My invention relates materials, such as sand containing watenor other mixed uid materials, and has among its objects and advantages the provision of"r an .improved More specifically, I providefaf rotating shell having a central opening at its top lfor the introduction of. materials to be separated, The shell is provided with a central opening at its bottom through which separated or: processed material is discharged. The rotating shell isdivided 'horis (ci. asa-z) to the separationfofiluid `I2. Both sections `are provided withilanges 20,
about their larger ends and between which is zontally. as by a diskv xedly related to the shell,
to divide the latterinto at least two chambers y or zones interconnected by a throat at Atheperimeterofthedisk. f j' In one chamber an overbalancing initial centrifugal pressure is generated to-iorce the materials through the machine where it will assume orbits oi rotation natural to their respective lgrav. ity characteristics. Each of these orbits is sepa-` deliveries by an excess of initial centrifugal pressure.
as additional material is supplied to the inlet of the machine, so that iiow ofmaterial will occur only when pressure above the dividing wall exceels the opposing pressure beneath the dividing arranged a screen 22.1 .The lscreen andthe two "ilanges are secured into aimitary structure bybolts 24.
is mounted onfa hollow base V2S havinga tubularupstandingpost 28. This post is provided with a iiange SIIv upon which is supported an outer bearing race 22.- /A driveshaft 24 extendsjloosely through the-.flange l0, and is 2li rately forced through the machine to separate,
The initial excess pressure is established only 'provided with an inner bearing race '38 kfixed thereto and coacting with the outer bearin'g'ra'ce l2 through the medium of angular thrust rollers Il.
' To the upper end of theshaft 34 is fixedly connected ahead 40 to which lare welded four depending and vertically arrangedwebs 42 posi- 'livery at the axis or the disk. The sneu is shaped with a bulge having its greater diameter lying in the, plane of the disk and provided with a screen about its area of greater diameter for the passage of fluid rejects.

Figure 4`is a sectional view along the line 4-4 r of Figure l. and i Figure 5 is an enlarged vertical sectional view through the screen at the point of largest diameter of the shell.
/In the embodiment of the invention selected for illustration, I make use of a shell or bowl Il comprising a top section I2 and a bottom sec tioned radially with respect to theshaft 34. 'Ifhehead 40 is keyed at 44 to the shaft I4, and the lower ends of thewebs 42 are welded to a horizontal disk 43 lying in the plane of the screen 22 and 'dividing the shell III intochambers 48 and il having communication through the medium of an annular throat 52 lying between the perimeter of the disk 4i and the screen 22.
Webs I4 are bolted at 58 to thedisk 48 and at I8 to an annular flange 00 depending lfrom the disk 4l and -constituting an opening in the disk located centrally thereof and coaxially with Athepost 28. While the webs`42 have their outer edges l2 spaced from and generally conforming to the wail of the section I2, the webs I4 have edges B4 lying against the inner .face of the section I4, but having contact therewith only through limited intermediate areas or the section.
Abearing 88 is provided at the lower end of thebase 28 for supporting the shaft I4. 'I'his shaft is provided with abevel gear 68 meshing with a bevel `gear 'IU attached to a shaft 'I2 drivgn by a motor 14. A bearing 1B supports theshaft 12 adjacent thegear 10. a
A screen guard and collector bowl 'I8 enclosesv the greater part of the shell I0 but is spaced therefrom` to provide an annular passage extending downwardly and communicating with an annular `neclr` t2 located beneath the lower end oi Vthe section I4. Material flowing downwardly in the' passage 80 and through the neck 82 may be withdrawn through the medium of aconduit 84. Thebowl 18 is stationary and includes abottom 86 resting on thebase 26 and anannular flange 88 extending upwardly but loosely about'thelower end of theilange 60. Materials flowing downwardly through theflange 60 are received in atrough 90 extending about thepost 28 and provided with an outlet conduit 92 leading into the neck 82. The trough is fixed to theflange 88 and closely embracesthepost 28.
Arranged concentrically with and inside the neck 82 is an annularflange 84 extending a short distance above the lower end-of the section |4 and exteriorly thereof. This iange extends upwardly from the`bottom 88 and coacts with theflange 88 to provide an annular trough 06 into which material flows from the section i4. Thetrough 90 is separate from thetroughSB-and the latter is separate from the neck 82. 'Afnoutlet 98 is provided for thetrough 98. g
A valve controlled material feeding pipe |00 is arranged above the shell I0, the pipe having a delivery end |02 extending a, short distance inside the section I2 and .to one side of its axis.A
The screen 22 comprises dat rings |04 of the same diameter as theilanges 20. Washers |06 v,are mounted on thebolts 24 and positioned between the rings |04 to space the rings one from the other. The inner faces oi' the rings are provided with anges |08 which terminate flush with the inside edge .faces of the rings. The flange |08 on each ring is spaced a predetermined distance from the at face of an adjacent ring, the spacing being determined by the thickness of the washers |06, which washers may be changed for other washers of different thicknesses to vary the said post, a bearing supported on said ilange, a
drive shaft journalled in said bearing, a head keyedtothe upper end of said shaft, a plurality oi depending and vertically arranged webs selcured to said head radially of said shaft, said wall spacing between the anges |08 and the cooperi ating rings, depending upon the nature of the material to be screened therethrough.
My invention embodies a pressure and separating zone, a sealing throat below the separating zone, and a counterbalanclng pressure zone beneath the throat, where the now is opposed and stopped at the point of a minimum safe sealing condition, until the addition of heavy material, displacing lighter material in the separating zone, builds up a greater centrifugal pressure to overcome the opposing pressure, thus moving the seal and discharging the excess above balanced requirements.
The material introduced into the shell i0 builds up in the nature of a wall against the shell so that liquids and the like may spill down through theflange 60. The screen 22 vents entralned fluids from the heavier material. The separated material is isolated from the lighter materials. The lighter materials are evacuated from thetrough 90 and the neck 82 by gravity, and the separated or processed material from thetrough 96 is preferably evacuated by air suction.
Without further elaboration, the foregoing will so fully explain my invention, that others may, by applying current knowledge, readilyadapt the same for use under various conditions of service.
