Abstract

The invention discloses an oil separator. The oil separator comprises a box body, a solid-liquid separation chamber, a water-oil separation chamber and a water discharge chamber are arranged in the box body, an oil collection trough and an oil-water separation device are arranged in the oil-water separation chamber, the oil-water separation device comprises an oil adsorbing plate, an oil scrapingplate, a vertical driving assembly and a horizontal driving assembly, the lower surface of the oil adsorbing plate is provided with an oil adsorbing sponge layer, the oil-water separation device further comprises an oil guiding tube, one end of the oil guiding tube is connected with the oil scraping plate, the other end of the oil guiding tube extends to the oil collection trough, and the oil guiding tube receives oil scraped off by the oil scraping plate and guides the oil into the oil collecting trough. The vertical driving assembly drives the oil adsorbing plate to contact the liquid surface in the oil-water separation chamber, the oil adsorbing sponge layer adsorbs the oil, the vertical driving assembly drives the oil adsorbing plate to rise, the horizontal driving assembly drives theoil scraping plate to abut against the oil absorbing sponge layer, and the oil adsorbed by the oil adsorbing sponge layer is scraped by the oil scraping plate, goes through the oil guiding tube, and is collected into the oil collecting trough, so the water doped in the separated oil is reduced, and the trouble of secondary oil-water separation is reduced.

Description

technical field

[0001] The invention relates to the field of oil-water separation, in particular to an oil trap. Background technique

[0002] The so-called oil separator is a special equipment for separating impurities, oil and water in the oily wastewater of catering. As long as the sources of catering wastewater include hotels, hotels, canteens, etc., according to incomplete statistics, the discharge of catering wastewater accounts for about 3% of the urban domestic sewage discharge, but the BOD5 (biochemical oxygen demand for five days) and CODcr ( The content of dichromate oxygen demand) accounts for about 1 / 3 of the total load. It can be seen that catering wastewater is a high-concentration pollution source and one of the main causes of water pollution around cities.

[0003] At present, oil-water separation is mainly based on the density or chemical properties of water and oil, using the principle of gravity sedimentation or other physical and chemical methods to rem...
