[0002] Asphalt is one of the core materials in road construction, and its storage quality directly affects the stability and service life of road construction. Maintaining a suitable temperature and ensuring its uniformity during asphalt storage are crucial to guaranteeing asphalt performance. Existing asphalt storage tanks often suffer from insufficient temperature control precision and easy heat loss. Furthermore, their poorly designed mixing mechanisms make it difficult to achieve comprehensive mixing of the asphalt within the tank, leading to asphalt stratification and affecting subsequent construction quality and asphalt performance. Utility Model Content
[0003] To address the problems of heat loss and incomplete mixing leading to asphalt stratification in existing technologies, a temperature-controlled, stratified mixing asphalt storage tank is proposed. This invention provides the following technical solution: A temperature-controlled, stratified, mixing asphalt storage tank includes a tank body and a drive motor. The tank body is horizontally positioned, with an inlet and an outlet at its front and rear ends, respectively. A heater is installed on the lower side of the tank body, comprising an electric heating plate and a heat insulation plate. The electric heating plate is positioned between the heat insulation plate and the tank body. A rotating shaft is rotatably connected to the tank body around a horizontal axis, and multiple stirring rods are mounted on the rotating shaft. The drive motor is connected to the rotating shaft via a transmission assembly. Each stirring rod includes a connecting rod, a mounting plate, and a stirring paddle. The two ends of the connecting rod are detachably connected to the rotating shaft and the mounting plate, respectively. The stirring paddle is fixedly connected to the mounting plate by bolts and is fan-shaped with its ends bent backward.
[0004] Preferably, the mounting plate has an acute angle between its surface and the front surface.

[0008] Preferably, the impeller includes an installation part and a stirring part, the front and rear end faces of the installation part are straight, the installation part is provided with mounting screw holes, and the stirring part is bent to the rear.
[0009] Preferably, a discharge valve is installed in the discharge port.
[0010] Preferably, the transmission assembly includes a driving pulley, a driven pulley, and a belt. The driving pulley is coaxially connected to a drive motor, the driven pulley is coaxially connected to a rotating shaft, and the belt is sleeved on the driving pulley and the driven pulley.
[0011] Preferably, the transmission assembly is provided with a transmission protective cover.
[0012] Preferably, the tank body is provided with an auxiliary port for feeding and observation, and a sealing baffle is installed on the auxiliary port.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0015] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.
[0016] like Figure 1-4 As shown, a temperature-controlled, layered, stirring asphalt storage tank includes a tank body 1 and a drive motor 5. The tank body 1 is horizontally positioned, with an inlet 11 and an outlet 13 at its front and rear ends, respectively. A heater 4 is installed on the lower side of the tank body 1. The heater 4 includes an electric heating plate 41 and a heat insulation plate 42, with the electric heating plate 41 positioned between the heat insulation plate 42 and the tank body 1. A rotating shaft 2 is rotatably connected to the tank body 1 around a horizontal axis. Multiple stirring rods 3 are mounted on the rotating shaft 2. The drive motor 5 is connected to the rotating shaft 2 via a transmission assembly 6, enabling omnidirectional stirring and fine mixing of the asphalt inside the tank. Precise temperature control ensures that asphalt maintains a uniform temperature and texture during storage, preventing uneven temperature or stratification during static storage from affecting subsequent use. The mixing rod 3 includes a connecting rod 31, a mounting plate 32, and a mixing paddle 33. The two ends of the connecting rod 31 are detachably connected to the rotating shaft 2 and the mounting plate 32, respectively. The mixing paddle 33 is fixedly connected to the mounting plate 32 by bolts. The mixing paddle 33 is fan-shaped with its ends bent backward. The fan-shaped structure expands the mixing contact area, and the bent ends can drive more asphalt flow. The detachable design facilitates the maintenance and replacement of the mixing unit 332 in the future.
[0017] Specifically, the tank body 1 includes an upper shell 101 and a lower shell 102. The lower shell 102 is fixed on the base, and the upper shell 101 and the lower shell 102 are threaded together.
[0018] Specifically, multiple sets of stirring rods 3 are evenly spaced along the axial direction on the stirring shaft, each set including four stirring rods 3 evenly spaced circumferentially, which can further improve the uniformity of stirring.
[0019] Specifically, the surface of the mounting plate 32 forms an acute angle with the front, causing the mixing paddle 33 to form an inclined mixing trajectory when rotating, which makes it easier to break the static layering state of the asphalt and improve the penetration of the mixing.
[0020] Specifically, the electric heating plate 41 is curved in an arc shape, and the surface of the electric heating plate 41 contacts the outer wall of the tank 1. The design that fits the shape of the tank 1 makes the heat transfer more direct and efficient, and avoids the occurrence of insufficient local heating.
[0021] Specifically, a partition is connected between the heat insulation plate 42 and the electric heating plate 41, and the heat insulation plate 42 and the electric heating plate 41 are spaced apart, forming a vacuum cavity between the heat insulation plate 42 and the electric heating plate 41. The vacuum structure can effectively block heat from escaping outward, improving heating efficiency while reducing energy consumption.
[0022] Specifically, the rounded corners of the ends and sides of the mixing paddle form rounded corners 333, which can reduce the shear damage to the asphalt during the mixing process, protect the original properties of the asphalt, and prevent damage to the components due to stress concentration at the corners.
[0023] Specifically, the mixing paddle includes an installation part 331 and a mixing part 332. The front and rear ends of the installation part 331 are set flat, and the installation part 331 is provided with a mounting screw hole 3311. The mixing part 332 is bent to the rear. The flat installation part 331 is convenient to be accurately connected and fixed with the mounting plate 32, while the bent mixing part 332 can enhance the pushing effect on the asphalt and promote the circulation of asphalt in the tank.
[0024] Specifically, a discharge valve 14 is installed in the discharge port 13, which can flexibly adjust the discharge rhythm according to the usage requirements. When closed, it can ensure the sealing of the tank 1 and prevent asphalt leakage or external pollution.
[0025] Specifically, the transmission assembly 6 includes a drive pulley 61, a driven pulley 62, and a belt 63. The drive pulley 61 is coaxially connected to the drive motor 5, the driven pulley 62 is coaxially connected to the rotating shaft 2, and the belt 63 is sleeved on the drive pulley 61 and the driven pulley 62. The belt drive operates smoothly and with low noise, and can stably transmit power to ensure the continuous normal operation of the stirring mechanism.
[0026] Specifically, a transmission protective cover 8 is provided on the outside of the transmission component 6, which can prevent dust and debris from entering the transmission component, reduce wear, and prevent personnel from accidentally touching the moving parts and causing safety accidents.
[0027] Specifically, the upper shell 101 of the tank body 1 is provided with an auxiliary port 12 for feeding and observation. Specifically, from front to back, it includes a first opening 121, a second opening 122 and a third opening 123. A sealing baffle 9 is installed on the auxiliary port 12. The feeding function meets the needs of adding additives, etc., and the observation function facilitates real-time monitoring of the tank's internal conditions. The sealing baffle 9 ensures the airtightness and heat preservation effect of the tank body 1.
[0028] Specifically, a cover plate 7 is slidably connected to the feed inlet 11. The sliding design makes it easy to open and close the cover plate 7. When closed, it can effectively block external impurities from entering the tank and reduce heat loss inside the tank.
[0029] Working process description: Asphalt is fed into tank 1 through inlet 11 and sealed by sliding cover 7. Heater 4 is activated, and electric heating plate 41 heats tank 1. Insulation plate 42 and vacuum chamber effectively prevent heat loss, ensuring uniform heating of the asphalt inside the tank. Drive motor 5 is activated, driving rotating shaft 2 through transmission assembly 6. Stirring rod 3 on rotating shaft 2 rotates accordingly, and stirring paddle 33 stirs the asphalt. The acute angle formed by mounting plate 32 and the front, as well as the curved stirring part 332, enhance the stirring effect. The rounded corners of the stirring paddle reduce damage to the asphalt and wear. During storage, the condition inside the tank can be observed through auxiliary port 12. When discharge is required, discharge valve 14 is opened, and asphalt flows out from discharge port 13. Transmission protective cover 8 protects transmission assembly 6 from external interference, ensuring stable stirring process.
