Pickling device for quartz sand production

The invention relates to the field of quartz sand processing, in particular to a pickling device for quartz sand production. The technical problems that in the working process of an existing quartz sand pickling device, the caking phenomenon occurs in the reaction process of quartz sand and an acid solution, meanwhile, the acid solution is difficult to permeate into the quartz sand, the quartz sand pickling effect is poor, and meanwhile iron-containing impurities are difficult to clean in a concentrated mode are solved. According to the technical scheme, the pickling device for quartz sand production comprises a supporting frame, a first tank body and the like; a first tank body for containing quartz sand to react with an acid solution is mounted on the support frame. According to the device, the quartz sand dispersing effect of the separator is improved in the quartz sand feeding process through the separation blocks on the separator, the quartz sand is prevented from being stacked and caked, and the picklin
