Quartz sand cleaning device

Abstract

The invention provides a quartz sand cleaning device, which comprises the following steps of: loading quartz sand to be treated into a cleaning frame, installing the cleaning frame on a stirring coverafter the quartz sand is loaded, placing the cleaning frame into a first cleaning tank through lifting equipment, starting a rotating motor, driving a stirring shaft to stir the quartz sand, liftingthe cleaning frame out of the first cleaning tank through lifting equipment after the reaction is complete, and then moving the lifting equipment, so that the cleaning frame can enter a second cleaning tank, and after entering the second cleaning tank, fully removing residual acid on the surface of the quartz sand through cleaning water, so that the quartz sand can enter the next working procedure. As the cleaning tank of this embodiment integrates the first cleaning tank and the second cleaning tank, the steps of acid washing and water washing can be directly completed in one set of equipment, thus avoiding quartz sand from being respectively carried out in two different equipment in the cleaning process, thus greatly improving the cleaning efficiency of quartz sand. Meanwhile, the equipment cost for quartz sand processing is also reduced.

Description

technical field [0001] The invention relates to the technical field of quartz sand processing, in particular to a quartz sand cleaning device. Background technique [0002] As an important industrial mineral raw material, quartz sand is widely used in metallurgy, construction, chemical industry, plastic processing and other fields. Its main component is SiO 2 Because there are a lot of impurities in the quartz raw material, in the process of quartz sand processing, it is usually necessary to remove impurities and purify by purifying acid solution (acidic mixture such as sulfuric acid and hydrofluoric acid). A large amount of mixed acid remains, so the pickled quartz sand needs to be washed with water before drying. In the traditional quartz sand cleaning process, such as the quartz sand cleaning device disclosed in the patent CN108284102A, the quartz sand is subjected to acid leaching treatment and spray water washing once, resulting in low cleaning efficiency, and the aci...

Problems solved by technology

In the traditional quartz sand cleaning process, such as the quartz sand cleaning device disclosed in the patent CN108284102A, the quartz sand is subjected to acid leaching treatment and spray water washing once, resulting in low cleaning efficiency, and the acid liquid and spray water are recovered together, resulting in acid liquid The increase in the demand for quartz sand further leads to the high production of quartz sand
