Abstract
A heater for thermally regenerating the asphalt pavement by direct radiation heating to repair and maintain the asphalt pavement is composed of an air heating boiler, a circulating blower, a heating box with several rows of spray holes and suspended under said boiler, a lifting mechanism, and several telescopic heating tubes with spray holes and connected between heating box and telescopic mechanism. Its advantages are high heat efficiency and saving fuel.
Description
Technical field
The present invention relates to asphalt pavement repairing and maintenance special equipment.
Background technology
It is to adopt bituminous mixture and provided by bituminous mixing plant that traditional road pavement is repaired maintenance, heats transport vehicle with special insulation and transports.This mode is subjected to time, spatial constraints.Utilize traditional mode to repair the maintenance road surface and have the shortcoming that inefficiency, energy consumption are big, the preparation of construction time is long, exist the shortcoming of construction very flexible also strong simultaneously the bituminous mixing plant dependence.Traditional bituminous mixture mode of heating for directly to pitch heat.Heating quality is poor, and environment is caused severe contamination.Now the flexible pavement to breakage has a kind of in-situ heat regeneration heating means to improve traditional approach, but during its practical operation, the energy of consumption is bigger, and is fair, poor stability.
Summary of the invention
The asphalt surface hot reproduction heater that The present invention be directed to above-mentioned shortcoming and design its objective is that providing a kind of directly heats flexible pavement and simple to operate, energy consumes for a short time, and repairing quality is good, safe asphalt surface hot reproduction part of appliance.
Major technique of the present invention thes contents are as follows.
This asphalt surface hot reproduction heater is characterized in that: circulating fan is positioned at by the hot air boiler, and heating cabinet hangs under the hot air boiler, before elevating mechanism is placed in hot air boiler, the case cover covers on outside the heating cabinet, and flexible heating tube one end connects with heating cabinet, and the other end connects with telescoping mechanism.
The invention has the advantages that:
1, this heating system adopts the concentrated combustion formula, overcome and disperse combustion-type to be difficult for realizing the weakness of control automatically, the flue gas that burning produces adopts the high-temperature blower heating that circulates, can control the temperature of the high-temperature flue gas of burning back generation automatically, satisfying under the condition of construction requirement fuel saving to greatest extent, has higher economical efficiency.
2, because pitch material thermal transmittance is not high, pitch takes place easily rottenly when heating-up temperature is too high, and it is rotten that this heater heating road surface can not make pitch take place, and the temperature raising on chien shih road surface when the shortest, and then keep this temperature, guarantee that bituminous concrete is in maximum heat transfer state.The layout of the heating cabinet of this heater and the spray-hole of flexible heating tube is exactly to arrange the road pavement heating according to such rule.Injection aperture is according to the heating efficiency of heater simultaneously, guarantee that high-temperature flue gas is sprayed onto heated road surface from spray-hole and has certain speed, injection by the high temperature gas flow road pavement further improves the concrete heat transfer rate of drop, makes the thermal transmittance of bituminous concrete reach maximum by the temperature of high-temperature flue gas and the control of jet velocity.Simultaneously, heating cabinet and flexible heating tube are manufactured by special material, can send certain wavelength infrared rays under the effect of high-temperature flue gas, and infrared rays has certain penetration capacity, improve the programming rate of drop rigid pavement bottom, thereby further improve the heat transfer rate on road surface.
3, flexible heating tube can be adjusted the length of stretching out as requested arbitrarily, heat the drop rigid pavement that is fit to different in width, and heater flexible heating tube when transporting and do not add hot work is regained simultaneously, reduces the width of car load, compact conformation is convenient to transportation and transition.
4, heater outer cover incubator cover, high velocity jet is to the high-temperature flue gas on road surface, after heat energy is passed to the pitch material, its temperature descends, but its temperature still also has many heats at 300 ℃ to 400 ℃, and the incubator cover is kept at this part gas in the case cover to suck back through high-temperature blower and is heated to rated temperature, enters next circulation and continues heating drop rigid pavement, high-temperature flue gas is recycling, makes this heater have high thermal efficiency.The incubator cover makes the hull-skin temperature of case cover not be higher than 60 ℃ of safeties that also ensure in the also whole heating system operating process simultaneously.
Description of drawings
Concrete structure of the present invention is provided by the following drawings.
Fig. 1 is the structural representation of asphalt surface hot reproduction heater;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the upward view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described further.
As shown in Figure 1, 2, 3, this asphalt surface hot reproduction heater, it is characterized in that: it is other that circulating fan 1 is positioned at hot air boiler 2, heating cabinet 7 hangs sub-hot air boiler 2 times, before elevating mechanism 3 is placed in hot air boiler 2, case cover 5 covers on outside the heating cabinet 7, and flexible heating tube 6 one ends connect with heating cabinet 7, and the other end connects with telescoping mechanism 4.Heating cabinet 7 is pressed the spray-hole that bituminous concrete conduction of heat rule distributes by number row, can realize the heating function to asphalt concrete pavement.Flexible heating tube 6 every heating tubes are pressed the spray-hole that bituminous concrete conduction of heat rule distributes according to heating location difference of living in by number row, can realize the heating function to asphalt concrete pavement, and adaptation are used to the asphalt concrete pavement heating of different in width.
