[0002] The skimming oil tank is one of the important process equipment for oil-containing sewage treatment in oil and gas field surface engineering. Its principle is to use gravity sedimentation to separate crude oil and suspended solids in sewage. Therefore, the oil-containing sewage exists in the skimming oil tank in the form of a water layer, an oil-water mixed layer, and an oil layer from bottom to top.

[0003] After retrieval, the utility model patent with the patent number CN215975078U and the name of a new type of skimming oil tank for oilfield sewage treatment includes a treatment tank. Through research and analysis, it is found that although it can effectively remove the oil stains adhering to the oil removal mesh plate, thus avoiding the blockage of the oil removal mesh plate, improving the aeration effect, improving the efficiency of the oil removal line, and making the oil-water separation more sufficient, there are still the following defects to a certain extent.

[0004] For example, it is not convenient to disassemble and assemble the oil removal mesh plate inside the skimming oil tank. When replacing the oil removal mesh plate in the above-mentioned skimming oil tank, personnel need to remove it inside the tank. Due to the small space inside the tank, the operation is time-consuming and laborious, increasing the labor intensity of personnel. Moreover, it does not have an anti-overflow function and cannot quickly pump out the excess oil-containing sewage in time. To solve the above technical problems, we designed a skimming oil tank with an anti-overflow structure. Content of the Utility Model

There is no need for personnel to operate inside the tank body, which is more time-saving and labor-saving, reduces the labor intensity of personnel, and improves the disassembly and assembly efficiency.

[0014] When the sewage level injected into the tank body contacts the liquid level sensor, the first electric valve closes, and the liquid pumping pump pumps the sewage in the tank body into the storage oil tank. When the liquid level is lower than the liquid level sensor, the drain valve opens, and the sewage in the storage oil tank flows into the tank body through the oil inlet pipe for treatment. This can prevent the sewage in the tank body from overflowing and timely discharge the excess sewage. Brief Description of the Drawings
