Abstract
A filter member for horizontal disc filters has a base plate having a peripheral edge and a hub connected to the base plate. The base plate has cavities extending in a radial direction of the base plate at a slant toward the hub, wherein the cavities are positioned closely adjacent to one another. The base plate has narrow projections formed between the cavities. A filter medium, providing a support for deposition filtration and cake-forming filtration, is formed as a thin filter plate with very small openings. The hub, the projections between the cavities, and the peripheral edge have support surfaces for supporting the filter plate. The filter plate is at least partially connected to these support surfaces by material bonding such as welding.
Claims22
A filter member for horizontal disc filters (1), said filter member comprising:
- a base plate (13) having a peripheral edge (14);
- a hub (12) connected to said base plate (13);
- said base plate (13) having cavities (19) extending in a radial direction of said base plate (13) at a slant (G) toward said hub (12), wherein said cavities (19) are positioned adjacent to one another;
- said base plate (13) having projections (16, 17, 18) formed between said cavities (19);
- a filter medium configured to form a support for deposition filtration and cake-forming filtration;
- wherein said filter medium is formed as a filter plate (22) with openings (31);
- wherein said hub (12), said projections (16, 17, 18) between said cavities (19), and said peripheral edge (14) have support surfaces (15, 25, 26, 27) configured to support said filter plate (22);
- wherein said filter plate (22) is connected at least to portions of said support surfaces (15, 25, 26, 27) by material bonding.
