Description

Technical Field

[0001] The invention relates to the technical field of quartz sand production and processing, in particular to a feeding device for quartz sand production. Background Art

[0002] Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral, primarily composed of silicon dioxide. Depending on the purity and impurity content of the quartz sand, the silicon dioxide content typically ranges from 85% to over 99.9%. In addition to silicon dioxide, quartz sand may also contain small amounts of feldspar, mica, iron minerals, clay, and other impurities. The type and content of these impurities directly affect the quality and use of the quartz sand. The production and processing of quartz sand generally involves ore mining, crushing, screening, washing, purification, drying, and packaging.

[0003] In the prior art, quartz sand needs to be fed and processed by a conveying device during the processing of crushing and screening, and the conveyor belt is a commonly used device in the feeding device. Usually, the quartz sand material to be processed is poured onto one end of the conveyor belt, and then the conveyor belt in the rotating process transports the quartz sand material to the processing site. However, in the process of transporting the quartz sand material, the conveyor belt is prone to uneven distribution of sand and gravel on its surface, which leads to uneven force on the conveyor belt during rotation, thereby accelerating the wear of the conveyor belt and reducing the service life of the conveyor belt. If the staff manually disperses the sand, the workload increases, and the dispersion effect is poor. At the same time, the staff next to the conveyor belt are prone to inhaling dust, which is detrimental to their health. When the conveyor belt is transporting sand and gravel, its surface is easily stained. If some corrosive stains are not cleaned in time, the service life of the conveyor belt will also be affected. For this reason, we propose a feeding device for quartz sand production. Summary of the Invention
