The utility model belongs to a kind of granule materials is carried out dry drying machine, is specifically related to a kind of frictional heating formula drying machine.
Background technology
Frictional heating formula drying machine is provided with charging basket, in the charging basket bottom paddle is installed, utilize driven by motor paddle high speed rotating during work, the granule materials that stirs the charging basket receptacle rolls at a high speed, because between paddle and the granule materials, acutely friction between granule materials and the granule materials, make the granule materials heating, thereby obtain drying.
But existing frictional heating formula drying machine has the following disadvantages:
Though one, when work near the granule materials of charging basket bottom at a high speed, acutely roll, but from the bottom of material to upper epidermis, the severe degree that material rolls more and more reduces, granule materials until the top layer, top can only be that disturbance at a slow speed takes place, therefore, be in the violent friction of granule materials and the heating rapidly of charging basket bottom, and be in the just slight friction of top layer granule materials and the slowly heating on charging basket top.Though, in the process of rolling, the granule materials on charging basket top may migrate to the charging basket bottom gradually, the granule materials of charging basket bottom also may migrate to charging basket top gradually, finally make whole bucket material temperature reach even substantially, but this after all speed of migrating up and down is very slow, and the movement tendency of migrating up and down has contingency, lack systematicness, certainty, mandatory, thereby whole bucket material needs the long period just can reach uniform high temperature, it is dry to need the long period just can reach even heating, and the stirring motor power of rotation is bigger at a high speed, so it is more to need to consume electric energy.
Two, the height of charging basket the inside splendid attire granule materials is restricted, because: if the height of granule materials splendid attire is too big, the granule materials that then is in the surface may not roll substantially, can't frictional heating, and may need just can run to the charging basket bottom through a very long time, thereby a kind of unbalanced phenomenon can occur: the granule materials that was in the bottom originally is the excessive heating drying, and that the granule materials that was in top is originally still failed heating is dry, thereby whole bucket material still can not drain, and must continue to stir.Occur for fear of above-mentioned unreasonable, unbalanced phenomenon, can only limit the height of granule materials splendid attire in the charging basket, the height of splendid attire granule materials can only be equivalent to about half of paddle diameter usually.
Three, the height owing to charging basket splendid attire granule materials is restricted, can only be equivalent to about half of paddle diameter, but must guarantee that each drying can finish the workload of certain volume, and therefore can only strengthen the diameter of charging basket and paddle, could guarantee operating rate.Because the diameter of paddle is big, driving its rotation needs the electric energy of consumption big, and granule materials is big to the resistance torque of paddle.
Four, because the height of charging basket the inside splendid attire granule materials is little, thereby granule materials is big inadequately to the pressure of paddle, the inner mutual pressure of granule materials is also less, granule materials internal loose, leakiness in the whipping process, the surface extruding force is less, skin-friction force is less, has influence on the frictional heating effect.
For above-mentioned reasons, the available power ratio of existing frictional heating formula drying machine is less, useless power large percentage, and whole energy consumption is bigger, and the electric weight that granule materials consumed of every processing unit volume is bigger.(so-called here available power is meant the power that can directly make the granule materials frictional heating and be dried to resonable degree; And useless power is meant that a part of power except available power, and this part useless power finally may show as and make that the motor feels hot, or shows as the kinetic energy loss of paddle, or shows as and make the sub-fraction material overheated or the like.Overheated material need not continue drying, thereby drives it and rub, and belongs to flog a dead horse yet).

The utlity model has following advantage and effect:
When 1, the utility model is worked, the first motor-driven paddle high speed rotating, the vertical screw rod slow rotation of second motor-driven; The granule materials that paddle stirs the charging basket bottom rolls at a high speed, and the granule materials of charging basket bottom is generated heat because of violent friction, thus the drying of obtaining.Simultaneously, because action of centrifugal force, the granule materials of charging basket bottom can throw away from following circulation through hole after frictional heating gradually, enter the middle and lower part of vertical cylinder, because the squeezing action of vertical screw rod, these granule materials move on gradually in vertical cylinder, and flow into charging basket top again by the cocycle passage; After the granule materials of charging basket bottom was got rid of the bottom of vertical cylinder gradually, the granule materials above the paddle replenished downwards automatically, so constantly migrates up and down circularly, made that all particulates material is all evenly rubbed, generates heat, drying.
2, the utility model is because the movement tendency that granule materials is migrated up and down has systematicness, certainty, mandatory, circulation rate is fast, circulating effect is good, the too high and problem that can't circulate, can't evenly generate heat of the height that does not have a splendid attire material in the charging basket, thereby the utility model splendid attire height of materials is not subjected to the paddle diameter restrictions, the splendid attire height of materials also can be greater than the paddle diameter, and the splendid attire height of materials can be than traditional structure height.
3, can finish under the prerequisite of equal volume workload in each operating process, the diameter of paddle of the present utility model can be more much smaller than traditional structure, reason is as follows: (1), vertical cylinder of the present utility model can hold a part of material, therefore charging basket volume, diameter can dwindle, and the paddle diameter can dwindle; (2), the height of charging basket splendid attire material of the present utility model is big, thereby under the situation that the demand volume equates, the charging basket diameter can dwindle, the paddle diameter can dwindle.
4, the available power large percentage of the utility model drying machine, useless power proportions is less, whole energy consumption reduces, the electric weight that granule materials consumed of every processing unit volume is less, can be than traditional structure power saving 30～50%, reason is as follows: (1), granule materials constantly circulate through the charging basket bottom, and heating is evenly avoided the unnecessary loss of the overheated initiation of local material; (2), the utility model paddle diameter is little, kinetic energy loss is little, resistance is little; (3), the height of the utility model when work granule materials splendid attire is big, the inner mutual pressure of granule materials is also bigger, granule materials denser in the whipping process, skin-friction force is bigger, frictional heating is effective; (4) though the utility model is set up the rotation of the second motor-driven screw rod, and second motor only needs slow rotation, power consumption is little.
