Modified asphalt is a mixture of asphalt and rubber to improve its waterproof properties, which is then used in the waterproofing field. During the processing of modified asphalt, it needs to be heated to melt it for later processing or use. This requires the use of a heating device. Most existing heating devices only have a heating effect and can only simply melt the raw materials inside.

[0003] A heating device for asphalt production with publication number CN216890801U has the following defects during use:

However, during actual use, when the asphalt is unloaded, in order to facilitate its outflow, the balance pipe will be opened to connect the internal and external air pressures, but at the same time, a large amount of external oxygen will enter, causing the high-temperature asphalt to contact with oxygen and water vapor, accelerating the aging of the asphalt and reducing the asphalt production efficiency. For this reason, we have proposed a heating device for asphalt production. Utility Model Content
