[0049] The positioning member A2 comprises a positioning ring A21, a connecting ring A22 is fixed at the bottom of the positioning ring A21, the inner ring of the positioning ring A21 has the same diameter as the inner ring of the connecting ring A22, a positioning ring B23 is fixed at the inner ring of the connecting ring A22, the bottom of the positioning ring B23 is on the same horizontal plane as the bottom of the connecting ring A22, the inner ring diameter of the positioning ring B23 is smaller than the inner ring diameter of the connecting ring A22, and a bearing 3 is provided at the top of the positioning ring B23;

[0050] The connecting ring B41 is rotatably connected to the connecting ring A22 through the bearing 3. Specifically, the bearing 3 includes an outer shaft ring and an inner shaft ring. A plurality of balls are arranged between the inner ring wall of the outer shaft ring and the outer ring wall of the inner shaft ring, so that the outer shaft ring and the inner shaft ring can rotate relative to each other through the plurality of balls. The outer shaft ring of the bearing 3 is connected to the inner ring of the connecting ring A22.

[0051] A connecting ring B41 is sleeved on the outer wall of the oil-gas separation filter element 4 near the bottom, and the connecting ring B41 is connected to the inner ring wall of the inner shaft ring, so that the oil-gas separation filter element 4 can rotate in the positioning member A2 through the bearing 3.

[0052] The shaft 52 is also provided with a positioning frame 51, a dispersion wheel 55, and a stirring wheel 56. The dispersion wheel 55 is located below the transmission pressure wheel 53, and the stirring wheel 56 is located below the dispersion wheel 55. The positioning frame 51 is overlapped on the positioning member A2, and is used to position the shaft 52, so that the shaft 52 is more stable when rotating, and when the shaft 52 rotates, it can drive the dispersion wheel 55 and the stirring wheel 56 to rotate in the dispersion tank 1;

[0053] The dispersion wheel 55 includes a collar C, and the collar C is sleeved on the shaft 52 and locked by bolts. The outer ring of the collar C is connected to a plurality of striking rods, which are arranged in a circle around the outer ring of the collar C.

[0056] During operation, the position where the inlet pipe A11 is connected to the separation tank 1 is tilted from top to bottom 3 facing the force plate 82 in the transmission member 8, the control valve on the inlet pipe B12 is closed, and the control valve on the inlet pipe A11 is opened. When the oil-gas mixture enters the separation tank 1 from the inlet pipe A11, it impacts the lower half of the force plate 82, and continuously impacts multiple force plates 82, so that the transmission member 8 rotates and drives the oil-gas separation filter element 4 to rotate in the positioning member A2 through the bearing 3. The rotation of the oil-gas separation filter element 4 can throw away a part of the oil contaminated on the surface through centrifugal force, so that the gas passing effect of the oil-gas separation filter element 4 is not affected. In addition, during the rotation of the transmission member 8 and the oil-gas separation filter element 4, the thrown-off oil will be thrown onto the inner wall of the separation tank 1, and the force plate 82 can clean and scrape off the oil on the inner wall of the separation tank 1. When the oil cleaned on the force plate 82 is too much, it will fall down due to gravity, which also prevents affecting the cleaning effect.

[0057] The positioning ring A21 is provided with avoidance grooves A211 and positioning grooves 212. There are at least three avoidance grooves A211 and positioning grooves 212. When in use, the positioning grooves 212 are used to place the positioning frame 51. The positioning frame 51 is composed of at least three rods.

[0058] A positioning piece B6 is provided on the positioning ring A21, and the positioning piece B6 includes a pressure ring 61. An avoidance groove B62 is opened at the bottom of the pressure ring 61. The avoidance groove B62 is used to accommodate the positioning frame 51 to prevent the pressure ring 61 from being pressed on the positioning frame 51 higher than the top of the separation tank 1 when the pressure ring 61 is placed on the positioning ring A21. In this way, when the pressure ring 61 is pressed on the positioning frame 51, the positioning frame 51 is located in the avoidance groove B62, which can keep the pressure ring 61 lower than the top of the separation tank 1. A lifting block 63 is connected to the outside of the pressure ring 61 and is located in the avoidance groove A211. The lifting block 63 can facilitate the staff to pick up the pressure ring 61. A sealing ring 7 is placed on the top of the pressure ring 61 and corresponds to the position of the placement groove 14. The sealing ring 7 is made of rubber. In this way, when the top sealing plate 15 is connected to the top of the separation tank 1, the top sealing plate 15 squeezes the sealing ring 7, so that the position between the placement groove 14 and the top sealing plate 15 remains sealed and airtight.

[0059] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
