Description

Technical Field

[0001] This utility model relates to the field of silicon material screening technology, and in particular to a silicon material screening device with an inclined vibrating disc. Background Technology

[0002] Silicon, as a core raw material for the photovoltaic and semiconductor high-tech industries, is widely used in energy conversion and electronic information fields and is an important cornerstone for promoting the development of related industries. However, the purity difference and particle size inconsistency of silicon are common problems. This not only affects the performance and quality stability of silicon products, but may also cause resource waste and economic losses. In the process of mining, processing and transportation, silicon wafers in photovoltaic module production and silicon materials in semiconductor chip manufacturing are easily mixed with impurities and form particles of different sizes, resulting in reduced conversion efficiency and unstable performance of subsequent products.

[0003] During the mining process, silicon material is formed into particles of different sizes, which need to be screened using vibrating motors and filters. Traditional screening devices have a high vibration intensity, which may cause the silicon material to collide violently on the screen surface, resulting in the breakage of some particles and the generation of ultrafine dust and unqualified fragments. Existing screening devices use inclined vibrating discs to reduce the problem of particle breakage, but they also have certain limitations. Long-term use can easily lead to local wear, and the installation and replacement of disc screens require high precision, which increases maintenance time. Utility Model Content
