In the asphalt heating tank, a plurality of support rods are arranged between the inner tank and the outer tank.

In the asphalt heating tank, the diameter of the inner tank is 1.5-1.8m, the height of the inner tank is 2-2.5m, the horizontal upward distance between the inner tank and the outer tank is 3-5cm, the thickness of the connecting rod is 4-5mm, the width of the connecting rod is 10-12cm, and the inclination angle of the scraping blade is 45 degrees.

Compared with the prior art, the asphalt adhered to the inner tank is scraped by the scraper, so that the recovery rate of the asphalt is improved, the recovery rate can reach more than 98%, and is improved by more than 5%. According to the invention, the heat conduction oil is arranged between the inner tank and the outer tank, and the heat of the heater is uniformly transferred into the inner tank through the heat conduction oil, so that the heat conduction area is large, and the heating efficiency is high. Drive the pitch that the doctor-bar will bond on inner tank wall through the (mixing) shaft and scrape down, make being heated of pitch more even, not only can improve heating efficiency, avoid being close to the pitch of inner tank wall in addition and continuously being heated fast and the pyrolysis, reduce the production of pitch cigarette, avoid workman's poisoning, the security is high. In addition, the scraping blade continuously scrapes the inner tank, so that asphalt hardening is not easy to occur on the inner tank, frequent maintenance is not needed, and the maintenance frequency is low. Therefore, the invention has the advantages of high asphalt recovery rate, high heating efficiency, high safety and low maintenance frequency.
