[0029] Multiple outlets are provided at the lower part of the housing 11 on one side of the filter screen 14. The housing 11 at the outlet is rotatably connected to a buckle 18, which fixes the collection tank 19 after being rotatably connected.

[0030] An air pipe 20 is provided on the housing 11 on both sides of a partition 12, and an air pump 21 is provided on the air pipe 20.

[0031] Working process: The film core is a hollow roll. One end of the film core is fixed to the second fixed post 5 near the fixed ring 8.
