[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It mostly exists in the form of liquid or semi-solid petroleum and has a black surface. At present, asphalt is generally heated in a heating tank. In order to heat the asphalt evenly, a stirring device is installed in the heating tank to stir the asphalt.

[0003] After searching, a Chinese patent with publication number CN219991492U discloses an asphalt heating device. Its technical solution includes: a bottom plate, a tank body, a heating ring plate and a baffle.
