Due to heating device generate thermal energy be directly entered in the lifting heating apparatus in three dryness storehouses carry out it is thermally conductive Heat exchange, three dryness storehouses outsides do not need to install heating cabinet additional, and the structure of heating tank, three dryness storehouses is simple, low manufacture cost, dries The utilization rate in dry place is further improved.

Thermal energy entrained by heat-conducting medium is logical in the heat conducting pipe pipe of lifting heating apparatus in three dryness storehouses The concave shape bottom end that overheat is conducted to plate-type heat-pipe carries out thermally conductive heating；Thermal energy on bottom end is to liquid thermally conductive in heat pipe Working medium provides thermal energy, and thermal energy does not need secondary thermally conductive heat exchange, improves the thermal energy availability of thermal energy.

The energy consumption index of the conductive drying of three vacuum dryers of lifting blade heated type is 2800-4000kj/kg, and right Dry stream is 4000-7500kj/kg；The thermal energy availability of convective drying generally only has 20-50%, and conductive drying exists It theoretically can be close to 100%, the actually thermal energy availability in three vacuum dryers of lifting blade heated type can achieve 60—80%.Conductive drying is than convective drying energy conservation 30-50% under normal circumstances, this is because three vacuum of lifting blade heated type The conductive drying of dryer does not need Hot-blast Heating material, small by the thermal losses for being vented lost.

Material is dry under the vacuum state in three dryness storehouses, 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, when such as approaching or being less than critical moisture content, the power savings advantages of vacuum conductive drying are bigger, improve thermal energy in this way Availability reduces the total amount consumed of thermal energy.

After the inlet port and outlet port of three dryness storehouses are mounted with feeding device and discharge device, material by into Expect that device and discharge device continuously ceaselessly pass in and out three dryness storehouses, material can carry out successional vacuum drying, promote object Expect dry efficiency and optimization dry materials effect.

The vacuum drying workflow of the material of three vacuum dryers of lifting blade heated type is as follows:

One, wind stopping device, wind stopping device of the material by feeding device, bellows elbow, the feed inlet of three dryness storehouses are started Into in three dryness storehouses.

Two, after the heating devices heat that heat-conducting medium passes through peripheral hardware, the heat-conducting medium that carry thermal energy passes through heat conducting pipe Thermal energy import enters the inside of the heat conducting pipe of the lifting heating apparatus of three dryness storehouses, and thermal energy is directly heated by lifting blade and filled It sets to the thermally conductive heating of material around lifting heating apparatus.

Three, three dryness storehouses rotate under the induced effect of driving device, and online moisture tester will collect moisture letter Number being converted into electronic signal delivers into drive set controller, and drive set controller regulates and controls to drive by the program of setting The revolving speed of dynamic device, driving device set different revolving speeds by the program of setting according to drive set controller to drive three The rotation of cylinder dryness storehouse.

Four, it while thermally conductive to the material heating of lifting heating apparatus, can also play object in dry materials work Expect the effect pushed ahead, stirred.Material in three dryness storehouses has obtained the heating of thermal energy, and material carries out vacuum drying and dries After dry, reach the material of necessary requirement water content standard.

Five, the moisture that gasification generates when dry materials in three dryness storehouses is gone out by exhaust pipe by vacuum pump set pump drainage.

Six, material is in the effect of helical blade pushed ahead after drying, and material passes sequentially through three dryness storehouses after drying Discharge port, discharge device bellows elbow, wind stopping device be discharged three dryness storehouses.

The utility model has the advantages that compared with existing three vacuum dryers: a kind of lifting blade heated type three The thermal energy that the heat-conducting medium of cylinder vacuum dryer carries is transmitted to around lifting heating apparatus by lifting heating apparatus 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 three dryness storehouse rotary courses is ensured.Driving device is according to drive Dynamic Setup Controller sets different revolving speeds by the program of setting to drive the rotation of three dryness storehouses.Material is in helical-blade Also uniform stirring must have been obtained in the propulsion whipping process of piece, the drying uniform moisture degree of material is also improved.When a certain There is damage and generates leakage in block plate-type heat-pipe, does not influence the use of entire three dryness storehouses, reduces lifting blade heated type three The failure rate of vacuum dryer improves the service life of three vacuum dryers of lifting blade heated type.
