Description

Multiple scrubbing device for quartz sand

Technical Field

The invention relates to the technical field of desliming of quartz sand, in particular to a multiple scrubbing device for quartz sand.

Background

The quartz sand is quartz particles formed by crushing and processing quartz stones. Quartz is a non-metallic mineral, a silicate mineral that is hard, wear resistant, and chemically stable. The color of the quartz sand is milky white or colorless translucent, the Mohs hardness is high, the quartz sand is an important industrial mineral raw material and a non-chemical hazardous article, and the quartz sand is widely used in the industries of glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, grinding materials, filter materials and the like.

In the production process of quartz sand, need clean quartz sand, make the impurity and the iron oxide of material surface adhesion drop, the material edges and corners is smooth, reaches the pure effect of material, improves the purity of quartz sand, and the stirring mode commonly used on the market cleans but has following defect:

1. the conventional multistage stirring scrubbing desliming is used as a desliming process of ores and is earlier and more common in application, but the conventional stirring scrubbing desliming effect is not obvious for the gangue minerals embedded in nano-scale in gaps and holes on the surface of quartz. The scrubbing principle is that mortar is intensively stirred in a box body through paddles to force mineral particles to move at a high speed, the mineral particles collide with each other in the movement, clay gangue particles attached to the surface are dissociated through friction, and then the argillaceous gangue is removed through a hydraulic classification method according to the difference of the particle sizes and the densities of the clay gangue and quartz sand. The desliming effect of the scouring machine is controlled by two factors of scouring time and pulp concentration: the scrubbing concentration is generally between 50% and 60% with good effect; the scrubbing time is not longer to meet the product quality requirement in principle. This is true for quartz sand ore, where the scrub-desliming process can only remove the larger surface gangue particles even under the best process conditions. But has little effect on the nano-scale gangue embedded in gaps and holes on the surface of the quartz sand. So that approximately half of clay gangue in the quartz sand can not be effectively removed;

2. the existing quartz sand impacts the falling sand material through stirring scrubbing or water flow floating, so that light impurities and fine sand float upwards and are separated from the sinking large-diameter sand particles. However, in the existing sand desliming process, due to disordered water flow, the phenomenon of turnover occurs, the water surface is difficult to stabilize, too many bubbles are in the water and carry too much air, the air is pumped into the slurry pump by a pump, so that the working pressure of the slurry pump cannot be stable, the discharging is intermittent, the discharging is better than that of a faucet, when more air or bubbles are contained, the discharging is intermittent, the grading effect is seriously influenced, the product quality is low, the gradually-improved process requirements are difficult to adapt, and the slurry pump has greater risk of cavitation erosion and non-pumping interruption;

3. the currently used quartz sand scrubbing mode is complex in structure, the scrubbing effect cannot be achieved by prolonging the scrubbing time, the quartz sand is generally conveyed to the next procedure only by simple stirring scrubbing, the smoothness of quartz sand particles and the scrubbing effect of impurities are reduced, the scrubbed quartz sand has serious mud content exceeding the standard, the grading precision is poor, the variety is few, and the product quality is unstable.

Based on the background, the quartz sand multiple scrubbing device has practical significance and wide prospect.
