Chemical sewage solid-liquid separator

Abstract

The invention provides a chemical sewage solid-liquid separator. The solid-liquid separator comprises a precipitation mechanism, a scraping mechanism in sliding connection is mounted on the precipitation mechanism, and a limiting nut is mounted on the scraping mechanism; a servo motor is mounted on the precipitation mechanism, the servo motor is connected with the scraping mechanism through a transmission belt, and a hand wheel is mounted on the scraping mechanism; and four supporting columns capable of being telescopically adjusted are mounted at the bottom of the precipitation mechanism, anda rectangular plate used for supporting the sealing mechanism and the filtering mechanism is mounted on the supporting columns. A sewage sedimentation and treatment structure is improved, a sliding pipe is arranged on a supporting rod, an air bag is arranged at the bottom of the sliding pipe, and the air bag can float on chemical sewage, so that a suction nozzle can effectively prevent floating objects in the sewage, and the air bag can descend along with the sewage; and by the arrangement of an extrusion block B on the sliding pipe, when the air bag descends to the bottom, the extrusion block B extrudes a switch, so that the servo motor of a reciprocating lead screw is electrified with a hydraulic cylinder.

Description

technical field [0001] The invention belongs to the technical field of chemical sewage, and more specifically relates to a solid-liquid separator for chemical sewage. Background technique [0002] Chemical wastewater refers to the wastewater produced in the process of producing products in chemical plants, such as the oily wastewater in the production of ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank farms, air separation and air compressor stations, etc. Chemical sewage will be mixed with a large amount of sediment and floating matter. It is necessary to separate the solid and liquid of the chemical sewage through the sedimentation device and the filter screen, and discharge the chemical sewage after the solid and liquid separation. [0003] For example, the existing Chinese invention patent with patent number CN201410243728.7 discloses a modular corrosion-resistant separation and sedimentation device for solid-liquid separation of suspension...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a chemical sewage solid-liquid separator to solve the problem that after the existing chemical sewage settles, a layer of relatively viscous sediment will adhere to the sedimentation tank, and the switch will be manually controlled during cleaning. Turn on the switch of the scraper, and manually open the sewage outlet when taking out the sediment. It will be laborious to clean up. After the sewage settles, there will be a layer of floating matter floating on the water surface, and it will be together with the floating matter when draining. Discharged outwards, the follow-up cleaning will be more troublesome
