The virgin material feed well 101 for feeding smoke box 1 imports inner roller 204 through guide blade 203, and lifting blade 205 is along inner roller 204
Inner wall anchor ring aggregate lifted spill down again, material curtain is formed, so that aggregate and high-temperature flue gas carry out sufficient thermal convection.
When aggregate runs to construction materials contract vane region, construction materials contract blade 207 on the inner wall of inner roller 204, avoids aggregate packet
The flame contact of aggregate and burner 5 heats new aggregate by heat transfer, heat radiation and thermal convection, after drying heating
New aggregate lifts along cylinder anchor ring through discharge ring 208 and is discharged into the splicing groove 800 of new aggregate material-dividing groove 8.
When adding reworked material, as shown in figure 13, revolving door 801 is opened, and new aggregate is through splicing groove 800 and material-dividing groove 802
Enter the inner cylinder discharge port 209 of inner roller 204 afterwards, and then enters the drying heating of outer roller 302, while by outer roller 302
Reworked material feed well 303 be sent into reworked material, the new aggregate in reworked material and outer roller 302 after drying heating starches 211 in material toggling
Under the action of be sufficiently mixed, reworked material is heated by new aggregate heat transfer and barrel heat radiation mode, avoids asphalt-regenerating material
It is contacted with high-temperature flue gas, mixed mixture enters subsequent processing through mixture blow tank 300.
When not adding reworked material, as shown in figure 14, revolving door 801 is closed, and new aggregate discharges through material-dividing groove 802 and virgin material
After slot 803, into subsequent processing.
Wherein, material toggling slurry 211 on 204 outer wall of inner cylinder helically line arrange, make mixture during mixing along
Hand of helix is run to 300 direction of mixture blow tank.
At the same time, high-temperature flue gas is present in interior cartridge module 2, under the air inducing effect of equipment dust-extraction unit, inside and outside rolling
There are pressure difference, the interior a small amount of bitumen flue gas generated of outer roller 302 and bituminous dust to be discharged simultaneously from inner roller discharge port 209 for cylinder
It is again introduced into inner roller 204, when by 204 combustion zone of inner roller, is handled through burning；The influence to cloth bag, high temperature are not will cause
Flue gas enters equipment dust-extraction unit through the air inducing pipeline of the smoke box 102 and equipment dust-extraction unit that feed smoke box 1, avoids glance coal
Gas and bituminous dust concentration can dodge quick-fried security risk when reaching a certain level, while play the effect of environmental protection and energy saving.
