Reciprocating type pulsation high gradient magnetic separation system matched with solenoid type superconducting magnet

Abstract

The invention relates to a reciprocating type pulsation high gradient magnetic separation system matched with a solenoid type superconducting magnet. An ore pulp inlet and outlet channel matched with a pulsation system is arranged, so that the pulsation system can be arranged on a reciprocating type superconducting high gradient magnetic separation system, and pulsation of the ore pulp in a magnetic separation link and washing water in a washing link is realized. Two independent pulsation systems are arranged in a reciprocating system, the magnetic separation link and the washing link can be independently carried out, the pulsation system is composed of a pulsation motor 6, a pulsation box 5 and a pulsation drum membrane 4, the pulsation motor 6 and the pulsation box 5 can be placed at any position which can be connected with the pulsation drum membrane 4, the pulsation box 5 can be connected with a single or multiple pulsation drum membranes 4 by virtue of a pulsation connecting rod 11, the pulsation drum membrane 4 can be arranged in a high-gradient separation cavity 2, can also be arranged in a separation cavity inner barrel 7 and can also be arranged in any pipeline connected with the ore pulp in a superconducting magnetic separation region, under the action of the pulsation drum membrane 4, the ore pulp or washing water can enter and be discharged from the high-gradient separation cavity 2 by virtue of a central feeding pipe 10 and a casing pipe 9 between an inner barrel and an outer barrel of a reciprocating tank or by virtue of a separated casing pipe 9 between the inner barrel and outer barrel of the reciprocating tank and also can enter and be discharged from a magnetic separation region by virtue of a casing pipe 9 between the inner barrel and outer barrel of the reciprocating tank.

Description

technical field [0001] The invention belongs to the technical field of magnetic separation, and relates to a superconducting magnetic separation system, in particular to a reciprocating pulsating high-gradient magnetic separation system equipped with a solenoid-type superconducting magnet, which can realize strong magnetic field and high-gradient pulsating magnetic separation of materials to be selected. It can be used for strong magnetic separation systems in fields such as removal of impurities such as quartz sand and potassium feldspar, desulfurization of coal powder, and enrichment of magnetic minerals such as iron ore and nickel ore. Background technique [0002] Magnetic separation is a physical separation technology, which is based on the principle that magnetic substances are subjected to force in a magnetic field to separate magnetic substances from non-magnetic substances. In magnetic separation technology, the force on magnetic particles in a magnetic field can be...
