ABSTRACT:
An apparatus for continuously removing waste materials from a water stream. The apparatus includes a rotating screen assembly formed by a plurality of articulated "L"-shaped links that form separate, laterally spaced closed loops. The space between the loops of links defines the maximum size of material that can pass through the apparatus without being removed from the stream. The respective truncate portions of the "L"-shaped links facilitate the lifting of the debris from the stream. The screen assembly is rotated by motor-driven sprocket segments that are positioned at the discharge end of the apparatus. These segments substantially occupy the spaces between the links when the links travel past the segments, and the occupation of the spaces by the segments displaces the waste materials from the spaces and dislodges the materials from the links as well so that the materials may fall under the influence of gravity to a receptacle. A blocking shoe and a protective shoe are among the important features of the apparatus; the blocking shoe prevents waste materials from flowing under the apparatus, and the protective shoe prevents materials from protruding into the interior of the screen assembly.
