In this embodiment, the asphalt recovery flow is as follows:
S1, recycling and putting waste asphalt on a highway area to be maintained into an asphalt recycling bin 4, flushing and screening the asphalt recycling bin 4 by using clear water, and removing dust and other visible impurities on the surface of the waste asphalt;
S2, placing the waste asphalt cleaned in the step S1 at a temperature of 100-120 ℃ for microwave heating for 100-130min, decomposing the waste asphalt into small particles,
S3, when the temperature of the waste asphalt treated in the step S2 is reduced to 60 ℃, injecting a trichloroethylene solution into the waste asphalt to submerge the waste asphalt, and performing centrifugal separation and filtration to separate asphalt extract from asphalt aggregate, wherein the recycled asphalt aggregate is directly used for highway maintenance, so that the consumption of asphalt aggregate raw materials is reduced,
S4, heating the asphalt extract produced in the step S3 in an oil bath, controlling the heating temperature to be 100-110 ℃, and evaporating the trichloroethylene by utilizing the difference of the boiling points of asphalt and the trichloroethylene to realize separation of the asphalt and the trichloroethylene;
s5, condensing the trichloroethylene generated in the step S4 to 60 ℃ for recycling and re-injecting the trichloroethylene into the solution formed in the step S3, so that the recycling of the trichloroethylene is realized, the waste of the trichloroethylene is reduced, and the diffusion of the trichloroethylene steam into the air is avoided;
S6, heating the asphalt obtained in the step S4 to more than 150 ℃ to form high-temperature liquid asphalt, pumping the high-temperature liquid asphalt into a transition cavity 902 by an asphalt pump, then driving a push plate 21 to move up and down under the driving of an air cylinder 23, pushing the asphalt into a blanking pipe 19 from the transition cavity 902, and conveying the asphalt into a foaming cavity 901 along with the downward movement of the push plate 21, wherein the up and down reciprocating movement of the push plate 21 not only plays a role in switching asphalt supply into the foaming cavity 901, but also plays a role in mechanically cleaning residual asphalt,
S7, in the process of the step S6, the water pump sprays cold water from the first annular groove 9001 and the water nozzle 903 onto the hot asphalt in the foaming cavity 901, the cold water exchanges energy with the hot asphalt, the temperature of water drops is increased, and meanwhile, the temperature of surrounding asphalt is reduced;
S8, the air pump sprays high-pressure gas generated by compression into the foaming cavity 901 from the second annular groove 902 and the air nozzle 904 to form a high-pressure environment in the foaming cavity 901, cold water is subjected to energy exchange with hot asphalt to heat so as to generate steam which expands rapidly, steam bubbles are pressed into continuous phases of asphalt under the pressure effect generated by the high-pressure gas so as to form asphalt foam, foaming treatment of recycled asphalt is completed, water flow generated by pumping water by the water pump and air flow generated by pumping air by the air pump are not only used for foaming the asphalt, but also impact force generated by pumping air is beneficial to blowing the asphalt into the foaming cavity 901, consumption of asphalt raw materials is reduced through recycling after foaming treatment, highway maintenance cost is reduced, and highway maintenance efficiency is ensured due to the fact that asphalt raw materials are additionally provided.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
