Description
Technical field
The present invention relates to a kind of silo inner and outer ring flow control systems, belong to silo thermostatic control system technical field.
Background technique
Food problem is one of pressing issues highly visible now, and China every year will as the first in the world populous nation
A large amount of grain is consumed, has grain country that could stablize healthily developing industry, national defence, service trade, science and culture cause etc..
Food problem is not only economy and livelihood issues, and development and safety problem.Fast development and people with green food
The continuous improvement of living standard, grain green storage technology have arrived significant progress China.
With the rapid development of our country's economy, View of Grain Storage Technoiogy is changed into from conventional stored condition to low temperature, quasi- low temperature etc.
The transformation of temperature control the mean of storing grain.But the continuous variation for storing environment temperature in the period can impact the quality of grain, it is existing
The temperature control of silo need artificial monitoring to adjust, not only cause response not in time, operation large labor intensity, but also energy wave
Fei great, not environmentally.Meanwhile existing traditional silo ventilating system is open system, ventilation introduces extraneous seleced air
Pressure is passed through grain heap, replaces the air in grain heap, carries out sufficient exchanges of mass and energy with grain heap, reaching reduces grain heap temperature
Create the target of low temperature environment.But this open-plenum also has a fatal problem, is exactly that Grain Quantity will substantially subtract
Few, single ventilation Grain Quantity loss can reach the 0.5%~0.8% of total amount, and it mainly includes grain that Grain Quantity, which will be greatly decreased,
Available moisture in food is lost, and main function of this moisture in grain is the toughness for improving grain, excessively dry grain
Food is not easy to take care of, and either in transport or during accumulation storage, excessively dry grain is easy cracking, is crushed,
Biggish loss is brought to storage enterprise in this way, therefore the comprehensive benefit of the ventilation of the prior art is very low.
Summary of the invention
The present invention provides novel granary zero and ventilating system is lost for deficiency above-mentioned in the prior art.Hereinafter give
Go out about brief overview of the invention, in order to provide a basic understanding of certain aspects of the invention.It should be appreciated that this
General introduction is not about exhaustive general introduction of the invention.It is not intended to determine key or pith of the invention, also not
It is intended to limit the scope of the invention.
Technical solution of the present invention:
Ventilating system is lost in novel granary zero, and including the silo being mounted on ground level, the lateral wall of silo is disposed with storehouse
Outer cooling pipe and ground-cooling temperature-lowering pipe, the lateral wall upper end of the silo, which is machined with outside upper end ground-cooling temperature-lowering port and upper end storehouse, to drop
Warm port, the lateral wall lower end of silo are machined with outside the storehouse of lower end the port that cools down, the upper and lower ends difference of cooling pipe outside the storehouse
It is connected to cooling port outside cool down outside the storehouse of upper end port and lower end storehouse, one end of ground-cooling temperature-lowering pipe and upper end ground-cooling temperature-lowering port connect
Logical, the other end of ground-cooling temperature-lowering pipe, which penetrates after ground level " U-tube " formed below, to be pierced by ground level and is connected to cooling pipe outside storehouse；Institute
The bottom end of cooling pipe is equipped with the first blower outside the storehouse stated.
Further, the inner sidewall of the silo there also is provided cooling pipe in storehouse, and in the storehouse upper end of cooling pipe
It is machined with upper end vent gas stream, the side wall that the lower end of cooling pipe passes through silo in storehouse is connected to cooling pipe outside storehouse.
Further, the bottom end of cooling pipe is machined with lower end vent gas stream in the storehouse, at the vent gas stream of lower end
Second blower is installed.
Further, the first valve is installed in cooling pipe in the storehouse.
Further, the second valve is installed in cooling pipe outside the storehouse, third valve is installed on ground-cooling temperature-lowering pipe.
Further, cooling pipe and the quantity of ground-cooling temperature-lowering pipe are multiple, cooling pipe and ground outside multiple storehouses outside the storehouse
Aeration-cooling circuit is formed with silo inside after cold cooling pipe is in parallel.
The invention has the following advantages:
1. silo ventilation of the invention uses full-closed structure, pass through cooling pipe and ground-cooling temperature-lowering outside cooling pipe in storehouse, storehouse
Pipe cooperates, and then utmostly reduces grain temperature in silo using extraneous cold resource, realizes ventilation process；
2. the present invention realizes ventilation process in entire silo, air-flow can be realized automatic cycle, and entire venting ring
Stream process does not realize gas exchanges with the external world, and effective guarantee is in silo ventilation process, and the grain inside silo is because of the external world
Air enters grain heap and generates the exchange of substance, and Grain Quantity is caused to reduce, and causes grain that dry problem occurs；
3. the air-flow stream of ground-cooling temperature-lowering pipe of the invention in the heat exchange structure of ground level " U-tube " formed below, silo
The heat in air-flow is swapped after " U-tube ", realizes that cold air is passed through inside silo, this exclusive structure can inhale
The cold air of below ground is received, and is able to achieve the Efficient Cycle of effective warehouse internal gas flow, and then reaches " 0 loss " ventilation.
