Description

[0002] In the process of road construction and use, a large number of discarded asphalt products will be generated. If they are landfilled, it will cause environmental pollution. With the continuous enhancement of people's environmental awareness and the rising price of asphalt raw materials, the asphalt recycling industry has developed rapidly. Asphalt pavement is affected by various natural factors and will gradually age over time. Aged asphalt will weaken the bonding force between asphalt and aggregate, causing the pavement particles to fall off and gradually expand, affecting the use of the road. Regeneration agent or asphalt with lower viscosity can be added to the aged asphalt for mixing and stirring to adjust the bonding degree of the aged asphalt, so as to achieve the purpose of improving the use function of asphalt. In the existing asphalt recycling devices, most of them directly stir the asphalt waste and additives. The large asphalt particles therein may have a negative impact on the stirring device and affect the mixing effect of the asphalt.

The device for reprocessing waste road asphalt admixture according to claim 1, characterized in that: The discharge assembly (6) comprises a second motor mounting seat (61), a discharge motor (62) is provided on the second motor mounting seat (61), a discharge roller (64) is provided in front of the discharge motor (62), a discharge screw propeller (65) is provided in the discharge roller (64), a second discharge port (66) is provided in front of the discharge roller (64), and a receiving port (63) is provided on the discharge roller (64) corresponding to the discharge pipe (312).

8. A method for reprocessing road waste asphalt admixture, characterized in that: The waste asphalt admixture reprocessing production device applied to any one of claims 1 to 7 has the following operation process: S1. Workers store the waste asphalt fragments that have completed the preliminary crushing process in the asphalt recovery device, and then the material transfer device transfers the asphalt fragments to the grinding assembly; S2, the asphalt enters the grinding assembly, and the grinding motor drives the grinding column to cooperate with the contact grinding frame to continuously and repeatedly realize relative movement. The friction generated by the contact between the two and the asphalt fragments grinds them into asphalt particles, which are screened by the vibrating screening assembly; S3, the asphalt particles after screening enter the mixing bin, and other types of powders and liquid additives are added to the mixing bin to fully mix with the waste asphalt particles, and then heated to obtain new asphalt that meets the use requirements; S4. The new asphalt is discharged from the reprocessing device into the discharge assembly, and the discharge motor drives the discharge propeller to discharge the new asphalt.
