Hearth vacuum type air cleaning cap dust suction device

The utility model belongs to the technical field of industrial furnace dust collection devices. The utility model relates to a dust collector, in particular to a hearth vacuum air-cleaning cap dust collector. Including a base, connecting frames are fixedly connected to the tops of the outer side walls of the base; the furnace body is arranged between the two connecting frames; the dust collectionmechanism is arranged at the bottom of the outer side wall of the furnace body; the microcontroller is mounted on the outer side wall of the connecting frame on the right side; the conveyor is fixedlyconnected to the top of the outer side wall of the base. The dust collection fan is started through the microcontroller; slag is sucked into the dust collection fan through the air inlet pipe; due tosudden expansion of the section of the airflow and multiple effects of spoilers or cyclones, the airflow is more uniform; part of coarse slag in airflow directly settles into the ash bucket, an outlet of the dust suction fan i
