[0002] In some drying and dehydration processes, reactors are often used as equipment in the drying process.

[0042] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] like Figures 1 to 3 As shown, a drying reactor device according to an embodiment of the present application comprises a reactor body 100, which is used to provide a reaction chamber for drying reaction; wherein the reactor body 100 comprises at least one feed port 110 and one discharge port 120, and the feed port 110 and the discharge port 120 are located at two different ends of the reactor body 100; the drying reactor device further comprises a drying device 200, which is arranged in the reaction chamber, and the drying device 200 comprises a first drying section 210, a second drying section 220, a third drying section 230 and an air supply channel 240. 40, the first drying section 210, the second drying section 220 and the third drying section 230 are interconnected through an air supply channel 240, and the air supply channel supplies air to the interior of the drying device 200 through an external air source and releases gas into the reaction chamber through the first drying section 210, the second drying section 220 and the third drying section 230, and the air outlet areas of the first drying section 210, the second drying section 220 and the third drying section 230 increase successively, and the axis of the feed port 110 is parallel to the direction of gravity and its extension line intersects with the air outlet surface of the first drying section 210.

[0044] Specifically, the kettle body 100 includes a kettle body and a kettle cover, and the kettle body and the kettle cover are fixedly connected by a flange. The kettle body 100 has a containing space inside for providing a reaction chamber required for a drying reaction. A feed port 110 is provided on the kettle cover, and the feed port 110 is an electromagnetic feed port. When the electromagnetic switch is turned on, the feed port 110 is opened, and when the electromagnetic switch is turned off, the feed port 110 is closed. A discharge port 120 is also provided on the kettle body 100, and the discharge port 120 is arranged at the bottom of the kettle body. After the material is dehydrated and dried, it can be discharged from the kettle body 100 from the discharge port 120 at the bottom of the kettle body. In order to speed up feeding and discharging, multiple feed ports 110 and discharge ports 120 can also be provided on the kettle body or the kettle cover.

[0045] A drying device 200 is provided inside the kettle body 100, and the drying device 200 includes a plurality of drying components. In a specific embodiment, the drying device 200 includes a first drying section 210, a second drying section 220 and a third drying section 230, and the first drying section 210, the second drying section 220 and the third drying section 230 are connected through an air supply channel 240, that is, the air supply channel 240 introduces high-temperature dry inert gas into the first drying section 210, the second drying section 220 and the third drying section 230 of the drying device 200, and then releases the high-temperature dry inert gas into the reaction chamber at different positions through the air outlets 130 on the first drying section 210, the second drying section 220 and the third drying section 230, performs heat exchange with the material in the reaction chamber, and thereby converts the moisture in the material into water vapor and the excess inert gas is discharged out of the kettle body 100.

[0046] In a specific embodiment, the gas outlet areas of the first drying section 210, the second drying section 220, and the third drying section 230 increase in sequence, and the axis of the feed port 110 is parallel to the gravity direction and its extension line intersects with the gas outlet surface of the first drying section 210. That is, the gas outlet area of ​​the first drying section 210 is the smallest, and the first drying section 210 is arranged at the highest point in the reaction chamber relative to the second drying section 220 and the third drying section 230, that is, the first drying section 210 is closest to the feed port 110, and at the same time, the axis of the feed port 110 is parallel to the gravity direction and its extension line intersects with the gas outlet surface of the first drying section 210, and the feed port 110 is arranged above the first drying section 210 and its extension line intersects with the gas outlet surface of the first drying section 210, then the feed port 110 Under the action of gravity, the fed material will all fall from directly above the first drying section 210, and the inert gas discharged from the first drying section 210 will blow away the falling material in the first time, causing the material to move disorderly inside the kettle body, thereby lengthening the running path of the material inside the kettle body, allowing the material and the high-temperature inert gas to fully exchange heat and discharge moisture. The gas outlet surface mentioned here refers to the surface where the gas outlet 130 is located when the first drying section 210 discharges the inert gas from the inside.

[0047] More specifically, the ratio of the outlet area of ​​the first drying section 210 to the outlet area of ​​the second drying section 220 is in the range of 1 / 3 to 2 / 3, and the ratio of the outlet area of ​​the second drying section 220 to the outlet area of ​​the third drying section 230 is in the range of 1 / 2 to 3 / 4. Specifically, the ratio of the gas outlet area of ​​the first drying section 210 to the gas outlet area of ​​the second drying section 220 is 1 / 3, 1 / 2 and 2 / 3, and the ratio of the gas outlet area of ​​the second drying section 220 to the gas outlet area of ​​the third drying section 230 is 1 / 2, 2 / 3 and 3 / 4. In a specific embodiment, the projections of the first drying section 210, the second drying section 220 and the third drying section 230 on the same plane are all circular, and the projection circular area of ​​the first drying section 210 accounts for 1 / 3, 1 / 2 or 2 / 3 of the projection circular area of ​​the second drying section 220, and the projection circular area of ​​the second drying section 220 accounts for 1 / 2, 2 / 3 and 3 / 4 of the projection circular area of ​​the third drying section 230. The gas outlet areas of the first drying section 210, the second drying section 220 and the third drying section 230 are set to be gradually reduced. When the material enters the interior of the kettle body from the feed inlet 110, since it is set directly above the first drying section 210 , it will first be impacted by the high-temperature inert gas blown out from the first drying section 210. At this time, the material entering from the feed port 110 is blown away by the gas blown out from the first drying section 210, and a part of the water molecules inside it will quickly evaporate, and then fall from one side of the first drying section 210 into the area between the first drying section 210 and the second drying section 220 under the action of gravity. At this time, the dry hot air blown out from the second drying section 220 continues to blow away the material and a part of the water molecules inside it continues to evaporate, and the material continues to fall into the area between the second drying section 220 and the third drying section 230, and is further blown away and dried by the third drying section 230. After three rounds of drying, the material moves disorderly inside the reactor body and is finally discharged from the discharge port 120 after the reaction is completed. In the process of drying the material, three-level drying components with different blowing areas are set to quickly and thoroughly blow away and dry the material in the reactor.

[0048] In a specific embodiment, the first drying section 210 includes a first air inlet mechanism 211 and a first air outlet mechanism 212, one end of the first air inlet mechanism 211 is connected to the air supply channel 240, and the other end of the first air inlet mechanism 211 is connected to the internal space of the first air outlet mechanism 212, the outer surface of the first air outlet mechanism 212 is configured to be arc-shaped, and a plurality of first air outlet holes 213 are provided on the outer surface of the first air outlet mechanism 212, and the first air outlet holes 213 connect the internal space of the air outlet mechanism and the reaction chamber.

[0049] Specifically, one end of the first air inlet mechanism 211 is connected to the air supply channel, and the other end of the air supply channel extends out of the kettle body and is connected to the external air source, that is, the external air source transports the high-temperature inert gas to the inside of the first air inlet mechanism 211 through the air supply channel. The first air inlet mechanism 211 is connected to the first air outlet mechanism 212. The first air outlet mechanism 212 is constructed with an arc-shaped outer surface. The first air outlet mechanism 212 includes a plurality of first air outlet holes 213. The gas from the external air source entering the first drying section 210 is discharged into the inside of the kettle body from the first air outlet holes 213. The plurality of first air outlet holes 213 are evenly arranged on the first air outlet mechanism 212, and the diameter of the first air outlet holes 213 is The first air outlet 213 is the same as the first air outlet 213, and has an angle with the direction of gravity. The angle between the axis of the first air outlet 213 and the direction of gravity is in the range of 30° to 45°, specifically 30°, 35°, 40° or 45°. The first air outlet 213 with different angles is selected according to the moisture content (viscosity) of the material. The first air outlet 213 with a larger angle is selected for the material with a larger moisture content. The first air outlet 213 is provided with a certain angle with the direction of gravity, which effectively prevents the material from falling onto the air outlet surface of the first drying section 210 and flowing into the interior of the first drying section 210 from the first air outlet 213, thereby causing the first air outlet 213 to be blocked.

[0050] Similarly, the second drying section 220 includes a second air inlet mechanism 221 and a second air outlet mechanism 222, one end of the second air inlet mechanism 221 is connected to the air supply channel 240, and the other end of the second air inlet mechanism 221 is connected to the internal space of the second air outlet mechanism 222, the outer surface of the second air outlet mechanism 222 is configured to be arc-shaped, and a plurality of second air outlet holes 223 are provided on the outer surface of the second air outlet mechanism 222, and the second air outlet holes 223 connect the internal space of the air outlet mechanism and the reaction chamber.

[0051] Specifically, one end of the second air inlet mechanism 221 is connected to the air supply channel 240, and the other end of the air supply channel 240 is connected to the external air source, that is, the external air source transports the high-temperature inert gas to the inside of the second air inlet mechanism 221 through the air supply channel 240, and the second air inlet mechanism 221 is connected to the second air outlet mechanism 222, and the second air outlet mechanism 222 is configured to have an arc-shaped outer surface. The second air outlet mechanism 222 includes a plurality of second air outlet holes 223, and the gas introduced into the second drying section 220 by the external air source is discharged into the inside of the kettle body from the second air outlet holes 223. The plurality of second air outlet holes 223 are evenly arranged on the second air outlet mechanism 222. The diameters are all the same, and they all have an angle with the direction of gravity. The angle between the axis of the second air outlet 223 and the direction of gravity is in the range of 30° to 45°, specifically 30°, 35°, 40° or 45°. The second air outlet 223 with different angles is selected according to the moisture content (viscosity) of the material. The second air outlet 223 with a larger angle is selected for the material with a larger moisture content. The second air outlet 223 is set at a certain angle with the direction of gravity, which effectively prevents the material from falling into the air outlet surface of the second drying section 220 and flowing into the interior of the second drying section 220 from the second air outlet 223, thereby causing the second air outlet 223 to be blocked.

[0052] Similarly, the third drying section 230 includes a third air inlet mechanism 231 and a third air outlet mechanism 232, one end of the third air inlet mechanism 231 is connected to the air supply channel 240, and the other end of the third air inlet mechanism 231 is connected to the internal space of the third air outlet mechanism 232, the outer surface of the third air outlet mechanism 232 is constructed in an arc shape, and a plurality of third air outlet holes 233 are provided on the outer surface of the third air outlet mechanism 232, and the third air outlet holes 233 connect the internal space of the air outlet mechanism and the reaction chamber.

[0053] Specifically, one end of the third air inlet mechanism 231 is connected to the air supply channel 240, and the other end of the air supply channel 240 is connected to the external air source, that is, the external air source transports the high-temperature inert gas to the inside of the third air inlet mechanism 231 through the air supply channel 240, and the third air inlet mechanism 231 is connected to the third air outlet mechanism 232, and the third air outlet mechanism 232 is configured to have an arc-shaped outer surface. The third air outlet mechanism 232 includes a plurality of third air outlet holes 233, and the gas introduced into the third drying section 230 by the external air source is discharged into the inside of the kettle body from the third air outlet holes 233. The plurality of third air outlet holes 233 are evenly arranged on the third air outlet mechanism 232. The diameters of the third air outlet holes 233 are the same, and they all have an angle with the direction of gravity. The angle between the axis of the third air outlet hole 233 and the direction of gravity is in the range of 45° to 75°, specifically 45°, 50°, 60° or 75°. The third air outlet holes 233 with different angles are selected according to the moisture content (viscosity) of the material. The third air outlet holes 233 with a larger angle are selected for the material with a larger moisture content. The third air outlet holes 233 are set at a certain angle with the direction of gravity, which effectively prevents the material from falling into the air outlet surface of the third drying section 230 and flowing into the interior of the second drying section 220 from the third air outlet holes 233, thereby causing the third air outlet holes 233 to be blocked.

[0054] Since the moisture content of the material between the second drying section 220 and the third drying section 230 is relatively low, the third air outlet 233 on the third drying section 230 is more easily blocked by the dried material. Therefore, the angle between the axis of the third air outlet 233 and the direction of gravity is greater than the angle between the first air outlet 213 or the second air outlet 223 and the direction of gravity.

[0055] In a specific embodiment, the diameters of the first air outlet 213 of the first drying section 210, the second air outlet 223 of the second drying section 220, and the third air outlet 233 of the third drying section 230 increase successively, and the ratio of the diameter of the first air outlet 213 to the diameter of the second air outlet 223 is in the range of 1 / 3 to 1 / 2, and the ratio of the diameter of the second air outlet 223 to the diameter of the third air outlet 233 is in the range of 1 / 3 to 1 / 2. Since the distance between the first drying section 210 and the feed port 110 is the shortest, the moisture content of the material fed from the feed port 110 is the largest and its gravity is the largest. Therefore, the impact force required for the first drying section 210 to blow it away is the largest. Therefore, the diameter of the first air outlet 213 of the first drying section 210 is set to the smallest. According to Bernoulli's principle, the impact force of the wind blown out from the first air outlet 213 is the largest. Similarly, the moisture content of the material between the first drying section 210 and the second drying section 220 is greater than the moisture content of the material between the second drying section 220 and the third drying section 230. Therefore, the diameters of the first air outlet 213, the second air outlet 223, and the third air outlet 233 are increased successively, so that the material can be fully blown away in the reactor for rapid dehydration and drying.

[0056] In a specific embodiment, the drying reactor device further comprises a gas outlet 130, and the gas outlet 130 is used to discharge the gas in the drying reactor device, and the gas outlet 130 is arranged at the upper part of the reactor body 100. A gas-solid separator 131 is arranged in the gas outlet 130.

[0057] The gas outlet 130 is arranged on the kettle body 100 and the kettle cover. The gas outlet 130 is connected to the inside of the kettle body 100 to discharge the excess inert gas in the kettle body 100 and the water vapor separated from the material. In order to prevent the dried material from being discharged from the gas outlet 130 along with the inert gas and the water vapor separated from the material and then blocking the gas outlet 130, a gas-solid separator 131 is arranged at the gas outlet 130, which can smoothly discharge the inert gas and the water vapor separated from the material out of the reactor.

[0058] In a specific embodiment, the drying reactor device further includes a power device 300 , and the power device 300 is rotatably connected to the drying device 200 to provide the power required for the drying device 200 to rotate. Specifically, the power device 300 includes a servo motor, a rotating shaft and a coupling. The servo motor is fixed to the kettle body through a motor base. The output shaft of the servo motor is connected to the rotating shaft through a coupling. The rotating shaft extends into the kettle body 100. An air supply channel 240 is provided inside the rotating shaft. The rotating shaft serves as a fixed support for the first drying section 210, the second drying section 220 and the third drying section 230. At the same time, the rotating shaft supplies air to the first drying section 210, the second drying section 220 and the third drying section 230 through the air supply channel 240 inside it. At the same time, the rotating shaft rotates driven by the servo motor and then drives the first drying section 210, the second drying section 220 and the third drying section 230 to rotate. The first drying section 210, the second drying section 220 and the third drying section 230 supply air to the kettle body 100 while rotating themselves, which can make the air outlet of the first drying section 210, the second drying section 220 and the third drying section 230 more uniform, and can efficiently dry and dehydrate the material.

[0059] In a specific embodiment, the drying reactor device further includes a spray device 400, one end of which is connected to an external spray device and the other end extends into the reaction chamber, and the spray device 400 includes a spray head 410, and the spray head 410 is provided with a plurality of spray holes 420. The end of the spray device 400 away from the spray head 410 is connected to an external gas source through a pipeline.

[0060] The spray device 400 is fixed on the inner wall of the kettle body 100. Specifically, it is fixedly connected to the inner wall of the kettle cover, and its inlet end is connected to the external spray equipment. The spray device 400 includes a spray head 410, and the spray head 410 is provided with a plurality of spray holes 420. The spray holes 420 can spray the liquid or gas in the spray device 400 at a high speed, so as to clean the inner wall of the reactor after the reaction of the reactor is completed. Since one end of the spray device 400 is also connected to an external gas source, a solenoid valve is provided inside the spray device 400. When the reactor is drying, the solenoid valve is in an open state. At this time, the external gas source sprays high-temperature gas into the reactor body 100 through the spray head 410. In the process of feeding the reactor into the reactor body 100, since the first drying section 210 always blows air upward, the raw materials at the feed port 110 are blown away, and part of the raw materials may enter the spray device 400 from the spray hole 420. At this time, since the spray device 400 sprays air outward, this phenomenon is avoided, and the spray hole 420 is effectively prevented from being blocked.

[0061] In a specific embodiment, the drying reactor device further includes an external gas source, which is connected to the drying device 200 and / or the spraying device 400 through a pipeline. Specifically, the external gas source includes a gas source bottle, which is an inert gas such as nitrogen, and the external gas source bottle is connected to the gas supply channel 240 through a pipeline, and a heating wire is also provided on the pipeline for heating the gas in the pipeline.

[0062] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
