Background technology
Rotary dryer is a kind of broad-spectrum drying equipment, have production capacity big, can work continuously, characteristics such as applied widely, drying machine can be accomplished biomass fuel shredding and dry run at internal body; Dry fragmentation is carried out simultaneously; Reduce the granularity of biomass fuel, increase heat transfer area, can improve the drying effect of whizzer significantly; Improve drying efficiency, reduce drying cost.The more whizzer of present domestic employing is made up of rotating cylinder and tumbler thereof; The internal face of rotating cylinder is provided with elevate a turnable ladder formula or distribute type flight device; When rotating cylinder rotated, the flight device also rotated with rotating cylinder, and the material to be dried in the drying machine is lifted.Along with the further rotation of rotating cylinder, material to be dried breaks away from the flight device and is thrown down under the gravity effect of self, drops down onto the bottom of rotating cylinder.Afterwards, along with the rotation of rotating cylinder, be picked up once more, promote, throw down, in dropping process repeatedly, material to be dried contacts with the hot blast that gets into drying machine, carries out the caloic exchange, reaches the purpose that dehydrates.The whizzer of this structure is when dried biomass fuel, and during like stalk, branch, wood chip, bark class material, there is following shortcoming in the drying machine of this kind structure:
1. in the dry run; Because living beings quality softness, flexible, most of winding, mobile extreme difference of being prone to, this seems especially outstanding for soft stalk, and the easy winding of material concentrates near the barrel the feed end; The charging aperture that results in blockage, equipment can't run well.Influence is normal produces, and causes the raising of production cost.
2. material twines to assemble and is bulk or cotton-shaped, and the heat transfer coefficient that carries out heat exchange with heat carrier is low, and the thermal efficiency of drying machine is low;
3. phenomenons such as winding, accumulation cause dry operating mode deterioration to make material cross thermal denaturation, and burnt paste, the phenomenon of catching fire often appear in material.
Summary of the invention
The purpose of the utility model is exactly in order to solve product granularity and the non-uniform moisture that the prior art drying machine exists, and the thermal efficiency is low, and material is crossed thermal denaturation, problem such as catch fire; The broken rotating cylinder type of a kind of living beings drying machine is provided; Have compact conformation, simple structure, rationally distributed, improve the rate of heat exchange of material and heat energy, make drying materials effective; The basis less investment, the effect that floor space is little is specially adapted to the drying of biomass fuel.
To achieve these goals, the utility model adopts following technical scheme:
The broken rotating cylinder type of a kind of living beings drying machine comprises frame, motor II and transmission mechanism; Establish revolving drum on the frame, revolving drum is connected with the charging cover, and revolving drum is connected with motor II and transmission mechanism; Said revolving drum inwall is provided with flight mechanism, and the charging cover is provided with thermal medium import, charging aperture, and the charging aperture below is located in the thermal medium import; Feed end is provided with breaker in the revolving drum; Said breaker comprises broken shaft, and the broken shaft two ends are provided with bearing, broken shaft one end through the breaker transmission mechanism be connected with motor I, the other end is connected with revolving drum charging cover; Broken shaft is provided with broken blade and crushing teeth, and the axis of the vertical revolving drum of said breaker is installed.
Said breaker comprises two covers.
Said crushing teeth and blade are pressed the preset space length setting on rotating shaft, be uniformly distributed with in a circumferential direction.
Said broken blade adopts the screw-pushing type structure.
Be provided with the isolation screen cloth between the cylinder lumen of breaker and revolving drum, be provided with the isolation screen cloth between charging cover and revolving drum.
Motor II, motor I are frequency control motor.
The utility model operation principle: the utility model is keeping traditional revolving drum drier charging cover; On the basis of discharging cover, flight mechanism, revolving drum; The feed end dry at revolving drum is provided with breaker, and the charging cover and the breaker of revolving drum drier are combined.Run through the charging cover, perpendicular to revolving drum cylindrical shell, two cantilever rotating shafts of charging cover set inside, on rotating shaft, be provided with crushing teeth and blade by a determining deviation, be uniformly distributed with in a circumferential direction.In dry run, material is done irregular raising and spread motion in revolving drum inside, and is at the breaker of revolving drum feed end that living beings are broken simultaneously; Prevent that like this material from twining; Can not produce packing phenomenon, and, because breaker diminishes big block material; Strengthen the surface area that material contacts with hot blast, improved heat exchange efficiency to a certain extent.Air inlet can make hot blast fully contact with material below breaker like this, and the heat and mass transfer enhancement process improves the thermal efficiency of drying machine greatly.The rotary speed of breaker is all stepless adjustable in certain range of speeds, can be directed against different grain size, and material of different nature is selected suitable rotating speed, obtains satisfactory dry products.
The beneficial effect of the utility model is:
1. feed end is provided with breaker, has improved material in barrel and contact area hot blast, has improved heat exchange efficiency;
2. crushing device has also driven the turbulent flow phenomenon of hot blast and material, has improved the heat and mass effect;
3. broken blade adopts the screw-pushing type form, through main story or counter-rotating, can control the material degree of crushing, obtains satisfactory product;
4. breaker adopts stepless speed regulation, selects suitable rotating speed to different materials, and the flexibility of control is high.
