Abstract
The utility model relates to a hot blast heating device used in repairing bituminous pavement, comprising a hood-type heating cavity, wherein, the upper end of the hood-type heating cavity is provided with a blower device; the air outlet of the blower device is communicated with the intracavity of the heating cavity; the fan blades of the blower device are arranged inside an air inlet cavity; the air inlet cavity is communicated with an air inlet; the air inlet is communicated with a hot blast source. During use, a heat source enters into the air inlet cavity through the air inlet of the blower device, and then fed-in hot blast is evenly dispersed inside the heating cavity through the fan blades to heat a to-be-repaired road surface; meanwhile, surplus hot blast returns to the air inlet cavity through a return air channel, and is mixed with newly fed-in hot blast to heat the to-be-repaired road surface once again; therefore, the utility model reaches the goals of rapid heat transfer and energy saving.
Description
Technical field
The utility model relates to a kind of asphalt pavement repairing hot air heating apparatus that is applicable to the construction of novel asphalt pavement engineering.
Background technology
For the repairing of flexible pavement, the method that adopts is at present: need carry out batch mixing in fixing stock ground, the benefit road material that mixes is transported to the job site with special insulation heating transport vehicle, this kind mode is subjected to the restriction in time and space.At present, occur some on the market and can be directly used in the road surface in-situ heat regeneration heater of repairing the road surface, as refractory brick heater, infrared element etc., the major defect of these heaters is: volume is very big, the manufacturing cost height, relatively heavier in pavement construction, use very inconvenient, heat energy utilization is also insufficient, and utilization rate is very low.The most important thing is the existing small size repairing that is unfavorable for the road surface about asphalt pavement repairing with device, great majority all are to concentrate repairing with large-scale pavement patching device, method for repairing and mending commonly used is just to repair when overstocking the bad swag on the road surface to certain quantity, so not only the operation to vehicle has caused very big inconvenience, and having caused the significant waste of manpower and material resources, operating efficiency is very low.
The utility model content
At the problems referred to above, the purpose of this utility model is to provide a kind of thermal efficiency height, and environmental protection and energy saving are specially adapted to the asphalt pavement repairing hot air heating apparatus that small size is repaired.
To achieve these goals, the technical solution of the utility model is to have adopted a kind of asphalt pavement repairing hot air heating apparatus, comprise button bell-type heating chamber, upper end at button bell-type heating chamber is provided with a blower fan apparatus, the air outlet of blower fan apparatus and the intracavity inter-connection of heating chamber, the fan blade of blower fan apparatus is arranged in the air-inlet cavity, and air-inlet cavity is communicated with air intake, and air intake is used to be communicated with hot air source.
Be provided with a return air channel in the described button bell-type heating cavity, the lower end of return air channel is communicated with the inner chamber of heating chamber, and the upper end is connected with the air-inlet cavity of blower fan apparatus.
Described return air channel outer wall is provided with one deck thermal insulation layer.
Described thermal insulation layer is made by ceramic fibre material.
Above blower fan apparatus, a warning lamp can also be set.
Owing to adopt structure of the present utility model, upper end at button bell-type heating chamber is provided with a blower fan apparatus, the air outlet of blower fan apparatus and the intracavity inter-connection of heating chamber, and the fan blade of blower fan apparatus is arranged in the air-inlet cavity, air-inlet cavity is communicated with air intake, and air intake is used to be communicated with hot air source.Thermal source enters air-inlet cavity by the air intake of blower fan apparatus, evenly disperse to advance the hot blast that enters in the heating cavity by fan blade then, be used for heating road surface to be mended, the surplus hot blast that looses comes back to air-inlet cavity by return air channel, and and heat road surface to be mended once more after the new hot blast mixing that feeds, to reach flash heat transfer, the purpose of energy conservation.Device of the present utility model has the following advantages: heat waste is few, and firing rate is fast, and environment-friendly high-efficiency through burning again, can make full use of it to the waste gas that produced, has saved the energy, has reduced pollution again; Improve the regeneration quality, make waste asphalt mixture can be able to regeneration, reduced cost; Weight of equipment is light, simple in structure, and is easy for operation, is convenient to pavement construction and uses, and improved the speed of repairing the roads, and reduced working strength of workers; Can set hot blast temperature according to the different pitches road surface, temperature can be controlled automatically, and not only firing rate is fast, and heating surface is even, and pitch is not aging; A tractor serves several purposes when running into bituminous mixture need add heat construction in pavement construction, can also heat convenient and swift, saving of work and time on the spot; At construction operation faces such as rut, hole groove, frost boilings, it can make up by multimachine, all right layering heating, construction in layer.The utlity model has favorable social and economic worth, be easy to apply.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, blue or green pavement patching hot air heating apparatus of the present utility model, comprise button bell-type heating chamber 1, upper end at button bell-type heating chamber 1 is provided with a blower fan apparatus 2, the air outlet 3 of blower fan apparatus 2 and the intracavity inter-connection of heating chamber, the fan blade 4 of blower fan apparatus 2 is arranged in the air-inlet cavity 5, and air-inlet cavity 5 is communicated with air intake 6, and air intake 6 is used to be communicated with hot air source.Be provided with a return air channel 7 in button bell-type heating cavity, the lower end of return air channel 7 is communicated with the inner chamber of heating chamber 1, and the upper end is connected with the air-inlet cavity 5 of blower fan apparatus.Be provided with one deck thermal insulation layer 8 at return air channel 7 outer walls, the thermal insulation layer of present embodiment is made by ceramic fibre material.In addition, a warning lamp 9 can also be set above blower fan apparatus, when work, be used to remind the pedestrian to note.
During work, under the driving of blower fan apparatus 2, utilize the liquefied gas flame gun that thermal source is provided, thermal source enters from air intake 6, adds hot air simultaneously, under the transmission of fan blade 4 hot gas is disperseed, and acts in the heating chamber 1.In heating chamber 1 needed heating position is heated, the residual heat air constantly carries out recycling use by return air channel 7 in the heating process, thereby realizes the thermal regeneration of bituminous mixture.
It should be noted last that: above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the utility model, and do not break away from any modification or partial replacement of spirit and scope of the present utility model, as change to the heating cavity profile, as changing the heating cavity bottom into square or circle, it all should be encompassed in the middle of the claim scope of the present utility model.
