Description

Technical Field

[0001] The invention relates to the technical field of waste asphalt processing, and in particular to a processing device for recycling waste asphalt under a circular economy. Background Art

[0002] Asphalt pavement is usually used for the surface layer of paved roads. It is directly affected by vehicle loads and atmospheric factors. At the same time, the physical and mechanical properties of asphalt mixtures are greatly affected by climate and time factors. Therefore, in order to enable the road surface to provide stable and durable services to vehicles, asphalt pavement needs to be maintained after long-term use. Waste asphalt refers to the waste asphalt material generated during road construction and maintenance. The waste asphalt is processed and reused through recycling and processing equipment to ensure effective recycling.

[0003] There are still some problems in the use of existing processing devices for recycling and processing of waste asphalt. Before crushing the waste asphalt, the crushed particles need to be cleaned to remove dust and impurities. A large amount of water is required in the cleaning process, which causes a waste of water resources. In addition, when crushing after subsequent cooling, the crushing rod is easily affected by the friction during work and generates heat. When contacting with the waste asphalt, the heat is transferred to the cooled waste asphalt. The waste asphalt is easily sticky when heated, affecting the work. Therefore, those skilled in the art provide a processing device for recycling and processing of waste asphalt under a circular economy to solve the problems raised in the above background technology. Summary of the invention

The two hollow motors 19 drive the two crushing rods 13 to rotate for crushing. During the crushing process, the two first rotating joints 308 and the rotating ends of the two second rotating joints 309 cooperate to rotate, and the water flows through the two first rotating joints 308 into the first frame 305, and is filtered again through the filter net 307 inside the first frame 305 before entering the water storage tank 301. During the crushing process, the heat during crushing is taken away by the water flow, thereby preventing the waste asphalt from becoming sticky due to heat. Then the vibration screening machine 20 is started to separate the orthopedics and asphalt for subsequent use.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
