Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to a preparation device for anti-caking circulating washing of asphalt. Background Technique

[0002] In highway and road construction, a large amount of road asphalt mixture is needed. In the prior art, when preparing the asphalt mixture, since the modifier and asphalt need to be mixed and compatible at a certain high temperature, the asphalt is usually heated first, and the asphalt and the modifier are injected into the stirring tank to quickly and evenly mix and be compatible. However, since the asphalt is in a molten state and has a certain viscosity during the stirring process, the asphalt is likely to adhere to the inner wall of the tank and form slag, which affects the preparation effect of the asphalt by the asphalt stirring tank and is difficult to clean. Therefore, a preparation device for anti-caking circulating washing of asphalt is proposed. Content of the Utility Model
