert gas or a predetermined gas for promoting reaction. Further, the fluid ejected by the spray 174 may contain fluid powder or liquid.

The conveyer 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 transporter 175 is a screw that transports the reaction product as the support 171 rotates. The conveyer 175 conveys the reaction product at a conveying speed corresponding to the pitch of the screw or the rotational speed of the support 171, for example.

Next, the relationship between the temperature control device 110 and the reaction auxiliary device 170 will be described. A stirrer 172 and a pulverizer 173 are installed in a region of the temperature control device 110 where the temperature is controlled by the first temperature control section 110A. A spray 174 is installed in a region where the temperature is controlled by the second temperature control section 110B. A transporter 175 is installed in a region where the temperature is controlled by the third temperature control section 110C.

That is, the reactor 20 degreases, agitates, and pulverizes the raw material R10 in a region 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 ejection port 174B in a region where the second temperature control section 110B controls the temperature to about 1000 degrees Celsius to promote the reaction of the raw material R10. Next, the reaction device 20 conveys the reaction product to the delivery port 102 in a region where the third temperature control section 110C controls the temperature to about 40 degrees Celsius.

As described above, the reaction device 20 can realize a desired process by linking the temperature control device 110 and the reaction auxiliary device 170 . In addition, the aspect of the auxiliary device which the reaction auxiliary device 170 has is not limited to the above example. For example, the configuration of the stirrer 172 is not limited to the above configuration as long as it has a function of stirring the raw material R10. The stirrer 172 may be a plate-like member or a pin-like member. In this case, the plate member is not limited to a flat plate, and may have unevenness, holes, or the like. Similarly, the shape of the pulverizer 173 may be such that the outer edge thereof has unevenness along the circumferential direction, for example. The pulverizer 173 may be a ball mill using the balls 123 shown in Embodiment 1 as a pulverizing medium, or a bead mill using beads smaller in diameter than the balls 123 as a pulverizing medium. It may be a rod mill that uses rods with short sides as a grinding medium. The reaction auxiliary device 170 may have one or more of the auxiliary devices described above.

<Embodiment 4>
Next, Embodiment 4 will be described with reference to FIG. FIG. 7 is a configuration diagram of a reaction system according to a fourth embodiment. The reaction system 2 shown in FIG. 7 has a granulator 210 and a reactor 20 as main components. In addition, the reactor 20 in the present embodiment is assumed to have a stirrer at least in the intermediate region as a reaction auxiliary device.

The granulator 210 applies pressure to the raw material, which is a granular material, to produce a granulated product. 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 efficiency of the reaction in the granulator 210, it is desirable that the granules have approximately the same size. 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 .

Upon receiving the granules at the raw material inlet 141 , the reactor 20 supplies the received granules to the kiln section 100 . The reaction device 20 applies a predetermined physical stimulus and a predetermined atmosphere to the received granules to produce a reaction product. More specifically, the reaction device 20 stirs the granules by the reaction auxiliary device 170 , blows out the gas for reaction and sucks the gas after the reaction, and applies predetermined heat by the temperature control device 110 . When the reaction product is produced, the reaction device 20 delivers the produced reaction product from the reaction product outlet 151 .

The fourth 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 20 whose atmosphere is controlled. Thereby, the reaction system 2 can continuously produce, for example, an oxide-based solid electrolyte or a sulfide-based solid electrolyte. That is, according to Embodiment 4, a desired reaction product can be produced efficiently and continuously.
