Technical field
The present invention relates to technical field of food storage, more particularly, to a kind of silo cooling system based on intelligent control.
Background technology
Temperature is an important factor for influenceing grain quality and security, low-temperature grain-storage, that is, to maintain cereal temperature to be less than 15 DEG C
Stored, can effectively suppress grain respiration, prevent insect pest, go mouldy, delay aging and other quality deteriorations.State at present
It is interior mainly to carry out low-temperature grain-storage, including equal temperature technique of circulation, mechanical refrigeration cooling etc. using natural cooling source or plant equipment, so
And generally establish modernization grain storehouse enforcement difficulty it is larger, the design and construction of common large granary is often limited by climatic characteristic and ground
Position is managed, and needs the high and complicated refrigeration plant of cost, energy consumption is huge, adds grain storage cost, the enforcement difficulty of increasing.Profit
Annual low-temperature grain-storage technology is realized with natural cooling source and plant equipment, so far without widespread adoption and popularization.Therefore one is sought
Kind of cost is low, energy consumption is small, pollution-free, and the green grain storage method easily realized is urgent problem to be solved instantly.
The content of the invention
It is an object of the invention to provide a kind of silo cooling system based on intelligent control, to be made by dynamic circulation system
Heat and moisture in grain heap, which timely export, to be distributed, and prevents cereal temperature rise from further going mouldy.
To realize the purpose of the present invention, the technical solution adopted in the present invention is：A kind of silo based on intelligent control dissipates
Hot systems, including silo, gas-recycling plant, spiral lever apparatus and temperature field intellectual monitoring control system, the gas follow
Loop device is connected with silo upper part, forms a circulation loop, the spiral lever apparatus includes screw rod and power fills
Put, power set driving screw rod rotation, the grain being stored in silo is taken to the top of silo, silo top from grain bin bottom
The grain in portion slips down to grain bin bottom under gravity, so as to which grain forms a circulation loop, the temperature in silo
Intellectual monitoring control system includes the multiple temperature sensors and controller being arranged in silo, the gas-recycling plant and
Spiral lever apparatus is connected with controller.
Compared with prior art, the beneficial effects of the invention are as follows：Its structural system is simple, it is easy to accomplish；It does not include sky
Cooling system is modulated, therefore its energy consumption is smaller during the storage of grain；Due to which increasing spiral lever apparatus, therefore dropped in grain
During temperature, its efficiency that cools is higher than traditional barn structure radiating efficiency.Because its structure is easily realized, conventional junction is also beneficial to
The transformation of structure；Be advantageous to carry out upgrading to traditional grain storage system, the popularization of large area can also be obtained；Due to the system
For intelligence control system, therefore automaticity is higher than traditional grain storage system, so as to which human cost be greatly saved.

Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It is it should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
It should be noted that " connection " described herein and the word for expressing " connection ", such as " being connected ",
" connected " etc., it both may refer to a certain part and had been directly connected to another part, and can also refer to a certain part and pass through other portions
Part is connected with another part.
Foodstuff preservation is in an artificial ecological system, in this specific ecosystem, biological factor (grain, evil
Worm, microorganism) pass interdepend, connect each other, mutually restricting between abiotic factor (temperature, moisture, gas) be present
System.In grain storage management, most important and most important factor is the change of temperature.The safety of the change reflection grain storage of temperature
Whether.The thermal source of grain mainly by it is following some：Heat, grain heap are grown caused by insect caused by the respiration of grain itself
Heat etc. caused by microorganism in heat, grain heap, timely heat and moisture are exported, reduce its temperature and humidity, could be effective
Suppress grain storage to go mouldy, lose its edibility.Realize " safe, economic, effective " truly.
To be followed as shown in figure 1, this application provides a kind of silo cooling system based on intelligent control, including silo 3, gas
Loop device, spiral lever apparatus and temperature field intellectual monitoring control system, the gas-recycling plant and the upper end split-phase of silo 3
Even, a circulation loop is formed, the spiral lever apparatus includes screw rod 6 and power set 5, and power set 5 drive spiral
Bar 6 is turned clockwise, and the grain being stored in silo 3 is taken to the top of silo 3, the grain at the top of silo 3 from the bottom of silo 3
The bottom of silo 3 is slipped down under gravity, so as to which grain forms a circulation loop, the temperature field intelligence in silo 3
Monitor control system includes multiple temperature sensors 4 and the controller being arranged in silo, the gas-recycling plant and spiral
Lever apparatus is connected with controller.
It should be noted that the silo bottom is funnel-form, the temperature sensor is connected by connecting rod and silo wall
Connect, the set location and quantity of temperature sensor are depending on actual conditions.Temperature inside multiple temperature sensor collection silos
