Description

Technical Field

[0001] This utility model relates to the field of silicon material screening technology, and in particular to an adjustable-gap mesh belt screening device for silicon material screening. Background Technology

[0002] As a crucial basic material, the demand for silicon is constantly increasing, and the requirements for its quality and particle size distribution are becoming increasingly stringent. Different applications require silicon with specific particle size ranges. Silicon used in semiconductor manufacturing requires more uniform and precise particle size to meet the needs of high-precision chip manufacturing. In the photovoltaic field, although the requirements for silicon particle size are relatively relaxed, a certain particle size distribution still needs to be ensured to improve the conversion efficiency and stability of solar cells. Traditional screening equipment is difficult to meet the silicon industry's requirements for high-precision and high-efficiency screening. Therefore, it is necessary to develop new screening equipment to adapt to the development of the silicon industry.

[0003] Traditional silicon material screening equipment has many drawbacks. The equipment has poor sealing, and impurities are easily mixed in during the screening process, which seriously affects the purity of silicon material and product quality. Some equipment also has low screening efficiency, making it difficult to meet the needs of large-scale production. Existing equipment uses mesh belt conveyors and automated control systems to realize continuous feeding, screening and discharging of silicon material, reducing manual intervention and improving production efficiency. At the same time, it also reduces the errors and uncertainties caused by manual operation and can be used for large-scale production. However, it lacks flexibility when processing silicon material of different particle sizes, cannot accurately control the screening process, and cannot flexibly adjust the mesh belt spacing to adapt to the screening of silicon material of different particle sizes. Therefore, it does not meet the needs of users. Utility Model Content
