<p>1,064,918. Settling particles from fluids. WESTINGHOUSE ELECTRIC CORPORATION. Aug. 17, 1965 [Sept. 16, 1964], No. 35226/65. Headings B1D and BIT. In Fig. 2 liquid enters chamber 14 and flows inwards of one or more stacks 30 of generally frusto-conical baffles (Figs. 4, 5, not shown), the baffles being closely spaced and each having a central aperture whereby cleaned liquid enters perforate tube 26 and a plurality of circumferentially spaced, radially outwardly diverging troughs of V-shaped cross-section whose outer, lowermost ends have sludge exit ports (49), the various ports (49) in different baffles being aligned with sludge tubes 20 and the peripheral portions of the baffles being shaped to admit liquid only at locations circumferentially between the troughs to prevent eddy currents in the lower ends of troughs where solids are settling. Baffles may be stainless steel, butastyrene, polypropylene or P.V.C. In Fig. 2 the liquid receiving tubes 26 of each stack deliver liquid into a chamber 25, while sludge tubes 20 convey largely separated solids into lower chamber 29, and respective siphons 28, 22 carry liquid and sludge thence into chambers 15, 16, annualarly arranged round chamber 14. The outlet elbows 66. 67 of the siphons may be adjustable, and sludge chamber 16 may be partly-divided by triangular blocks 80 of foamed polyurethane (Fig. 6, not shown) between outlets (71). Further gravity separation may occur in chamber 16, clear liquid overflowing into chamber 15. The arrangement of Fig. 7 (not shown) is for separating particles from gases.</p> |
