Claims.
This invention relates to disks for centrifugal separators and more particularly for use in cream separators.
An object of the invention is to simplify the construction of such disks with a view to decreasing the cost thereof and, at the same time, providing a construction which will well withstand the pressure necessarily applied thereto as a. series of disks is assembled in the bowl of the separator.
Another object is to provide disks which, when assembled in the bowl, provide no insanitary pockets, thus obviating to best advantage the deposition or accumulation thereon of butter fat or other constituents of the liquid under treatment.
A further object is to provide a simpler and more economical and effective method of spacing the disks in the bowl.
A more specific object of the invention is to provide an improved disk which may be readily assembled with others in a bowl and insure more efficient operation.
The invention will now be particularly described with reference to the accompanying drawing, in which Figure 1 is a side view of one of the disks,
Figure 2 is a plan view of the same, and
Figure 3 is a sectional view of a plurality of disks in assembled relation with the spacing members somewhat exaggerated in size.
In the drawing, i represents the disks of the invention and 2 a plain disk which is placed between the disks in assembly in the bowl of the separator. Each of the disks I and 2 has the usual holes 3 arranged therein, as shown, and is frustro-conical in form with an outturned periphery 4 at its lower end and an inturned flange 5 at the, top, the flange 5 being provided with a recess 6 for location of the disks in assembled relation in the bowl of the separator.
The disk I is provided with a series of uniformly disposed internal and external integral spacing members 1 and 8 formed by pressing the metal wall of the disk at such points in such a way as to provide no folds or pockets and leave the surrounding metal of the wall in its original contour. These spacing members are of small dimensions and project from the wall of the disk only sufficient distance to afford the desired space be tween adjacent disks in the assembly. Considering a single spacing member it will be observed that the deflected portions 9 merge smoothly into the wall of the disk and the bearing portion II), which is itself disposed in a plane parallel with the disk wall. These spacers are so positioned on the disks that when the latter are assembled the pressed-out portions of the metal of each disk will come directly in substantially vertical line with similar portions on other disks. It will be 5 observed that this provides what is substantially a column of bearing metal which is parallel to the axis of the assembled conical disks. Thus when the usual pressure is exerted upon the assembled disks in a direction parallel to their axis, 10 the load will be taken up by this bearing column which is laterally supported by the rest of the metal of the disk. Thus the compression force is transmitted from disk to disk substantially without eccentric loading at any point, avoiding the tendency to bend the column out of its normal position or change the shape of any part of the several disks.
Only substantially half the disks are deformed, thus effecting an economy, and the plain disks alternately arranged with the deformed disks form part of the compression column at the same time avoiding the possibility of the spacers nesting one within the other.
The number of spacers in the deformed disk may be varied although the six series disclosed have given entire satisfaction, each series consisting of the external and internal spacer adjacent the top of the disk and a similar pair of spacers adjacent the bottom, thus providing two pressuresupporting vertical columns in the disk assembly, insuring maintenance of uniform contour of all the disks under all operating conditions. There is, accordingly, no irregularity in the radial flow of the milk and cream or the constituents of other material under treatment. Of course, the spacers are made as small as practically possible so as to avoid undue interference with liquid How.
It will be apparent that from the point of view of manufacture the present invention affords im- 0 portant economies, at the same time affording greater pressure-bearing capacity in the assembled disks without distortion of the latter. As previously indicated, there is no distortion of the disks so that uniform passages are maintained without any restriction of liquid flow and the spacers are so formed as to leave no noncleaning surfaces for the accumulation of materials. Furthermore, the spacers are of such character as to afford maximum ease in washing which is so important in devices of this character. The disks may be employed in separator bowls of the usual character without change in the construction of the latter.
. I claim:
1. In a centrifugal separator, a plurality of deformed and-plain frustro-conical disks arranged alternately in assembled form, said deformed disks having a plurality of internal and external spacers arranged in pairs, each spacer having a fiat portion in a plane parallel with the wall of the disk for engagement with a plain disk, said internal and external spacers being so arranged that in assembled form said fiat portions and the engaged portions of the plain disks form a bearing column disposed parallel to the axis of the assem gaging the plain disks and constituting stressbearing columns parallel with the axis of the assembly, said columns being disposed in pairs,
one being adjacent the top of the disks, the other adjacent the bottom thereof.
4. A disk for centrifugal separators, said disk being frustro-conical in form andhavingaplurality of internal and external spacers thereon formed by deformation of its wall, each of said spacers having a bearing surface in a plane parallel with the wall of the disk and inclined side portions merging with said bearing surface and the wall of the disk and affording lateral support for the bearing surface, said internal and external spacers being arranged in pairs having an integral portion connecting the two bearing surfaces of each pair and said portion being inclined with respect to the wall of the disk to support said bearing surfaces.
5. A frustro-conical disk for centrifugalseparators having at a plurality of spaced points in its walla pair of displaced interconnected portions forming an internal and an external bearing surface each integral with and disposed in a plane parallel to the wall of said disk and the portion connecting said internal and external bearing surfaces being disposed at an obtuse angle with respect to said surfaces.
