Description

Technical Field

[0001] The utility model relates to the technical field of fan rotors, in particular to a fan rotor blade disassembly and fixing device. Background Art

[0002] A boiler induced draft fan is a device that relies on the mechanical energy input from an electric motor to increase gas pressure and discharge gas. It is usually used as a driven fluid machine. The boiler induced draft fan generates negative pressure through its rotating impeller, extracts flue gas from the boiler, and pushes it axially to the exhaust system such as the desulfurization island or chimney. Its working principle is similar to that of a turbine compressor, but because the gas flow rate involved is low and the pressure change is not large, the gas is usually treated as an incompressible fluid for processing.

[0003] The blades of the boiler induced draft fan of a thermal power unit need to be regularly inspected and maintained to ensure their performance and life, so the blades need to be disassembled and installed.

[0004] However, when most existing wind turbine rotor blades are disassembled one by one, the force is uneven, and the wind turbine rotor rotates autonomously, thus causing safety hazards. Utility Model Content
