Description

Laboratory reclaimed asphalt preparation facilities
Technical Field
The utility model relates to a pitch regeneration technical field, concretely relates to laboratory regeneration pitch preparation facilities.
Background
In recent years, with the rapid development of national economy of China and the continuous prosperity of the transportation industry, the road construction is more and more important in the construction of national infrastructure, and the road materials commonly used in highway engineering at present are asphalt mixtures and cement concrete. The asphalt mixture is used as a main material of the road surface layer of the high-grade road in China, and plays a decisive role in the research and development of the road engineering in China. It is estimated that about 12% of asphalt pavement needs to be renovated every year in our country, about 220 million tons of asphalt pavement waste, and this figure will also increase at a rate of 15% every year. The waste materials not only occupy land resources, but also cause damage and pollution to the ecological environment, so that the application of the asphalt pavement regeneration technology provides an effective way for the treatment of the waste materials. The regeneration of asphalt is the reverse process of aging, and a regenerant can be usually added to improve the compatibility of four components of asphalt, dissolve and disperse redundant asphaltene, and improve the penetration and ductility of asphalt so as to recover or approach the original performance.
At present, when asphalt is regenerated in a laboratory, the old asphalt and a regenerant are generally required to be heated, and then manual stirring is carried out, so that the time and the labor are consumed, and the stirring is not uniform. When the regenerant is added, a mode of adding and stirring the regenerant in multiple times is mostly adopted, so that the regenerant needs to be heated for multiple times, and the regenerant is possibly subjected to thermal aging to influence the performance of the regenerant. In addition, the mixing amount of the regenerant cannot be accurately controlled by manual dumping, and great influence is caused on experimental results.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: problem and not enough to exist among the prior art, the utility model provides a mix even, automatic high-efficient and experiment laboratory regeneration pitch preparation facilities that the accuracy is high.
The technical scheme is as follows: the utility model provides a laboratory regeneration pitch preparation facilities, includes base, support and the rabbling mechanism of setting on the support, its characterized in that: the device also comprises a regenerant storage bin and a heating base plate which are fixedly arranged on the base, and a liquid pump, a liquid metering instrument and a stirring mechanism which are arranged on the bracket;

the utility model discloses the technical scheme who further injects does:
preferably, the rotating shaft can be extended and retracted up and down.
Preferably, the stirring blades are three and are uniformly distributed along the circumferential direction of the outer wall of the rotating shaft at 120 degrees.
Preferably, the number of the supports is four, the supports are uniformly distributed along the circumferential direction of the pot body at 90 degrees, six rows of circular spray holes uniformly distributed along the circumferential direction are formed in the spraying device, and the spraying device can be closed and controlled in real time.
Preferably, the two sides of the liquid supply pipeline are provided with heat preservation pipes, and hot air flow which continuously and circularly flows is arranged in the heat preservation pipes.
Has the advantages that: compared with the prior art, the utility model has the advantages of it is following:
1) the device can realize continuous heating and heat preservation of raw materials in the asphalt regeneration process. The heating base plate on the support can heat the old asphalt and the regenerant to be softened into a flowing state, and the hot air continuously and circularly flowing in the heat preservation pipe can prevent the temperature loss in the conveying process of the regenerant, so that the influence of the temperature on the experimental result is reduced to the maximum extent.
2) This device is equipped with drawing liquid pump and liquid measurement appearance, through the speed that adjusts the steerable asphalt recycling agent of drawing liquid pump power and spray, sprays the volume through the steerable asphalt recycling agent of liquid dosage meter, accomplishes regularly and quantitatively to spray, accurate control.
3) But the orifice real time control closure state on this device sprinkler, the area scope that sprays of steerable pitch regenerant, in addition, agitating unit can reciprocate and steerable stirring leaf slew rate, and manual stirring labour saving and time saving compares, and the gained sample is more even.
