AI Technical Summary

Technical Problem

In the existing thin-layer asphalt mixing process, due to the influence of centrifugal force, solid particulate matter is prone to layering when stirring and mixing, resulting in low mixing uniformity, which affects the quality and performance of thin-layer cover.

Method used

A preparation device including a mixing assembly, a stirring assembly and a drive assembly is designed. The mixing component allows the inner mixing barrel to move circularly relative to the center of the outer mixing barrel by setting the outer mixing barrel, and combines the agitating part of the agitating component and the drive motor and drive part of the drive assembly to achieve uniform mixing of solid materials.

Benefits of technology

Through this device, the influence of centrifugal force on the mixture can be effectively reduced, the mixing uniformity of solid materials can be improved, and the quality and performance of the thin layer cover can be ensured.

Abstract

The invention relates to the technical field of solid material recycling, in particular to a preparation device and method for thin overlay asphalt, the preparation device comprises a mixing assembly, the mixing assembly comprises a fixedly arranged outer mixing barrel and an inner mixing barrel movably arranged on the inner side of the outer mixing barrel, and the inner mixing barrel can do circular motion relative to the center of the outer mixing barrel; the stirring assembly comprises a stirring part which is rotatably connected in the inner mixing barrel and is used for mixing and stirring materials in the inner mixing barrel, a second feeding hole and a second discharging hole are respectively formed in the top and the bottom of the inner mixing barrel, and the second discharging hole is formed in one side close to the center of the outer mixing barrel; and a driving assembly. Through mutual cooperation of the mixing assembly, the stirring assembly and the driving assembly, the phenomenon of single material concentration caused by centrifugal force during stirring and mixing of solid materials can be reduced, the final material mixture is more uniform, and the quality and performance of the final thin overlay are ensured.
