Description

Technical Field

[0001] This utility model relates to the technical field of air filtration and purification devices, and more specifically, it relates to an air filtration and purification device for goat milk powder production. Background Technology

[0002] Goat milk powder is a powder made by dehydrating and drying fresh goat milk, and it is rich in nutrients. Compared with cow milk powder, it contains higher levels of protein, fat, vitamins, and minerals, and is more easily digested and absorbed by the human body. Therefore, goat milk powder is an ideal choice for many people, especially those who are allergic to cow milk protein or lactose intolerant.

[0003] Goat milk powder production places strict requirements on the cleanliness of the workshop air, and air filtration and purification devices are key equipment to achieve this goal. The current mainstream solution utilizes a combination of pre-filters and high-efficiency filters for high-efficiency filtration. However, existing purification devices of this type have revealed some problems in practical applications: 1. After prolonged operation, a large amount of dust, hair, and other impurities accumulate on the surface and inside the filter media of a pre-filter. These impurities clog the filter pores, significantly increasing airflow resistance, leading to a reduction in airflow and a sharp decline in filtration efficiency. To maintain the purification effect of the device, the pre-filter must be replaced frequently, increasing costs.

[0004] 2. Replacing the pre-filter requires interrupting the operation of the entire air purification system. Furthermore, the existing structural design does not consider quick disassembly and assembly, making the replacement process often time-consuming and labor-intensive. This results in prolonged downtime, preventing air treatment and directly reducing the system's overall effective purification efficiency and operating time, leading to economic losses.

[0005] 3. The existing equipment lacks the function of online cleaning of the pre-filter. Faced with accumulated impurities on the filter media, the only solution is manual replacement or removal for cleaning. This high frequency of physical maintenance significantly increases the labor intensity and time cost for workers, reducing the equipment's usability.

[0006] Therefore, there is an urgent need to develop an air filtration and purification device for goat milk powder production. Utility Model Content

[0023] Please see Figures 1-6 An air filtration and purification device for goat milk powder production includes a support leg 1, a fixed shell 2 fixedly connected to the support leg 1, a sliding frame 3 fixedly connected to the fixed shell 2, high-efficiency filters 4 evenly distributed inside the sliding frame 3, an exhaust port 5 provided on the fixed shell 2, an exhaust fan fixedly connected to the exhaust port 5, an air inlet 6 provided on the fixed shell 2, a rotating sleeve 7 rotatably connected to the fixed shell 2, a rotating disk 8 rotatably connected to the rotating sleeve 7, a controller 9 fixedly connected to the rotating disk 8, and connecting pipes 10 evenly distributed circumferentially on the rotating sleeve 7. A fixed sleeve 11 is fixedly connected and connected to the connecting pipe 10, and a filter structure is provided inside the connecting pipe 10. A cleaning structure is provided on the rotating disk 8. A gear ring 12 is fixedly connected to the rotating sleeve 7. A motor 13 is fixedly connected to the fixed shell 2. A gear 14 is fixedly connected to the output end of the motor 13, and the gear 14 meshes with the gear ring 12. The fixed shell 2 is provided with a through hole. Two guide plates 15 are fixedly connected to the fixed shell 2. A sealing plate 16 is slidably connected between the two guide plates 15. The sealing plate 16 is slidably connected to the fixed shell 2. An electric push rod 17 is fixedly connected to the fixed shell 2. The telescopic end of the electric push rod 17 is fixedly connected to the sealing plate 16.

[0024] Please see Figure 6 The filter structure includes a fixed ring 18, which is fixedly connected to the connecting pipe 10. The fixed ring 18 is slidably connected to two sliding rods 19. The sliding rods 19 are fixedly connected to a fixing member 20. A primary filter 21 is installed between the two sliding rods 19. The sliding rods 19 are threadedly connected to a nut 22. A connecting ring 23 is fixedly connected between the two sliding rods 19. A spring 24 is sleeved on the sliding rods 19. The two ends of the spring 24 are fixedly connected to the fixed ring 18 and the connecting ring 23, respectively.

[0025] Specifically, in this embodiment, the exhaust fan at the exhaust port 5 (not shown in the figure) is started. After the exhaust fan is started, air enters from the air inlet 6. The air passes through the primary filter 21 and flows along the connecting pipe 10 on the front side. The air then passes through the three-layer high-efficiency filter 4 and is then discharged from the exhaust port 5. The air is filtered and purified by the primary filter 21 and the three-layer high-efficiency filter 4.

[0026] The controller 9 sets the start time of the motor 13. When the set time is reached, the controller 9 starts the motor 13. The output shaft of the motor 13 drives the gear 14 on it to rotate. The gear 14 drives the gear ring 12 to rotate. The gear ring 12 drives the rotating sleeve 7 to rotate 60°, thereby connecting the new primary filter 21 with the air inlet 6. This prevents excessive impurities from accumulating on the primary filter 21, which would reduce the filtration efficiency of the primary filter 21 and obstruct airflow.

[0027] When the pre-filter 21 needs to be replaced, the electric push rod 17 is activated by the controller 9. The electric push rod 17 moves the sealing plate 16 to the left, releasing the seal on the through hole of the fixed shell 2. By loosening the two nuts 22, the pre-filter 21 can be removed from the connecting pipe 10. Then, a new pre-filter 21 is replaced. Turning the nuts 22 again fixes the pre-filter 21 between the two sliding rods 19, thereby improving the convenience of replacing the pre-filter 21 without affecting the normal filtration and purification of the air.

[0028] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The cleaning mechanism includes two drain pipes 25, which are fixedly connected to and connected to the lower side of the fixed shell 2. A connecting column 26 is fixedly connected to the rotating disk 8. A connecting plate 27 is fixedly connected between the connecting column 26 and the support leg 1. An arc-shaped shell 28 is fixedly connected to the connecting column 26. A flange pipe 29 is fixedly connected to and connected to the arc-shaped shell 28. The flange pipe 29 passes through the rotating disk 8. Two through holes are provided on the lower side of the arc-shaped shell 28. The lower side of the arc-shaped shell 28 slides and seals against the inner wall of the fixed sleeve.

[0029] Specifically, in this embodiment, before using the device, the flange pipe 29 is connected to the air outlet pipe of the air pump, and the drain pipe 25 is connected to the collection box. When the primary filter 21 moves to the lower side of the fixed shell 2 with the rotating sleeve 7, the two connecting pipes 10 are simultaneously connected to the two drain pipes 25 and the two through holes on the lower side of the arc-shaped shell 28. The air pump is started, and the air pump inputs high-speed flowing air into the flange pipe 29. The high-speed flowing air impacts the primary filter 21, backflushing and cleaning the impurities on the upper side of the primary filter 21, reducing the residual amount of impurities on the primary filter 21. The cleaned impurities enter through the drain pipe 25. When the high-speed airflow impacts the primary filter 21, the primary filter 21 causes two sliding rings to move along the fixed ring 18. The two sliding rods 19 cause the connecting ring 23 to compress the two springs 24. When the air stops impacting the primary filter 21, the sliding rods 19 and the primary filter 21 return to their original positions under the elastic force of the springs 24. The vibration generated when the primary filter 21 returns to its original position further cleans the impurities remaining on it. By controlling the air output frequency of the air pump, the primary filter 21 moves back and forth in the connecting pipe 10, further improving the cleaning effect on the impurities on the primary filter 21.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
