Municipal sludge combustion treatment device

The invention discloses a municipal sludge combustion treatment device which comprises a mixing hopper, a pressing hopper and a crushing hopper, and a feeding hopper is arranged above the pressing hopper; a stirring shaft is mounted in the material mixing hopper, a crushing roller is arranged in the crushing hopper, a material shaking part is further arranged on the bottom wall of a material receiving plate in the crushing hopper, and a pressing roller is mounted in the material pressing hopper; the stirring shaft can penetrate through the mixing hopper, and a driving gear is arranged on the outer side of the stirring shaft and located above the mixing hopper. According to the device, sludge and bituminous coal can be uniformly mixed together, in the process of inputting the sludge into a mixing hopper, the sludge is uniformly discharged into a pressing hopper through a feeding hopper, and then the sludge in the pressing hopper is extruded through a pressing roller, so that the caked sludge is dispersed and i
