Abstract:
1. A filter press system for separating a mixture of liquid and insoluble solids, said filter press system comprising: a frame comprising two parallel horizontal rails attached to a vertical end plate; and a plurality of filter plates configured to form a stack of parallel plates, each of said plurality of filter plates being movably attached to said frame, each of said plurality of filter plates hanging on said horizontal rails wherein the plane of each of said plurality of filter plates is parallel to said vertical end plate, said plurality of filter plates further being configured to form a multiplicity of chambers, each of said multiplicity of chambers being formed by adjacent filter plates of said plurality of filter plates, each of said multiplicity of chambers being lined by filter cloths, wherein said plurality of filter plates, said multiplicity of chambers and said filter cloths are configured to allow filtrate to escape from said chambers while retaining solids from said mixture to form a filter cake; wherein each of said plurality of filter plates comprises at least one side feed port and at least one delivery slot, said at least one side feed port being an aperture completely through the filter plate, said at least one delivery slot being a slot in the filter plate with a first end and a second end, each of said at least one delivery slots being connected to a corresponding one of said at least one side feed ports at said first end and to a corresponding one of said multiplicity of chambers at said second end, and wherein the second end is higher in the vertical plane than said aperture.
