Study On The Of Asphalt Rubber Equipment

Rubber asphalt has large viscosity, strong adhesion, good performance at a lowtemperature, and low temperature sensitivity. In recent years, with the development of rubberasphalt technology, rubber asphalt has been widely used in road construction. With thegrowing use amount of rubber asphalt, its production equipment has large production capacity,convenient use, high efficiency and so on.In order to solve the problem of low efficiency of heating asphalt, with the study ofvarious heating methods and analyzing their respective advantages and disadvantages,determine the method of using heat conduction oil indirectly to heat asphalt in practicalengineering. By studying mechanism of heating asphalt, it provides a basis to determine theheat transfer. spiral plate heat exchanger has high thermal efficiency, small size In practicalengineering.Through studying the solid-liquid two-phase mixing problems, and found a problem oflow mixing efficiency in the mixing tank, which is caused by flow pattern in the flow fieldand flow pattern is inappropriate. The axial flow and radial flow plays a main role for mixing,but tangential flow should avoid being present in the flow field. By designing the drumstructure, putting forward the evaluation criterion of the mixing effect of rubber powdermixing uniformity, using fluent fluid software to simulate the mixing tank, and analysis themain factors influencing the mixing effect such as agitator diameter, rotating speed of stirrer,stirrer position and damper, and use the criterion of the simulation results under differentconditions to evaluate factors, then obtain reasonable values of these factors. Through thestudy of the simulation of the improved agitation tank, find its mixing effect is good, andrealize uniform suspension results of rubber powder in the matrix asphalt.
