Description

Technical Field

[0001] The invention relates to the technical field of quartz sand purification, in particular to high-purity quartz sand purification and pickling equipment. Background Art

[0002] The pickled quartz sand is screened by multiple advanced processes, and then the impurities of quartz are treated with a mixture of pickling solution, sulfuric acid and other strong acid and quartz sand, and then treated with water to remove the acidity, so that the quartz sand is purer, high purity and uniform particles. The silicon content is as high as 99.9% from the sampling inspection. It is an indispensable material for quartz tube production and semiconductor materials, such as a high-purity quartz sand purification pickling device with application number CN202122194182.9. The quartz sand pickling equipment described therein, when soaking the quartz sand with pickling solution, has a single stirring direction. The impact of the single stirring direction is that the quartz sand will accumulate in a layered and increasing density inside the container, so that each layer of quartz sand contacts the pickling solution in a different area, resulting in insufficient quartz sand soaking and reducing the purification effect of pickling.
