ABSTRACT:
The apparatus serves the purpose of separating trash from less heavy firm articles in a flow of liquid. It has a casing wherein a horizontal revolving screen is located with members which impart motion to trash. Accomodated in the casing coaxially with the revolving screen is a contrivance for the separation, feeding and discharging of trash which is attached to the revolving screen at the end thereof where the flow of liquid carrying the uncleaned firm articles enters the revolving screen. The contrivance consists of an outward cylinder and an inward cylinder. The outward cylinder is provided with ports through which the outflow of liquid and the smaller particles of trash from the revolving screen are fed. Ports provided in the inward cylinder serve to admit the greater particles of trash and discharge all the trash separated. Partitions subdivide the space between the cylinders into passages extending transversely with respect to the longitudinal axis of the contrivance. Each of the passages opens into a corresponding port of the inward cylinder and into a port of the outward cylinder. At least one additional cylinder is coaxially disposed between the outward cylinder and the inward cylinder and provided with ports. At least three passages are formed in each, one length of each being defined by the side surfaces of the outward cylinder and the additional cylinder and another length being defined by the side surfaces of the additional cylinder and the inward cylinder.
