Abstract
Provided is a fluid filtration assembly including a housing configured with one or more filter units extending in fluid flow between a raw fluid inlet port and a filtered fluid outlet port, a filter rinsing assembly being in fluid communication with a rinsing fluid inlet port, and propulsion fluid inlet port being in flow communication with a propulsion mechanism for propelling one or both of the filter rinsing assembly and the filter unit with respect to one another. Further provided is a thread tensioning mechanism for controlling tension of coiled threads of a thread-type filtering cartridge.
Claims18
A fluid filtration assembly comprising a housing configured with one or more filter units extending in fluid flow between a raw fluid inlet port and a filtered fluid outlet port;
- a filter rinsing assembly being in fluid communication with a rinsing fluid inlet port;
- and propulsion fluid inlet port being in flow communication with a propulsion mechanism for propelling one or both of the filter rinsing assembly and the filter unit with respect to one another.
A thread tensioning mechanism for controlling tension of coiled threads of a thread-type filtering cylinder, said tensioning mechanism comprises an array of thread supports, axially extending and being radially displaceable between a tensioned filtering mode and a loose rinsing mode, respectively.
A core structure for supporting thread coils of a thread-type filtering cylinder, said core structure comprising a ridged cylindrical structure configured with a plurality of axially extending spacers radially projecting from an external surface defined by the cylindrical structure, defining a filtration space between said external surface and a perimeter defined by said plurality of spacers, said filtration space being in flow communication with one or both an inside space within the cylindrical structure and end plates of the cylindrical structure.
A fluid flirtation system comprising a housing accommodating a plurality of filtration units parallely disposed within the housing and a cleaning assembly within the housing, wherein one or both of the filtration units and cleaning assembly are rotatably disposed within the housing to facilitate rinsing of filtering media of the filter units.
