Problems solved by technology

Due to the high viscosity of asphalt, it is not only difficult to mix the clothes scraps evenly with the molten asphalt, but also the clothes scraps will agglomerate in the asphalt, which will reduce the quality of the modified asphalt

Embodiment 1

[0027] Such as Figure 1-3 As shown, a device for preparing modified asphalt granules by using waste clothes includes a mixing chamber 1, a high-pressure jet mechanism or a high-pressure extrusion mechanism 2 is arranged above the mixing chamber 1, and the jet port or high-pressure jet of the high-pressure jet mechanism The extrusion port 21 of the extrusion mechanism communicates with the mixing chamber, and the jet port or the extrusion port is provided with a cutting mechanism 3 for transversely cutting the linear asphalt ejected from the jet port or extruded from the extrusion port. Both sides of the bottom are provided with blowing mechanism 4, and described blowing mechanism is used for blowing short fiber upwards from the bottom of the mixing chamber.

[0028] Preferably, a vibrating screen 5 is provided at the bottom of the mixing chamber, and the asphalt granules wrapped in short fibers fall into the vibrating sieve, so that the short fibers are further uniformly and ...

Embodiment 2

[0034] A method for preparing modified asphalt granules from waste clothes, comprising the steps of:

[0035] S1. Remove the buttons, zippers and other accessories from the waste cotton or chemical fiber clothing, and then pulverize them into short fibers of 3-6mm through a pulverizer;

[0036] S2, softening the asphalt into a molten state through high temperature;

[0037] S3. In a mixing chamber, short fibers are blown upward from the bottom of the mixing chamber, and molten linear asphalt is sprayed downward from the upper part of the mixing chamber. The linear asphalt is cut into short asphalt particles by a cutting mechanism, and the rising short fibers are combined with short asphalt particles. The outer surface is in contact with the surface of the asphalt particles under the action of viscosity, and the asphalt particles wrapped with short fibers fall to the bottom of the mixing chamber. A vibrating screen is installed at the bottom of the mixing chamber. Under the vib...

Abstract

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.

Description

technical field [0001] The invention relates to the field of road engineering materials, in particular to a device and a method for preparing high-performance modified asphalt granules from waste clothing fibers. Background technique [0002] Asphalt pavement is various types of pavement formed by paving and rolling asphalt concrete. Asphalt concrete is a mixture formed by fully mixing asphalt materials with a certain viscosity and appropriate dosage and mineral aggregates of a certain grade. Asphalt concrete, as an asphalt pavement material, has to bear the repeated action of running vehicle loads and the long-term impact of environmental factors during its use. Therefore, while asphalt concrete has a certain bearing capacity, it must also have good durability against natural factors. That is to say, it should be able to show sufficient stability in high temperature environment, crack resistance in low temperature condition, good water stability, long-lasting anti-aging a...
