Method and device for permanent-magnet arc-shaped groove inner surface axial sorting

Abstract

The invention relates to a method and a device for permanent-magnet arc-shaped groove inner surface axial sorting. The method comprises the following steps: the sorted materials flowing through the field intensity of the inner surface of a rotating separating drum (2) and the sorted materials in a gradient area are absorbed by using the energy on the inner surface of a permanent magnet arc-shaped groove (1); the materials with lower specific susceptibility flow out from a low-magnetic material outlet (9) through a sorted material channel (13), and the materials with higher specific susceptibility are absorbed on the rotating separating drum (2), directly fall to a high-magnetic silo (7) by means of the own gravity, flow through a high-magnetic material outlet (8) and then are collected, therefore, the purpose of sorting the materials with different specific susceptibility is achieved. The invention has the advantages that the yield and the recovery ratio are greatly improved; the sorting range can be extended, and the sorting loss of the valuable substances is reduced; no sorting missing exists, and the sorting effect is good; the overall inclination angle theta is adjustable, the field intensity and the gradient can be changed, and the region angle of the field intensity and the gradient is 10-350 degrees; the permanent-magnet arc-shaped groove adopts the open loop design, therefore, the permanent magnet material is saved; and the separating drum is not required to be eccentrically arranged and can be easily manufactured and installed.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an axial separation method and equipment using the energy of the inner surface of a permanent magnet arc-shaped groove to separate cylinders. Background technique [0002] Traditional permanent magnet separators or sorting systems generally inlay permanent magnet materials on the outer surface of cylinders or rollers, and use the energy generated by the outer surfaces to separate substances with different magnetic susceptibility coefficients. [0003] The traditional permanent magnet sorting machine or sorting system has two feeding methods, that is, the feeding method on the outer surface of the permanent magnet cylinder and the feeding method under the outer surface of the permanent magnet cylinder. The feeding method on the outer surface of the permanent magnet cylinder, the selected material can directly contact the cylinder on the outer surface of ...

AI Technical Summary

Problems solved by technology

The feeding method on the outer surface of the permanent magnet cylinder, the selected material can directly contact the cylinder on the outer surface of the magnet, the residence time on the cylinder on the outer surface of the magnet is short, the adsorption capacity is large, and the sorting effect is poor. This method can increase the yield , but the sorting effect is not good; the feeding method is under the outer surface of the permanent magnet cylinder, there is a certain gap between the selected material and the magnetic outer surface, the sorting effect is better, but the yield is low, and the target product is lost more
