Abstract: A separator includes a continuous inclined screening belt that passes over an upper roller and a lower roller to screen debris from municipal wastewater. The debris is then conveyed to a debris discharge outlet. A puddle of debris-laden wastewater forms a hydrostatic pressure head on the upper surface of the screening belt to assist in forcing the wastewater through the screening belt. Wastewater that passes through apertures in the screening belt is deflected by a deflector plate that shields the return path of the screening belt. The screened wastewater is then directed to the wastewater outlet. In a preferred embodiment, a belt-cleaning brush is disposed along the return path and brushes clinging debris from the screening belt toward the debris discharge outlet. Additionally, the screening belt rides on and is supported by a perforated backing plate as it travels from the lower roller to the upper roller.

Abstract: Apparatus to remove dust, fibers, lint or other undesirable particles from air. Air ladened with dust, lint or other undesirable matter is drawn into a filtering housing to contact the surface of a rotatable screen-covered drum. The air passes through the drum while the particles remain on the drum surface. The air passes from a higher pressure area exterior of the drum into a lower pressure area within the center of the drum and is conveyed away. The particles are retained on the exterior surface of the drum which is covered by the fine mesh screen. The particles, which form a bat, are then separated from the rotating drum surface by being moved into contact with a smooth compressor roll cooperating with a flighted doffing to lift away the bat from the drum and drop it to a collection zone. Fixed rubber seals are located to contact the rotating edges of the drum.
