Abstract
A filter plate for a horizontal plate and frame-type filter, such as a tower press. A filtrate vat formed on, and integral with a filter plate is provided along with an outlet opening as a gap on a border delimiting the vat for providing drainage route, and a recessed portion provided at the outlet opening. A rigid structure of the filtrate vat that is capable of resisting deformation may be achieved, and contamination from slurry between the filter plate and a possible vat liner or coating is avoided.

A filter plate for a horizontal plate and frame-type filter, such as a tower press, the filter plate having a rigid plate-like body with a frame side and a vat side,
- wherein the filter plate comprises, on the vat side, a border having at least an inner lateral wall and an upper surface, the border being elevated for a distance at least from a portion of the filter plate delimited within the border, and
- wherein the border is an integral part of the filter plate,
- wherein a filtrate vat is formed by the filter plate, such that the inner lateral wall of the border forms a lateral wall of the filtrate vat, and a portion of the filter plate delimited by the border forms a bottom of the filtrate vat,
- wherein a gap is provided on the border, such that an outlet opening extending laterally through the border is formed, thereby providing a fluid drainage route from the filtrate vat, and wherein the filter plate comprises, on the vat side of the filter plate, a recessed portion of the filter plate situated at the outlet opening, the recessed portion being recessed with respect to the bottom of the filtrate vat.
