Polysilicon crushing device

Abstract

The invention discloses a polysilicon crushing device and relates to a polysilicon crushing appliance. An upright post (13) is arranged at the middle part of any side of a material box (12), a rotating shaft (14) is movably connected with the upper part of the upright post in an inserting manner, one end of a guide rail (3) is fixedly connected with the upper end of the rotating shaft (14) or one end of the guide rail is movably connected with the upper end of the upright post so as to form a horizontal rotating structure of the guide rail, a sliding mechanism is in sliding fit with the guide rail, an elastic body connected with an impact cylinder (17) is arranged at the lower part of the sliding mechanism, and an impact head (18) is arranged at the lower end of the impact cylinder so as to form a structure enabling the impact head to be in multi-station correspondence with polysilicon (6) in the material box (12). In the invention, an extension spring arranged on the guide rail is used to flexibly control a silicon rod beating structure consisting of the impact cylinder and the impact head, thereby effectively overcoming the defects of manual crushing, such as high cost, low efficiency, unsafety and the like, effectively improving the production efficiency and achieving the purpose of mechanical crushing.

Description

【Technical field】 [0001] The invention relates to a polysilicon crushing device, in particular to a polysilicon crushing device. 【Background technique】 [0002] As we all know, polysilicon is an extremely important link in the silicon industry chain. It is one of the basic materials in artificial intelligence, automatic control, information processing, photoelectric conversion and semiconductor industries. Especially with people's pursuit of green energy, polysilicon As the most important basic material of silicon-based solar cells, it is used in a huge amount; in the preparation method of polysilicon, especially in the improved Siemens method, metallurgical silicon powder and hydrogen chloride generate trichlorohydrogen under certain temperature and pressure conditions The mixture of silicon and hydrogen is used for reduction in the reduction furnace. Before the reduction in the reduction furnace, the polysilicon is first crushed into pieces of a certain size, and then put ...
