Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand processing, in particular to a purification reaction device for high-purity quartz sand. Background Art

[0002] Quartz sand is a hard, wear-resistant and chemically stable silicate mineral, which is an important industrial mineral raw material and is widely used in industries such as ferrosilicon smelting, metallurgical flux, metallurgy, construction, and chemical industry. During the production process of quartz sand, other impurities are often mixed in the quartz sand and need to be removed and purified. Generally, acid washing is used for impurity removal and purification. However, it is rather troublesome to separate the quartz sand from the acid solution after acid washing and impurity removal. The existing separation method is to first pump out the acid solution and then discharge the quartz sand, with low efficiency. In addition, there is still a large amount of acid solution in the quartz sand that sinks to the bottom, and the acid solution cannot be drained completely. When discharging, a large amount of acid solution is carried, which is rather wasteful. Summary of the Utility Model

[0003] In view of the above situation, to make up for the above-mentioned existing defects, the utility model provides a purification reaction device for high-purity quartz sand that can separate quartz sand from acid solution and is convenient for discharging materials.

[0006] In order to enable the acid solution to react with the quartz sand for high-efficiency purification, the reaction stirring structure includes a driving motor, a stirring shaft, and a stirring assembly. A driving chamber is provided at the top of the reaction tank. The driving motor is arranged on the inner side wall of the driving chamber. The upper connecting pipe penetrates through the reaction tank and is rotatably arranged inside the driving chamber. The upper end of the stirring shaft is rotatably arranged on the inner top wall of the driving chamber, and the lower end of the stirring shaft penetrates through the upper connecting pipe and the purification tank and is rotatably arranged inside the discharging pipe.

Driven bevel gears are respectively arranged at the top of the stirring shaft and the top of the upper connecting pipe. The driving bevel gear meshes with the driven bevel gears respectively. The stirring assembly is arranged on the stirring shaft and is located inside the purification tank.

[0007] Further, the stirring assembly includes a support frame, stirring rods, and a scraper. A spiral stirring blade is provided on the stirring shaft. The support frame is provided on the stirring shaft. The stirring rods are arranged on the support frame in the height direction.

[0010] For a purification reaction device for high-purity quartz sand proposed by the present utility model, the beneficial effects obtained by adopting the above structure are as follows:

[0011] A purification tank is arranged inside the reaction tank, so that the quartz sand and the acid solution are always separated, and the acid solution can enter the inside of the purification tank through the filter screen; through the cooperation of the drive motor, the stirring shaft, and the stirring assembly, the quartz sand inside the purification tank can be fully stirred and mixed with the acid solution. At the same time, the purification tank rotates in the opposite direction to the stirring direction, increasing the stirring efficiency. The provided scraper prevents the quartz sand from blocking the filter screen. When discharging materials, the acid solution is discharged first, and the quartz sand can filter out the acid solution through the filter screens provided at the bottom and the side walls, reducing the loss of the acid solution; through the provided spiral stirring blade, it can assist in turning the quartz sand at different depths to react with the acid solution, preventing precipitation from affecting the sufficiency of the reaction, and at the same time assisting the discharge of the quartz sand when the drive motor rotates in the reverse direction.
