Description
Technical field
The present invention relates to a kind of Horizontal type asphalt concrete regenerating machine.
Background technology
Because the country seeks unity of standard with regard to asphalt concrete regeneration equipment and technique neither one, simply reworked material is given
Meet pavement performance requirement.At present, the asphalt concrete regeneration equipment used in the market substantially has two kinds：One kind is continous way,
One kind is batch (-type) (point high-low position).Firstth, continous way is that one section of fixed outer cylinder is provided with outside primary material Drying, inside and outside
Space between cylinder is as the space for drying reworked material, and inner cylinder has welded stirring vane, and in operation, inner cylinder rotating passes through paddle
The reworked material of heating is sent to the outlet of low side by piece, is mixed into primary material in scale hooper, produces finished asphalt concrete.
But there is following drawback：1st, the asphalt concrete quality produced is unstable, it is impossible to adapt to high grade pavement quality requirement；2、
Operation is difficult to grasp, and is not easily cleaned between two after binding material, time and effort consuming during cleaning；3rd, virgin material is being individually produced without reworked material
When, drying barrel radiating is big, causes waste of fuel.Therefore, this continous way regenerating device is given birth to using outer large area except small area
Production it is basic without.Secondth, intermittent regeneration equipment is separately to be additionally arranged a set of independence on the basis of batch (-type) action of forced stirring station
Drying, burner and bypath system.There is high-order, two kinds of low level：First, a high position is that Drying is erected at the high-altitude (title of mixing plant
Above batch box), the reworked material pre-processed is put on by elevator enters Drying, dries the reworked material heated and is put into storage warehouse
In, storage warehouse has scale hooper, by control system according to the valve under the Weight control storage warehouse of setting, makes in storage warehouse
Material add scale hooper, then load weighted material is put into agitated kettle and newly gathered materials, process action of forced stirring is produced together with new pitch
Finished product (ratio is wide).2nd, low level is that reworked material Drying is set on the ground, and the reworked material after heating is mentioned by elevator
The reworked material storage warehouse of eminence, afterwards program it is identical with a high position (low level due to hot material easily bond Lifting machine dipper be not easily cleaned, institute
All to advocate with a high position).Heating technique both it is the same.Specifically：Drying is the inclination angle installation with 3-6 °
On pedestal, equipped with support roller, gear wheel, gear ring and transmission system, burner and bypath system.Expect the high-end entrance from Drying,
Drying cylinder rotation is flowed out by low side, while the flame of burner is also to enter from the high-end center of Drying, unavoidable part is expected
Want and flame contact, cause the ageing of asphalt in some reworked materials and burn, tail gas discharge has blue cigarette, and (blue cigarette environmental protection does not allow straight
Row).In order to solve environmental issue, some enterprises are improved, and flue gas is introduced to the combustion chamber of primary material Drying with pipeline
Second-time burning is carried out, though so solving the environmental issue of fume emission, the problem of aging of partial regeneration material is but difficult to control
System；Separately have, the flue gas for introducing former drying raw meal combustion chamber occupies the space of primary gas turbine liquid-fuel burner flame, corresponding original drying raw meal
The flame of burner must just turn down, so as to influence the yield of primary material.Therefore, in order to solve the two of Recycled Asphalt Pavement
Secondary aging, the environmental issue of fume emission and the production problems for not influenceing primary material production, through on-the-spot investigation and local test, lead to
Cross and study repeatedly, design modification, develop a kind of Horizontal type asphalt concrete regenerating machine.
