Abstract

161,735. Linden, L. Jan. 28, 1920. Plant; gravity-separation apparatus.-In apparatus for separating suspended matter from a liquid stream by successively subjecting it to abrupt upward, downward, and again upward deflection, with consequent changes of velocity in the neighbourhood of quiescent zones, means are provided for separately collecting and discharging from said zones the separated matter of different specific gravities. The apparatus shown comprises a central tube c and concentric vessels d, f, g, of similar configuration and of such a size that liquid supplied through a pipe a to the tube c and overflowing into a discharge trough g<3> flows intermediately through passages between the several vessels having a successively increasing cross-section. Vertical plates or rings e, h, j, are provided as baffles in the positions shown. Heavy matters settle into pockets d<2>, g<2> of the vessels d, g, and light impurities rise to the sur. face in the vessels d, f and can be floated off at intervals through a trough d<4> or troughs d<5>, d<6>. Separation can be aided by the supply of steam or other heated medium through perforated pipes q, r, s, s<1>, and of air through a pipe s<2>, which is situated in the opening d<3> between the vessels d, f and has perforations directing the air into both vessels. The pipe a may deliver the liquid on to a perforated basket p containing a solid reagent. Lime in solution may be supplied to the pocket d<2> through a small central pipe v. Water and chemical for cleansing may be directed along the bases of the vessels frcm perforated tube rings t, t' t<2>.
