Conical filter with turbine powered scraper

A fluid powered self-cleaning filtration apparatus comprising:

• a filter housing (4) defining an interior volume, the filter housing (4) including a fluid inlet (302) at an upper end of the filter housing (4) for introduction of a liquid to be filtered into the interior volume, and a first outlet (402) located at a bottom of filter housing (4);
• a conically shaped fluid permeable filter (10) disposed within the interior volume, the conically shaped fluid permeable filter (10) having a largest cross-section at the upper end of the filter housing (4) and a smaller cross-section at a lower portion of the filter housing (10) defining a receptacle that liquid to be filtered is introduced into by fluid inlet (302), with introduced liquid being displaced through the filter (10) due to the force of the volume of liquid present in the filter, producing a filtrate which may exit the filter housing (4) through the first outlet (402);
• a rotatable cleaning structure (20) for cleaning the filter (10), wherein the rotatable cleaning structure (20) includes:
• at least one scraper (201) within the receptacle extending along and substantially abutting a first surface (101) of the filter (10), the at least one scraper (201) being rotatable with respect to the first surface (101) of the filter (10);
• and
• a plurality of rotatable elements (250) rotationally engaged with the at least one scraper (201);
• an actuating inlet (300) for providing a stream of water, an outlet of the actuating inlet (300) is arranged to direct the stream of water towards at least one of the plurality of rotatable elements (250) to provide a rotational force to the rotatable elements (250), which causes the scraper (201) to rotate along the first surface (101) of the filter (10).
