[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes. Example

[0024] See also Figure 1 to Figure 5 In this embodiment, a device for utilizing asphalt waste heat in a tar distillation section is provided, including a heat exchange box 1, a serpentine tube 2 is installed in the heat exchange box 1, one end of the serpentine tube 2 extends out of the top wall of the heat exchange box 1, and the other end passes through the bottom of the heat exchange box 1, so that high-temperature asphalt is added from the top inlet of the serpentine tube 2, and is discharged from the top outlet after being transported by the tube body. In this process, the liquid added in the heat exchange box 1 can absorb the heat emitted by the asphalt and heat it, thereby utilizing the waste heat of the asphalt. Correspondingly, a liquid inlet pipe 3 is installed on the top of the heat exchange box 1, and a liquid outlet pipe 4 is arranged at the bottom thereof. The arrangement of the liquid inlet pipe 3 and the liquid outlet pipe 4 allows the liquid to be heated to be added and the heated liquid to be discharged;

[0025] For a conventional heat exchange box 1, it can generally only heat one liquid at a time, and its adaptability is not good enough. However, the present application is different. It is provided with storage mechanisms 5 on both the front and rear sides of the serpentine tube 2 in the heat exchange box 1. The storage mechanism 5 can rotate in the heat exchange box 1, thereby stirring and mixing the liquid in the heat exchange box 1, increasing the heat exchange effect, and making the liquid heating more uniform. At the same time, new liquid can be injected into it, and when it is stirred, it can also absorb heat to heat the new liquid inside it, thereby better utilizing the waste heat of the asphalt and achieving the effect of simultaneous heating.

[0026] The storage mechanism 5 includes a tank body 51, the interior of which is a hollow structure and is made of copper, so that it has a good heat absorption effect and can absorb the heat in the heat exchange box 1 well, thereby heating the liquid inside it. Rotating shafts 52 are arranged on the left and right sides of the tank body 51, and the two rotating shafts 52 extend out of the side wall of the heat exchange box 1 and are rotatably connected thereto. The rotation of the tank body 51 can be realized by the arrangement of the rotating shafts 52. At the same time, the interior of the rotating shaft 52 is a hollow structure, and it is connected to the interior of the tank body 51, so as to realize the addition and discharge of external liquid. In addition, a valve 53 is also installed at the end of the rotating shaft 52, which plays the role of a switch, which is opened when adding or discharging liquid, and conversely, it is closed so that the liquid can be retained in the tank body 51.

[0027] A plurality of stirring blocks 55 are arranged on the outer wall of the tank body 51. Each stirring block 55 is evenly spaced and circumferentially distributed on the tank body 51. When the tank body 51 rotates, the stirring blocks 55 rotate accordingly, which can increase the stirring effect. A driven tooth 54 is also installed on one of the rotating shafts 52. The driven tooth 54 engages with the power structure 6. The power structure 6 can drive the driven tooth 54 to rotate. The driven tooth 54 drives the rotating shaft 52 to rotate, thereby rotating the tank body 51 and the stirring blocks 55 to achieve the purpose of stirring the liquid.

[0028] The power structure 6 includes a motor 61, which is arranged on a mounting plate 62, and the mounting plate 62 is fixedly mounted on the outer wall of the heat exchange box 1. In addition, a main gear 63 meshing with the driven gear 54 is also installed on the motor shaft of the motor 61. When the motor 61 is started, it drives the main gear 63 to rotate, and the main gear 63 drives the driven gear 54 to rotate, and then the tank body 51 is driven to rotate to achieve stirring.

[0029] In the utility model, the power structure 6 drives the storage mechanism 5 to rotate, which can accelerate the heat exchange effect between the liquid in the heat exchange box 1 and the asphalt in the serpentine tube 2. In addition, liquid materials can be added to the storage mechanism 5, so that the heat exchange box 1 can heat a variety of different liquid materials at the same time, thereby improving adaptability and scope of use, and has good practicality.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
