Description

Technical Field

[0001] The utility model relates to the technical field of polysilicon production equipment, in particular to a device for removing magnetic substances in silicon materials. Background Art

[0002] During the production and crushing process of silicon materials, high-strength crushing equipment is used to extrude and crush them into silicon materials of different particle sizes. Subsequently, they are divided into silicon materials of different particle sizes through screening and other processes. Although the crushing equipment is high in strength, magnetic substances such as iron filings will still be produced during the friction process. This part of magnetic substances is mainly concentrated in silicon materials below 3mm. However, this part of powder material not only has high surface metal content but may also affect product quality during downstream use.

[0003] At present, the removal of magnetic materials in silicon materials with small particle sizes is generally done by metal detectors. However, since the magnetic materials detected by metal detectors have large particle sizes and need to be manually sorted after detection, the current equipment is mainly suitable for post-event prevention. Sorting out magnetic materials with large particle sizes not only affects production efficiency, but also poses a risk of secondary contamination of silicon materials after detection. In addition, it is difficult to remove magnetic materials with small particle sizes.

[0004] The existing double-layer magnetic separator equipment uses a magnetic roller to absorb magnetic material and then rotates it to leave the magnetic force range of the magnetic roller. The magnetic material is then separated by the magnetic material's own gravity. The disadvantage is that the double-layer belt entering the magnetic separator needs to be spread by a vibrating feeder. If the material is thicker in this process, the magnetic material cannot be effectively removed. Scratches / static electricity will be generated on the belt during operation. Magnetic material will be enriched with small particles here, and will be released when a certain variable is reached. It will be mixed with silicon material and the material with high surface gold after mixing needs to be re-screened or even cleaned, which will cause secondary pollution of the silicon material and increase the cost of silicon material.
