Description

Low-carbon asphalt mixing device for bridge construction Technical Field The utility model relates to the technical field of bridge construction, in particular to a low-carbon asphalt mixing device for bridge construction. Background Bridge is a structure which is generally erected on rivers, lakes and seas and can smoothly pass vehicles, pedestrians and the like. In order to adapt to the traffic industry of modern high-speed development, bridges are also spreading to span mountain stream, poor geology or buildings which are erected to meet other traffic requirements and are more convenient to pass, and low-carbon asphalt is required to be paved during bridge construction. As shown in a reference case of ' a mobile low-carbon asphalt mixing plant ' bulletin No. CN222390185U ', after an asphalt heating box conveys heated asphalt into an asphalt mixing tank, a stone feeding hopper can convey stones into the asphalt mixing tank, the asphalt mixing tank can stir asphalt and stones, but in the stirring process, the heated asphalt can continuously cool, the asphalt in the stirring process is sprayed with fire through a plurality of flame spraying heads, the flame size is controllable, the asphalt is ensured to be always stirred at the optimal temperature, and the condition that the asphalt becomes too viscous to be mixed is avoided. According to the reference materials, when the asphalt is conveyed to the asphalt stirring tank part and stirred and mixed with stones by the flame spraying heads in the device, the natural gas in the flame spraying heads is ignited by the flame spraying heads through the igniter, so that the flame inside the asphalt stirring tank is sprayed by the flame spraying heads, the flame can heat the asphalt inside the asphalt stirring tank, the condition that the asphalt is cooled in the stirring process is prevented from being in an optimal temperature range all the time, the condition that the asphalt is cooled in the stirring process is prevented from being sticky and difficult to stir is prevented, but when the device is used for stirring low-carbon asphalt, the stirring effect of the asphalt is not uniform, the stirring effect of the low-carbon asphalt is influenced, the low-carbon asphalt is not convenient to uniformly stir, and the using effect of the device is reduced.
