Reverse hot air conveying roller based on coal drying treatment

Abstract

The utility model discloses a coal drying treatment-based roller for reverse hot air delivery, which comprises a feeding mechanism and a drying roller mechanism, the feeding mechanism is arranged on one side of the drying roller mechanism, a cooling roller mechanism is arranged on the other side of the drying roller mechanism, a feeding connecting pipe is arranged at the side end of the top of the feeding mechanism, and the cooling roller mechanism is arranged on the side end of the top of the feeding mechanism. The end, away from the feeding mechanism, of the feeding connecting pipe is sleeved with the middle of the end of the drying roller mechanism, the end, away from the feeding connecting pipe, of the drying roller mechanism is sleeved with a hot air pipe, the end, away from the drying roller mechanism, of the hot air pipe is fixedly sleeved with a double-layer heating bin, and two flamethrowers are arranged on the side face, away from the hot air pipe, of the double-layer heating bin. The drying roller mechanism, the double-layer heating bin, the flame projector and other structures work cooperatively. And the wet coal is uniformly dispersed under the action of the lifting plate and moves towards the hot air pipe. The flamethrower combusts in the internal combustion bin to generate heat, hot air reversely flows into the roller through the hot air pipe to form reverse heat exchange with wet coal, the heat energy utilization rate is increased, and deep dehydration is achieved.
