A transmission rod 7 is rotatably connected through the interior of the filter plate 5. A brush 8 is fixedly connected to the outer wall of the transmission rod 7, and the brush 8 is located above the filter net 6. A sealing cover 11 is slidably connected to the top of the oil filter housing 1. A servo motor 13 is fixedly connected to the top of the sealing cover 11. A pressurizing mechanism is arranged on the top of the sealing cover 11, and the pressurizing mechanism is located on one side of the servo motor 13.

[0025] When using a multi-stage oil filter to filter the oil to be filtered, by putting the oil to be filtered into the interior of the multi-stage oil filter, the oil to be filtered can be filtered by the filter plate 5 and the filter net 6. When filtering the oil to be filtered again, the servo motor 13 drives the transmission rod 7 to rotate. When the transmission rod 7 rotates, it can drive the brush 8 to rotate above the filter net 6. The upper part of the filter net 6 can be cleaned through the brush 8 to prevent the sundries in the oil from blocking the filter net 6, so as to ensure that the filter net 6 can effectively filter the oil. The top of the oil filter housing 1 can be covered by the sealing cover 11, and the interior of the oil filter housing 1 can be pressurized through the pressurizing mechanism.

[0026] In a preferred embodiment, the pressurizing mechanism includes an installation box 15. The installation box 15 is fixedly connected to the top of the sealing cover 11. A pressurizing pump 16 is fixedly connected to the interior of the installation box 15, and the exhaust end of the pressurizing pump 16 penetrates into the interior of the oil filter housing 1.

[0027] The installation box 15 can provide an installation position for the pressurizing pump 16. The interior of the oil filter housing 1 can be pressurized through the pressurizing pump 16, so that the oil to be filtered in the interior of the oil filter housing 1 can quickly pass through the filter net 6, and thus the oil filter housing 1 can efficiently filter the oil.

[0028] In a preferred embodiment, a discharge pipe 2 penetrates and is installed on the outer wall of one side of the oil filter housing 1. A feed pipe 17 penetrates and is installed on the top of the sealing cover 11. Valves 18 are arranged on the outer walls of both the discharge pipe 2 and the feed pipe 17.

[0029] The oil to be filtered can be conveyed into the interior of the oil filter housing 1 through the feed pipe 17. The filtered oil can be discharged through the discharge pipe 2. The valves 18 enable the staff to feed and discharge materials.

[0030] Please refer to Figures 2 to 4 , a multi-stage oil filter:

[0031] The inner side wall of the oil filter housing 1 is provided with a limiting groove 3, and the support frame 4 is slidably connected to the inside of the limiting groove 3. The inner side wall of the oil filter housing 1 is fixedly connected with a support plate, and the support plate is located below the support frame 4.

[0032] By sliding the support frame 4 inside the limiting groove 3 and then supporting the support frame 4 through the support plate, the stability of the support frame 4 is ensured, and it is convenient for the staff to take out the support frame 4 from the inside of the oil filter housing 1, facilitating the subsequent cleaning of the filter net 6 by the staff.

[0033] In a preferred embodiment, the top end of the transmission rod 7 is fixedly connected with a connecting rod 9. A connecting groove 10 is formed at the top of the connecting rod 9. The output end of the servo motor 13 is fixedly connected with a rotating rod 14, and the bottom end of the rotating rod 14 is fitted and connected to the inside of the connecting groove 10.

[0034] By fitting and connecting the bottom end of the rotating rod 14 to the inside of the connecting groove 10, when the servo motor 13 operates, the transmission rod 7 can be driven to rotate through the rotating rod 14 and the connecting rod 9, and it is convenient for the staff to disassemble the transmission rod 7 from the servo motor 13, facilitating the subsequent maintenance by the staff.

[0035] In a preferred embodiment, a fixing bolt 12 is threadedly penetrated and installed on one outer wall of the sealing cover 11, and the bottom end of the fixing bolt 12 abuts against the top outer wall of the oil filter housing 1.

[0036] After the sealing cover 11 is slidably connected to the oil filter housing 1, by rotating the fixing bolt 12, the bottom end of the fixing bolt 12 abuts against the top outer wall of the oil filter housing 1, thereby ensuring the stability of the connection between the sealing cover 11 and the oil filter housing 1, and it is convenient for the staff to disassemble the sealing cover 11.

[0037] Working principle: When using the multi-stage oil filter to filter the oil to be filtered, the oil to be filtered can be conveyed into the inside of the oil filter housing 1 through the feed pipe 17. The filtered oil can be discharged through the discharge pipe 2. The oil to be filtered can be filtered through the filter plate 5 and the filter net 6. When filtering the oil to be filtered, the servo motor 13 drives the transmission rod 7 to rotate. When the transmission rod 7 rotates, it can drive the brush 8 to rotate above the filter net 6. The upper part of the filter net 6 can be cleaned through the brush 8 to prevent the sundries in the oil from blocking the filter net 6, thereby ensuring that the filter net 6 can effectively filter the oil. Then, the inside of the oil filter housing 1 can be pressurized through the booster pump 16, so that the oil to be filtered inside the oil filter housing 1 can quickly pass through the filter net 6, enabling the oil filter housing 1 to efficiently filter the oil.
