The invention provides an incinerator. A rotating shaft in a stirring device, a transverse
pipe and vertical pipes are arranged inside an incinerator body; a power device and a fan are arranged outside the incinerator body; during
incineration of the incinerator body, the power device drives the rotating shaft to rotate, meanwhile, the transverse
pipe and the vertical pipes move along with rotation of the rotating shaft, and accordingly the effect of stirring materials in the incinerator body mechanically is achieved. Meanwhile, the fan is used for pumping gas into the incinerator body from the outside of the incinerator body via the rotating shaft, the transverse
pipe and the vertical pipes in sequence, and the gas is sprayed out from through holes; on the one hand, the flowing gas further stirs the materials in the incinerator body, the stirring range is extended, no stirring dead corner exists in the incinerator body, and
incineration is more uniform and sufficient; on the other hand, the temperature of the rotating shaft, the transverse pipe and the vertical pipes can be reduced through the flowing gas and is prevented from being too high in the high-temperature incinerator body,
strength reduction and deformation caused when the temperature of the rotating shaft, the transverse pipe and the vertical pipes is too high are avoided, and the service life of the incinerator is prolonged.
