Oil-water separating device

Abstract

The invention discloses an oil-water separating device which comprises a cylinder. A waste water inlet is formed on one side of the top of the cylinder. A partition is mounted in the top of the cylinder. The space in the cylinder is divided into a waste water processing area and a purifying area by the partition. A cover plate is movably connected to the bottom of the partition. A filter screen layer is disposed in the waste water processing area at the waste water inlet end. A slag scraper is mounted at the cylinder top above the filter screen layer. The upper layer of the waste water in the waste water processing area is the oil layer. An oil collecting tank communicated with an oil discharge valve is disposed below the oil layer. A water discharge outlet is formed at the bottom of the purifying area. A filter element layer is mounted in the purifying area. An oil-free clean water outlet is formed outside the cylinder above the filter element layer. The oil-water separating device has the advantages that for the waste water containing oil, water, sludge and the like which are hard to separate, large-particle impurities are filtered through the filter screen layer, then upper oil is removed, small-particle substances are cleaned in the purifying area, the sludge large in density can settle at the bottom of the cylinder, and good oil-water separating effect is achieved.

Description

technical field [0001] The invention relates to an oil-water separation device. Background technique [0002] The oil-water separator is an instrument that separates oil and water. The principle is mainly based on the density difference between water and fuel oil. The separator uses the principle of gravity sedimentation to remove impurities and water. The sewage flows into the oil-water separation chamber through the inlet, leaving solid matter. Gravity separates a large amount of grease and floats on the surface, so the upper layer of grease must be continuously removed, otherwise the sewage will be surrounded by grease and it will be difficult to clean it. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an oil-water separation device with good separation effect. [0004] The technical scheme adopted in the presen...
