Description
Technical field
This utility model relates to heating and the regeneration field of Colophonium waste material, adding of a kind of Colophonium waste material
Heat and generating apparatus again.
Background technology
Relative to cement pavement, bituminous paving possesses that maintenance is efficient and convenient, the good view with periphery of driving condition compares association
The advantages such as tune, increasing highway and town road employ bituminous paving, and bituminous paving already takes up domestic mileages of transport route
More than 95%.
Bituminous paving is along with the increase of the time of use, it may appear that different diseases, causes bituminous paving to start breakage.Damaged
After bituminous paving need the road surface that after milling, making is new again.The annual bituminous concrete milling material (Colophonium waste material) produced
About more than 10,000,000 tons, and along with the increase of bituminous paving quantity, this quantity is also being constantly increasing.
Colophonium waste material contains the Colophonium of 3～5%, abandon these waste materials need place, natural degradation need centuries with
On time, environment is worked the mischief.3～the Colophonium of 5% that additionally Colophonium waste material contains, despite certain aging, but
The Colophonium of this part can realize regeneration, and the rubble contained by Colophonium waste material is also the most valuable building
Material.The most how to realize efficiently, in high quality to Colophonium waste material regenerating, be that the most in the urgent need to address one asks
Topic.
Existing asphalt-regenerating technique has plant-mix recycling and two kinds of techniques of road surface situ regeneration.
After plant-mix recycling refers to heat Colophonium waste material, add the new aggregate of a part and new Colophonium/regenerative agent,
Stir into new reclaimed asphalt mixture.This is to use most methods on Vehicles Collected from Market, and technique is simple, due to Colophonium waste material
The tail gas of heating system need to new aggregate drying system to go burning, to remove Colophonium smog, the most this technique is the most only
Can realize the utilization of the Colophonium waste material of 50%, and equipment volume is excessive, flow process is relatively long, it is impossible to realizes 100% and entirely regenerates,
Promote it is thus desirable to improve.
Road surface situ regeneration technique, refers to utilize far infrared heated asphalt road surface on the spot, then the Colophonium after heating
Raking off in road surface, is stirred after adding new aggregate, new Colophonium/regenerative agent, and making is on road surface the most again.This technique
Maximum problem is to utilize FAR INFRARED HEATING easily to accelerate the aging of bituminous paving, and the degree of depth heated is not enough, Zhi Nengjia
Hot about 40mm, regeneration can only solve asphalt surface course problem, and the disease that middle cutting optimal produces but cannot solve.
Utility model content
Technical problem to be solved in the utility model is the defect overcoming above-mentioned prior art to exist, it is provided that a kind of Colophonium
