Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand processing, in particular to a drying device. Background Art

[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. The color of quartz sand is milky white or colorless and translucent. Quartz sand is an important industrial mineral raw material, a non-chemical hazardous substance, and is widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgical construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries.

[0003] When the existing drying device is used to dry quartz sand, a lot of dust will accumulate inside the quartz sand. The blown dust will pollute the environment, which will cause lung cancer and other conditions after the workers who work around it for a long time inhale it. Therefore, the existing quartz drying process is usually carried out in a relatively sealed state. After the device works for a long time, dust and other related impurities will accumulate inside the processing device, polluting the internal environment of the device, thereby deteriorating the drying effect of the device.
