Description
Technical field
The invention belongs to concrete stirring technique field, be specifically related to a kind of asphalt mixture regenerating heating stirring roller.
Background technology
Flexible pavement is the main type of road, accounts for the 70-80% of pavement of road, along with wearing out gradually of pavement asphalt, cohesion and intensity descend gradually, finally can cause asphalt concrete pavement wheel paths to occur, wave, the crack, hole groove, phenomenon such as disperse, can not satisfy automotive safety, comfortable, economy is quick, travel require the time, will road pavement overhaul or reconstruct.Flexible pavement overhaul and the reconstruction process in will produce a large amount of waste and scraps, wherein waste asphalt mixture includes rubble, and the aged asphalt about sand and 3-4% is if no longer utilize it directly discarded, not only cause the waste of resource, also can become the groundwater pollution source.The prior art of utilizing for waste asphalt mixture generally is to adopt milling machine that the flexible pavement milling is granulated earlier and bulk, granular or block waste asphalt mixture being broken into could be by the regeneration of regeneration corollary equipment behind the granule again, this asphalt pavement regeneration mode, because granular through being broken into, cost is higher, and original grating is destroyed, powder increases, the part aggregate size reduces, thereby has to carry out re-using behind the sieve classification, has increased use cost greatly.
Summary of the invention
Above-mentioned defective at the prior art existence, it is reasonable that the object of the invention provides a kind of compact conformation, the heat exchanger effectiveness height, waste asphalt mixture need not pass through second-time breakage, can directly carry out thermal regeneration, the asphalt mixture regenerating heating stirring roller that the bituminous mixture after the regeneration can directly utilize to block waste asphalt mixture.
For achieving the above object, the technical solution used in the present invention is: this asphalt mixture regenerating heating stirring roller has the rolling stand of inclination, rolling ring, cylinder, drum drive, rolling ring is sleeved on the cylinder and by the roller on the rolling stand and supports, drum drive cooperates driving with rolling ring, cylinder be provided with burner than low side, the cylinder of burner bottom is provided with discharging opening, the other end of cylinder is provided with charging aperture, the cylinder on charging aperture top is provided with the outlet of cigarette wind, inner wall of rotary drum is provided with stirring vane, it is characterized in that: the cylinder that is positioned at feed inlet end is set with sifting barrel, interior sifting barrel is fixedlyed connected with cylinder, the periphery wall of sifting barrel is made of Screening Network in described, the medial end shutoff of interior sifting barrel has annular filter screen, described charging aperture is connected with interior sifting barrel, and the cylinder that is positioned at port of export burner below is provided with the pitch jet pipe.
The Screening Network of sifting barrel is made of three grades of Screening Networks from outside to inside in described, the aperture of outermost one-level Screening Network is 80mm * 80mm～110mm * 110mm, the aperture of the secondary Screening Network at middle part is 60mm * 60mm～80mm * 80mm, and the aperture of three grades of terminal Screening Networks is 40mm * 40mm～60mm * 60mm.
Be surrounded with profile of tooth lifting blade and spiral resistance material blade on the inner wall of rotary drum of described one-level Screening Network correspondence, be surrounded with on the inner wall of rotary drum of described secondary Screening Network correspondence and extricate from stock column more, the end of extricating from stock column extend in the interior sifting barrel more, is surrounded with the profile of tooth lifting blade on the inner wall of rotary drum of secondary Screening Network correspondence; Be surrounded with on the inner wall of rotary drum of described three grades of Screening Network correspondences and extricate from stock column more, in the end of extricating from stock column extend into more in the sifting barrel, on the inwall of the cylinder low side of three grades of Screening Network correspondences around the profile of tooth lifting blade is set.
The periphery of described burner flame area is provided with and hides the flame arc.
The discharge end of described cylinder is provided with feed box, and the bottom that is positioned at feed box is provided with agitator.
The cigarette wind outlet of described cylinder is connected with the airduct that flashes back, and the outlet of the airduct that flashes back is connected with the air intake of burner.
Adopt the beneficial effect of technique scheme to be: this asphalt mixture regenerating heating stirring roller is equipped with sifting barrel at the cylinder fixed cover that is positioned at feed inlet end, the periphery wall of interior sifting barrel is made of Screening Network, the medial end shutoff of interior sifting barrel has annular filter screen, and charging aperture is connected with interior sifting barrel.When waste asphalt mixture is regenerated, need not pass through second-time breakage, in can be directly the waste asphalt mixture of bulk directly being joined in the sifting barrel, interior sifting barrel is along with the cylinder of outside rotates together, burner is when heating, make waste asphalt mixture progressively softening, separate, the Screening Network of interior sifting barrel periphery wall separates the block waste asphalt mixture of size, less waste asphalt mixture falls into cylinder inside by Screening Network, waste asphalt mixture is under the vexed mode of heating of this steaming, waste asphalt mixture is positioned at the upper position of cylinder in whole heating process, make be heated more even, the heat exchanger effectiveness height has kept the character of former compound substantially, avoids the ageing of asphalt problem that is caused by overheated; The cylinder that is positioned at the port of export is provided with the pitch jet pipe, can spray into pitch by the pitch jet pipe and mix according to the content of waste asphalt mixture medium pitch, makes the bituminous mixture medium pitch content of regeneration reach code requirement.The Screening Network of interior sifting barrel is made of three grades of Screening Networks from outside to inside, and isolated less waste asphalt mixture is separated in interior sifting barrel immediately, has improved the efficient of interchange of heat and the productive rate of cylinder.Inner wall of rotary drum is provided with profile of tooth lifting blade, spiral resistance material blade and material toggling post, to promote from isolated larger particles in the interior sifting barrel, stop than granule simultaneously and advance, prolong heating, broken time, the material toggling post clashes into fragmentation to the big waste asphalt mixture in cylinder and the interior sifting barrel simultaneously, has improved the heating separative efficiency.This asphalt mixture regenerating heating stirring roller has changed on a small scale, has hanged down the production model of energy rate, limited production, can carry out large batch of waste asphalt mixture cyclic regeneration, waste and old material need not pass through second-time breakage, reduced the breakage rate of cost of investment and aggregate, therefore need not add new material, the regeneration rate of waste and old material is reached more than 95%, can be directly used in secondary after the regeneration to get down the highway and the construction in place such as parking lot.
