When thermally conductive to material in the dryness storehouse dryer section heating of the thermal energy that heat-conducting medium carries in heating cabinet, there are A, B two Mode carries out thermally conductive heating to material: A, the thermal energy that heat-conducting medium carries in heating cabinet is carried out by the warehouse of dryness storehouse to material Thermal conductivity heating.
B, the thermal energy that heat-conducting medium carries in heating cabinet passes through the metal tube of heat pipe condenser section, the heat transfer of fin, hot spoke The material penetrated around the heat pipe to the dryer section of dryness storehouse carries out thermal conductivity heating, and the material for obtaining thermal energy carries out dry baking It is dry, reach the material of necessary requirement water content standard.
The thermal energy of high-temperature material at the cooling section of the dryness storehouse in roller drying storehouse by the warehouse and heat pipe of dryness storehouse come Heat conduction and heat radiation is cooling.
1, the thermal energy conduction of the material high temperature after drying is to the material high temperature on the warehouse at dryness storehouse cooling section, after drying Thermal energy by hot pipe conducting to the low temperature heat-conducting medium pair on the warehouse at dryness storehouse cooling section, in the cooling storehouse outside dryness storehouse The warehouse of dryness storehouse cooling section is cooled down, and the material after drying can radiate to have obtained cooling.
2, the thermal energy of the material high temperature after drying is evaporated by heat transfer, thermal energy conduction to the heat pipe at dryness storehouse cooling section On heat-conducting work medium in the heat pipe of section, heat pipe is rotated with dryness storehouse, and heat-conducting work medium passes thermal energy in the heat pipe of condensation end of heat pipe It leads on the warehouse of dryness storehouse cooling section, the low temperature heat-conducting medium in the cooling storehouse outside the cooling section of dryness storehouse is cooling to dryness storehouse The warehouse of section carries out thermally conductive cooling, and the high-temperature material after drying can radiate to have obtained cooling；The heat-conducting medium of low temperature obtains Become the heat-conducting medium of high temperature after energy heats, it can be with UTILIZATION OF VESIDUAL HEAT IN.
The energy consumption index for having the conductive drying of the rotary-drum vacuum dryer of cooling section is 2800-4000kj/kg, and convection current Dry is 4000-7500kj/kg；The thermal energy availability of convective drying generally only has 20-50%, and conductive drying is resonable By above can be close to 100%, the actually thermal energy availability in conductive drying formula vacuum dryer can achieve 60-80%, This is that have the conductive drying of the rotary-drum vacuum dryer of cooling section not need Hot-blast Heating material, by being vented lost thermal losses It is small.
Material is dry under the vacuum state in roller drying storehouse, and when material constant rate of drying reduces the boiling point of water, material The vaporization boiling temperature of middle moisture is reduced to 35 DEG C -60 DEG C from 100 DEG C, and material heating is minimum, and heat almost all is used to evaporate Hygroscopic water has the power savings advantages of the rotary-drum vacuum dryer of cooling section bigger, in this way when such as approaching or being less than critical moisture content The availability for improving thermal energy reduces the total amount consumed of thermal energy.
The present invention has the advantages that compared with existing dryer: a kind of rotary-drum vacuum dryer having cooling section The thermal energy of heating device is heated to dry materials by heat-conducting medium, is thermally conductive, and thermal conversion efficiency is high and loss is small, improves material Rate of drying.During drying material in vacuum, roller drying storehouse rotates under the action of driving device, helical blade and heat pipe Has the function of stirring and propulsion, drying materials do not have dead angle, material prevented from caking, material when the dryer section of dryness storehouse is dry Dries quantity is uniform, and the material after drying is cooled down in cooling section, improving material drying efficiency and optimization dry materials effect. The thermal energy that material releases when cooling can be with UTILIZATION OF VESIDUAL HEAT IN；Leakage is generated when damage occurs in a certain heat pipe, that is, only It is that this root heat pipe can not work, does not influence the use for the rotary-drum vacuum dryer for entirely having cooling section.
