The output of the brush 12 The end contacts the side wall of the filter drum 2. In this embodiment, when in use, first add pulp through the feed port 3, and then the pulp falls into the filter drum 2, then start the driving device to make the filter drum 2 start to rotate, adjust the speed of the driving device to adapt to the characteristics of the pulp, and then start the first motor 6. The output end of the first motor 6 drives the rotating shaft 7 to rotate, and the blade 8 on the rotating shaft 7 starts to rotate. The blade 8 is used to cut large pieces of material in the pulp to prevent them from clogging the filter drum 2 and improving the filtration efficiency. The cross bar 9 and the scraper 10 move with the rotation of the rotating shaft 7. The scraper 10 is used to scrape The material on the inner wall of the filter drum 2 is prevented from adhering to the side wall of the filter drum 2 and causing blockage, and the cross bar 9 also stirs the pulp during the rotation process, ensuring that large pieces of material can be cut under the action of the blade 8.

[0025] In actual use, it is further convenient to drive the filter cartridge 2 to rotate. In this embodiment, the driving device includes a second motor 13, an active bevel gear 14, a driven bevel gear 15, a driving shaft 16 and a rotating seat 17. The second motor 13 is installed at one end of the bottom wall of the shell 1 away from the discharge pipe 4, and the output end of the second motor 13 is installed with the active bevel gear 14. One end of the active bevel gear 14 is meshed and connected with the driven bevel gear 15, and a driving shaft 16 is installed in the driven bevel gear 15. The driving shaft 16 passes through the bottom wall of the shell 1 and is installed with the rotating seat 17. The top wall of the rotating seat 17 is fixedly connected to the bottom wall of the filter cartridge 2. When the second motor 13 starts When the filter is started, the motor starts to rotate and output power. The active bevel gear 14 starts to rotate and transmits the power to the driven bevel gear 15. A drive shaft 16 is installed in the driven bevel gear 15. When the driven bevel gear 15 rotates, the drive shaft 16 rotates accordingly. The drive shaft 16 drives the rotating seat 17 connected to it to rotate. The rotation of the rotating seat 17 drives the filter cartridge 2 to rotate together.
