[0003] The existing solid waste pyrolysis treatment device usually directly pyrolyzes the untreated solid waste, but the particle size of the material has great difference. These solid wastes of different sizes not only reduce the processing efficiency of the pyrolysis treatment device, but also affect the quality and yield of the pyrolysis products after entering the pyrolysis device. Moreover, there is a lack of mixing operation of the material, which leads to uneven distribution of the material in the pyrolysis container.
