[0002] Asphalt concrete is a composite material commonly used in pavements, parking lots, airports, and the core of dams. Asphalt mixtures have been used in pavement construction since the early 20th century. Asphalt concrete is an asphalt mixture that meets technical standards and is made up of a suitable proportion of coarse aggregate, fine aggregate and filler, and is mixed with an asphalt binder to form a mineral aggregate that meets the specified grade.

[0003] In order to accurately calculate the passing rate of 0.075mm sieve holes in fine aggregate, water washing is performed during the screening test. Fine aggregate is often placed in a sieve bucket and watered, and then the aggregate is allowed to drain naturally. Because the aggregate is thickly piled, the following problems may occur: first, the water flow can easily impact the aggregate near the center of the sieve bucket, resulting in poor cleaning effect; second, the air circulation between the aggregates in the center of the sieve bucket is poor, and the aggregate drying process is very slow, affecting subsequent work.

[0009] A further technical solution is that nozzles are installed at the outer ends of the water outlet and the connecting pipe.

[0010] A further technical solution is: a heating element is arranged inside the inner tube.

[0011] A further technical solution is: the heating element is an electric heating wire or a heat conducting tube.

[0012] A further technical solution is: the flip mechanism includes a load-bearing plate, a support and a telescopic rod, the support is installed at one end of the load-bearing plate and its top is hinged to the bottom plate, and the other end of the load-bearing plate and the bottom plate are respectively hinged to the two ends of the telescopic rod.

[0031] Based on the above embodiments, this embodiment Figure 2 and Figure 3 As shown, the washing and blowing integrated pipe 2 includes an outer pipe 7, a middle pipe 8, an inner pipe 9 and a connecting pipe 10. The outer pipe 7, the middle pipe 8 and the inner pipe 9 are coaxially arranged from the outside to the inside and form a water cavity 11 located in the outer layer and an air cavity 12 located in the inner layer. The upper ends of the water cavity 11 and the air cavity 12 are sealed and the lower ends are respectively connected to the water inlet pipe 19 and the air inlet pipe 20. A plurality of connecting pipes 10 are evenly distributed along the ring and installed on the outer pipe 7 and the middle pipe 8.

[0033] Embodiment three:

[0034] Based on the above embodiments, this embodiment Figure 2 As shown, a heating element 15 is arranged in the inner tube 9. The heating element 14 is an electric heating wire or a heat conducting tube.

[0035] The heat source is provided to the heat pipe by an external power supply and an electric heating wire, or a heat source (which may be a boiler such as heat-conducting oil, hot water or steam), so as to heat the air in the air cavity 12 and improve the drying speed.

[0036] Embodiment 4:

When the aggregate is put into the drain bin 1, the water of the water inlet pipe 19 enters the water cavity 11 between the outer pipe 7 and the middle pipe 8 and is sprayed out through the nozzle 14 (water spray) to wash the aggregate from the drain bin 1, avoiding the problem that the aggregate near the center of the screen bucket cannot be washed well, ensuring the aggregate cleaning effect. Here, the outer layer of the aggregate can also be washed with a spray pipe to ensure that the inner and outer layers of the aggregate in the drain bin 1 are washed The airflow enters the air cavity 12 between the middle tube 8 and the inner tube 9, and is ejected from the nozzle 14 (jet) through the connecting tube 10 to dry inside the aggregate, thereby improving the drying efficiency and effect. If the drying efficiency is to be further improved, the power supply or heat source can be turned on, the heating element generates heat, and the air in the air cavity 12 is heated to increase the drying speed. After the drying is completed, the water source, air source, power source or heat source is turned off, the telescopic rod of the flip mechanism 4 is started, and the material is tilted to unload. After the aggregate is emptied from the drain bin 1, the next washing, drying and unloading work is started.
