<p>A device (1; 100) for filtering liquid substances comprises a container (2) to which two pipes (30, 34) are connected, respectively an inlet pipe and an outlet pipe for a liquid substance mixed with sediment. The inside of the container (2) mounts a shaft (10) that rotates about a longitudinal axis (3) and that has a coaxial cavity (11) made in a part of it and leading out of the container (2) at one end of the shaft (10). The shaft (10) mounts in a substantially rigid manner a plurality of filtering elements (18) and has coaxially keyed to it an impeller (12) of a hydraulic motor (13) housed inside the container (2), where a pipe (16) is designed to direct a flow of liquid substance mixed with sediment in such a way as to cause the shaft (10) to turn during cleaning of the filtering elements (18). <IMAGE></p> |
