Description

Technical Field

[0001] The utility model relates to the field of dust collectors, in particular to an external filtering pulse dust blowing bag dust collector. Background Art

[0002] When the dust collector is working normally, the dust-containing gas enters the ash hopper from the air inlet. Due to the rapid expansion of the gas volume, some coarser dust particles fall into the ash hopper due to inertia or natural sedimentation, and most of the remaining dust particles rise with the air flow and enter the bag chamber. After being filtered by the filter bag, the dust particles are retained on the outside of the filter bag. The purified gas enters the upper box from the inside of the filter bag and is discharged into the atmosphere from the exhaust port, thereby achieving the purpose of dust removal.

[0003] As the filtration continues, a large amount of dust will adhere to the outside of the filter bag. After searching, a pulse bag dust collector disclosed in announcement No. CN219502236U is mainly opened by an electromagnetic pulse valve, and the compressed gas in the air bag connected to the blowing pipe is sprayed into the bag through the venturi tube. The dust adsorbed on the bag falls under the impact of the airflow, thereby completing pulse cleaning and achieving the purpose of cleaning. However, when the dust adhered to the surface of the filter bag is relatively firm, the high-pressure gas will flow out through other positions of the filter bag, and the firmly attached dust will remain on the filter bag, affecting the filtration of the filter bag.

[0004] Therefore, we propose an external filtering pulse blowing bag dust collector to solve the above problems. Utility Model Content
