Abstract
The utility model discloses a device for producing molten obtuse quartz sand by taking a waste quartz crucible as a raw material, and belongs to the field of processing of molten quartz. The device consists of a crushing machine, an acid pond, a washing machine, a high-temperature sintering furnace, a vibration sieve and a magnetic separator. A production process of the molten obtuse quartz sand comprises the following steps of: crushing, pickling, washing, sintering at high temperature, melting and cooling the waste quartz crucible material, then performing crushing, screening and magnetic separation, and thus obtaining the molten obtuse quartz sand used by a quartz crucible. The specification of the quartz sand is 0.075 to 4.5 millimeters.. The device has the advantages that the investment is small because general equipment is used; a batch of high-quality molten obtuse quartz sand for the quartz crucible can be produced; and the quartz sand can replace imported high-purity quartz sand from the abroad and is used for producing the quartz crucible.
