ABSTRACT:
A device for removing waste material screened or filtered out of liquid flowing through a channel (1) has a basket-type interceptor (6) that is slanted and cylindrical and that rotates subject to power, extends to some extent into the liquid, and has its upstream face (8) open and its downstream face (9) solid. A conveyor (13) is positioned coaxially in relation to the interceptor, leads to a waste-material deposit point outside the liquid, accommodates a powered conveyor screw (18), and has an intake scoop (15) in the vicinity of the interceptor for collecting the waste material. A mechanism positioned stationary above the intake scoop releases waste material from the interceptor. The interceptor consists of a number of continuous annular disks (8) distributed along the outer surface with gaps between them and the waste-material releasing mechanism is a raker-stripper (28) that at least to some extent extends through the gaps between the annular disks.
