[0025] like Figs. 1 to 3 As shown, a crude oil purification device is disclosed, including an oil inlet pipe 1. The oil outlet of the oil inlet pipe 1 is fixedly connected to a housing 6. Two filter components that penetrate into the housing 6 are symmetrically and sealed to the top of the housing 6. Both filter components include a frame 14, and the frame 14 is sealed to the housing 6. Rubber gaskets are fixedly connected to the outer walls on both sides of the frame 14 to ensure the sealing between the frame 14 and the housing 6. A filter screen 12 is fixedly connected to the inner surface of the frame 14. A mounting plate 2 is fixedly connected to the top of the frame 14 and is fixedly connected to the housing 6. The mounting plate 2 is fixedly connected to the housing 6 by bolts, which facilitates the installation and removal of the mounting plate 2.

[0026] Two outer shells 3 are symmetrically fixedly connected to the top of the housing 6. The two outer shells 3 are jointly equipped with a pushing assembly. The two movable ends of the pushing assembly are fixedly connected to the blocking pistons 13. When the corresponding frame 14 is pulled out, its surface rubber pad is always in contact with the outer wall of the blocking piston 13, which can carry the filtered impurities out of the housing 6. The pushing assembly includes an electric push rod 4, which is fixedly installed on the top of the housing 6. The driving end of the electric push rod 4 is fixedly connected to a U-shaped rod 5, and both ends of the U-shaped rod 5 are set through the adjacent outer shell 3. Both ends of the U-shaped rod 5 are fixedly connected to a movable plate 15, and the movable plate 15 is fixedly connected to the adjacent blocking piston 13. The U-shaped rod 5 is sealed and slidably connected to the two outer shells 3. The outer surface of the U-shaped rod 5 is symmetrically sealed with two rubber sleeves, which are fixedly connected to the adjacent outer shell 3 to ensure the sealing between the U-shaped rod 5 and the outer shell 3. The two blocking pistons 13 are sealed and fitted to the inner wall of the housing 6. The housing 6 and the blocking pistons 13 cooperate to divide the interior of the housing 6 into two independent chambers.

[0027] Two oil drain pipes 8 are symmetrically fixedly connected to the bottom of the housing 6. The two oil drain pipes 8 are fixedly connected to a pumping assembly. An oil outlet pipe 7 is fixedly connected to the oil outlet of the housing 6, and the oil outlet pipe 7 is interconnected with the pumping assembly. The pumping assembly includes an electric three-way valve 10.

[0029] When the filter screen 12 on this side needs to be replaced, the electric push rod 4 is activated. The electric push rod 4 pushes the two movable plates 15 to move simultaneously through the U-shaped rod 5. The movable plates 15 drive the blocking piston 13 to move until the blocking piston 13 abuts against the frame 14 connected to the filter screen 12 on this side, blocking the filter screen 12 that was just clear. At this time, the filter screen 12 on the side that was just blocked is now clear, and the crude oil is filtered through the filter screen 12.

The oil pump 9 operates, and the oil pump 9 uses the electric three-way valve 10 to transport the oil from the oil drain pipe 8 and the fixed pipe 11 to the oil outlet pipe 7 for discharge.

[0031] It should be noted that, in actual use, an existing controller can be added. The controller is electrically connected to the electric push rod 4, oil pump 9, and electric three-way valve 10 to facilitate overall control.
