Put into mix stove with waste asphalt and heat mix, waste asphalt is made to be modified, then by new pitch, it is new gather materials etc. put into mix
Mix is heated in stove ultimately produces regeneration asphalt.The process needs successively input regenerative agent, new pitch and newly gathers materials, operation step
It is rapid more, it is more troublesome, and existing regenerative agent is all liquid, is mostly used barreled, and be that regenerative agent is manually poured over mix mostly
In stove, it is difficult to control its dosage, regenerative agent is contained it is also necessary to take into account that the problems such as anti-leak, anticollision using plastic barrel, is not easy to
Transport, so the structure of existing regenerative agent has much room for improvement.Studies in China person is based on composition regulation theory, united Lagrangian- Eulerian method simultaneously
With rubber basic theory develop it is a variety of it is hot in-plant reclaimed use regenerative agents, but entity project using effect is bad mostly, mainly due to
Domestic regenerative agent deficient in stability and high efficiency, endurance quality is insufficient, and waste asphalt mixture mixture proportion is less than 35%, no
It is not high to will result only in waste asphalt mixture comprehensive utilization ratio, also results in reclaimed asphalt mixture water stabilizing and low temperature is anti-
Poor performance is split, still has prodigious gap compared to foreign countries.In conclusion existing regenerative agent all exists centainly in structure and formula
Defect, urgent need it is made improvements.
Invention content
The purpose of the present invention is to provide a kind of structures of warm mix regenerative agent, and to solve, regenerative agent is not readily transportable, uses
When dosage not easy to control the problem of.
In order to achieve the above object, base case of the invention is:A kind of structure of warm mix regenerative agent is in capsule structure,
Including capsule shells and regenerative agent, the regenerative agent is described mainly including used oil, graphene, lightweight oil and devulcanized rubber powder
Capsule shells include shell cap and the matched shell of shell cap and the encapsulation circle for capsul cap and housing junction;The shell
The end being open on cap is equipped with the insertion groove being inserted into for shell, and insertion groove is interference fitted with shell, and runner, stream are equipped in insertion groove
Road on insertion groove far from shell one end and there are distance, the runner and shells between the one end of insertion groove far from shell
The inside of cap is connected to, and is additionally provided with perfusing hole on the shell cap, perfusing hole is connected to insertion groove;Close to the one of shell cap on the shell
End is equipped with drainage trough, and drainage trough is connected to insertion groove and positioned at the lower section of perfusing hole;The material and shell cap and shell of the encapsulation circle
Body is identical.
The operation principle and advantageous effect of this base case are:
1. the warm mix regenerative agent in this programme includes capsule shells and its internal liquid regenerative agent.When making, first by shell
Be inserted into the insertion groove of shell cap, and so that perfusing hole, drainage trough, insertion groove and runner is sequentially communicated with formed one for warm mix again
Raw agent by space, warm mix regenerative agent is poured into from perfusing hole then, shell is completely inserted into insertion groove after the completion of perfusion
In, shell will block runner, and warm mix regenerative agent is just blocked in the cavity that is formed between shell cap and shell, meanwhile,
Drainage trough is staggered with perfusing hole, and perfusing hole is also blocked, and improves the leakproofness of capsule shells.Finally encapsulation circle is melted to again
80 DEG C -90 DEG C are packaged the junction of shell and shell cap.Shell cap, shell and encapsulation circle are all used undulation degree in this programme
Material, polyene material and devulcanized rubber powder are made, and the melt temperature of three is between 80 DEG C -120 DEG C, the temperature of the range and drip
Mix temperature close when blueness regeneration, so after being put into mixing equipment, shell cap, shell and encapsulation circle can melt,
Make warm mix regenerative agent and waste asphalt mix.Warm mix regenerative agent is generally all stored in plastic barrel in the prior art, when use
It is by manually toppling over, so being difficult to control its dosage.In the present solution, after shell cap and shell produce, cavity body between the two
Product determines that the quality for the warm mix regenerative agent that can be stored also determines, so need to only put into corresponding number when use, is easy to control
The dosage of warm mix regenerative agent processed.
2. fibrous material and polyene material are remarkably improved the flexibility of reclaimed asphalt mixture and glutinous toughness, regeneration is improved
Water stabilizing, crack resistance at low-temperature and the anti-fatigue performance of asphalt, so the two, which can regenerate pitch, plays rush
Into effect, so shell cap, shell and encapsulation circle be melted in mixing equipment after, it is unfavorable to be generated to regenerating waste asphalt
It influences, the flexibility of regeneration asphalt and glutinous toughness can be improved instead.
3. it needs to be heated when regenerating waste asphalt, and repeatedly high-temperature heating can reduce it for pitch
Performance, and the warm mix regenerative agent in this programme can play the role of reducing waste asphalt mixture mix temperature, avoid high temperature
Heating has an impact asphalt performance.
4. regenerative agent is liquid, so being not easy to contain using common capsule, it is not easy to fill capsule, and these capsules
Pitch can also be regenerated and be had an adverse effect.If capsule is not poured completely, after being put into mixing equipment, in capsule
Air may remain in mixing equipment, make in regeneration asphalt that there are a large amount of bubbles, influence the quality of regeneration asphalt.And this
In scheme, can first be plugged into shell cap and shell makes the two form a cavity that can accommodate warm mix regenerative agent together, then
The perfusion of warm mix regenerative agent is entered by perfusing hole, so this programme can fill capsule shells, there is no air, avoid this
