Description
Technical field
The utility model relates to agricultural technology field, specifically provides a kind of spiral ventilation silo.
Background technology
The respiration of grain, has advantages and disadvantages not in the work of guarantor's grain.From the angle consuming substrate of respiration, respiration is passive, when particularly respiration is strong, no matter is aerobic respiration or anaerobic respiration, all can affects the stability of storage, cause bad consequence.
In respiratory, the matrix be consumed becomes water, carbonic acid gas or alcohol.Infer theoretically, when aerobic respiration, release the CO of a unit
2, the consumption of dry matter is 0.68 unit, so breathe more vigorous, dry matter loss is more serious.But dry matter loss can not be equal to the loss in weight of grain, because when grain storage is breathed, not only discharge CO
2and H
2o, also will absorb CO simultaneously
2and H
2o.
Calculating by breathing general equation, consuming 1 gram of dry matter and can release 600 grams of water, by breathing the water produced, still remaining on grain intragranular, so can go out to increase its water content.In this case, if grain heap is not only stuffy but also do not stir, then make due to moisture equilibrium at dry side the relative temperature in space increase, breathing can be impelled so again stronger, and microorganism and storehouse worm are bred in a large number.Thus cause grain mouldy, rotten.
Time institute's liberated heat is breathed in grain storage, and only have fraction for the activity of sustaining life and synthesis novel substance, major part is then discharged into external (this part heat is called as respiration heat), and the temperature thus making grain pile increases.In the season of mercury dropped, in grain heap, lower floor still keeps high temperature, is exactly caused by the respiration of grain and bad thermal conductivity thereof.The high temperature of grain heap can impel to be breathed vigorous, and to create conditions for worm, mould breeding, thus accelerates stored grain quality ageing.
Because the aerobic respiration of grain and anaerobic respiration all can produce CO
2, so infrequently stirring in grain heap, again nonventilated situation, CO
2even can accumulate gradually on upper strata in lower floor, middle level, respiratory intensity is larger, then accumulate the more.CO
2content increases, and can slow down the speed of breathing, if concentration is higher, aerobic respiration also can be made to change anaerobic respiration into.
It can thus be appreciated that, the CO produced when grain is breathed
2, moisture and heat energy, all produce harmful effect to grain storage, if their actings in conjunction are in grain, then the safety for grain storage is just more unfavorable.So during keeping, grain respiration should be made as far as possible to reduce to bottom line.
For this reason silo Design of ventilation grain store in concerning important.
Summary of the invention
The purpose of this utility model is to provide a kind of spiral ventilation silo, permeability cell and the large a kind of spiral ventilation silo of grain contact area.
The utility model is by the following technical solutions to achieve these goals:
A kind of spiral ventilation silo, it comprises warehouse, is provided with helix tube in warehouse, and helix tube is evenly equipped with through hole, and the cross section of helix tube is rectangle.
In technique scheme, warehouse top is provided with blower fan, and blower fan connects the upper end open of helix tube.
In technique scheme, upper end open and the lower ending opening of helix tube are provided with Air Filter.
In technique scheme, bottom warehouse, be provided with lower ventilation storehouse, between lower ventilation storehouse and warehouse, be provided with stainless steel wire sieve.
In technique scheme, blower fan by Bracket setting in exit, ventilation storehouse.
In technique scheme, the aspect ratio of the cross section of helix tube and ventilation duct is 5:1.
Because the utility model adopts technique scheme, therefore possess following beneficial effect:
Helical pipe of the present utility model adopts rectangular configuration, compares traditional circular pipe type structure, and more greatly, ventilating permeability effect is better for its contact area with grain.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below the utility model is described further:
A kind of spiral ventilation silo, it comprises warehouse 5, is provided with helix tube 6 in warehouse 5, helix tube 6 is evenly equipped with through hole 1, and the cross section of helix tube 6 is rectangle.Helical pipe of the present utility model adopts rectangular configuration, compares traditional circular pipe type structure, and more greatly, ventilating permeability effect is better for its contact area with grain.
In technique scheme, warehouse 5 top is provided with blower fan 3, and blower fan 3 connects the upper end open of helix tube 6.Blower fan be arranged so that its ventilation effect is better.
In technique scheme, the upper end open of helix tube 6 and lower ending opening are provided with Air Filter 4.Being arranged to there will not be in helix tube and ventilation duct of Air Filter collects the problem of ash, and the later stage does not need to collect ash to helix tube and ventilation duct and safeguards.
In technique scheme, bottom warehouse 5, be provided with lower ventilation storehouse 8, between lower ventilation storehouse 8 and warehouse, be provided with stainless steel wire sieve 7.The stainless steel wire arranged bottom warehouse can strengthen the gas permeability of seed fully.
In technique scheme, blower fan 3 is arranged on exit, ventilation storehouse by support 2.
In technique scheme, helix tube 6 is 5:1 with the aspect ratio of the cross section of ventilation duct 9.
Below by reference to the accompanying drawings the Fertilizer rod of a kind of antiseep of the present utility model is explained, but protection domain of the present utility model is not limited to this, all based on the change done by above embodiment or distortion all belong to the claimed scope of the utility model.
