In the maintenance of new asphalt road surface or old asphalt pavement, on a ground asphalt is prepared in advance at present, with carrier loader asphalt is transported to the job site then, asphalt is in transportation process, particularly winter or,, all adopt conduction oil or flame heating equipment in order to keep the temperature of asphalt in temperature lower season, adopt this two kinds of equipment, complex structure, technical difficulty is big, and is very dangerous, and want consume fuel, improved cost of production.
Summary of the invention
Technical problem to be solved in the utility model and solve the technological scheme that its technical problem adopts and be: in mixing hopper or railway carriage, be provided with heat exchanger, on the exhaust duct of motor car engine, establish the conversion valve or the throw over switch that link with outlet pipe and heat exchanger.
Heat exchanger of the present utility model is: a side of heating pipe is provided with the rear gas chamber, other side that link with heating pipe and outlet pipe and is provided with the preceding air chamber that links with heating pipe in mixing hopper, and preceding air chamber links by pipeline and the conversion valve or the throw over switch that are arranged on the automobile engine exhaust pipe road.
Heat exchanger of the present utility model also can be: be coiled in the S shape heating pipe of mixture chamber interior wall, an end and the pipeline of S shape heating pipe links, another short and outlet pipe links.
Heat exchanger of the present utility model can also be: the interlayer casing along the mixture chamber interior wall, the air intake and the pipeline of interlayer casing links, air outlet and outlet pipe link.
The utility model is compared with the heating plant of existing asphalt in transportation process, and the tail gas that has adopted motor car engine to discharge heats.It has advantages such as reasonable in design, simple in structure, esy to use, safe and reliable, energy saving, cost of production be low, can promote the use of on the asphalt transport vehicle.
Description of drawings
Fig. 1 is an embodiment's of the utility model a structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but the utility model is not limited to these embodiments.
Embodiment 1
In Fig. 1, it is to be connected by flexible pipe 1, conversion valve 2, pipeline 3, silencing apparatus 4, temperature detecting head 5, preceding air chamber 6, heating pipe 7, mixing hopper 8, rear gas chamber 9, outlet pipe 10 to constitute that the automobile engine tail gas of present embodiment adds the hot asphalt mixture device, wherein, preceding air chamber 6, heating pipe 7, rear gas chamber 9, outlet pipe 10 connect the heat exchanger that constitutes present embodiment.
Conversion valve 2 is installed on the exhaust duct of motor car engine, and the exhaust duct of conversion valve 2 and motor car engine and the silencing apparatus 4 that is installed on the exhaust duct of motor car engine link, and conversion valve 2 also can adopt throw over switch.Flexible pipe 1 is installed on conversion valve 2, flexible pipe 1 will link by the indoor operating handle of pull bar or cable wire and car steering, in mixing hopper 8 heat exchanger is installed, the heat exchanger of present embodiment is made of preceding air chamber 6, heating pipe 7, rear gas chamber 9, outlet pipe 10 connections.Air chamber 6 before preceding Side in mixing hopper 8 is equipped with, back Side is equipped with rear gas chamber 9, Side before preceding air chamber 6 is installed in and adds in the heat mixture case 8, rear gas chamber 9 is installed in and adds rear side in the heat mixture case 8, between preceding air chamber 6 and rear gas chamber 9, heating pipe 7 is installed, heating pipe 7 links with preceding air chamber 6 and rear gas chamber 9, preceding air chamber 6 adds the asphalt of forward part in the heat mixture case 8, rear gas chamber 9 adds the asphalt of rear section in the heat mixture case 8, heating pipe 7 adds the asphalt of intermediate portion in the heat mixture case 8, on the preceding air chamber 6 temperature detecting head 5 is installed, temperature detecting head 5 is used to measure the temperature transition of mixing asphalt in the hopper 8 and becomes electrical signal to output to indoor thermometer of car steering or temperature display, outlet pipe 10 is installed in rear gas chamber 9, outlet pipe 10 links with preceding air chamber 6 and rear gas chamber 9, and preceding air chamber 6 links by pipeline 3 and conversion valve 2.Mixing the control of the asphalt temperature in the hopper 8, is with the aperture of regulating conversion valve 2, and the motor car engine discharge tail gas amount that regulating flows through mixes heat exchanger in the hopper 8 realizes.The temperature of the asphalt in mixing hopper 8 is hanged down in the time of need heating the asphalt in the mixing hopper 8, the driver turns conversion valve 2, exhaust duct and preceding air chamber 6, rear gas chamber 9, the outlet pipe 10 of motor car engine are linked, the motor car engine discharge tail gas can enter preceding air chamber 6, the rear gas chamber 9 of mixing heat exchanger in the hopper 8, discharges from outlet pipe 10.The temperature of the asphalt in mixing hopper 8 is higher not to be needed when mixing asphalt in the hopper 8 and heat, the driver turns conversion valve 2, the exhaust duct and the silencing apparatus 4 of motor car engine are linked, and the motor car engine discharge tail gas can be discharged from silencing apparatus 4 through conversion valve 2.Because the utility model has adopted the heater of this structure, the asphalt that mixes in the hopper 8 is heated, simplified heating plant greatly, saved the energy, reduced cost of production.
Embodiment 2
