Working principle: The filtered sewage diffuses into the rear cavity from the front cavity. Since the baffle is higher than the height of the inlet of the connecting pipe, the dirty oil in the sewage overflows from the front cavity to the rear front cavity, and the rear front cavity After the reclaimed water is full and higher than the clean water outlet, the water will flow into the rear cavity. At this time, the dirty oil floats on the water surface due to its physical properties, so the dirty oil flows from the water surface of the rear and front cavity along the oil inlet plate into the inlet. The oil hopper assembly is finally collected from the oil inlet into the inner cavity of the oil storage shell to realize the separation of oil and water.

Since the oil inlet plate of the oil inlet bucket assembly is connected with the positioning rod through the positioning plate, the oil inlet plate and the outer wall of the oil storage shell are in an active connection state, and the oil inlet plate can swing slightly relative to the outer wall of the oil storage shell. When the oil inlet plate is at the plate, the oil inlet plate is gently lifted to scrape the oil near the oil inlet plate into the oil inlet hopper assembly, so that the oil is guided into the oil storage shell along the oil inlet plate, and the oil guiding effect is better. After the plate is reset due to its own weight, the nearby oil is scraped in again, and the oil guiding operation is repeated.
