Description
Technical field
The present invention relates to grain field, more particularly, to a kind of drying unit for grain drier.
Background technology
At present, the popularity rate that grain machineryization is dried is very low, main that the grain in drying tower is heated using boiler
Drying operation, its shortcoming is exactly that thermal loss is big in drying course, wastes the energy, causes environmental pollution；In addition, in drying tower
Grain uneven, the peripheral grain that is heated may overheat and cause coking, and the grain at center because it is heated it is less cause not take off
Water, causes grain quality to decline, and drying effect is poor.
The content of the invention
Present invention seek to address that there is provided a kind of drying unit for grain drier for drawbacks described above.
In order to overcome defect present in background technology, the technical solution adopted for the present invention to solve the technical problems is：
A kind of drying unit for grain drier, including set in frame, in addition to frame hot air apparatus, cooling air unit, two
Hollow drying pipe, drying are provided with individual symmetrically arranged drying cavity one and drying cavity two, the drying cavity one and drying cavity two
Tube top end is less than the top of drying cavity one and drying cavity two, and drying pipe bottom end is equipped with feeding packing auger, the hot air apparatus and
Cooling air unit respectively connects the bottom of drying cavity one and the bottom of drying cavity two, and hot air inlet and cold air inlet are arranged at
The bottom of feeding packing auger, the hot air apparatus connects drying cavity one and drying cavity two by hot blast distributing valve.
In the preferred embodiment of the present invention, hot air apparatus includes air pump, drying heater, warm-air pipe and air intake
Pipe, air pump is sequentially connected drying heater and warm-air pipe, and warm-air pipe connection hot-air distributor, hot-air distributor connects two respectively
Blast pipe one end, the blast pipe other end respectively connects the bottom of drying cavity one and the bottom of drying cavity two, real by drying heater
Now to the heating in drying cavity one and drying cavity two, grain heat-drying is realized.
In the preferred embodiment of the present invention, cooling air unit includes blower fan one and blower fan two, the connection drying of blower fan one
The bottom of chamber one, the connection of blower fan two drying cavity two bottom is realized to drying cavity one and drying cavity two by blower fan one and blower fan two
Cold wind is dried, and realizes the temperature equalization in drying cavity one and drying cavity two, reduces the coking of grain.
In the preferred embodiment of the present invention, drying cavity one and the bottom end of drying cavity two are additionally provided with material pneumatic distribution
Valve, can be achieved material two kinds of functions of discharging and air inlet, and discharging when can not air inlet, can not be discharged in air inlet, realize dry
The normal operation of equipment for drying.
The beneficial effects of the invention are as follows：It is simple in construction, by drying the cooperation of pipe and feeding packing auger, realize the He of drying cavity one
The grain of the inner bottom part of drying cavity two is constantly blown out to drying cavity one and drying cavity two by hot air apparatus and cooling air unit, is realized
The circulation drying of grain；Again because hot air apparatus replaces the lasting air intake of air intake and cooling air unit so that drying cavity one and drying
Temperature equalization in chamber two, reduces the coking of grain, effectively realizes the uniform drying of grain.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
A kind of drying unit for grain drier as shown in Figure 1, including the heat set in frame 1, in addition to frame 1
Set in wind apparatus 2, cooling air unit 3, two symmetrically arranged drying cavities 1 and drying cavity 25, drying cavity 1 and drying cavity 25
There is hollow drying pipe 6, drying pipe 6 top is dried the bottom end of pipe 6 and be equipped with less than the top of drying cavity 1 and drying cavity 25
Feeding packing auger 7, hot air apparatus 2 and cooling air unit 3 respectively connect the bottom of drying cavity 1 and the bottom of drying cavity 25, and hot blast enters
Air port 8 and cold air inlet 9 are arranged at the bottom of feeding packing auger 7, and hot air apparatus 2 connects drying cavity by hot blast distributing valve 10
One 4 and drying cavity 25.
Hot air apparatus includes air pump 11, drying heater 12, warm-air pipe 13 and blast pipe 14, and air pump 11 is sequentially connected drying
Heater 12 and warm-air pipe 13, the connection hot-air distributor 10 of warm-air pipe 13, hot-air distributor 10 connect two blast pipes 14 respectively
One end, the other end of blast pipe 14 respectively connects the bottom of drying cavity 1 and the bottom of drying cavity 25.
Cooling air unit includes blower fan 1 and blower fan 2 16, the connection drying cavity 1 of blower fan 1 bottom, the blower fan
2 16 connection drying cavity 25 bottoms；Drying cavity 1 and the bottom end of drying cavity 25 are additionally provided with material pneumatic distributing valve 17, and material
