A polysilicon bagging metering control system

Abstract

The invention provides a polycrystalline silicon bagging metering control system. Crushed polycrystalline silicon block materials are at least screened into block materials of two specifications through a screening device. A first material conveying device is used for conveying the block materials of the large specification to a metering hopper, and a second material conveying device is used for conveying the block materials of the small specification to the metering hopper. According to the weight of the large-specification block materials stored in the metering hopper at present, the first material conveying device is controlled to stop, and the second material conveying device is controlled to start. According to the total weight of the large-specification block materials stored in the metering hopper at present and the small-specification block materials stored in the metering hopper at present, the second material conveying device is controlled to stop, and manual participation is not needed in the whole process. Automatic polycrystalline silicon bagging metering is achieved, it is guaranteed that the weight of single bags of polycrystalline silicon products can be in high precision, the manual workload is reduced, the labor intensity is lowered, and labor cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of polysilicon packaging, in particular to a polysilicon bag [0002] Metering control system. Background technique [0003] After the production of polysilicon is completed, the obtained polysilicon products have large specifications, and the size and specification are quite different, which cannot meet the requirements of finished product packaging. Therefore, further crushing is required to break into smaller-sized lumps, and then through vibratory screening to distinguish different sizes of lumps, and finally put the crushed and screened lumps into packaging bags, and put each The weight of the polysilicon product in the bag is controlled at a preset weight. [0004] The traditional process of polysilicon bagging and weighing has not been fully automated, and semi-automatic equipment is used in the packaging, weighing and weighing processes, that is, through automatic crushing and vibrating screening o...
