Equipment and method for preparing high-performance modified pitch particles through abandoned clothing fibers
The invention provides equipment and method for preparing high-performance modified pitch particles through abandoned clothing fibers. The equipment comprises a mixing cavity, a high-pressure jet flow mechanism or a high-pressure extrusion mechanism, a cutting mechanism and short fiber blowing mechanism. The method includes the steps that firstly, abandoned clothing is crushed into short fibers ranging from 3 mm to 6 mm in size, and pitch is softened into a melt shape; then, the short fibers are blown upwards from the bottom of the mixing cavity, melt line-shaped pitch is sprayed downwards from the upper portion of the mixing cavity, the line-shaped pitch is cut into short pitch particles through the cutting mechanism and is in full contact with the sticky surfaces of the ascending short fibers in the descending process, the short fibers are arranged on the surfaces of the pitch particles in a wrapping mode, and the modified pitch particles can be obtained after vibration with a vibrating screen and cooling. By means of the equipment and the method, the problem that the short fibers and the pitch are not evenly mixed due to high adhesion of the pitch particles can be effectively avoided, the produced pitch particles are convenient and fact to transport, the laying process is simple, and the problem that the short fibers are distributed unevenly due to secondary melting of pitch laid in a road can be effectively avoided.
