Description

Technical Field

[0001] The present application relates to the technical field of pharmaceutical production equipment, and more specifically, to a drying device for veterinary drug production. Background Art

[0002] Veterinary drugs refer to drugs used to prevent, treat, diagnose animal diseases or improve animal health. In the process of veterinary drug production, in order to facilitate the storage of veterinary drugs, dryers or drying machines are used to remove moisture from granular or powdered drugs, thereby increasing the shelf life and stability of veterinary drugs. Therefore, the drying process in the veterinary drug production process is crucial to the production of veterinary drugs. In the veterinary drug drying equipment of the prior art, a hot air delivery pipeline is used to convey dry hot air into the drying cylinder through the side wall of the drying cylinder, so that different positions of the veterinary drugs are heated unevenly, affecting the drying time of the veterinary drugs, thereby affecting the drying efficiency. In addition, the hot air input at a single point such as the side wall of the drying cylinder is used, resulting in a poor drying effect on the drugs in the cylinder. Summary of the invention

[0003] In view of this, the present application provides a drying device for veterinary drug production to solve the technical problems of poor drying efficiency and effect of veterinary drug drying equipment in the prior art.

[0006] A rotating tube, the rotating tube is rotatably mounted on the upper cover and penetrates downward from the upper cover into the interior of the drying tank along the vertical center axis of the drying tank, a stirring plate is connected to the outer side of the peripheral wall of the tube section of the rotating tube located inside the drying tank, a plurality of first through holes are formed on the stirring plate, the first through holes penetrate the stirring plate along the thickness direction of the stirring plate, and air guide through holes are formed on the peripheral wall of the tube section of the rotating tube located inside the drying tank, the air guide through holes are formed in a plurality of groups at intervals along the axial direction of the rotating tube, and each group includes a plurality of air guide through holes arranged at intervals along the circumferential direction of the rotating tube;

[0007] A driving system is drivingly connected to the section of the rotating tube located above the upper cover to drive the rotating tube to rotate;

[0008] A dry hot air generating system, comprising a hot air generating source, a first heat conducting pipe and a second heat conducting pipe connected to the hot air generating source, the first heat conducting pipe being inserted into the upper port of the rotating pipe, and the second heat conducting pipe being communicated to the air inlet hole.

[0009] Further, the stirring plate is connected to the rotating pipe through an air guide pipe. The length direction of the stirring plate is consistent with the radial direction of the rotating pipe, and the width direction of the stirring plate is consistent with the axial direction of the rotating pipe. An air guide cavity is formed inside the stirring plate. The air guide cavity is communicated with the inside of the rotating pipe through the air guide pipe. The drying device further includes a sliding pipe slidably arranged in the first through hole along the thickness direction of the stirring plate. The head of the sliding pipe extends out of the first through hole, and the diameter of the head of the sliding pipe is larger than the diameter of the first through hole. The sliding pipe is a hollow pipe with both ends penetrating. An air passage is arranged on the pipe wall of the sliding pipe. The sliding pipe is elastically matched with the inner wall of the stirring plate so that the sliding pipe is in a first position when the head of the sliding pipe is not subjected to an external force. In the first position, the pipe wall of the sliding pipe isolates the air guide cavity from the outside of the stirring plate. After the head of the sliding pipe is pressed to move a predetermined distance towards the first through hole, the air passage communicates the air guide cavity with the lumen of the sliding pipe.

[0010] Further, a plurality of the air passages are arranged around the axial direction of the sliding pipe. Each of the air passages obliquely extends from the outer wall surface of the sliding pipe towards the head of the sliding pipe to the inner wall surface of the sliding pipe. In the first position, the port of the air passage located on the outer wall surface of the sliding pipe is blocked by the inner wall of the stirring plate. After the head of the sliding pipe is pressed to move a predetermined distance towards the first through hole, the port of the air passage located on the outer wall surface of the sliding pipe is communicated with the air guide cavity.

[0011] Further, an installation groove is arranged on the inner side of the wall body of the stirring plate away from the head of the sliding pipe. An outer peripheral ring platform is arranged at the middle part of the sliding pipe in the air guide cavity. A spring is arranged in the installation groove.

The length direction of the vibrating plate is consistent with the radial direction of the rotating pipe, and the width direction of the vibrating plate is consistent with the axial direction of the rotating pipe. The vibrating plate extends toward the rotating pipe along the radial direction of the rotating pipe and is spaced from the rotating pipe. The stirring and impacting mechanism includes a first working state and a second working state. In the first working state, the stirring and impacting mechanism never contacts the vibrating plate when rotating with the rotating pipe. In the second working state, the stirring and impacting mechanism impacts the vibrating plate when rotating with the rotating pipe and passing by the vibrating plate.

[0013] Further, the stirring and impacting mechanism includes a support block, a spring piece and an impact piece. The support block is connected to the outer side of the peripheral wall of the rotating pipe. A hollow portion is formed in the middle of the support block. Slots are respectively arranged at both ends of the hollow portion along the radial direction of the rotating pipe. The slots include a first slot adjacent to the rotating pipe and a second slot away from the rotating pipe. The first end of the spring piece is inserted into the first slot, and the second end of the spring piece is inserted into the second slot. The impact piece includes an inserting piece portion and an impact portion. The inserting piece portion is inserted into a corresponding inserting cavity in the support block in the vertical direction. The inserting cavity is communicated with the second slot. The impact portion extends out of the support block. A first wedge surface is arranged at the second end of the spring piece, and the first wedge surface gradually inclines upward toward the rotating pipe along the radial direction of the rotating pipe. A second wedge surface is formed on the side surface of the inserting piece portion, and the second wedge surface is in inclined wedge fit with the first wedge surface. When the spring piece is in an extended state, the inserting piece portion is supported at a first height through the inclined wedge fit, so that the height of the impact portion is higher than the upper end surface height of the corresponding vibrating plate. When the spring piece bends, the second end of the spring piece moves toward the rotating pipe, so that the inserting piece portion drops to a second height under its own gravity through the inclined wedge fit, so as to drive the impact portion to drop to a height lower than the upper end surface height of the corresponding vibrating plate.

[0014] Further, a buffer air channel is formed in the support block. A first port of the buffer air channel is communicated with the lumen of the rotating pipe, and a second port of the buffer air channel leads to the inserting cavity. When the inserting piece portion is at the first height, the inserting piece portion blocks the second port of the buffer air channel. When the inserting piece portion is at the second height, the second port of the buffer air channel is communicated with the inserting cavity.

[0015] Further, an extension block extending away from the rotary tube is connected to the upper end of the insert part. The impact part is an impact shaft rotatably installed in the extension block. The axis of the impact shaft is parallel to the axis of the rotary tube. The lower end of the impact shaft is used to impact the upper end of the vibration plate in the second working state.

[0016] Further, the drive system includes a motor and a gearbox installed on the upper cover. A first bevel gear is fixedly connected to the outer side of the pipe section of the rotary tube extending out of the upper cover. A second bevel gear meshing with the first bevel gear is arranged on the output shaft of the gearbox. The output shaft of the motor is drivingly connected to the input shaft of the gearbox.

[0017] Further, the hot gas generation source includes a hot air blower installed on the upper cover. Both the first heat conduction pipe and the second heat conduction pipe are connected to the output end of the hot air blower. The drying device further includes a feed hopper arranged on the upper cover and a discharge pipeline arranged at the bottom of the drying tank body.

[0018] Compared with the prior art, in the drying device for veterinary drug production provided by the present invention, the drying hot gas generation system can introduce drying hot gas into the rotary tube through the first heat conduction pipe. On the one hand, the hot gas ejected from the plurality of air guide through holes in the axial and circumferential directions of the rotary tube dries the veterinary drug particles in the drying tank body at the position of the central axis of the drying tank body, forming a multi-point hot air introduction along the axial and circumferential directions of the rotary tube at the central axis position of the drying tank body. On the other hand, it can make the drying hot gas enter the drying tank body through the air inlet holes on the side wall of the drying tank body through the second heat conduction pipe to dry the veterinary drug particles in the drying tank body, forming a form of introducing drying hot air at multiple places on the outer periphery and the central axis of the drying tank body, directly hot air blowing and drying the veterinary drug particles at different positions in the drying tank body, greatly increasing the efficiency and effect of the drying operation of the veterinary drug particles in the drying tank body. In addition, a plurality of first through holes are formed on the stirring plate. While stirring the veterinary drug particles by rotating with the rotary tube, the veterinary drug particles also form a screening flow movement through the first through holes, which also improves the efficiency and effect of the drying operation of the veterinary drug particles.

[0036] See Figures 1 to 5 、 Figure 11 and Figure 12 , the present invention provides a drying device for veterinary drug production. Among them, the drying device for veterinary drug production includes:

[0037] A drying tank body 100 and an upper cover 1 provided at the upper end of the drying tank body 100. An air inlet hole 101 is formed in the lower part of the side wall of the drying tank body 100, and an air outlet hole 102 is formed in the upper part of the side wall of the drying tank body 100;

[0038] The rotating tube 2 is rotatably mounted on the upper cover 1 and penetrates downward from above the upper cover 1 along the vertical central axis of the drying tank body 100 into the interior of the drying tank body 100. A stirring plate 200 is connected to the outer side of the peripheral wall of the tube section of the rotating tube 2 located inside the drying tank body 100. A plurality of first through holes 201 are formed on the stirring plate 200, and the first through holes 201 penetrate through the stirring plate 200 in the thickness direction of the stirring plate 200. Air guiding through holes 21 are formed on the peripheral wall of the tube section of the rotating tube 2 located inside the drying tank body 100. A plurality of groups of air guiding through holes 21 are formed at intervals along the axial direction of the rotating tube 2, and each group includes a plurality of air guiding through holes 21 arranged at intervals in the circumferential direction of the rotating tube 2;

[0039] A drive system is in transmission connection with the section of the rotating tube 2 located above the upper cover 1 to drive the rotating tube 2 to rotate;

[0040] A drying hot air generating system includes a hot air generating source and a first heat conducting tube 3 and a second heat conducting tube 4 connected to the hot air generating source. The first heat conducting tube 3 is inserted into the upper port of the rotating tube 2, and preferably, a slidable sealing contact is formed between the outer peripheral surface of the first heat conducting tube 3 and the inner wall surface of the rotating tube 2. The second heat conducting tube 4 is communicated to the air inlet hole 101.

[0041] In the drying device for veterinary drug production provided by the present invention, the drying hot air generating system can introduce drying hot air into the rotating tube 2 through the first heat conducting tube 3. On the one hand, the hot air ejected from the air guiding through holes 21 in the axial and circumferential directions of the rotating tube 2 dries the veterinary drug particles in the drying tank body 100 at the position of the central axis of the drying tank body 100, forming a multi-point hot air introduction along the axial and circumferential directions of the rotating tube 2 at the central axis position of the drying tank body 100. On the other hand, the drying hot air can enter the drying tank body 100 through the air inlet hole 101 on the side wall of the drying tank body 100 through the second heat conducting tube 4 to dry the veterinary drug particles in the drying tank body 100, forming a form of introducing drying hot air at multiple places on the outer periphery and the central axis of the drying tank body 100, directly hot air blowing and drying the veterinary drug particles at different positions in the drying tank body 100, greatly increasing the efficiency and effect of the drying operation of the veterinary drug particles in the drying tank body 100. In addition, a plurality of first through holes 201 are formed on the stirring plate 200. While stirring the veterinary drug particles along with the rotation of the rotating tube 2, the veterinary drug particles also form a screening flow movement through the first through holes 201, which also improves the efficiency and effect of the drying operation of the veterinary drug particles.

[0042] According to an embodiment of the present application, the stirring plate 200 is connected to the rotating tube 2 through the air duct 5. The length direction of the stirring plate 200 is consistent with the radial direction of the rotating tube 2, and the width direction of the stirring plate 200 is consistent with the axial direction of the rotating tube 2. An air guide cavity 205 is formed in the stirring plate 200, and the air guide cavity 205 is communicated with the inside of the rotating tube 2 through the air duct 5. The drying device further includes a sliding tube 202 slidably disposed in the first through hole 201 along the thickness direction of the stirring plate 200. The head 203 of the sliding tube 202 extends out of the first through hole 201. The diameter of the head 203 of the sliding tube 202 is larger than the diameter of the first through hole 201. The head of the sliding tube 202 is in a disc shape. The sliding tube 202 is a hollow tube with both ends penetrating. An air passage 204 is provided on the tube wall of the sliding tube 202. The sliding tube 202 is elastically matched with the inner wall of the stirring plate 200 so that when no external force acts on the head 203 of the sliding tube 202, the sliding tube 202 is in the first position. In the first position, the tube wall of the sliding tube 202 isolates the air guide cavity 205 from the outside of the stirring plate 200. After the head 203 of the sliding tube 202 is pressed and moves a predetermined distance towards the first through hole 201, the air passage 204 communicates the air guide cavity 205 with the lumen of the sliding tube 202. Therefore, when the rotating tube 2 moves along such that the veterinary drug particles installed on the stirring plate 200 face the veterinary drug particles in the drying tank 100, if the humidity of the veterinary drug particles on one side of the head 203 of the sliding tube 202 on the stirring plate 200 is too high and causes agglomeration, the resistance generated by the agglomerated veterinary drug particles to the head 203 of the rotating tube 2 increases, forcing the head 203 of the sliding tube 202 to be pressed by the agglomerated veterinary drug particles to overcome the elastic mating force between the sliding tube 202 and the inner wall of the stirring plate 200 and move a predetermined distance towards the first through hole 201 to reach the second position, so that the air passage 204 communicates the air guide cavity 205 with the lumen of the sliding tube 202. In this way, the hot air entering the air guide cavity 205 from the inside of the rotating tube 2 will reach the lumen of the sliding tube 202 through the air passage 204 and be ejected from both ends of the sliding tube 202 (mainly the port at one end of the head 203), thereby directly blowing hot air to the agglomerated veterinary drug particles (and unagglomerated veterinary drug particles) near the sliding tube 202, so as to quickly dry and separate the agglomerated veterinary drug particles, further improving the drying efficiency and drying effect of the veterinary drug particles.

[0043] According to a preferred embodiment of the present application, a plurality of air channels 204 are arranged axially around the sliding tube 202, and each air channel 204 extends obliquely from the outer wall of the sliding tube 202 toward the head 203 of the sliding tube 202 to the inner wall of the sliding tube 202, so that it can be obliquely aligned with the port of the head 203 of the sliding tube 202, so as to facilitate the rapid spraying of hot air from the port of the head 203 of the sliding tube 202 to the veterinary drug particles bonded to the head 203 of the sliding tube 202. In the first position, the port of the air channel 204 located on the outer wall of the sliding tube 202 is blocked by the inner wall of the stirring plate 200. After the head 203 of the sliding tube 202 is pressed toward the first through hole 201 for a predetermined distance, the port of the air channel 204 located on the outer wall of the sliding tube 202 is connected to the air guide cavity 205.

[0044] According to one embodiment of the present application, a mounting groove 206 is provided on the inner side of the wall of the stirring plate 200 away from the head 203 of the sliding tube 202, and the sliding tube 202 is provided with an outer peripheral ring platform 207 in the air guide cavity 205, and a spring 208 is provided in the mounting groove 206. The spring 208 is sleeved on the sliding tube 202, and one end of the spring 208 abuts against the outer peripheral ring platform 207, and the other end of the spring 208 abuts against the bottom surface of the mounting groove 206. The spring 208 can be selected according to actual needs. The spring 208 with different elastic forces should be adapted to the resistance of the veterinary drug particles to the head 203 of the sliding tube 202. For example, when the humidity of the veterinary drug particles is low (more dispersed), it is not enough to press the head 203 of the sliding tube 202 to move toward the first through hole 201. When the humidity of the veterinary drug particles reaches a certain level (the veterinary drug particles are bonded to a certain level), the resistance to the head 203 of the sliding tube 202 is sufficient to press the head 203 of the sliding tube 202 to move toward the first through hole 201.

[0045] According to a preferred embodiment of the present application, the head 203 of the sliding tube 202 forms a tapered surface 209 that gradually decreases toward the stirring plate 200, so that when the head 203 of the sliding tube 202 moves toward the first through hole 201 (towards the stirring plate 200), the veterinary drug particles between the head 203 (tapered surface 209) and the stirring plate 200 can be separated, making the movement of the sliding tube 202 smoother.

[0046] See also Figures 1 to 3 as well as Figures 6 to 10, according to an embodiment of the present invention, the drying device further includes a stirring and impacting mechanism 300 disposed on the outer side of the circumferential wall of the pipe section of the rotating pipe 2 located inside the drying tank 100, and a vibration plate 6 disposed on the inner side wall surface of the drying tank 100. The vibration plate 6 is formed with a plurality of second through holes 61. The second through holes 61 penetrate through the stirring plate 200 in the thickness direction of the stirring plate 200. The length direction of the vibration plate 6 is consistent with the radial direction of the rotating pipe 2, and the width direction of the vibration plate 6 is consistent with the axial direction of the rotating pipe 2. The vibration plate 6 extends toward the rotating pipe 2 along the radial direction of the rotating pipe 2 and is spaced from the rotating pipe 2. The stirring and impacting mechanism 300 includes a first working state and a second working state. In the first working state, the stirring and impacting mechanism 300 never contacts the vibration plate 6 when rotating with the rotating pipe 2. In the second working state, the stirring and impacting mechanism 300 impacts the vibration plate 6 when rotating with the rotating pipe 2 and passing by the vibration plate 6. In this embodiment, the second working state can be triggered as needed, so that the stirring and impacting mechanism 300 impacts the vibration plate 6 when rotating with the rotating pipe 2 and passing by the vibration plate 6, thereby causing the vibration plate 6 to vibrate and driving the veterinary drug particles near the vibration plate 6 to vibrate. In this way, the gaps between the veterinary drug particles can be suddenly increased, and the hot air blowing and drying effect can be improved.

[0047] According to a specific embodiment of the present application, the stirring and impacting mechanism 300 includes a support block 301, a spring piece 302 and an impacting member. The support block 301 is connected to the outer side of the circumferential wall of the rotating tube 2. A hollow portion 303 is formed in the middle of the support block 301. Slots are respectively arranged at both ends of the hollow portion 303 along the radial direction of the rotating tube 2. The slots include a first slot 304 adjacent to the rotating tube 2 and a second slot 317 away from the rotating tube 2. The first end of the spring piece 302 is inserted into the first slot 304, and the second end of the spring piece 302 is inserted into the second slot 317. The impacting member includes an inserting piece portion 305 and an impacting portion 306. The inserting piece portion 305 is inserted into a corresponding inserting piece cavity 307 in the support block 301 along the vertical direction. The inserting piece cavity 307 is communicated with the second slot 317. The impacting portion 306 extends out of the support block 301. A first wedge surface 308 is provided at the second end of the spring piece 302. The first wedge surface 308 gradually slopes upward toward the rotating tube 2 along the radial direction of the rotating tube 2. A second wedge surface 309 is formed on the side surface of the inserting piece portion 305. The second wedge surface 309 is in inclined wedge fit with the first wedge surface 308. When the spring piece 302 is in an extended state, the inserting piece portion 305 is supported at a first height through the inclined wedge fit, so that the height of the impacting portion 306 is higher than the upper end surface height of the corresponding vibrating plate 6. When the spring piece 302 is bent, the second end of the spring piece 302 moves toward the rotating tube 2, so that the inserting piece portion 305 drops to a second height under its own gravity through the inclined wedge fit, so as to drive the impacting portion 306 to drop to a height lower than the upper end surface height of the corresponding vibrating plate 6. Preferably, there is a gap between the upper and lower ends of the spring piece 302 and the support block 301. This part of the gap can allow veterinary drug particles to flow through, increasing the stirring effect of the veterinary drug particles and further increasing the drying effect. In this embodiment, the triggering principle of the second working state is as follows: If the rotating tube 2 rotates and the humidity of the veterinary drug particles near the side where the spring piece 302 moves against the veterinary drug particles is too high, resulting in adhesion, the resistance generated by the adhered veterinary drug particles to the spring piece 302 increases, causing the spring piece 302 to bend. Thus, the inserting piece portion 305 drops to the second height under its own gravity through the inclined wedge fit, so as to drive the impacting portion 306 to drop to a height lower than the upper end surface height of the corresponding vibrating plate 6. Spring pieces 302 with different elastic forces can be selected according to actual needs, and they should be appropriately matched with the resistance of the veterinary drug particles to the spring piece 302. For example, when the humidity of the veterinary drug particles is relatively low (more dispersed), it is not enough to push the spring piece 302 to bend. When the humidity of the veterinary drug particles reaches a certain level (when the veterinary drug particles are adhered to a certain degree), it can push the spring piece 302 to bend.

[0048] According to a specific embodiment of the present application, the support block 301 forms a buffer air passage 310. The first port of the buffer air passage 310 communicates with the lumen of the rotating tube 2, and the second port of the buffer air passage 310 leads to the insert cavity 307. When the insert portion 305 is at the first height, the insert portion 305 blocks the second port of the buffer air passage 310. When the insert portion 305 is at the second height, the second port of the buffer air passage 310 communicates with the insert cavity 307. In this embodiment, when the insert portion 305 is at the second height, the second working state is triggered, and the impact portion 306 performs an impact operation. At this time, since the second port of the buffer air passage 310 communicates with the insert cavity 307, the hot air in the buffer air passage 310 quickly surrounds the insert portion 305, which can relieve the rigid contact between the insert portion 305 and the support block 301, and avoid excessive transmission of the reaction force of the vibrating plate on the impact portion 306 when the impact portion 306 impacts the vibrating plate 6 to the support block 301, and then to the rotating tube 2. That is, the reaction force of the vibrating plate 6 during vibration on the rotating tube 2 is relieved, and the rotation stability and service life of the rotating tube 2 are improved.

[0049] In this embodiment, specifically, two buffer air passages 310 can be provided. The two buffer air passages 310 are respectively located on the upper and lower sides of the hollow portion 303. Two rubber ring plugs 311 are sleeved on the insert portion 305. The side surface of the rubber ring plug 311 forms a ring plug inclined surface 318 that narrows upward, and the second port of the buffer air passage 310 forms a port inclined surface that cooperates with the inclined surface of the rubber ring plug 311 (substantially in a rectangular ring shape and matching the rectangular cross-section of the insert portion 305). When the insert portion 305 is supported at the first height by wedge fit, the ring plug inclined surface of the rubber ring plug 311 presses against the port inclined surface of the second port of the buffer air passage 310 to seal the second port.

[0050] According to an embodiment of the present application, an extension block 312 extending away from the rotating tube 2 is connected to the upper end of the insert portion 305. The impact portion 306 is an impact shaft connected to the lower part of the end of the extension block 312 away from the insert portion 305. The lower end of the impact shaft is used to impact the upper end of the vibrating plate 6 in the second working state.

[0051] According to another embodiment of the present application, an extension block 312 extending away from the rotating tube 2 is connected to the upper end of the insert portion 305. The impact portion 306 is an impact shaft rotatably installed in the extension block 312. The axis of the impact shaft is parallel to the axis of the rotating tube 2. The lower end of the impact shaft is used to impact the upper end of the vibrating plate 6 in the second working state. In this embodiment, when the impact shaft impacts the upper end of the vibrating plate 6, it is frictionally rotated by the vibrating plate 6, so that a part of the reaction force can be converted into the rotational potential energy of the impact shaft, which can relieve the rigid reaction force transmitted from the impact shaft to the insert portion 305, and ultimately relieve the reaction force of the vibrating plate 6 during vibration on the rotating tube 2.

[0052] According to a preferred embodiment of the present application, multiple loose wires 313 are inserted at the upper end of the impact shaft. On the one hand, when the stirring and impact mechanism 300 rotates with the rotating tube 2, the loose wires 313 also rotate around the rotating tube 2, which can loosen and disturb the veterinary drug particles in the drying tank 100, increasing the drying effect. On the other hand, as mentioned in the above embodiment, when the impact shaft impacts the upper end of the vibration plate 6, it is frictionally rotated by the vibration plate 6, so that the loose wires 313 are also driven to rotate around the impact shaft, which further increases the loosening effect of the loose wires 313 on the veterinary drug particles.

[0053] According to a specific implementation of the present application, multiple wire passing channels 314 penetrating radially along the impact shaft are formed at the upper end of the impact shaft. The loose wires 313 pass through the corresponding wire passing channels 314. One or more loose wires 313 can pass through one wire passing channel 314. A threaded opening is formed at the upper end face of the impact shaft. A groove 315 is formed below the wire passing channels 314 in the impact shaft. A threaded plug 316 is installed in the threaded opening. The threaded plug 316 can press the loose wires 313 against the groove 315, so that the loose wires 313 are fixed at the upper end of the impact shaft.

[0054] In addition, the drive system includes a motor 7 and a gearbox 8 installed on the upper cover 1. A first bevel gear 9 is fixedly connected to the outer side of the pipe section of the rotating tube 2 extending out of the upper cover 1. A second bevel gear 12 meshing with the first bevel gear 9 is provided on the output shaft of the gearbox 8. The output shaft of the motor 7 is drivingly connected to the input shaft of the gearbox 8. A bearing is provided at the through-fit portion of the rotating tube 2 and the upper cover 1.

[0055] According to an embodiment of the present application, the heat gas generation source includes a hot air blower 14 installed on the upper cover 1. Both the first heat conduction tube 3 and the second heat conduction tube 4 are connected to the output end of the hot air blower 14. The drying device further includes a feed hopper 15 provided on the upper cover 1 and a discharge pipeline 16 provided at the bottom of the drying tank 100. The feed hopper 15 and the discharge pipeline 16 respectively lead to the inside of the drying tank 100, and on-off valves can be provided on the feed hopper 15 and the discharge pipeline 16. In this embodiment, the first heat conduction tube 3 and the second heat conduction tube 4 share the hot air of the same hot air blower 14. However, as other embodiments, hot air blowers 14 can also be independently provided for the first heat conduction tube 3 and the second heat conduction tube 4 respectively.

[0056] In addition, multiple support columns 17 can be connected below the drying tank 100. The bottom of the drying tank 100 preferably forms a tapered bottom plate 103 that gradually narrows downward. The discharge pipeline 16 is connected below the tip of the tapered bottom plate 103. An air outlet pipe 18 can be connected at the air outlet 102. The air outlet pipe 18 can discharge the gas after passing through the drying box. The drying box can dry the water vapor discharged from the drying tank 100.

[0057] It should be noted that the above embodiments only represent the preferred embodiments of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, such as combining different features in each embodiment, etc. These should all fall within the protection scope of the present application.
