Abstract
A filter for removing solids from a liquid of the type wherein a rotatable basket or drum has media inside straining from inside out. A power operated conveyor is mounted in the drum above the axis of rotation for receiving and positively removing solids. Thus, a liquid level is possible above the axis of rotation but below the conveyor so that a large filter area is in contact with the liquid while not interfering with the operation of the conveyor. A retractable scoop is provided for positively delivering the solids to the conveyor with an alternate sealing arrangement. A discharge ramp is carried adjacent an end of a baffle which extends above a liquid inlet upwardly toward the conveyor and is spaced from an inner wall of the drum to collect solids therebetween and accommodate the scoop for their removal. An improved means for equalizing the distribution of the liquid within the drum is also provided.
