Electromagnetic particle screening device

Abstract

The invention discloses an electromagnetic particle screening device. A screening module comprises a screening part used for removing particles with the particle size smaller than the preset particle size from the particles. An electromagnetic conveying module comprises a conveying device and an electromagnet. The conveying device comprises a conveying part arranged below the screening part and used for conveying the particles falling from the screening part, and the particle size of the falling particles is smaller than the preset particle size. The electromagnet is used for adsorbing the particles with the particle size smaller than the preset particle size to the conveying part. Compared with a traditional screening and dust removing device, the electromagnetic particle screening device has the advantages that the electromagnetic technology is used for screening, adsorbing and conveying the damaged magnetic particles and dust, the screening and dust removing efficiency is higher, the particles and dust waste in the conveying device are collected thoroughly based on an automatic waste collecting method, and the electromagnetic dust removing and conveying module does not need to be specially cleaned by workers. The electromagnetic particle screening device is suitable for screening and removing dust in the magnetic particle materials, and is especially suitable for the closed environments or special environments where the workers cannot finish the operation due to radioactivity.

Description

technical field [0001] The invention relates to an electromagnetic particle screening device, in particular to an electromagnetic particle screening device used in a reactor using a solid particle flow target system. Background technique [0002] In a reactor using a solid particle flow target system, it is necessary to screen and dedust the particle target or particle coolant in time. Because: firstly, damaged particles will affect the fluid properties of particle flow; secondly, the circuit of particles is in a closed pipeline with different vacuum degrees, and damaged particles are easy to damage the vacuum differential system; thirdly, damaged particles will increase In the area of ​​large wear, the degree of wear is directly related to the area, and damaged particles are more likely to generate dust, which has a greater impact on system safety; fourth, damaged particles will affect neutron performance and related energy deposition and other parameters. Because the nucl...

Because: firstly, damaged particles will affect the fluid properties of particle flow; secondly, the circuit of particles is in a closed pipeline with different vacuum degrees, and damaged particles are easy to damage the vacuum differential system; thirdly, damaged particles will increase In the area of ​​large wear, the degree of wear is directly related to the area, and damaged particles are more likely to generate dust, which has a greater impact on system safety; fourth, damaged particles will affect neutron performance and related energy deposition parameters

Because the nuclear reactor is in a closed, high-temperature environment, and its radioactivity is extremely strong, ordinary screening and dust removal equipment should not be used in it
