Frame.
The fixed chain quantity is two, and two fixed chains are relative to the first baffle center symmetric setting.
The lifting point connects driving device.
The driving device is hoist engine or electric hoist.
Compared with prior art, its detailed description is as follows by the application：
The dust excluding hood that the application provides is U-shaped cover, and second baffle and third baffle are to be vertically arranged, and can effectively stop cigarette
Dirt it is excessive；First baffle concave towards under cambered surface, flue dust enter at the top of the dust excluding hood smoke catching passage connect it is without hindrance.
The application third baffle upper end is lived with first baffle and is hinged, and third baffle is overturn and opened by driving device, has enough
Space carry out mechanization ditch cleaning operation；Second baffle is designed with first baffle for integral type, and driving device is only needed to dust excluding hood
The baffle of one side carries out operation, reduces driving device load, and second baffle plays a supporting role first baffle；Set
Fixed chain, further plays a supporting role first baffle.
The outlet connected with smoke catching passage, realization pair are respectively provided with the first baffle and second baffle that the application provides
The efficient trapping of flue dust, and then the efficient processing realized to flue dust；Volume damper is set on smoke catching passage, is had
Effect adjusts component, ensures institute's required airflow of dedusting, and to avoiding air quantity is excessive from causing dedusting dress energy consumption excessive.
