[0027] Working principle: During use, waste oil enters the oil residue filter 3 through the waste oil inlet 2, flows into the filter screen 26 through the port 27, and filters the residue in the waste oil through the filter screen 26. At the same time, the drive motor 21 converts electrical energy into mechanical energy to drive the anti-clogging stirring rod 20 to rotate, stirring the waste oil in the filter screen 26 to prevent the filter holes from clogging. The filtered waste oil is then evenly distributed in each filter cartridge 24, and the coking matter in the waste oil is initially filtered through the filter cartridge 24. It is then transported to the secondary waste oil filter tank 13 through the connecting pipe 9 for secondary filtration. The filtered heat transfer oil is discharged into the heat transfer oil heater through the clean oil outlet 15. If the filter cartridge 24 needs to be replaced, the connecting bracket 18 is removed, and the first internal hexagonal fixing bolt 5 is removed. The first sealing cover 4 is opened parallel to one end, and the positioning guide rod 6 supports and positions the opened position of the first sealing cover 4, so that the filter cartridge 24 is suspended in mid-air.
