A centrifugal oil purifier pre-filter device comprises a filter barrel 1, the circumferential surface of the filter barrel 1 is fixedly connected with an oil inlet 2, the upper end of the filter barrel 1 is provided with an end cover 3, the upper end circumferential surface of the filter barrel 1 is provided with a fixing assembly 5, the filter barrel 1 is connected to the end cover 3 through the fixing assembly 5, and the upper end of the end cover 3 is fixedly connected with an oil outlet 4; the interior of the filter barrel 1 is fixedly connected with a support ring 13, the interior of the support ring 13 is slidably connected with a filter core 7, and the circumferential surface of the filter core 7 is slidably connected with a cleaning ring 8; the lower end of the support ring 13 is provided with a power mechanism, and the power mechanism is used to drive the cleaning ring 8 to move.

[0024] Specifically, the oil to be filtered and purified is added into the filter barrel 1 through the oil inlet 2, and the oil is preliminarily filtered under the action of the filter element 7. The oil filtered by the filter element 7 enters the centrifugal oil purifier through the oil outlet 4, and the centrifugal oil purifier further filters the oil; when the filter element 7 needs to be cleaned, the power mechanism works to drive the cleaning and scraping ring 8 to move outside the filter element 7. As the cleaning and scraping ring 8 moves, the impurities on the filter element 7 are cleaned, thereby improving the filtering efficiency of the filter element 7; when the filter element 7 needs to be replaced, the fixing assembly 5 is disassembled, and the end cover 3 can be removed, so that the filter element 7 can be taken out from the inside of the filter barrel 1 to realize the replacement of the filter element 7.

[0025] The fixing assembly 5 includes a first fixing ear 501, a second fixing ear 502, a nut 503 and a threaded rod 504. The circumferential surface of the filter barrel 1 is fixedly connected with the first fixing ear 501, the upper end of the first fixing ear 501 is fixedly connected with the threaded rod 504, the circumferential surface of the threaded rod 504 is slidably connected with the second fixing ear 502, the second fixing ear 502 is fixedly connected to the end cover 3, and the circumferential surface of the threaded rod 504 is threadedly connected with the nut 503. When the end cover 3 needs to be disassembled, the nut 503 is first removed from the threaded rod 504, so as to facilitate the disassembly of the end cover 3. When fixing the end cover 3, the second fixing ear 502 on the end cover 3 is aligned with the threaded rod 504, so as to facilitate the end cover 3 to be covered on the filter barrel 1. After the end cover 3 is installed, the nut 503 is tightened to achieve the fixation of the end cover 3.

[0026] The power mechanism includes a bearing seat 9, a screw rod 10, a slider 11 and a motor 12. The inner wall of the filter barrel 1 is fixedly connected to the bearing seat 9, the inner part of the bearing seat 9 is rotatably connected to the screw rod 10, the circumferential surface of the screw rod 10 is threadedly connected to the slider 11, and the slider 11 is fixedly connected to the scraper ring 8; the lower end of the support ring 13 is fixedly connected to the motor 12, and the output end of the motor 12 is fixedly connected to the screw rod 10. When working, the motor 12 is started, and the output end of the motor 12 drives the screw rod 10 to rotate, and then drives the scraper ring 8 to slide on the filter element 7 with the cooperation of the slider 11, thereby facilitating the cleaning of the filter element 7.

The positioning column 15 is fixedly connected to the support ring 13. By setting the positioning hole 14 and the positioning column 15, the filter core 7 can be limited during operation with the cooperation of the positioning hole 14 and the positioning column 15, thereby preventing the filter core 7 from being offset.

[0029] The lower end of the filter barrel 1 is fixedly connected with a sewage outlet 19, and the circumferential surface of the sewage outlet 19 is threadedly connected with a sealing cover 6.
