[0031] By adopting the above technical solution, the first motor 5 is used to drive the auger mesh 18 to rotate, and the auger mesh 18 rotates to discharge the solid residue in the sewage through the discharge pipe 10 into the residue collection bucket 9.

[0032] Working principle: When the utility model is in use, firstly, sewage is passed through the water inlet pipe 2 into the residue conveying device 4, and the first motor 5 is used to drive the auger mesh 18 to rotate. The auger mesh 18 rotates to discharge the solid residue in the sewage through the discharge pipe 10 into the residue collection bucket 9, and the filtered sewage passes through the filter 19 into the oil drainage pool 1, and the highest water level of the sewage in the oil drainage pool 1 is higher than the oil scraper 7 and is level with the oil suction end of the oil suction pipe 12. Since the density of oil is higher than that of water, the oil in the sewage will float on the surface of the sewage, and the first baffle 6 can control the water flow speed so that the sewage The oil has enough time to float to the surface of the sewage. When the sewage in the oil drain pool 1 reaches the highest water level, the first valve 3 on the water inlet pipe 2 is closed, and then the second motor 13 is used to drive the screw rod 8 to rotate. The rotation of the screw rod 8 drives the scraper plate 7 to slide and scrape the oil on the surface of the sewage and concentrate it on one side of the oil drain pool 1. Then, the oil suction pipe 12 is used to suck out the oil and discharge it into the waste oil collection barrel 11. Then, the second valve 15 on the drain pipe 14 is opened to discharge the sewage in the oil drain pool 1 through the drain pipe 14. The second baffle 16 can prevent the sewage on the side of the first baffle 6 from being discharged without removing the oil.
