Abstract: 1,101,453. Filter aid filter. SEITZ-WERKE G.m.b.H. 19 Feb., 1965 [22 Feb., 1964], No. 7172/65. Heading B1D. A filter aid filter in which liquid to be filtered on entering the filter vessel 18 is initially directed away from filter elements 19 through ports 17 to reduce turbulence, comprises a horizontal filter vessel 18 containing a number of disc shaped filter elements 19 with their outlets connected in parallel, the elements 19 resting one behind the other on substantially parallel horizontal supports 15 (16) within the filter vessel and the supports being mounted in turn on a fixed or movable filter closure member (10) carrying liquid inlet ports (11, 12) and outlet ports (14), each support 15 (16), comprising a hollow conduit, closed at one end, with its open end in communication with an inlet port and having outlet orifices 17 substantially outside the circumference of the filter element for directing incoming liquid towards the vessel wall and hence away from the filter elements. Each filter element 19 may comprise fine wire mesh stretched on frames and peripheral eyelets (21) which when joined together form a fluid outlet manifold from the elements. The pressure drop in the conduits in supports 15 (16) may be equalized by different cross-sections or changing the spacing of the orifices 17. The filter aid material may be asbestos fibres.
