Abstract
A means separates solid matter from liquid and includes a perforated separation panel through which the liquid can pass and which prevents the passage of the solid matter of a size larger than a predetermined size. When solid matter becomes located against the panel, the flow of liquid along the face of the panel on which the solid matter is located will tend to cause the solid matter to move from the panel so that the panel is self cleaned and does not become obstructed by the solid matter.
Claims27
An apparatus for separating solid or particulate matter from a liquid flowing through said apparatus in a direction of flow through said apparatus along a flow path from an inlet to an outlet, said apparatus comprising:
- a chamber member providing a chamber with an inlet and an outlet so that said chamber is configured to contain a volume of said liquid;
- a separation panel of expanded metal mesh positioned in said flow path of said liquid and positioned in said chamber so as to be at least partly submerged in said volume, said separation panel having a face along which said liquid passes in a predetermined direction, said separation panel having a plurality of openings of a predetermined size, with each opening having a dimension in any direction being substantially smaller than a panel dimension in that direction, said openings being disposed at an angle to said direction of flow of said liquid,
- wherein said separation panel has a plurality of protruding segments adjacent said openings, with each segment extending from said face of said panel at a position upstream of a respective one of the openings to project into said flow path to form a substantially closed face to said liquid flowing in said direction of flow such that liquid flowing through said openings will only contain solid or particulate matter smaller than said predetermined size and such that, in use, solid or particulate matter larger tan said predetermined size is substantially prevented from adhering to or obstructing said separation panel.
An apparatus for separating solid or particulate matter from a liquid flowing through said apparatus in a direction of flow through said apparatus along a flow path from an inlet to an outlet, said apparatus comprising:
- a separation panel positioned in said flow path of said liquid, said separation panel having a face along which said liquid passes in a predetermined direction, said separation panel having a plurality of openings of a predetermined size, with each opening having a dimension in any direction being substantially smaller than a panel dimension in that direction, said openings being disposed at an angle to said direction of flow of said liquid,
- a flow diverter baffle disposed parallel to and spaced from said separation panel to allow recirculation of said liquid and contain floatables;
- wherein said separation panel has a plurality of protruding segments adjacent said openings, with each segment extending from said face of said panel at a position upstream of a respective one of the openings to project into said flow path to form a substantially closed face to said liquid flowing in said direction of flow such that liquid flowing through said openings will only contain solid or particulate matter smaller than said predetermined size and such that, in use, solid or particulate matter larger than said predetermined size is substantially prevented from adhering to or obstructing said separation panel.
An apparatus for separating solid or particulate matter from a liquid flowing through said apparatus in a direction of flow through said apparatus along a flow path from an inlet to an outlet, said apparatus comprising:
- a separation panel positioned in said flow path of said liquid, said separation panel having a face along which said liquid passes in a predetermined direction, said separation panel having a plurality of openings of a predetermined size, with each opening having a dimension in any direction being substantially smaller than a panel dimension in that direction, said openings being disposed at an angle to said direction of flow of said liquid,
- a receptacle for collecting said solid or particulate matter;
- wherein said separation panel has a plurality of protruding segments adjacent said openings, with each segment extending from said face of said panel at a position upstream of a respective one of the openings to project into said flow path to form a substantially closed face to said liquid flowing in said direction of flow such that liquid flowing through said openings will only contain solid or particulate matter smaller than said predetermined size and such that, in use, solid or particulate matter larger than said predetermined size is substantially prevented from adhering to or obstructing said separation panel.
