The oil drain port 5011 is arranged on the wall of the second filter tank 102.

[0037] An oil cleaning mechanism 5 is provided in the second filter tank 102. When in use, the floating oil layer that covers the conical groove 509 will flow into the conical groove 509 and be discharged through the connecting hose 5010. When the oil layer needs to be cleaned manually, the pressing rod 505 is pressed downward to press the conical groove 509 into the oil layer. Due to the height difference, the floating oil will flow into the conical groove 509 and be discharged through the connecting hose 5010, thereby facilitating manual cleaning of the floating oil.

[0038] The working principle and use process of the utility model are as follows: during specific use, the driving mechanism 2 drives the rotating rod 305 threadedly connected to it through the threaded connecting column 307 to rotate, and the rotation of the rotating rod 305 drives the two scrapers 306 to rotate in the barrel body 301, and the rotation of the two scrapers 306 stirs the kitchen waste oil and water discharged into the barrel body 301 through the water inlet 104, thereby improving the filtration efficiency and preventing the filter holes from being blocked by residues or grease. The filtered oil and water flow to the second filter pool 102 and the third filter pool 103 through the outlet 4, and the oil and water are separated by physically utilizing the different densities of oil and water. After filtration, when it is necessary to clean the residue filtered in the residue filter barrel 3, the rotating rod 305 is driven to rotate by rotating the hand lever 308, so that the threaded connecting column 307 is screwed out of the transmission shaft 203, and at the same time, it is upward. By lifting the residue filter barrel 3, the residue filter barrel 3 can be disassembled and taken out as a whole, so that the residue in the residue filter barrel 3 can be poured out conveniently. The residue and grease remaining on the inner wall of the barrel body 301 can be rotated by the hand lever 308 to rotate the rotating rod 305, and the rotation of the rotating rod 305 drives the scraper 306 to rotate at the same time. Through the rotation of the scraper 306, the residue and grease remaining on the inside of the barrel body 301 are scraped off, which is convenient for cleaning. When it is necessary to clean the grease separated in the upper layer of the second filter tank 102, the pressing rod 505 is repeatedly pressed downward to make the upper end of the conical groove 509 immersed in the oil layer, so that the grease flows into the conical groove 509 and is discharged to the oil discharge port 5011 through the connecting hose 5010, and then discharged through the oil discharge port 5011, thereby realizing the cleaning of the upper floating oil, and the slider 502 can be moved on the slide rail 501 to achieve a better cleaning effect.
