When the equipment is working / in use: first, when the equipment is running, the dense honeycomb holes 11 in the arc filter plate 10 can be used to block dust and rags without affecting the ventilation effect, thereby preventing dust and rags from entering the oil pan body 12. If the arc filter plate 10 needs to be disassembled, replaced or refueled, the limit pin 8 can be held and pulled hard, thereby driving the strong tension spring 9 to elastically deform. When the limit pin 8 slides out of the slider 7 and the groove plate 6, the arc filter plate 10 can be moved out. If it is necessary to filter the oil in the oil pan body 12, the limit sleeve 15 can be threadedly engaged with the limit screw 14 by rotating it, so that the limit sleeve 15 can be moved out of the limit hook 13, so that the oil pan body 12 can be easily rotated and rotated to a certain angle. The rotation notch on the left side of the oil pan body 12 is directional, so that after rotating a certain angle, the oil pan mounting frame 5 will be squeezed, thereby eliminating the need for manual support. , automatically stops at a suitable angle, and the oil will flow to the connection between the oil pan body 12 and the oil extraction pipe 18. The oil will be pumped by the oil pump 19 and flow into the double filter cartridge 17 and be filtered for the first time by the filter block 22. The filtered oil may carry a small part of impurities and enter the filter box 27 through the oil outlet pipe 20 for centralized collection. The filter box 27 has a V-shaped filter plate 25 that can be pulled out by the arc handle 26 to facilitate secondary filtration and extraction and cleaning of impurities.
