[0002] In many industrial and life processes, wastewater containing oil and water is generated. In the field of wastewater treatment, oil-water separators are crucial equipment. Oil-water separators usually use static stratification or physical filtration methods to separate oil and water. The principle is to use the density difference between oil and water to separate the oil and water in the oil-water mixture and absorb the grease in it.
[0003] The oil-water separator needs to extract the oil after separating the oil and water. Traditional oil-water separators often require accurate knowledge of the depth of the oil, which brings great difficulty and uncertainty to the operation. Because in actual applications, the depth of the oil layer may change due to different batches of wastewater, which is difficult to measure accurately. Once the measurement is wrong, it will affect the oil absorption effect. In addition, adsorbed oil will remain on the wall of the cylinder. This part of the residual oil will not only reduce the separation effect, but also require the introduction of water from the outside for cleaning, which increases the time cost and also affects the continuous normal operation of the equipment.
[0004] Therefore, it is necessary to provide a wastewater treatment oil-water separator to solve the above technical problems. Utility Model Content

A filter port 26 is provided on the top of the filter box 25. Wastewater first enters the filter box 25 to filter out impurities and then enters the separation tank 1 for oil-water separation.

[0027] The working principle of the wastewater treatment oil-water separator provided by the utility model is as follows:
[0028] When the wastewater enters the separation tank 1 after being filtered, due to the buoyancy of the float 7, the sliding block 6 slides on the cleaning shaft 4 and rises above the wastewater surface. After a period of standing, the liquid level in the tank is overall flat and no longer fluctuates. Due to the density relationship, the oil will float on the water surface. At this time, the buoyancy of the float 7 can only support the oil suction assembly to move down below the oil surface as a whole, and the oil suction port 9 can just absorb the oil through the external oil pump. The absorbed oil is discharged through the oil guide pipe 10 and the separated oil discharge pipe 13 for drying. The counterweight ring 11 can add counterweights according to the type of oil to make it just below the oil surface. The oil suction assembly does not need to measure the depth of the wastewater and the height of the oil, which saves many links. No matter how the position of the oil layer on the wastewater surface changes, the oil can be accurately and effectively sucked out.
