. CENTRIFUGAL FIXTURE.

Application filed May 4,

In all the processesof evaporation and distillation, and throughout the arts of fluid purification and rectification, as by separators, it is both assumed and desired that `the fluid evolved or treated shall leave'the ed as to induce a strong centrifugal ac tion Within the escamg or discharged fluid to the Y end that the foreign substances and heavier constituents are effectually and certairly removed Cfrom outgoing or escaping Huid. The aforesaid vforeign substances or heavier constituents are suitably discharged from the devices externally thereof.

The invention has among other objects to perfect and refine the details of devices for carrying out processes of purification, and in theV simplest and most reliablev manner for A the performance of the process. With these and other objects in view, the specific character of the invention will be more readily understood by reference to the accompanying drawings which form a part of this specification, and in which: i Y Fig.- 1 is a longitudinal vertical section of one form of centrifugal fixture embodying this invention. f

f F v The present inventlon, which embraces certain structural features which are con- `Cerned with features heretofore referred to,

embraces tuyeres, that is, rotation inducing members, which may be of a number of different constructions but are generally typified by the member 8 herein illustrated.

Said member 8, as herein shown, is comi posed of a top ring 8a, a plurality of tangentially positioned tuyre blades 8b, and an imperforate bottom plate or disc 8. The inner edges ofthe blades substantially conform to or meet an imaginary cylinder indicated by the circle 8d, Fig. 2, and this'is true also of the inner periphery of the top ring 8*. The tuyre blades being tangential -to the aforesaid imaginary cylinder, present tangential impact surfaces to the incoming fluid. While other forms and arrangements of tuyre blades than those illustrated by wayK of example only, may 'be employed, vin

any case the blades form long and relatively thin slots or tuyre openings 9. and hence collectively subdivide the iuid into a plurality of thin streams that substantially parallel the axis of the tuyre ring. .The vapor or other fluid approaching'the fixture impacts the surfaces of the tuyre blades, and is directed by'such surfaces into the described relatively -thin streams. These sov i streams enter the substantially cylindrical tuyre ring tangentially and, encountering the annular arrangement of blades, combine to set up a very rapid'whirling action withopenngs the streams of fluid impact the inner surface of the tuyre blades. These surfaces being preferably tangential in position, conform to the normal angle of incidence of globules of liquid or particles carried by 1in the tuyre ring. O n'entering the tuyre the streams of fluid. These globules instead f of being swept away are left or retained upon the inner surfaces ofthe tuyere blades. The accumulationof such impurities isproportionate tothe quantity thereof present in the Huid passing through the fixture, and,

as the deposit takes on the general whirling action ofthe body or iiuid Within the tuy're ring, that very whirling'action insures the retention of the accumulated substances at vthe lperiphery of the whirling body, that is,

on theinner periphery of the tuyre ring. Followin the general movement of the whirling ody within the tuyere ring, the purified liquid or gas moves axially towards the outlet 10. The upward sweeping action lifts the deposit of impurities to the top'of the tu re ring and into the race-member 14.

The tuyre ring member 8, the component4 parts Sof which have been heretofore described, is mounted in a chamber of cast metal, which in .the construction shown in Fi 1 has flanges 18, 19, at its opposite en s, through which coupling( connections are made with the inlet andoutlet pipes, 7, 10," which, are, respectivel provided with coupling flanges 7, `10,t e flanges of the casing being, if desired, connected lwith said couplmg flanges by bolts 21, whose ends are threaded to receive nuts 22. The race-way 14 is herein shown as formed in the casing 16 and the .latter is cast around the ring 8a ofthe so-called tuyre member 8. This provides avery convenient and rigid construction, and `wherein the tuy're member is reliably and permanently secured in integral manner to the interior of the casing, within which latter said tuyre member is thus sus'- pended with suliicient space surrounding the tyure blades and the bottom 8. Inthe modification shown in Figs. et and 5 the tuyre member 8 is provided with a bottom 8c of suiiicient thickness to cooperate at its circumferential edge with inwardly rojectin radial lugs 8f, Vthe latter being ormed uring the process of casting the casing around the tu re member 8 so as to engage and'support t ie latter in proper position within said casing.y In th1s ,construction, also, the walls of @the casing are in the casting operation formld with an inwardly projectingv annular portion'25 ywhich surrounds and embraces the lower extremity of the tuyre rin so that the latter is held or `suspended wit in the casing 16 by the lugs 8f and the annular rib or projection 25. In th1s particular construction the pipes 7, and 10, which, respectively, convey the fluid into and discharge it` from the casing 16, are

Athreaded into the latter.

In the modification illustrated in Fig. 6, the tuyre member '8 is provided with a bottom 8c, tuyre blades 8", and an upper' ring 8a, which latter is cast within the casing 16, as described in connection with Fig. 1.. Under this construction I have shown an adjustable inner wall'or bottom member 30, which is swiveled to a screw stem 31, in threaded engagement with a hole in the 'within said casing in the bottom' 8, said stem having preferably a polygonal end 32 "for engagement by av wrench or other tool. The adjustable bottom 30 is herein shownl as provided with a" cone-member 35,l an,d is confined to the stem y 31 between ahead 364 on the latter, and a washer 37. When thes'tem is turned the 'y bottom may be moved to adjust suitablyl the area of` the openings through the tuyre rin I'the construction illustrated in Fig. 7, the' tuyre member 8 is cast with the inwardly projecting lugs 8t for engagement with the bottom 8? and with the .inwardly projectingl cast annulus or rib 25 for engagement wit the op osite end portion of the `tuyre ring, where y the latter is cast within and held flrml by the casing 16 in the same manner as eretofore Adescribed with reference to Fig. 4. In the constructionment of thearea. of. the tuyre openings is effected from' the inside of the casmg 16 in a.- construction wherein the tuv re lrin is held l 'or sustained within the casing byt ei expering, s that said ring becomes in effect an integral structure with the casing.

Claims: l v 'i 1. A centrifugal fluid purifying device, comprising, in combination, a casing, a hollow'ring member thereiny and an internally smaller coaxial tuyre ring portion secured I process/of casting the casing, and adapted to whirlinglyfd'irect the fluid into andl through said member, said hollow member having a still smaller central outlet axially remote from said tuyre portion and also having a peripheraldischarge nozzle.

2. centr1fugal llu1d purifymg dev1ce, comprising, 1n comb1nat1on, a c1rcumferential series of tangential tuyere blades, a `ring-y -dient.of casting the latter about the tuyre at one end of said blades, and a casing cast about said blades and ring, sidring being embedded in the metal of said casing during the recess of casting, and a hollow ring member in said casing of larger diameter than the diameter of said tuyres, and provided with a tangential outlet. w

3. A centrifugal fluid purifying device, comprisingfin combination, a circumferential series of tangential tuyre bla-des, a bottom member at one endyof said blades, a ring member at the'other end thereof, an external `enclosing casing for saidblades -and rings which is cast'around said ring` and permanently embraces it, and an adjustable plate located Within said tuyres and movable by means accessible from within the casing to vary the area of the tuyre openings.

4. A centrifugal Huid purifyin device,

' comprising, in combination, a cir'cu ar series tuyre blades and cast about said blades so as to secure them permanently in position 10 therein, and a hollow ring member in said casing having a tangential discharge opening.

In testimony whereof I have hereunto set my hand this 30th -day of April, A. D. 1925.
