The utility model relates to the technical field of
incineration devices of rotary kilns, in particular to a high-efficiency
incineration device of a
rotary kiln, which is provided with a feed hopper capable of moving up and down, a stirring rod with a
cutting blade, a movable separation inner
barrel and a movable separation outer
barrel, so that materials can be fully pretreated, and large-size materials can be
cut up by the
cutting blade; the materials are pushed to move, so that the problems of non-uniform heating and incomplete
combustion in the
rotary kiln caused by overlarge size or
caking of the materials are prevented, and the
incineration efficiency is improved; a first motor and a push rod in the driving mechanism are matched with a transmission plate and a balancing weight on a stirring rod, so that the stirring rod can move up and down, the stirring and
cutting effects on the materials in the feeding hopper are further enhanced, the materials are mixed more uniformly, pretreatment is more sufficient, meanwhile, the materials in the feeding hopper and the rotating inner
barrel vibrate up and down, and the stirring efficiency is improved. And the
cut granular materials are separated out.
