[0002] Quartz sand is a non-metallic mineral, the main component of which is silicon dioxide. It is hard, wear-resistant and has stable chemical properties. Quartz sand is a silicate mineral that is hard, wear-resistant and has stable chemical properties. It is widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, construction, chemicals, plastics, rubber, abrasives, filter materials and other industrial fields. Quartz sand can be divided into transparent sand, semi-permeable sand, porcelain white sand, etc. according to different transparency and whiteness. It has a wide range of classifications and applications and is one of the indispensable raw materials in the industrial and construction fields.

[0003] In the process of quartz sand purification, although flotation washing technology is a commonly used and effective method to remove suspended impurities, the traditional flotation washing technology relies on a stirring mechanism to stir the quartz sand and impurities to make the suspended impurities float to the surface of the liquid better. However, in this process, some quartz sand will inevitably be stirred into the upper liquid, and the power of the stirrer needs to be increased, which will further increase the grinding loss of quartz sand. When the upper liquid is separated by a scraping mechanism, the liquid containing quartz sand is discharged, resulting in a waste of quartz sand. The output of quartz sand decreases after flotation washing, which in turn increases production costs. Utility Model Content
