Abstract
A membrane plate, a filter plate, and a filter press. The membrane plate is outfitted with a filter element on top of the membrane on both side surfaces, and the membrane plate has retaining elements at a distance from the margin on which the filter elements are removably secured. The filter plate also has retaining elements at a distance from the margin on which the filter elements are removably secured.
Claims16
A membrane plate for a filter press, wherein the membrane plate comprises:
- a base body with two side surfaces and a margin, and a membrane of flexible material which is arranged on the base body on both of the two side surfaces, wherein the membrane plate is outfitted with two filter elements on top of the membrane plate such that one of said two filter elements is on one of said two side surfaces and the other of said two filter elements is on the other side surface, and the membrane plate has retaining elements located in a margin region at a distance from the margin, wherein the filter elements are removably secured on the retaining elements, wherein the retaining elements are arranged on the base body of the membrane plate, wherein the retaining elements are arranged outside a perimeter of the membrane, wherein the retaining elements extend perpendicular to planes E, E′ of the membrane elate, wherein planes E, E′ lie in the side surfaces of the base body with the planes E, E′ adjacent to the margin of the membrane plate, wherein the retaining elements are retaining pegs, wherein each of the retaining pegs has a truncated cone section, and wherein an undercut is provided on each retaining peg between the truncated cone section and one of the two side surfaces of the base body of the membrane plate.
A filter plate for a filter press, wherein the filter plate comprises:
- a base body with two side surfaces and a margin, and two filter elements arranged on the base body such that one of said two filter elements is on one of said two side surfaces and the other of said two filter elements is on the other side surface, wherein the filter plate has retaining elements located in a margin region at a distance from the margin, wherein the filter elements are removably secured on the retaining elements, wherein the retaining elements are arranged on the base body of the filter plate, wherein the retaining elements project outwardly relative to both side surfaces of the base body of the filter plate and extend perpendicular to two planes E, E′ of the filter plate, wherein planes E, E′ lie in the side surfaces of the base body with the planes E, E′ adjacent to the margin of the filter plate, wherein the filter elements have holes in which the retaining elements can be inserted, wherein the filter elements are filter cloths, wherein the retaining elements are retaining pegs, wherein each of the retaining elements has a truncated cone section, and wherein an undercut is provided on each of the retaining elements between the truncated cone section and one of the two side surfaces of the base body of the filter plate.
A filter press for liquid, comprising a plurality of parallel arranged:
- a) filter plates, b) filter frames, c) membrane plates and d) filter elements, wherein each filter plate comprises a base body with two side surfaces and a margin, two planes E, E′, and two filter elements which are arranged on the base body such that one of said two filter elements is on one of said two side surfaces and the other of said two filter elements is on the other side surface, wherein each filter plate has a margin region and has retaining elements located in the margin region, the retaining elements being located at a distance from the margin, wherein the filter elements are removably secured on the retaining elements, wherein the retaining elements are arranged on the base body of the filter plate, wherein the retaining elements project outwardly relative to both side surfaces of the base body and extend perpendicular to the two planes E, E′, wherein the planes E, E′ lie in the side surfaces of the base body with the planes E, E′ adjacent to the margin of the filter plate, wherein the filter elements have holes in which the retaining elements can be inserted wherein the filter elements are filter cloths, wherein the retaining elements are retaining pegs, wherein each of the retaining elements has a truncated cone section, and wherein an undercut is provided on each of the retaining elements between the truncated cone section and one of the two side surfaces of the base body of the plate;
- and each membrane plate comprises a base body with two side surfaces and a margin, and a membrane of flexible material which is arranged on the base body of the membrane plate on either of the two side surfaces of the membrane plate, wherein each membrane plate is outfitted with two filter elements such that one of said two filter elements of said membrane plate is on one of said two side surfaces of said membrane plate and the other of said two filter elements of said membrane plate is on the other side surface of said membrane plate, wherein each membrane plate has a margin region and has retaining elements located in the margin region, the retaining elements being located at a distance from the margin, wherein the filter elements of the membrane plate are removably secured on the retaining elements, wherein the retaining elements of the membrane plate are arranged on the base body of the membrane plate, wherein the retaining elements of the membrane plate are arranged outside of a perimeter of the membrane, wherein the retaining elements of the membrane plate are retaining pegs, wherein each of the retaining elements of the membrane plate has a truncated cone section, and wherein an undercut is provided on each of the retaining elements of the membrane plate between the truncated cone section and one of the two side surfaces of the base body of the membrane plate.
