Asphalt concrete preparation system

Abstract

The invention relates to an asphalt concrete preparation system. The asphalt concrete preparation system comprises a supporting seat, a stirring mechanism and a turnover mechanism, wherein the supporting seat is of a box body structure with an upward opening, the stirring mechanism is arranged in the middle of the supporting seat, and the turnover mechanism is installed at the lower end of the stirring mechanism. The asphalt concrete preparation system can solve the problems that when an existing asphalt concrete preparation device is used for feeding asphalt raw materials, asphalt cannot be heated and emulsified, the asphalt raw materials and concrete raw materials cannot be thoroughly and uniformly stirred, the grading ratio of the asphalt to concrete is influenced, then the viscosity ofthe formed asphalt concrete is influenced, the inner wall of a stirring kettle cannot be scraped and cleaned in time, stirring blades are prone to adhering to solidified asphalt, so that a thick asphalt layer can be accumulated after long-time use, the stirring quality of the asphalt concrete is influenced, the stirring and mixing efficiency is low, and the use quality of the asphalt concrete isinfluenced.

Description

technical field [0001] The invention relates to the technical field of asphalt concrete, in particular to an asphalt concrete preparation system. Background technique [0002] Bituminous concrete (bituminous concrete), commonly known as bituminous concrete, is artificially selected mineral materials with a certain gradation, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., and a certain proportion of road asphalt materials. A mixture prepared under controlled conditions. The strength of asphalt mixture is mainly manifested in two aspects. One is the cohesive force of the cement formed by asphalt and mineral powder; the other is the internal friction resistance and locking force between aggregate particles. The huge surface area of ​​fine mineral powder makes the asphalt material form a film, thereby improving the bonding strength and temperature stability of the asphalt material; while the locking force is mainly generated between the coarse aggr...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing asphalt concrete preparation device cannot heat and emulsify the asphalt when putting in the asphalt raw material, and cannot thoroughly mix the asphalt raw material and the concrete raw material evenly, which affects the grading ratio of asphalt and concrete, and further affects the viscosity of the formed asphalt concrete It can also solve the problem that the existing device for preparing asphalt concrete cannot scrape and clean the inner wall of the mixing tank in time, and the mixing blades are easy to adhere to the solidified asphalt, resulting in the accumulation of a thick asphalt layer after long-term use, which affects the mixing of asphalt concrete Quality, mixing efficiency is low, affecting the use quality of asphalt concrete
