ABSTRACT:
A cleaning filter has a cylindrical tank through which an axial pipe extends, the pipe having a screw blade attached thereon and being rotatable in the tank. A drum rotatably carried on the axial pipe is disposed within the tank and around the screw blade, the drum having a cylindrical body and an end cover mounted on the cylindrical body such that the cylindrical body is rotatable relative to the end cover. The end cover has a cleansing agent inlet and a cleansing agent outlet with the cleansing agent being removed from the drum by rotating the pipe means and the screw blade, the latter engaging the cleansing agent in the drum to thereby move the cleansing agent axially to the cleansing agent outlet. A filter is disposed on the outer periphery of the cylindrical body of the drum so that when the liquid to be cleaned flows into the tank from an inlet and is discharged through an outlet on the axial pipe, the liquid passes through the filter and the cleansing agent in the drum to thereby remove impurities from the liquid.
