Pickling device for stones

Abstract

The invention belongs to the technical field of stone impurity removal, and specifically discloses a pickling device for stones. The pickling device comprises a sand washing cylinder, an acid collecting tank and a motor; the acid collecting tank is communicated with the lower surface of the sand washing cylinder, and a valve is arranged at a connection part of the acid collecting tank and the sand washing cylinder; the sand washing cylinder is internally provided with an annular grid, and a sieving unit which comprises a filter layer, a separation layer and a support layer from top to bottom in sequence; a part, in the annular grid, of the filter layer is provided with mesh openings, a part, in the annular grid, of the support layer is provided with an opening; the separation layer is connected between the filter layer and the support layer in a sliding way, one end of the separation layer is connected with a spring which is fixed on the inner wall of the sand washing cylinder, and the other end of the separation layer is provided with a weighting block which is located on the outer wall of the sand washing cylinder; one side, near the spring, of the separation layer is provided with a through hole. After the pickling device is adopted, impurity removal and purification on the stones such as quartz sand can be realized, the quartz sand can be pickled with acids with different acid concentrations according to the quartz sand with different volumes, so that the degree of pickling can be effectively controlled and the pickling quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of stone material removal, and in particular relates to a stone pickling device. Background technique [0002] In modern life, stone is widely used in daily life. Stone needs to go through a series of processes from mining to final processing into products: mining-processing into blocks-finishing-quality inspection-finished products. [0003] Quartz stone is a kind of natural stone. It is a hard and chemically stable silicate mineral. It belongs to a non-metallic mineral. The main mineral component is SiO 2 . Quartz stone is an important industrial mineral raw material after being processed into quartz sand. It is a non-chemical dangerous product and is widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, Rubber, abrasive and other industries. Since iron, aluminum, phosphorus, titanium, potassiu...

AI Technical Summary

Problems solved by technology

Traditional impurity removal and purification have the following defects: 1. Soaking with acid solution is a static process, the speed of impurity removal is slow, and there are many impurities remaining in the quartz sand. This process cannot produce high-purity quartz sand; 2. Quartz sand The size of the particles is different. Use the same concentration of acid to soak the quartz sand of different specifications. The small quartz sand is easy to pickle excessively, while the large quartz sand is likely to be insufficiently removed; 3. Pickling-dehydration -Water washing needs to be carried out in different devices, and the efficiency of impurity removal is low
