Abstract

The invention provides a recycled asphalt heating device which comprises a rotary drum, a heater and an air guide and reflux device, wherein the rotary drum is provided with a material feeding end and a material discharging end; the heater is connected with the material feeding end and is used for injecting high-temperature gas into the rotary drum; the air guide and reflux device is arranged at the material discharging end of the rotary drum and is used for heating the outer wall of the material discharging end through the gas flowing out of the material discharging end. According to the recycled asphalt heating device provided by the invention, the air guide and reflux device is arranged at the material discharging end of the rotary drum, so that the air guide and reflux device can be used for guiding the gas discharged from the material discharging end to the outer side wall of the material discharging end of the rotary drum, to enable the gas discharged from the material discharging end to heat a material in the rotary drum again, and temperature reduction of the material discharging end of the rotary drum can be slowed down. Therefore, the phenomenon that the material is attached to the inner wall of the material discharging end of the rotary drum and a material raising device due to extremely low temperature is avoided, the forming quality of a material curtain is effectively enhanced, the heating efficiency of a product is improved, the cleaning period of the rotary drum is correspondingly prolonged, and continuous production of the product is guaranteed.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a recovery asphalt heating device. Background technique [0002] When recycling asphalt mixture for asphalt pavement, it is necessary to heat the asphalt mixture. At present, the reclaimed asphalt heating devices all contain main components such as heating devices and heating drums. In existing products, the heating device is usually installed at the feed end of the heating drum. When the asphalt mixture rotates in the heating drum and moves to the discharge end along the inner wall of the drum, the inner wall of the discharge end of the drum and the The occurrence of sticky material on the lifting device not only affects the quality of the material curtain and reduces the heating efficiency of the drum, but also requires workers to periodically clean up the sticky material, which affects continuous production and increases the use of users. The cost is not conduc...
