Description
Technical Field
The utility model relates to an energy-saving fan impeller, and belongs to the technical field of fans.
Background
The centrifugal fan is an important process device for providing gas power in industrial production, and has extremely wide application in a plurality of important industries such as steel, cement, electric power, coal mine, petrifaction, waste gas and sewage treatment and the like. The working principle of the centrifugal fan is that gas is sucked in through the central part of an impeller of the centrifugal fan under the action of centrifugal force, and then flows into the space between blades, so that the gas flows out. But is influenced by factors such as imperfect structure, manufacturing process and design theory, the operation efficiency of the fan is not ideal, the actual consumed electric energy is overlarge, and economic loss is brought to related industrial production industries.
The traditional centrifugal fan impeller adopts a shaft disc riveting mode, after airflow enters the impeller, the airflow turns at an angle of almost 90 degrees, so that the efficiency of the fan is reduced, and the noise is increased; in addition, when dirt is formed on the surface of a blade to cause the impeller to be unbalanced, the rivet connection position of the rear disc can quickly generate cracks to cause the impeller to fail in the traditional stainless steel impeller with the riveting structure.
