[0030] A transmission assembly is provided between the scraper 5 and the tank body 1. The transmission assembly is connected to the pusher 7 to drive the pusher 7 to slide radially along the rotating shaft 4.

[0031] The transmission assembly includes a threaded rod 8, which is radially arranged along the shaft 4 and rotatably connected to the scraper 5.

[0032] A linkage is provided between the threaded rod 8 and the inner wall of the tank 1. The linkage is in transmission cooperation with the threaded rod 8 to drive the threaded rod 8 to rotate.

[0033] The linkage includes gear 9, first arc-shaped rack 10, and second arc-shaped rack 11. Gear 9 is coaxially and fixedly connected to threaded rod 8.

[0034] The first arc-shaped rack 10 and the second arc-shaped rack 11 are both fixed circumferentially to the inner wall of the tank body 1 along the shaft 4. The center of the arc of the first arc-shaped rack 10 and the second arc-shaped rack 11 is located on the central axis of the tank body 1.

[0036] A collection box 13 for collecting particulate mechanical impurities on the filter screen 12 is fixedly installed on the tank body 1. The collection box 13 is connected to the filter chamber. The connection between the collection box 13 and the tank body 1 is located below the near ends of the first arc-shaped rack 10 and the second arc-shaped rack 11, and the bottom inner wall of the connection between the collection box 13 and the tank body 1 is flush with the top plane of the filter screen 12.

[0037] Working principle: When using this equipment, industrial oil is added into the filter chamber through the oil injection pipe 2. After being filtered by the filter screen 12, the industrial oil in the filter chamber enters the oil storage chamber of the adsorption cylinder 15 through the oil inlet pipe 14. At this time, the electrostatic adsorption rod 16 uses high voltage electrostatics to draw particulate matter and oxidized organic acids, alkaline nitrogen, bound water and other fluid polar substances in the industrial oil through the diaphragm cylinder 17 and collect them into the adsorption space, and finally flow out from the drain pipe 19. The finished oil with the pollutants removed flows out from the oil outlet pipe 18.

[0038] After the filter screen 12 has been used for a period of time, start the motor 3. The output shaft of the motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the scraper 5 to rotate. The scraper 5 drives the brush 6 to clean the particulate mechanical impurities on the filter screen 12, and at the same time gathers the particulate mechanical impurities to the front side of the brush 6 along the rotation path.

[0039] When scraper 5 rotates, it drives threaded rod 8 and push plate 7 to revolve around shaft 4, and threaded rod 8 drives gear 9 to revolve around shaft 4.

[0040] As gear 9 revolves around shaft 4, it gradually approaches and eventually engages with the first arc-shaped rack 10. As gear 9 continues to revolve around shaft 4, the first arc-shaped rack 10 drives gear 9 to rotate. Gear 9 drives threaded rod 8 to rotate, and threaded rod 8 pushes push plate 7 to slide radially away from shaft 4. During this process, push plate 7 pushes particulate mechanical impurities accumulated on brush 6 along its rotation path to the edge of filter screen 12.

[0041] When gear 9 revolves to the position above the connection between collection box 13 and tank 1, pusher plate 7 pushes particulate mechanical impurities into collection box 13. Pusher plate 7 stops sliding after gear 9 disengages from first arc-shaped rack 10.

[0042] Then, gear 9 revolves until it contacts the second arc-shaped rack 11, which pushes gear 9 to flip. Gear 9 drives threaded rod 8 to reverse, and threaded rod 8 pushes push plate 7 to slide radially along shaft 4 and approach shaft 4 to slide and reset.

[0043] During this process, the V-shaped combined surface on the push plate 7 pushes away particulate mechanical impurities to prevent them from getting stuck between the rotating shaft 4 and the push plate 7 after the push plate 7 is reset.

[0044] As the shaft 4 continues to rotate, the pusher plate 7 intermittently pushes particulate mechanical impurities into the collection box 13.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
