[0038] A connecting pipe 7 is embedded and fixed on the top end surface of the bag dust collector 5 .

[0039] Both ends of the outer surface of the shell 6 are welded with connecting blocks 8, and the end of the connecting block 8 facing away from the shell 6 is welded to the fixing frame 13, and the shell 6 can be installed and fixed on the fixing frame 13 through the connecting block 8.

[0040] Both ends of the outer surface of the shell 2 4 are welded with connecting blocks 2 11 , and the end of the connecting block 2 11 away from the shell 2 4 is welded to the fixing frame 13 , and the shell 2 4 can be installed and fixed on the fixing frame 13 through the connecting block 2 11 .
