Superconducting magnet apparatus capable of providing high-intensity magnetic fields and high magnetic field gradients

Abstract

The invention discloses a superconducting magnet apparatus capable of providing high-intensity magnetic fields and high magnetic field gradients. The superconducting magnet apparatus comprises a metal housing and an electromagnetic structure; an accommodating space is enclosed in the metal housing; a channel is formed in the middle of the accommodating space; the channel comprises an inlet and an outlet; the electromagnetic structure is arranged in the accommodating space in a sealed manner in a low-temperature superconductive environment; the channel passes through the center of the electromagnetic structure; the electromagnetic structure is a superconductive electromagnetic structure, and provides a first magnetic field and a second magnetic field distributed upwards along the axial direction of the channel in sequence; and the magnetic force directions of the first magnetic field and the second magnetic field are opposite. The electromagnetic structure of the superconducting magnet apparatus can provide two magnetic fields with opposite magnetic force directions simultaneously; and while ensuring high-intensity magnetic fields, the electromagnetic structure also can provide quite high magnetic field gradients due to the counteraction of the magnetic fields with opposite magnetic force directions.

Description

technical field [0001] The invention relates to the field of superconducting magnets, in particular to the structure of superconducting magnet devices with strong magnetic fields and high gradients. Background technique [0002] With the rapid development of the electronic industry and high-tech information industry, as well as the rapid replacement of electronic products, electronic waste has become the fastest growing waste in the world. On the one hand, electronic waste contains a large amount of available metals such as aluminum and iron, precious metals such as gold, silver and platinum, and materials such as glass and plastic, which have high recycling value. On the other hand, electronic waste contains heavy metals and other harmful and toxic components, such as lead, mercury, cadmium, polychlorinated biphenyls, etc. If discarded, piled up or treated unreasonably, it will seriously pollute the environment and endanger human health. Therefore, how to make electronic ...

Problems solved by technology

However, for traditional physical separation equipment, especially in the stages of magnet separation and eddy current separation, electromagnetic and permanent magnetic materials are mostly used to provide magnetic fields for separation. The magnetic field strength is low and the magnetic field gradient is limited, which is not conducive to fine Sorting of magnetic metal particles, non-magnetic metal particles and non-metal particle materials
