[0002] An immersion tank is a device used to immerse an object in a liquid, typically to improve its durability, corrosion resistance, or other specific physical and chemical properties.

[0003] After searching, the announcement number is CN219079405U, and the name is a low-pressure vacuum impregnation tank for asphalt, including an impregnation tank body. Through research and analysis, it is found that although it has advantages such as improved working stability and improved internal impregnation efficiency during use, it still has the following disadvantages to a certain extent.

[0004] For example, it does not have a heat preservation function. During the use of the above-mentioned impregnation tank, the surface of the tank body does not have a heat preservation structure, which causes the heat inside the tank to be lost quickly, affecting the energy utilization rate, greatly increasing energy consumption, not energy-saving and environmentally friendly, and does not have a waste heat utilization function. When the lid is opened, the high-temperature asphalt fume cannot be collected and the waste heat cannot be utilized, causing the asphalt fume to float everywhere, which not only wastes resources but also affects the surrounding environment. In order to solve the above technical problems, we have designed a high-efficiency, energy-saving and multifunctional impregnation tank. Utility Model Content

The preheated asphalt is transported to the inner cavity of the inner shell 2 through the discharge pipe 27, the feed pipe 28 and the asphalt inlet and outlet pipe 9. When the inner shell 2 needs to be kept warm, high-temperature hot oil is input between the outer shell 3 and the inner shell 2 through the hot oil inlet pipe 11. The hot oil keeps the inner shell 2 warm to avoid heat loss and increase the subsequent impregnation effect.
