Abstract:
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.
