[0021] See also Figures 1 to 5 , Fig.11 and Fig.12 The present invention provides a drying device for veterinary drug production, wherein the drying device for veterinary drug production comprises: A drying tank body 100 and an upper cover 1 arranged at the upper end of the drying tank body 100, an air inlet 101 is formed at the lower part of the side wall of the drying tank body 100, and an air outlet 102 is formed at the upper part of the side wall of the drying tank body 100; A rotating tube 2, which is rotatably mounted on the upper cover 1 and penetrates downward from the upper cover 1 into the interior of the drying tank body 100 along the vertical center axis 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. The first through holes 201 penetrate the stirring plate 200 along the thickness direction of the stirring plate 200. An air guide through hole 21 is formed on the peripheral wall of the tube section of the rotating tube 2 located inside the drying tank body 100. The air guide through holes 21 are formed in a plurality of groups at intervals along the axial direction of the rotating tube 2, and each group includes a plurality of air guide through holes 21 arranged at intervals along the circumferential direction of the rotating tube 2. A driving system is drivingly connected to the section of the rotating tube 2 located above the upper cover 1 to drive the rotating tube 2 to rotate; The drying hot air generating system comprises a hot air generating source and a first heat conducting pipe 3 and a second heat conducting pipe 4 connected to the hot air generating source. The first heat conducting pipe 3 is inserted into the upper port of the rotating tube 2, and the outer peripheral surface of the first heat conducting pipe 3 preferably forms a slidable sealed contact with the inner wall surface of the rotating tube 2. The second heat conducting pipe 4 is connected to the air inlet 101.

[0022] 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 pipe 3. On the one hand, the hot air ejected from the multiple air conducting holes 21 in the axial and circumferential directions of the rotating tube 2 is used to perform hot air drying on the veterinary drug particles in the drying tank body 100 at the position of the central axis of the drying tank body 100, thereby forming hot air introduction at multiple points along the axial and circumferential directions of the rotating tube 2 at the position of the central axis of the drying tank body 100. On the other hand, the drying hot air can enter the drying tank body 100 through the second heat conducting pipe 4 from the air inlet 101 on the side wall of the drying tank body 100. The drying tank body 100 performs hot air drying on the veterinary drug particles in the drying tank body 100, forming a form of multiple dry hot air introduction at the outer peripheral side and the central axis of the drying tank body 100, and directly performing hot air blowing drying on the veterinary drug particles at different positions in the drying tank body 100, which greatly increases 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 the veterinary drug particles are rotated and stirred with the rotating tube 2, the veterinary drug particles also form a screening flow motion through the first through holes 201, which also improves the efficiency and effect of the drying operation of the veterinary drug particles.

[0023] According to one embodiment of the present application, the stirring plate 200 is connected to the rotating tube 2 through the air guide tube 5, the length direction of the stirring plate 200 is consistent with the radial direction of the rotating tube 2, the width direction of the stirring plate 200 is consistent with the axial direction of the rotating tube 2, and an air guide cavity 205 is formed in the stirring plate 200. The air guide cavity 205 is connected to the inside of the rotating tube 2 through the air guide tube 5. The drying device also includes a sliding tube 202 that is slidably arranged in the first through hole 201 along the thickness direction of the stirring plate 200, and the head 203 of the sliding tube 202 extends out of the first through hole 201. The head 203 of the sliding tube 202 The diameter of the sliding tube 202 is greater than the diameter of the first through hole 201, the head of the sliding tube 202 is in the shape of a disk, the sliding tube 202 is a hollow tube with two ends connected, and an airway 204 is arranged 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 the sliding tube 202 is in the first position when the head 203 of the sliding tube 202 is not subjected to external force. 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 to move toward the first through hole 201 for a predetermined distance, the airway 204 The air guide cavity 205 is connected to the lumen of the sliding tube 202. Therefore, when the rotating tube 2 moves along the head 203 of the sliding tube 202 installed on the stirring plate 200 to face the veterinary drug particles in the drying tank 100, if the veterinary drug particles on the side of the stirring plate 200 located at the head 203 of the sliding tube 202 are too wet and stick together, the resistance of the sticking veterinary drug particles to the head 203 of the rotating tube 2 is increased, forcing the head 203 of the sliding tube 202 to be pressed by the sticking veterinary drug particles to overcome the elastic cooperation force of the inner wall of the sliding tube 202 and the stirring plate 200 and move toward the first passage. The hole 201 moves a predetermined distance to reach the second position, so that the airway 204 connects the air guide cavity 205 with the tube cavity of the sliding tube 202, so that the hot air entering the air guide cavity 205 from the inside of the rotating tube 2 will reach the tube cavity of the sliding tube 202 through the airway 204, and will 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 bonded veterinary drug particles (and unbonded veterinary drug particles) near the sliding tube 202, thereby quickly drying and separating the bonded veterinary drug particles, and further improving the drying efficiency and drying effect of the veterinary drug particles.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] See also Figures 1 to 3 as well as Figures 6 to 10According to one embodiment of the present invention, the drying device further comprises a stirring and impacting mechanism 300 arranged on the outer side of the peripheral wall of the pipe section of the rotating tube 2 located inside the drying tank body 100, and a vibration plate 6 arranged on the inner wall surface of the drying tank body 100, the vibration plate 6 comprises a plurality of second through holes 61 formed thereon, the second through holes 61 penetrate the stirring plate 200 along 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 tube 2, the width direction of the vibration plate 6 is consistent with the axial direction of the rotating tube 2, the vibration plate 6 extends toward the rotating tube 2 along the radial direction of the rotating tube 2 and is spaced from the rotating tube 2, the stirring and impacting mechanism 300 The structure 300 includes a first working state and a second working state. In the first working state, the stirring and impacting mechanism 300 does not contact the vibration plate 6 when rotating with the rotating tube 2. In the second working state, the stirring and impacting mechanism 300 hits the vibration plate 6 when passing through the vibration plate 6 as the rotating tube 2 rotates. In this embodiment, the second working state can be triggered as needed, so that the stirring and impacting mechanism 300 hits the vibration plate 6 when passing through the vibration plate 6 as the rotating tube 2 rotates, thereby causing the vibration plate 6 to vibrate to drive the veterinary medicine particles near the vibration plate 6 to vibrate, thereby suddenly increasing the gap between the veterinary medicine particles and improving the hot air blowing and drying effect.

[0028] 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 impact piece. The support block 301 is connected to the support block 301 on the outer side of the peripheral wall of the rotating tube 2. A hollow portion 303 is formed in the middle of the support block 301. The hollow portion 303 is provided with slots at both ends of 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 impact piece includes an insert portion 305 and an impact portion 306. The insert portion 30 5 is inserted into the corresponding inserting cavity 307 in the support block 301 along the vertical direction, the inserting cavity 307 is connected with the second slot 317, the impact part 306 extends out of the support block 301, and the second end of the spring piece 302 is provided with a first wedge surface 308, the first wedge surface 308 is gradually inclined upward toward the rotating tube 2 along the radial direction of the rotating tube 2, and the side of the inserting portion 305 forms a second wedge surface 309, the second wedge surface 309 is in an oblique wedge fit with the first wedge surface 308, when the spring piece 302 is in an extended state, the inserting portion 305 is supported at a first height by the oblique wedge fit, so that the height of the impact part 306 is higher than the height of the upper end surface of the corresponding vibration 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 part 305 is dropped to the second height under the action of its own gravity through the wedge cooperation, so as to drive the impact part 306 to drop to a height lower than the upper end surface of the corresponding vibration plate 6. Preferably, there is a gap between the upper and lower ends of the spring piece 302 and the support block 301. This gap allows the veterinary drug particles to flow through, thereby increasing the stirring effect of the veterinary drug particles and thus increasing the drying effect. In this embodiment, the triggering principle of the second working state is: if the rotating tube 2 rotates so that the veterinary drug particles near the side of the spring piece 302 moving against the veterinary drug particles are too wet and cause adhesion When the phenomenon occurs, the resistance generated by the bonded veterinary drug particles to the spring piece 302 increases, causing the spring piece 302 to bend, so that the insert part 305 drops to the second height under the action of its own gravity through the wedge cooperation, so as to drive the impact part 306 to drop to a height lower than the upper end surface of the corresponding vibration plate 6. Spring pieces 302 with different elastic forces can be selected according to actual needs, and should be adapted to the resistance of the veterinary drug particles to the spring piece 302. For example, when the humidity of the veterinary drug particles is 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 (the veterinary drug particles are bonded to a certain level), it can push the spring piece 302 to bend.

[0029] According to a specific embodiment of the present application, the support block 301 forms a buffer airway 310, the first port of the buffer airway 310 is connected to the tube cavity of the rotating tube 2, and the second port of the buffer airway 310 leads to the insert cavity 307. When the insert portion 305 is at a first height, the insert portion 305 blocks the second port of the buffer airway 310. When the insert portion 305 is at a second height, the second port of the buffer airway 310 is connected to the insert cavity 307. In this embodiment, since the insert portion 305 is at the second height, the second working state is When triggered, the impact part 306 performs the impact operation, and at this time, the second port of the buffer air channel 310 is connected to the insert cavity 307, and the hot air in the buffer air channel 310 quickly surrounds the insert part 305 to relieve the rigid contact between the insert part 305 and the support block 301, thereby preventing the reaction force of the vibration plate on the vibration plate 6 from being excessively transmitted to the support block 301 when the impact part 306 hits the vibration plate 6, and then transmitted to the rotating tube 2, that is, the reaction force of the vibration plate 6 on the rotating tube 2 when it vibrates is relieved, thereby improving the rotation stability and service life of the rotating tube 2.

[0030] In this embodiment, specifically, two buffer air ducts 310 can be set, and the two buffer air ducts 310 are respectively located on the upper and lower sides of the hollow portion 303. Two rubber ring plugs 311 are mounted on the insert portion 305. The side surface of the rubber ring plug 311 forms a ring plug slope 318 that narrows upward, and the second port of the buffer air duct 310 forms a port slope that matches the slope of the rubber ring plug 311 (roughly along a rectangular ring, matching the rectangular cross-section of the insert portion 305). When the insert portion 305 is supported at a first height by an inclined wedge fit, the ring plug slope of the rubber ring plug 311 presses against the port slope of the second port of the buffer air duct 310 to seal and block the second port.

[0031] According to one embodiment of the present application, the upper end of the insert portion 305 is connected to an extension block 312 extending away from the rotating tube 2, and 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, and the lower end of the impact shaft is used to impact the upper end of the vibration plate 6 in the second working state.

The output shaft of the motor 7 is transmission-connected to the input shaft of the gearbox 8, and a bearing is provided at the through-fitting position of the rotating tube 2 and the upper cover 1.

[0036] According to one embodiment of the present application, the hot air generating source includes a hot air blower 14 installed on the upper cover 1, the first heat pipe 3 and the second heat pipe 4 are both connected to the output end of the hot air blower 14, and the drying device also includes a feed hopper 15 arranged on the upper cover 1 and a discharge pipe 16 arranged at the bottom of the drying tank body 100, the feed hopper 15 and the discharge pipe 16 respectively lead to the interior of the drying tank body 100 and the feed hopper 15 and the discharge pipe 16 can be provided with on-off valves. In this embodiment, the first heat pipe 3 and the second heat pipe 4 share the hot air of the same hot air blower 14, but as other embodiments, the first heat pipe 3 and the second heat pipe 4 can also be independently equipped with hot air blowers 14.

[0037] In addition, a plurality of support columns 17 can be connected to the bottom of the drying tank body 100. The bottom of the drying tank body 100 preferably forms a conical bottom plate 103 that gradually narrows downward. The discharge pipe 16 is connected below the tip of the conical bottom plate 103. The air outlet hole 102 can be connected to an air outlet pipe 18. The air outlet pipe 18 can pass through a drying box to discharge the gas. The drying box can dry the water vapor discharged from the drying tank body 100.

[0038] It should be noted that the above embodiments only express the preferred implementation of the present application, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the present application. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, such as combining different features in various embodiments, etc., which should all fall within the scope of protection of the present application.
