Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polysilicon production equipment, in particular to a feeding device for rod-shaped polysilicon. Background Art
[0002] Polycrystalline silicon is a form of elemental silicon. When molten elemental silicon solidifies under supercooling conditions, silicon atoms are arranged in the form of diamond lattices to form many crystal nuclei. If these crystal nuclei grow into grains with different crystal plane orientations, these grains will combine to crystallize into polycrystalline silicon.
[0003] During the production, crushing and packaging of polysilicon, in the prior art, the crushing and processing of rod-shaped polysilicon is mostly done by manual selection and manual loading. However, during the selection and loading process, due to the large size and weight of the silicon rods, the surface silica ash is difficult to clean, resulting in a layer of silica ash often adhering to the surface of the silicon blocks. The silica ash is easily moved with the loading, and then diffuses and pollutes the surrounding environment. In addition, due to the lack of strength of the loading personnel and the difficulty in grasping, the silicon rods often come into contact with the clothing and gloves of the loading personnel, resulting in an increase in the surface metal of the silicon rods, which in turn affects the quality of the polysilicon.
