[0023] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0024] Example 1

[0025] like Figures 1 to 3 As shown, this embodiment designs a heat recovery asphalt storage tank, which includes two main parts: a heat medium tank 1 and an asphalt tank 2, wherein the asphalt tank 2 is located above the heat medium tank 1.

[0026] The asphalt tank 2 is used for storing asphalt slurry. The asphalt tank 2 is circular or elliptical, or it can be a vertical or horizontal polygonal structure. To achieve heat insulation of the asphalt tank 2, insulating materials such as foaming agents and sponges can be filled inside the tank wall.

[0027] An asphalt injection port 21 is provided on the tank wall of the asphalt tank 2; asphalt slurry can be injected into the asphalt tank 2 through the asphalt injection port 21, and asphalt slurry in the asphalt tank 2 can also be extracted outward. The asphalt injection port 21 can be located on the top wall or the side wall of the asphalt tank 2.

[0028] An openable cover plate 3 is provided on the asphalt injection port 21; the cover plate 3 can be rotatably connected to the edge of the asphalt injection port 21, so as to cover or close the asphalt injection port 21.

[0029] The heat medium box 1 is located below the asphalt tank 2. A heat exchange chamber is provided inside the heat medium box 1. The bottom wall of the asphalt tank 2 can be used as the chamber wall of the heat exchange chamber, so that the heat medium box 1 can exchange heat with the asphalt tank 2.

[0030] A support partition 4 is provided inside the heat exchange cavity, which divides the heat exchange cavity into an S-shaped channel. An inlet 12 and an outlet 11 are provided on the wall of the heat medium tank 1, which are located at the two ends of the S-shaped channel, respectively.

[0031] Temperature sensors 5 are installed at the outlet 11 and inlet 12 to measure the temperature of the heat medium as it enters and exits the heat exchange chamber. The outlet 11 and inlet 12 can be located on the side wall of the heat medium tank 1 on the same side.

[0032] The supporting partitions 4 are multiple, specifically, there are generally 3-5 supporting partitions 4. Adjacent supporting partitions 4 are staggered. When there are three supporting partitions 4, the supporting partitions 4 form... Figure 3 The structure shown.

[0033] The upper edge of the support partition 4 is connected to the upper cavity wall of the heat exchange chamber, and the lower edge of the support partition 4 is connected to the lower cavity wall of the heat exchange chamber, so as to realize the vertical support of the asphalt tank 2, thereby improving the support stability and reliability of the support partition 4.

[0034] The supporting partition 4 is a long strip plate. One end of the supporting partition 4 is connected to the side wall of the heat exchange cavity, and the other end of the supporting partition 4 is spaced apart from the side wall of the opposite side of the heat exchange cavity.

[0035] In this embodiment, when the heat recovery asphalt storage tank is in use, the heat medium enters the heat medium tank 1 through the inlet 12. As the heat medium flows along the S-shaped channel, it exchanges heat with the baffle and the bottom wall of the asphalt tank 2, thereby heating the asphalt in the asphalt tank 2 and ensuring that the asphalt remains in a liquid state during temporary storage. The source of the heat medium can be any other process in the asphalt processing, and the heat medium can be hot water, hot air, steam, etc.

[0036] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
