Powder recovery device for crushing polycrystalline silicon

Abstract

The invention relates to the technical field of polycrystalline silicon production, and discloses a powder recovery device for crushing polycrystalline silicon. The powder recovery device comprises abase, a motor is fixedly mounted at the top of the base, an output shaft of the motor is sleeved with a transmission wheel, a first bearing seat is fixedly mounted at the top of the base and located on the right side of the transmission wheel, an exhaust fan is fixedly mounted at the top of the base and located on the right side of the first bearing seat, a recycling box is fixedly mounted at thetop of the base and located on the right side of the exhaust fan, and a collecting hopper is fixedly mounted on the right side of the recycling box. According to the powder recovery device for crushing polycrystalline silicon, powder on polycrystalline silicon is blown into a dust removal bag in the recovery box through an air inlet hole, the effect of efficiently collecting the powder in a full-sealing mode is achieved, and therefore the situation that the polycrystalline silicon is polluted by external dust is prevented, the production quality of the polycrystalline silicon is improved, resource waste is reduced, and the effects of energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of polysilicon production, in particular to a powder recovery device for crushing polysilicon. Background technique [0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation. Photovoltaic is used It is defined as the direct conversion of ray energy. In practical applications, it usually refers to the conversion of solar energy into electrical energy, that is, solar photovoltaic. Its realization is mainly through the use of solar panels made of semiconductor materials such as silicon, and the use of light to generate direct current, such as Solar cells can be seen everywhere in our daily life. With the continuous development o...
