Problems solved by technology

[0003] Although the above-mentioned oil-water separation device can be used to separate the cooling water and cutting oil in the cutting waste liquid, because the suction port of the floating plate is slightly higher than the liquid surface, the suction port is easy to suck air, resulting in The pump downstream of the floating plate is prone to failure (cannot self-priming, temperature rise failure, etc.)

Abstract

The invention relates to a two-stage oil-water separator, which comprises a first oil-water separation device, a second oil-water separation device and a pumping unit, wherein the first oil-water separation device comprises a first liquid storage barrel and a floating unit mounted in the first liquid storage barrel, the floating unit is provided with a stretching pipe and a floating body connectedto the stretching pipe, the second oil-water separation device comprises a first accommodating chamber and a second accommodating chamber, the bottoms of the first accommodating chamber and the second accommodating chamber are communicated to each other, the first accommodating chamber is provided with an oil outlet higher than the opening of a first liquid storage chamber, and the second accommodating chamber is provided with a liquid outlet between the oil outlet and a second bottom wall. According to the invention, the first oil-water separation device performs first oil-water separation,and the waste liquid is pumped to the second oil-water separation device by the pumping unit, and is subjected to second oil-water separation, so that the good oil-water separation effect can be achieved.

Description

technical field [0001] The invention relates to an oil-water separation device, in particular to a two-stage oil-water separator. Background technique [0002] For the treatment equipment of the processed cutting waste liquid, such as the patent case of China Taiwan Certificate No. M415739, a floating plate is suspended on the cutting waste liquid. The floating plate has a liquid inlet pipe and a liquid outlet pipe. Pipe for the cutting waste liquid to flow into the floating plate, the liquid outlet pipe is connected with the liquid inlet pipe, and a pump is installed on an oil-water separation device, and the pump is connected to the liquid outlet pipe through a communication pipe And the oil-water separation device, the pump is used to pump the cutting waste liquid into the oil-water separation device. [0003] Although the above-mentioned oil-water separation device can be used to separate the cooling water and cutting oil in the cutting waste liquid, because the suction...
