Preparation and processing technology of modified asphalt

Abstract

The invention belongs to the field of modified asphalt processing, and particularly relates to a modified asphalt preparing and processing technology which comprises a device shell, a storage box is connected to the top of the device shell through screws, a discharging hole is formed in the bottom of the storage box in a penetrating mode, and a grinding and smashing assembly is installed in the device shell. A mixing barrel is fixedly welded to the bottom of the device shell, an efficient mixing assembly is installed in the mixing barrel, a mounting plate is fixedly welded to the mixing barrel, an electric heating pipe is installed in the mounting plate through bolts, and a conveying pipe is connected to the bottom of the mixing barrel through bolts. The problems that an existing modified asphalt preparing and processing device can only conduct single mixing and stirring work on asphalt raw materials and modified materials, can only conduct single-state stirring during stirring, cannot conduct multi-state efficient stirring on the asphalt raw materials with large viscosity, and is poor in stirring efficiency are solved. The high efficiency and the thoroughness of the subsequent mixing and stirring work cannot be ensured.

Description

technical field [0001] The invention relates to the field of modified asphalt processing, in particular to a modified asphalt preparation and processing technology. Background technique [0002] With the rapid growth of my country's highway traffic construction, road transportation is becoming more and more busy, and the asphalt pavement has serious diseases such as rutting, cracking, and potholes. In order to comprehensively improve the performance of asphalt pavement, the use of modified asphalt is one of the effective measures. During the preparation and processing of modified asphalt, it is necessary to modify rubber, resin, high molecular polymer, ground rubber powder or other fillers. Adding materials to asphalt raw materials, combined with the use of preparation and processing equipment for melting, stirring and mixing, the performance of asphalt or asphalt mixture can be improved, and modified asphalt can be obtained. However, some processing devices for the preparat...

AI Technical Summary

Problems solved by technology

[0003] Conventional processing devices can only perform a single mixing and stirring work on asphalt raw materials and modified materials, and when stirring, they can only perform single-state stirring, and cannot perform multi-state high-efficiency mixing on viscous asphalt raw materials. Stirring, which cannot ensure the efficiency and thoroughness of the subsequent mixing and stirring work, and the conventional processing device cannot perform stable and efficient grinding and crushing of the modified material with large particles during the working process, and thus cannot guarantee the subsequent melting and mixing work It is stable and efficient, and at the same time, it cannot automatically clean the modified asphalt sticking to the inner wall of the device, which is poor in practicability. Therefore, it is necessary to provide a modified asphalt preparation and processing process to meet the needs of users.
