Background
The centrifugal fan is a machine which increases gas pressure and discharges gas by means of input mechanical energy, and is widely applied to industries such as power plants, mines and the like. The centrifugal fan accelerates gas by using an impeller rotating at a high speed according to the principle that kinetic energy is converted into potential energy, and then decelerates and changes the flow direction so as to convert the kinetic energy into the potential energy (pressure). In a single stage centrifugal fan, the gas enters the impeller from an axial direction, changes to a radial direction as it flows through the impeller, and then enters the diffuser. In diffusers, the gas changes flow direction and the increase in conduit cross-sectional area slows the gas flow, which converts kinetic energy into pressure energy. The pressure increase occurs primarily in the impeller and secondarily in the diffusion process. In a multistage centrifugal fan, a flow reverser is used to direct the air flow to the next impeller, creating a higher pressure.
However, the existing centrifugal fan impeller is inconvenient to mount and dismount, and cannot prevent solid particles in outside air from entering the impeller to cause damage to the impeller; therefore, the existing use requirements are not satisfied.
