Abstract
The invention discloses an intelligent modularized continuous green devulcanizing and regenerating complete technology for waste rubber. A waste rtyre passes through intelligent fully-sealed type continuous crushing and separating equipment to carry out primary ring-cutting, tertiary crushing, secondary magnetic separating and primary airflow classifying to finally obtain required rubber particles; under the condition of not adding any chemical auxiliary agent, the rubber particles are fed into a screw rubber regenerator through a rubber quantitative feeder for being subjected to screw extrusion-shearing pure mechanical action, so that sulfur-containing molecular chains are selectively broken to break network structures of the sulfur-containing molecular chains, and therefore, green devulcanizing and regenerating of the rubber particles is realized; then, regenerated rubber enters intelligent filter equipment for filtering large particles, impurities and the like after being subjected to preliminary cooling; and finally, particle-shaped regenerated rubber is packed and stored after being waxed, cooled and dried. The intelligent modularized continuous green devulcanizing and regenerating complete technology for waste rubber disclosed by the invention realizes green, energy-saving, continuous, intelligent, efficient and safe production of the whole process from the waste tyre to particle-shaped regenerated rubber.
