[0002] Asphalt, as an important road construction and waterproofing material, directly depends on the degree of uniform mixing of its components during the production process. In the production of high-value-added asphalt products such as modified asphalt and emulsified asphalt, it is necessary to efficiently and precisely mix and disperse additives such as polymer modifiers, stabilizers, and emulsifiers with the base asphalt. The quality and efficiency of this mixing process have a decisive impact on the storage stability, road performance, and service life of the final product.

[0003] Currently, the mixing and dispersing device is a core component in asphalt production equipment. Traditional mixing devices mostly adopt simple paddle or turbine structures, and the dispersion disc structure of traditional mixing devices is fixed, making it difficult to flexibly adjust the shear and mixing intensity according to different material characteristics. At the same time, their complex structure has many dead corners, making it extremely inconvenient to clean residual materials when changing formulas or batches, and posing a risk of cross-contamination.

[0004] Therefore, it is necessary to invent a dispersion mixing device for asphalt production to solve the above problems. Utility Model Content

[0020] Specifically, the slot 46 and the block 442 are positioned in the same location and have a T-shaped cross-section. The mating ring 441 is mated to the top of the support ring 45.

[0021] Specifically, the dispersion plate assembly 43 includes a fixing seat 431 fixed to one side of the top of the dispersion hole 42. The fixing seat 431 is provided with a rotating hole 432.

A positioning seat 435 is installed at one end of the fixing seat 431. One end of the rotating shaft 433 passes through the positioning seat 435, and a tightening nut 436 is provided on the outer wall of the end of the rotating shaft 433.

[0022] Specifically, one end of the rotating shaft 433 is provided with a limiting ring 437, and the other end is provided with a thread that matches the tightening nut 436.
