The tank body 30 of heat exchanger is exposed to distribute heat in air, cause the environment temperature of surrounding to rise, exist for a long time
It works, operator can be damaged in this environment, and waste thermal energy.Therefore, 30 outer surface of tank body of heat exchanger can
To be provided with thermal insulation layer, the heat that can avoid hot press leaks, it is possible to reduce heat distributes, and reduces environment temperature, improves scene
Operating environment, heat distribute less, play the role of save the cost.
Specifically, thermal insulation layer can be high temperature insulating cotton, or thermal isolation film can also be thermal insulation board.It needs to illustrate
, the structure of the thermal insulation layer of the utility model can be above-mentioned three kinds of structures, but be not limited solely to three kinds of structures, also
Can be other can satisfy the structure being thermally shielded to hot press.

In the hollow cavity of heating platen 3, and it is synchronous from conduction oil outlet circulation heat recovery exchanger, since conduction oil is always in heating platen 3
Hollow cavity and heat exchanger in recycle, it is ensured that the temperature of the conduction oil in hollow cavity be constantly in 115 DEG C of setting-
In 125 DEG C, therefore the conduction oil in the hollow cavity of heating platen 3 everywhere does not have the temperature difference, and the bulk temperature of heating platen 3 is balanced, guarantees
The quality of converted products, reduces rejection rate.But since conduction oil has the characteristic expanded with heat and contract with cold, and in 30 domestic demand of tank body
It is to be heated, the expansion of volume can be generated after heating, therefore the conduction oil of tank body 30 can not be filled it up with, but this will generate with
Under problem: conduction oil can react at high temperature with air, become sticky, can block conduction oil process each pipeline with
And the hollow cavity in heating platen, influence working effect, it is therefore desirable to periodic cleaning is carried out to pipeline and hollow cavity, and so not only
