The liquid tank 2 is used to seal the connection between the main body connection cover of the storage container and the upper opening of the storage area 3, and the connection between the air flow pipeline of the storage container and the first distribution pipeline 301 and the second distribution pipeline 302.
Wherein, the storage containers are stacked on the liquid tank 2, and the inner cavities of the storage containers form storage units; the air flow pipeline of the storage container comprises a first connecting pipe and a second connecting pipe, wherein the first connecting pipe and the second connecting pipe are respectively arranged on a first distribution pipeline 301 and a second distribution pipeline 302 to form an air flow passage; wherein, the side wall of the first connecting pipe is provided with a connecting branch pipe which is communicated with the first connecting pipe and the inner cavity of the storage container; and the side wall of the storage container is provided with a liquid groove so as to provide a liquid sealing condition.
When two or more storage containers 9 are stacked, the main body connection cover 905 of the upper storage container 9 extends into the liquid tank 904 of the lower storage container 9 to enable the inner cavities of the two or more stacked storage containers 9 to be communicated, wherein the first connection pipe 901 of the upper storage container 9 extends into the liquid tank 904 of the lower storage container 9 through the pipeline connection cover 906, the lower end of the first connection pipe 901 of the upper storage container 9 is liquid-sealed with the upper end of the second connection pipe 902 of the lower storage container 9, and similarly, the second connection pipe 902 of the upper storage container 9 extends into the liquid tank 904 of the lower storage container 9 through the pipeline connection cover 906, and the lower end of the second connection pipe 902 of the upper storage container 9 is liquid-sealed with the upper end of the first connection pipe 901 of the lower storage container 9.
The pipe connection cover 906 of the storage container 9 at the bottom is extended into the liquid tank 2, and the first connection pipe 901 and the second connection pipe 902 are liquid-sealed with the ends of the first distribution pipe 301 and the second distribution pipe 302, respectively.
Since the shape of the body connecting cover 905 at the lower end of the upper storage container 9 after rotating 180 degrees corresponds to the shape of the opening at the upper end of the lower storage container 9, the first connecting pipe 901 and the second connecting pipe 902 are centrally symmetrical on the storage container 9, the upper storage container 9 is stacked on the lower storage container (9) by rotating 180 degrees relative to the lower storage container 9 through the upper storage container 9, the body connecting cover 905 of the upper storage container (9) and the opening at the upper end of the lower storage container (9) can be matched to form a liquid seal, and the first connecting pipe 901 and the second connecting pipe 902 at both sides of the storage container 9 are alternately communicated through the liquid seal to form independent air flow passages.
And 3, stacking the top of the storage container for liquid seal, and mounting the check valve 7, the capping liquid seal cover 4 and the air pipe liquid seal cover 6 on the top of the top storage container 9 to ensure that the top of the storage container 9 is liquid sealed with a storage system.
Wherein the check valve 7, the capping liquid enclosure 4, the tracheal liquid enclosure 6 are mounted to the top of the top storage container 9 such that the top of the storage container 9 is liquid tight. This liquid seal is the same principle as a storage system comprising only a storage area 3.
Specifically, the liquid seal mode of the top of the storage container 9 is as follows: the inner end opening of the check valve 7 is connected to the end opening of the second connecting pipe 902, the capping liquid sealing cover 4 is stretched into the liquid groove 904 to perform liquid sealing on the outer end opening of the check valve 7 on the second connecting pipe 902 of the top storage container 9 and the upper end opening of the top storage container 9, an air passage is left between the upper end opening of the liquid-sealed storage container 9 and the outer end opening of the check valve 7, so that the gas output by the second connecting pipe 902 of the top storage container 9 can stably enter and exit the top storage container 9, and the gas pipe liquid sealing cover 6 is stretched into the liquid groove 904 to perform liquid sealing on the upper end opening of the first connecting pipe 901 of the top storage container 9.

At this time, the gas supplied from the second connection pipe 902 of the a storage container enters the inner cavity of the a storage container through the check valve 7, and the gas in the inside of the a storage container is discharged from the connection branch pipe 903 of the a storage container, thereby achieving quick precooling or gas conditioning of the a storage container.
When there is a storage container above the a storage container, in which the second connection pipe 902 of the top storage container needs to be set to return air, the control valves 907 of the connection branch 903 of the a storage container and the connection branch 903 of the storage container above the a storage container are opened, and the control valves 907 of the connection branches 903 of the remaining storage containers are closed.
At this time, if the first connection pipe 901 of the a storage container is blowing, the gas delivered from the connection branch pipe 903 of the a storage container is delivered to the inner cavity of the a storage container, and the gas in the inner cavity of the a storage container is discharged through the connection branch pipe 903 of the upper storage container, thereby realizing rapid precooling or gas conditioning of the a storage container.
At this time, if the first connection pipe 901 of the a storage container is ventilated, gas is supplied into the inner chamber of the a storage container through the connection branch pipe 903 of the upper storage container, and gas in the inner chamber of the a storage container is discharged through the connection branch pipe 903 of the a storage container, thereby achieving rapid precooling or atmosphere control of the a storage container.
