Description

Permanent magnetism cylinder magnet separator concentrate washes and unloads ore device

Technical Field

The utility model relates to a permanent magnetism cylinder magnet separator concentrate washes unloads ore device belongs to metallurgical industry magnetite mineral processing equipment technical field.

Background

The permanent magnetic drum magnetic separator is a magnetic separation device commonly used in iron dressing plants, and magnetic ore particles are adsorbed to the surface of a roller and rotate along with the roller under the action of a magnetic field, and concentrate is discharged into a concentrate tank under the action of flushing water flow sprayed by a mineral discharge water pipe; in the traditional equipment, concentrate usually adopts duck-shaped water nozzles arranged in rows to spray water to the surface of a roller of a magnetic separator at a certain angle for ore unloading; the traditional ore water unloading device has the following defects: firstly, the ore discharge water of the ore dressing plant is mainly circulating water, the water contains more impurities, and the duck-shaped water nozzle is easy to block after being used for a long time, so that the phenomena of uneven ore discharge, ore hanging on the surface of the roller and the like are caused; secondly, due to the blockage of the duck-shaped water nozzle, workers need to frequently clean the duck-shaped water nozzle, so that the labor intensity is greatly increased; thirdly, the cleaning process needs to be stopped, so that the operation rate of the equipment is low, and the yield of the concentrate is influenced. In conclusion, the traditional concentrate flushing and unloading device cannot meet the use requirements of the existing magnetic separator.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a permanent magnetism cylinder magnet separator concentrate washes unloads ore device, rivers are stable, have avoided because of unloading the more jam of ore deposit aquatic impurity, can wash the concentrate on magnet separator cylinder surface totally, solve the problem that exists among the background art.

The technical scheme of the utility model is that:

a concentrate washing and unloading device of a permanent magnet drum type magnetic separator comprises a water supply main pipe, water distribution pipes, a buffer water tank, a buffer baffle, an overflow tank, an overflow port and an overflow guide plate, wherein the water supply main pipe is laid right above the buffer water tank, one end of the water supply main pipe is closed, the other end of the water supply main pipe is connected with a main water source through a valve, and the water supply main pipe is communicated with the buffer water tank through a plurality of water distribution pipes; the height of the overflow tank is the same as that of the buffer water tank, a buffer baffle plate which is vertically arranged is arranged between the overflow tank and the buffer water tank, and the overflow tank is communicated with the bottom of the buffer water tank; the upper portion of overflow case is equipped with the overflow mouth, and overflow mouth department is equipped with the overflow guide plate of slope arrangement.

And the included angle alpha between the overflow guide plate and the vertical direction is 40-80 degrees.

The overflow guide plate is fixed on the overflow box body.

And a reinforcing rib is arranged between the overflow guide plate and the overflow box body.

And the distance between the overflow port at the upper part of the overflow tank and the bottom of the overflow tank is three-fourths of the height of the overflow tank.

Adopt the utility model discloses, during the use, high pressure water source reachs the main pipe of water supply, flows in buffer tank through the distributive pipe, and buffer baffle between buffer tank and the overflow box has blockked because the too big splash phenomenon that causes of water pressure lets rivers from the steady flow direction overflow box overflow mouth in buffer tank bottom to form steady horizontal plane, then through overflow guide plate flow direction magnet separator cylinder surface, wash the concentrate on cylinder surface totally.

The utility model has the advantages that: the utility model discloses simple structure, installation change convenience, long service life have really realized that rivers are stable, water pressure is sufficient, have stopped because of the more risk of blockking up of ore unloading aquatic impurity, have reached the concentrate on magnet separator cylinder surface and have washed clean purpose.
