With the rise of our country's economy and state, our country's highway traffic has also entered a period of rapid development, with the growth of all kinds of road repair. Under this background, many asphalt pavement thermal regeneration repair equipments with high technological content emerged. The hot air asphalt regeneration repair vehicle for asphalt pavement directly heats the asphalt pavement and repairs it with the original asphalt mixture.

Advantages of hot-air regenerative repair vehicles

1. The hot air stove of the independent heating system directly connects the heating device, the intermediate link is greatly reduced, and the heating furnace can be started at any time as required, convenient, fast, and energy-saving.

2. The structure of the asphalt pavement heating wall is simple, light weight, left and right two heating boxes are equipped with separate heating wall hot blast stove. According to the size of the damaged area of ​​the road, the number of hot blast stoves on the heating wall can be flexibly controlled and started. The heating speed is fast, energy consumption is reduced, heat loss is reduced, and work efficiency is high.

Hot air furnace work process

The feeding device loads the bituminous concrete recovered from the road surface into the asphalt concrete heating and regenerating device. When the asphalt concrete needs to be heated, the electronic control system instructs the combustion controller on the hot stove to start the hot blast stove. The hot air generated in the hot blast stove is forcibly delivered to the asphalt concrete heating hot air ejector, and the hot air is directly sprayed onto the asphalt concrete located below the asphalt concrete heating and regenerating device by the oblique jet nozzle on the asphalt concrete heating hot air ejector. Fast, high heat utilization.

2. Work process of a heated wall stove

When the asphalt pavement heating wall needs to work, the control system instructs the combustion controller on the heating wall hot blast furnace so that the heating wall hot blast furnace starts working. The hot air is forced through the outlet of the hot blast stove to the heated wall hot air jet and then jetted directly onto the asphalt pavement. At this moment, the asphalt pavement heating wall heats the ground at the most suitable distance. The air inlet on the blower connected with the heating wall cover sucks the hot air in the heating wall hood and sends it back to the outlet of the hot blast stove to form an asphalt road surface. Heating wall hot air circulation system to avoid the loss of heat.
