The ceramic shell 7 can prevent the steel structure skeleton 6 from direct contact with high-temperature smoke, and prevent the steel structure from accelerated oxidation when subjected to high temperature.
[0026] An insulation layer 8 is fixedly connected to the outside of the steel structure skeleton 6, a backflow cover 9 is fixedly connected to the upper end of the steel structure skeleton 6, and a honeycomb fastening shell 10 is fixedly connected to the outer surface of the insulation layer 8. The honeycomb fastening shell 10 is composed of two quadrangular pyramidal hollow shells placed in a mirror-symmetrical manner and the two quadrangular pyramidal hollow shells are fixedly connected, and a long strip is fixedly connected to the surface of the two quadrangular pyramidal hollow shells. The overall shape of the honeycomb fastening shell 10 is a rectangular parallelepiped. The honeycomb fastening shell 10 is distributed in an array on the outside of the insulation layer 8. The honeycomb fastening shell 10 can be wrapped around the outside of the insulation layer 8, so that the noise generated by the steel structure skeleton 6 when it is heated and expanded is absorbed by the spaces in the honeycomb fastening shell 10 and reduced.
[0027] The outer surface of the honeycomb fastening shell 10 is fixedly connected to the chimney outer shell 1, and the inner side of the guide shell 5 is fixedly connected to the positioning friction disk 11. The inner side of the guide shell 5 is fixedly connected to an eccentric motor 12, and the output end of the eccentric motor 12 is fixedly connected to an eccentric disk 13. The upper surface of the eccentric disk 13 is fixedly connected to a traction line 14. The eccentric disk 13 can drive the traction line 14 to rotate by rotating, and the eccentric connection between the eccentric disk 13 and the traction line 14 is utilized so that the rotation of the eccentric disk 13 can intermittently pull the traction line 14, and the traction line 14 passes through the positioning friction disk 11.

[0031] Working principle: When in use, when smoke enters from the inlet pipe 2 and reaches the connecting head 4, the eccentric motor 12 is started to drive the eccentric disk 13 to rotate, so that the eccentric disk 13 drives the traction line 14 to rotate, so that the traction line 14 is pulled inside the positioning friction disk 11, and the air-blowing shell 15 is pulled by the traction line 14. The reset spring 16 is used to make the air-blowing shell 15 bounce up and down to blow out the air flow from the inside of the conical shell 17 to guide the smoke to move upward. By opening a through hole at the lower end of the guide shell 5, air enters from the bottom and enters along the circular hole of the positioning friction disk 11 to replenish the air for the air-blowing shell 15 in time. The backflow cover 9 is installed at the upper end to prevent the upper air flow and rainwater from entering.
