Abstract

The invention discloses a green devulcanizing and reclaiming apparatus with supercritical CO2 and microwave assisted multi-segment twin-screw extrusion, comprising a horizontal barrel; a twin-screw is rotationally mounted in the barrel; the barrel is provided with a feed port at the left upper end of the twin-screw, and the upper end of the barrel is fitted ith a microwave heating device; the middle of the barrel is provided with a gas injection end for supplying supercritical CO2; the rear end of the barrel is provided with a cooling extruder, the tail end of the cooling extruder is fitted with a dicing device, and a discharge port of the dicing device is provided with a product packaging device. The apparatus of the invention has simple structure, uses small floor area, is full-automatically controllable, low in production process energy consumption and green, and the defect that traditional reclaimed rubber production process has high contamination, high energy consumption, intermittence, high labor intensity and unstable product properties is effectively solved.

Description

Technical field: [0001] The invention relates to the field of recycled rubber production equipment, in particular to a supercritical CO 2 With microwave-assisted multi-stage twin-screw extrusion green sulfur break regeneration equipment. Background technique: [0002] With the rapid development of the economy and the improvement of people's living standards, more and more cars are used. At the same time, the amount of waste tires is also increasing. A large number of waste tires have caused serious harm to the surrounding environment. The main way to deal with waste rubber (mainly waste tires) in my country is to produce recycled rubber. It has gone through a series of development processes such as oil method, water oil method, high temperature and high pressure dynamic desulfurization method, and normal pressure plasticization method. Chemical desulfurization is used to solve the defects of high pollution, high energy consumption, intermittent, high labor intensity and unst...
