Double-stage oil-water separator

Abstract

The invention relates to a double-stage oil-water separator, comprising an oil-water separation chamber, wherein a water outlet pipe of a pump is communicated with the oil-water separation chamber, an oil suction floater is communicated with a water inlet pipe of the pump by an oil suction pipeline, an oil baffle plate is arranged in the oil-water separation chamber separating the oil-water separation chamber into a clear water chamber and a polluted water chamber, an overflow device is installed in the clear water chamber, and an oil scraping mechanism is connected with the oil-water separation chamber by an installing support. The double-stage oil-water separator of the invention combines the working principles of the existing two one-stage oil-water separators so that after an oil-water mixture extracted by the pump is primarily separated in the oil-water separation chamber, concentrated floating oil can be processed by secondary separation by the oil scraping mechanism. The double-stage oil-water separator has simple structure and high oil removal efficiency, and can greatly improve the quality of cleaning workpieces; the oil suction floater is transformed to be a sliding structure, thereby eliminating the influence of the oil suction pipeline on the weight of the floater and increasing the efficiency; and the invention also has the advantages of small volume, low manufacturing cost and convenient operation.

Description

technical field [0001] The invention relates to an oil-water separator, in particular to a two-stage oil-water separator which can separate oil-water mixture twice. Background technique [0002] The existing oil-water separator generally can only separate the oil-water mixture once, and belongs to the first-stage oil-water separator. It has two structures, one is composed of oil-absorbing float, pump, oil-water separation chamber, etc., and the pump is used to suck the oil-water mixture into the oil-water separation chamber for primary separation; the other is composed of oil-scraping mechanism, reducer, etc. Composition, using the reducer to drive the oil scraping mechanism to perform primary separation of the oil-water mixture. The separation effect of the former is poor, and the separated floating oil contains a large amount of cleaning liquid, and the design and manufacture of the oil-absorbing float is difficult; although the separation effect of the latter is good, th...

AI Technical Summary

Problems solved by technology

The separation effect of the former is poor, the separated oil slick contains a large amount of cleaning fluid, and the design and manufacture of the oil-absorbing float is difficult; although the latter has a good oil-water separation effect, the oil removal efficiency is low, and it is difficult to meet the needs of modern industrial production. needs
