Rapid magnetic separation device

Abstract

The invention discloses a rapid magnetic separation device. The rapid magnetic separation device comprises a magnetic separation water tank, a magnetic plate assembly, a slag scraper, and a sludge collecting hopper; sewage for magnetic separation and the magnetic plate assembly are arranged in the magnetic separation water tank; the bottom of the magnetic separation water tank is provided with a water inlet; the magnetic plate assembly is composed of a plurality of magnetic plates in parallel; gaps between each pair of adjacent magnetic plates are used for forming fluid passages used for overflow of sewage; one end of the magnetic plate assembly is provided with a magnetic plate fixing device, and the other end is provided with an automatic hatch door used for discharge of magnetic sludge;the sludge collecting hopper is arranged under the automatic hatch door; the slag scraper is arranged on the magnetic plate assembly, and is capable of performing reciprocating motion from bottom totop along the side surface of the magnetic plate assembly. The rapid magnetic separation device can be used for adsorption interception of sludge flocculation containing magnetic powder, so that magnetic separation filtering is realized, problems of conventional settling pond filtering method that sludge water content is high, large amount of sludge is generated, and magnetic recovery rate is loware solved, large amount stable sewage filtering is realized, the structure is simple, and using effect is excellent.

Description

technical field [0001] The invention relates to the technical field of sewage magnetic separation, in particular to a rapid magnetic separation device. Background technique [0002] With the development of my country's economy and the accelerated pace of industrialization construction, my country's industrialization construction has brought a lot of environmental pollution, especially the pollution of water resources. Originally, my country's water resources are not rich, and a lot of pollution has caused water shortages in some areas of our country, and the conservation of polluted water resources has become an imminent problem. [0003] The existing sewage treatment adopts the method of chemical reaction, but this method takes too long, the effect is too poor, and the floor area is large, so it cannot really realize rapid sewage treatment. [0004] Patent application number: 201010251476.4 discloses a new type of magnetic separation sewage treatment device, including a ta...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a fast magnetic separation device. The plate type magnetic separation device can absorb and intercept sludge flocs containing magnetic powder, thereby achieving magnetic separation and filtration, and avoiding the traditional use of sedimentation tanks. It solves the problems of high moisture content of sludge, large amount of sludge and low magnetic recovery efficiency. It can filter a large amount of waste water stably. It has a simple structure and good use effect.
