Description

Technical Field

[0001] The utility model relates to the technical field of hot asphalt paving, in particular to an emulsifying mill for hot asphalt paving processing. Background Art

[0002] Asphalt refers to a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives in liquid, semi-solid or solid state. In the process of hot paving of asphalt, the asphalt that has been heated and stirred at high temperature must be emulsified before being spread on the ground. Therefore, an emulsifying mill for hot paving asphalt is needed.

[0003] For this purpose, the Chinese patent with the publication number CN216654124U discloses an emulsified mill for hot-laid asphalt processing, including a base, an emulsified bin, a heat-insulating seat, a feed chamber, a reflux chamber, a rotating shaft, a spherical moving grinding disc, a spherical static grinding disc, a grinding space, a reflux bin, and a reflux pipe. The reflux pipe is connected to the reflux bin, and a connecting pipe is connected to the upper end of the reflux bin. One end of the connecting pipe is connected to the reflux port installed on the emulsified bin, and the reflux port is connected to the feed chamber. A conveying mechanism is provided in the reflux bin, and the rotating shaft is driven to rotate by a transmission mechanism. By setting a heat-insulating seat and filling the heat-insulating seat with heat-insulating material, a certain temperature can be maintained during asphalt emulsification to reduce temperature changes. In addition, by setting a spherical moving grinding disc and a spherical static grinding disc, the grinding working surface of the spherical moving grinding disc is basically a spherical surface. Compared with the prior art, the grinding working surface of the spherical moving grinding disc is increased, thereby improving the grinding efficiency.

[0004] However, in this patent, since the spherical movable grinding disc is far away from its transmission mechanism and there is no positioning device on the top of the spherical movable grinding disc, the spherical movable grinding disc may shake during the process of grinding the asphalt in the process of emulsifying asphalt, which will change the grinding gap between the spherical movable grinding disc and its emulsification bin, making it impossible to grind the asphalt evenly, making it impossible to emulsify the asphalt evenly, and making the asphalt emulsification efficiency low. In addition, in this patent, after emulsifying the asphalt, when the emulsified asphalt is discharged, part of the emulsified asphalt will remain on the inner wall of the emulsification bin and the outer surface of the grinding disc to a certain extent. Since there is no scraping device on the top of the grinding disc, it is impossible to scrape the part of the emulsified asphalt remaining on the inner wall of the emulsification bin and the outer surface of the grinding disc to the bottom to a certain extent, which will make it impossible to discharge the part of the emulsified asphalt remaining on the inner wall of the emulsification bin and the outer surface of the grinding disc, resulting in high loss of emulsified asphalt.
