[0026] An air inlet 11 is installed on the upper side of the dust removal tower 1, and a valve is installed inside the air inlet 11.

[0027] The top of the dust removal tower 1 is connected to an exhaust port 10. A hollow ring plate 20 is fixed to the inner wall of the exhaust port 10. An installation ring 21 is mounted on the hollow ring plate 20. The hollow ring plate 20 and the installation ring 21 are connected and assembled by connecting bolts 22.

[0028] A filter screen 23 is fixed inside the mounting ring 21, and connecting bolts 22 are distributed in a ring between the mounting ring 21 and the hollow ring plate 20.
