Description
Technical field
The present invention is a kind of sheet pavement in-situ heat regeneration bituminous mixture heater that is used for, and is a kind of heater that is used to heat the asphalt-regenerating mixture strip specifically.
Background technology
Usually be that pitch mixed layer to damaged road crust heats with sheet pavement in-situ heat regeneration vehicle in the sheet pavement in-situ heat regeneration equipment construction, make its fusion, it is harrowed pine and is gathered into continuous strip, promote the new bituminous mixture that proper proportion picked up compound, promote and mix by remixer by asphalt-regenerating mixture again, heating mixes, and directly sends into after stirring again in the hopper of paver thereafter; Compacting then paves.At this moment be concentrated into banded heating back asphalt-regenerating mixture (strip) to the middle part, road surface, not having heating and heat-insulating device, is to be exposed to airbornely, and heat in the asphalt-regenerating mixture is loss constantly, the asphalt-regenerating mixture of this moment does not reach the needed construction temperature that paves.If pave, the asphalt-regenerating material interlayer thermal bonding mass ratio that paves is relatively poor, can't satisfy the asphalt pavement construction quality requirement well.
Summary of the invention
Technical problem to be solved by this invention, be to remedy the interlayer thermal bonding temperature that the bituminous mixture that exists in the existing large-scale asphalt surface hot reproduction repairing equipment does not reach regulation, the asphalt-regenerating mixture heat can't be avoided the existing demixing temperature defective of scattering and disappearing, a kind of heated air circulation type bituminous mixture strip heater is provided, before the asphalt-regenerating mixture strip is picked up compound by asphalt-regenerating mixture lifting remixer, heated air circulation type bituminous mixture strip heater is to the strip heat tracing, the requirement of the bituminous mixture construction temperature when solving asphalt surface hot reproduction maintenance paving operation.
Heated air circulation type bituminous mixture strip heater is made of heating mantles, burner, combustion chamber, blast fan; Heating mantles is trapezoidal or the arch trihedral, and two sides respectively are provided with an air-suction channel; The combustion chamber is established at the heating mantles top, the inner UNICOM of combustion chamber and heating mantles; The burner fuel nozzle places in the combustion chamber; The exhaust duct of blast fan connects the combustion chamber, and blast fan has two aspiration channels, and aspiration channel links to each other with the air-suction channel of heating mantles dual-side respectively.
Evenly be laid with some wind inlets on the described air-suction channel, the air draught direction of wind inlet is vertical with the heating mantles cover.
Two bases of described heating mantles are provided with sled.
The utility model, simple in structure, with low cost, be specially adapted to the bituminous mixture strip and be raised the heat tracing of remixer before picking up, the requirement of the bituminous mixture construction temperature in the time of can guaranteeing asphalt surface hot reproduction maintenance paving operation.
Description of drawings:
Fig. 1 heated air circulation type bituminous mixture strip heater structure schematic diagram
Fig. 2 heated air circulation type bituminous mixture strip heater (Figure 1A to) schematic diagram
The specific embodiment:
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, 2, heated air circulation type bituminous mixture strip heater is made of heating mantles 5, burner 2, combustion chamber 3, blast fan 7; Heating mantles is trapezoidal trihedral, and two sides respectively are provided with an air-suction channel 8, evenly is laid with some wind inlets 81 on the described air-suction channel 8, and the air draught direction of wind inlet 81 is vertical with the heating mantles cover.Combustion chamber 3 is located at heat cover top, the mutual UNICOM of opening that combustion chamber and heating mantles inside are offered by the heating mantles top, and this opening is stamped porous heat sink 9; Burner 2 fuel nozzles place in the combustion chamber; The exhaust duct 6 of blast fan connects the combustion chamber, and blast fan has two aspiration channels 4, and aspiration channel 4 links to each other with the air-suction channel 8 of heating mantles dual-side respectively.
On heating mantles 5, rotate by motor 1 belt driven blower 7, air-breathing from the aspiration channel 4 of both sides, supply gas for combustion chamber 3 by exhaust duct 6.While burner 2 (for the existing product that are purchased) ejects vaporific diesel oil and burns in combustion chamber 3, heat is by porous heat sink 9, be delivered to heating mantles 5 inside, its internal temperature is raise fast, reach pitch can access heat tracing in heating mantles 5 purpose.
Being connected of 5 liang of outer ledge two air-suction channels 8 of aspiration channel 4 and heating mantles, row's wind inlet 81 has evenly gathered on the air-suction channel.After heated air circulation type strip heater work a period of time, heating mantles 5 internal temperatures raise, and blast fan 7 absorbs hot air by the wind inlet that gathers on two air-suction channels 8, make combustion chamber 3 interior diesel combustions more cmpletely.The air door effect that the getter action of the densely covered wind inlet 81 on the heating mantles 5 both sides air-suction channels 8 simultaneously produces makes that temperature losses reduce in the heating mantles 5, keeps relative constant thereby reach temperature in the heating mantles 5, and is more abundant to the heating of bituminous mixture.
Heated air circulation type bituminous mixture strip heater in order to reduce the resistance to ground, slides smoothly in the process of pulling by chain, in vertical both sides, the base of heating mantles 5 sled 10 is installed.Heated air circulation type strip heater is pulled by chain by sheet pavement in-situ heat regeneration vehicle, advances as linear slide along the continuous strip direction of bituminous mixture, and strip is carried out continuous heating and insulation.
