Conduction cooling high temperature superconducting electric-magnetic iron remover based on nitrogen fixation protection

Abstract

The invention discloses a high temperature superconductive electromagnetic deironing element, which comprises the following parts: superconducting magnet, programmed power and magnetic control computer (1), wherein the screwed pipe coil axle of vertical and horizontal superconductive magnet (4, 5) is perpendicular with power supplied by two programmed energy (2, 3); the spatial working magnetic field is formed in the magnetic shaft plane; the liquid nitrogen container (12) lies between low-temperature container (17) and thermal radiation screen (16), which is assembled on the thermal radiation screen (16); the thermal radiation screen (16) is suspended in the low-temperature container (17); the nitrogen fixation container (15) is loaded in the thermal radiation screen (16); the disc-type windings (14) is assembled in the nitrogen fixation container (15); the serial port of computer (1) is controlled by magnetic field to connect serial ports of two programmed superconductive powers (2) and (3), which can adjust the powers (2) and (3) to control the direction and strength of working spatial magnetic field.

Description

technical field

[0001] The invention relates to an electromagnetic iron remover used for removing ferromagnetic materials from coal in ports, wharves, thermal power plants or other materials, in particular to a conduction cooling high temperature superconducting electromagnetic iron remover utilizing nitrogen fixation protection. Background technique

[0002] In the field of coal transportation, with the reduction of coal resources, it is more difficult to mine, resulting in the increase of sundries contained in it. The international requirements for the purity of coal for export are constantly increasing, which makes the major coal production and transportation enterprises continuously improve the removal rate of iron impurities in coal. For example, in the removal of extremely small objects such as detonators and fuses in coal seams with a material thickness of about 500mm (there are strict requirements for this in export coal: the content of detonators shall not exceed 3 ...
