Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides an embodiment: Please refer to Figures 1-5 An asphalt distillation apparatus includes a base 1 and an asphalt distillation apparatus body. The asphalt distillation apparatus body includes a distillation section 15 and an exhaust section 3. Several distillation sections 15 are circumferentially distributed on the base 1. A rotating plate 2 is movably connected to the top of the base 1. The exhaust section 3 is connected to the rotating plate 2. A first driving structure 11 is provided on one side of the top of the base 1. The rotating plate 2 is driven to rotate by the first driving structure 11. Under the action of the first driving structure 11, the rotating plate 2 can rotate. When the rotating plate 2 rotates, it can drive the exhaust section 3 to rotate, so that the exhaust section 3 can form an asphalt distillation apparatus with the distillation sections 15 at different positions. This allows the apparatus to quickly replace the distillation sections 15 during use, preheating the next distillation section 15 to be used during the asphalt distillation process. Asphalt feeding can be performed during the discharge of asphalt residue, improving the utilization rate of the apparatus. A slag discharge valve 12 is provided in the middle of the bottom of the distillation section 15, which can be used to discharge the residue inside the distillation section 15.

[0022] In Embodiment 1, the first drive structure 11 is a servo motor. The output shaft end of the first drive structure 11 is connected to a first gear through a reducer and a coupling. The outer side wall of the rotating plate 2 is connected to a second gear. The first gear and the second gear are in a meshing state. When the first drive structure 11 is working, it can drive the first gear connected to it to rotate. The first gear drives the rotating plate 2 to rotate through the second gear meshing with it.

[0023] A cleaning structure is provided on the top of the rotating plate 2. The cleaning structure includes a lifting structure 9, which is connected to the rotating plate 2 via a support frame 21. The end of the output shaft of the lifting structure 9 is connected to a cleaning plate 10, which is movably connected to the rotating plate 2. The cleaning plate 10 is adapted to the inner cavity of the distillation section 15. When the exhaust section 3 is aligned with the distillation section 15, the cleaning plate 10 is aligned with another distillation section 15. Through the setting of the cleaning structure, when the distillation section 15 aligned with the exhaust section 3 changes, the cleaning plate 10 is aligned with the distillation section 15 containing asphalt residue. When the lifting structure 9 is working, it can drive the cleaning plate 10 connected to it to move. The cleaning plate 10 can move into the inner cavity of the distillation section 15. When the cleaning plate 10 moves down in the distillation section 15, it can squeeze the asphalt residue, improving the asphalt residue discharge efficiency. At the same time, the cleaning plate 10 can scrape off the asphalt residue adhering to the inner wall of the distillation section 15, which facilitates the cleaning of the distillation section 15.

[0024] In Example 2, the lifting structure 9 is a hydraulic telescopic rod.

[0025] Preferably, there are two distillation sections 15. When the distillation section 15 needs to be cleaned, the user can remove the cleaning structure.

[0026] The exhaust section 3 is equipped with an exhaust port 14 and an electric feeding valve 13. The top of the electric feeding valve 13 is connected to an asphalt storage tank 20. The top of the asphalt storage tank 20 is equipped with an electric feed valve 5. The asphalt to be distilled can enter the asphalt storage tank 20 through the electric feed valve 5. The asphalt in the asphalt storage tank 20 can enter the asphalt distillation device through the electric feeding valve 13 to realize feeding.

[0027] Two electric exhaust valves 22 are provided at the outlet end of exhaust port 14. An insulation sleeve 4 is provided on the outer wall of the asphalt storage tank 20, forming a cavity between the insulation sleeve 4 and the asphalt storage tank 20. Heat exchange tubes 16 are installed within the cavity. The inlet end of each heat exchange tube 16 is connected to the outlet end of one of the electric exhaust valves 22. The number of heat exchange tubes 16 is the same as the number of exhaust ports 14. The heat exchange tubes 16 are S-shaped. Figure 4As shown, the bottom of the heat exchange tube 16 is connected to a liquid collection tank 19 via a connecting pipe 18, and an electric drain valve 17 is installed at the bottom of the liquid collection tank 19. Due to the arrangement of the heat exchange tube 16, when the electric exhaust valve 22 connected to the heat exchange tube 16 is open, the gas generated during the asphalt distillation process can enter the heat exchange tube 16 through the exhaust port 14 and the electric exhaust valve 22. During the movement of the gas within the heat exchange tube 16, it can exchange heat with the asphalt in the asphalt storage tank 20, thus preheating the asphalt. When the electric exhaust valve 22 connected to the heat exchange tube 16 is closed, the gas generated during the asphalt distillation process is discharged through another electric exhaust valve 22. This allows the preheating time of the asphalt to be controlled according to requirements during use, improving the adaptability of this application. Furthermore, under the influence of gravity, the gas liquefaction products during the heat exchange process can enter the liquid collection tank 19 through the connecting pipe 18. The controller of this application can periodically control the electric drain valve 17 to open and discharge the liquid collected in the liquid collection tank 19, which facilitates the processing of liquefaction products.

[0028] A temperature sensor 7 is installed on the asphalt storage tank 20. The temperature sensor 7 can monitor the temperature of the asphalt in real time. When the asphalt temperature meets the feeding temperature, the distillation gas is stopped from being introduced into the heat exchange tube 16 to avoid the asphalt temperature being too high and affecting the distillation.

[0029] A stirring rod 6 is installed in the middle of the inner cavity of the asphalt storage tank 20, and a second driving structure 8 is installed on the top of the asphalt storage tank 20. The stirring rod 6 is driven to rotate by the second driving structure 8. When the second driving structure 8 drives the stirring rod 6 to rotate, the stirring rod 6 can stir the asphalt and improve the uniformity of the asphalt heating.

[0030] In Example 3, the second drive structure 8 is connected to the top of the asphalt storage tank 20. The second drive structure 8 is a servo motor. The output shaft of the second drive structure 8 is connected to a third gear through a reducer and a coupling. The top of the stirring rod 6 is connected to a fourth gear. The third gear and the fourth gear are in a meshing state. When the second drive structure 8 is working, it can drive the third gear connected to it to rotate. The third gear can drive the stirring rod 6 to rotate through the fourth gear meshing with it.

[0031] In addition, a sealing gasket is provided between the rotating plate 2 and the base 1 to ensure the airtightness between the exhaust section 3 and the distillation section 15, facilitating the distillation of asphalt. The material of the sealing gasket can be set according to requirements and is not limited here.

[0032] The asphalt distillation unit formed by exhaust section 3 and distillation section 15 can be flexibly configured with the required structure according to actual process requirements, such as asphalt heating device, temperature sensor, etc., without specific limitations.

[0033] All electrical components involved in this application are existing technologies. Those skilled in the art can select appropriate models of electrical components according to their needs. No restrictions or elaborations are made here. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies are connected by wires. According to the actual situation, appropriate controllers are selected to meet control requirements. For specific connections and control sequences, please refer to the description below. The electrical connections between each electrical component are completed in the order of their operation. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0034] In summary: When the asphalt distillation device is in use, the first drive structure 11 drives the rotating plate 2 to rotate, so that the exhaust section 3 is aligned with the distillation section 15. During feeding, the asphalt to be distilled can enter the asphalt storage tank 20 through the electric feed valve 5. The asphalt in the asphalt storage tank 20 can enter the asphalt distillation device through the electric feed valve 13, thus realizing feeding. During the asphalt distillation process, the asphalt to be distilled in the next stage is injected into the asphalt storage tank 20. The gas generated during the asphalt distillation process is directed to the subsequent processing stage through the exhaust port, an electric exhaust valve 22, and the heat exchange tube 16. As the gas moves within the heat exchange tube 16, it can exchange heat with the asphalt in the asphalt storage tank 20, thus preheating the asphalt. During the asphalt preheating process, the second drive structure 8 drives the stirring rod 6 to rotate, and the stirring rod 6 stirs the preheated asphalt to improve the uniformity of asphalt heating. The temperature sensor 7 detects the asphalt preheating temperature in real time. The controller of this application controls the asphalt heating time according to the asphalt detection temperature and the preset asphalt feeding temperature. When the asphalt preheating temperature reaches the preset asphalt feeding temperature, another electric exhaust valve 22 is in the open state, and the electric exhaust valve 22 connected to the heat exchange tube 16 is in the closed state. The gas generated during the asphalt distillation process is directed to the subsequent processing stage through the exhaust port and the other electric exhaust valve 22.

[0035] During the asphalt distillation process, the controller of this application controls the heating device installed in the distillation section 15 to preheat another distillation section 15 to be used. After the asphalt distillation is completed, the first drive structure 11 drives the rotating plate 2 to rotate, so that the exhaust section 3 is aligned with the preheated distillation section 15. At this time, the cleaning plate 10 moves above the distillation section 15 containing asphalt residue, and the preheated asphalt can be discharged into the preheated distillation section 15. During the feeding process, the slag discharge valve 12 at the bottom of the distillation section 15 containing asphalt residue is in the open state, and the lifting structure 9 drives the cleaning plate 10 to move. The cleaning plate 10 can squeeze the asphalt residue to improve the asphalt residue discharge efficiency.
