The driving motor 5 may be a gear motor capable of forward and reverse rotation.
The upper surface of the spin chuck 3 is circumferentially distributed with a plurality of straight rails 31, and in the present embodiment, 8 straight rails 31 are provided in total. Each of the straight rails 31 is arranged in the radial direction of the spin chuck 3, and 8 straight rails 31 are uniformly distributed in the circumferential direction of the spin chuck 3 at equal angles. Each straight track 31 is provided with a movable claw 24 and a return spring 32, and the movable claw 24 and the straight tracks 31 form a sliding pair, so that the movable claw 24 can reciprocate along the straight tracks 31. The return spring 32 is disposed in the straight rail 31, one end of the return spring 32 is supported on the movable claw 24, and the other end is supported on the end of the straight rail 31 near the axis, which is in a compressed state, and the elastic direction is the same as the direction of the straight rail 31.

In actual use, the accumulated water at the bottom is not higher than the height of the rotary chuck 3 as much as possible.
3) After dehydration is completed, the separated liquid is allowed to stand for a certain time in a water collecting area at the bottom of the cylindrical tank body 1, so that oil-water delamination is realized. After layering, grease is discharged and collected through the oil delivery hose 12 by the oil inlet funnel of the oil delivery hose 12 floating at the oil-water interface.
