[0002] Quartz sand is quartz particles made by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is SiO2. Quartz sand is an important industrial mineral raw material, a non-chemical hazardous product, and is widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries.

[0003] The existing quartz sand screening equipment is equipped with a double-layer screening structure. The double-layer screening structure is correspondingly provided with an upper and a lower feed port, and the upper and lower feed ports are respectively connected to a feed pipe to transport the material to be screened into the equipment. Since the feed pipes of the upper and lower feed ports are respectively independently arranged, the disassembly, assembly and maintenance thereof are more complicated, and if the two feed pipes are connected to the same feeding equipment, uneven material distribution is prone to occur.

[0004] At the same time, the researchers of this program have developed a quartz sand screening equipment with a new double-layer screening structure. The double-layer screening structure inside the equipment is swingably connected to the inner wall of the box of the equipment and driven to swing by a driving mechanism. Therefore, if too much material is transported in the upper screening structure and less material is transported in the lower screening structure, it is easy to cause the equipment to swing more significantly.

[0005] Therefore, a material flow structure for horizontal action screening of quartz sand is proposed, which can be conducive to uniform feeding of materials, avoid large-scale shaking of equipment, and facilitate disassembly and maintenance. Utility Model Content
