Device for automatically recycling and blending carbon black discharged and dedusted on mixing line

The utility model discloses a mixing line unloading dust removal carbon black automatic recycling and blending device in the field of internal mixers, which comprises an internal mixer and a dust remover, a feeding pipe is arranged above the internal mixer, a discharging pipe is arranged on one side below the internal mixer, and a feeding dust suction pipe is arranged above the feeding pipe. The feeding dust extraction pipe and the discharging dust extraction pipe are combined and then connected with the dust remover for dust removal, the carbon black recovery cost can be saved, meanwhile, the dust extraction force after the feeding dust extraction pipe and the discharging dust extraction pipe are combined can be measured in real time through the main path pressure difference transmitter, and the dust extraction efficiency is improved. The ventilation quantity in the material discharging and dust sucking pipe is controlled through the adjusting air door, and the adjusting air door is matched with the branch p
