Description

y 1960 c. M. TURSKY FLUID SEPARATORS Filed July 16. 1958 INVENTOR. CHARLES M. TURSKY ATTORNEY United This invention relates to devices for use in separating particles from fluids or separating a fluid in one consistency from a lighter fluid in what may be termed a filtering operation. More particularly, the invention deals with a device of the character described employing a cylinder having a mountable head at one end with a multiplicity of coils supported in the cylinder, the head having means for admitting and discharging fluid with respect to the cylinder and a single bolt or other coupling means for detachably supporting the cylinder in connection with the head; thereby facilitating cleaning of the separator or filter elements from time to time without displacing the head from a suitable support.

. The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain ,embodiments of the invention are disclosed and, in which, theseparate parts are designated by suitable reference characters in each of the views and, in which:

My invention relates primarily to separators for use in conjunction with apparatus, mechanisms of various types and kind for the purpose of separating undesirable particles or foreign elements from fluids to be supplied to the apparatus, or in separating heavy fluids from lighter fluids rates Faten't O in order to transmit and feed to the apparatus the desired end fluid product for successive and proper functioning of the apparatus.

. By way of giving some illustrations, the device can b utilized as a separator in the supply of oil to various hydraulically operated devices or apparatus, for the passage of lubricating oils to various machines or apparatus, including motors, the separation or filtering of fuel supplied to an engine or other power medium, the separation of foreign particles from water systems of various types and kinds and many other uses which will be apparent to those skilled in the art.

The invention, as illustrated in the accompanying drawing, employs a relatively small cylinder or casing .10, preferably having a downwardly contracted or tapered bore 11 extending to a contractedlower end 12 having anaperture 13 therein. At 14 is shown a head in the form of a ring-like cap, having extended flanges 15 in any suitable arrangement for adaptation to a predetermined support, the flanges being apertured, as seen at 16, for reception of fastening devices to secure the head to such support.

Thehead 14 has a central bore 17, smaller in diameter than thebore 13 so as to accommodate along coupling bolt 18, having a small diameterupper end 19 and a larger diameterlower end 20, these diameters intersecting at theline 21 and thesmaller diameter end 19 joins thend 20 in an outwardly flaredwall portion 22.

The bore 17 is arranged adjacent the upper end of thehead 14 and this bore communicates with a larger diameter bore 23, which opens into a large annular recess or 2,945,445 Patented July 26, 1960chamber 24 in the lower surface of thehead 14. In therecess 24 is fitted snugly, but freely, the upper flange end 25 of adisc 26 and this flanged end is sealed upon the upper end of thecylinder 10 by an O-ring or the like, as indicated at 27.

Thedisc 26 has a multiplicity ofsmall diameter apertures 28 which open into a furtherannular recess 29 on the bottom wall of therecess 24 and slightlylarger diameter apertures 30, in which upper ends of a multiplicity of separator orfilter coils 31 are cemented or otherwise secured.

It will also be apparent that the disc proper fits snugly in the upper end of thecylinder 10. It will further appear that thedisc 26 has, centrally thereof, abore 32, which registers with the bore 23 of thehead 14. At this time, it is also well to note that the line of division at 21 on thebolt 18 is positioned adjacent but below the lower end of thedisc 26, so that fluid introduced into the separator will be directed by thecurved surface 22 radially and laterally into thecylinder 10, this fluid being introduced through anintake pipe 33 coupled with one side of the head and opening into aport 34, which registers with the bore 23. At the opposed side of thehead 14 is 'adischarge pipe 35, registering with an L-shaped bore orpassage 36 which, in turn, communicates with theannular recess 29.

Thebolt 18 has anintegral head 37 at its lower end with anut 38,washer 39 and O-ring 40 at its opposed end, thus providing the clamping action of the entire assemblage and it is preferred that agasket 41 be positioned between thehead 37 and the lower end of the cylinder. The lower end of the bolt has a large threadedbore 42 for reception of a petcock or other type ofvalve 43, controlling drainage discharge, thebore 42 communicating with asmall diameter bore 44, having aradial branch 45 opening into the lower contracted end of thecylinder 10 for discharge of sediment or the like collected in this lower contracted end.

Considering Fig. 2 of the drawing, it will appear that thecoils 31 are arranged snugly with respect to each other in the cylinder orcasing 10, but still providepassages 46 therearound, so that fluid introduced into the cylinder will have access to the periphery of all of thecoils 31 and the fluid, with the foreign particles or the like separated therefrom, will pass into thebore 47 of the coils and, thus, into theapertures 28, therecess 29, the

However, in some instances, where extensiveseparation or filtration is desired, the fluid discharged from .one.

pear that the lower end of each of thecoils 31, or the:

bore 47 therein, is sealed by a plug having a rounded.

head end 48 and apin end 49 fitted snugly in the coils;

In some instances, the attachment of the plugmay be by. way of :a suitable cement, particularly as and whenhigh pressures are used in passage of fluids into and through the coils. It will be noted, from a consideration of Fig. 'l of the drawing, that some of thecoils extenddeeper into thecylinder 10 than others and these are-- The showing in Fig-r 1- indicated at 31 in said figure. is. simply diagrammatic and, if desired, every other coilin each of the circumferential rows of coils, as noted in Fig. 2, can be one of the longercoils.

The coils are made in accordance with the teachings in myprior Patent Number 2,7 61,5 66,, granted September;

4, 1956, in other words, in the present showing, the angularity in the windings illustrated at 58 and the flats will appear, as at 51, in the diagrammatic showing of Pig. 5 and, by control of the windings and the flats, the degree of separation in the coils can be regulated to extremely fine areas suilicient to separate one fluid from a heavier fluid and, further, in control of the separation of particles, particularly as to size when the device is used primarily as a separator.

At this time, it is also well to bear in mind that, by using the multiple pass idea in a series of the separators, a control can be had for grading the size of the particles separated in each of the several passes, the larger panticles being first removed and then grading down to the minutest of particles. This latter method of procedure would be desirable as and when the retrieving of the different size particles would be advantageous for secondary uses, particularly where the particles separated would con- .stitute usage end products.

It is believed that the function and operation of my improved separator or filter will be apparent from a consideration of the foregoing description but, briefly, it may be stated that the incoming fluid introduced under a predetermined pressure through thepipe 33 is first flared radially into the upper end of the cylinder and through the coils at the upper end of the cylinder at theposition 21 on thebolt 13. Some of the fluid also passes downwardly into the cylinder at the inner ends of the coils. A separated fluid passes into thebores 47 of the coil, then out through thedischarge pipe 35 through the path previously set forth, particles, sediment or the like removed by the multiplicity of coils will drop into the lower contracted end of thecylinder 16 and may be periodically discharged by opening of .thevalve 43. This can be a pressure discharge, in some instances, with the pressure applied by the incoming fluid.

Itis also apparent that, periodically, in some instances, the passes of flow can be reversed and a suitable cleaning fluid introduced into thepipe 35 to clear the coils, facilitating discharge of any foreign matter, particles or the like that may collect upon the surfaces of the coils. In this last operation, suitable means will be provided to close the passes in thepipe 33 so that the discharge will be through the lower end of the casing and thevalve 43.

As and when desired, thebolt 18 can be removed, thecasing 10 dropped from thehead 14 and the filter unit, comprising thedisc 26, with thecoils 31 fixed thereto, can be removed from thecasing 10 and washed or otherwise cleaned for freeing all of the passages in the coils and, then, the parts can be re-assembled quickly and easily for a continued use of the separator or filter.

The various materials employed in the complete separator will depend entirely upon the uses to which the separator is applied. However, in most uses, the wire of thecoils 31 will be made from stainless steel and highly finished, so as to provide free unobstructed passage of the fluid through the coils and to minimize collection of foreign matter on the coils.

By employing the tapered bore 11 in the cylinder or casing, the lower ends of the coils are urged or crammed inwardly to a slight extent, thus reducing spacing between the coils at the lower end portions thereof. For purposes of description, theport 34 andpassage 36 may be referred to as intake and discharge passages, the intake communicating with the bore 23 of the head; whereas, the discharge communicates with theannular recess 29.

It will be apparent that in cramming lower ends of the coils by virtue of the taper of the casing, the lower ends of the coils are brought into closer proximity to each other than where the coils are attached to thedisc 26. This structural feature aids in retarding the larger particles or foreign elements which, in many instances, may actually collect in and be retained in thepassages 46 between the coils and be displaced as and when the filter element is .removed from the casing and the head. In this connection, it must be borne in mind that coils, when the unit is free, are held only in thedisc 26. The remainder of the coils are free for agitation or shaking in displacing particles during a washing or cleaning operation.

it may be well to point out, by way of illustration, that, in a cylinder where the bore 11 is approximately 1% in diameter at its lower end portion, fifty odd coils can be arranged in the casing around the bolt ormember 18, the coils being substantially 3" in length and, with approximately fifty windings per inch, with approximately twelve controlled filter passages between adjacent windings, it will be apparent that, in a relatively small unit of the type and kind under consideration anywhere from 300,000 to 500,000 filter passages can be provided at any degree .of filtration which may be desired, here keeping in mind that, when several passes of fluid are made through a plurality of separators, the degree of opening in the filter passages will be varied.

Where water or condensation prevails in a liquid, it will be apparent that a filter of the type and kind disclosed will separate the water from the liquid in passage through the separator and this can be periodically drained through the drainage means provided. In this sense, the condensation or water is one of the numerous undesirable particles of foreign elements which can prevail in light and heavy oils and gases, as well as in other chemicals.
