Continuous liquid filtering apparatus with multi-layer sintered filtering element

A continuous liquid filtering apparatus comprising:

• a cylindrical filter housing;
• a preliminary filtering chamber having a liquid inlet and an elongated coarse filtering screen;
• a final filtering chamber having a cylindrical multi-layer sintered filtering element in liquid communication with said preliminary filtering chamber across said coarse filtering screen;
• a filtered liquid chamber in liquid communication with said final filtering chamber across said sintered filtering element and having a liquid outlet;
• and
• an electromechanical cleaning system adapted to remove sediments from the sintered filtering element;
• wherein said elongated coarse filtering screen and said cylindrical multi-layer sintered filtering element are coaxially aligned within said housing to form an annular envelope between an inner periphery of said housing and an outer circumference of each one of said screen and said sintered filtering element such that the preliminary filtering chamber and the filtered liquid chamber are two parts of said annular envelope, separated from each other by an inner rim positioned between the sintered filtering element and the inner periphery of the cylindrical filter housing, wherein said final filtering chamber is formed within the area defined by the inner circumferences of both said screen and said sintered filtering element.
