Description
Technical field
The present invention relates to storage warehouse nitrogen-charging fresh-keeping technology, especially relate to a kind of storage storehouse inflated with nitrogen and adjust fresh-keeping intelligent control system.
Background technology
It is in warehouse or container, be filled with appropriate nitrogen-rich gas in confined conditions that inflated with nitrogen is adjusted, and the oxygen in warehouse or in container efficiently, is rapidly cemented out, make in warehouse or be in the method for hypoxemia or anoxybiotic state in container for a long time, this technology is mainly used in the reserves such as grain, fruits and vegetables, local products, medicinal material, books archives.After the reserves such as grain are filled with nitrogen-rich gas, be in for a long time hypoxemia or anoxybiotic state storage can desinsection, insect protected, again can anti-bacteria breeding, the ageing of delay grain quality; Fruits and vegetables inflated with nitrogen can delay the fruits and vegetables shelf-life, can keep freshness again after adjusting.Carry out inflated with nitrogen timing, due to airing form, fill the quality that the factors such as nitrogen quantity, air capacity, air compensation, circulation directly affect ca cold storage fresh-keeping effect, therefore how carry out inflated with nitrogen timing at storage storehouse efficiently and realize nitrogen-oxygen conversion efficiently and to seem particular importance.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rational in infrastructure, easy to operate, and nitrogen-oxygen conversion efficiency is high, and the storage storehouse inflated with nitrogen that cost is low, nitrogen concentration ascending velocity is fast in storehouse adjusts fresh-keeping intelligent control system.
The present invention is achieved through the following technical solutions:
A kind of storage storehouse inflated with nitrogen adjusts fresh-keeping intelligent control system, comprise circulating pipe, draft tube in circulation fan, storehouse, it is characterized in that: draft tube is connected with upper inlet valve, lower inlet valve by flange, bolt, ventilating opening is connected with ventilating opening intake air release valve respectively by storehouse outside circulation pipe, pipe break valve by pipeline, flange, bolt respectively with circulation fan, ventilating opening intake air release valve, on be charged into circulating pipe in air valve, storehouse and be connected, form a complete nitrogen-oxygen modular converter; Nitrogen-oxygen modular converter, sensor assembly, each electrically operated valve are connected with PLC control unit in a wired fashion, control computer and are controlled the opening of each electrically operated valve by wireless or wired mode control PLC control module, closed.
By controlling to be arranged on the opening of each electrically operated valve on stainless steel pipes, closing, and automatically can start or stop inflation according to pressure in warehouse and oxygen concentration data, selection is filled lower row, under the row of filling with, fill while arrange, on fill, airing form, exhaust mode, circulating current system that lower charge, exhaust circulation is different, realize adjusting the inflated with nitrogen in different material warehouse, nitrogen gas concn balance, displace oxygen.Thus reach the object reducing space oxygen concentration in storehouse, improve space nitrogen gas concn in storehouse.
This system architecture is reasonable, and easy to operate, nitrogen-oxygen conversion efficiency is high, and cost is low, nitrogen concentration ascending velocity is fast in storehouse, and automaticity is high.The storages such as suitable grain, fruits and vegetables, local products, medicinal material, books archives.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 for control computer, 2 be PLC control unit, 3 be on be charged into air valve; 4 be under be charged into air valve; 5 is vent valve; 6 is A ventilating opening intake air release valve, and 7 is B ventilating opening intake air release valve, and 8 is C ventilating opening intake air release valve, and 9 is stop valve, and 10 is circulation fan, and 11 is circulating pipe in storehouse, and 12 is storehouse outside circulation pipe, and 13 is draft tube.
Embodiment
The present invention will be further described with accompanying drawing with the following Examples:
As shown in Figure 1, the present embodiment establishes the storage storehouse inflated with nitrogen of A, B, C tri-ventilating openings to adjust fresh-keeping intelligent control system, can arrange 1-6 ventilating opening according to storehouse size.By draft tube 13 by flange, bolt with on be charged into air valve 3, under be charged into air valve 4 and be connected, A, B, C ventilating opening is connected with A ventilating opening intake air release valve 6, B ventilating opening intake air release valve 7, C ventilating opening intake air release valve 8 respectively by storehouse outside circulation pipe 12, flange, bolt, stop valve 9 by pipeline, flange, bolt respectively with circulation fan 10, ventilating opening intake air release valve 6, ventilating opening intake air release valve 7, ventilating opening intake air release valve 8, on be charged into circulating pipe 11 in air valve 3, storehouse and be connected, form a complete nitrogen-oxygen modular converter; Each electrically operated valve is connected with PLC control unit 2 in a wired fashion, controls computer 1 and controlled by wireless or wired mode.Valve module group can accept main control computer and carry out Valve controlling, and handle also can be used to carry out Non-follow control, realizes module group automatic/hand and runs.
Sensor assembly comprises pressure transducer and oxygen concentration sensor, and pressure transducer is placed in space in storehouse by a PVC tube at one end Bonding pressure sensor other end, for measure in storehouse because of nitrogen numbers increase or reduce pressure value; Oxygen concentration sensor is positioned over different parts in storehouse, for measuring each point oxygen density value in storehouse.Pressure transducer is connected with the analog quantity modular converter of PLC with oxygen concentration sensor, and pressure in the storehouse that detection obtains and oxygen concentration data are uploaded to main control computer computer by wireless or wired mode, for intelligent control system provides decision-making foundation.
When electrically operated valve is used for connecting and blocking pipeline, nitrogen-oxygen is passed through or ends passing through of nitrogen-oxygen.Circulation fan is used for nitrogen-oxygen in the circulation of the inner nitrogen-oxygen in warehouse or storehouse and discharges, and pipeline is used for inflating in storehouse, outwards exhaust or gas circulating.
PLC control unit controls to be arranged on the opening of each electrically operated valve on nitrogen-oxygen modular converter, closes, and automatically can start or stop inflation according to pressure in warehouse and oxygen concentration data, by select to fill lower row, under the row of filling with, fill while arrange, on fill, airing form, exhaust mode, circulating current system that lower charge, exhaust circulation etc. is different, thus realize adjusting the inflated with nitrogen in different material warehouse, and the nitrogen gas concn in space in storehouse can be made to balance.By the replacement of oxygen in space in storehouse out, thus reach the object reducing space oxygen concentration in storehouse, improve space nitrogen gas concn in storehouse.
