Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to a stirring device for producing water-emulsion asphalt road and bridge coatings. Background Technique

[0002] Asphalt is a brown or black-brown organic cementitious material and an indispensable material in civil engineering construction. It has wide applications in projects such as buildings, roads, and bridges. Asphalt waterproof coatings are solvent-based or water-emulsion waterproof coatings formulated with asphalt as the base material. Solvent-based asphalt waterproof coatings refer to those prepared by directly dissolving unmodified petroleum asphalt in solvents such as gasoline, also known as primer. Water-emulsion asphalt waterproof coatings refer to coatings formed by dispersing petroleum asphalt in water under the action of chemical emulsifiers or mineral emulsifiers to form a stable water dispersion. In the asphalt production process, a stirring device is needed to assist in uniformly mixing various raw materials.

[0003] The existing stirring device has a fixed structure itself and can only be adapted to specific models of mixing tanks. Moreover, during the stirring operation, a large amount of asphalt raw materials adhere to the surface of the existing stirring device. Directly taking out the stirring device from the asphalt not only causes waste of some asphalt, but the residual asphalt coagulating on the surface of the stirring device will seriously affect the normal use of the stirring device and the purity of the asphalt during the next stirring operation.
