Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. The features and advantages of the present invention will become more apparent from the description. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them.

As shown in fig. 1-3, the high temperature resistant telescopic flue gas hood of this embodiment includes a fixed hood body 1 and a plurality of sections of sequentially telescopically assembled movable hood bodies, in this embodiment, the movable hood bodies include a movable hood body a3, a movable hood body B4 and a movable hood body C5, which are sequentially telescopically assembled; the fixed cover body 1 is welded and fixed with the ground embedded part. The movable cover body A3 is telescopically assembled with the fixed cover body 1, the rear end and the top of the fixed cover body are both provided with air outlets 12 communicated with a dust removal pipeline, and the top of the air inlet side is provided with an air supply air curtain device 6; when the telescopic hood works, a workpiece is cut in the telescopic hood, air supply air flow is generated through the air supply air curtain device, suction air flow is generated through the air outlet, high-temperature smoke generated by cutting is timely sucked away under the action of the suction air flow, and a clean working environment is created for workers.
