Sewage treatment device for metal recovery based on magnetic induction line cutting principle

Abstract

The invention relates to the technical field of sewage, and discloses a sewage treatment device for metal recovery based on a magnetic induction line cutting principle. The sewage treatment device comprises a shell, wherein the shell is used for supporting and stabilizing the whole device, and through cooperative use of a first special-shaped wheel, a large gear, a limiting rod, a magnetic pole block and an electromagnet, metal can be collected in a unified mode. Hands do not need to stretch into water for salvaging manually, contact between skin and sewage is reduced, insufficient salvaging is avoided, and waste of metal substances is avoided. Through cooperative use of fan-shaped wheel baffles, the water flow is automatically controlled during sewage treatment, the situation that the water flow is too large and consequently the water flow is too rapid is avoided, thus reducing instability in metal collection, and improving practicability of the whole device. Through cooperative use of a first disc and a sleeve rod, the two steps of opening a water inlet and collecting metal are linked, so that the linkage performance of the whole device is improved, and the operation is simpler.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to a sewage treatment device for metal recovery based on the principle of cutting magnetic induction lines. Background technique [0002] Sewage is usually required to be purified before it is discharged, so that the sewage can reach the quality of being discharged into a certain water body or reused. In ordinary sewage treatment, sewage is often mixed with some discarded metal impurities. However, traditional sewage The filter device cannot separate the metal alone, but it is filtered together with other waste residues. People usually still need to salvage the metal manually. First of all, it is easy to cause direct contact between the skin and the sewage during salvage, because the sewage contains a lot of pollution. It is easy to cause skin infection etc., secondly, there is the shortcoming that scrap metal cannot be automatically collected or collected incompletely in the prior a...
