Utility model works principle:
Centrifugal blower 22 is with by motor I 24 and is endeavoured, by the hot-air (drying medium) after heating in heater 21 under the effect of centrifugal high pressure fan, to there is the air-flow of certain pressure and temperature by air-flow supervisor 17-2, surperficial to material to be dried by the branch jet pipe 17-3 jet impact of a few row's particular arrangement.Owing to spraying the flow velocity higher (generally between 10 ~ 30m/s) of gas, when after its peening particle material, the obstruction of material to vertical jet-stream wind makes jet-stream wind reflex to immediately around among material.Namely, when granular material is positioned at arid region, material is not only subject to the impact of multi-branched nozzle ejection high velocity air, is also subject to washing away of reflected gas stream simultaneously; And rotate continuously with given pace due to material cylinder, material is in a kind of state of continuous rolling movement all the time.Final result is that all materials in material cylinder by the air-flow of high-speed motion parcel and can wash away, and thus heat utilization efficiency is high, improves rate of drying greatly.Meanwhile, the air intake port of centrifugal blower can be connected with the return air inlet of exit casing by conduit, and be covered with insulation material at the interlayer such as cylindrical shell and housing, reduce heat loss to greatest extent, improve hot service efficiency, reach the effect of energy-conserving and environment-protective.In order to monitor the change of dry gas stream, air intake and return air end all can be provided with temperature and humidity measuring instrument.
The feeding of material is then realized by feeding and discharging mechanism with discharge.During feeding, feeding end is threaded to top, material enters into efficient drying region (cylindrical shell) by slope.After drying after a while, material reaches corresponding requirements, and drying device needs discharge.Now, feeding end is rotated counterclockwise 180 degree, be located at immediately below air-flow supervisor, feeding and discharging mechanism changes exhaust end into and carries out discharge.For ease of the carrying out of this process, the handle of rotatable elevating mechanism, makes material drum-inclined angle 0 ~ 20 degree of change, improves discharge efficiency.
The utility model hothouse adopts drum-type, and this not only can reach larger charge but also rotation by cylinder is heated evenly to make material.Its intermediate roll internal diameter DB>=200mm, external pressure p=0.1MPa, cylinder computational length L>=300mm, the thickness G reatT.GreaT.GT=2mm of cylinder.
Inner wall of rotary drum is installed the stirring horizontal bar of agitaion, has ensured that, in whole dry run, the material in hothouse can be in rollover states with this always.Stir the damage of horizontal bar to material to reduce in rotary course, and consider for should be harmless in food processing, therefore the material stirring horizontal bar adopts steel pipe.Stir the size of horizontal bar: large footpath 5 ~ 20mm, length >=150mm.
Due to material cylinder horizontal positioned, for reaching certain charge, the semicircle sieve plate 11 of two central through holes being housed in the front end of material cylinder, cooperatively interacting thus avoiding material to be revealed by cylinder end.This sieve plate 11 as the return air inlet of air-flow, can not only also be convenient to replacing and the maintenance of central fluidizing gas supervisor simultaneously.
Gas shock mechanism comprises air-flow supervisor, branch's jet pipe, nozzle and block.Wherein, air-flow supervisor is connected with centrifugal blower; Thermal current is after air-flow supervisor enters branch's jet pipe, and jet impact is to material to be dried surface.During drying machine operation, according to the characteristic of different material, position and the scantling thereof of air-flow supervisor can be regulated, thus realize the structural parameters changes within the specific limits such as jet size, jet pipe height, jet pipe inclination angle.
Due to the utility model design for be the drying of agricultural product material, during using different materials as experimental subjects, its size is not quite similar, therefore requires that the coverage of nozzle can be done to adjust accordingly.This purpose is reached by the large I changing nozzle inside diameter.At this, its internal diameter is designed to 10mm, 15mm and 20mm etc. are multiple.
In the utility model ventilating pipe type whizzer, branch's jet pipe is generally matrix arrangement mode in the projection of horizontal plane, this mode can cause below jet pipe different with stirring intensity with the gas shock intensity suffered by the material below nozzle gap, and namely the material local heating at diverse location place is uneven.For solving the problem, branch's jet pipe of the utility model drying machine preferably adopts helical row mode.Compared with above-mentioned matrix form, helical row mode can reduce 2/3 by the projection pitch of Shi Ge branch jet pipe on plummet face, and then below Shi Ge branch jet pipe and nozzle gap below the gas shock intensity suffered by material more identical with stirring intensity, material be heated evenly.
Take such as red date as experimental subjects, learn from its physical characteristic, red date length average out to 30mm, diameter 20mm.Therefore, select air-flow supervisor center distance to be 60mm, the centerlines 30 degree of adjacent two air-flow supervisors.Total number then calculates according to the radial dimension of hothouse, namely airflow duct is arranged altogether two rows totally six jet pipes.
When needs when filling with substance, the feeding end of feeding and discharging mechanism is threaded to air-flow supervisor 17-2 above and open door, material enters into efficient drying region (cylindrical shell) by slope.After drying after a while, material reaches corresponding requirements, and drying device needs discharging.Now, by feeding end dextrorotation turnback, be located at immediately below air-flow supervisor, drawing-in device changes exhaust end into and carries out discharge.
The elevating mechanism of drying machine mainly comprises lifting screw, lifting nut, and lifting torsion bar, elevating bracket etc., wherein, lifting screw has the screw thread needed for worm drive.Manual rocking-turn lifting torsion bar, by lifting screw, the cooperation transmitting torque of lifting nut, and lifting screw is rotated up or down, under the effect of spiral torsion, vehicle frame side is constantly risen or is declined, thus realizes elevating function.
Compared with prior art, the utility model not only will consider the implementation of cylinder and gas jet impact dry technology advantage in the design to drum-type gas jet impact drying device, also to consider both combinations simultaneously, make it can not only play respective technical advantage, can also the deficiency of complementary technology separately.The utility model compared with conventional formula whizzer, this machine not only have the dry heat transfer coefficient of gas shock high, to the adaptable technical advantage of material, can embody again that rotary drying production capacity is large, the technical characterstic of applied range.And this machinery utilization gas-heated, the product for different size different-diameter all can meet drying requirement, is suitable for too for heat sensitive material.Thus, the utility model be a kind of rational in infrastructure, the dry heat transfer coefficient of gas shock is high, to material strong adaptability, dry production capacity is large, can be applicable to different size product, applied range, economical and practical drum-type gas jet impact drying machine.
