[0036] 1. In this utility model, by tightening bolt one and pulling the fixing plate and fixing rod, the scraper can easily slide on the filter plate, scrape off the accumulated particles and discharge them through the through holes. This not only ensures the continuous and efficient filtration capacity of the filter plate, but also greatly simplifies the cleaning process and improves the overall efficiency of oil pollution treatment. At the same time, timely cleaning of particles on the filter plate also avoids the problems of clogging and reduced filtration efficiency, ensuring the smooth progress of subsequent oil pollution treatment work.

[0037] 2. In this utility model, the rotation of the cleaning plate is achieved by the transmission of the first and second bevel gears driven by the motor, which immediately scrapes off the oil floating on the surface of the sewage in the treatment bucket. The horizontal tilt setting and rotational coordination of the cleaning plate enable the oil to be effectively scraped into the collection ring. Through the tilt design of the collection ring, the oil flows smoothly into the collection pipe and is finally collected in the collection bucket. This not only improves the timeliness of oil treatment, but also avoids the long-term residence and diffusion of oil in sewage. Attached Figure Description

[0059] Example 3:

[0060] Based on Example 2, in order to further improve the sewage treatment efficiency, a collection component is provided on the treatment tank 1;

[0061] As a preferred implementation, a collection component is used to centrally collect oil stains;

[0062] In a preferred embodiment, the collection component includes: a collection ring 501, which is fixedly arranged around one side of the middle of the processing tank 1 for collecting oil; an oil drain trough 502, which is provided on the processing tank 1 corresponding to the collection ring 501 for discharging oil into the collection ring 501; and a collection pipe 503, which is fixedly arranged at the bottom end of the collection ring 501 for discharging the collected oil into the collection tank.

[0063] It should be noted that the collection ring 501 is set at an angle, and the collection tube 503 is located at the lowest point of the collection ring 501.

[0064] In a preferred embodiment, the oil drain trough 502 extends through the treatment tank 1.

[0065] Working principle: In use, firstly, wastewater is introduced into the treatment tank 1 through the inlet pipe on the tank cover 2. As the wastewater enters the treatment tank 1, larger particles mixed in with the wastewater are filtered through the filter plate 303. The wastewater is ready when it is level with the lower surface of the oil drain tank 502. When it is necessary to remove the larger particles filtered on the filter plate 303, firstly, loosen the two sets of bolts 301. Bolts 301 are threaded onto the treatment tank 1 and move to one side. When bolts 301 are removed from the treatment tank 1, they are pulled to one side to fix them. Plate 307, fixed plate 307 drives fixed rod 306 to move, fixed rod 306 drives scraper 305 to slide on slide groove 302, so that scraper 305 scrapes and cleans larger particles on filter plate 303 and discharges them through through hole 304. This makes it easy for users to remove larger particles accumulated on filter plate 303 in a timely manner, ensuring the efficiency of subsequent filtration of larger particles in sewage. The operation is simple. Then, motor 401 is turned on. Motor 401 drives shaft 402 to move between treatment tank 1 and protective cover. Rotating on 405, the first shaft 402 drives the first bevel gear 403 to rotate, the first bevel gear 403 drives the second bevel gear 404 to rotate, and the second bevel gear 404 drives the second shaft 407 to rotate on the support frame 406. The second shaft 407 drives two sets of cleaning plates 408 to scrape off the oil floating on the surface of the sewage in the treatment tank 1. By adjusting the horizontal tilt of the cleaning plates 408 and coordinating with their rotation, the oil is scraped into the collection ring 501 for collection. The tilt of the collection ring 501... Oil sludge flows onto the collection pipe 503 and is then collected in the collection bucket. This allows for the immediate removal of oil sludge from the wastewater surface, preventing prolonged retention and spread of oil in the wastewater and improving the timeliness of oil sludge treatment. Simultaneously, the collection ring 501 ensures that the removed oil sludge is quickly collected for subsequent processing and disposal, reducing secondary pollution of the environment. After the oil sludge treatment is completed, valve 6 is opened to discharge the wastewater from the treatment bucket 1.
