Three, when heated type lifting blade is in up/down state, the gasiform heat-conducting work medium for releasing thermal energy is condensed into liquid The heat-conducting work medium of shape is at the bottom plate that the side plate of heated type lifting blade flows to heated type lifting blade, at heated type lifting blade bottom plate Liquid heat-conducting work medium by the energy heats in the external heating tank of warehouse the heat-conducting work medium of phase-changeable gas shape, it is thermally conductive Condensation that working medium loops back and forth like this, gasification, condensation, gasification.

The roller drying storehouse is rotary motion on support roller, and heating tank is fixed.

The workflow for heating heating, the drying of the material of the board-like rotary-drum vacuum dryer of lifting is as follows:

One, start driving device, under driving device induced effect, roller drying storehouse rotates on support roller in roller drying storehouse Movement.

Two, after starting wind stopping device, wet stock to be dried passes sequentially through the hopper of feeding device, wind stopping device, and bellows is curved Head, the feed inlet in roller drying storehouse enter in roller drying storehouse.The rotation of material in roller drying storehouse in heated type lifting blade Under progradation, discharge outlet flow progresses of the material from the feed inlet in roller drying storehouse to roller drying storehouse.

Three, after the heating devices heat that heat-conducting medium passes through peripheral hardware, the thermal energy that heat-conducting medium carries directly passes through heated type The heat transfer of lifting blade, heat radiation carry out thermally conductive heating to material around heated type lifting blade, and the material in roller drying storehouse obtains The thermally conductive heating of thermal energy is arrived.

Four, the moisture that the moisture vaporization in roller drying storehouse when dry materials in material generates is by exhaust pipe by vacuum machine Group pump drainage is gone out, and after material carries out vacuum drying drying, reaches the material of necessary requirement water content standard.

Five, driving device sets different revolving speeds by the program of setting according to controller to drive roller drying storehouse Rotation, material passes sequentially through the discharge port in roller drying storehouse, the bellows elbow of discharge device, wind stopping device discharge roller after drying Dryness storehouse.

The vacuum conductive drying energy consumption index for heating the board-like rotary-drum vacuum dryer of lifting is 2800-3500 kilojoule per kilogram Water, and convective drying is 5500-8500 kilojoule per kilogram of water；The thermal energy availability of convective drying generally 20-50%, and Vacuum conductive drying theoretically can be close to 100%, this is because the vacuum conduction of the heating board-like rotary-drum vacuum dryer of lifting Drying does not need Hot-blast Heating material, small by the thermal losses for being vented lost.The rotary-drum vacuum dryness storehouse of interior heating is in constant rate of drying Section, because vacuum or decompression reduce the boiling point of water, material heating is minimum, and heat almost all is used to evaporate hygroscopic water, such as close Or when being less than critical moisture content, the power savings advantages for heating the vacuum conductive drying of the board-like rotary-drum vacuum dryer of lifting are got over Greatly.

The utility model has the advantages that compared with existing rotary-drum vacuum dryer: a kind of board-like rolling of heating lifting The heat conduction and heat radiation of cylinder vacuum dryer is that heated type lifting blade exchanges heat to the solid in storehouse, and the thermal energy that heat-conducting medium carries passes through warehouse To the thermally conductive heating of heat-conducting work medium in heated type lifting blade, heated type lifting blade will be around thermal energy conduction to heated type lifting blade On material.The thermally conductive heating speed of thermal energy is improved, bellows elbow allows the work shift of generation under rated load effect, The fixed seal connection between the wind stopping device and bump joint in the rotary course of roller drying storehouse is ensured.Driving device is according to control Device processed sets different revolving speeds by the program of setting to drive the rotation in roller drying storehouse.Material is in heated type lifting blade Uniform stirring must also have been obtained by promoting in whipping process, and the drying uniform moisture degree of material is also improved.Add when a certain There is damage to storehouse and generates leakage in hot type lifting blade, does not influence the use in entire roller drying storehouse, and it is board-like to reduce heating lifting The failure rate of rotary-drum vacuum dryer improves the service life of the heating board-like rotary-drum vacuum dryer of lifting.
