Description
One, technical field
The utility model relates to a kind of auxiliary equipment of grain storage silo, and checkout gear outside the silo nitrogen gas concn storehouse that the nitrogen technology carries out grain storage is filled in specifically a kind of utilization.
Two, background technology
In order to satisfy people's craving for to pollution-free food, at the beginning of 21 century, FAO (Food and Agriculture Organization of the United Nation) will further limit and forbid the use of fumigant in the grain and oil grain storage process, and actively advocate to regulate the gas ingredients in the grain heap, be air-conditioning storing grain, change the living environment of insect, mould, reduce the aerobic respiration of grain self, reach stored grain safety, delay aging, realize green grain storage purpose.
The air-conditioning storing grain of present domestic employing mainly contains dual mode, and a kind of is that its killing pests and suppressing bacteria effect is better with the air in the carbon dioxide direct replacement grain heap.But carbon dioxide grain storage expense is bigger, and has water-soluble and corrosivity, is a kind of gas that can produce greenhouse effects, and atmosphere, human body are had certain detrimental effect.Another kind is a nitrogen filling grain storage, because nitrogen shows as inertia in chemical reaction, character is more stable, and is pollution-free to atmosphere, and the staff is not had injury, and CO is compared in no critical value requirement under equal volume
2Cheap, the energy killing pests and suppressing bacteria is guaranteed the safety of storing up grain equally, delays grain ageing.When using nitrogen filling grain storage, adopt environmental protection transformation absorption sieve nitrogen-rich store grain machine, be connected with silo by surge tank, gas temperature adjuster, nitrogen can directly be pressed into the grain heap through nitrogen-rich store grain machine, through the rich nitrogen deoxygenation of malleation, makes the N of grain heap
2Content reaches requirement, thereby realizes the purpose of nitrogen filling grain storage.
During nitrogen filling grain storage, the content of nitrogen in the silo there is strict demand.It is to be raw material with the air that grain is piled rich nitrogen insecticidal technology, utilize empty branch technology to isolate nitrogen, through return air network under the film nitrogen of concentration more than 99% is charged into the grain heap, change grain heap gas componant structure, the interior oxygen concentration of grain heap is dropped to below 5%, nitrogen gas concn is elevated to more than 96%, thereby reaches anoxic desinsection and grain storage purpose.Because be full of nitrogen in the silo, operating personnel enter the detection of carrying out nitrogen gas concn in the silo, not only dangerous, detection time is long, and labour intensity is big, and to the damage that causes of film, has reduced air-tightness.This just requires a kind of equipment that can carry out the nitrogen gas concn detection outside silo.
Three, summary of the invention
In order to address the above problem, the purpose of this utility model provides checkout gear outside a kind of silo nitrogen gas concn storehouse, can accurately measure nitrogen gas concn in the silo by this detector outside silo.
The purpose of this utility model is achieved through the following technical solutions:
Checkout gear outside a kind of silo nitrogen gas concn storehouse, it is characterized in that: it comprises wireway, control valve group and nitrogen gas concn detector, one end of wireway be embedded in the silo inner membrance under air receiver in the grain heap communicate, the other end of wireway is connected with the nitrogen gas concn detector by the control valve group; The gas concentration detector that is used for measuring nitrogen gas concn is arranged on outside the silo.
For accurately measuring in the silo nitrogen gas concn everywhere, the quantity of wireway described in the utility model is with to be embedded under the film air receiver quantity and the position in the grain heap suitable.Air receiver is embedded in grain usually and piles four jiaos and middle position.
Be provided with in the described control valve group and the suitable gas outlet of the quantity of wireway, be equipped with control valve, control the output of nitrogen everywhere in the silo by each control valve at each place, gas outlet.
For detecting in the silo nitrogen gas concn everywhere respectively, be provided with at the nitrogen gas concn detector and get air valve, get air valve and be used for controlling being connected of each measurement point wireway and gas concentration detector and close.Need to measure the nitrogen gas concn of a certain position, just the air valve of getting on the gas outlet that will locate and the nitrogen gas concn detector is connected, and other gas outlet then is in closed condition.
For conveniently obtaining data, on gas concentration detector, be provided with and be used for showing nitrogen gas concn numerical value crystal screen.During detection, opening power, behind the connection wireway, 10 seconds inherent panel liquid crystal screens of nitrogen gas concn are gone up accurately and are shown.
The utility model is opened by each control valve control in the outer control valve group of silo outside everywhere the nitrogen output storehouse in the silo, connects gas concentration detector.The utility model is safe and reliable, has shortened detection time, has strengthened operating personnel's safeguard protection when alleviating labor intensity of operating staff; And stopped to have guaranteed air-tightness because of detecting damage in the storehouse to film.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment
Checkout gear outside a kind of silo nitrogen gas concn described in the utility model storehouse, it comprises one group of wireway 1, control valve group 2 and nitrogen gas concn detector 3, one end of wireway 1 be embedded in the silo inner membrance under air receiver 4 in the grain heap communicate, the other end of wireway 2 is connected with nitrogen gas concn detector 3 by control valve group 2; The nitrogen gas concn detector 3 that is used for measuring nitrogen gas concn is arranged on outside the silo.For accurately measuring in the silo nitrogen gas concn everywhere, the quantity of wireway 2 is with to be embedded under the film air receiver 4 quantity and the position in the grain heap suitable, and air receiver 4 is embedded in grain usually and piles four jiaos and middle position.
For detecting separately in the silo nitrogen gas concn everywhere, be provided with the gas outlet 21 suitable in the control valve group 2 outside silo with the quantity of wireway 1, be equipped with control valve at each 21 place, gas outlet, control the output of nitrogen everywhere in the silo by each control valve.Control valve group 2 can be fixed on the outer wall of silo.
Be provided with at the nitrogen gas concn detector and get air valve 31, get air valve 31 and be used for controlling being connected of each measurement point wireway 1 and nitrogen gas concn detector 3 and close.Need to measure the nitrogen gas concn of a certain position, just the wireway that will locate and gas concentration detector are connected, and other wireway then is in closed condition.
