#$%^&*AU2020101642A420200917.pdf#####Abstract The invention provides a sediment circulation and flow control system for sedimentation trough, which comprises: a water tank for storing water; a water-sediment mixing tank for receiving water and sediment to form a water-sediment mixture; a trough for performing sedimentation simulation experiments, which has an upper nozzle and a lower nozzle; a water pump, which is provided with: a pumping port for pumping water from the water tank; a first drainage port for supplying a part of the water pumped by the water pump with the watersediment mixing tank; and a second drainage port for returning the rest of the water pumped by the water pump to the water tank; a sediment-filter device which receives the watersediment mixture discharged from the trough and separates the water and sediment from the water-sediment mixture and returns the separated water to the water tank; and a conveyor for conveying the separated sediment from the sediment-filter device to the water-sediment mixing box. The system of the invention can realize water circulation and sediment circulation simultaneously, and can use a large flow water pump with low price to realize quantitative control of water flow and reduce cost.Drawings of Description 9A Water-sedient Tank 191 31 5 t-. 1be Wadiment-filte 82 Water 318112 40 32 e. 95 Water Tank Figure 1 60 water-se11ent Miture 10 Water seament 2 5 Figure 2 1/1
