Abstract

The invention discloses a novel crushing device for the production of high-purity silicon, which comprises a bracket, a drum is arranged above the bracket, a bearing is arranged on one side of the outer wall of the drum, a rotating shaft is inserted into the inner ring of the bearing, and a spiral blade is arranged on the outer wall of the rotating shaft. And one end of the rotating shaft is fixedly connected to the output shaft of the motor, the outer wall of the motor is sleeved with a first connecting piece, the right side of the first connecting piece is provided with a second connecting piece, the second connecting piece is fixedly connected to the drum, and the lower right side of the drum is provided with a There is a cooling device under the raw material outlet, and a crushing device is installed under the cooling device. The crushing device includes a casing. The inner cavity of the casing is provided with a crushing chamber. The cavities are all provided with rotors, the outer walls of the rotors are all provided with a number of hammers, and screens are provided between the rotors. The beneficial effect of the invention is that the crushing efficiency can be greatly improved, the equipment failure rate can be reduced, and the crushing cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a novel crushing device for high-purity silicon production. Background technique [0002] High-purity silicon material refers to silicon material with relatively high silicon content. This is the latest product classification in the silicon industry, including: high-purity quartz sand, high-purity quartz powder, sand mound, optical fiber silicon material, synthetic silicon materials, fine silicon materials and so on. The preparation of high-purity silicon generally firstly produces industrial silicon (crude silicon) from silica, then high-purity polysilicon, and finally pulls it into semiconductor material silicon single crystal. Its production process is as follows: After crushing the crude silicon, it is treated with hydrochloric acid, aqua regia, (HF+H2SO4) mixed acid in sequence, and finally washed with distilled water to neutrality, and the industrial crude silic...
