A kind of high-efficiency continuous waste rubber regeneration equipment and preparation method

Abstract

The invention discloses a high-efficiency continuous waste rubber regeneration equipment, which comprises a high-temperature and high-speed stirring device, a constant temperature storage hopper, a first-stage constant temperature quantitative metering conveying device, a high-temperature strong shear desulfurization refining system, a second stage constant temperature quantitative metering conveying device, a low-temperature strong shear Plasticizing molding system, setting device, driving system, transmission system, cooling system, heating system and frame; the outlet of a section of constant temperature quantitative metering conveying device is connected with the inlet of thermo-mechanical chemical decoupling system; ‑Mechanochemical decoupling system includes screw, barrel, machine head, shearing teeth, and sealing gasket; the barrel is fixed on the frame, and the barrel is provided with a square hole along the circumference, and the shearing teeth are inserted into the square hole to fix, and the shearing teeth are fixed. The gap between the teeth and the barrel is sealed by a gasket, and the cutting teeth are fan-shaped. The present invention uses the cooperation between the screw flight and the shearing teeth as the shearing area, which can not only expand the shearing area, but also enhance the torsion force that the screw rod can withstand; it can decouple the mechanical shearing of high-strength vulcanized rubber particles.

Description

technical field [0001] The invention belongs to the field of reclaimed rubber preparation, and in particular relates to a high-efficiency continuous waste rubber regeneration equipment and a preparation method. Background technique [0002] With the rapid development of my country's automobile and other industries, the demand for rubber is increasing year by year. The huge demand has made my country the country with the largest rubber consumption in the world for many years. However, due to the lack of rubber resources in my country, nearly 80% of natural rubber and 60% Synthetic rubber mainly depends on imports. As a new type of rubber resource, waste rubber can alleviate the urgent shortage of rubber resources in our country if it can be used reasonably. Therefore, making good use of waste rubber, recycling it well, and turning waste into treasure has huge economic and social benefits. [0003] Reclaimed rubber is one of the main methods of recycling waste rubber. Reclai...

Problems solved by technology

However, the penetration of the activator into the waste rubber requires long-term high-temperature and high-pressure action, high energy consumption, low efficiency, and continuous production, and the long-term high-temperature oxidative cracking action increases the probability of main chain breakage, making the rubber molecular chain shorter. The quality uniformity of reclaimed rubber is poor, which is not conducive to the reuse of reclaimed rubber

In addition, because this method requires high temperature and high pressure conditions, it causes serious environmental pollution and has serious safety hazards.
