First branch airway 12, the first branch airway are equipped with multiple first gas ports, and the second wall is equipped with the be connected to the second muffler
Two main airways 21 and equipped with several the second branch airway 22 being connected to the second main airway, the second branch airway is equipped with multiple second gas
Mouthful.Second main airway, the second muffler and return line are sequentially communicated.
The main function of circulation fan is exhausting, so as to extract original air in silo out silo.Nitrogen making machine sheet
Body just has conveying capacity, can input nitrogen in silo.Nitrogen making machine coordinates circulation fan, and " one defeated one takes out " can effectively carry
Scavenging efficiency is risen, ensures nitrogen charging effect.First wall and the second wall belong to offside wall (the first wall being oppositely arranged and
Two walls), so gas integrally flows at the second wall (from the first gas port stream on each first branch airway from the first wall
Go out, the second gas port on each second branch airway entered after grain heap), it can ensure nitrogen broad covered area during nitrogen charging, nitrogen
Entire grain heap can be passed through, can also ensure that the distributing homogeneity of final nitrogen is good.
The nitrogen air inlet processed that first muffler is equipped with the second on-off valve 311 and is docked for the air inlet with nitrogen making machine
Pipe 312, nitrogen air inlet pipe processed are equipped with nitrogen on-off valve processed, and the inlet end of nitrogen air inlet pipe processed is connected to the first muffler, at first time
On the gas transmission direction of tracheae：Inlet end, the second on-off valve and the circulation fan of nitrogen air inlet pipe processed are sequentially arranged.Nitrogen air inlet pipe pair processed
Connect the air inlet of nitrogen making machine, gas outlet of the nitrogen nitrogen feeding pipe processed to nitrogen making machine).When work, the higher gas containing nitrogen concentration inside silo
Body (such as nitrogen gas concn 95%) is directly entered mobile nitrogen making machine, after nitrogen making machine " purification ", can export higher concentration
In nitrogen (such as nitrogen gas concn 99%) to silo, during so can avoid for nitrogen, nitrogen-rich gas is fed in silo always,
And gas is expelled directly out the problem of nitrogen largely wastes caused by the external world simultaneously in silo.
First wall is equipped with fan supporter, first support, second support and third holder, fan supporter and circulation
Wind turbine connects, and first support is connect with nitrogen nitrogen feeding pipe processed, and second support is connect with nitrogen air inlet pipe processed, third holder and the first return-air

The circulation fan is a centrifugal blower, and the air guide direction of circulation fan is by the first muffler to air inlet pipeline.
The nitrogen nitrogen feeding pipe processed is equipped with testing tube 5, and testing tube one end is connected to nitrogen nitrogen feeding pipe processed, and the testing tube other end is set
There is needle-valve 51.At testing tube, needle-valve nitrogen gas concn can be monitored using devices such as nitrogen gas concn detectors.
First branch airway arranges that any first branch airway is in above the first main airway vertically, and the second branch airway is perpendicular
Straight arrangement, any second branch airway are in above the second main airway.
When work, can successively utilizing different nitrogen making machines, (a fixed nitrogen making machine and a mobile nitrogen making machine, this is all
It is product in the prior art), further promoted for nitrogen effect.Nitrogen nitrogen feeding pipe processed is first docked into the gas outlet of fixed nitrogen making machine
353, the second on-off valve 311, defeated nitrogen on-off valve, discharge on-off valve 354 are opened, and the first on-off valve 351, nitrogen on-off valve processed are closed,
Gas in silo is discharged outer through the second main airway, the second muffler, return line, the first muffler, circulation fan, delivery pipe
Nitrogen is inputted silo by boundary, at the same time, nitrogen making machine by nitrogen nitrogen feeding pipe processed, air inlet pipeline and the first air inlet pipe.It waits in silo
After nitrogen gas concn reaches 95%, stops gas supply, close each valve.Fixed nitrogen making machine is unloaded, by the outlet of mobile nitrogen making machine
Mouth docks nitrogen nitrogen feeding pipe processed, and the air inlet of mobile nitrogen making machine docks nitrogen air inlet pipe 312 processed, defeated nitrogen on-off valve, nitrogen on-off valve processed
It opens, the first on-off valve 351, the second on-off valve 311, discharge on-off valve 354 are closed, and silo internal gas (contains nitrogen concentration at this time
It is higher) it is directly entered mobile nitrogen making machine, after mobile nitrogen making machine " purification ", export nitrogen (such as the nitrogen of higher concentration
Concentration 99.5%) in silo.After waiting for that concentration reaches required value (can independently set, such as nitrogen gas concn 99%) in silo, stop
It only supplies, closes each valve.The first on-off valve 351, the second on-off valve 311, circulation fan work, silo inside gas can then be opened
Body along circulation fan, air inlet pipeline, the first air inlet pipe, the first main airway, each first branch airway, grain heap, each second branch airway,
Second main airway, the second muffler, return line, the first muffler, circulation fan route recycled, cycle a period of time
Afterwards, the nitrogen gas concn of silo various places inside can reach the state being more uniformly distributed.In this operation scheme, fixed nitrogen making machine can be pre-
Good a large amount of nitrogen are first stored, nitrogen supply is directly carried out, subsequently can then be recycled for nitrogen, be carried using nitrogen making machine when movement
High nitrogen gas concn, the two combine, and N supply efficiency is high, and when can avoid only with fixed for nitrogen machine for nitrogen, nitrogen-rich gas one
Direct-furnish enters in silo, and gas is expelled directly out the problem of nitrogen largely wastes caused by the external world simultaneously in silo.
