Abstract
A filter configured to separate the solid components and the liquid components from a slurry. The filter includes a plurality of filter plate assemblies that cooperate to define a plurality of filter chambers, each defining a perimeter having an open section when the filter plates are in a closed position relative to one another. Each filter plate assembly includes a closure configured to close the open section. Preferably, the closures are movable to an open position to permit a particulate cake to be removed from the filter chambers without separating the filter plates.
Claims19
A filter plate assembly, comprising:
- a first filter plate having a first surface;
- a second filter plate having a second surface facing said first surface, said first and second filter plates movable between an open position and a closed position relative one another, wherein in said closed position an interior portion of said first surface is spaced from an interior portion of said second surface to define therebetween a filter chamber having a perimeter;
- wherein said filter plate assembly is capable of creating a seal between said first filter plate and said second filter plate, thereby defining a sealed section of said perimeter, said sealed section extending a length less than an entire length of said perimeter such that said filter plate assembly also defines an open section of said perimeter, said open section being sized and shaped to occupy a substantial entirety of a side of said perimeter such that an entirety of the particulate cake can be removed from said filter chamber;
- and
- a closure configured to be movable in a linear direction between a first position closing said open section and a second position not closing said open section, said closure further being capable of sealing said open section of said perimeter in said first position.

A method of filtering, comprising:
- forming a sealed filter chamber with a filter plate assembly comprising a first filter plate, a second filter plate, and a closure, said first filter plate and said second filter plate being movable from an open position to a closed position relative to one another and a closing force applied to said first and second filter plates to partially close said filter chamber, thereby defining an open section of said filter chamber, said closure being configured to close said open section of said sealed filter chamber;
- introducing a slurry into said filter chamber;
- forcing a liquid component of said slurry through a filter media lining a least a portion of said filter chamber until a particulate cake is formed within said filter chamber, said particulate cake occupying a substantial portion of said filter chamber;
- reducing said closing force and maintaining said first filter plate and said second filter plate in said closed position;
- removing said closure in a linear direction;
- and
- discharging said particulate cake through said open section of said filter chamber.
