Description

Technical field [0001] The invention relates to an asphalt pavement hot regeneration repair equipment, in particular to a hot air circulation type regeneration repair vehicle. Background technique [0002] With the rapid development of road traffic, the workload of road repairs has also increased rapidly. Various mechanized and automated asphalt pavement hot regeneration repair equipment have emerged as the times require. For example, asphalt pavement regeneration repair vehicles directly heat the asphalt pavement. And directly use the asphalt mixture of the original pavement to repair. The key component of this asphalt pavement regeneration repair vehicle is a heating device that provides sufficient heat for the pavement that needs to be repaired. The heating device should meet the requirements of the original Pavement asphalt mixture and recycled old pavement asphalt mixture provide as much heat as possible, because the heat that can be transferred to the asphalt pavement in a ...

Chinese patent 97236446.3 discloses a regeneration heating device for asphalt pavement, which includes a mixing cylinder, a pressure regulating valve, a permanent flame head, a pressure reducing valve, an air distribution pipe, an air switch, an air inlet at the side of the wall, an electrical control box, etc., the asphalt pavement The regenerative heating device uses gas to pass through the heating bricks and then ignites through the permanent flame to generate radiant heat. The structure of this device is complex, and the heating wall with the heating bricks is heavy. The road surface can only be heated after the heating bricks are preheated. The speed is slow, the energy consumption is large, the cost is high, and the temperature cannot be accurately controlled. A hot-air type asphalt pavement thermal regeneration repair vehicle disclosed in Chinese patent 200820012337.4 is equipped with a hot-blast stove, which is connected with a hot-blast distributor. The hot air distributor supplies the hot air in the hot air stove to the asphalt concrete heating regeneration device and the asphalt pavement heating wall respectively through the hot air pipeline. Since the hot air pipe always loses more or less heat while transferring heat, and the The distance between the hot blast stove and the heating wall of the asphalt pavement is relatively large, so the heat loss is large, and the heating speed is not ideal
