COMPLETE SPECIFICATION.
Improvements in Centrifugal Separators.
I, ERIK GUSTAF NICOLAUS SALENIUS, of Aktiebolaget Radiator, Albano, in the
Kingdom of Sweden, Mechanical Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
This invention relates to centrifugal vessels.
The centrifugal vessel forming the subject of the present invention is provided
with double walls, so to speak, being composed of an outer cylinder and a
series of rings in the latter, placed one upon another, and forming an interior
wall.
The advantages of this arrangement are partly due to the fact that the interior
rings, which are easy to make, absorb an important part of the pressure during
the rotation, there being therefore no necessity for making the thickness of the
metal of the outer cylinder as great as is customary it being therefore possible to
manufacture the said cylinder more cheaply than the centrifugal vessels heretofore
used, and partly to the possibility of fixing the said rings to the internal plates
which in the well-known manner serve to divide the vessel axially into a number
of compartments, the said plates being thus held firmly in place.
In the accompanying drawing,
Figure 1 shows a vertical section of a centrifugal vessel of the kind in question,
and
Figure 2 is a horizontal section of the said vessel taken just above the bottom
thereof.
a is the outer cylinder and 6 the rings forming short cylinders placed one upon
another in the said cylinder a. The joints between the said rings are made tight
by interposed elastic rings c which are forced together between the cover d and
the bottom e, the said cover being held down by the screw f, and the bottom
being attached to the cylinder a by means of an arrangement resembling a
bayonet-joint, so as to allow of its being detached. To each ring is connected a
plate G of the well-known conical shape. Next to the ring the plate is provided
with perforations through which the skim-milk passes up to the discharge
pipe. The said plates can evidently be made of different shape from that shown
in the drawing, for instance as plane surfaces, as short screw-threads or the like,
and in each case either smooth or corrugated. It is moreover, possible to connect
more than one plate to each ring.
Having now particularly described and ascertained the nature of my said
nvention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A centrifugal vessel composed of a number of rings (b) placed one upon
nother in an outer cylinder (a) in which they are made to fit and which rings
re connected respectively to plates (g) of the well-known conical shape, or in the

page_text: shape of screw-threads, plane surfaces or of other form, for the purpose of pro-
viding the centrifugal vessel with double walls, so to speak, the inner wall being
formed by the rings, and at the same time holding the said plates firmly in place.
2. An arrangement as specified in Claim 1, in which two or more of the plates
are connected to each ring.
