Maintaining and flushing method for dielectric-magnetic box of high-magnetism magnetic separator

Abstract

The invention aims at providing a maintaining and flushing method for a dielectric-magnetic box of a high-magnetism magnetic separator. The maintaining and flushing method comprises the following steps of A, keeping intermittent back flushing on the dielectric-magnetic box by using water when the magnetic separator normally operates; B, clearing up the positions of easily-blocked points according to ordinary-time flushing overhaul statistics, and fixedly flushing the easily-blocked points by using a high-pressure cleaner during halting for overhaul, wherein the flushing direction is opposite to the magnetic separation direction of the dielectric-magnetic box, and each point is flushed for 20-30min; C, carrying out movable high-pressure flushing on the dielectric-magnetic box in a direction opposite to the magnetic separation direction of the dielectric-magnetic box, and controlling a flushing track during moving to ensure that a water flow flushing track covers the whole dielectric-magnetic box; and D, if a water flow on a flushing position is found to have the color of slurry or an iron ore concentrate during movable flushing, showing that the point is still blocked, and carrying out movable continuous flushing on the periphery of the point until the flushing water flow has no colors. By using the method, the defect that the dielectric-magnetic box in the prior art is difficult to clear after being blocked is overcome; and the method is simple and convenient to operate as well as high in efficiency and speed.

Description

technical field [0001] The invention relates to the field of equipment washing, in particular to a maintenance and washing method for a magnetic box of a high magnetic separator. Background technique [0002] High magnetic separator is the main equipment used for magnetic separation of iron ore concentrate in the high magnetic iron separation process. The magnetic box in the equipment is magnetized by the magnetic field to absorb the iron concentrate in the pulp, and the iron concentrate adsorbed on the magnetic box is brought into the non-magnetic area by the turntable, and the ore is unloaded with flushing water and flows into the concentrate hopper. The unadsorbed ore pulp through the magnetic box automatically flows from the tailings hopper. Keeping the unobstructed magnetic box is a necessary condition for high yield and high grade iron ore concentrate. When the magnetic box is blocked, it needs to be adjusted. If the adjustment is not in place, the tailings will dire...
