[0025] The oil filtering device for reducing oil loss adopts the above structure. When it is necessary to filter the oil, pour the oil into the filter cartridge 3, start the first motor 4 to drive the filter cartridge 3 to rotate, and use centrifugal force to filter the oil. After filtering the oil, use the lifting assembly 10 to move the carrier 7 along the height direction of the operating table 1. At this time, the connecting rod 9 will drive the first disc 11 and the second disc 12 to move up and down inside the filter cartridge 3. At this time, start the blower 8 to transport the gas into the air cavity 13, and the gas will be ejected toward the outside along the circumference of the first disc 11 to spray the oil in the filter holes on the filter cartridge 3 into the filter barrel 2.

[0026] In this embodiment, the lifting assembly 10 includes a screw rod 14 and a guide rod 15. The screw rod 14 is arranged at the first end of the operating platform 1. A second motor 5 is installed at the bottom of the operating platform 1. The bottom of the screw rod 14 passes through the operating platform 1 and is coaxially fixed with the output end of the second motor 5. The guide rod 15 is fixed to the second end of the operating platform 1. A threaded block 16 is fixed to the first end of the bearing platform 7. The threaded block 16 is threadedly connected to the screw rod 14. A guide block 17 is fixed to the second end of the bearing platform 7. The guide block 17 movably passes through the guide rod 15. After filtering the oil, the second motor 5 is started to drive the screw rod 14 to rotate. The screw rod 14 will drive the threaded block 16 to move up or down when rotating forward or reverse.

[0027] Alternatively, the lifting assembly 10 can also be set to other suitable structures or forms, such as directly installing a hydraulic cylinder on the operating platform 1, installing the bottom of the supporting platform 7 to the output end of the hydraulic cylinder, and starting the hydraulic cylinder to drive the supporting platform 7 to move along the height direction of the operating platform 1.

[0028] In this embodiment, a bottom shaft 18 is fixed to the bottom of the filter cartridge 3, and a bearing seat 19 is fixed to the bottom of the filter barrel 2. The bottom shaft 18 and the inner ring of the bearing seat 19 are coaxially fixed; when filtering oil by centrifugal force, the bearing seat 19 increases the rotational stability of the filter cartridge 3.

[0029] In this embodiment, a fixing rod 20 is fixed at the bottom of the supporting platform 7, and a scraper 21 with an annular structure is installed at the bottom of the fixing rod 20.

After filtering the oil, the lifting assembly 10 is used to move the supporting platform 7 along the height direction of the operating table 1. At this time, the fixing rod 20 will drive the scraper 21 to move up and down. The scraper 21 is used to scrape the inner wall of the filter barrel and the outer wall of the filter cartridge 3 to prevent the oil from adhering to the inner wall of the filter barrel and the outer wall of the filter cartridge 3, thereby reducing the loss of oil after being filtered.

[0030] In this embodiment, the outer ring and the inner ring of the scraper 21 are both made of rubber material; when the scraper 21 scrapes the inner wall of the filter barrel 2 and the outer wall of the filter cartridge 3, the scraper 21 made of rubber material will increase the friction of the scraper 21 on the filter barrel 2 and the filter cartridge 3, and reduce the gap between the scraper 21 and the filter barrel 2 and the filter cartridge 3, so as to prevent the oil attached to the filter barrel 2 and the filter cartridge 3 from passing through the gap between the scraper 21 and the filter barrel 2 and the filter cartridge 3 and still attaching to the filter barrel 2 and the filter cartridge 3.

When filtering the oil by centrifugal force, the bearing seat 19 will increase the rotation stability of the filter cartridge 3. After filtering the oil, start the second motor 5 to drive the screw rod 14 to rotate. The screw rod 14 will drive the threaded block 16 to move up or down when rotating forward or reverse. At this time, the threaded block 16 will drive the bearing platform 7 to move up or down. At this time, the connecting rod 9 will drive the first disc 11 and the second disc 12 to move up and down inside the filter cartridge 3. At this time, start the blower 8 to transport the gas into the air cavity 13. When the user starts the blower 8, the air outlet of the blower 8 will transport the gas to the water in the liquid storage barrel 22. The water will filter a large amount of impurities in the gas. After being filtered, the gas will pass through the filter The tube 24 transports gas into the air cavity 13 to reduce impurities or particles attached to the gas, and then the gas will be ejected toward the outside along the circumference of the first disc 11 to spray the oil in the filter holes on the filter cartridge 3 into the filter barrel 2. At the same time, the fixing rod 20 will drive the scraper 21 to move up and down, and the scraper 21 will scrape the inner wall of the filter barrel and the outer wall of the filter cartridge 3 to prevent the oil from adhering to the inner wall of the filter barrel and the outer wall of the filter cartridge 3, thereby reducing the loss of the oil after being filtered. When the scraper 21 scrapes the inner wall of the filter barrel 2 and the outer wall of the filter cartridge 3, the scraper 21 made of rubber will increase the friction of the scraper 21 on the filter barrel 2 and the filter cartridge 3, and reduce the gap between the scraper 21 and the filter barrel 2 and the filter cartridge 3, so as to prevent the oil attached to the filter barrel 2 and the filter cartridge 3 from passing through the gap between the scraper 21 and the filter barrel 2 and the filter cartridge 3 and still adhering to the filter barrel 2 and the filter cartridge 3.
