Description

Technical Field

[0001] The utility model belongs to the technical field of heating and mixing asphalt and a regenerating agent, and particularly relates to a heating and mixing device for asphalt and a regenerating agent. Background Art

[0002] Asphalt is a complex mixture with high viscosity. It needs to be heated to become liquid, and the performance of asphalt is greatly affected by temperature. When regenerating aged asphalt, it is necessary to mix the aged asphalt with a regeneration agent.

[0003] The most commonly used mixing method at present is to add the regeneration agent directly into the heated aged asphalt, which results in uneven diffusion and poor regeneration effect, thus wasting a lot of recycling resources and labor costs, and affecting the environment. Therefore, we proposed a heating mixing device for asphalt and regeneration agent. Utility Model Content

[0004] The purpose of the utility model is to provide a heating and mixing device for asphalt and a regeneration agent, which is specifically arranged in a spiral shape through the stirring blades inside the mixing drum so that the slide is arranged downward, and then the asphalt flows out through the slide in a concentrated manner for collection and use, thereby avoiding the danger of splashing caused by spilling and also avoiding waste, thus saving materials and solving the problem that the existing mixing method that is currently mostly used is to add the regeneration agent directly into the heated aged asphalt, which causes uneven diffusion and poor regeneration effect, thereby resulting in a large waste of recycling resources and labor costs, and affecting the environment.
