The fixed support of root metal strip, heat conducting pipe are fixedly connected with the warehouse in the feed inlet in roller drying storehouse, discharge port by metal strip
It is integrated.
2-5 metal strips in the feed inlet in roller drying storehouse, discharge port above warehouse do not influence the disengaging roller of material
Dryness storehouse.
The bottom plate of the cored screw blade of the heated type helical blade is fixedly connected with the warehouse in roller drying storehouse, empty
Bottom plate on the trapezoidal lower end of heart helical blade, which is increased, is connected and fixed area with roller drying storehouse warehouse, has ensured that roller is dry
The stability of cored screw blade in dry storehouse avoids the warehouse in cored screw leaf abscission roller drying storehouse.
Heated type helical blade in the roller drying storehouse is 1-8.
Material in roller drying storehouse is under the rotation progradation of heated type helical blade, and material is from roller drying storehouse
Discharge outlet flow progresses of the feed inlet to roller drying storehouse.
The thermal energy import of the heat conducting pipe of the heated type helical blade moving on the bellows elbow of discharge device is close
Extend among seal apparatus, the thermal energy import of heat conducting pipe is connected on the heating device of peripheral hardware by thermal energy conduit, and peripheral hardware adds
Heat-conducting medium after thermal heating enters the hollow of heated type helical blade through the thermal energy import of heat conducting pipe by thermal energy conduit
The inside of helical blade.
When the heat conducting pipe of heated type helical blade is with roller drying storehouse synchronous rotary, between bellows elbow and heat conducting pipe
By dynamic sealing device come dynamic sealing, gas leakage is not generated.
The thermal energy of the heat conducting pipe of the heated type helical blade export on the bellows elbow of feeding device move it is close
Extend among seal apparatus；The thermal energy outlet of the heat conducting pipe of heated type helical blade is connected to the heating of peripheral hardware by thermal energy conduit
On device；Heat-conducting medium after heat dissipation is heated again by the heating device of peripheral hardware, and the heat-conducting medium after heating is led by thermal energy
Pipe enters the inside of the cored screw blade of heated type helical blade through the thermal energy import of heat conducting pipe.
The junction of the heat conducting pipe and bellows elbow that extend bellows elbow is by dynamic sealing device come dynamic sealing；
While heat conducting pipe rotates, the junction of heat conducting pipe and bellows elbow is sealed air-tight.
The junction of the heat conducting pipe and bellows elbow by dynamic sealing device come dynamic sealing, can be to avoid storehouse outside
Air leaks into roller drying storehouse the junction of heat conducting pipe and bellows elbow.
By the carrying of heat-conducting medium, the thermal energy that heat-conducting medium carries directly passes through the thermal energy that the heating device of peripheral hardware generates
Thermally conductive heating is carried out to material in cored screw blade.
The heat-conducting medium is conduction oil or water.
The heated type helical blade can give the thermally conductive heating of material, and heated type helical blade can also be played in material
The effect that material is pushed ahead, is stirred when dry work.
Material must also obtain uniform stirring, the drying moisture of material in the propulsion whipping process of heated type helical blade
The uniformity is also improved.
The conductive drying energy consumption index of internal heating type roller drying machine is 3500-4500 kilojoule per kilogram of water, and to draining off
Dry is 5500-8500 kilojoule per kilogram of water；This is because the conductive drying of internal heating type roller drying machine does not need Hot-blast Heating
Material is small by the thermal losses for being vented lost.
The workflow of the drying of the material of internal heating type roller drying machine is as follows:
One, start driving device, under driving device induced effect, roller drying storehouse rotates fortune on support roller in roller drying storehouse
It is dynamic.
Two, after starting wind stopping device, wet stock to be dried passes sequentially through the hopper of feeding device, wind stopping device, ripple threeway
Pipe, the feed inlet in roller drying storehouse enter in roller drying storehouse.The rotation of material in roller drying storehouse in heated type helical blade
Turn 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 helical blade, heat radiation carry out thermally conductive heating to material around cored screw blade, the material in roller drying storehouse
The thermally conductive heating of thermal energy is obtained.
Four, the moisture that the moisture vaporization in roller drying storehouse when dry materials in material generates is filled by exhaust outlet by exhaust
It sets pump drainage to go out, after material carries out vacuum drying drying, reaches the material of necessary requirement water content standard.
Five, roller drying storehouse is discharged in the discharge port that material passes sequentially through roller drying storehouse after drying.
The present invention has the advantages that compared with existing roller drying machine: a kind of heated type roller drying machine is according to object
The demand of the drying quality of material, the discharge port in roller drying storehouse is by setting installation or does not install discharge device, and selection is to draining off
Dry or vacuum drying, the drying quality of Lai Tigao material.Bellows elbow avoids the displacement between bump joint and wind stopping device
Vibration causes to leak, and gas is avoided to enter in roller drying storehouse.Heated type helical blade can give the thermally conductive heating of material, heated type
Helical blade can also play the role of pushing ahead material when dry materials work, stir.Driving device is according to control
Device sets different revolving speeds by the program of setting to drive the rotation in roller drying storehouse.Exhaust apparatus is in dry materials process
In have the function that balanced hydrofuge, thermal energy can the residence time be long in roller drying storehouse, increases effective use of thermal energy
Rate enhances the drying efficiency of drying equipment.
