Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The first embodiment of the present invention discloses a rubber desulfurization method and device. Before desulfurization, the rubber is pulverized; in the pulverization process, the rubber material is put into an internal mixer for pulverization, and the pulverized rubber particles have a size of Between 1mm and 30mm, the temperature required for crushing is controlled at 160-170°C, and the pressure is set at 18-25MPa; the microwave desulfurization process is divided into the first stage of microwave desulfurization and the second stage of microwave desulfurization; the first stage is carried out first Microwave desulfurization, the microwave desulfurization steps are: firstly carry o...

Abstract

The invention provides a rubber desulphurization method and apparatus. The microwave desulphurization method comprises first-stage microwave desulphurization and second-stage microwave desulphurization; the first-stage microwave desulphurization comprises the steps of primary microwave heating, cooling and mechanical shearing; and the second-stage microwave desulphurization is carried out then, and comprises the steps of secondary microwave heating, cooling, and mechanical shearing. The desulphurization apparatus comprises a feeding tube, a feeding mechanism, a desulphurization mechanism, a discharging tube and a discharging mechanism; one side of the desulphurization mechanism is connected with the feeding tube, and the other side of the desulphurization mechanism is connected with the discharging tube; the feeding mechanism is arranged in the feeding tube; the discharging mechanism is arranged in the discharging tube; and the feeding tube is same to the discharging tube in profile and dimension. The method and the apparatus allow rubber to be thoroughly desulphurized, and the desulphurization apparatus has the advantages of simplicity and low production cost.

Description

technical field [0001] The invention relates to the technical field of rubber desulfurization, in particular to a rubber desulfurization method and device. Background technique [0002] China is a country that is relatively short of raw rubber resources. About 50% of China's annual consumption of reclaimed rubber needs to be imported. Finding the source of rubber raw materials and their substitute materials is an unremitting task for China. Therefore, carefully and properly disposing of waste rubber has extremely far-reaching positive and practical significance for making full use of renewable resources, getting rid of the lack of natural resources, reducing environmental pollution, and improving the living environment of the people. Reclaimed rubber has always been an important raw material for the world's rubber industry. On the one hand, it can replace rubber and alleviate the serious shortage of natural rubber; on the other hand, it enables waste rubber to be recycled an...
