The utility model relates to a device for heating and melting asphalt, and particularly relates to an asphalt melting device for carrying out melting on asphalt which is solidified into blocks in the building material industry. The device comprises a melting pipe with an inlet end and an outlet end, the outer wall of the melting pipe is provided with a first heating unit for heating the melting pipe, the outlet end is provided with a second heating unit for heating asphalt and preventing non-molten asphalt from rolling out of the melting pipe, and the second heating unit is provided with a gap part through which molten liquid asphalt flows out. According to the utility model, asphalt is heated and molten by using the melting pipe with a first heating unit on the wall thereof, and the heated part is restricted to asphalt in the melting pipe, therefore, the heated area is small, and the energy consumption is significantly reduced; the second heating unit can prevent non-molten asphalt from rolling out of the me
