To all 'whom t may concern:
Be it known that ly Cinus'rorrun n. Cinna- TENSEN, a citizen of the United States, residing at Portland in theycounty of Multnomah and State ottlregon, have 'invented certain ne and uselnl Improvement s in Centrifugal Concentrators; and l do declare the following to `be a tull, clear, and ,exact dcscription of the invention, such as 'ill enable others skilled in the artto which 1t appertains toma lie and use the same.
This invention relates to separators, and more .especially to those wherein the concentrates are, separated Yfrom the tailings by eentiritugal action; and the object of the same is to improve the construetimi ol" a machine oft this character and greatly simplify the same while increasing` the output.
The obfeets are accomplished by building the machine in the manner hereinafter more fully described and claimed, and as shown in the drawings wherein Figure l is a central vertical. section through this machine complete, andltigrs. 2 and 3 are cross sections on the lines 5)-2 and of Fig. l.
lu the preferred .embodiment of my invention shown in the drawings attached a framework l supports a fixed launder trough 2 t'or the tailings or taste, thrsauie having a suitable outlet 5 and a closed top with a rather wide flange 8 projecting1 inward over and spaced above the inner wall 3 et the trough so as to leave an ann lar inlet, t) between them.
ll'lountefd in suitable bearings lO and wit-hin the framework is an upright sha'lt l2 which may be rotated in any suitable manner, as by having a power wheel 13 connected by belt with a suitable source ol energy; and secured to said shaft are spidersl 20 carrying an upright cylinder 2l whose open upper end or month stands adjacent the inlet tl into the launder and whose lower end carries a ringe` shaped head Q5 having` a central openingl 2li. Through the latter projects an upright sleeve 2T surroluuliug the lower end ot the shattV l2 and its` step bear ing' 1l and lteepingr them clean, which sleeve rises from the bottom ol a evlindrie-.rl inlet n'ienlber or pan throueh whose walls` at dit"- ferent: levels are connected the outlet and inlet pipes QS and 2f) as shown. lhe turnier opens troni the annular spare 2l() around the sleeve 27 and above a false bottom lh and '1li '---t'he pipes 34 into the cylinder wherein it such space/is in communication tln'fuigh the open top o t' the pan withv the opening` 2G at the lower end ot the cylinder. The inlet pipe 29 (anninunicates with the annular space l around the Sleeve 2 below said :false bottoni 3l, and above the true bottom 33 ot the pan, and troni the false bottoni rise several' pipes Bil which err tend upward tl'irtnighout the height ot but not in communication with the annular space 30, and then still farther upward through the openingt with their upper ends deflected radially outward within the cylinder above its lower head Thus the annular space 30l constitutes a second lann der or trough Ator receivinfblr the values which pass ott` the hard 25 and through the open 'ng 2G and are drawn oft at 28 in a manner indicated by the arrows; whereas the space 32 is a part oi the feed inlet. because the material ted in through the pipe 2t) passes around within this space and is delivered through the several pipes into the lower portion of the cylinder above its head 25. it perforated water pipe 3G is carried by and beneath said tiange 8, and the supply of water thereto inay be regulated so thatI its pertorations deliver water onto the interior ot the cylinder in quantities and at times regulated by the cock 37 or in any suitable way. Y
"he operation ot the invention is as fob lows: .il solution of ground ore and water in proper proportions (slime or pulp) is fed through the feed pipe 29 and passes up is driven 'adially outward by centrifugal force. lllhile it is possible to insert a liner within the cylinder as indicated at itl in Fig. l7 l prefer to mix the pulp to such consistency and speed up the cylinder to such a degree that the pulp will. accumulate within the cylinder to form its own liner, the grade from the bottom ot the cylinder um ward being about Ffe. However, whether the liner is inserted separately or is built up in this manner, at't'er it becomes established the water andI lighter materials pass upward over its inner tace under the influence of centrifugal torce, over the edge ot the cylinder as at il, and into the waste trough or launder 2; while the minerals or heavier particles accumulate against the inner tace of the liner and do not flow ott with the lighter particles because ot their llt) i the launder trough 30. Thereafter the water is turned off, the speed of rotation again 'increased, more slime or pulp :ted to the machine, and the operation is repeated. The concentrates thus washed out into the launder'O will be found to consist of sand, grit, and line minerals; and' after being cleaned, a good product is produced and'from which the minerals can be separated easily on a Atable'by any of the well known processes For dilerent ores or ores of different gradesl and weight, and perhaps on account of other conditions, the speed of rotation may be varied as the necessity of the case will require, and also the Volume of water may be varied as the expert operator will soon discover.
The ent-ire machine is of a size proportionate to the work to be accomplished, and its materials and speciic construction are matters of no moment, as changes therein may be fnade solong as the spirit ofthe invention is retained.
What is claimed asnew is 1. In a centrifugal separator, the combi nation 'with an upright rotary cylinder whose lower end carries a ring-shaped head, and an aXial shaft supporting said cylinder; of an open-topped pan disposed below the cylinder with its upper edge standing under said head, a false bottom therein producing a loper space, a feed pipe communicating with this space, a plurality of pipes extending through said false bottom from this space upward through the opening in said ring-shaped head of the cylinder and havnoemer ing their upper ends directed radially outward within the latter, an outlet pipe i'or the values opening through the wall of the pan abovesaid false bottom, an upstanding sleeve rising from the true bottom of the pan of an opent-opped pan beneath the cylinderV whose upper end stands beneath said head, a false bottom therein producing a lower space, a feed pipe communicating with this space, a plurality or' pipes extending through said false bott-om from' this space upward vand communicating with the interior of the cylmden and an outlet pipe tor the values 'opening through the wall of the pan above said, false bottom, substantially as described.
3. In a. centrifugal separator, the combination with an upright rotary cylinder, and an axial shaft support-ing the same, of an open-topped vpan disposed below the cylinder and having" a central upstanding sleeve surrounding the lower end of said siat, a false bottom within said pan producing a lower annular space around said sleeve, a
feed pipe communicating with this space, a
plurality of 'feed pipes rising from said space through this false bottom and extending upward into the cylinder, and an eX- haust pipe for the values communicating with the annular space around said sleeve and above said false bottom, substantially as described. l
ln testimony whereof l have hereunto set my hand in presence of two subscribing witnesses.
