Rotary dryer stove with dust removal function

The utility model provides a rotary dryer stove with dust removal function, including the barrel being close to the gas outlet on the inner wall of barrel and setting up the lifting blade, the lifting blade is arranged along the circumferencial direction of barrel, and still sets up the spiral plate in the inner wall of barrel has the region of lifting blade, the raw materials coal is when removing near the gas outlet like this, fully kicked up by the lifting blade in region through being provided with the lifting blade, barrel internal heat flue gas is velocity of flow increase through the spiral plate time, it separates with the coal cinder in the hot flue gas of the suitable velocity of flow to make granule footpath fine coal in the raw materials coal swept along, thereby realized that the rotary dryer stove is when carrying out the drying to the raw materials coal, the also granule footpath granule of furthest in with the raw materials coal effect of detaching, the dust disposal volume of coal in matter process is carried in follow -up dry distillation has greatly been reduced.
