The second telescopic rod 11 has a cavity inside. The first telescopic rod 10 extends into the cavity of the second telescopic rod 11 and slides with the second telescopic rod 11. A spring 12 is fixed between the bottom surface of the first telescopic rod 10 and the bottom surface of the inner wall of the second telescopic rod 11.

[0029] When the gear 3 closest to the opening rotates, it drives the adjacent gear 3, and so on. All the gears 3 drive the first telescopic rod 10 and the second telescopic rod 11 to rotate. The second telescopic rod 11 drives the center block 5 to rotate. The rotation of the center block 5 drives all the blades 13 and brush blocks 14 to rotate. The brush blocks 14 loosen the higher oil sludge. After the higher oil sludge is loosened, it becomes shorter. The blades 13 are brought downward by the spring 12. The blades 13 crush the oil sludge, making it easier for the scraper block 9 to scrape it off. The spring 12 can adjust the position of the blades 13 and brush blocks 14 according to the height of the oil sludge.

The motor 7 drives the lead screw 8 to rotate. The adjusting block 6 drives the scraper 9 to move. The movement of the scraper 9 drives the gear 3 near the opening to rotate at the edge of the rack 2. The blade 13 and the brush bristle block 14 move forward while rotating, cleaning the entire filter plate 19. The scraper 9 scrapes off the broken sludge. Small pieces of sludge can fall directly through the filter screen, while larger pieces continue to be driven by the scraper 9. When the gear 3 near the opening rotates, it drives the adjacent gear 3, and so on. Some gears 3 drive the first telescopic rod 10 and the second telescopic rod 11 to rotate. The second telescopic rod 11 drives the center block 5 to rotate. The rotation of the center block 5 drives all the blades 13 and brush blocks 14 to rotate. The brush blocks 14 loosen the higher oil sludge. After the higher oil sludge is loosened, it becomes shorter. The blades 13 are pulled downward by the spring 12. The blades 13 crush the oil sludge, making it easier for the scraper 9 to scrape it off. The spring 12 can adjust the position of the blades 13 and brush blocks 14 according to the height of the oil sludge. When the bristles of the brush block 14 are worn, the bolt 17 is rotated to turn the bolt 17 out of the threaded hole. The locking block 16 is removed from the locking groove 15, and the brush block 14 is separated from the blades 13. The brush block 14 can be replaced, which makes brushing oil sludge more efficient.
