Abstract
A device for removing screened or sifted material from liquid flowing in a gutter (1) has a sloping cylindrical grizzly (11) that is mounted in the gutter, that is partly immersed in the liquid, and that has a face that is open upstream and closed downstream. The device also has a conveyor (5) that is positioned coaxial to the grizzly, that leads to an ejection point (18) outside of the liquid, and that has a powered shaft (7) and a housing (6). The conveyor has an intake funnel (9) for the screened or sifted material in the vicinity of the grizzly. The device also has a separator (15) for the screened or sifted material positioned above the intake funnel. The grizzly (11) is rotated. The separator (15) is positioned stationary on the outside of the grizzly (11) and releases screened or sifted material that adheres to the inside of the grizzly.
