Description

Technical Field

[0001] The present invention relates to the technical field of paint drying ovens, and in particular to a drying oven structure. Background Art

[0002] After the copper wire is painted, it needs to be heated and baked. Currently, this baking process is performed in a copper wire drying oven. The air in the oven is heated by heating tubes in the oven, thereby baking the copper wire passing through the oven. Currently, the copper wire drying oven can bake multiple copper wires at the same time, but when there are fewer copper wires to be baked, the heating tubes are still fully open, so that the energy used to bake all the copper wires is the same as that of a small number of copper wires, resulting in a waste of production resources.

[0003] After searching, the applicant found that the Chinese patent document with application number 201110203875.8 disclosed a method for baking an industrial furnace module and a baking device thereof on November 21, 2012, which includes an industrial furnace module, the industrial furnace module including two industrial furnace module side walls, an elbow box for connecting the two industrial furnace module side walls, and a furnace base and a furnace top smoke hood sealed with the industrial furnace module side walls; thermocouple sockets are respectively provided on the furnace top smoke hood, the sealed furnace base, the industrial furnace module side wall or the elbow box, and thermocouples for monitoring temperature are installed in the thermocouple sockets; an electric heating component connected to an electric heating control program is provided in the industrial furnace module, and an insulation layer is respectively provided on the furnace base and the furnace top smoke hood; holes or slits for dehumidification are distributed on the industrial furnace module side walls, the elbow box and the furnace top smoke hood; this device also cannot solve the above-mentioned technical problems.
