The discharge port of the fixed box 15 is fixedly connected to the connecting pipe 18. The outside of the connecting pipe 18 is sleeved with a connecting ring 27. The bottom of the connecting ring 27 is fixedly connected to a filter cylinder 23. A plurality of groups of scrapers 28 for scraping the inner wall of the filter cylinder 23 are installed at the bottom of the connecting pipe 18. The outside of the connecting ring 27 is sleeved with a fixed ring 22;

[0028] The fixed ring 22 is fixedly connected to the connecting pipe 18 through the support frame 19. A limiting component for limiting the connecting ring 27 is arranged on the transmission cylinder 11. A rotating component for driving the connecting ring 27 to rotate is arranged on the fixed box 15.

[0029] A feeding component for feeding powder is arranged on the transmission cylinder 11. First, the feeding component feeds the powder into the fixed box 15. The powder enters the connecting pipe 18 through the discharge port in the fixed box 15. The rotating component drives the connecting ring 27 to rotate. The connecting ring 27 drives the filter cylinder 23 to rotate. During the rotation process, the scraper 28 scrapes the inner wall of the filter cylinder 23 to scrape off the powder blocked on the filter cylinder 23, which can reduce the dust generation phenomenon when the powder is poured. When the filter cylinder 23 needs to be cleaned, first remove the limiting component with external tools. The connecting ring 27 loses the limiting support and drops, which is convenient for cleaning the filter cylinder 23. When installation is required, first insert the connecting ring 27 between the scraper 28 and the limiting plate 24, and the limiting component supports and fixes the connecting ring 27.

[0030] The rotating component includes a toothed ring 21 and a gear 20. The toothed ring 21 is fixedly connected to the connecting ring 27. The toothed ring 21 meshes with the gear 20. A second motor 17 for driving the gear 20 to rotate is installed on one side of the fixed box 15. By setting the rotating component, the connecting ring 27 can be driven to rotate, thereby driving the filter cylinder 23 to rotate, and the scraper 28 scrapes the dust on the filter cylinder 23 to reduce blockage by dust.

[0031] The limiting component includes a limiting groove 29 and a limiting block 25. The limiting groove 29 is formed on the connecting ring 27. No less than four groups of limiting blocks 25 are slidably connected in the limiting groove 29. The limiting blocks 25 are fixedly connected to the top of the fixed ring 22 through bolts, which can limit the rotation of the connecting ring 27 and is convenient for removing the connecting ring 27 for cleaning.

[0032] The feeding component includes a screw conveyor blade and a first motor 12. The screw conveyor blade is rotatably connected in the transmission cylinder 11. The first motor 12 for driving the screw conveyor blade is installed on the top of the transmission cylinder 11. The feeding hopper 13 is installed at the feeding port of the transmission cylinder 11. The bottom of the transmission cylinder 11 is fixedly connected to the base 14. The discharge port of the transmission cylinder 11 is communicated with the fixed box 15. Pour the powder to be fed into the feeding hopper 13, and the first motor 12 starts to work, driving the screw conveyor blade in the transmission cylinder 11 to rotate to feed the powder. The powder enters the connecting pipe 18 through the discharge port in the fixed box 15, which is convenient for feeding.

[0033] A plurality of groups of limiting plates 24 are fixedly installed at the bottom of the fixed ring 22. A fixed block is fixedly connected to the bottom of the limiting plate 24. A telescopic cover 16 is rotatably connected to the fixed block. An anti-slip pad is installed at the bottom of the telescopic cover 16. By providing the anti-slip pad, the shaking of the telescopic cover 16 can be reduced when it contacts the feeding port of the next device.

[0034] A positioning ring 26 is fixedly connected to the bottom of the filter cartridge 23. The top of the positioning ring 26 is slidably connected to the bottom of the limiting plate 24. By providing the positioning ring 26, the filter cartridge 23 can be limited when it moves upward.

[0035] The working principle of the present utility model is as follows: During use, first cover the telescopic cover 16 on the feeding port of the next device, pour the powder to be fed into the feeding hopper 13. The first motor 12 starts to work, driving the auger conveying blade in the transmission cylinder 11 to rotate to feed the powder. The powder enters the connecting pipe 18 through the discharge port in the fixed box 15. The second motor 17 starts to work, driving the gear 20 to rotate. The gear 20 drives the connecting ring 27 to rotate through the meshing with the toothed ring 21. The connecting ring 27 drives the filter cartridge 23 to rotate. During the rotation process, the scraper 28 scrapes the inner wall of the filter cartridge 23 to scrape off the powder blocked on the filter cartridge 23, which can reduce the dust generation phenomenon when the powder is poured. When the filter cartridge 23 needs to be cleaned, first remove the bolts with external tools, take out the limiting block 25, and disengage from the limiting groove 29. The connecting ring 27 loses the support of the limiting block 25 and slides down between the scraper 28 and the limiting plate 24, facilitating the cleaning of the filter cartridge 23. When installation is required, first insert the connecting ring 27 between the scraper 28 and the limiting plate 24, and make the toothed ring 21 and the gear 20 mesh. Insert the limiting block 25 into the limiting groove 29 to support the connecting ring 27, and use external tools to fix the bolts, so as to position and fix the limiting block 25 and complete the installation of the connecting ring 27.
