Industrial sewage treatment device

Abstract

The invention discloses an industrial sewage treatment device. The sewage treatment device comprises a sewage collection box and sewage treatment equipment connected with a water outlet below the sewage collection box, wherein the sewage collection box comprises a water inlet and a first water outlet at the lower side; a water inlet valve is mounted in the water inlet; the lower end of the first water outlet is fixedly connected with a water inlet pipe; the water inlet pipe enters a first sewage treatment cavity through an opening formed in the upper end of the first sewage treatment cavity; electric screw rods are arranged at the left and right sides by taking the vertical central line of the water inlet pipe as the symmetric axis; metal impurities fall into a collection groove and the impurities can be taken out from a drawing box in time and are utilized for the second time; after sewage without the metal impurities enters a second sewage treatment cavity, oil removal is carried outthrough an oil removal net and the oil removal net can be manually taken out from a sliding groove in a sliding manner through a through hole and then is replaced; the sewage treatment equipment forproduction of mechanical spare parts has a simple principle; iron scrap and the metal impurities are utilized for the second time so that resources are saved and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to sewage treatment equipment for mechanical spare parts. Background technique [0002] In the production process of mechanical parts, a large amount of sewage will be produced. Due to the internal properties of mechanical parts, a large amount of oil and iron filings will be produced in the sewage. Most of the sewage treatment equipment in the prior art is difficult to meet the above requirements. Decontamination requirements, or complex circuits and device controls are required for multi-level sewage treatment, the process is complex, and the cost and technology required are high. Therefore, we propose an industrial sewage treatment device to solve the above problems . Contents of the invention [0003] The purpose of the present invention is to provide a kind of sewage treatment equipment for mechanical spare parts, so as to solve the problems raised in the above-ment...
