Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to an easily disassembled fan device for a boiler. Background Art

[0002] In the use of boilers now, in order to improve work efficiency, ventilators are often used to increase the air supply for filtration, and centrifugal ventilators are relatively long-term used. Centrifugal fans rely on input mechanical energy to increase gas pressure and deliver gas in parallel. The principle of centrifugal fans is based on the principle of converting kinetic energy into potential energy. The gas is accelerated by a high-speed rotating impeller to convert kinetic energy into potential energy. When the centrifugal fan is running, the continuous rotation of the impeller will cause the fan to vibrate as a whole, especially the outer casing, which has a large degree of vibration. When used for a long time, various connection points will become loose, resulting in unstable operation, and strong noise will be generated due to the vibration, which brings great inconvenience to use. In addition, due to the vibration of the centrifuge, the air supply pipeline will vibrate, which is prone to air leakage, which has a great impact on later maintenance. For the above problems, there may already be technical means to solve them in the prior art, but this case intends to provide an alternative or replacement technical solution. Utility Model Content
