Those skilled in the art can also set the first heating component 15 and the first heat-conducting device 16 to other structures, as long as they can provide the required heat for the asphalt in the center of the development tank 1. The temperature monitoring device 7 can use a thermometer to monitor temperature changes in real time to ensure the safety and accuracy of the operation.

[0035] A second heat-conducting device 11 is fixedly connected to the development tank 1, and a second heating component 10 is provided in the second heat-conducting device 11; one end of the second heat-conducting device 11 is connected to a temperature sensor 8, and the temperature sensor 8 is filled with a temperature-regulating liquid 9. In this embodiment, the second heat-conducting device 11 is an oil pipe, and the second heating component 10 is heat-conducting oil. The oil pipe is fixed along the tank wall of the development tank 1, and the oil pipe is filled with heat-conducting oil to provide heat for the asphalt development process.

Those skilled in the art can also set the second heating component 10 and the second heat-conducting device 11 to other structures, as long as they can provide the required heat for the asphalt in the development tank 1.

[0036] There are several baffles 22 evenly distributed along the circumference of the inner wall of the development tank 1. The baffles 22 are embedded and welded in the development tank 1. In this embodiment, four baffles 22 are provided. The baffles 22 cooperate with the main impeller 3 and the auxiliary impeller 4 to form turbulence in all directions in the development tank 1. The convection circulation capacity and turbulent diffusion capacity are enhanced, the shear force and mixing efficiency are improved, and the asphalt can be ensured to be fully and quickly stirred, so that the solid-liquid mixing is more uniform, thereby greatly improving the reaction rate and mixing effect of the asphalt.

[0037] The growth tank 1 is also provided with a feed port 12, a discharge port 13, and an exhaust pipe 23. The inner wall of the discharge port 13 is provided with several sets of limiting posts 17. These limiting posts 17 are welded to the inner wall of the discharge port 13 and adhere closely to it, ensuring a smooth and stable discharge process. In this embodiment, the feed port 12 and exhaust pipe 23 are embedded in the top of the growth tank 1, while the discharge port 13 is embedded in the center of the bottom of the growth tank 1. The discharge port 13 is coaxial with the growth tank 1, and two sets of limiting posts 17 are provided.

[0038] To facilitate operation and adjustment of the growth tank 1, several movable devices 21 are movably connected to the bottom of the growth tank 1. Several support devices 19 are fixedly connected to the bottom of the growth tank 1 on both sides. Each support device 19 is equipped with at least one adjustment device 20. The support devices 19 and the adjustment devices 20 cooperate to adjust the height of the growth tank 1 from the ground. In this embodiment, four support devices 19 are provided, each equipped with an adjustment device 20. The support devices 19 are specifically support rods, and the adjustment devices 20 are specifically threaded rods. The support rods and the adjustment devices 20 are threadedly engaged with the threaded rods. When the growth tank 1 needs to be moved, the threaded rods are rotated to raise the support rods and move them away from the ground. The movable devices 21 then support the growth tank 1. The growth tank 1 is then moved by controlling the movable devices 21. When the growth tank 1 is moved to the desired position, the threaded rods are adjusted to lower the support rods and move the movable devices 21 away from the ground. The support rods now support the growth tank 1 and allow stirring. In this embodiment, four movable devices 21 are movably connected to the bottom of the growth tank 1. The movable devices 21 are specifically roller structures. In order to facilitate the adjustment of the positional relationship between the fixed adjustment device 20 and the supporting device 19 , at least one limiting device 18 is connected to each supporting device 19 . The limiting device 18 in this embodiment is a limiting block.

[0039] In order to facilitate the control of the stirring device 2 of the present invention, the motor 5 and the heater 6 are further electrically connected to a control switch 14 .

[0040] The setting of the baffle 22 of the utility model helps to maintain uniform flow of materials during the mixing process. Combined with the main impeller 3 and the auxiliary impeller 4, the mixing effect and work efficiency are further improved. The setting of this structure can improve the overall working performance of the equipment and extend the service life of the equipment to a certain extent.

[0041] The main impeller 3 of the present invention is located at the lower end of the auxiliary impeller 4. When the two are working, they can simultaneously perform longitudinal stirring and transverse stirring, so that the modified asphalt in the development tank 1 can circulate up and down. With the cooperation of the baffle 22, turbulence in all directions is formed in the development tank 1, thereby bringing higher shear force and mixing efficiency, making the solid-liquid mixing more uniform, and effectively improving the reaction rate and mixing effect; the second heat-conducting device 11 of the present invention provides heat to the side and bottom of the development tank 1 through the second heating component 10, and the first heat-conducting device 16 cooperates with the first heating component 15 to provide heat to the stirring device 2 to ensure that the temperature inside the development tank 1 is balanced, that is, whether it is the asphalt close to the wall of the development tank 1 or the asphalt in the center of the development tank 1, both can be well developed, avoiding the phenomenon that the temperature of the asphalt in the middle of the development tank 1 is too low and the temperature on the side of the wall of the development tank 1 is higher at the same time. Combined with the temperature sensor 8 and the temperature monitoring device 7, it can effectively prevent the asphalt from being excessively aged. Through the dual effects of stirring and heating, the uniform development of the modified asphalt is ensured. It is particularly suitable for high-viscosity rubber / SBS composite modified asphalt. It can be quickly stirred evenly to produce higher quality finished products. It has significant application prospects and economic benefits in road construction and other industrial fields.

[0042] The working principle of this utility model:

[0043] When using the development tank stirring device of the present invention to stir materials, the power supply terminals of the motor 5 and the heater 6 are connected, so that the motor drives the stirring device 2 to rotate, thereby driving the main impeller 3 and the auxiliary impeller 4 to rotate. With the cooperation of the baffle 22, horizontal stirring and vertical stirring are performed simultaneously, generating a turbulent effect, so that the materials in the development tank can be fully mixed. While stirring, the first heating component 15 provides balanced heat to the center of the development tank, and the second heating component provides balanced heat to the tank wall of the development tank 1. The temperature sensor 8 monitors the temperature of the second heating component 10 in real time and adjusts the temperature through the temperature regulating liquid 9, which promotes better fusion of the materials while preventing excessive aging, thereby improving the reaction rate and mixing effect of the materials.

[0044] When the development tank 1 needs to be moved, the support device 19 is raised by controlling the adjusting device 20 so that the support device 19 is away from the ground. At this time, the moving device 21 plays the role of supporting the development tank 1, and then the moving device 21 is controlled to move the development tank 1. When the development tank 1 is moved to a suitable position, the support device 19 is lowered by controlling the adjusting device 20 so that the moving device 21 is away from the ground. At this time, the support device 19 plays the role of supporting the development tank 1, so as to operate and adjust the position of the development tank 1.
