Abstract

1412975 Filter elements KRALOVOPOLSKA STROJIRNA NARODNI PODNIK 1 Nov 1972 [18 Nov 1971] 50255/72 Heading BID A liquid filter element comprises a coarse mesh wire support 1 and a fine mesh filter screen 2 both secured within a peripheral frame 3 and to ribs 4 which bridge the frame by joints 5 and 6. Frame 3 may be of U- section or comprise two flat sections (Fig 2, not shown) with joints 5, 6 being effected by adhesive or by heat and pressure bonding, ribs 4 being formed as part of the frame. Alternatively frame 3 and ribs 4 are moulded directly onto the support and screen and made of plastics (Fig 4 not shown). Fig 1 (not shown) illustrates various rib configurations. The elements may be flexible enough to accommodate to cylindrical surfaces when used in drum or belt filters for water/effluent treatment.
