Abstract

The invention discloses an environment-friendly type automatic quartz sand drying device and a quartz sand drying method. The environment-friendly type automatic quartz sand drying device comprises adrying chamber; a feeding inlet is formed in the top of the drying chamber, a discharging outlet is formed in the bottom of the drying chamber, and the feeding inlet and the discharging outlet are both provided with dedusting cavities and material chutes connected with the dedusting cavities; the drying chamber is internally provided with a feeding barrel connected with the feeding inlet, and a plurality of distribution discs arranged with the feeding barrel as the center; the distribution discs are sequentially arranged in the vertical direction according to the diameter from small to large;and the portions, corresponding to the space formed by the adjacent distribution discs, of the inner wall of the drying chamber are provided with a plurality of air blowing ports and the like. The environment-friendly type automatic quartz sand drying device has the unique layered air blowing drying, closed dust prevention, washing cleaning and other designs, the drying efficiency is high, the automation degree is high, environment pollution is small, practicability is high, and the environment-friendly type automatic quartz sand drying device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of quartz sand processing machinery, in particular to an environment-friendly automatic quartz sand drying device and a quartz sand drying method with novel design, high drying efficiency and low emission pollution. technical background [0002] Quartz sand is an important industrial mineral raw material. In industry, quartz sand is usually divided into: ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused silica sand and silica powder. Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO2, which has high fire resistance and is not a chemical hazard. It is widely used in glass, casting, ceramics, and refractory materials. Ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. [0003] Quartz sand can generally be made of natural quartz ore throug...

Problems solved by technology

Among them, drying is an important step that affects the quality of quartz sand. The existing drying methods are mostly hot air drying. During the drying process, the contact area between quartz sand and air flow is not large, and there are shortcomings such as uneven drying and low drying efficiency. Moreover, the quartz sand dust produced in the drying process is likely to cause environmental pollution and is harmful to human health, so it needs to be improved.
