L-type scraper blade 8 is installed in inner wall of rotary drum, as shown in figure 3, reworked material has arrived at scraper area bottom, roller rotation at this time
While drive and be fixed on the scraper blade of inner wall and take up reworked material promotion, reworked material is automatically fallen off simultaneously when being promoted to top
It moves backward, forms material curtain in roller, the high-temperature hot-air air-flow generated by the fired heater at rear portion heats, and reworked material is mobile
4 are seen to after cooking area 102, inner wall of rotary drum does not have material scraping plate, stir-frying heating is carried out to asphalt using roller rotatory force, by
It is relatively high in the region flame kernel temperature, it is heated using the hot-air of flame outer ring, prevents the excessively high regenerative mixed of temperature
Bituminous concrete surface aging in material, the quality of asphalt mixtures after influencing regeneration.After regenerating mixture finally enters high-temperature region 103, cylinder
Discharge port is arranged at body lower part, the angle spent using 2-4 ° of roller itself, while by reworked material weight during roller rotary rolling

Fired heater 7 is mounted on the rear portion of roller, and flame hot wind is blown to the front inlet direction of roller, removes reworked material
The moisture inside contained, makes it dry temperature raising.Its principle are as follows: reworked material includes some Bituminous concrete surface, and heating process is necessary
It is slowly unable to thermal-flame to directly heat, has the danger of burning, and pitch transient heating will cause pitch aging again, physics
Index reduces, and influences the quality of regenerating mixture, and the rear portion that flame storage heater places roller is advantageous in that by the present invention,
Scraper area forms the strong Hot-blast Heating that material curtain utilizes flame end, does not carry out secondary damage to reworked material without flame, then
Raw material are moved to middle part and cook area, this region is in the front of flame, and centre of the drum position there is not flame, utilize roller in this region
Rotation, reworked material are in high temperature gas flow lower part, and reworked material carries out stir-frying heating, when into rear portion high-temperature region, again through roller rotation
Raw material are directly excluded from outlet at bottom, and flame of centre does not generate any influence to reworked material.
After roller mix, temperature 180 DEG C, mentions reworked material from original 60 DEG C -- 80 DEG C are sufficiently heated to 120 DEG C --

It goes up a slope in the traveling course of work and is automatically adjusted roller using gyroscope and automatic control device such as computer when descending
Angle carries out computer automatic adjustment using two hydrobooms being mounted below roller before and after subframe, remains roller
0-6% necessary to working in horizontal plane.
The middle lower portion position of roller is arranged in centre of the drum's angle adjustment fulcrum, carries out angle using front and back hydroboom
It adjusts, the principle in center are as follows: since roller is longer, when angle adjustment point is in front-rear position, on climb and fall road
When surface construction, the front of roller or rear portion rising height are very big, and national highway standard clear height is 4.5 meters, then generating apparatus cannot lead to
It crosses, while center of gravity being caused to move up, the decline of equipment safety stability.
It is that roller is in up and down ramp work progress, roller by the centrally-disposed advantage of roller angular adjustment point
Amplitude reduction is adjusted, reduces the 50% of rear and front end height, while reducing integral central, equipment is made to run more stable safety.
Fig. 5 is that regeneration unit works in level road, the gradient of regeneration roller and horizontal line holding 0-6%.
