Novel magnetic separating device

Abstract

The invention discloses a novel magnetic separating device. The device comprises a magnetic separating pool, wherein a backwashing device, a belt type magnetic filtering cloth, a mud collecting tank and two driving motors are arranged in the magnetic separating pool; sewage is stored in the magnetic separating pool; rotating rollers are correspondingly arranged on the two driving motors; the belt type magnetic filtering cloth is mounted on the rotating rollers and can rotate as the rotating rollers rotate; one driving motor is arranged below the sewage, and the other driving motor is arranged above the sewage; the belt type magnetic filtering cloth comprises an upper thin stainless steel plate, a flexible glue magnetic cloth and a lower thin stainless steel plate which are arranged from outside to inside in sequence; a plurality of filtering pores are formed in the belt type magnetic filtering cloth. With the adoption of the novel magnetic separating device, the problems of high water content rate of mud, high mud quantity and low magnetic recovering efficiency of an existing loading magnetic depositing technology can be solved; magnetic extraction and magnetic separation are conveniently carried out; the device is simple in structure, green, and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of magnetic separation of sewage, in particular to a novel magnetic separation device. Background technique [0002] With the scarcity of water resources, continuous economic growth and excessive population growth, the problem of water resource utilization is becoming more and more obvious. Therefore, it is necessary to vigorously develop sewage recycling technology to alleviate the increasingly prominent water shortage. Sewage reuse is not only an important measure to promote the coordinated development of economy, environment and society. [0003] The existing sewage magnetic separation technology mixes magnetic powder to form flocs, which are then sent to the magnetic separation device. The magnetic recovery efficiency is low, the water content of the sludge is high, and the sludge treatment effect is too poor. [0004] Patent application number 201510040906.0 discloses the technical field of sewage mag...

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 new type of magnetic separation equipment. The belt-type magnetic separation equipment is beneficial to the separation of magnetic powder and sludge, and solves the problem of high moisture content of sludge in the existing loading magnetic precipitation process and the problem of sludge. The problem of large amount of mud and low magnetic recovery efficiency is beneficial to magnetic refining and magnetic separation, simple structure, and environmental protection
