Embodiment
As depicted in figs. 1 and 2, the utility model comprises skid base 18, the air lift part, be installed in the sediment by rotational flow machine and the grit water separator 17 that is installed in skid base 18 opposite sides of skid base 18 1 sides, described sediment by rotational flow machine comprises settling pit 6, sediment outflow pipe 2, stir shaft 4 is with the top that is installed in settling pit 6 and be used for the drive unit that driving stir shaft 4 rotates, top one side of described settling pit 6 is provided with influx 14 and spout 15, the bottom of described settling pit 6 is connected with sand removal pipeline 16, described stir shaft 4 is installed in the inside of settling pit 6, on the described stir shaft 4 agitating vane 5 is installed, one end of described sediment outflow pipe 2 stretches into the bottom of settling pit 6, and the water-in 7 on the casing 8 of the other end of described sediment outflow pipe 2 and grit water separator 17 is communicated with; Described air lift partly comprises roots blower 13 and inlet pipe 3, described roots blower 13 is installed on the skid base 18 that is positioned at grit water separator 17 belows, one end of described inlet pipe 3 is connected with roots blower 13 air outlets, and the other end of described inlet pipe 3 stretches into sediment outflow pipe 2 one ends that are positioned at settling pit 6 bottoms and communicates with sediment outflow pipe 2.
