Abstract
A multi-screw press for dewatering waste materials including a plurality of fixed filtering cylinders and a plurality of revolving filtering cylinders connected to the fixed filtering cylinders are installed within a single outer casing, and a plurality of tapered screws are located within the fixed and revolving filtering cylinders. The screws and the revolving filtering cylinders are driven by a single motor, so that the waste materials within the filtering cylinders are pressed by the screws and dewatered. A pressure adjusting device is located on the outlet of the screw press and is hydraulically driven. Any residue adhering to the filtering cylinders can be effectively washed away by the use of spray tubes.
