Abstract
The invention belongs to the technical field of road engineering machines, relates to a bituminous pavement in-place hot recycling device, and particularly relates to a hot-wind circulating and layered heating device for pavement hot recycling. The heating device comprises a hot-wind box on a vehicle frame. A combusting chamber and a circulating fan are fixed on the hot-wind box. The wind outlet of the circulating fan and the wind inlet of the combusting chamber are connected by a pipe. A conveying board chain is disposed in the hot-wind box. An upper circulation wind channel is formed between the upper surface of the conveying board chain and the bottom surface of the hot-wind box. The wind outlet at the lower end of the combusting chamber is communicated with the upper circulation wind channel. A vertical feeding box is also disposed on the vehicle frame. The material discharging port of the vertical feeding box faces towards the feeding end of the conveying board chain. A lower circulation wind channel is formed between the lower surface of the conveying board chain and the ground layer that is a bituminous mixture. Even heating of the bituminous mixture can be effectively achieved by the heating device.
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.These two kinds of modes all existing defects, namely flexible pavement surface temperature is too high, and asphalt high-temperature is aging; The mode of heating on naked light direct baking ground then makes flexible pavement surface temperature too high, and easy catching fire, ageing of asphalt.What upgrade on the basis on hot blast direct baking ground now take diesel fuel burner as thermal source, produce hot blast, and hot blast is contacted by the bituminous mixture that interchange of heat and ground are loose uniformly, improve Hot-blast Heating effect, but the bituminous mixture of which regeneration does not still reach the minimum temperature requirement of bituminous pavement paving, and because pitch 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, a kind of road surface hot recycling hot air circulation leveled heating device is provided, adopts this device effectively can realize the homogeneous heating of bituminous mixture.
According to technical scheme of the present invention: a kind of road surface hot recycling hot air circulation leveled heating device, it is characterized in that: comprise the hot blast casing be arranged on vehicle frame, described hot blast casing is fixedly installed combuster, circulating fan, be connected by pipeline between the air outlet of circulating fan and the air intake of combustion chamber, conveying plate chain is provided with in hot blast casing, circulation upper air duct is formed, lower end, combustion chamber air outlet communication loop upper air duct between conveying plate chain upper surface and hot blast tank floor; Described vehicle frame is also provided with feeding vertical case, and 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 soffit and ground floor bituminous mixture.
As a further improvement on the present invention, described combustion chamber 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 holder, and plate chain holder two ends are rotated respectively and arranged live-rollers, and conveying plate chain tensioning is arranged on described live-rollers; Plate chain holder is provided with ventilation opening, described ventilation opening communication loop upper air duct, circulation lower air duct.
Technique effect of the present invention is: product of the present invention is that thermal source produces hot blast with diesel fuel burner, new, the old asphalt mixture on ground are mixed, send into successively in the region of relative closure, new, old asphalt mixture particle is contacted with hot blast with larger exchange area, and the bituminous mixture particle of heat exchange is divided into two-layer one on the other by the present invention, heat-transfer effect is better, the thermal efficiency is high, pitch is not easily aging, quick heating, can reach desirable mixture temperature.And whole system is in a forced circulation space relatively closed, old asphalt mixture heats up the bitumen flue gas that produces get back to burn in hot-blast stove after discharge, decrease environment pollution.
