[0043] The working principle of the above embodiment is:

[0044] (1) After the oil and water enter the tank body 1 through the feed pipe 5, the flocculant is added and the first motor 401 is started. The first motor 401 drives the first rotating rod 402 and the first sprocket to rotate together. The first sprocket drives the second sprocket and the second rotating rod 404 to rotate together through the chain. The second rotating rod 404 drives the first gear 405 to rotate together.

The second motor 204 drives the first bevel gear 205 to rotate, and the first bevel gear 205 drives the second bevel gear 206 and the threaded rod 207 to rotate together. When the threaded rod 207 rotates, it drives the movable plate 208 to move. The movable plate 208 slides on the outer surface of the limiting rod to increase the stability of the movable plate 208 when it moves. When the movable plate 208 moves, it drives the baffle 209 to move together. At this time, the baffle 209 moves away from the inclined block 201, which facilitates the flocculant to enter the interior of the tank body 1 through the inclined block 201, thereby facilitating the separation of oil and water.
