Description
Technical Field
The utility model relates to a resin adhesive sealing hot air device.
Background
The conventional resin glue sealing and heating device adopts a simple heat tracing belt structure, and heat transfer is realized through the outer surface of the sleeve which is bound between the junction box of the heating tube bundle and the tube plate. However, due to physical properties and design limitations, the heat tracing band adopted by the seal adhesive heating structure can only be fixed on the outer wall of the outer ring sleeve of the heating tube bundle, and cannot be directly contacted with the inner ring sleeve inside the tube bundle.
Because of the inherent gaps among the heating pipes of each circle, the heat conduction efficiency of the heat tracing belt is relatively low, and the heating temperature difference of the heating pipes of the inner and outer circles is large, the temperature of the pipe orifice of the heating pipe of the outer circle can possibly meet the temperature requirement of the sealing glue, but the temperature of the pipe orifices of other heating pipes is far from reaching the standard.
In order to achieve a uniform heating up of each turn of heating pipe, one possible solution is to bind the heat tracing band to the outer wall of each turn of heating pipe. However, this solution results in a significant increase in manufacturing costs, since the gap per turn is limited, which increases the difficulty of binding the heat tracing band, with a corresponding increase in the labor and time required. In addition, heat transfer occurs between the heat tracing bands, so that internal heat accumulation cannot be effectively dissipated, and overheating damage of the heat tracing bands can be caused, thereby shortening the service life of the heat tracing bands.
Heat inside the tube bundle may be high due to heat build-up, resulting in uneven heating of portions of the tube orifices. As a result, the temperature of one part of the nozzle is too high, which leads to thermal degradation of the sealant layer, while the temperature of the other part of the nozzle is too low, which may lead to uneven application of the sealant, which directly affects the effect of the sealant. The problem brought by this is that the whole sealing effect declines, further influences the insulating properties of heating pipe to probably cause the waste of energy.
