Abstract
The utility model discloses grain drying devices built in a kind of elevator, include: drying main cavity, cereal are placed in the drying main cavity；Lifting device, be arranged inside the drying main cavity, for by it is described drying main cavity in bottom cereal hoisting to dry main cavity in top；Dried medium supply arrangement dries the cereal in drying main cavity for the cereal conveying high temperature dry air into the drying main cavity.The external lifting device of traditional dryer is arranged to inside drying main cavity the utility model, thus make lifting device to the heat loss through convection and low-temp radiating intensity sharp fall of surrounding air, it is practically negligible；To directly eliminate the external bring heat loss of lifting device, grain-drying speed is improved.
Description
Technical field
The utility model relates to dryer design fields, and in particular to grain drying device built in a kind of elevator.
Background technique
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 become main force's product in China's drying machinery.
Batch grain drying machine, last century firstly appear in Japan, are passed to Taiwan later, have played weight to the Rice Production in Taiwan
It acts on；Interior ground is imported by Taiwan enterprise again after reform and opening-up；In the circulation migration of product, technically pay attention to inheriting rare wound
Newly.
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 from top, is looped back and forth like this, 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 in dryer section from drying pusher side side, to drying
It is discharged after grain-drying in section from the opposite other end；In circulation 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 is: dry
The heat (enthalpy) that dry air is exported in drying process is equal with heat (enthalpy) of drying process import.
Because dry empty during the hot and humid area containing wet stock dry this " constant enthalpy " occurred in drying device
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 function, 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.
So directly carrying out heat and mass for damp grain and dry air, the grain drying machine of hot and humid area goes out
Wind carries out heat recovery, is not " waste heat recycling ", 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 used in batch grain drying machine is exported in dryer section
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
1/3 or more of warm dry air and surrounding air enthalpy difference；
The heat (enthalpy) that batch grain drying machine dry air is exported in dryer section is substantially lower 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.
