During the process of adding cleaning liquid to the cleaning tank 1 through the water injection pipe 10, the oil stains floating on the surface of the water source inside the cleaning tank 1 enter the drain box 11 through the through-hole 29. Then, the oil stains are recycled through the oil drain pipe 30. Thus, while replenishing the cleaning liquid, the oil stains generated during cleaning can be automatically discharged into the cleaning tank 1, greatly improving practicality and ensuring the quality of the cleaning liquid.

[0031] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, the telescopic cylinder 6 is activated, causing the movable end of the telescopic cylinder 6 to drive the lifting plate 7 to descend. The filter screen body 9, which is mounted on the bottom positioning plate 8 of the lifting plate 7, enters the U-shaped frame 12 through the feed inlet 18, which can drive the filter screen body 9 into the space between the cleaning rollers 15. The servo motor 14 is activated, and the output shaft of the servo motor 14 drives the cleaning roller 15 on one side to rotate, causing the gear 17 at the rear end of the cleaning roller 15 to mesh and drive the gear 17 at the rear end of the cleaning roller 15 on one side. The filter screen body 9 is repeatedly immersed in the cleaning tank 1 for soaking and contact with the rotating cleaning rollers 15, which allows the oil stains on the surface of the filter screen body 9 to be soaked in the cleaning tank 1. Then, the oil stains on the surface of the filter screen body 9 are cleaned by the cleaning rollers 15. The soaking and cleaning operations are repeated, which can greatly improve the cleaning effect of the filter screen body 9. During the process of extending into and out of the feed inlet 18, the water inlet pipe 20 is connected to the outside. A booster pump delivers clean water into the water supply pipe 21.

The top side of the filter screen body 9 is magnetically attracted and fixed to the electromagnets 28 on the inner walls of the fixed block 25 and the movable block 26, which can more quickly attract and fix the filter screen body 9. After cleaning, first turn off the electromagnets 28 on the fixed block 25, then pull the filter screen body 9 forward from the positioning plate 8, and finally turn off the electromagnets 28 on the movable block 26 to remove the filter screen body 9 from the positioning plate 8. After cleaning a large number of filter screen bodies 9, the oil stains are denser than water, causing the oil stains to float on the surface of the cleaning liquid. During the process of adding cleaning liquid to the cleaning tank 1 through the water injection pipe 10, the oil stains floating on the surface of the water source inside the cleaning tank 1 enter the drain box 11 through the outlet 29, and then the oil stains are recycled through the oil drain pipe 30.
