A Granular Trans Isoprene Rubber Aftertreatment System

Abstract

The invention relates to the technical field of isoprene rubber devices, in particular to a granular trans isoprene rubber post-processing system, which includes an inner cylinder, a screw extruding rod is arranged in the middle of the inner cylinder, and a screen cylinder is arranged outside the inner cylinder , the inner wall of the screen cylinder is uniformly provided with spiral blades, and one end of the screen cylinder is fixedly connected to the machine head, and the machine head is connected to one end of the inner cylinder in rotation, and an outer cylinder is provided on the outside of the screen cylinder, and the outer cylinder and the machine head rotate Connection; one end of the machine head is provided with a discharge ring, and the side wall of the discharge ring is evenly distributed with small holes, the small holes communicate with the inner cavity of the machine head, and the outer rotating sleeve of the discharge ring is provided with Knife ring, the invention sets a machine head that can be rotated independently at the front end of the inner cylinder, which can improve friction heat generation and promote material flash evaporation, and the independently rotating machine head can drive the screen cylinder to rotate at the same time, and the screen cylinder rotates during the rotation process Evaporate the water on the surface of the rubber particles to achieve pre-drying, share the burden of expansion extrusion drying, and improve the drying effect.

Description

technical field [0001] The invention relates to the technical field of isoprene rubber devices, in particular to a granular trans isoprene rubber aftertreatment system. Background technique [0002] Isoprene rubber is a high-performance rubber used in tire production. It is widely used in the tire manufacturing industry due to its stable chemical properties. It has good elasticity, cold resistance (glass transition temperature -68°C) and high tensile strength. Under the conditions of oxidation resistance and multiple deformation, the resistance to notch tearing is higher than that of natural rubber, but the processing performance such as mixing and calendering is slightly worse than that of natural rubber. With the development of the isoprene rubber industry, the demand for isoprene in the future society will be even greater. [0003] Chinese utility model patent (CN206812270U) discloses a granular trans isoprene rubber post-treatment system, the utility model relates to a...

Problems solved by technology

[0005] (1) After the rubber particles come out of the water, they not only contain moisture inside, but also on the surface. The rubber particles are directly extruded, expanded and dried by the expansion dryer. It is necessary to remove the internal moisture and surface moisture of the rubber particles at the same time, resulting in the burden of the expansion dryer. Very large, low drying efficiency

[0006] (2) The extrusion surface of the rubber is longitudinal, and the rubber particles are also arranged vertically when they are discharged, and the gas after flashing is also discharged vertically upwards, which causes the rubber particles located in the lower part of the longitudinal arrangement to evaporate when the rubber particles are discharged The gas will collide with the upper rubber particles, resulting in poor discharge of evaporated gas, reducing the evaporation efficiency and effect
