Waste rubber powder special charging device and charging method capable of computation weighing

Abstract

The invention relates to a waste rubber powder special charging device and a charging method capable of computation weighing, and discloses the waste rubber powder special charging device capable of computation weighing. The waste rubber powder special charging device capable of computation weighing comprises a material charging device, a weighing mechanism, a blowing and conveying system and a control module. The invention further discloses the waste rubber powder charging method capable of computation weighing. According to the waste rubber powder charging device and method capable of computation weighing provided by the invention, an intelligent waste rubber powder charging mode is adopted, so that the working environment of workers is improved; the labor intensity of the workers is lowered; the quality of asphalt mixed materials is improved; the device is interconnected with and communicates with an asphalt mixing station control system, so that manual operation error is reduced; and according to the project of the invention, based on the principles of precise and rapid material charging and manual error reducing, the intelligent waste rubber powder weighing charging method is provided, so that the charging and adding of waste rubber powder are more reasonable and scientific; and the technical level of mixing construction of rubber-asphalt mixed materials of asphalt pavements is improved.

Description

technical field [0001] The invention belongs to the field of conveying devices, in particular to a measuring and weighing type waste rubber powder special feeding device and a feeding method. Background technique [0002] Process waste tires into waste rubber powder of more than 20 meshes, add a certain proportion of waste rubber powder to base asphalt, and make rubber asphalt after fully reacting under high temperature conditions. Since rubber is a kind of high molecular compound, in addition to being elastic, it also has high self-adhesiveness and inter-adhesiveness. When rubber powder and asphalt are melted together, the viscosity of asphalt increases significantly, which is beneficial to improve the cementation of asphalt mixture. At the same time, asphalt has the characteristics of rubber elasticity and flexibility, so as to improve the high temperature stability and low temperature crack resistance of rubber asphalt concrete. Practice has proved that the application o...

Problems solved by technology

[0003] The storage stability of rubber asphalt has become a technical problem in the application. Since the density of rubber asphalt is higher than that of base asphalt, the rubber powder gradually sinks and causes segregation during the use and storage of rubber asphalt, making it difficult to achieve satisfactory road performance.
