Asphalt pavement material recycling device and asphalt pavement material recycling method
The invention relates to an asphalt pavement material recycling device and an asphalt pavement material recycling method. The asphalt pavement material recycling device is characterized by comprising a solvent storage tank, wherein the inlet of the solvent storage tank is connected with a condenser by a pipeline, the outlet of the solvent storage tank is connected with the inlet of a solvent tank by a pipeline, the outlet of the solvent tank is connected with the inlet of a solvent pump by a pipeline, the outlet of the solvent pump is connected with the inlets of two washing chambers and a flushing device arranged in a high-speed centrifugal machine by three parallel-connected pipelines respectively, the outlet pipelines of two washing chambers are connected with the inlet of the high-speed centrifugal machine, the outlet of the high-speed centrifugal machine is connected with the inlet of a solvent evaporating pot by a pipeline, the outlet of the solvent evaporating pot is connected with one inlet of a blending tank by a pipeline, the other outlet of the solvent evaporating pot and pipelines of steam outlets at the tops of the two washing chambers are converged by pipelines so as to be connected with the condenser, and the other inlet of the blending tank is connected with a fresh asphalt storage tank by a pipeline. According to the asphalt pavement material recycling device and the asphalt pavement material recycling method, aggregates and old asphalts in the old asphalt mixture can be screened and recycled, and besides, a secondary flushing device is arranged, so that the mixture can be effectively separated and filtered.
