Description
Technical field
The utility model relates to View of Grain Storage Technoiogy field more particularly to a kind of grain heap periphery standpipe ventilating systems.
Background technique
Grain in-bin drying is also referred to as drying generator or in storage drying, is that a kind of ventilation using grain warehouse and configuration is set
It applies, manual control dry air medium is dried grain in warehouse, after grain processed reaches safe moisture
With regard to the technical measures of storage hiding.In-bin drying has primary with low investment, and grain drying quality is good, the low advantage of drying cost.
Grain security moisture is related to storage temperature, inclined high-moisture grain can safe storage at low temperature, and high temperature season
Because being influenced by outer temperature, grain temperature is usually higher for grain heap periphery, realizes that whole storehouse cryopreservation investment is big, at high cost.20 DEG C or less wet
Grain desorption equilibrium relative humidity (ERH) is not higher than 70% within base moisture 15.5%, the grain temperature of the cold center portion position of large storehouse grain heap
Degree longer-term is maintained at 15 DEG C hereinafter, can be with longer-term safe storage, and the grain around grain heap aestivates grain temperature usually at 25 DEG C
~30 DEG C, safe moisture is within 14.0%.Inclined high-moisture grain needs to be aerated grain heap surrounding and upper layer grain after putting in storage
Be dried, time-consuming for conventional in-store drying (drying generator), and moisture layering is serious, and lower layer's grain is excessively dry, aeration-drying at
This height.
Utility model content
Technical problem to be solved in the utility model and the technical assignment of proposition are improved to the prior art, are provided
A kind of grain heap periphery standpipe ventilating system, solving in-store drying mode traditional in current technology, time-consuming, and drying cost is high, water
Layering is serious, the excessively dry problem of lower layer's grain.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of grain heap periphery standpipe ventilating system, which is characterized in that several ventilations including being vertically arranged in warehouse surrounding
Pipe, ventilation duct is connect by air guide channel with blower, and ventilation duct is top closed, and the wall surface of ventilation duct has opened up several lead to
Air holes.Grain heap periphery standpipe ventilating system described in the utility model carries out grain heap using the ventilation duct that warehouse surrounding is arranged in
Periphery ventilation, reduces the temperature and moisture of the grain of grain heap periphery, so that the moisture of grain reaches within safe moisture, it is real
The safe storage of existing grain.Dry power consumption is effectively reduced by the way of the ventilation of periphery in the utility model, ensures that grain heap moisture is equal
It is even, it avoids moisture layering serious, avoids in-store drying from causing lower layer's grain excessively dry, improve the quality of foodstuff preservation.
Further, the ventilation duct includes blast pipe and discharge pipe, and blast pipe and discharge pipe are along warehouse four
Weekly interval arrangement.Dry gas is entered in grain heap from blast pipe and is then discharged from adjacent discharge pipe, shortens the discharge of moisture
The temperature and moisture of the grain of grain heap periphery is effectively reduced in path, and the path for avoiding moisture from passing through in grain heap is too long to lead to grain
Food repeats to absorb moisture and be difficult to reach good drying effect.
Further, the blast pipe and discharge pipe checker wind direction are aerated, and become original blast pipe
Discharge pipe, discharge pipe originally become blast pipe, change the flow direction of dry air, improve drying effect.
Further, the ventilation hole is provided with the middle part and lower part of ventilation duct wall surface, ventilation duct top and grain heap top
Portion maintains an equal level, and enables dry air more effectively into being dried in grain heap, the slave grain heap for avoiding dry air excessive it is upper
Portion is overflowed, and improves drying efficiency.
Further, the ventilation duct is cooled down using ventilation by low pressure, small power consumption, is cooled down high-efficient.
Further, the ventilation duct is preset in warehouse surrounding, and stability in use is good, or will ventilation after grain is closed a position
Pipe is inserted into grain heap, and using flexible is strong.
Compared with prior art, the utility model advantage is：
Grain heap periphery standpipe ventilating system described in the utility model is by the way of the ventilation of periphery, and structure is simple, effectively
Dry power consumption is reduced, ensures grain heap uniform moisture, avoids the layering of grain heap moisture serious, in-store drying is avoided to lead to lower layer's grain mistake
Dry, convenient temperature control improves the quality of foodstuff preservation, reduces grain loss.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of grain heap periphery standpipe ventilating system disclosed in the utility model embodiment, structure is simple, and air permeability is good, effectively
The grain moisture content for reducing grain heap periphery, the safe storage for the inclined high moisture grain that solves the problems, such as to put in storage, reduction drying cost, guarantee grain
Eat storage quality.
As shown in Figure 1, a kind of grain heap periphery standpipe ventilating system, several ventilation ducts including being vertically arranged in warehouse surrounding
1, ventilation duct 1 is uniformly distributed along warehouse surrounding, and ventilation duct 1, which can be preset, to be fixedly mounted on warehouse surrounding or insert after grain is closed a position
Enter in grain heap, ventilation duct 1 is top closed, and 1 top of ventilation duct maintains an equal level at the top of grain heap, and ventilation duct 1 passes through air guide channel 2 and blower
3 connections, the wall surface of ventilation duct 1 have opened up several ventilation holes 4, and ventilation hole 4 is provided with the middle part and lower part of 1 wall surface of ventilation duct,
