[0002] Asphalt mixers are equipment for heating asphalt and mixing sand and gravel. They are usually equipped with wheeled chassis and used to repair asphalt pavement. The molten asphalt discharged during operation is often accompanied by a lot of smoke, which is composed of aerosols and vapors produced by the heating of asphalt and the combustion of asphalt-containing substances. Asphalt smoke is generally mixed with a certain concentration of smoke, and is brown or black in color, with a strong irritating effect. In addition, asphalt smoke contains a variety of polycyclic aromatic hydrocarbons such as benzopyrene, benzanthracene, and carbazole, most of which are carcinogenic and strong carcinogenic substances. However, the current asphalt mixers do not have the ability to collect and shield asphalt smoke, so those skilled in the art propose a solution for an asphalt mixer. Utility Model Content
