Electric permanent-magnet iron separator

Abstract

The invention provides an electric permanent-magnet iron separator. The electric permanent-magnet iron separator comprises a rack, a driving belt wheel, a driven belt wheel, an iron separation belt and a magnetic system body, wherein the driving belt wheel and the driven belt wheel are arranged at two ends of the rack; the iron separation belt is wound on the driving belt wheel and the driven belt wheel, and the head and tail ends of the iron separation belt are closed; the magnetic system body is arranged inside the bottom of the iron separation belt and comprises a permanent-magnet source, an electromagnetic coil which is wound on the periphery of the permanent-magnet source, and a magnetic conduction shell which is used for accommodating the permanent-magnet source and the electromagnetic coil; the direction of a magnetic field generated by the permanent-magnet source is parallel to the direction of the magnetic field generated by the electromagnetic coil. According to the electric permanent-magnet iron separator, a basic working magnetic field is generated by the permanent-magnet source, and the magnetic force can be automatically adjusted by virtue of energizing / de-energizing and change of the energizing direction, so that the functions of iron separation through normal excitation, strong excitation, short-time ultra-strong excitation, reversing excitation and the like are realized.

Description

technical field [0001] The invention relates to magnetic separation equipment, in particular to an electric permanent magnet iron remover. Background technique [0002] In the actual production process, various forms of electromagnetic iron remover are used to remove iron from materials. Electromagnetic iron remover is a kind of electromagnetic equipment used to remove iron parts in bulk non-magnetic materials. It is generally installed at the head or middle of the belt conveyor. The strong magnetic force generated by its electrification will pick up the iron parts mixed in the material and throw them out from the unloading belt to achieve the purpose of automatic removal, and can effectively prevent the conveyor belt from being scratched longitudinally and protect the normal operation of crushers and grinders. Work. However, once the power of the traditional electromagnetic iron remover is cut off, the magnetism of the main body will disappear, and the iron-absorbed parts...

Problems solved by technology

[0003] Based on this, it is necessary to provide a magnetic field that can also generate a magnetic field during a power failure and solve the problems of the traditional electromagnetic iron remover once the power is cut off, the main body magnetism disappears, the iron-absorbing parts fall off and cause secondary pollution, and the magnetic force of the permanent magnet iron remover is difficult to adjust.
