Problems solved by technology
The convective heating method of the gas-fired hot air disturbs the air in the drying tunnel, which inevitably leads to a certain degree of powder flying and falling of the powder parts before melting. The powder flying and falling affect the thickness of the solidified powder of the finished parts, resulting Preservative quality and sensory quality issues
At the same time, dusting and falling powder not only cause waste of powder, but also lead to potential safety hazards
[0003] For the problems in related technologies, no effective solutions have been proposed yet

The invention relates to gas radiation heating device for powder coating process drying and curing. The gas radiation heating device for the powder coating process drying and curing comprises a plurality of heat radiation tubes arranged oppositely and in parallel, wherein one ends of the heat radiation tubes are connected through U-shaped return tubes, the other ends of heat radiation pipes are divided into connectors I and connectors II, the connectors I are connected with heat generators, the connectors II are connected with a collecting and conveying device through connecting pieces, an exhaust pipe is connected above the collecting and conveying device, a negative-pressure fan is arranged at the tail end of the exhaust pipe, the upper part and lower part and the outer sides of the heat radiation tubes are all provided with directional reflection plates, the directional reflection plates are fixed on a cross support, the cross support is fixed on a vertical steel frame, the vertical steel frame is fixed on a shaping structure, and the inner side of the shaping structure is connected with the directional reflection plates; and a heat preservation system is arranged between the directional reflection plates and a device shell, and the linkage heat supply process of the heat radiation tubes, the heat generators and the negative pressure fan is controlled by a temperature control cabinet. The gas radiation heating device has the advantages that the phenomena of powder raising and powder falling can be avoided.
Description
technical field [0001] The invention relates to the field of drying and curing heating in the powder coating process, in particular to a gas radiation heating device for drying and curing in the powder coating process. Background technique [0002] At present, the powder coating process of home appliances, furniture, automobiles, etc. in our country is dried and solidified. Generally, the burner body is used to burn natural gas or propane gas to generate flame and smoke, and then the hot air of the burning flue gas is transported directly or through the hot air of heat exchange. In the drying tunnel, the components are dried and heated by means of convection heating, so that the powder coating process undergoes melting, leveling, gelling, and curing processes. The convective heating method of the gas-fired hot air disturbs the air in the drying tunnel, which inevitably leads to a certain degree of powder flying and falling of the powder parts before melting. The powder flyin...
