Abstract (en)
[origin: WO9845020A1] The invention relates to a device (1) for separating solid and/or semi-solid substances (3) located in a liquid (2), in which the device includes a container (10), a first sloping screw conveyor (20) and a second sloping screw conveyor (30). The first conveyor has a first portion (22) which forms a channel in the bottom of the container. Bodies of a density exceeding that of the liquid are accumulated in the channel by sedimentation. The first conveyor displaces the accumulated bodies up out of the liquid. The second conveyor (30) has a lower portion (32) located in the liquid (2), in which portion the path of the conveyor is provided with screen openings (42) for the passage of liquid during separation of solid and/or semisolid bodies (3) accompanying the liquid. The second conveyor (30) displaces the separated bodies from the lower portion of the conveyor, at the same time as the screen openings are cleaned. The screen openings discharge in a recepient (50) whose liquid level determines the liquid level in the container (10) and thereby determines the liquid flow through the screen openings.
