An activated carbon layer is laid at the bottom of the water storage chamber 84, and the activated carbon layer 85 absorbs impurities and pigments in the water, so that the filtered water becomes clearer. The water storage chamber 84 is connected to the water pump 81 through a water pipe.

The implementation principle of the asphalt concrete paver of the embodiment of the application is as follows: when asphalt is loaded, the scraper 5 is located at the side of the hopper 2 away from the feeding pipe 3, and the top of the turnover plate 52 is separated from the frame 51 and turned over to the ground side, thereby facilitating the entry of asphalt into the hopper 2 through the frame 51. During laying of the bitumen, the cover plate 34 is lowered to clear the feeder duct 3. The bitumen enters the spiral distributor through the feeding pipe 3. And finally, after the paving is finished, the electric cylinder is started, the scraping plate 5 moves towards one side of the feeding pipeline 3, and the scraping plate 5 scrapes the asphalt remained on the inner wall of the hopper 2. At the same time, the electric cylinder opens the movable plate 32 from the blanking opening 31 through the transmission member 7. With the operation of the water pump 81, clean water is sprayed onto the scraper 5 from the spray header 42 to wash off asphalt on the scraper 5, and water mixed with asphalt enters the recovery tank 8 through the feeding pipeline 3 and the blanking port 31 in sequence. The pitch at this time is solidified by being cooled by water, and the pitch is not easily stored in the solids collection chamber 83 by passing through the screen 82. And the filtered water permeated into the water storage chamber 84 can be pumped out again by the water pump 81 to wash the scraper 5. The using amount of water resources in the whole process is small, and the effects of high efficiency and energy saving are achieved.
