Description

Flushing device for trough body of magnetic separator

Technical Field

The utility model relates to the technical field of superconducting magnetic separation equipment, in particular to a magnetic separator tank flushing device.

Background

The magnetic separator is a screening device for removing iron powder in the recycled powdery particles; the working principle of the magnetic separator is mainly as follows: after the ore pulp flows into the tank body through the ore feeding box, under the action of water flow of the water flushing pipe, ore particles are in a loose state and enter an ore feeding area of the tank body; under the action of a magnetic field, magnetic ore particles are magnetically aggregated to form a magnetic group or a magnetic chain, and the magnetic group or the magnetic chain is magnetically acted in ore pulp to move towards a magnetic pole and is adsorbed on a cylinder; because the polarities of the magnetic poles are alternately arranged along the rotating direction of the cylinder, when the magnetic poles alternately generate magnetic stirring phenomenon, non-magnetic minerals such as gangue and the like which are mixed in the magnetic clusters or the magnetic links fall off in the turning process, and finally the magnetic clusters or the magnetic links which are attracted on the surface of the cylinder are the concentrates.

The magnetic separator is widely applied to resource recovery in wood industry, mining industry, kiln industry, chemical industry and food industry, is suitable for wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite and other materials with granularity of less than 3mm, can also be used for iron removal operation of coal, nonmetallic ore, building materials and other materials, and is one of the most widely used and highly-universal machines in industry.

The common type of the mining magnetic separator is a semi-countercurrent magnetic separator and a countercurrent magnetic separator, as shown in fig. 1, a flushing pipe 2 of the magnetic separator extends into a tank body 1 from a feeding end, and an anti-scouring wear-resistant protection is assembled at a water outlet of the flushing pipe 2; during the operation of the magnetic separator, ore pulp directly flushes the flushing pipe 2 at the feeding end, and the flushing and wear-resisting protection at the water outlet of the flushing pipe 2 cannot play a role; once the flushing pipe 2 is broken, water in the flushing pipe 2 is sprayed out from the broken part to wash the tank body 1, and the tank body 1 is washed and broken for a long time to cause ore pulp to leak.

Therefore, the design of the magnetic separator tank flushing device capable of avoiding the feeding end ore pulp from directly flushing the flushing pipe and prolonging the service life of the tank is a problem to be solved in the prior art.
