Description
Technical field
The present invention relates to dryer design fields, and in particular to a kind of shared grain drying device of side wall.
Background technology
Cereal develops to drying center drying mechanization technology by sunlight with drying on threshing ground, rural threshing ground go far gradually until
It disappears, is hallmark events of the traditional agriculture to modern agriculture transition.
In the drying mechanization technology equipment of cereal, batch (circulating) dryer is because combination is convenient, adapts to middle and small scale
Operation, the requirement to grain harvest production organization degree are relatively low, and as main force's product in China's drying machinery.
Batch grain drying machine, last century firstly appear in Japan, Taiwan are passed to later, to Taiwan
Rice Production has played important function；Continent is imported by Taiwan enterprise again after reform and opening-up；It is moved in the circulation of product
In shifting, technically pay attention to inheriting rare innovation.
Damp grain is disposably packed by batch grain drying machine, and disposable discharge, carries out a collection ofly after drying
Drying production.The drying production process of batch grain drying machine, under the action of elevator, the cereal quilt of grain dry motor spindle
It is transported to top, then is slowly moved downwardly to bottom, so move in circles from top, until grain-drying；Grain drying machine waist
Portion is provided with dryer section, and the drying high temperature air that hot air apparatus generates is transported to from drying pusher side side in dryer section, to drying
It is discharged from the opposite other end after grain-drying in section；In recycling each time, cereal passes through the spy of grain drying machine waist
Different " dryer section " structure, high temperature dry air passes through the gap between cereal-granules in dry segment structure, cereal surface
Moisture is come out by high temperature dry air heating evaporation；Then, cereal enters " delay section ", realizes moisture from inside cereal to surface
Diffusion, the arrival for the heated-air drying stage next time are prepared.
The dryer section of grain drying machine, exactly one constraint cereal flow downward and dry air level are promoted to pass through paddy
The structure of logistics, the exactly one group air duct institute laterally passed in and out by vertical lower grain slot and one group of hot-air that two metal otter boards enclose
The space of composition is the place that the heat of dry air and the moisture of damp grain carry out " hot and humid area "；
In the drying production of dryer, theoretically, the hot and humid area process of dry air and damp grain, is one
A process that " constant enthalpy " is expressed as on air psychrometric chart；Drying course containing wet stock, most important energy feature are：It is dry
The heat (enthalpy) that dry air is exported in drying process is equal with heat (enthalpy) of drying process import.
Because occur in drying device during drying the hot and humid area of this " constant enthalpy " containing wet stock, it is dry empty
Sensible heat is released in gas cooling, pushes to absorb heat vaporizing containing the moisture in wet stock；In this process, drying device is not done externally
The total amount of heat of work(, this therrmodynamic system of drying device is not reduced, and only partial heat turns from " sensible heat " form of dry air
" latent heat " form of water vapour is changed into, total enthalpy is constant.
So directly carrying out with dry air for damp grain heat and mass, the grain drying machine of hot and humid area goes out
Wind carries out heat recovery, is not " waste heat recovery ", but has the characteristics that " total heat recovery ", has than other heat power engineering systems
(such as internal-combustion engine system, boiler-turbine system) much higher technical meaning and commercial value.
But actual test shows：The heat (enthalpy) that dry air is exported in dryer section used in batch grain drying machine
With the heat (enthalpy) of dryer section import and unequal, there is apparent difference, it is high that difference is even as high as the import of drier section
Warm dry air and 1/3 or more of surrounding air enthalpy difference；
The heat (enthalpy) that batch grain drying machine dry air is exported in dryer section is substantially less than the heat of dryer section import
It measures (enthalpy), type is dried for the main force of batch processing amount 15T, this heat loss is up to 20~50kw, this is one serious
Heat loss.
This serious heat loss had not only reduced the enthalpy of drier section outlet air, the recuperation of heat value of outlet air, but also drop
Temperature of low cereal during tempering, reduce speed from deep layer moisture in cereal to cereal diffusion into the surface, reduce paddy
Object drying rate.

Side wall provided by the invention shares grain drying device, has the following advantages：
1. leakage thermal power of the cereal to surrounding air is greatly lowered
Under similarly drying capacity, drying capacity, a kind of side plate of the present invention shares grain drying device, adjacent dryer
Between share side plate, to reduce Drying unit wall surface nearly to the surface area of ambient air outside 50%, by Drying unit " ratio
Surface area " index reduces about half；Due to reducing the specific surface area of Drying unit and to the highwall surface area of ambient air, drying
Convection current leakage heat and radiation leakage heat of the cereal by dryer siding to surrounding air are considerably reduced in dry operational process, are improved
The enthalpy of drier section outlet air, outlet air recuperation of heat value, improve temperature of cereal during tempering, in cereal
Deep layer moisture improves grain-drying speed to the speed of cereal diffusion into the surface.
2. mechanical strength increases
Against setting between adjacent dryer, to greatly strengthen the mechanical strength of service drying unit complete machine and steady
It is qualitative；
3. drying and processing amount is big, flexibility is high
It includes more dryers that a kind of side wall of the present invention, which shares in grain drying device, can synchronize drying production,
Singly only independent production can be dried, drying and processing amount is big, and flexibility is high.
In the present embodiment, adjacent dryer shares a head cover, shares a pedestal, further improves entire cereal
The strength and stability of drying unit.
In the present embodiment, the cross section of dryer is rectangle, and long side side shares side plate between adjacent dryer, this
Sample is designed with conducive to the further leakage heat for reducing grain drying device；Certainly, the structure of dryer is simultaneously in other embodiments
It is not limited to the above, is not limited herein.
In the present embodiment, side wall shares and is also covered with insulating layer on grain drying device surrounding lateral wall；The present embodiment
By the setting of insulating layer, the further dryer side wall that reduces is to extraneous leakage warm.Wherein, polyurethane guarantor can be used in insulating layer
Warm layer also can be selected other insulating layers, is not limited herein in other embodiments certainly.
Those skilled in the art should be understood that the present invention can be implemented without departing from it with many other concrete forms
The spirit or scope of itself.Although the case study on implementation of the present invention has been described, it should be understood that the present invention should not be limited to these implementations
Example, those skilled in the art can make variation within the spirit and scope of the present invention as defined by the following claims
And modification.
