Description

Technical Field

[0001] This utility model relates to the field of drying technology, and more specifically, to a drying device for quartz sand production. Background Technology

[0002] Quartz sand is an important industrial mineral raw material, mainly produced from natural quartz stone through crushing, screening, washing, and processing. Quartz sand has a wide range of applications, including the glass industry, foundry industry, construction industry, and chemical industry. Drying is a crucial step before the production, storage, or specific application of quartz sand, primarily to remove free moisture and ensure product quality and performance.

[0003] Traditional quartz sand drying equipment relies on external hot air furnaces or burners to heat the air, requiring heat to be transported through long pipelines, resulting in heat loss. Quartz sand requires stirring to accelerate drying, but traditional equipment lacks sufficient stirring intensity, easily causing the quartz sand to clump or stick to the walls, requiring manual intervention. Furthermore, the hot, humid exhaust gas from traditional drying equipment is directly discharged into the atmosphere without recovery, leading to resource waste. Therefore, there is an urgent need to design a drying equipment for quartz sand production to solve these problems. Utility Model Content
