The availability of the conduction heat exchange of energy is high.
The workflow of heating, the drying of the material of three dry vacuum containers of heating coil vane type is as follows:
One, airlock is started, material passes sequentially through feed hopper, airlock, the elbow of feeding device, the feed inlet of interior drying cylinder
Into in the storehouse of interior drying cylinder；Further, material is gone out under the impetus of helical blade by the inner cylinder of interior drying cylinder
In storehouse of the mouth by drying cylinder in middle cylinder import entrance；Further, material pass through under the impetus of helical blade in do
The middle cylinder outlet of dry cylinder is entered by outer cylinder import in the storehouse of outer drying cylinder.
Two, the thermal energy that heat-conducting medium carries carries out thermally conductive add to the material in three dryness storehouses by spiral heating device
Heat；Material in three dryness storehouses has obtained the heating of thermal energy and has reached necessary requirement after material carries out vacuum drying drying and contain
The material of water standard.
Three, the moisture that gasification generates when dry materials in three dryness storehouses is gone out by exhaust outlet by vacuum pump set pump drainage.
Four, material passes sequentially through going out for outer drying cylinder under the impetus of helical blade after the drying in three dryness storehouses
Three dryness storehouses are discharged in material mouth, elbow, the airlock of discharge device, discharging hopper.
The present invention has the advantages that compared with existing three dryness storehouses: a kind of three vacuum of heating coil vane type
The heat conduction and heat radiation that the thermal energy that the heat-conducting medium of dryness storehouse carries is conducted by spiral heating device to material, spiral heating dress
It replaces heat area and increases 8-30 times than the area of the cylinder of three dryness storehouses, the heat exchange area of spiral heating device accelerates
The thermally conductive heat exchange of thermal energy.It is without the use of extra hot-air when three dry vacuum container dried materials of heating coil vane type, therefore arranges
The heat loss that gas is taken away is negligible, and whole availability is 80%-90%, heating coil vane type three vacuum drying
The availability of the conduction heat exchange of the thermal energy in storehouse is high.Exhaust outlet moisture is discharged outside the storehouse of three dryness storehouses, spiral heating dress
Material when setting to drying is stirred propulsion, improves the drying uniformity of material, material can pass through feeding device and row
Expect that device continuously ceaselessly passes in and out three dryness storehouses, material can carry out successional vacuum drying, the dry effect of improving material
Rate and optimization dry materials effect.
