Rejector cartridge
A method of retrofitting a filter plate including a filtration zone and a frame surrounding the filtration zone for use in a filter press. The frame of the filter plate is altered to removably receive a filtrate cartridge, the filtrate cartridge constructed and arranged to facilitate flow out of a filtration chamber of the filter press associated with the filtration zone to a discharge port. The filtrate cartridge is inserted in the frame. Related filter plates and filter presses are also disclosed.
1 . A method of retrofitting a filter press plate, comprising:
providing a filter press plate including a recessed face defining a filtration zone and a frame surrounding the filtration zone;
altering the frame to removably receive a filtrate cartridge, the filtrate cartridge constructed and arranged to facilitate flow out of a filtration chamber formed by filtration zones of adjacent filter press plates to a discharge port; and
inserting the filtrate cartridge in the frame.
2 . The method of claim 1 , wherein the filtrate cartridge is positioned outside of the filtration zone of the filter press plate.
3 . The method of claim 2 , wherein the filtrate cartridge is positioned within a sealing area of the filter press plate.
4 . The method of claim 1 , wherein the filtrate cartridge is positioned in a corner of the frame.
5 . The method of claim 1 , wherein the filter press plate is not used to mount the filtrate cartridge.
6 . The method of claim 1 , wherein the filtrate cartridge does not extend into the filtration zone of the filter press plate.
7 . The method of claim 1 , wherein the filtrate cartridge is of modular construction.
8 . The method of claim 7 , further comprising bridging first and second components of the modular filtrate cartridge to accommodate a thickness of the filter press plate.
9 . The method of claim 1 , wherein the filtrate cartridge defines a plurality of flow channels.
10 . The method of claim 9 , wherein the filtrate cartridge is configured to reduce filtrate velocity and/or turbulence at the discharge port.
11 . The method of claim 9 , wherein the filtrate cartridge is configured to facilitate flow distribution and/or throughput in the filtration chamber.
12 . The method of claim 1 , wherein the filter press plate includes an integral manifold port to facilitate fluid communication with the discharge port via the filtrate cartridge.
13 . The method of claim 1 , further comprising plugging a preexisting outlet in the frame.
14 . The method of claim 1 , further comprising fluidly connecting the filtrate cartridge to the discharge port.
15 . The method of claim 1 , further comprising altering the frame to removably receive a second filtrate cartridge and inserting the second filtrate cartridge in the frame, wherein the first and second filtrate cartridges are on opposite faces and opposite sides of the filter press plate.
16 . The method of claim 1 , further comprising installing the retrofitted filter press plate in a filter press.
17 . The method of claim 16 , further comprising introducing a source of a slurry to the filter press for separation.
18 . The method of claim 17 , wherein the source of the slurry is associated with a mining operation.
19 . The method of claim 16 , further comprising taking the filter press offline and replacing the filtrate cartridge in the filter press plate after a predetermined period of time.
20 . The method of claim 16 , further comprising retrofitting at least two filter press plates and installing the at least two retrofitted filter press plates in the filter press.
