Description

Technical Field

[0001] The utility model relates to the technical field of asphalt concrete processing equipment, in particular to an asphalt premix batching heating device. Background Art

[0002] Asphalt premix, also known as asphalt concrete, is a composite material made of asphalt, gravel, sand and other materials pre-mixed in a concrete mixing plant;

[0003] Asphalt premix is ​​mixed by asphalt mixing and stirring equipment. In the mixing equipment, the dried aggregate and asphalt are fully stirred and mixed. At the same time, the heating equipment ensures that the mixing process is carried out at a high temperature to fully fuse the asphalt and aggregate. However, after the asphalt concrete mixture is discharged, the asphalt component in the asphalt concrete has strong adhesion. After the mixing is completed, some materials may adhere to the inner wall of the container and are difficult to discharge completely. If a scraper structure is provided on the stirring mechanism to adhere to the inner wall of the stirring container to achieve the function of preventing material residue, when the stirring mechanism stirs the asphalt concrete in the stirring container, the scraper will continue to rub against the inner wall of the stirring container, which will increase the noise during equipment operation. At the same time, it will also cause continuous wear on the scraper and the inner wall of the stirring container. If things go on like this, it will lead to a reduction in the service life of the stirring container and the scraper. Utility Model Content
