Smoke dust continuous extrusion granulation device

The invention provides a smoke dust continuous extrusion granulation device which comprises a granulation processing box, a feeding port is formed in the upper end of the granulation processing box, a discharging port is formed in the lower end of the granulation processing box, an extrusion granulation assembly is arranged on the inner wall of the granulation processing box, and the extrusion granulation assembly comprises two extrusion roller bodies. A preset gap is formed between the two extrusion roller bodies to form a discharging channel, a plurality of granulation grooves arranged in an array mode are formed in the surfaces of the extrusion roller bodies, first driving rotating shafts are fixedly connected to the axes of the extrusion roller bodies, and a driving assembly is arranged on the outer side of the granulation processing box and used for controlling the two first driving rotating shafts to rotate synchronously. And two groups of cleaning assemblies are arranged in the granulation processing b
