Description

Technical Field

[0001] This utility model relates to the technical field of asphalt emulsification devices, specifically to emulsified asphalt processing equipment. Background Technology

[0002] In the field of road construction and maintenance, asphalt emulsification is a key technology. It involves melting asphalt and then mixing it with an aqueous emulsifier solution through mechanical action to form an oil-in-water emulsion. This type of emulsified asphalt can be used at room temperature, is easy to apply, and can reduce energy consumption and environmental pollution. It is widely used in road paving, sealing treatment, and other applications.

[0003] Traditional emulsified asphalt processing equipment meets production needs to a certain extent, typically possessing basic functions such as asphalt storage, emulsifier storage, and mixing. However, such equipment has significant drawbacks: Firstly, during the mixing process, air is easily incorporated into the emulsified asphalt, resulting in an excessively high air bubble content. This severely affects the stability and adhesion of the emulsified asphalt, reducing the quality and durability of the paved road. Secondly, during storage, impurities in the asphalt and emulsifier gradually accumulate at the bottom of the storage tank. However, traditional equipment generally lacks an effective slag removal function at the bottom, inevitably allowing these impurities to enter the emulsification process, greatly affecting the emulsification quality and consequently negatively impacting the overall quality of the road project.

[0005] This invention provides an emulsified asphalt processing equipment that solves the problems of high bubble content caused by air mixing during the mixing of emulsified asphalt in traditional equipment, as well as the problems of impurity deposition and lack of bottom slag discharge function affecting emulsification quality during asphalt and emulsifier storage.
