AI Technical Summary
Technical Problem
Existing centrifugal fan impellers are prone to dust accumulation during operation, leading to increased vibration and reduced safety. Furthermore, existing dust removal structures cannot effectively remove dust from the back of the blades.
Method used
An axial turbulence tube and a radial nozzle are installed on the back of the blade. High-pressure gas is ejected through these structures to generate turbulence and remove dust, thus achieving automatic dust removal.
Benefits of technology
It effectively reduces impeller dust accumulation, lowers downtime frequency, improves fan operation safety, extends impeller life, saves energy, and reduces enterprise costs.

Abstract
The application discloses a novel automatic full-dust-cleaning impeller, which comprises a front disc, a middle disc and a plurality of blades which are arranged in a circumferential direction and are arranged between the front disc and the middle disc, a hub assembly is arranged in the middle of the middle disc, a plurality of axial spoiler pipes are arranged in a radial direction on the back of each blade, a plurality of radial nozzles which are used for spraying against the back of the blade are arranged in an axial direction on the side of each axial spoiler pipe which faces the outer periphery of the impeller, a plurality of radial air inlet pipes are arranged on the inner surface of the front disc, each blade corresponds to a radial air inlet pipe, each radial air inlet pipe and the plurality of axial spoiler pipes on the blade corresponding to the radial air inlet pipe are in communication, each radial air inlet pipe has a high-pressure air inlet which extends out of the outer surface of the front disc, a plurality of axial nozzles which are used for spraying against the joint of the axial spoiler pipe and the back of the blade are arranged in a radial direction on each radial air inlet pipe, and high-pressure gas which enters the high-pressure air inlet is sprayed out through the axial nozzles and the radial nozzles.
