Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically to a built-in large-capacity pill dryer. Background Technology

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials, used for drying objects. A dryer heats materials to vaporize and remove moisture (generally water or other volatile liquid components) to obtain solid materials with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. It is widely used in the processing of food, traditional Chinese medicine and other fields. However, the existing drum-type pill dryer has the following defects: 1. The drying hot air blows from the outside of the drum inward. The drying hot air must first pass through the mesh drum. Since the drum is mesh, some of the drying hot air is blocked by the drum wall and cannot enter the drum to do work, resulting in a waste of drying hot air resources; 2. A large number of pills are piled up at the bottom of the drum. The gaps between the pills are small, especially when the diameter of the pills is piled up. This makes it difficult for the drying hot air to pass through the pill pile. The internal temperature of the pill pile is not easily carried away, resulting in high-temperature evaporation of the pills, which causes the pills to turn blackish-brown or dark black, affecting the quality of the finished pills; 3. Due to the low utilization rate of drying hot air and the difficulty in carrying away the internal heat of the pill pile, the existing pill dryer cannot process a large number of pills at one time, which affects the drying efficiency of the pills and cannot meet the needs of large-scale industrial production.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN220355929U discloses a built-in large-capacity pill dryer, comprising a drying chamber with an inlet and an outlet at both ends, a rotatable drum inside the drying chamber (the drum being mesh-like), and a hot air circulation system. The hot air circulation system includes an air inlet and an air outlet to circulate and deliver hot air to the inside of the drying chamber for pill drying, and a hot air pipe is provided inside the drum.

[0004] Although the above-mentioned existing technical solution allows the hot air nozzle to spray and dry the pills with hot air at close range and vertically, thus improving the drying efficiency of the pills, it uses the opening and closing of the second solenoid valve to supplement fresh air through the air inlet. After it is opened, external impurities can easily be carried into the device by the airflow, which can easily contaminate the pills and interfere with the operation of the hot air circulation system.

The structure is simple and easy to operate. It can intercept and scrape away impurities carried in during makeup air, and the easy disassembly and maintenance further ensure the drying effect.

[0024] The specific details of the hot air circulation system 2 mentioned above have been described in detail in the prior art document CN220355929U, a built-in large-capacity pill dryer, so they will not be repeated in this solution.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the snap-fit ​​assembly includes a first fixing plate installed at one end of the top of the placement frame 7. A first spring is installed on one side of the first fixing plate, and a second fixing plate 14 is installed on the other end of the first spring. A placement seat 15 is installed at one end of the second fixing plate 14. A placement groove that is slidably connected to the placement seat 15 is opened at one end of the top of the fixing seat 6. First, in use, the recycling groove on the placement frame 7 can be attached to the outer wall of the air supply tube 4 near the lower part of the extension rod 9. Then, slide it down to allow the placement seat 15 to initially slide into the inner side of the placement groove. At the same time, the snap-fit ​​plate 11 and the first rubber pad also partially slide into the inner side of the groove. Then, press the placement seat 15 down to make the second rubber pad retract.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a slide rod 16 is slidably connected inside the placement seat 15. An extrusion groove is formed inside the placement seat 15 on the outside of the slide rod 16. An extrusion plate 17 is slidably connected inside the extrusion groove. A second spring is installed between one end of the extrusion plate 17 and the inner wall of the extrusion groove. An operation groove is formed inside the placement seat 15 below the extrusion groove. An installation plate 18 is installed at one end of the inner wall of the operation groove. An installation rod is rotatably connected to one side of the installation plate 18. A movable plate 19 is fixedly sleeved on the outside of the installation rod. A torsion spring 20 is installed between the installation rod and the inner wall of the installation plate 18. A sliding groove is formed on one side of the outer wall of the placement seat 15. The movable plate 19 and the sliding groove are slidably connected. Next, a second rubber pad is embedded in the inner wall of the placement groove. The cross-section of the placement groove is L-shaped. A pull ring is installed at one end of the slide rod 16 extending to the top of the placement seat 15. Then, when the outer end of the movable plate 19 contacts the narrow end of the inner wall of the placement groove, it is squeezed and drives the torsion spring 20 and the mounting rod to rotate. It retracts to the inner side of the operating groove. The first rubber pad on the clamping plate 11 also retracts against the inner side of the groove until the sliding groove is aligned with the protruding end of the placement groove. The movable plate 19 can be driven to pop out. At this time, after releasing the hand, the second rubber pad and the first rubber pad rebound. One end of the movable plate 19 abuts against the inner wall of the placement groove, completing the assembly of the placement frame 7 and the sweeping plate 5.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the sweeping recovery assembly includes a connecting rod installed at the other end of the inner wall of the air supply duct 4. A fan blade 8 is installed at one end of the connecting rod, and an extension rod 9 is installed at the axis of the fan blade 8. A groove is provided on one side of the extension rod 9. A connecting plate is installed at one end of the inner wall of the placement frame 7. A movable disk 10 is rotatably connected inside the connecting plate. A retaining plate 11 is installed on one side of the movable disk 10, and the retaining plate 11 is slidably connected to the groove. A recovery groove is provided at the bottom inner side of the placement frame 7. A first rubber pad is installed on the side of the retaining plate 11 near the groove. A sweeping plate 5 is installed on the other side of the retaining plate 11. A brush 12 is installed on one side, and a dustproof net 13 is installed between the outer wall of the extension rod 9 and the inner wall of the air supply tube 4. Furthermore, when the solenoid valve is opened, the airflow from the outside is drawn into the inside of the drying chamber body 1 by the suction force of the circulating airflow of the hot air circulation system 2. The dustproof net 13 can intercept the impurities carried by the airflow. At the same time, when the airflow blows over the fan blade 8, it can drive it to rotate. In conjunction with the card plate 11 and the groove, it can continue to drive the sweeping plate 5 and the movable disc 10 to rotate, so that the brush 12 brushes the surface of the dustproof net 13 and scrapes the impurities off, causing them to fall into the inside of the recycling tank for collection.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a lower pressure plate 21 is installed on the side of the outer wall of the slide rod 16 located inside the operating groove. An annular groove is formed on the outer wall of the lower pressure plate 21. A top block 22 is slidably connected to the inner side of the annular groove. The top block 22 and the lower pressure plate 21 are slidably connected. A third spring is installed between the top block 22 and the lower pressure plate 21. A push groove is formed on one side of the movable plate 19. The top block 22 and the push groove are slidably connected. Furthermore, when it is necessary to maintain the brush 12 or clean the impurities inside the recycling tank, the placement seat 15 can be pressed again to squeeze the second rubber pad, while the second fixed plate... 14 will also compress the first spring to retract, allowing the movable plate 19 to move slightly away from the inner wall of the placement groove. Then, the pull ring can be fastened to press down the slide bar 16, causing the top block 22 to contact the push groove on the movable plate 19. After being pressed, the push groove can drive the movable plate 19 to deflect and cause the torsion spring 20 to retract. During the push, the top block 22 can slide inside the annular groove according to the change of distance, compressing the third spring to retract and achieve the avoidance operation. After the movable plate 19 is retracted into the inner side of the operation groove, the placement frame 7 and the placement seat 15 can be lifted upward and separated to achieve the cleaning and maintenance operation.

[0029] The implementation principle of a built-in large-capacity pill dryer according to an embodiment of this application is as follows: During use, the recovery trough on the placement frame 7 can be attached to the outer wall of the air supply duct 4 near the lower part of the extension rod 9. Then, slide it downwards to allow the placement seat 15 to initially slide into the inner side of the placement trough. Simultaneously, the clamping plate 11 and the first rubber pad also partially slide into the groove. Next, press down on the placement seat 15 to retract the second rubber pad. When the outer end of the movable plate 19 contacts the narrow inner wall of the placement trough, it is squeezed, driving the torsion spring 20 and the mounting plate... The lever rotates and retracts to the inside of the operating slot. The first rubber pad on the clamping plate 11 also retracts against the inside of the groove until the sliding slot is aligned with the protruding end of the placement slot. Then, the movable plate 19 can be ejected. When the hand is released, the second and first rubber pads rebound, and one end of the movable plate 19 abuts against the inner wall of the placement slot, completing the assembly of the placement frame 7 and the sweeping plate 5. When the solenoid valve is opened, the airflow is affected by the suction of the circulating airflow of the hot air circulation system 2, and the external airflow is drawn into the inside of the drying chamber body 1. The dust screen 1 3 can intercept impurities carried by the airflow. Simultaneously, the airflow blowing over the fan blades 8 causes them to rotate. This, combined with the clamping plate 11 and the groove, further rotates the sweeping plate 5 and the movable disc 10, causing the brush 12 to sweep the surface of the dustproof net 13, scraping off impurities and causing them to fall into the collection trough for centralized collection. When maintenance of the brush 12 or cleaning of impurities inside the collection trough is required, the placement seat 15 can be pressed again to squeeze the second rubber pad. Simultaneously, the second fixing plate 14 will also squeeze the first spring to retract. After moving the movable plate 19 slightly away from the inner wall of the placement groove, the pull ring can be fastened and the slide bar 16 can be pressed down, so that the top block 22 contacts the push groove on the movable plate 19. After being pressed, the push groove can drive the movable plate 19 to deflect and cause the torsion spring 20 to retract. During the push, the top block 22 can slide inside the annular groove according to the change of distance, and squeeze the third spring to retract and achieve the avoidance operation. After the movable plate 19 is retracted into the inner side of the operation groove, the placement frame 7 and the placement seat 15 can be lifted upward and separated to achieve the cleaning and maintenance operation.

[0030] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
