Abstract

1357202 Filter element JESSEL CO Ltd 18 April 1972 [1 May 1971] 12607/71 Heading B1D A filter element adapted to support an outer layer of filter aid in use comprises a perforate tube 2 carrying a layer of wire mesh secured thereto by wires 10, wrapped round the tube and secured to end fittings thereof, the wires being triangular or rectangular in cross-section. In Fig. 6 triangular wires have one face abutting the wire mesh 11 so that reverse flow of water or carbon dioxide easily removes the filter cake. In Fig. 4 square-sectioned wires have one corner abutting the wire mesh, which is stated to facilitate cleaning by creating channels between wires and mesh round which the cleaning fluid flows quickly to break up the cake. Fig. 5 (not shown) illustrates triangular wires corner-on to the mesh. Figs. 1 to 3 (not shown) illustrate other constructional details of the element, which are fully detailed in Specification 1,357,201.
