After the filter screen filters the recovered helium, there are impurities in the filter holes. The filter holes are cleaned by the moving cleaning plate brush 17, so that the filtering efficiency will not be reduced.

[0029] The motor 2 drives the No. 1 rotating shaft 3 to rotate, and then drives the exhaust fan blades 19 to rotate. When a leakage problem occurs at the input end of the tank body 1, the rotating exhaust fan blades 19 will extract the leaked helium, and then the extracted helium will be absorbed by the molecular sieve in the shell 18, thereby improving the safety of the operation and ensuring the personal safety of the staff.
