[0044] Specifically, the rubber ring 16 makes it easier to protect the rear end of the outer wall of the extraction pipe 6, thereby reducing its wear. The connecting plate 19 and the support column 20 make the device more stable during operation.

[0045] Working principle: When the gas distribution work starts, the liquid raw material is introduced into the storage tank 4 through the feed valve 5, and the low-temperature storage device 3 is turned on so that the storage tank 4 can be low-temperature stored.
