Silicon material sorting and packaging production line

Abstract

The invention relates to the technical field of polycrystalline silicon, in particular to a silicon material sorting and packaging production line. The production line comprises a backflow device, a screening device, a plurality of material boxes and a packaging device; the backflow device comprises a plurality of rotary line bodies and straight line bodies; the rotary line bodies and the straightline bodies are connected end to end and form a loop; a plurality of material receiving section straight line bodies are arranged on the rear side of the rotary line bodies at a silicon material inlet end of the backflow device side by side; the screening device is arranged above the material receiving section straight line bodies; the plurality of material boxes are arranged on the backflow device; the packaging device is arranged on the rear side of silicon material discharging end line bodies of the backflow device; a sealing mechanism is arranged at the side of the packaging device; and the sealing mechanism comprises a heat sealing machine and a conveying belt mechanism. By means of the production line, the sizes of silicon materials can be controlled in the sorting and packaging process of the silicon materials, so that the silicon materials are prevented from being polluted by impurities such as metal and carbon, the working efficiency is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of polysilicon, in particular to a silicon material sorting and packaging production line. Background technique [0002] With the continuous development of the photovoltaic industry and the semiconductor industry, as the main application raw material for industry development, the demand for high-quality silicon materials in the market is increasing. The current silicon materials are mainly sorted manually, mostly mixed materials, with uneven particle size, difficult to control the fine powder rate of silicon materials, and low production efficiency. Therefore, in order to improve the quality and production efficiency of silicon materials, it is necessary to sort and pack the crushed silicon materials according to their sizes, so as to realize the clean production of silicon materials and meet the production needs of downstream enterprises.
