Waste rubber low-temperature regeneration equipment

Abstract

The invention belongs to the technical field of waste rubber recovery processing equipment, and specifically relates to waste rubber low-temperature regeneration equipment. A main body structure comprises a rubber powder material cabin, a No.1 spiral feeding machine, a high-low speed premixing stirring machine, a No.2 spiral feeding machine, a feeding machine, a desulfurization machine, a coolingbuffer cabin, an extrusion machine, a cooling water spraying pipe, a water filtering opening, an exhaust opening, a No.1 waste gas collecting pipe, a No.2 waste gas collecting pipe, a high-pressure gear pump, a discharging opening and a warm mold machine. Under the low-temperature condition, the regeneration rubber production is performed on the basis of a high-shearing rotor and the high-pressuregear pump; the rubber material formed by mixing rubber powder and a regeneration agent is added into the desulfurization machine through the feeding machine; the rubber powder performs shearing and desulfurization and plastification regeneration under the mechanical uncoupling effects of two engaged high-shearing rotor force chemical effect and the chemical depolymerization effect of a regeneration agent; the physical mechanical performance of the regenerated rubber is obviously improved; the automatic environment-friendly safe efficient and high-quality regeneration of waste rubber is realized.

Description

Technical field: [0001] The invention belongs to the technical field of waste rubber recycling and processing equipment, and in particular relates to waste rubber low-temperature regeneration equipment, which can desulfurize and regenerate waste rubber under low temperature conditions based on high-shear tooth-shaped components and a gear pump. Background technique: [0002] Since rubber is an important strategic material, countries all over the world have strict control measures for rubber. China is a big country that uses rubber, but its rubber resources are relatively scarce. About 70% of the annual rubber consumption is imported. In order to solve the shortage of rubber resources, we are advocating, encouraging and supporting the recycling of waste rubber and the call for reclaimed rubber. Under the current situation, a large number of rubber product factories use recycled rubber as a substitute for natural rubber to improve the utilization of rubber resources. The reus...

Problems solved by technology

[0003] Waste rubber recovery and reuse process equipment mainly includes steam type (heat transfer oil type, infrared direct heating type) desulfurization tank, reclaimed rubber kneader, reclaimed rubber internal mixer, and high-temperature continuous desulfurization machine at atmospheric pressure with a relatively high application rate. During the entire regeneration process of the process equipment, the rubber material needs to be kept in a relatively high temperature environment. Harmful gases will be emitted during the processing process, causing pollution to the atmospheric environment, and high temperature and high pressure conditions must be maintained during the processing process. Certain potential safety hazards, in the face of increasingly severe environmental pollution and the risk of safety accidents, it is imminent to develop efficient and pollution-free reclaimed rubber production equipment and processes
