[0017] Example 1, by Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The present invention relates to a device for preparing asphalt restoration modified emulsion, comprising a cylinder 1, a control switch 2 fixedly installed on the outer side of the cylinder 1, an arc-shaped heating plate 3 uniformly fixedly installed on the inner wall of the cylinder 1, a feed valve 4 fixedly installed on the top of the cylinder 1, a discharge valve 5 fixedly installed on the bottom of the cylinder 1, an emulsion shearing assembly 6 installed inside the cylinder 1, the top of the emulsion shearing assembly 6 extending to the top of the cylinder 1, and four support rods 20 symmetrically fixedly installed on the bottom of the cylinder 1, and a circular support base plate 21 fixedly installed on the bottom of the four support rods 20.

[0018] The emulsion shearing assembly 6 includes a drive shaft 7, the bottom of which is rotatably connected to the bottom of the inner part of the cylinder 1. The top of the drive shaft 7 extends through and to the top of the cylinder 1. A lower strip plate 8 is fixedly installed inside the cylinder 1 on the outer side of the bottom end of the drive shaft 7. Three positive shearing plates 9 are fixedly installed on the top of the lower strip plate 8 on both sides of the drive shaft 7. A drive sleeve 10 is installed inside the cylinder 1 on the outer side of the top end of the drive shaft 7, with the top of the drive sleeve 10 extending through and to the top of the cylinder 1. Connecting bearings 11 are fixedly installed at both the top and bottom of the drive sleeve 10, and the drive shaft 7 is rotatably installed inside the connecting bearings 11. An upper strip plate 12 is fixedly installed inside the cylinder 1 on the outer side of the drive sleeve 10. Three negative shearing plates 13 are fixedly installed at the bottom of the upper strip plate 12 on both sides of the drive sleeve 10. The six reverse shear plates 13 and six forward shear plates 9 are staggered. A housing 14 is fixedly installed at the top center of the cylinder 1. The top of the drive shaft 7 extends into the housing 14 and is rotatably connected to the top of the housing 14. The top of the drive sleeve 10 extends to the bottom of the housing 14. A drive motor 15 is fixedly installed at the top of the housing 14. The output shaft of the drive motor 15 passes through the top of the housing 14 and is fixedly connected to the top of the drive shaft 7. An active bevel gear 16 is fixedly installed inside the housing 14 and outside the drive shaft 7. A transmission bevel gear 17 is meshed with the outer side of the active bevel gear 16. A positioning shaft 18 is fixedly installed on one side of the transmission bevel gear 17 and is rotatably connected to the inner wall of the housing 14. A driven bevel gear 19 is meshed with the outer side of the transmission bevel gear 17 and is fixedly installed on the outer side of the top of the drive sleeve 10.

[0019] During use, the interaction of the cylinder 1, control switch 2, arc heating plate 3, feed valve 4, discharge valve 5, and emulsion shearing assembly 6 facilitates thorough mixing and shearing of the emulsion during the preparation of asphalt restoration modified emulsion. This avoids problems such as uneven concentration and uneven particle size in certain areas, ensuring the performance and stability of the emulsion and thus achieving better practicality. Furthermore, the interaction of the support rod 20 and the circular support base plate 21 provides stable support for the cylinder 1 during use, ensuring stable operation of the device.

[0020] Working principle: During operation, material is fed into the cylinder 1 through the feed valve 4. Then, the arc-shaped heating plate 3 is activated by the control switch 2 to heat the material inside the cylinder 1. Simultaneously, the drive motor 15 is started, driving the drive shaft 7 to rotate. The drive shaft 7 drives the lower strip plate 8 to rotate, which in turn drives the positive shear plate 9 to move. At the same time, the drive shaft 7 drives the driving bevel gear 16 to rotate, which in turn drives the transmission bevel gear 17 to rotate. The transmission bevel gear 17 drives the driven bevel gear 19 to rotate, which in turn drives the drive sleeve 10 to rotate in the opposite direction outside the drive shaft 7. The drive sleeve 10 drives the upper strip plate 1 to rotate. 2. The upper strip plate 12 rotates in the opposite direction to the lower strip plate 8, and drives the anti-shear plate 13 to move in the opposite direction to the forward shear plate 9. Through the forward shear plate 9 and the anti-shear plate 13 moving in opposite directions, the emulsion is subjected to strong shearing, so that the emulsion achieves a thorough mixing and shearing effect. After the emulsion is sheared, the drive motor 15 and the arc heating plate 3 are turned off, and then the emulsion is discharged through the discharge valve 5. This allows the asphalt restoration and modification emulsion preparation device to facilitate thorough mixing and shearing of the emulsion during use, avoiding problems such as uneven local concentration and uneven emulsion particle size, ensuring the performance and stability of the emulsion, and thus facilitating better practicality.
