Description
Technical field
The utility model relates to a kind of road building machinery, relates in particular to a kind of pitch reclamation of old material device.
Background technology
Road building machinery is reused for road surfacing after generally the old material of pitch being regenerated with after virgin material mixes when building road surface or maintenance of surface, be that environmental protection reduces cost again like this.Existing pitch reclamation of old material device can be divided into two kinds by mode of heating: a kind of is long following current mode of heating continuously, and another kind of is the short The intermittent heating of gathering materials.Wherein, adopt the gather materials pitch reclamation of old material device of intermittently heating of short tube to generally comprise frame and be located at old material lifting appliance, heater, old feed roller, mixing plant and exhaust plant on the frame, old material lifting appliance feed opening is connected with old feed roller feeding mouth, the exhaust opening of heater is located at old feed roller feeding mouth the same side and is used for providing regeneration to use hot air to old feed roller, and the discharging opening of old feed roller is connected with mixing plant and exhaust plant respectively.The mode that this kind mode of heating adopts high-temperature gas to enter and discharge from the other end from an end of old feed roller, thereby high-temperature gas is heated to the old material of pitch formed material curtain in the process of shedding, this just causes high-temperature gas to the old material heating of the pitch that carries out parabolic motion better, and it is then very little that the old material of the pitch under other state is added heat.Because the ratio of the old material formation of pitch parabolic motion is less relatively in the unit interval, only about 15%, therefore, make the heating-up temperature of the old material of pitch reach production requirement, just must prolong the time of staying of the old material of pitch in old feed roller or the temperature of raising regenerated heat air, obviously, the former can cause device structure huge, the latter can make the aging serious and energy consumption of reworked material pitch increase, thereby all is uneconomic.
Summary of the invention
The purpose of this utility model provides the pitch reclamation of old material device of a kind of compact conformation, favorable regeneration effect.
The technical scheme that the utility model adopted: a kind of pitch reclamation of old material device, it comprises support and is located at old material lifting appliance, heater, old feed roller, mixing plant and exhaust plant on the support, described heater comprises heating furnace and is located at air inlet pipe and stack on the heating furnace, described stack end is located in the old feed roller and its sidewall is provided with some air vents, and described heater also is provided with ventilator.
Above-mentioned pitch reclamation of old material device is provided with backwind tube between described heating furnace and the old feed roller.
Above-mentioned pitch reclamation of old material device, described air inlet pipe end is located in the old feed roller.
Above-mentioned pitch reclamation of old material device also is provided with the mineral aggregate drying unit on the described support, described mineral aggregate drying unit is provided with drying roller, is provided with induced duct between described drying roller and the old feed roller, and induced duct is provided with air-introduced machine.
The beneficial effects of the utility model are: the air vent that utilizes the stack end, make high-temperature gas carry out interchange of heat with mode of jet and the old material of pitch, the old material of bound bitumen becomes loose under the inverting action of the inboard blade of old feed roller, thereby improve the interchange of heat coefficient of heat transfer, and each device configuration rationally, compact conformation.Further improving is the hot air in the old feed roller to be drawn back heating furnace by backwind tube heat up, send old feed roller again back to, this measure helps reducing the heating furnace energy consumption, the old material of pitch is regenerated under suitable regenerated heat air heat, reduce the degree of aging of regeneration asphalt greatly, further improving is to utilize the tail gas of virgin material drying roller to add the old material of heated bitumen, saves cost, improves the thermal efficiency.

The specific embodiment
With reference to figure 1, Fig. 2, Fig. 3, embodiment discloses a kind of pitch reclamation of old material device, and it comprises support 1 and is located at old material lifting appliance 2, heater 3, old feed roller 4, mixing plant 5 and exhaust plant 6 on the support 1.Wherein:
Described old material lifting appliance 2 comprises hopper 21, guide rail 22, carries material motor 23, the described hopper 21 old material of pitch of when guide rail slides into low level 22 times, packing into, under the traction of carrying material motor 23, turn back to a high position again then, at this moment, the discharging opening of hopper 21 is positioned at old feed roller 4 feeding mouths top, open the discharging opening of hopper 21, then the old material of pitch enters old feed roller 4 and regenerates.
Described heater 3 comprises heating furnace 31 and is located at air inlet pipe 32 and stack 33 on the hot stove 31 of frame, described air inlet pipe 32 other ends are connected with the stirring chamber of old feed roller 4, stack 33 other ends (being defined as stack tail end 7 here) are located in the stirring chamber of old feed roller 4, and this stack tail end 7 is provided with some air vents 71 for hollow structure and its sidewall, stack 33 is provided with ventilator 331 and is used for the hot air that heating furnace 31 produces is sent in the stirring chamber of old feed roller 4, perhaps described ventilator 331 also can be located on the air inlet pipe 32, and its effect is the same.Heater 3 described here can not draw hot blast from old feed roller 4 and advance living reheating, but air inlet pipe 32 directly is communicated with atmosphere, perhaps heater 3 is provided with two air inlet pipe simultaneously, and one of them air inlet pipe is communicated with atmosphere, another air inlet pipe be communicated with old feed roller 4.
Described old feed roller 4 is consistent with known mineral aggregate drying roller, it is the drum type structure that a two ends hollow and axial are provided with opening, thereby this old feed roller 4 drives by the drive motors 41 of being located at its below and axially rotates along it, because old feed roller 4 inside walls are provided with the stirring blade, the old material of pitch that enters old feed roller 4 from hopper 21 is constantly done and is shed action and become loose like this.
Described mixing plant 5 feeding mouths are connected with the discharging opening of old feed roller 4, and mixing plant 5 also is provided with other material such as feeding mouths such as breeze, pitch, and mixing plant 5 belows are provided with discharging opening, promptly can be used for road surfacing through the finished product material after stirring.
