Waste rubber desulfurization plasticizing device

Abstract

The invention particularly relates to a waste rubber desulfurization plasticizing device, which belongs to the technical field of waste rubber regeneration equipment. The waste rubber desulfurization plasticizing device comprises a storage bin which is connected with a plasticizing pipeline; the tail end of the plasticizing pipeline is connected with a cooling pipeline; a discharge port is arranged at the tail end of the cooling pipeline; a spiral feeding manner is adopted in the plasticizing pipeline and the cooling pipeline; the surface of the plasticizing pipeline is provided with a heating device; the inner wall of the plasticizing pipeline is uniformly provided with pin bolts; the tail end of the plasticizing pipeline is provided with an extruding device; a motor-driven shearing device is arranged at the joint of the plasticizing pipeline and the cooling pipeline. The waste rubber desulfurization plasticizing device can be used for recycling waste rubber to avoid pollution and achieve environmental protection, is safe in use, and realizes high yield with low energy consumption; moreover, the waste rubber conversion rate is high, and regenerated rubber is high in quality; the space occupation ratio is low, and thus the space is saved; the operation is simple, and thus labor is saved; in addition, the manufacturing cost is low, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of waste rubber regeneration equipment, in particular to a waste rubber desulfurization and plasticization device. Background technique [0002] As an important strategic material, rubber is strictly controlled by all countries. my country is a country that uses a lot of rubber, but also a country that is extremely scarce in rubber resources and produces a lot of waste rubber. About 70% of the annual rubber consumption is imported from abroad. China's General Administration of Customs announced that my country imported 2.18 million tons of natural rubber in 2012, which was 3.8% higher than the 2.1 million tons in 2011. Therefore, the reuse and reproduction of waste rubber has far-reaching significance for my country to get rid of the plight of lack of rubber resources. In order to solve the shortage of rubber resources in our country, our country has been advocating, encouraging and supporting the recycli...

Problems solved by technology

At present, dynamic desulfurization tanks and automatic rubber powder plasticization devices are basically used in China, and dynamic desulfurization tanks are the main ones. The main disadvantages are as follows: 1. Secondary pollution: the dynamic desulfurization process must be added A certain proportion of water, water and regenerant react under high temperature conditions to produce a large amount of organic gas. Although the waste gas has been treated, the problem of secondary pollution cannot be fundamentally solved at present; 2. Poor safety: the current work of dynamic desulfurization process The pressure is from 1.6 to 4.0.ZMPa and H-type pressure vessels are required. Long-term use will cause the tank wall to become thinner and cause safety hazards. Once improper operation will cause equipment and personal accidents; 3. High energy consumption: due to the thick tank wall, the heat transfer speed Slow, low efficiency, high energy consumption; 4. Unstable quality: Due to the large tank body, the stirring speed is slow, the stirring is uneven, and the scaling of the tank wall over time causes poor control of the process and uneven quality of the desulfurized rubber. Large fluctuations and instability, easy to block the material and stick the screw, break the refining wheel, the equipment is not durable, and the equipment manufacturing cost is high
