Description

Technical Field

[0002] A dust collector is a device used to remove suspended particles in the air. It is widely used in air pollution control in industrial production processes and to improve indoor and atmospheric air quality. The dust collector fan can generate airflow, allowing the dust-laden gas to flow in the dust collector system.

[0003] After the dust collector fan completes the dust removal operation, a lot of dust, particles and other dirt will adhere to its impeller, which will cause the impeller to be in a state of unbalanced load. The unbalanced impeller will vibrate when rotating, which will cause loud noise. In addition, the presence of impeller dirt will increase the resistance to air flow, requiring greater power and energy consumption when the fan works, which will further increase the noise level. At present, most dust collector fans need to disassemble the impeller before taking it out for cleaning, and disassembling and installing the impeller requires additional workload and time, which will increase the time cost of maintenance and cleaning.
