One, roller is heated
Heating roller 103 is mounted in asphalt pavement regeneration system, as shown in Fig. 2, regenerating device front collector 2013 will Asphalt collection after the loose machine heating rake pine of front heating rake, communicated band 2014 are promoted to the feed inlet of cylinder front, Into inner barrel, cylinder rotates 7 circles per minute --- and 12 circles, length is 5-15 meters, straight according to the regenerative mixed doses of processing Diameter is 1 meter -2.5 meters, and cylinder material is the manufacture of high temperature resistant steel plate edge rolling, and appearance installs insulating layer.Cylinder is mounted on subframe The front is high and the back is low, and angle is 2-4 °, and asphalt is made to discharge by gravity from cylinder rear portion during cylinder rotary rolling Mouth Self-discharged, the mix spreading machine to work independently for rear portion are ready;Fired heater is installed at body centre rear portion, is added The fuel of hot device is fuel oil and natural gas etc..
Two, the concrete operating principle of roller is heated
Heating roller 103 divides for three regions, and front is scraper area, and middle part is to cook area, rear portion high-temperature region simultaneously and Discharge port, such as Fig. 3 after reclaimed asphalt mixture enters roller by conveyer belt, are fixed on the channel-shaped inclination batch turning of inner wall of rotary drum Plate 205 imports drums inside, prevents material from overflowing from roller front, after reworked material is imported, into scraper area 2101.Scraper area 2101 are equipped with L-type scraper blade 208 in inner wall of rotary drum, as shown in figure 4, reworked material has arrived at scraper area bottom at this time, rolling The scraper blade for being fixed on inner wall is driven to take up reworked material promotion while cylinder rotation, reworked material is fallen automatically when being promoted to top It down while moving backward, forms material curtain in roller, the high-temperature hot-air air-flow generated by the fired heater at rear portion heats, regeneration After material is moved to and cooks area 2102, inner wall of rotary drum does not have material scraping plate, using roller rotatory force to asphalt carry out stir-frying plus Heat is heated using the hot-air of flame outer ring since the region flame kernel temperature is relatively high, prevents the excessively high regeneration of temperature Bituminous concrete surface aging in mixture, the quality of asphalt mixtures after influencing regeneration.Regenerating mixture finally enters high-temperature region 2103 Afterwards, discharge port is arranged at cylinder lower part, the angle spent using 2-4 ° of roller itself, while regenerating during relying on roller rotary rolling Expect that gravity, reworked material are voluntarily skidded off from roller rear portion discharge port 206, is ready for rear portion mixing machine spreading machine.
Fired heater 207 is mounted on the rear portion of roller, and flame hot wind is blown to the front inlet direction of roller, removal regeneration The moisture contained in material, makes it dry temperature raising.Its principle are as follows: reworked material includes some Bituminous concrete surface, and heating process must Thermal-flame must be slowly unable to directly heat, have the danger of burning, and pitch transient heating will cause pitch aging again, object Managing index reduces, and influences the quality of regenerating mixture, and the present invention exists the benefit at the rear portion that flame storage heater places roller In, scraper area forms the strong Hot-blast Heating that material curtain utilizes flame end, secondary damage is not carried out to reworked material without flame, Reworked material is moved to middle part and cooks area, this region is in the front of flame, and centre of the drum position there is not flame, utilizes rolling in this region Cylinder rotation, reworked material is in high temperature gas flow lower part, and reworked material carries out stir-frying heating, when into rear portion high-temperature region, rotates through roller Reworked material is directly excluded from outlet at bottom, and flame of centre does not generate any influence to reworked material.
