<p>The self-cleaning filter particularly for high-viscosity pasty fluids has a fixed body (2) having a substantially cylindrical elongated chamber (5) in which a filtration drum (9) is supported and defines a central region (10), at one end of which there is an inlet (14) for the fluid to be filtered, and an outer annular region (11), at the other end of which there is a duct (20) for the removal of the filtered fluid; a shaft (23) is axially supported and rotationally actuated in the chamber (5) and has a helical crest (25) the profile whereof is suitable for grazing the inner surface of the drum (9) to remove therefrom the impurities which are present and is suitable for pushing the fluid toward an impurity discharge duct (21) arranged at the other end of the chamber (5), the constant cleaning of the drum (9) being suitable for keeping constant the pressure drop on the filter.</p> |
