Description

Technical Field

[0002] Scrap steel refers to the steel waste (such as trimmings, ends, etc.) that does not become products in the production process of steel mills, as well as the steel materials in equipment and components that are scrapped after use. Scrap steel is made of steel, and scrap steel is made of pig iron. They are collectively called scrap steel.

[0003] After being crushed by a crusher, scrap steel becomes scrap steel material of a certain size. The scrap steel material needs to be transferred from the crusher to a conveyor belt. The existing patent application number is CN202022589184.3, which discloses a dust removal device for a scrap steel crushing production line. The dust on the production line is sucked away by the output end of a vacuum cleaner. However, during the transportation of scrap steel material to the discharge port of the conveyor belt, dust and noise are easily generated. The use of a vacuum cleaner cannot effectively absorb the dust at the discharge port and cannot achieve the purpose of noise reduction.
