Abstract
A filter for removing solids from fluids has a three dimensional pleated refractory construct with a plurality of adjacent parallel angled walls. The opposed edge of each angled wall is integral with an edge of an adjacent angled wall to form upper apices and lower apices. An open mesh planar ceramic screen may be located adjacent to the upper and/or the lower apices of the pleated construct of the filter.
Claims14
A rigid ceramic filter for removing solids from fluids, said filter comprising a three dimensional pleated sintered ceramic construct having an inlet side, an outlet side and a plurality of adjacent angled walls having a sintered ceramic open mesh structure and opposed substantially parallel edges, said opposed substantially parallel edges of each of said angled walls being integral with an edge of an adjacent angled wall to form an apex, whereby said pleated sintered ceramic construct has a plurality of adjacent angled walls joined at upper apices lying in a first plane and joined at lower apices lying in a second plane, wherein said first and second planes are substantially parallel, and a first open mesh planar sintered ceramic screen adjacent to said upper apices of said pleated construct, whereby said first open mesh planar sintered ceramic screen is located at said inlet side of said pleated construct and said plurality of sintered ceramic open mesh adjacent angled walls are located below said first open mesh planar sintered ceramic screen.
A filter for removing solids from fluids, said filter comprising a stacked array of three dimensional, rigid pleated sintered ceramic constructs, wherein each construct has an inlet side, an outlet side and a plurality of adjacent angled walls having a sintered ceramic open mesh structure and opposed substantially parallel edges, said opposed substantially parallel edges of each of said angled walls being integral with an edge of an adjacent angled wall to form an apex, whereby said pleated ceramic construct has a plurality of adjacent angled walls joined at upper apices lying in a first plane and joined at lower apices lying in a second plane, wherein said first and second planes are substantially parallel, said filter further comprising a first open mesh planar sintered ceramic screen positioned adjacent to the upper apices of a first pleated construct in said stacked array, at least one open mesh planar sintered ceramic screen positioned between adjacent pleated constructs in said stacked array.
