[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model transports the oil-water mixture into the primary separation chamber through the liquid inlet pipe. When the liquid in the primary separation chamber gradually increases, the liquid is blocked by the inclined plate, so that the liquid is filtered by the first filter screen and the second filter screen. Since the oil and water entering the primary separation chamber are separated up and down, and because the first filter screen is hydrophilic and oleophobic, the liquid water enters the water storage tank through the first filter screen, and the oil in the liquid enters the secondary separation chamber through the second filter screen, thereby realizing the first separation of oil and water. When the liquid water enters the water storage tank, the control valve can be used to control the water. Open and close to control the discharge of liquid from the first drain pipe. When liquid oil enters the secondary separation chamber, the amount of liquid oil gradually increases. At the same time, the liquid oil is discharged from the third filter screen to the oil storage tank. At this time, the oil extraction assembly can extract it. A small amount of liquid that enters the secondary separation chamber is limited by the trapezoidal plate, which causes it to gather on the lower side of the trapezoidal plate and is discharged through the second drain pipe. This allows the equipment to form a separation cycle during separation, which can quickly and efficiently process a large amount of oil-water mixture, while ensuring the efficiency of oil-water separation and further preventing the oil-water mixture from clogging the sewer.

[0015] 2. After the equipment has been working for a certain period of time, impurities in the mixed liquid may adhere to the first filter and the second filter, causing blockage. At this time, the pull rod can be pulled to move. When the pull rod is pulled, the second spring is stretched, and the slide plate moves in the slide groove, while the scraper is subjected to the elastic force of the first spring, so that it fits on the first filter. As the scraper moves up and down, it can be effectively cleaned to ensure its permeability. At the same time, as the slide plate moves, the rack can simultaneously drive the gear to rotate, and then the brush can rotate. At this time, the brush can clean the second filter at the same time, thereby further improving the permeability of the material, reducing the blockage of the equipment, and further ensuring the efficiency and quality of its oil-water separation.

[0032] Working principle:

[0033] During operation, the oil-water mixture is transported from the liquid inlet pipe 3 to the primary separation chamber 2. When the liquid in the primary separation chamber 2 gradually increases, the liquid is blocked by the inclined plate 4, so that the liquid is filtered by the first filter screen 6 and the second filter screen 13. Since the oil and water entering the primary separation chamber 2 are separated from each other, and because the first filter screen 6 is hydrophilic but super oleophobic underwater, the liquid water enters the water storage tank 7 through the first filter screen 6, and the oil in the liquid enters the secondary separation chamber 10 through the second filter screen 13. , thereby realizing the first separation of oil and water, and when liquid water enters the water storage tank 7, it can be controlled by opening and closing the control valve 9 to control the liquid water to be discharged from the first drain pipe 8, and when the liquid oil enters the secondary separation chamber 10, the liquid oil gradually increases, and at the same time, the liquid oil is discharged from the third filter screen 15 to the oil storage tank 16, at this time, the oil pumping assembly 17 can pump it out, and the small amount of liquid water entering the secondary separation chamber 10 is limited by the trapezoidal plate 14, so that it is gathered on the lower side of the trapezoidal plate 14, thereby The oil and water mixture is discharged through the second drain pipe 11, and then the equipment forms a separation cycle during separation, which can quickly and efficiently process a large amount of oil-water mixture, while ensuring the efficiency of oil-water separation, and further preventing the oil-water mixture from clogging the sewer. After the equipment has worked for a certain period of time, impurities in the mixed liquid may adhere to the first filter screen 6 and the second filter screen 13, thereby clogging them. At this time, the pull rod 28 can be pulled to move. When the pull rod 28 is pulled, the second spring 29 is stretched, and the slide plate 20 moves in the slide groove 19, while the scraper 22 is subjected to the elastic force of the first spring 21, so that it fits on the first filter screen 6.

At this time, the brush 27 can simultaneously clean the second filter screen 13, thereby further improving the permeability of the material, reducing the clogging of the equipment, and further ensuring the efficiency and quality of its oil-water separation.
