Description

Quartz sand drying device Technical Field The utility model belongs to the technical field of drying equipment, and particularly relates to a quartz sand drying device. Background The quartz sand is quartz particles formed by crushing and processing quartz stone. Quartz sand is an important industrial mineral raw material and is not a chemical dangerous article, and is widely used in industries such as glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction chemical industry, plastics, rubber, abrasive materials, filter materials and the like. When the water content of the quartz sand exceeds 1%, water bridges are formed among particles, the particles are induced to be bonded and agglomerated by capillary force, and particularly, the quartz sand with the fine particle size (such as <0.1 mm) is difficult to evaporate after agglomeration due to the large specific surface area. Traditional drying device is when handling moist quartz sand, is difficult to effectively separate caking granule, leads to the material to be heated unevenly, and the evaporation of water in caking core area is slow, leads to whole stoving time to lengthen by a wide margin, and drying efficiency is showing and is reducing. In addition, the existing drying device is generally limited by factors such as site space, energy consumption cost and the like, and the capacity and heat exchange area of equipment are difficult to expand synchronously, so that materials cannot fully contact a heat source in a limited space, and uneven drying is further aggravated. Disclosure of utility model In view of the foregoing, to overcome the defects in the prior art, the present utility model provides a quartz sand drying device, so as to at least partially solve the problems set forth in the foregoing background art.
