Asphalt discharge outlet heat preservation device of asphalt distribution truck
The invention relates to the technical field of asphalt distribution, in particular to an asphalt discharge outlet heat preservation device of an asphalt distribution truck, which comprises an asphalt discharge pipe and two fixing sleeves, the fixing sleeves are arranged on the outer side of the asphalt discharge pipe, and the two fixing sleeves are sealed through a sealing strip. A ventilation chamber is formed in the fixing sleeve on one side; in the initial stage of asphalt discharging, the side, buried underground, of asphalt of the asphalt discharging pipe is cooled, the cooling speed of the asphalt is increased, meanwhile, when external gas flows into the device, water vapor is gathered through a storage strip, then the interior of a fixing sleeve is heated through the asphalt, a heating rod and a heating plate, and the cooling speed of the asphalt is increased. The gas in the fixing sleeve is switched to be in an internal self-circulation state, so that the heat preservation and heating effects of the device are improved, and meanwhile, the heat transfer efficiency in the device is improved at the initial heat preservation stage through water vapor.
本发明涉及沥青洒布技术领域，具体的说是一种沥青洒布车的沥青排放口保温装置，包括沥青排放管和固定套：所述沥青排放管的外侧设置有固定套，所述固定套设置有2个，且2个固定套之间通过密封条密封，一侧的所述固定套的内部开设有通风室；当沥青排放的初期来对沥青排放管沥青埋入地下的一侧进行降温，加快沥青的冷却速度，同时在外界气体流入到装置的内部时会利用储存条来对水蒸气进行聚集，之后利用沥青、加热棒和加热板来对固定套的内部进行加热，使得固定套内的气体切换为内部自循环状态，从而增加装置的保温加热效果，同时会利用水蒸气在保温初期增加装置内热传递的效率。
