Superconductivity electric-magnetic iron remover

Abstract

The invention discloses a superconductive electromagnetic iron remover, which comprises a magnetic field system, a drive system and a control system. A magnet winding coil in the magnetic field system is made of the superconductive material. An insulating layer is disposed outside the coil. A refrigerator is mounted on the iron remover. A superconductive coil is connected to the cold junction of the refrigerator. An exciter coil of the iron remover mainframe is made of superconducting wire material such as NbTi. The superconductive electromagnetic iron remover has high field intensity, strong iron removing ability, low energy consumption of the entire remover, small size, stable operation, etc., and can absorb iron impurities in the material efficiently. With the superconductive electromagnetic iron remover, iron removing effect can be greatly improved, operation cost can be greatly reduced, and potential safety hazard caused by iron impurities can be reduced to the least.

Description

1. Technical field [0001] The invention belongs to magnetic separation equipment, in particular to an electromagnetic iron remover. 2. Background technology [0002] As we all know, the iron removal effect of the iron remover is determined by the size of the magnetic field in the iron removal area. Electromagnetic iron remover will generate a lot of heat when it is working, if it cannot dissipate heat effectively, it will affect the service life and reliability of the equipment. The heat dissipation of the existing electromagnetic iron remover mainly includes air cooling, oil cooling, and self-cooling. Due to the limitation of the heat dissipation power P of the iron remover, its excitation power P'=I 2 R must not exceed the heat dissipation power P, so that the ordinary iron remover is limited to increase the current, so that it cannot generate a larger magnetic field. [0003] In recent years, the production and related application processes of superconducting materials...

Problems solved by technology

To achieve a better iron removal effect, the magnetic field at the bottom of the coal conveyor belt should reach 5000GS. Taking a coal conveyor belt with a width of 2 meters as an example, the distance between the bottom of the iron remover and the bottom of the belt must be at least 550mm, while the conventional electromagnetic iron remover if It is almost impossible to achieve a magnetic field of 5000GS at 550mm below the bottom of the iron separator. The weight of the computing equipment is more than 100 tons, and the power consumption exceeds 300KW; while the weight of the superconducting iron separator is only 5 tons, and the total power consumption is less than 10KW

Conventional electromagnetic iron remover is much higher than superconducting electromagnetic iron remover, both in terms of manufacturing cost and user's later energy loss
