The invention provides a sand suction air-lift device. The sand suction air-lift device comprises a sand suction tube, wherein the upper end of the sand suction tube extends into a sand discharging chamber; the upper portion of an extending end of the sand suction tube in the sand discharging chamber is transversely provided with a baffle which stops muddy sand from entering a fan; and the fan is arranged above the baffle. When silted river sand is required to be cleaned, the lower end of the sand suction tube extends in the silted river sand, the fan is started, the air pressure in the sand discharging chamber and the air pressure in the sand suction tube are reduced, the silted river which is in contact with the lower portion of the sand suction tube is sucked in the sand suction tube, after being sucked in the sand discharging chamber, the river sand in the sand suction tube impacts the baffle, then is discharged out of the sand discharging chamber and is collected, the silted river sand is cleaned, the height of the sand suction tube can be adjusted according to operation height, the inner air pressure of the sand suction air-lift device is reduced with the aid of the fan, working requirements can be met, and the baffle can effectively prevent the river sand from entering the fan. By the sand suction air-lift device, the silted river sand can be cleaned conveniently and efficiently.
