After gasify, heat-conducting work medium after gasification moves in the inner cavity of cored screw blade, and the heat-conducting work medium after gasification passes through hollow spiral shell
After the outside heat conduction and heat radiation of the side plate of vane piece, the heat-conducting work medium after gasification is condensed into liquid heat-conducting work medium, condensed liquid
Heat gasifies again after the heat-conducting work medium of body shape flows at the bottom plate of cored screw blade, and the thermally conductive heat exchange of thermal energy passes through thermally conductive work
The liquid-gas phase transition of matter carrys out thermally conductive heat exchange, and heat-conducting work medium carries out the thermally conductive heat exchange of liquid-gas phase transition in the inside of cored screw blade；
The thermal energy of cored screw blade is by heat transfer, heat radiation to the thermally conductive heating of material around cored screw blade.
The thermal energy that heat-conducting medium carries passes through the heat transfer of heat-conducting helical blade, heat radiation to the material around heat conducting pipe
Thermally conductive heating.
While the heat-conducting helical blade thermally conductive to material heating, can also play will in dry materials work
The effect that material is pushed ahead, stirred.
The workflow of heating, the drying of the material of conduction heating type dry vacuum container is as follows:
One, discharge gate is started, hopper, discharge gate, elbow, the roller that wet stock to be dried passes sequentially through feeding device are dry
The feed inlet in dry storehouse enters in roller drying storehouse.
Two, the thermal energy that heating device generates is conveyed by heat-conducting medium, and the thermal energy that heat-conducting medium carries directly passes through thermally conductive
The heat transfer of formula helical blade, heat radiation carry out thermally conductive heating to material around heat-conducting helical blade, in roller drying storehouse
Material has obtained the heating of thermal energy and has reached the material of necessary requirement water content standard after material carries out vacuum drying drying.
Three, in roller drying storehouse when dry materials, the moisture that the moisture vaporization in material generates is by exhaust pipe by peripheral hardware
Vacuum pump set pump drainage go out.
Four, material passes sequentially through the discharge port in roller drying storehouse, the elbow of discharge device, discharge gate, hopper after drying
Roller drying storehouse is discharged.
The present invention has the advantages that compared with existing roller drying storehouse: a kind of conduction heating type dry vacuum container
Heat-conducting helical blade can give the thermally conductive heating of material, can also play and push ahead material in dry materials work, stir
The effect mixed；Thermal energy is led by the heat transfer of heat-conducting helical blade, heat radiation to material around heat-conducting helical blade
Heat heating.Material continuously can ceaselessly pass in and out roller drying storehouse by feeding device and discharge device, and material can be connected
The vacuum drying of continuous property, the dry efficiency of improving material and optimization dry materials effect.Material is pushed away heat-conducting helical blade
Into must also obtain uniform stirring in whipping process, the drying uniform moisture degree of material is also improved.
