Abstract
A filter plate assembly for a filter press is provided. The filter plate assembly includes at least a first filter plate and a second filter plate, which cooperate to define a filter chamber when the first filter plate and the second filter plate are in a filtering position. At least one of the first filter plate and the second filter plate is movable from the filtering position to a discharge position in which a filter cake can be discharged. In other configurations, the filter plate assembly can include a first filter plate, a second filter plate and a center filter plate or frame, which cooperate to define a filter chamber. The center filter plate or frame is movable from a filtering position to a discharge position.
Claims23
A filter plate assembly, comprising:
- a first filter plate having a first face and a first edge surface coinciding with a first edge of the first filter plate;
- and
- a second filter plate having a second face and a second edge surface coinciding with a second edge of the second filter plate, the second edge of the second filter plate facing in a same direction away from an operational axis as the first edge of the first filter plate;
- wherein the first filter plate and the second filter plate have a filtering position in which the plates are aligned with one another along the operational axis and the first face and the second face cooperate to define opposing ends of a filter chamber, wherein the first face is configured to support a first filter media and the second face is configured to support a second filter media, wherein a particulate cake formed within the filter chamber has a maximum width equal to a distance between the first face and the second face in a direction along the operational axis;
- wherein the first filter plate is movable out of alignment with the second filter plate in a direction perpendicular to and away from the operational axis to a discharge position in which the particulate cake can be discharged from a portion of the filter chamber defined by the at least one of the first filter plate and the second filter plate, wherein, in the discharge position, the first edge surface is located in a position past the second edge surface.

A filter plate assembly, comprising:
- a first filter plate having a first side surface and a first edge surface, the first side surface comprising a first cavity and the first edge surface coinciding with a first edge of the first filter plate;
- and
- a second filter plate having a second side surface and a second edge surface, the second side surface comprising a second cavity and the second edge surface coinciding with a second edge of the second filter plate, the second edge of the second filter plate facing in a same direction away from an operational axis as the first edge of the first filter plate;
- wherein the first filter plate and the second filter plate have a filtering position in which the plates are aligned with one another along the operational axis and the first cavity and the second cavity cooperate to define a filter chamber with the first side surface and the second side surface define opposing ends of the filter chamber, wherein the first side surface is configured to support a first filter media and the second side surface is configured to support a second filter media, wherein a particulate cake formed within the filter chamber has a maximum width equal to a combined depth of the first cavity and the second cavity in a direction along the operational axis;
- wherein at least one of the first filter plate and the second filter plate is a movable plate that is movable in a direction perpendicular to and away from the operational axis and out of the filtering position to a discharge position in which the particulate cake within the respective one of the first cavity and the second cavity can be discharged, wherein, in the discharge position, the first edge surface is located in a position past the second edge surface.

A filter plate assembly, comprising:
- a first filter plate having a first side surface;
- a second filter plate having a second side surface;
- a center plate having an outer surface and an interior region, said center plate configured to be movable between an aligned position and a separated position relative to the first filter plate and the second filter plate,
- wherein the first side surface is configured to support a first filter media and the second side surface is configured to support a second filter media, wherein a particulate cake formed within the filter chamber has a maximum width equal to a depth of the center plate in a direction along the operational axis,
- wherein in said aligned position the center plate is held in place between the first side surface and the second side surface and a perimeter seal is created around the interior region between the center plate and the first side surface of the first filter plate and between the center plate and the second side surface of the second filter plate, and
- wherein in said separated position the first filter plate and the second filter plate separate from the center plate a distance, said distance permitting the center plate to drop or move toward or to the separated position, whereupon the particulate cake is discharged can be discharged from the interior region of the center plate.
