Highway asphalt oxidation treatment process
The invention belongs to the technical field of asphalt production, and particularly relates to a highway asphalt oxidation treatment process. According to the invention, an oxidation device used in the method comprises a base, two supporting plates are fixed at the top end of the base, an oxidation tank is fixed between the two supporting plates, a heating ring is arranged on the inner side wallof the oxidation tank, the heating ring is embedded into the inner side wall of the oxidation tank, a rotating shaft is rotationally installed between the two supporting plates and penetrates throughthe oxidation tank, and two or more shifting block sets are arranged on the side wall of the rotating shaft at equal intervals in the circumferential direction of the rotating shaft. According to theinvention, hot air is introduced into the oxidation tank, potassium permanganate is heated to generate a large amount of oxygen to improve the oxygen concentration of the hot air, and asphalt in the oxidation tank is fully oxidized, so that the highway asphalt oxidation treatment process is suitable for areas with low oxygen concentration in air, the application range of the process is widened, and the oxidation efficiency of the asphalt is further improved.
本发明属于沥青生产技术领域，具体的说是一种公路沥青氧化处理工艺，该方法中使用的氧化装置包括底座，所述底座顶端固定有两个支撑板，两个所述支撑板之间固定有氧化罐，所述氧化罐的内侧壁上设有加热环，所述加热环嵌入氧化罐的内侧壁内，两个所述支撑板之间转动安装有转轴，所述转轴穿过氧化罐，所述转轴侧壁上沿其周向等距离设有两个以上的拨块组；本发明通过对氧化罐内通入热空气，并通过对高锰酸钾进行加热使之产生大量的氧气来提高热空气的氧气浓度，使得氧化罐内的沥青得到充分的氧化处理，从而使得本发明适用于空气中氧气浓度低的地区，进而提高了本发明的适用范围，也进一步的提高了沥青的氧化效率。
