Description

Technical Field

[0001] The utility model relates to the technical field of compound modified asphalt production, and specifically relates to a rubber-SBS compound modified asphalt stirring device. Background Technique

[0002] The emergence and application of SBS have improved the high and low temperature performance of asphalt and its mixtures, and to a certain extent, delayed the occurrence of asphalt pavement diseases. However, the high cost of SBS modified asphalt and its less-than-ideal anti-aging ability are obvious deficiencies. As a large number of waste rubber tires, as automotive consumables, are difficult to dispose of after being scrapped, bringing huge pressure to the environment. Processing waste tires into rubber powder and adding it as a modifier to asphalt can achieve good results: rubber powder can significantly increase the viscosity of asphalt, and due to its large elasticity, adding it to asphalt can increase the proportion of elastic components in asphalt, enabling better recovery of asphalt under load deformation, improving the high temperature performance and anti-fatigue performance of asphalt. And because of its high damping and vibration reduction characteristics, it can also reduce road surface driving noise. Since it is difficult to further improve the performance of asphalt by modifying it with SBS and rubber powder alone, and it gradually cannot meet the current higher requirements for asphalt pavements. Therefore, in this paper, rubber powder and SBS are compound modified to make their advantages and disadvantages complementary, and the dosage of rubber powder is further increased in the compound modified asphalt, in order to maximize the modification effects of SBS and rubber powder, and further improve the performance of asphalt and its mixtures to meet higher requirements. However, during the processing of compound modified asphalt, the viscosity is too high, which poses higher-end requirements for the mixing equipment.

[0003] As disclosed in the authorized announcement number CN217164002U, a rubber-SBS compound modified asphalt stirring device is disclosed, which solves the problem that in the prior art, when stirring a modified asphalt mixture, it is carried out by a traditional mixer, and the mixture in the upper and lower parts of the stirring rod often cannot be evenly stirred, and at the same time, the mixture at the bottom cannot be stirred, thus greatly affecting the stirring rate of the modified asphalt. A rubber-SBS compound modified asphalt stirring device includes a box body, and a rotating rod is rotatably connected to the upper part inside the box body, and a driving motor is fixedly connected to the top of the box body through bolts. The method proposed in the utility model can fully stir the materials inside the box body through the simultaneous rotation of the stirring blades and mixing rods on the stirring rod, avoiding the problem that the mixture at the bottom cannot be stirred, thus greatly affecting the stirring rate of the modified asphalt. However, it is not convenient to move and unload during use. Therefore, we propose a rubber-SBS compound modified asphalt stirring device. Content of the Utility Model
