Intelligent iron ore concentrator

Abstract

The invention belongs to the field of iron ore grading devices, and particularly relates to an intelligent iron core concentrator which comprises a feeding pipe (1), a feeding cylinder (2), an outer shell (8) and an overflow cavity (3), wherein the feeding cylinder (2) is fixedly embedded in the outer shell (8), a cyclone region (5) is formed between the outer wall of the feeding cylinder (2) and the inner wall of the outer shell (8), an outlet of the feeding pipe (1) corresponds to an inlet of the feeding cylinder (2), a water supplying pipe (6) is fixedly arranged at the lower part of the outer shell (8) and corresponds to an outlet of the feeding cylinder (2), the overflow cavity (3) is communicated with the cyclone region (5), an electromagnetic system (4) is arranged along the circumferential direction of the overflow cavity (3) to form a concentration and dispersion magnetic field, a conical depression area is fixedly arranged at the bottom of the outer shell (8), the overflow cavity (3) is of a spiral winding structure along the outer shell (8), and a water outlet of the water supplying pipe (6) is tangent to the outer shell (8). The intelligent iron core concentrator has the advantages of energy conservation, small size, large treatment amount, no ore leakage, and convenience in installation and maintenance.

Description

technical field [0001] The invention belongs to the field of iron ore sorting equipment, in particular to an intelligent iron ore sorting machine. Background technique [0002] Electromagnetic concentrator is a new thing that has risen in China in the past ten years. There are basically two types of it: one is a magnetic separation column, and the other is called an electromagnetic helical column. Magnetic separation column is a new type of weak magnetic separation equipment. The equipment draws lessons from the sorting principle of magnetic-gravity combination and the dispersing effect of the moving magnetic field on magnetic minerals, and designs a new type of sorting equipment that periodically changes the magnetic field strength from top to bottom with different ore feeding conditions. And the sorting space of the electromagnetic helical column is a ring cylinder, because the electromagnetic coil is a lot of small coils perpendicular to the axis of the ring tube, the d...

Problems solved by technology

Magnetic dehydration tank, although the equipment is simple, but due to manual adjustment of unloading volume, water supply volume and magnetic system structure, improper control often leads to ore running, and the desliming effect is not ideal

Although the desliming effect of the magnetic separation column is superior to that of the magnetic dehydration tank, its structure is complex, the copper consumption is as high as more than 500 kilograms, the water consumption is large (about 8 tons of water are needed to select 1 ton of concentrate), and the equipment is large in size. On-site installation brings a lot of inconvenience, and there is also the phenomenon of running mines
