Permanent magnet opening gradient sorting device

Abstract

The invention relates to a permanent magnet opening gradient sorting device, comprising a magnetic separation column, a feeding system, a closed-air sorting baffle and a discharging bin, wherein the magnetic separation column is arranged on a vertically-arranged vertical column by connecting pieces; the feeding system is arranged at the position of a feeding inlet of the top part of a sorting cavity of the magnetic suspension column and consists of a vibrating material distributor and a closed-air variable feeder; the closed-air sorting baffle is arranged at the position of a discharging port of the lower end of the sorting cavity of the magnetic separation column and is adjustable for the position thereof; the magnetic separation column comprises a main magnetic pole, an auxiliary magnetic pole and the sorting cavity, wherein the main magnetic pole is constructed by permanent magnetic steel, the auxiliary magnetic pole is arranged oppositely to the main magnetic pole and is constructed by a plurality of magnetism-collected pins, and the sorting cavity is arranged between the main magnetic pole and the auxiliary magnetic pole; the main magnetic pole consists of a plurality of permanent magnetic steels which take a radial line as reference and are mutually superposed in series, and magnetic yoke pieces which are extruded among the permanent magnetic steels mutually superposed in a two-two mode; each group of magnetic steels are axially magnetized, the polarities of the magnetic steels at the upper side and the lower side of the same magnetic yoke piece are opposite, and strong lines of magnetic force are provided by an extrusion mode; and the magnetism-collected pins are fixed on a plurality of groups of adjustable magnetism-collected pin plates by an arrangement mode with equal intervals.

Description

Technical field: [0001] The invention relates to a permanent magnet open-gradient separation device applicable to the fields of material purification such as non-metallic ore and abrasive materials, coal powder desulfurization and the like. The device adopts the tower shape and the separation principle of suction and deflection, which can increase the material separation stroke and meet the requirements of separation accuracy and concentrate recovery rate. Background technique: [0002] In view of the permanent magnet system does not require excitation power consumption and cooling system, and has stable performance, compact and simple structure, low operating energy consumption, convenient operation and maintenance and many other advantages, the permanent magnetization of electromagnetic equipment is the relentless pursuit of people. Since the 1980s, some permanent magnet magnetic separation equipment has emerged, including some weak magnetic field magnetic separation equip...
