Improvements in Centrifugal Separator Drums.
1, SOPHUS CHRISTOPHER HAUBERG of No. 32 Tagensvej Copenhagen,
Denmark, Manufacturer 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 :-
Heretofore in centrifugal separators the fluid to be treated usually makes one
turn in the drum on its way from the inlet to the outlet. Now according to my
improvements the fluid is forced to take two or more turns in the drum which for
this purpose is divided in separate superposed compartments. These compartments
are either formed by means of one or more annular cross partitions which are
vertical upon the axis of rotation of drum and are provided with radial upstanding
partitions or by means of helical surfaces around the axis of rotation.
The first named arrangement is shewn in the vertical sections Figures 1 and 3 on
lines A B of the corresponding plan sections Figures 2 and 4; and the last named
arrangement is shewn in Figures 5 and 6.
In Figures 1 to 4 is only shewn one annular partition whereby the fluid is
forced to pass round twice in the drum from the inlet, which takes place by the
fixed feed pipe a and the pipe b that rotates with the drum, to the outlet which takes
place as regards the heavier part of the fluid by the pipe cand as regards the lighter
part by the outlet opening 9. The fluid issues from the pipe 6 under the cross
partition e on one side of the radial upstanding partition or carrier wing d between
the bottom of the drum and the cross partition e and thence under the latter around
in the drum to the opposite side of the radial partition d, where it passes up through
an opening in the cross partition e into the compartment above the latter in order
there to pass from one side of a radial upstanding partition in the said upper
compartment around in the drum to the opposite side of the partition d², where the
outlet e for the heavier fluid is situated, either as shewn in Figures 1 and 2 in the
same direction as under the partition e or as in Figures 3 and 4 in the opposite
direction; all as indicated by the double row of arrows in Figures 2 and 4
respectively.
For it will be noticed that the radial partition d and d in Figures 1 and 2 are
one on one side and the other on the other side of the opening whereas in
Figures 3 and 4 the partition d³ forms an upper continuation of the partition d.
In Figures 5 and 6 the drum is provided with a surface e which winds helically
around the axis of rotation. The fluid issues from the pipe b under the lower part
of the surface e, the outlet c for the heavier part of the fluid is above it, and 9 is
the outlet for the lighter portion such as cream if the apparatus is used as a milk
separator.
By these improvements I obtain a larger passage for the fluid and less disturbing
actions therein, inasmuch as the commotion in the fluid in the drum caused by the
inlet is confined to act at most upon the first turn of the fluid in the drum.
Having now particularly described and ascertained the nature of my said inven-
tion and what manner the same is to be performed I declare that what I
claim is :-
1. In centrifugal separator drums the application and use of one or more
partitions vertical to the axis of rotation and having straight or curved surfaces
which either have openings in combination with radial carrier partitions or form a
continuous winding surface whereby that part of the contents of the drum which
contains the fluid ring is formed into a continuous channel through which the fluid
must pass on its way from the inlet to the outlet, thus compelling the fluid to move

page_text: one or more times round in the drum before it leaves it substantially as set forth
and for the purpose of obtaining a longer passage for the fluid and a quick
annulling of the disturbing influences produced by the inlet of the fluid into the
drum.
2. The constructions of centrifugal separator drums shewn on the drawing.
