It closes.In existing hot in-place recycling, cold waste asphalt mixture be by multiple cold burden storehouses, belt conveyer, elevator, will be waste and old
Asphalt, which is sent directly into inside drying roller, carries out drying heating.
Presently, there are following problems for this material-uploading style: since hot-mix plant recycling equipment drying roller setting height is higher,
Often apart from drying roller feed end apart from farther out, the feeding time is longer in cold burden storehouse, leads to the extremely difficult control of feeding opportunity, if first
Feeding, burner start to light a fire again, once burner ignition fails, will lead to a large amount of cold waste asphalt mixtures and are admitted to drying
Roller, the cold waste asphalt mixture that drying roller is sent into this part can not directly participate in producing and using, it is necessary in time will regeneration
Cold waste asphalt mixture in equipment all can continue to produce after discharge, not only affect manufacturing schedule, and once into
The cold waste asphalt mixture for entering again generating apparatus is all discharged not in time, after being mixed with the hot material of subsequent heat, will generate
A collection of temperature is relatively low, and viscosity greatly regenerates hot material, adheres to drying roller barrel, hot material temporary storing bin, weigher, chute for increasing
Etc. the risk of multiple components, equipment failure rate is considerably increased, once sizing, putty occurs, will lead to equipment can not normally be transported
Turn；If burner is first lighted a fire, cold waste asphalt mixture is gone up after success to be fired again, at this point, from cold burden storehouse to drying roller
Distance farther out, once feeding is not in time, easily causes burner hearth and drums inside temperature to overstep the extreme limit temperature, not only there is windburns
Danger, and cause the waste of the energy.
