Detailed Description

Preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings:

As shown in fig. 1, the gas storage and pressure maintaining device for nitrogen closed-loop transportation of the present invention mainly comprises an inner airbag 10 and an outer airbag 20 covering the outer portion of the inner airbag 10, wherein the inner part of the inner airbag 10 is a closed first chamber 11, and a closed second chamber 21 is formed between the inner airbag 10 and the outer airbag 20; the first chamber 11 is connected with system nitrogen, and the second chamber 21 is connected with an air outlet of the centrifugal fan 30.

The system nitrogen is nitrogen in an external storage bin 40, an annular path 41 is arranged above the storage bin 40, the first chamber 11 is connected with the annular path 41, the annular path 41 is respectively connected with a dust remover 50 and a feeding groove 60, and the dust remover 50 is connected with the feeding groove 60.

When the material enters from the feeding groove 60 and is transferred to the storage bin 40, the nitrogen originally stored in the storage bin 40 is transferred to the first chamber 11 through the annular path 41, and when the nitrogen in the first chamber 11 increases gradually, the inner bladder 10 expands due to the pressure increase, so that the pressure of the second chamber 21 also increases synchronously, and at this time, the gas in the second chamber 21 can be discharged outwards through the centrifugal fan 30, so that the pressure of the second chamber 21 reaches an allowable state. In addition, when the nitrogen originally stored in the storage bin 40 is transferred into the first chamber 11 through the annular path 41, the powder of the material mixed in the nitrogen can be recovered by the dust remover 50 and transferred into the feeding chute 60 or the storage bin 40 for recycling.

Conversely, when the material in the storage bin 40 is required to be transported, the empty space of the storage bin 40 can provide the nitrogen reflux of the system. At this time, by the reverse operation of the centrifugal fan 30,

The nitrogen of the system is stored in a chamber connected with the nitrogen; the pressure in the second chamber 21 is gradually increased to compress the inner bladder 10, so that the nitrogen in the first chamber 11 flows back to the storage bin 40 through the annular path 41.

Therefore, when the system is operated and the material in the storage bin 40 is increased through the pressure control of the centrifugal fan, the system nitrogen gas inflates the first chamber 11 of the inner air bag 10, so that the inner air bag 10 is inflated; when the contents of the storage bin 40 decrease, the inner bladder 10 will return the nitrogen stored in the first chamber 11 to the system for further use. The inner bladder 10 and the outer bladder 20 are made of soft materials including, but not limited to, polymer film, woven material or composite material. Since the inner bladder 10 and the outer bladder 20 are made of soft materials, the pressure inside and outside the inner bladder 10 can be adjusted by adjusting the pressure of the gas output or input from the centrifugal fan 30 to achieve the system pressure balance of nitrogen adjustment.

Of course, the first chamber 11 may also become connected to the outlet of the centrifugal fan 30, while the second chamber 21 becomes connected to the system nitrogen.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
