Description

Technical Field

[0001] The utility model relates to the technical field of asphalt processing, in particular to an emulsified asphalt mixer. Background Technique

[0002] Emulsified asphalt is a viscous asphalt that is dispersed in water containing an emulsifier-stabilizer in the form of micro-droplets through heat fusion and mechanical action, forming an oil-in-water (O / W) type asphalt emulsion. Emulsified asphalt is a road construction material that liquefies the road asphalt usually used at high temperatures through mechanical stirring and chemical stabilization (emulsification) and diffuses it into water, resulting in a very low viscosity and good fluidity at normal temperature. It can be used at normal temperature or with cold and wet stone materials.

[0003] There are some deficiencies in the existing emulsified asphalt mixers during use. For example, during the stirring process, asphalt is prone to adhering to the side walls, which is likely to cause waste, and during the processing process, it is prone to uneven heating. Therefore, we propose a new type of emulsified asphalt mixer. Content of the Utility Model
