Slide grooves are provided on both sides of the filter cartridge 5, and a slider 6 is slidably connected to the inner side of the slide groove. The top of the slider 6 is connected to the top of the inner wall of the slide groove through a connecting spring 7. When the filter cartridge 5 is able to vibrate, the slider 6 can be supported by the connecting spring 7. A rotating shaft 8 is fixedly connected to the surface of the slider 6, and one end of the two rotating shafts 8 is respectively connected to a sliding block 9 and a nut seat 10, the sliding block 9 is sleeved on the outer side of the slide rod 3, and the nut seat 10 is threadedly connected to the outer side of the screw rod 4.

[0030] There are two tooth plates 11 that allow the gear 12 to rotate. Both sides of the surface of the tooth plate 11 are fixedly connected to the inner wall of the working box 1 through fixing rods. The top of the tooth plate 11 is meshedly connected with the gear 12 sleeved on the outside of the rotating shaft 8. When the filter cartridge 5 moves from the right side to the left side, the filter cartridge 5 just rotates 180 degrees and the gear 12 rotates half a circle.

[0031] The filter cartridge 5 can be vibrated to clean the filter cartridge 5. The cleaning mechanism includes a mounting box 13 and an abutment block 15. The abutment block 15 is a semicircular block, and the bottom end of the abutment block 15 is centrally symmetrically arranged with the bottom end of the filter cartridge 5. The feed pipe 2 is located directly above the coating box, and the abutment block 15 is located directly above the slag receiving box. An eccentric wheel 14 is rotatably connected to the inside of the mounting box 13.

When the residual impurities need to be cleaned, the servo motor drives the screw rod 4 to rotate, and the screw rod 4 drives the filter cartridge 5 to move through the nut seat 10. During the movement, the gear 12 flips the filter cartridge 5 through the tooth plate 11, so that the bottom end of the filter cartridge 5 abuts against the bottom of the abutment block 15. As the drive motor drives, the eccentric wheel 14 drives the abutment block 15 to vibrate the filter cartridge 5 through the support rod 16, so that the impurities can be completely poured out of the filter cartridge 5.
