Magnetic pulsation countercurrent sorting device

Abstract

The invention discloses a magnetic pulsation countercurrent sorting device. The device comprises a sorting column; a pulsation device used for providing pulsation flow for a flow field in the sorting column is arranged on the sorting column; the pulsation device is connected with an inner cavity of the sorting column; and a magnet exciting coil capable of forming a magnetic field in the sorting column is further arranged on the sorting column. The density, the granularity and the magnetic property of separated particles are fully utilized, dispersion, layering and separation of particles with different properties in the sorting column are achieved through regulation and control of the magnet exciting coil on a magnetic field in the sorting column and regulation and control of the pulsation device on fluidized water, and finally, flow membrane separation is conducted through a countercurrent separation device to enhance the sorting process. By effectively combining the magnetic force characteristic, the pulsating water flow characteristic and the inclined surface flow characteristic of the countercurrent separation device, the magnetic pulsation countercurrent sorting device has the advantages of high sorting precision, good separation effect and the like under the cooperation of various effects, and can be widely applied to the industries such as the mining industry, environmental protection, chemical industry and medicine.

Description

technical field [0001] The invention relates to the technical field of mineral separation, in particular to a magnetic pulse countercurrent separation device. Background technique [0002] The countercurrent separation column is a new type of solid-liquid fluidized bed separation equipment with high processing capacity. It was invented by Professor Galvin of Australia in 2002 and used for coal separation. It has no moving parts, simple structure, small footprint, and low energy consumption. Low, no pollution and other advantages. Compared with the traditional fluidized bed equipment, the countercurrent separation column adds a parallel inclined plate on the upper part of the bed, and uses the flow film separation of the inclined plate to obtain better separation accuracy and far exceed the traditional fluidized bed. The processing power of the device. [0003] However, the traditional countercurrent separation column controls the separation of the separation bed and the in...

Problems solved by technology

[0003] However, the traditional countercurrent separation column controls the separation of the separation bed and the inclined plate layer by adjusting the operating parameters such as the concentration and flow rate of the feed, the flow rate of the underflow, and the flow rate of the ascending water. It can be determined by the particle density and particle size properties of the feed, and can only provide stable fluidized water, which not only makes the equipment unsuitable for working conditions with high viscosity and poor dispersion effect, but also for small density differences and magnetic differences. The sorting effect of large raw materials is also very unsatisfactory

Therefore, the applicability and sorting effect of the sorting equipment need to be further strengthened
