Description

Technical Field

[0001] The utility model relates to a dust removal system. Background Art

[0002] During industrial production (e.g., non-ferrous metal die-casting requires grinding of the blank after it is formed), dust is generated, and the dust particles are uneven in size. If professional equipment is not used to treat it, the diffuse dust will cause serious harm to the operator and the environment. During grinding, the dust particles thrown out by centrifugal force will be suspended in the air. Under certain conditions, if there are too many accumulated dust particles, they will react with oxygen in the air to oxidize, thereby releasing a large amount of heat, generating high temperature and high pressure, which may cause dust explosion safety accidents in severe cases. In view of this, this invention is specially applied for. Utility Model Content
