Inside the filter cartridge 5; the feed channel 7 is used to feed the filter tank 1, and the discharge channel 8 is arranged at the bottom of the filter tank 1. The discharge channel 8 is used to discharge the filtered lubricating oil. In the process of filtering the lubricating oil, the lubricating oil enters the filter cartridge 5 from the feed channel 7, and the annular rotating seat 2, the mounting plate 4 and the filter cartridge 5 are driven to rotate by starting the driving component 3. The rotating filter cartridge 5 improves the filtering efficiency of the lubricating oil. By opening the sealing connection component 6, the filter cartridge 5 is separated from the mounting plate 4, which facilitates the replacement and cleaning of the filter cartridge 5 after long-term filtering work.

[0028] Specifically, the drive assembly 3 includes a drive motor 3-1 arranged on the filter tank 1, the drive end of the drive motor 3-1 extends into the filter tank 1 and is provided with a gear 3-2, and the annular rotating seat 2 is provided with an annular outer gear ring 3-3 that is meshed with the gear 3-2. During use, the gear 3-2 is driven to rotate by starting the drive motor 3-1, and the rotating gear 3-2 drives the annular outer gear ring 3-3, the annular rotating seat 2, the mounting plate 4 and the filter cartridge 5 to rotate, thereby realizing the filtration of the lubricating oil by driving the filter cartridge 5 to rotate through the drive assembly 3.

[0029] Specifically, the sealing connection component 6 includes an annular mounting groove 6-1 provided at the bottom of the mounting plate 4, the annular mounting groove 6-1 is used to install the filter cartridge 5, an annular sealing gasket 6-2 is provided at the notch of the annular mounting groove 6-1, and two annular sealing gaskets 6-2 are provided, corresponding to the inner and outer side walls of the filter cartridge 5 respectively, and the sealing between the mounting plate 4 and the filter cartridge 5 is achieved by providing the annular sealing gaskets 6-2, a plurality of through holes 6-3 are provided between the bottom of the annular mounting groove 6-1 and the upper surface of the mounting plate 4, and a plurality of through holes 6-3 are provided on the filter cartridge 5. There are bolts 6-4 arranged corresponding to several through holes 6-3. The top of the bolt 6-4 passes through the through hole 6-3 and is provided with a limit nut 6-5. When the filter cartridge 5 needs to be replaced, the limit nut 6-5 is unscrewed and the filter cartridge 5 is pulled outward to disengage the filter cartridge 5 from the annular mounting groove 6-1, thereby realizing the disassembly of the filter cartridge 5. The replaced filter cartridge 5 is inserted into the annular mounting groove 6-1 and the bolt 6-4 is passed through the through hole 6-3.
