Oil-water separator

Abstract

The invention discloses an oil-water separator, which belongs to the technical field of waste treatment. The oil-water separator comprises a case, wherein the upper part of the case is a filter cavity and the lower part of the case is a separating cavity; and a combined tank consisting of an oil storage tank, a mixing tank and a water storage tank, connecting pipelines and valves are arranged in the separating cavity. The oil-water separator has the advantages of high separation efficiency, complete oil-water separation, no need of loading or transporting waste cooking oil, no need of chemical agent or energy source, no secondary pollution, low cost and convenient use. The separator can treat the waste cooking oil produced by catering services in situ; one equipment can simultaneously realize solid-liquid separation and oil-water separation; the recovered grease can be used as a raw material for the chemical industry; and the discharged sewage meets the national emission standard. The separator can retain food residues and grease of kitchen wastes of canteens, hotels and restaurants from the source and reduce grease content in the sewage. The separator realizes effective management of the kitchen wastes, enhances operability of the management, prevents the waste cooking oil from returning to dining tables, ensures food safety and effectively reduces pollution of kitchen sanitary sewage to environment.

Description

Technical field [0001] The invention relates to a domestic waste treatment device, in particular to a device for separating oil and water from hogwater produced in the catering industry, and belongs to the field of waste treatment devices. Background technique [0002] At present, the slush water produced by the catering industry contains a lot of oil, and direct discharge will cause blockage of sewer pipes, waste of resources, and pollute the environment. Most of the buckets are now used to hold hogwash, transport it to the recovery place, and then use simple manual separation methods to separate the oil and water, and the liquid needs to be pumped. In order to improve the separation efficiency, chemical agents need to be added. The disadvantages are that the amount of hogwash is large and a large-capacity container is required, so the labor intensity of moving is large, the transportation volume is large, the efficiency of manual separation is low, the separation is not c...
