Description
Technical field
The utility model is related to the Grain storage device used in agricultural machining, and in particular to a kind of positive/negative-pressure aeration-drying
The improved technology of the ventilation tubular construction of silo.
Background technology
Silo is one of grain processing equipment, and the storehouse of grain to be processed in bulk is mainly stored during grain processing
Storehouse.Agricultural silo can for having grain in reserve, feed equigranular and granular material.The cost of mechanization silo is typically than machinery
The cost for changing chamber storehouse is high by 1/3 or so, but can shorten the handling flow of material, reduction operation and maintenance cost, eliminates heavy
Packed operation, is conducive to mechanization, automated job, therefore has turned into one of topmost silo form.The planar shaped of silo
Shape has square, rectangle, polygon and circle etc..The bulkhead reasonable stress of round silo, thus set in soil investigation, soil exploration and basis
Timing is all it should be particularly noted that materials economy, so most widely used.When the material single varieties or smaller reserves of storage, with only
Vertical storehouse or single-row arrangement.When the material kind of storage is more or during big reserves, then arranges storehouse in groups.Space between silo claims star
Storehouse, is also available for utilizing.
Chinese patent literature CN203467255U discloses grain processing positive/negative-pressure aeration-drying silo, and the patent changes
To carry out machinery rolling dry, it is necessary to which periodicity export repeatedly transports drying machine for storage silo after traditional mechanical drying machine is dried
Dry mode.But easily carry grain between the central ventilation pipe of the patent secretly, air vent is easily blocked by grain, causes ventilation
Effect is bad.
The content of the invention
The utility model provides a kind of grain processing positive/negative-pressure aeration-drying silo, and the utility model solves Chinese special
Easily carry grain disclosed in sharp document CN203467255U between grain processing positive/negative-pressure aeration-drying silo, central ventilation pipe secretly
Food, air vent is easily blocked by grain, causes the problem of ventilation effect is bad.
To solve the above problems, the utility model is adopted the following technical scheme that：Grain processing positive/negative-pressure aeration-drying cylinder
Storehouse, including silo roof, silo body；Silo roof upper end, which is provided with ventilating opening, silo body inwall, is fixed with outer shroud ventilated cage, outer shroud ventilation cage ring
Shape is uniformly distributed, and there is a ventilation duct at the center in silo body, and ventilation duct is included under a vertical tube straight down, helix tube, helix tube
There is ventilation joint side；The bottom of one vertical tube connection helix tube upper end straight down, vertical tube and helix tube connects ventilation respectively
Machine.
Ventilation duct of the present utility model is by the way of vertical tube and helix tube are combined, it is to avoid grain blocking, ventilation effect
It is really good.Using the ventilation duct of helical structure, grain can glide along helical structure, will not carry grain secretly；Negative pressure drying is favourable
The moisture in grain grain, precipitate into surface, so as to easily be taken away by dry air from grain intragranular portion.Positive pressuring drying wind direction and negative pressure
Dry on the contrary, advantageously reduce the gradation of moisture problem produced by unidirectional ventilation, make moisture more uniform.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the structural representation of the utility model ventilation duct.
Symbol description in figure：Silo roof 1, silo body 2, outer shroud ventilated cage 3, ventilation duct 4, divulge information joint 4-1, ventilation blower 5, sedimentation
Interlayer 6, dividing wall 7, ventilating opening 8.
Embodiment
The utility model is described in detail with optimal embodiment below.
As shown in Figure 1-2, grain processing positive/negative-pressure aeration-drying silo, including silo roof 1, silo body 2；The upper end of silo roof 1 is set
It is equipped with ventilating opening 8, the inwall of silo body 2 and is fixed with outer shroud ventilated cage 3, the annular of outer shroud ventilated cage 3 is uniformly distributed；Silo body 2 is set below
Sedimentation interlayer 6 and dividing wall 7 are equipped with, the outlet of ventilation blower 5 has exhaust pipeline, and exhaust pipeline is connected in sedimentation interlayer 6.Row
The air inlet pipeline dividing wall 7 of air pipe line and ventilation blower 5 is separated, it is to avoid in moisture enters to put in storage, described in the structure and background technology
Patent structure is identical.It is of the present utility model improvement content be：There is ventilation duct 4 at center in silo body 2, and ventilation duct 4 includes one and erected
There is ventilation joint 4-1 straight downward vertical tube, helix tube, helix tube downside；One vertical tube connection helix tube upper end straight down,
The bottom of vertical tube and helix tube connects ventilation blower 5 respectively.
Positive draft method：Grain is loaded into silo, ventilation blower 5 is opened, dry air is entered by the ventilation duct 4 at storehouse center
Enter and pass through damp grain layer to enter outer shroud ventilated cage 3, while moisture is taken away；Ventilating opening 8 of the malaria through silo roof 1 is discharged into
Air.
Exhaust ventilation method：Grain is loaded into silo, ventilation blower 5 is opened, dry air enters to put in storage interior, will through damp grain
Grain moisture content is taken away, by the ventilation duct 4 at storehouse center, and the air outlet then through ventilation blower 5 is discharged into sedimentation interlayer 6.
The utility model technology is led to for grain processing positive/negative-pressure disclosed in Chinese patent literature CN203467255U
Air-dry dry silo to be improved, improvement is the structure in ventilation duct, ventilation duct be using by the way of vertical tube and helix tube combination,
Grain blocking is avoided, ventilation effect is good.Negative pressure drying is conducive to moisture in grain grain, and surface is precipitate into from grain intragranular portion, so that
Easily taken away by dry air.Positive pressuring drying wind direction is with negative pressure drying on the contrary, advantageously reducing the water produced by unidirectional ventilation
Divide gradient problem, make moisture more uniform.
Finally it should be noted that：Obviously, above-described embodiment is only intended to clearly illustrate the utility model example,
And the not restriction to embodiment.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.And thus
Among the obvious changes or variations amplified out is still in protection domain of the present utility model.
