Problems solved by technology

This invention controls the asphalt flow through the output of the asphalt pump, without considering the influence of the structural size of the asphalt pipeline on the flow characteristics of hot asphalt and foamed water
In fact, if the design parameters of the pipeline change, the flow characteristics of the fluid in the pipeline will also change, which will affect the accuracy of the system to control the bitumen flow

Abstract

The invention relates to modular designed asphalt foaming equipment and an automatic control system thereof. The asphalt foaming equipment is composed of an asphalt supply system, a foaming water supply system, a humidification water supply system, an air supply system and a foamed asphalt spraying rod, wherein the asphalt supply system, the foaming water supply system, the humidification water supply system and the air supply system are independent modules separately. The automatic control system of the asphalt foaming equipment can automatically calculate the amount of asphalt, foaming waterand compressed air which are required for the preparation of foamed asphalt through a piping graphic design unit preinstalled in a computer or a touch screen and according to the input data such as the type of road building construction equipment, and can automatically calculate main design parameters of an asphalt pipeline, a foaming water pipeline and an air pipeline. The modular designed asphalt foaming equipment is convenient to disassemble and assemble and can be combined with various road building construction equipment; and the automatic control system can accurately control the flow rate of the asphalt and the amount of the foaming water, the foaming quality of the asphalt is ensured, and mixing is realized while foaming is carried out.

Description

technical field [0001] The invention relates to a modular design of asphalt foaming equipment and its automatic control system. Background technique [0002] my country has entered a large-scale road repair period, and a large amount of waste asphalt pavement materials are produced every year. Foamed asphalt regeneration technology can effectively recycle these materials with its unique advantages of "energy saving, environmental protection, and remarkable economy". [0003] Asphalt foaming is to pass air, atomized water, and asphalt heated to a certain temperature into a specific cavity at the same time, and a series of complex physical changes will occur, resulting in a rapid increase in the volume of the original asphalt, forming a sponge-like Structural foam bitumen. The viscosity of foamed asphalt is significantly lower than that of ordinary asphalt, and it has good adhesion performance after mixing with the mixture, which can realize road construction technologies suc...
