Polycrystalline silicon block material crusher

Abstract

The invention discloses a polycrystalline silicon block material crusher, and belongs to the field of polycrystalline silicon production. The polycrystalline silicon block material crusher comprises abox body and a screen mesh arranged in the box body; a fine material collecting hopper positioned at the lower end of the screen mesh and a coarse material collecting hopper butted with the output end of the screen mesh are also arranged in the box body; and packaging mechanisms are mounted below the fine collecting hopper and the coarse collecting hopper. According to the polycrystalline siliconblock material crusher, the crushing efficiency of a finished polycrystalline silicon product is enhanced, the use of equipment is reduced, the whole crushing process is simpler, the exposure time ofthe silicon material in the outside is shortened, the silicon material is effectively prevented from being polluted in the crushing process, and the purity of the final polycrystalline silicon blockmaterial is greatly improved.

Description

technical field [0001] The invention belongs to the field of polysilicon production, and in particular relates to a polysilicon block breaker. Background technique [0002] The finished polysilicon product is a cylindrical product. According to customer needs, it needs to be broken into bars and blocks of different specifications and sizes, and then packed into bags. Finally, it is boxed and palletized and sent to customers. This process requires extremely high purity of the product. [0003] At present, polysilicon products are generally crushed by manual or artificially assisted machinery. In this process, not only non-silicon impurities and micro-silicon powder may be introduced, but also some materials will splash out and fall to the ground during the crushing process, so that the polysilicon products will be crushed after crushing. Manual sorting, purging or cleaning is required again, which not only makes the crushing process of polycrystalline silicon products more cu...

Problems solved by technology

[0003] At present, polysilicon products are generally crushed by manual or artificially assisted machinery. In this process, not only non-silicon impurities and micro-silicon powder may be introduced, but also some materials will splash out and fall to the ground during the crushing process, so that the polysilicon products will be crushed after crushing. Manual sorting, purging or cleaning methods are required again, which not only makes the crushing process of polycrystalline silicon products more cumbersome, but also increases equipment costs and reduces crushing efficiency
