Description
Technical field
This utility model relates to a kind of agricultural installations, i.e. a kind of grain negative pressure air drying cabin.
Background technology
After the grain harvests such as Semen Maydis, water content is higher, it is impossible to directly puts storage in storage, needs drying and dehydrating.Existing grain is done
Drying method has artificial dry in the sun, mechanical drying and natural air drying etc..Artificial dry in the sun floor space is big, and drying time is long, and manpower becomes
This height.Mechanical drying many employings drying tower, involves great expense, and energy consumption is the highest, and wayward, and quality is uneven.Natural air drying is adopted more
The silo surrounded with screen cloth, the inside is provided with the ventilation duct that multiple screen cloth surrounds, and the outer end of ventilation duct connects the bulkhead that screen cloth surrounds
And communicate with air outside storehouse, natural wind takes away the moisture of grain in entering storehouse by ventilation duct.Natural-wind dry grain cost is relatively
Low, grain quality is good, is suitable to peasant household's dispersion and carries out, thus has obtained preferable popularization., due to natural wind poor stability,
Time big time little, the efficiency air-dried is difficult to ensure that, long wind-force is not enough, also can cause going mouldy of grain.Additionally, it is wet at air
Degree is too big and in the case of flowing slowly, natural wind not only will not drying grain, the most also can increase grain moisture content, even draw
Send out grain to go mouldy.
Summary of the invention

Detailed description of the invention
The total design of this utility model is that the port of the ventilation duct of air curing cabin for food can be airtight, shape under the effect of blower fan
Negative pressure is become to carry out grain dewatering operation.Introduce five kinds of embodiments below in conjunction with the accompanying drawings:
The first embodiment: the grain negative pressure air drying cabin that Fig. 1, Fig. 2 introduce, the bulkhead 1 of air drying cabin surrounds with screen cloth
Cylinder or cube, it is also possible to be other three-dimensional shapes.Branched ventilation duct 2 it is provided with inside bulkhead 1, visible in conjunction with Fig. 3, Fig. 4,
Ventilation duct 2 is also to surround with screen cloth, can be pipe, square tube, Rhizoma Sparganii pipe or rhumbatron.Can also be half rhumbatron, only two
Individual plane, also can form the section space close to half rhombus, and half rhombus sky above below half rhumbatron during loading
Between be added will form one close to complete rhombus air vent.Branched ventilation duct 2 is divided into multilamellar, and the ventilation duct between each layer is
Well mutually staggering, one blast main 3 of inner connection of each ventilation duct 2, visible in conjunction with Fig. 5, Fig. 6, blast main 3 is also by screen cloth
Surround, preferably erect the center being arranged on air drying cabin, and be connected with air-introduced machine 5.Air-introduced machine 5 can be connected on the upper of blast main 3
End, lower end or side.Enumerate in figure is to pick out air-introduced machine 5 to side in the bottom of blast main 3, and the upper end of blast main 3 can be used
Screen cloth is closed.
Compared with existing air drying cabin, the outstanding feature of this example is to have a segment distance between the outer end of ventilation duct and bulkhead.As
Shown in figure, the outer end of ventilation duct 2, within bulkhead 1, is more than 100mm with the distance of bulkhead.Air drying cabin with a diameter of 4000mm
As a example by, the distance between outer end and the bulkhead 1 of ventilation duct 2 is preferably no more than 500mm.The effect of this structure is: fill in storehouse
After grain, the outer end of ventilation duct 2 and the surrounding of blast main 3 are all blocked by grain, and the natural wind outside storehouse is difficult to enter storehouse
In.After starting air-introduced machine 5, formation negative pressure around ventilation duct 2 and blast main 3, the moisture inside grain will be negative
Discharge under the effect of pressure and seen off by air-introduced machine.
Experimental results demonstrate: although under the effect of negative pressure, the air in the middle of environment also can enter in storehouse, but the gas entered
Stream is under flow regime, and the amount entering grain is the least, and the moisture in grain is swept along the trend of discharge to be more than by air flow
Outside moisture enters the trend of grain, and the moisture in the middle of grain will gradually decrease, it is possible to meet the demand air-dried.
The grain negative pressure air drying cabin that the second embodiment: Fig. 7 is introduced is to change on the basis of the first embodiment
Entering, it is mainly characterized by: be provided with the internal diameter close fit of balloon 7, the external diameter of balloon 7 and blast main 3 in blast main 3, on balloon 7
Under be equipped with stay cord 8, stay cord 8 extends to the outside of bulkhead 1.The position of balloon 7 can be adjusted with stay cord 8.When in storehouse
When grain is filled, balloon 7 is pulled in the upper end of blast main 3.When the grain in storehouse is discontented with, the position of balloon 7 should be in grain plane
Below.In this manner it is possible to prevent blast main bad sealing and leak out, air-introduced machine 5 air inducing effect can be played to greatest extent, build
Vertical higher operating pressure.
The grain negative pressure air drying cabin that the third embodiment: Fig. 8 is introduced is to change on the basis of first two embodiment
Enter.The outer end of its ventilation duct 2 and bulkhead 1 have a segment distance, but the outer end of ventilation duct 2 is not within bulkhead, but stretch out storehouse
Wall, minimum also will be with bulkhead flush.This ventilation duct does not the most use semicanal, including half rhumbatron.Outer end at ventilation duct 2
It is furnished with connector 9, inserts connector 9 ventilation duct 2 outer end Guan Bi, extract connector 9 ventilation duct 2 outer end and open wide.
The advantage of this structure is: ambient humidity is big when, and ventilation duct 2 plugs connector 9, by air-introduced machine 5 work into
Row negative pressure air-dries.When ambient humidity is little, can remove connector 9, ventilation duct opening, i.e. reliable natural wind carries out grain air-drying work
Industry.
The grain negative pressure air drying cabin that 4th kind of embodiment: Fig. 9 is introduced belongs to the improvement of previous embodiment, is also aforementioned reality
Execute the equivalent technical solutions of example, be characterized in: branched ventilation duct 2 is erect and is arranged in air drying cabin, then converges with a blast main 3
It is followed by air-introduced machine 5.Start air-introduced machine 5, also can form negative pressure in storehouse, reach to get rid of the purpose of grain moisture content.
Described ventilation duct 2 is erect and is installed, it should also include tilting to install.
The grain negative pressure air drying cabin that 5th kind of embodiment: Figure 10 is introduced, is to change on the basis of previous embodiment
Enter, the existing setting of its ventilation duct, also there is horizontal, its blast main also has setting, also has horizontal, illustrates that ventilation duct is with total
The structure of airduct can be diversified.Additionally, be additionally arranged grain transporter 10 in the side of air drying cabin, manpower can be substituted
Grain is loaded in storehouse.
