- from the drilling fluid, all particles of granulated formations thatis possible. 'I'his is also necessa.ry tor the proper maintenance cf the mud pumps und tubular equlpment, through which the mud has to be handled Irom the pumps to the bit at the bottom of the well-bore.
One object of this invention is to aflord an apparatus for the efliclent separation of these granulated formations from the drilling fluid and wherein the reticulated sections of the screening assembly are held wedged in place without the use of bolts und nuts.
Another object of the invention ls to afl'ord equipment for this purpose that is selt-governlng in its speed 01 operation.
Another object of this invention 1s to aflord an apparatus for this purpose, the power Ior operatlon of which is suppl1ed largely by the mass und velocity of the fluld handled.
A 1urther object 013 this invention ls to afiord equipment o1 sturdy construction, und having replaceable parts, which are easily and cheaply replaced.
W1th these and other objects in view & S will be obvious Irom the description to fqllow, I here sei; 1'orth one and a preterred Iorm o! this invention, as shown in the dra.wing herewith attached, in which Figure 1 shows a, side elevation 01 the appara.tus, and
Figure 2 shows an end elevatlon on the discharge end o! the apparatus, and
Flgure 3 shows a detailed construction 013 the screen sections, as fastened to the ma.ln body o1 the machine, and
Flgure .4 shows a side elevation of one o1 said screen sections.
Beten-Ing more particularly to the drawhig, in which similar numbers represent slmilar parts in all flgures, the invention consists of the runners I joined together by the cross-members II. Supported on these cross-members by vertlcal members I2 and I3, are the muss-members I5, on which are stationed the journal boxes I4, in which ls rotata'.bly mounted the malu shatt I8.
Mounted on the main shaft I8 ls the hub I9, which has the radially extending webs 20. The outer edges of said radial webs are formed into a.
Y section 2l, having lnwardly turned lips 22, Ior receiving the screen sections 23, which have the hook-type edges 24, which fit over the lips 22. It will be noted that assembly of a number o1 the screen sectlons, with the hub and radially extending arms, form a multi-sided cylinder shown ..to be in this ca.se a chrom'cally-shaped hexagon. 10"
Mounted upon one end of the shaft 18 is the sprocket 40, which is fixed stationary thereto.
Supported on the upstanding members 25, which are mounted upon the cross-members II, is the drive shaft 21, which is rotatably mounted in the journals 4l. Rigidly fixed on one end of the drive shaft 21, is the sprocket 38, which 1s rotatably fixed to the sprocket 40 on shaft II, by means of the sprocket chain 29. Flxedly mounted on the other end of the sha.ft 21, is the 20 bevel gear 42, which meshes with the bevel gear '31, fixedly mounted upon the jackshaft 86.
Fixedly mounted upon the other end of the juckshaft 36, 1s the bevel gear 35, which in turn meshes with the bevel gear 34, which is rlgidly mounted an the shaft 32. Keyed to the shaft 32, is the undershot wheel 3l, which operates in.the fluid chute 30, through which the fluid ls transmitted to the mud screen. The lower end of the shaft I8 is journaled in the bearing, which in turn is supported by the member I 5, hinged to the subframe structure by the hinge I8. The other end of this member I5, is arranged to rest upon the cam wheel 43, which 1s rigidly mounted on shaft 21.
In operation, the drilling fluid is transported to the mud screen.through the ahnte 30, which it will be noted, extends into one side o1 the cylindrlcal portion of the mud screen. The energy In the moving fluld passing through and around the undershot wheel 3l, transmits its energy 01. motion to said wheel. The radially extending webs 20 form an overshot water turbine wheel, to which the energy of the incoming fluid also transmits energy for rotating the screen cylinder. 'I'his rotative motion transxnitted to both the radially extending webs and the undershot wheel 3l, are added through the bevel gears 34 and 35, the shaft 36, the bevel gears 31 and 42, the shaft 21. the sprockets 38 and 40, and the sprocket cha.ln 29, to insure rotatlon of the screen, for the purpose 015 dlscharging the solids which a.re lefl; in'- side the cylinder screen, alter the fluld passes through the screen sectlons.
At the same tlme, the undershot wheel 81 tends u to govern the speed rotatlon 01 the screen cyllnder to that speed made posslble through the beveled gear andsprocket wheel ratlos, thus lnsuring the proper amount 01 screen suriace 1'or the screenlng of a proportionate amount o! the liquid. 'Ihere 13 a natura] tendency for the sol1ds iwhleh are lett in the screen to cllng to the screen surtaces. 'Ihe cooperatlon by the lower member I8, upon wh1ch 1s dc'aumaled the lower end 01 the shaft I8 und the cam wheel transmlts to the screen cylinder. a vlbratory motlon during the rotat1on o! the shaft 21, which tends to dlslodge any 01 the solld partlcles wh1ch might cling to the screen sur1'aces am! In that way discharge the solld partlcles trom the lower end 01 the screen cylinder.
The screen sections 23 are tormed in a. wedge shape, belng narrower at one end than at the other. Thls constructlon allows the wedglng o! these screen sections onto the radlally extendlng webs 2ll, ellmlnatlng the necesslty 01 other means o! attachment, andallowing take-up, in case of y the screen expansion durlng operations.
It ls obvlous that slight changes can be made in the constructlon o! the inventlon, without departlng from the splt et the lnvention, and w1th these in mlnd;
What I clalm is:-
1. A shale separator comprlslng a support, an
the energy o! movlng materlal in seid last-named means end havlng connectlon with the flutnamed means for effecting rotatlon to sald screen.
2. A shale separater comprlslng a support, an lnclined open ended rotatable screen havlng a radlally webbed center end screen sectlons irrterfltted therewith to provlde a multlslded cylinder for recelvlng unflltered. materia1 a.t the hlgher end thereof and diseharging certain o! the materlal through the screen seetlons and the re-- mainder 01 seid materlal.through the lowermost open end, rotatable means in the support carry- Ing said cyllnder meaus for supplylng unfiltered materlal to the screen above lts axis o! rotatlon through the higher end thereof, means drlven by the energy o! movlngmaterial in sa1d lastnamed means and havln'g connectlon wlth the flrst-named means for eflecting rotatlon to sald screen, und vibrators associated wlth the support and sa1d first-named means am! actuated by the last-named means.
3. A shale separator comprising a rotatable screen, means holding the screen In an lnclined posltion, arotatable power wheel for operatlon by the energy of moving matter being screened,
shaft und gear connections between the power wheel and the said screen for the transter 01 power to the latter, hinged vertlcally swinglng supports carrled by the screen holdi ng means and active upon the latter for vibration thereot, cams .operated by seid shaft and gear connections 1'or activity upon the hinged supports and imparting vibratory action thereto, the sald screen being connected and arranged to discharge the most solid matter through lts lowermost end, and means accommodating the power wheel and supplying liquid to the interior of the screen remote from the discharge end thereof and at a point above and at one side o! its axls.
