Wind power sorting control method and system

Abstract

The invention provides a control method and system for wind power separation. The control method comprises the steps that the density and granularity of magnetic tracers in a tracer recovery device corresponding to each type of products obtained through separation are obtained; wherein the magnetic tracer is synthesized by a magnet and polyurethane according to a preset proportion; calculating the ratio of high-density magnetic tracers in the tracer recovery device corresponding to each type of products; calculating a first ratio of the number of the first high-density magnetic tracers to the number of the second high-density magnetic tracers; and the high-density magnetic tracer ratio in each type of products and the first ratio are compared with a preset threshold value corresponding to each type of products, and the air speed of the sorting equipment is reduced and / or the discharging amount of a discharging opening corresponding to each type of products is increased based on the comparison result. The discharging amount and the air volume can be intelligently adjusted, and therefore the sorting quality is improved.

Description

technical field [0001] The invention relates to the technical field of wind separation, in particular to a control method and system for wind separation. Background technique [0002] Wind coal preparation (wind shaker, air jigging and cascade separator, etc.) belongs to the category of dry gravity beneficiation, but its separation process is different from wet gravity beneficiation methods. The existing inclined wheels, vertical wheels, Gravity separation equipment such as shallow tanks and gas-solid fluidized beds, after the materials to be selected enter the separation equipment, light materials and heavy materials run in different directions in the medium inside the equipment according to different gravity, and achieve effective separation. Influenced by the density of the medium, the above methods cannot realize the separation of high-density objects, and the separation process requires water or medium, and the system is very complicated.

[0002] Wind coal preparation (wind shaker, air jigging and cascade separator, etc.) belongs to the category of dry gravity beneficiation, but its separation process is different from wet gravity beneficiation methods. The existing inclined wheels, vertical wheels, Gravity separation equipment such as shallow tanks and gas-solid fluidized beds, after the materials to be selected enter the separation equipment, light materials and heavy materials run in different directions in the medium inside the equipment according to different gravity, and achieve effective separation. Due to the influence of medium density, the above methods cannot achieve high-density material separation, and water or media are required during the separation process, and the system is very complicated

[0003] The separation principle of dry separation is more complicated than that of wet separation, and the requirements for product intelligence are also higher. machine, etc.) according to density-dominated layering, and the particle size and shape of the material will also interfere with the density-based layering behavior of the material, and after the material to be selected is layered according to the density-dominated layer in the height direction, the light and heavy material layers will be completely pasted. and with the change of the feeding properties, the height of the light-heavy material layer interface also fluctuates, it is difficult to feedback the numerical change of the cutting component through the detection of equipment parameters inside the equipment, and then it is impossible to realize intelligent detection, control and adjustment upgrade
