[0027] In this embodiment, preferably, a second connection disk 302 is fixedly installed at the bottom end of the mounting cylinder 205. The second connection disk 302 is movably installed on a third connection disk 303, and a connection screw 304 is fixedly installed on the second connection disk 302.

[0028] Through the above solution, the second connection disk and the third connection disk can be connected through the connection screw, so that the mounting cylinder and the filter cylinder are installed. Moreover, the filter mesh bag can be conveniently replaced by removing the connection screw.

[0029] In this embodiment, preferably, the third connection disk 303 is fixedly installed at the top end of the filter cylinder 305. A filter mesh bag 306 is movably installed inside the filter cylinder 305, and an exhaust pipe 401 is fixedly installed at the bottom end of the filter cylinder 305.

[0030] Through the above solution, the dust in the tail gas can be filtered by the filter mesh bag, and the filtered gas in the filter cylinder can be discharged through the exhaust pipe.

[0031] In this embodiment, preferably, a second support frame 402 is fixedly installed on the outside of the filter cylinder 305, and a second fixing screw 403 is movably installed on the second support frame 402.
