specific Embodiment

[0027] (1), Module 1: Waste tires go through a set of intelligent fully enclosed continuous crushing and separation equipment, that is, they are cut into circles once by a ring cutter; ; After the first two stages of crushing, go through two-stage magnetic separation of belt magnetic separator and excitation magnetic separator; go through one airflow separation of airflow separator, and finally get the required 2-10mm rubber particles;

[0028] (2), module 2: without adding any chemical additives, the rubber particles of 2-10mm obtained in step (1) are fed into the screw rubber regenerator through the rubber quantitative feeder and are subjected to strong extrusion and shearing by the screw. Purely mechanical action, the sulfur-containing molecular chains are selectively broken, destroying its network structure, and realizing the green regeneration of rubber particles. Regeneration time 4-8min;

[0029] (3) Module 3: The regenerated rubber semi-finished product obtained in st...

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.

Description

technical field [0001] The invention relates to the technical field of waste rubber regeneration, in particular to an intelligent modular waste rubber continuous green sulfur-cutting regeneration complete set of technology. Background technique [0002] my country is the largest rubber consumer country in the world, but it is also a country that lacks rubber resources. At present, a large amount of waste rubber produced in China has caused serious pollution to the environment. Therefore, correct disposal of waste rubber is an inevitable choice for the circular economy to promote the scientific development of my country's rubber industry. [0003] At present, the domestic mature desulfurization regeneration technology of waste rubber is mainly based on "high temperature and high pressure dynamic desulfurization method". The product quality is good, but there are problems such as secondary pollution. Continuous desulfurization plasticizer desulfurization instead of dynamic de...
