摘要

1. Device for removing flushed material and solids from feeder flumes (1), in particular of effluent treatment plants, with a grate (6) which extends down to the bottom of the feeder flume, is liquid-permeable and substantially has the shape of a cylindrical shell and which merges into a conveying section for the rakings, which section is directed obliquely upwards, leads to the dumping point and is constructed as a screw conveyor unit (11) with a casing (12) and a screw shaft (13), characterised in that the grate (6) has a comparatively greater diameter than the casing (12) of the screw conveyor unit (11) and the part protruding above the water level is interrupted for about one quarter of its circumference, that the screw conveyor unit (11) is provided with a drop-in funnel (14), associated with the interrupted part (7) of the grate (6), for the rakings (22), and that the shaft of the screw conveyor unit (11) carries on its lower end at least one scraper arm (20) fitted with scraping members (21) for the grate (6).
