Technical Field

[0001] This utility model relates to the field of down dust filtration and separation, and in particular to a high-efficiency down dust filtration and separation device. Background Technology

[0002] During the down processing and production process, the down raw materials often contain a large amount of dust, down fragments and other impurities. If they are not effectively filtered and separated, it will not only affect the cleanliness and quality of the down products.

[0003] A search revealed a Chinese patent announcement (CN215800056U) that discloses a vertical down dust separation device, comprising a working box and a dispersing mechanism. The working box has sliding groove plates on its left and right walls, with a filter plate slidably connected between the two corresponding sliding groove plates. A down outlet is located in the middle of the lower surface of the working box, and a baffle is inserted into the inlet at the front end of the down outlet. A door is hinged to the front side of the working box, and an installation pipe is located at the air outlet in the middle of the upper surface of the working box, with an exhaust fan inside the installation pipe.

[0004] By pushing the handle to the right, the handle moves the push plate to the right via the sliding column. The push plate scrapes off the fine down and dust adhering to the filter plate. However, it only scrapes off the upper side of the filter plate, and the dust still falls through the holes in the filter plate, resulting in poor cleaning effect. Therefore, a high-efficiency down and dust filtration and separation device is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency down dust filtration and separation device, which aims to improve the problem of poor dust cleaning effect on the filter plate in the prior art.

[0009] Preferably, one end of the second spring is fixedly connected to the inner wall of the right side of the machine body, and the other end of the second spring is fixedly connected to the upper side of the locking block.

[0010] Preferably, the lower side of the card block is inclined, the outer wall of the card block is slidably connected to the right inner wall of the machine body, and the lower side of the card block is engaged with the upper inner wall of the sealing door.

[0011] Preferably, one end of the spring is fixedly connected to the lower inner wall of the fixing plate, and the other end of the spring is fixedly connected to the upper side of the scraper.

[0012] Preferably, the outer wall of the scraper is slidably connected to the lower inner wall of the fixed plate.

[0013] Preferably, the pusher plate two is arranged in an inverted trapezoidal shape, with the upper side of the pusher plate two being the long side, and the upper outer wall of the pusher plate two sliding on the lower side of the filter plate.

[0014] This utility model has the following beneficial effects: 1. In this utility model, when the inverted trapezoidal pusher plate 2 on the dust collection box slides with the dust collection box, its long side scrapes against the lower side of the filter plate, scraping off the dust attached to the surface of the filter plate in time, preventing the filter plate from clogging, maintaining the unobstructed filtration channel, and ensuring the continuous and stable operation of the device.

There is no need to disassemble the complex structure, simplifying the cleaning process. It can clean the dust on the upper and lower sides of the filter plate at the same time, improving the cleaning effect.

[0015] 2. In this utility model, the scraper supported by the spring in the anti-winding component continuously adheres to the outer wall of the dispersing rod, scraping off the tangled down in real time, avoiding problems such as "jamming and speed reduction" caused by down tangling in the dispersing rod, and improving the overall dust separation efficiency.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a high-efficiency down dust filtration and separation device, comprising a body 1, a dust exhaust pipe 4 fixedly connected to the upper side of the body 1, a fan installed inside the dust exhaust pipe 4 to draw air out of the body 1, the dust exhaust pipe 4 and the fan cooperate to form a dust removal airflow channel to achieve dust extraction and discharge, a rotating door 6 installed on the front side of the body 1 for taking and putting down, a rotating door assembly installed on the right inner wall of the body 1 to control the opening and closing of the right opening of the body 1, and the rotating door assembly for closing the right opening of the body 1, a pull-out block 5 slidably connected to the left inner wall of the body 1, and a fixed connection on the right side of the pull-out block 5. A dust collection box 9 is fixedly connected to the right side of the push plate 8 and the pull block 5. The dust collection box 9 serves as a dust collection carrier, accommodating the dust on the lower side of the filter plate 7. A push plate 12 is fixedly connected to the upper inner wall of the dust collection box 9. The push plate 12 is arranged in an inverted trapezoidal shape, with the upper side of the push plate 12 being the long side. The upper outer wall of the push plate 12 slides on the lower side of the filter plate 7. A dispersing rod 10 is provided on the inner wall of the machine body 1. The dispersing rod 10 is driven by a motor, which drives the dispersing rod 10 to rotate, dispersing the down and promoting dust separation. An anti-winding component is provided on the inner wall of the machine body 1 to prevent down from getting tangled at the end of the dispersing rod 10 away from the center.

[0020] Reference Figure 2 and Figure 4The anti-winding component includes a fixing plate 13, which provides a mounting support base for the scraper 11. The outer wall of the fixing plate 13 is fixedly connected to the inner wall of the machine body 1. The scraper 11 is elastically connected to the lower inner wall of the fixing plate 13 by a spring 14. The spring 14 gives the scraper 11 elastic extension and retraction characteristics to adapt to the movement of the dispersing rod 10. The outer wall of the scraper 11 is slidably connected to the lower inner wall of the fixing plate 13. One end of the spring 14 is fixedly connected to the lower inner wall of the fixing plate 13, and the other end of the spring 14 is fixedly connected to the upper side of the scraper 11.

[0021] Reference Figure 2 and Figure 5 The revolving door assembly includes a sealing door 2, which achieves the opening and closing operation of the opening through a rotating connection. The outer wall of the sealing door 2 is rotatably connected to the inner right wall of the body 1. A locking block 3 is elastically connected to the inner right wall of the body 1 through a spring 15. The spring 15 provides elastic locking force for the locking block 3. The lower side of the locking block 3 is inclined. The outer wall of the locking block 3 is slidably connected to the inner right wall of the body 1. The lower side of the locking block 3 is locked onto the inner upper wall of the sealing door 2. The locking structure between the locking block 3 and the sealing door 2 locks the sealing door 2 into a closed state. One end of the spring 15 is fixedly connected to the inner right wall of the body 1, and the other end of the spring 15 is fixedly connected to the upper side of the locking block 3. The connection method of the spring 15 provides elastic support for the locking block 3 and maintains the stability of the locking.

[0022] Working principle: During operation, the down feathers to be processed are first placed through the rotating door 6 on the front side of the machine body 1. The rotating door 6 is then closed to form a relatively enclosed space inside the machine body 1. At the same time, the sealing door 2 of the rotating door assembly, in cooperation with the locking block 3 and the spring 15, seals the opening on the right side of the machine body 1, further ensuring the airtightness of the machine body 1 and providing a stable environment for airflow circulation and dust separation.

[0023] After the device is started, the dispersing rod 10 rotates at high speed under the drive of the motor, dispersing the down inside the machine body 1 and fully exposing the dust trapped in the down. During this process, the anti-tangling component plays a role: the fixing plate 13 is fixed to the inner wall of the machine body 1, and the scraper 11 on its lower side adheres to the outer wall of the dispersing rod 10 under the elastic force of the spring 14. The scraper 11 scrapes off the tangled down, preventing the dispersing rod 10 from being affected by tangling and thus improving the dispersing effect.

[0024] At the same time, the fan in the dust exhaust pipe 4 starts, continuously drawing air out of the machine body 1 and forming a directional airflow within the machine body 1. The dust in the broken down feathers moves upward with the airflow, and when it passes through the filter plate 7, the down feathers and dust are separated. The gas containing smaller dust particles is discharged from the machine body 1 through the dust exhaust pipe 4.

[0025] As the dust collection box 9 and the second push plate 12 move, the scraped dust falls into the dust collection box 9. The dust collection box 9 is slidably connected to the inner wall of the body 1 via the pull block 5. The inverted trapezoidal push plate 12 on the upper side of the dust collection box 9 moves with the dust collection box 9, and its long side slides close to the lower side of the filter plate 7, scraping the dust attached to the lower surface of the filter plate 7 into the dust collection box 9 to prevent the filter plate 7 from clogging. As the pull block 5 moves, the push plate 8 pushes the dust on the upper side of the filter plate 7 to the right side of the body 1. By opening the sealing door 2, the dust is pushed out of the body 1, completing the cleaning and improving the cleaning efficiency.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
