Oil-water automatic segregator

Abstract

The invention relates to an automatic oil-water separator which comprises an open water tank and a partition that is arranged inside the water tank, wherein, an oil-water mixture inlet and a water outlet are respectively arranged at the left side and the right side on the water tank; the partition separates an inner cavity of the water tank into a left cavity chamber and a right cavity chamber, wherein, the upper part of the left cavity chamber is communicated with an oil collection groove through a gap while the lower part of the left cavity chamber is communicated with the right cavity chamber through a water return port which is arranged at the lower bottom part of the partition; the left cavity chamber is internally provided with an oil-water filter device and the right cavity chamber is also internally provided with a baffle; a sealed water cavity chamber is formed by the baffle and the inner wall of part of the water tank; the water cavity chamber is internally provided with a communicating pipe which is communicated with the water return port and is of an open structure, in addition, the upper part of the communicating pipe is provided with a level regulation piece which is used for regulating the level of liquid inside the communicating pipe. Through 'a communicator' formed between the communicating pipe and the left cavity chamber, the height regulation of the oil-water level can be achieved easily by regulating the level regulation piece on the communicating pipe so as to meet the different requirements of oil-water separation.

Description

technical field [0001] The invention relates to an automatic oil-water separator. Background technique [0002] In the metallurgical industry, a lot of waste liquid mixed with oil and water is often produced. If this part of waste liquid is directly discharged back to pollute the environment, it is usually firstly treated by oil / water separation through an oil-water separator, and then discharged. The discharged oil It can also be recycled. In the prior art, the simplest oil-water separator includes a water tank, an oil outlet connected to the upper part of the water tank, and a water outlet connected to the bottom of the water tank. An oil-water mixture inlet is provided on the water tank, and an oil-water filter is arranged in the water tank. The oil-water filter device can make the oil and water stratify again, so that the stratified oil will be located in the upper part of the water tank due to its relatively small specific gravity, and the water will be located in the ...

Problems solved by technology

But the fly in the ointment is that when this kind of oil-water separator separates the oil / water layer, the height of the boundary layer between the two is fixed, and the liquid surface of the mixture of oil and water with different specific gravity in the water tank is at the same position, because of this , in the case of different oil-water separation degrees, if the purity of the oil discharged from the oil outlet is different, the oil-water separator cannot meet the requirements at all
