Problems solved by technology
The biggest problem with this process is that using far-infrared heating can easily accelerate the aging of asphalt pavement, and the heating depth is not enough, only about 40mm can be heated. Regeneration can only solve the problem of the asphalt surface layer, but the diseases caused by the middle and lower layers cannot be solved.

Embodiment Construction
[0034] Embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0035] Such as Figure 1-2 The shown heating and recycling equipment for asphalt waste and old materials, through the continuous delivery of asphalt waste and old materials, new aggregate, mineral powder, asphalt and regeneration agent, enter the rotating cylinder 3 from the feeding port 5, and produce The high-temperature flue gas exchanges heat through radiation and direct contact. Driven by the rotating cylinder 3 and the lifting plate 10 on the cylinder, it moves forward, tumbles, and stirs to form a finished product, which is fed on the drying drum 1. The finished product outlet 6 at the other end corresponding to the port 5 is discharged, and the high-temperature asphalt fume is discharged through the exhaust port.
[0036] The burner in the barrel 3 adopts a synthetic gas burner, which has the ...

The invention discloses asphalt waste material heating and regenerating equipment and a processing method thereof. An existing on-site pavement regenerating technology has the defects that aging of an asphalt pavement is prone to accelerate due to the fact that far-infrared ray heating is adopted, and the heating depth is insufficient. The asphalt waste material heating and regenerating equipment comprises a drying roller for asphalt waste materials and an asphalt flue gas incinerator installed at the periphery of the drying roller, the drying roller comprises a roller body, a burner installed on the roller body, a charging port located at one end of the roller body and a finished product discharging port located at the other end of the roller body, the burner is installed at one end of the drying roller, and the other end of the drying roller is provided with an exhaust port of high-temperature asphalt flue gas; the asphalt flue gas incinerator comprises an incinerator wall and two sets of regenerative burner nozzles installed on the incinerator wall, the incinerator wall wraps the drying roller in a surrounding mode, and a space formed between the incinerator wall and the drying roller serves as an asphalt flue gas incineration and circulation channel. According to the asphalt waste material heating and regenerating equipment, 100% regeneration of the asphalt waste materials can be achieved, and asphalt smoke generated in the asphalt waste material heating process can be automatically treated.
Description
technical field [0001] The invention relates to the field of heating and regeneration of waste asphalt materials, in particular to a heating and regeneration equipment for waste and old asphalt materials and a processing method thereof. Background technique [0002] Compared with cement pavement, asphalt pavement has the advantages of fast and convenient maintenance, good driving conditions, and coordination with the surrounding landscape. More and more highways and municipal roads use asphalt pavement, and asphalt pavement has accounted for more than 95% of domestic road mileage . [0003] As the asphalt pavement is used for a long time, different diseases will appear, which will cause the asphalt pavement to start to be damaged. The damaged asphalt pavement needs to be resurfaced after milling. The asphalt concrete milling material (asphalt waste material) produced every year is about 10 million tons, and with the increase of the number of asphalt pavement, this amount i...
