GENTRIFUGAL YROCESS OF SEPARATION.

vsubject of the .UNITnn snuriaeI .JAVIER RESINES,
To all whom 'it may concern i A Be it known that l, Jaume llnsrnne, a King of Spain, resident oi? Madrid, Spain, have invented a new and useful Improvement in Centrifugal lrocees of Se eration, of which the following o epeoilibation.
The object of my invention is to provide a centrifugal process for separating solids heldin suspension in. liquids, cleaning the latter by causing the liquid to follow. a lengthened course proportionate to the size of the apparatus employed.
To attain this object my invention consists of an improved centrifugal process wherein the course of the liquid is alter nately deflected and sinuously directed while the liquid is subjected to the action or' the centrifugal force, thus obtaining a lengt-honed course and consequently an increase of the time of said centrifugal action, as Well 'as an augmentation et the radius ci the overilow that produces the corresponding considerable increase oit the actual actin centrifugal force.
lt further consiste of such process iu which counter-currents against the separat ing force are created which aid in separating the solids from the liquids.
It further consists ot' such procese in which the course of the liquid is alternately deliected to create counter-currents against the separating torce, whereupon, the liquid is finally filtered by means of and in the natural ydirection of the centrifugal force.
It further consists of suclrprocess and apparatus in which the course of the liquid is deflected to create counter-currents against'theseparating force, whereupon the `liquid is rpassed throuoh a filter utilizing the di erence-in the leve s of the liquid in the chambers, 4thus making the liquid overflow toward the center of rotation, while the solids are thrown by the centrifugal force in an opposite direction toward'the side Wall.I
It further consists of such process in `which the body of liquid to be separated is contained in a rotating container and in maintaining the inner side of the liquid accessible to the surrounding atmosphere.
It further consists of other novel features of operation, all as will be hereinafter fully ,set forth.
For the purpose of illustrating my invention ,I have shown in the accompanying Specilcation et Lettere Patent. Application lcd .May 3.92.1;

found in practice to give satisfactory ann` reliable results although it is to stood that the various' which my invention consists can be vuriously arranged and organized and that my invention is not limited to 'the precise arrangement and organization oi' these instrumentalities as herein shown and described.

Referring to the drawings, the numeralsi. indicates the cylinder or body' oit a centrifunel separator, suitably mounted to be revolved around its vertical axis and haviuug,r en annular top 5.. This; cylinder is surrounded by a suitable jacket, 2, having an outlet, 3, at .its bottom for the puriticd liquid. A ieedpipe, 7, extends to near the bottom of the eylii'uieul Where it has an op and serves to convey the lit o t' arated into the cylinder. l plates, 9 and i0, am I der, the plate 'Sl being s. toe wall of the same and the ,platos .i w supported to leave an annular space between their outer edges and the Wall oi the cylinder and being' arranged to alternate with thc plate A cylindrical iiltering wail, il, sur ported between the inner edge ot the tippen most plate l0 and the top, 5, o the cylinder, and may be formed from any sui 1"; or desired material permeable to liquid, auch as tine Wire-gauze, felt, or other straining or filtering material.
In the device illustrated in Fig. Q, the upperportion, 13, of the wall of the cylinder forms the Elton/bei., 5 tornino from any niaterial permeable to liquid and capable or" retaining the solide to be separated in .lthe device illustrated in Fig. i, the staggered baille-plates are dispensed with, l there heine; only line annular plate, le,
which divides the cylinder 5in a v.irefer tuur.'
same have beer be undo;l t instrumentalilies of titi pertinent having an impermeable wall and an upper compartment having the permeable wall 11.
In the device illustrated in Fig. 4, the
cylinder has no annular plates and its entire wall is permeable. In the devices illustrated in Figs. 2, 3 and Il, an annular trough, 4, is provided near the top of the jacket and below the annular top of the cylinder, and an outlet, 6, is provided froln said trouelh.r
When the cylinder is rapidly revolved and whatever liquid to be purified is fed into it through the feed pipe, the centrifugal force will throw the liquid against the wall of the cylinder and the heavier solids will strike the wall and be deposited there, while the purified liquid will ascend and iiow out through the liltcr fand overflow the top of the cylinder, being received in the jacket of the separator from which it flows out through the outlet at' the bottom. As the liquid ascends, the baille-plaies will force it to take a sinuous or tortuou'liow, whereby the current, as it passes to and around the inner edge of the annular plate upon the wall', will be forced against the centrifugal force, as indicated by the arrows in Fig. l. By creating there counter-currents. the solid particles suspended in the liquid will be 're. deposited, while 4the liquid "asf tarded and eends and flows out through the lilter, where the 4last solids will be caught.
It will thus bc seen that the course of the liquid through the separator will be. long compared with the height of the cylinder of the same and will be in the form of an annular or hollow cylindrical body on account of the action of the centrifugal force, and
thatthe long, deflected and tortuous course` of the liquid will expose the solids held in suspension in the liquid to the centrifugal force for longer time than when the flow of the liquid is straight and unimpeded. It will also be understood that 'oy feeding the liquid at the bottom of the separator and directing it upward in its tortuous course, the force of gravity exerts a rctarding inluence upon the liquid, thus exposing` the latter to the action of centrifugal forceI for a comparatively long` space ol time and also causing the solids to precipitato by gravity. The ow of the liquid is opposed by the natural forcesf-gravity and centrifugal force,wl1ereby thorough separation is attained. This impcding of the course of the liquid and of the solidsv therein suspended,
rovides a more perfect separation and purigca'tion than ispossiblc where the liquid is thrown directly against the wall of a separator. When the feed of the liquid is so rapid in the forms of the'dcvice illustrated in Figs. 2, 3 and @that the filter cannot admit of the discharge of all of the liquid, the latter will overflow the top of the cylinder' and will be .ratus, such flow being forced to caught in the trough. If the overflowing will flow against the sepa-rating force and the solids still in suspension will be arrested and thrown out against the impermeable wall of the cylinder.
Vthe top-chamber of the cylinder, the liquid In the form of separator illustrated in 'i Fig. 3, the retardation of vthe liquid is less than in the form illustrated in Figs. l and 2, owing to this form only having one bailleplate, and in the form illustratedvinF ig. 4,
no retardation of the liquid takes place, but
the, three latter forms have trough or gutter for the `As the liquid having the solids in sion ascends inthe cylinder, ticle will not only the annular Suspentravel upward until it is forced against the wall of the cylinder, but4 will also travel around with the liquid and overflow liquid.
each solid parf the rotating cylinder and baille-plates. ,.The
molecules of the clear liquid willV also travel around and upward, but, being lighter and easier movable than the solid molecules, the l liquid will pass quicker upward around the' baffle-plates than the solids which will grad.
ually work outward and settle `upon the walls of the cylinder. The solid molecules' will thus describe a tle there, thus traveling a comparatively long distance through the separator toadlnit of' thecentrifugal force acting'v upon all of the solid particles in the liquid to be separated and accomplishing a thorough cleaning or separation. As the battle-plates direct the fiowo'f the molecules alternately with and molecules will. describe helicoidal lines of alternately increasing and decreasing radii, thus exposing the heavier solid molecules to the action of the centrifugal force for a comparative long space of time.
