Description
Technical field
The invention belongs to highway engineering machine technical field, relate to a kind of for sheet pavement in-situ heat regeneration equipment, specifically a kind of road surface hot recycling hot air circulation leveled heating device.
Background technology
The heat temperature raising mode of the road surface Bituminous concrete surface material of current various sheet pavement in-situ heat regeneration equipment both domestic and external has two kinds, and one is hot blast direct baking ground, and two is naked light direct baking ground.Both modes all existing defects, i.e. bituminous paving surface temperature is too high, and asphalt high-temperature is aging；The mode of heating on naked light direct baking ground then makes bituminous paving surface temperature the highest, and easily catching fire, ageing of asphalt.Now on the basis of hot blast direct baking ground upgrading with diesel fuel burner as thermal source, produce hot blast, and hot blast is contacted by the asphalt that heat exchange is loose with ground uniformly, improve Hot-blast Heating effect, but the asphalt of which regeneration does not still reach the minimum temperature requirement of bituminous pavement paving, and owing to Colophonium is by high-temperature denatured, mixture gradation changes, and causes the pavement quality heavily spread to be difficult to reach requirement.
Summary of the invention
The present invention is directed to the problems referred to above, it is provided that a kind of road surface hot recycling hot air circulation leveled heating device, use this device can effectively realize the uniform heating of asphalt.
According to technical scheme: a kind of road surface hot recycling hot air circulation leveled heating device, it is characterized in that: include the hot blast casing being arranged on vehicle frame, it is fixedly installed combuster, circulating fan on described hot blast casing, it is connected by pipeline between air outlet and the air inlet of combustor of circulating fan, it is provided with conveying plate chain in hot bellows body, circulation upper air duct, combustor lower end air outlet communication loop upper air duct is formed between conveying plate chain upper surface and hot blast tank floor；Being additionally provided with feeding vertical case on described vehicle frame, the discharging opening of feeding vertical case, towards the feed end of conveying plate chain, forms circulated air lower air duct between described conveying plate chain lower surface and ground floor asphalt.
As a further improvement on the present invention, described combustor is fixedly installed diesel fuel burner near circulating fan side.
As a further improvement on the present invention, described frame downward is provided with plate chain and fixes seat, and plate chain is fixed seat two ends and rotated respectively and arrange rotation roller, and conveying plate chain tensioning is arranged on described rotation roller；Plate chain is fixed and is provided with vent on seat, described vent communication loop upper air duct, circulated air lower air duct.
The method have technical effect that: product of the present invention produces hot blast with diesel fuel burner for thermal source, by new, the old asphalt mixture mix homogeneously on ground, it is sequentially sent in the region of relative closure, making new, old asphalt mixture granule contact with hot blast with bigger exchange area, and the asphalt granule of heat exchange is divided into two-layer one on the other by the present invention, heat-transfer effect is more preferably, the thermal efficiency is high, Colophonium is difficult to aging, quick heating, can reach preferable mixture temperature.And whole system is in a forced circulation space comparing closing, old asphalt mixture heats up after burning in produced bitumen flue gas returns to air stove and discharges, and decreases environmental pollution.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is further described.
In Fig. 1, including diesel fuel burner 1, combustor 2, high-temperature flue 3, vehicle frame 4, feeding vertical case 5, conveying plate chain 6, circulated air upper air duct 7, circulated air lower air duct 8, low temperature flue 9, circulating fan 10, vent 11, hot blast casing 12, ground floor asphalt 13 etc..
As shown in Figure 1, the present invention is the hot blast casing 12 including being arranged on vehicle frame 4, combuster 2, circulating fan 10 it is fixedly installed on described hot blast casing 12, it is connected by pipeline between the air outlet of circulating fan 10 and the air inlet of combustor 2, conveying plate chain 6 it is provided with in hot blast casing 12, circulation upper air duct 7, combustor 2 lower end air outlet communication loop upper air duct 7 is formed between conveying plate chain 6 upper surface and hot blast casing 12 bottom surface；Being additionally provided with feeding vertical case 5 on described vehicle frame 4, the discharging opening of feeding vertical case 5, towards the feed end of conveying plate chain 6, forms circulated air lower air duct 8 between described conveying plate chain 6 lower surface and ground floor asphalt 13.
It is fixedly installed diesel fuel burner 1 near circulating fan 10 side on described combustor 2.
Described vehicle frame 4 bottom is provided with plate chain and fixes seat, and plate chain is fixed seat two ends and rotated respectively and arrange rotation roller, and conveying plate chain 6 tensioning is arranged on described rotation roller；Plate chain is fixed and is provided with vent 11 on seat, described vent 11 communication loop upper air duct 7, circulated air lower air duct 8.Forming high-temperature flue 3 at combustor 2 lower air outlet, hot blast casing 12 rear portion is provided with low temperature flue 9, and low temperature flue 9 connects with the air intake of circulating fan 10.
The work process of the present invention is as follows: complete equipment is driven by driven by engine hydraulic system, the Generator storage battery power supply that diesel fuel burner 1 and control system are driven by hydraulic motor, feeding vertical case 5, conveying plate chain 6, circulating fan 10 are by fluid motor-driven, it is achieved stepless time adjustment.
By diesel fuel burner 1 flue gas that burning produces in band burns the combustor 2 of function, hot blast enters high-temperature flue 3, and branch to circulated air upper air duct 7 and circulated air lower air duct 8, heat exchange is carried out with from feeding vertical case 5 new old asphalt mixture out, heated compound one layer is positioned on conveying plate chain 6, and one layer is positioned on construction road surface, and then the hot blast through heat exchange converges entrance low temperature flue 9 by circulating fan 10, final to circulating fan 10, complete hot air circulation.
