Separation equipment with drum magnetic grate

Abstract

The invention discloses separation equipment with a drum magnetic grate. The separation equipment comprises a tank. A sewage inlet and a clear water discharge outlet are formed in the tank, the drum magnetic grate is transversely erected in an inner cavity of the tank, the sewage inlet is formed in a side wall of the tank and is hermetically communicated with the drum magnetic grate, the drum magnetic grate comprises a grate central shaft, the grate central shaft is transversely rotationally supported in the inner cavity of the tank, a plurality of magnetic rings sleeve the grate central shaft, gaps are reserved among the arrayed magnetic rings, permanent magnets are uniformly distributed on the magnetic rings along circular ring directions, the magnetism of each permanent magnet is opposite to the magnetism of the corresponding adjacent permanent magnet in the identical directions, residue scraping teeth are arranged among the upper ends of the adjacent magnetic rings, and residue collecting hoppers are arranged below the residue scraping teeth; the grate central shaft is further axially provided with a spiral conveyor, a housing case of the spiral conveyor is communicated with the bottoms of the residue collecting hoppers, an end of the spiral conveyor extends out of the tank, and a residue discharge outlet is formed in the spiral conveyor. The separation equipment has the advantages that the separation equipment is simple in structure, convenient to manufacture and applicable to high sewage treatment load, and sewage can be effectively comprehensively cleaned.

Description

Technical field [0001] The invention relates to a sewage treatment equipment, in particular to a rotating drum magnetic grid separation equipment. Background technique [0002] The scarcity of water resources, the continuous economic growth, and the increase in population will inevitably lead to the continuous increase of water prices. Therefore, vigorously developing the sewage reuse business can not only save limited water resources and alleviate the increasingly prominent water shortage, but also Reduce sewage discharge, reduce pollution to surrounding water bodies, improve human living environment, and save a lot of water resources. Sewage reuse is an important measure to promote the coordinated development of economy, environment and society, and there are huge business opportunities. [0003] Magnetic separation technology can be said to be an older and more mature technology. It was first used in mineral processing and china clay industry. Magnetic separation technology is ...

AI Technical Summary

Problems solved by technology

At present, the existing magnetic separation water treatment equipment uses disk drives as the main sewage purification equipment. The manufacturing process of disk drives is relatively complicated, the manufacturing cost is high, and there are many slag leakages, which affect the purified water quality. Affected by the structure of the disk, the treatment limited water
