Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, the utility model provides a plant feed bin security system, including feed bin 1, and the feed bin 1 pushes up
End is equipped with feed bin lid 2, and several material pressure tables 3, the detector position of material pressure table 3 are equipped on the side wall of the feed bin 1
Inside feed bin 1, pressure value shows the outside of end movement feed bin 1, is more conducive to the observation to material pressure, material pressure
Table 3 can show the material pressure inside feed bin 1, can also detect gas pressure when hole capital after selling all securities.
The left and right side of the bottom end of the feed bin 1 is separately installed with relief tube 4 and safety valve 5, and relief tube 4 can be in feed bin
In 1 material pressure be above standard value when reduce material pressure, to keep storing material more preferable, the material pressure in storehouse of safety valve 5
Power can automatically turn on when excessive, to make extra material be flowed out from the gap that safety valve 5 is opened, prevent material to feed bin 1
Pressure is excessive and influences the service life of feed bin 1.
Control valve 10 is installed, the bottom end of relief tube 4 inclined downward to the left is aobvious in material pressure table 3 on the relief tube 4
Show the material pressure in feed bin 1 be above standard pressure value when, operating personnel open out the object that control valve 10 keeps pressure excessive manually
Material flows out a part, when 3 pressure of material pressure table reaches standard value, closing control valve 10 from relief tube 4.
Preferably, the pressure in feed bin 1 is made to remain standard value, feed bin by the design of relief tube 4 and safety valve 5
1 will not damage, storing material better quality.
Laser material position device 6 and air pressure detection pipe 7 are installed, 1 bottom end of the feed bin is connected with outlet on the feed bin lid 2

One-way vent valve 71 includes the valve housing 74 being fixed on feed bin lid 2, and the bottom end and top inside the valve housing 74 are set respectively
There are gas communication hole 75 and round platform slot 76, round platform sealing block 77,77 bottom of round platform sealing block are inserted in the round platform slot 76
End is connected by spring 78 with the bottom surface of round platform slot 76.
The ventilation principle of one-way vent valve 71：Under normal circumstances, under the effect of the elastic force of spring 78, round platform sealing block 77
Side and the side of round platform slot 76 are tightly affixed, in feed bin 1 will not gas leakage, be passed through height into feed bin 1 using air pressure detection pipe 7
Calm the anger body when, the pressure of gas makes spring 78 compress, and round platform sealing block 77 is to bottom offset, the side of round platform sealing block 77 and round platform
Gap is generated between the side of slot 76, high pressure gas enters inside feed bin 1, after enough high pressure gas enter hasty and careless 1 inside, stops
Only to being passed through high pressure gas in feed bin 1, at this moment in round platform sealing block 77 in storehouse the pressure of high pressure gas and spring 78 it is dual
It is shifted up under active force, round platform sealing block 77 again blocks stomata, to make gas not reveal.
The step of detecting the air-tightness inside feed bin 1 by air pressure detection pipe 7 is as follows：
(1) ensure that 1 inside of feed bin does not have material before detection, then all valves and hydraulic control device are in closing shape
Then air pressure detection pipe 7 is connected by state with the efferent duct that high pressure gas pumps, high pressure gas starts to enter from air pressure detection pipe 7
Inside feed bin 1, after suitable high pressure gas is passed through into storehouse, the connection of air pressure detection pipe 7 and high pressure gas pump is disconnected, unidirectionally
Breather valve 71 is automatically closed, and at this moment observes the numerical value of material pressure table 3；
(2) it waits for 10-20 minutes, observes the pressure value on material pressure table 3 again, compare the difference of front and back pressure value
It is different, its error is calculated whether in critical field, if the two pressure value difference is too big, illustrates that 1 inside air-tightness of feed bin is inadequate,
Part to feed bin 1 and thereon is needed to carry out air-leakage test；
(3) after detecting, escape pipe 72 is connected using vacuum pump or gas suction pump, and open air valve 73, at this moment
High pressure gas in storehouse can be discharged.
Preferably, the design of air pressure detection pipe 7 and one-way vent valve 71 keeps the air-leakage test inside feed bin 1 more square
Just quick, manpower is saved, the air-leakage test inside feed bin 1 also shows ability and the longevity of the storage material of feed bin 1 indirectly
Life stores the serious conditions such as material time short, the compression cracking of feed bin 1 so as to avoid feed bin 1.
