Description

Technical Field

[0001] This utility model relates to the field of asphalt heating technology, specifically to an emulsified asphalt heating device for road paving. Background Technology

[0002] With the accelerated pace of transportation infrastructure construction and the continuous improvement of engineering construction standards, higher requirements are being placed on road paving materials. Emulsified asphalt, as a high-quality paving material, is widely used due to its unique properties. Emulsified asphalt is a material made by emulsifying and mixing asphalt and water through physical or chemical methods. It can be applied at room temperature and possesses good adhesion and workability.

[0003] Heating equipment plays a crucial role in the production of emulsified asphalt. However, current emulsified asphalt heating equipment on the market has certain shortcomings. For example, some equipment uses an external thermal oil boiler for heating, which not only requires a dedicated boiler operator, increasing labor costs, but also has relatively high equipment costs. Another method uses open flame heating with combustion tubes, which, although simple in structure, has low thermal efficiency, thus increasing fuel costs. Therefore, we propose an emulsified asphalt heating device for road paving. Utility Model Content

The design of the push plate simplifies operation, allowing for flexible adjustment of position or application of force as needed. The first and second vertical support plates on both sides of the upper surface of the push plate further enhance the structural stability. These two vertical support plates provide excellent lateral support, preventing lateral displacement or deformation of the push plate under stress, thus ensuring the stability and durability of the entire structure. A heating tank is mounted on the first and second vertical support plates via a rotating connecting rod. An electric heating plate is installed on the upper surface of the push plate, located directly below the heating tank. The heating tank can be flexibly adjusted in angle or position to adapt to different heating needs. The installation of the rotating linkage not only enhances the stability of the heating tank but also makes its operation easier. The electric heating plate installed on the upper surface of the push plate provides a stable heat source for the heating tank, ensuring uniform heating and efficient heating of the emulsified asphalt during the heating process.
