Description

Technical Field

[0001] The present disclosure relates to the technical field of air handling, and in particular to a spoke of a rotor and a rotor for an air handling machine. Background Art

[0002] This section provides background information related to the present application which does not necessarily constitute prior art.

[0003] At present, air handling machines such as rotary dehumidifiers and rotary heat recovery machines commonly used in the field of air handling technology all have a rotary wheel with spokes on it. The spokes divide the rotary wheel into multiple areas with different functions and have a certain strength to carry the dehumidification material / heat recovery material, etc. in the rotary wheel.

[0004] Since the rotor generally operates in a high temperature and high humidity environment, the spokes need to have good anti-corrosion performance. Existing spokes are generally formed by bending steel plates, and the bent profile plates are spliced ​​and welded together, and galvanized to achieve the purpose of corrosion protection. The manufacturing process of this type of spoke is complicated and costly. The overall strength of the spoke is greatly affected by the welding process. In addition, due to the limited anti-corrosion ability of the galvanizing process, the corrosion resistance of the product is insufficient, which further reduces the strength of the spokes. At the same time, it reduces the service life of the product and increases the maintenance cost of the equipment. Utility Model Content
