Description
Technical field:
The utility model relates to a kind of pitch process equipment, particularly relates to a kind of regenerating stirrer that is applied to produce bituminous concrete.
Technical background: at present, during a lot of highways of China have entered, the overhaul phase, 15-20 projected life of general bituminous paving, the bituminous paving 10% that need overhaul national every year, approximately to have high, the inferior high-grade bituminous paving of more than ten thousand kilometer of 3-5 need in, overhaul, the annual waste asphalt material that is produced will reach ten thousand tons of 1000-1500.These waste and old material are not only wasted ample resources as not carrying out regeneration, and will cause serious pollution to environment, therefore, the regeneration techniques of the waste and old material of promotion and application and equipment are the important behaves of saving energy and reduce the cost, can reduce the energy and raw-material consumption to greatest extent, reach economy and resource environment " doulbe-sides' victory " purpose.Recycled Asphalt Pavement is in heating, whipping process, distributing precision determines its performance, existing continous way rotary mixer, be mainly single roller frame, owing to limitation of design, add the naked light of the direct catalytic combustion device of waste and old material, make waste and old material heating inhomogeneous, and waste and old material medium pitch composition is local ageing under the condition of high temperature easily, thereby has influenced the serviceability of bituminous concrete.
The utility model content: the purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of regenerating stirrer for pitch concrete of new structure is provided, can finish virgin material heating, oven dry continuously and mixes with waste and old material, agitating procedure, the good Recycled Asphalt Pavement of formation grating.Have characteristics simple in structure, as to clear up convenience, long service life.
The utility model is achieved in that a kind of two-layer cylinder asphaltic concrete mixer, comprise base, the urceolus of band discharging opening, described base is provided with transmission device, described urceolus is arranged on the described transmission device, and can rotate with respect to base, is provided with paddle slurry group on the inwall of described urceolus, it is characterized in that: the coaxial line of described urceolus is provided with the inner core of an end band discharging vane group, also is provided with paddle slurry group on the inwall of described inner core; Described base is provided with inner core panel and urceolus panel, is set in described inner core and the urceolus end away from discharging opening, has charging aperture at described inner core panel and urceolus panel, has port in described inner core face plate center.
The utility model compared with prior art has following advantage:
1. the utility model is reasonable in design, the employing inner core heats virgin material and dries, and utilize the heat radiation of inner core that the waste and old material in the urceolus is heated, stirring mixes with both in the place at discharging opening, avoided in the waste and old material heating process naked light to the influence of pitch, prevented the aging of pitch composition effectively, improved the pavement performance of Recycled Asphalt Pavement, characteristics such as have compact conformation, thermal efficiency height, stir.
2. described urceolus panel is provided with air-introduced machine, so on the one hand the flue gas that is produced in the diesel combustion process is discharged, utilize high-temperature flue gas that the waste and old material in the urceolus is carried out reverse-flow heating on the other hand, further improve the efficiency of heating surface of waste and old material, energy savings.
3. because described inner core is arranged on the same axis of urceolus, make it stressed more reasonable, adopt one group of transmission device to drive simultaneously, not only reduced production cost, and saved the space.
4. because new pitch does not mix, reduced the influence of pitch like this in tube, avoided when each start the cleaning of tube has been improved the operating efficiency of regeneration agitator greatly, improved service life tube inwall and stirring vane group.

The specific embodiment:
From Fig. 1 to Fig. 3 as can be seen, a kind of two-layer cylinder asphaltic concrete mixer, comprise base 1, the urceolus 3 of band discharging opening 2, described base 1 is provided with transmission device 4, described urceolus 3 is arranged on the described transmission device 4, and can be with respect to base 1 rotation by the transmission of transmission device 4, on the inwall of described urceolus 3, be provided with paddle slurry group 5, it is characterized in that: the coaxial line of described urceolus 3 is provided with the inner core 7 of an end band discharging vane group 6, also is provided with paddle slurry group 5 on the inwall of described inner core 7; Described base 1 is provided with inner core panel 8 and urceolus panel 9, be set in described inner core 7 and urceolus 3 a end away from discharging opening 2, have charging aperture 10 at described inner core panel 8 and urceolus panel 9, have burning inlet 11 at described inner core panel 8 centers.
Discharge for the flue gas that will be produced in the diesel combustion process, described urceolus panel 9 is provided with air-introduced machine 12, can utilize high-temperature flue gas that the waste and old material in the urceolus 3 is carried out reverse-flow heating simultaneously, further improves the efficiency of heating surface of waste and old material, energy savings.
Constantly add new aggregate and waste and old material to inner core and urceolus respectively from charging aperture at work, stretch into the diesel combustion nozzle to new aggregate heating, drying from the burning inlet simultaneously, temperature is controlled at the 120-150 degree, utilizes the heat radiation of inner core and high-temperature flue gas that the waste and old material in the urceolus is heated.Under the effect of discharging vane group, new aggregate and waste and old material after the heating fully mix, and behind certain hour the aggregate that mixes are discharged from discharging opening, mix together with pitch in the pitch agitator, just can obtain Recycled Asphalt Pavement.
