Abstract
A filter (20) configured to separate the solid components and the liquid components from a slurry. The filter (20) includes a plurality of filter plate assemblies (46) that cooperate to define a plurality of filter chambers (70), each defining a perimeter (96) having an open section (98) when the filter plates (68) are in a closed position relative to one another. Each filter plate assembly (46) includes a closure (104) configured to close the open section (98). Preferably, the closures (104) are movable to an open position to permit a particulate cake to be removed from the filter chambers (70) without separating the filter plates (68).
Claims33
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 permit particulate cake to be removed from said filter chamber;
- and
- a closure configured to be movable 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 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;
- maintaining said first filter plate and said second filter plate in said closed position;
- removing said closure;
- and
- discharging said particulate cake through said open section of said filter chamber.
A filter press, comprising:
- a frame including a support surface;
- a stationary head;
- a movable head;
- a plurality of filter plates supported by said support surface between said stationary head and said movable head, said plurality of filter plates being movable relative to one another along said support surface between a separated position and a condensed position;
- a force generator configured to apply a force to said movable head in a direction toward said stationary head to squeeze said plurality of filter plates between said movable head and said stationary head;
- wherein adjacent pairs of said filter plates are configured to form a partially-sealed filter chamber when said force generator applies a sufficient force to create a seal between said plurality of filter plates, a perimeter of said filter chamber comprising an open section;
- a closure configured to close said open section, said closure being removable from said open section to permit particulate to be removed from said filter chambers with said plurality of filter plates in said condensed position.
A filter plate assembly for a filter, comprising:
- a first filter plate;
- a second filter plate, said first and second filter plates cooperating to create a filter chamber defining a width between said first and second filter plates when said filter plate assembly is in a closed position;
- a stay boss extending substantially across an entirety of said width of said filter chamber and being removable from said filter chamber.
A filter media assembly for a filter plate, the filter plate including a groove bounding a filter chamber portion of the filter plate, said filter media assembly comprising:
- a filter media portion configured to permit liquid to pass through the filter media portion and inhibit particulate matter from passing through the filter media portion;
- a seal secured to a periphery of said filter media portion and configured to be received within the groove of the filter plate.
