UNITED STATES PATENT OFFICE JonN vAn FRITZ, or GEAUGA LAKE, OHIO.
CENTRIFUGAL SEIARATOR.
Application filed June 30, 1926. Serial N0. 119,671.
My invention relates to improvements in having mg my invention, whereby the fluid contents of the separator bowl is directed'in such manner as to contribute materially to the separation, deposit and retention of the heavier solid particles, in association with suitable straining or filtering means for effecting the removal of the lighter particles.
The features of my invention may best be explained in connection with the accompanying drawings illustrating a preferred embodiment of my improvements, wherein:
Figure 1 is a view inside elevation, also partially broken away and in section, to
show the featuresof my invention more clearly,
Figure 2 1s a transverse section on line 22, Fig. 1, and Figure '3 isan-enlarged' fragmentary sectional view of the filter construction. I
In each of the figures of these drawings I have employed the same character of reference to indicate identical parts.
The features ofthecentrifugal separator are sufficiently, shown in the View in elevation to enable one to understand the. construction and operation of the instant improvements, although certain details of general construction are omitted from this showing. j m ,f f
The bowl 0 is mountedfor' high-speed rotation upon theshaftb, steppedin the bottom of the casing 0 and driven by the'ge'ar' d and coacting threaded portion 6 provided:
upon theshaft. 'Above said bowl there is provided a supply pipe 6 fee-ding into the receptacle e and having a control valve 6 governing the flow of liquid from saidrecep tacle' into the bowl. 1
There is provided a central passage a within the bowl, through whichthe treated fluid is adapted to flow into the lower portion of the bowl and beneath the diaphragm perforations" f in two concentric rows and depending vanes f disposed in quartered arrangement beneath said diaphragm, approximating in shape the bottom configuration of said bowl. Above said diaphragm there are provided a series of frusto-conical members 9, g, g, which. are adjacentto the inner row of discharge-openings f in the diaphragm, the purpose of which will later be explained.
It will benoted that'the cover a of the bowl is spaced away from the tubular portiong of thecentral separator member to form an outlet from the bowl. Positioned thereon is the filter device, comprising, as better shown in Fig. 8, a fine wire screen it, which may be reinforced, if 'desired,iby a silk inner covering it, or one of filter paper, for filtering out-even finer particles than would be retained by the wire gauze.
Clamping members i, having wing nuts 2", are provided for securing the construction removably in assembled relation, as shown in Fig. 1, and the usual overflow and discharge spouts y", are laterally positioned and connected with the respective separator compartmentsfor withdrawing the fluid therefrom at different levels.
.I may now explain the operation of my" improved construction as employed inwtlie separation of suspended pigment materials, Q;-
for example, from mixed paint. The paint is discharged from pipe 6. into the receptacle 6, and valve 6 is adjusted to permit the regulated flow of the mixed paint in the central passage a and beneath diapl'iragm" f. vanesf' assistin imparting high centrifugal motion to the paint'within the bowl, and the continued flow of such paint causes it to rise through the perforations in the diaphragm The i with the heavier portions thereofinitially a,
following the course of the darts as indicated iii-Fig. loft-lie drawings.
Assuming that the centrifugal bowl is filled with the pigmentscharged paintysome of the heavier ngredients will be trapped below the diaphragm f and lodge circumferentially thereof intermediately of the vanes,
tending constantly to free the openings ,As the surcharged paint rises beneath the frusto-conicalmembers g, g, 9", these tend to deflect the heavier ingredients outwardly where they collect somewhat in successive strata under the ;influence of centrifugal lib force, thereby. constantly clearing the paint from its heavier and coarser ingredients which constantly seek the outer walls of the rotating bowl. This action is materially contributed to by the axially positioned members, having abrupt under faces and gradually inclined upper faces to cause the flow of the partially cleared paint substantially as indicated by the darts, while effecting eddy currents that successively tend to separate and trap the heavier materials therein.
The body of the paint as clarified by the successive action of the perforated diaphragm f and the frusto-conical members g, g, g, rises into the filter box 71; positioned at the top of the bowl. The separable easing 7c thereof is provided with spacing rings is which engage the wire screen it, somewhat diagrammatically shown in Fig. 3 upon a larger scale, and this ordinarily has associated therewith a fibrous filter medium h", of silk or the like, for the purpose of removing still liner solid ingredients fronr the paint. The filtered paint finds exit from the filter box through the openings 70 from which it is collected through the discharge spout j. It will be observed that an upper spout y' is provided merely for the overflow from the paint supply, either when it is excessive or after the bowl becomes charged with solid material and requires to be cleaned out.
The bowl in turn is readily opened by un screwing the clamping ring a whereupon the deflector members, the perforated diaphragm and vanes may be removed for. the purpose of clearing from the bowl the accumulated pigment material. The separated solid ingredients very much resemble putty in consistency. After the clamping ring a and cover a have been removed from the bowl, one operation will serve to lift out the center cones, together with the diaphragm and vanes in order to clear the bowl. These vanes subdivide the heavier sediment, so that it may readily be scraped out of the bottom of the bowl, while the removable parts are cleansed for resuming separation.
My improved separable filter affords a novel and advantageous construction in that the fine screen, gauze or other filtering materials are held away from the box by spacing rings of wire, thus affording free passage for the paint to escape after filtration.
As previously stated, this type of separator readily lends itself as well to the separation of varnish materials and other fluids surcharged with solids and partially dissolved materials that do not lend theselves readily to ordinary separator treatment. Its construction lends itself to easily cleaning, not only the bowl, the deflector members, but the associated filter device, as well.
Having now shown and described the preferred embodiment of my invention, I claim as new and desire to secure by Letters Patent, together with such n'iodifications there of as may be made by those ordinarily skilled in the art, the following:
1. A centrifugal separator equipped with a central supply feed beneath a perforated diaphragn'i substantially closing the lower portion of the bowl, and a superposed axial deflecting member.
2. A centrifugal separator equipped with a central supply feed beneath a perforated diaphragm and a superposed frusto-conical deflecting member adjacent to the perforations.
3. A centrifugal separator equipped with a central supply feed associated with a central deflecting member having abrupt lower faces and inclined upper faces.
a. A centrifugal separator equipped with a central supply feed, a perforated diaphragm, and a superposed series of upwardly inclined frusto-conical deflecting members positioned in the line of discharge of the perforated diaphragm.
5. A centrifugal separator equipped with a central supply feed to the bottom of the bowl, a perforated diaphragm substantially closing the lower portion of said bowl, and a central deflecting member having abrupt lower faces and gradually inclined upper faces.
6. A centrifugal separator equipped with a central supply feed, a centrally perforated diaphragm substantially closing the lower portion of the separator bowl, vanes thereon for impelling the fluid and deflecting means positioned adjacent to the axis of the bowl in the line of discharge from the perforations.
7. A centrifugal separator equipped with an axial supply feed beneath a centrally perforated diaphragm substantially closing the lower portion of the separator chamber, and an axially positioned deflecting member above said perforations provided with abrupt lower faces and tapering upper faces.
In testimony whereof I do nowaffix my signature. I
