| 摘要 |
The present invention relates to a device for displacing sediment, for example sand, from the bottom of a liquid-filled container (20) to a receptacle device (29). A first conveyor (22) disposed in the edge region (21) of the container (20) in connection with the bottom of the container, receives sediment which is accumulated on the bottom. The first conveyor (22) consists of a rotating screw thread (24) located in a path (23) and has a discharge portion (27). The device further includes a second conveyor (40) consisting of a rotary screw thread (44) in a casing (41). The second conveyor (40) has an infeed opening (43) located in connection with the lower portion of the container, preferably below its bottom, and a discharge portion (42) located above the maximum filling level of the container (20). A mechanical device (50) displaces the sediment from the discharge portion (27) of the first conveyor (22) to the infeed opening (43) of the second conveyor (40). The discharge portion (42) of the second conveyor (40) discharges sediment to the receptacle device (29) either direct or via the transport device (60). |
