Description

Technical Field

The utility model belongs to the technical field of dust filtering and processing, and in particular relates to a filter barrel type dust filter.

Background technique

Dust refers to dust particles. Dust particles are small and will float in the air or gather on the surface of objects. Dust-free operation is required in modern industrial production or various occasions. Therefore, filters are used to cooperate with fans to extract gas for filtration to achieve the effect of dust filtration.

When the existing dust filter is used for dust filtering, since the internal filter barrel structure is fixed, dust particles are easy to clog the mesh when the gas passes through for filtering. The clogged mesh will affect the smooth penetration of the gas, thereby affecting the filtering effect. The filter barrel needs to be frequently replaced and cleaned. For this reason, we propose a filter barrel type dust filter.
