Technical Field

[0001] The utility model relates to the technical field of mesh belt dehydrogenation furnaces, in particular to an air guide device for a mesh belt dehydrogenation furnace. Background Art

[0002] Since the standard parts absorb hydrogen after electroplating, the workpiece will suffer from hydrogen embrittlement and be easy to break. Therefore, it is necessary to carry out a dehydrogenation process and keep the hydrogen in the workpiece at about 200°C for a certain period of time to remove the hydrogen absorption in the workpiece and eliminate the hydrogen embrittlement. Most of the processing is carried out through a mesh belt dehydrogenation furnace.

[0003] In order to ensure uniform temperature inside the furnace, the traditional practice is to install a single circulation fan on the top of the furnace to blow and stir the furnace, thereby speeding up the flow of internal hot air flow and facilitating internal uniform temperature control. However, in actual use, this method takes a long time to achieve uniform temperature control in the furnace due to the influence of the volume of the furnace and the number of mesh belts, which seriously affects processing and use.
