Sealing strip for sealing adjacent filter plate assemblies of a filter press, such as a tower press, a filter frame, a filter frame assembly and a filter apparatus

A sealing strip for sealing adjacent filter plate assemblies of a horizontal filter press, the sealing strip comprising:

• an elongate body extending along a length direction, and having first longitudinal end, a second longitudinal end and a cross-sectional profile;
• a base portion configured to be attached in a corresponding groove of an associated filter frame or filter plate assembly;
• a distal portion for sealing against an adjacent filter plate assembly, a ridge being provided on the distal portion for increasing a sealing pressure thereat, when the sealing strip is compressed against an adjacent filter plate assembly, and
• an intermediate portion between the base portion and the distal portion, wherein the intermediate portion has a width, defined along a lateral direction transverse and coplanar to the length direction, less than that of the base portion,
• wherein the sealing strip further comprises an elongate stiffener running along at least a part of the length of the sealing strip,
• wherein the stiffener is positioned at the base portion such that it intersects with a line running through the ridge and extending along a vertical direction, perpendicular to both the length direction and the width direction, as seen along the cross-sectional profile, and wherein the stiffener is encapsulated by the body of the sealing strip,
• wherein the stiffener is longitudinally spaced apart from both of the first longitudinal end and the second longitudinal end of the elongate body.
