Abstract
A pressure filter includes two continuous mating surfaces movable relative each other and a filter medium capable of being disposed therebetween. A surface, provided for supporting the filter medium, is bounded by and is substantially coplanar with one of the continuous mating surfaces. The filter further includes a shallow inlet cavity, bounded by the other of the continuous mating surfaces, and an inlet distributor in communication with the inlet cavity. The inlet distributor includes at least one opening and may be of internal or external type. When the mating surfaces are pressed together, a shallow filtration chamber is defined by the inlet cavity and the filter medium. The filter apparatus may include a plurality of shallow filtration chambers, stacked one above the other, and constructed as described above.
Claims18
A pressure filter for filtering viscous fluid slurry comprising:
- a first and a second continuous mating surfaces movable relative to each other and defining a volume open area therebetween when said mating surfaces are in contact with each other;
- a supporting surface bounded by and substantially coplanar with said first continuous mating surface and extending across said volume open area;
- a shallow inlet cavity further defining said volume open area on its sides bounded by said second continuous mating surface when in contact with said first continuous mating surface, on its bottom by said supporting surface, and on its top by the interior of said second mating surface;
- an inlet distributor in fluid communication with said shallow inlet cavity, said inlet distributor including means for directing said fluid slurry uniformity and evenly throughout said shallow filtration cavity to establish a complete filling of said shallow inlet cavity;
- and
- a filter medium capable of being disposed between said first and said second continuous mating surfaces, whereby a shallow filtration chamber is defined by said shallow inlet cavity and said filter medium when said first and said second continuous mating surfaces are pressed together, said shallow filtration chamber having a depth from about 0.25 of an inch to about 2.5 inches.
A pressure filter comprising:
- a plurality of first continuous mating surfaces and a plurality of second continuous mating surfaces, said pluralities of first and second continuous mating surfaces movable relative to each other;
- a plurality of supporting surfaces, each one bounded by and substantially coplanar with one of said plurality of first continuous mating surfaces;
- a plurality of shallow inlet cavities, each one bounded by one of said plurality of second continuous mating surfaces;
- a plurality of inlet distributors, each one in fluid communication with one of said plurality of shallow inlet cavities;
- and
- a plurality of filter mediums, each one capable of being disposed between one of said plurality of first continuous mating surfaces and one of said plurality of second continuous mating surfaces, whereby a plurality of shallow filtration chambers is defined by said plurality of inlet cavities and said plurality of filter mediums when said plurality of first continuous mating surfaces is pressed together with said plurality of second continuous mating surfaces, each of said plurality of shallow filtration chambers having a depth from about 0.25 of an inch to about 2.5 inches.
