Improvements in Centrifugal Separators.
1, GEORGE HUGHES, Patent Agent, of 23 Coleman Street in the County of
London, (a communication from Curt Count zur Lippe, Landowner, Martinwalden,
Post Kaisers Walden, near Bunzlau, Silesia), 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 more especially to centrifugal separators of a circular
shape in which the separating chamber is divided by a radial partition, the milk
being fed in on one side, and the skim milk and cream led off on the other side.
The improvement consists mainly in the addition of suitable partitions to the
separator by means of which the distance to be traversed by the milk on its way
from the entrance to the exit is lengthened.
Fig. 1 of the accompanying set of drawings shows one of my improved separators
in longitudinal section.
Fig. 2 is a cross section, and Fig. 3 a development of a section through the
circle in Fig. 2 as seen from outside.
The milk is fed in through the pipe a, which starts from the circular cavity
of the drum-like insertion b. The milk now Hows in a ring on the inner surface
of the drum c. In separators of this kind which have hitherto been in use the
milk flows in an absolutely vertical direction, whereas in my improved separator
the milk is compelled by the strips & d to flow in zig-zag lines. Furthermore
these strips d and divide the stream of liquid into several jets. These
strips and are made of metal or other suitable material tangentially
arranged as regards the centre of the separator, parallel as regards each other
and slantingly as regards the length of the drum. In the illustration each outlet
consists of three such strips d'and. The strip d', which is on the outer side
fixed to the inside of the drum and free towards the inner side, is connected at the
top end to the lid c' of the drum c. The bottom end is free, and bent at a right
angle in the direction indicated by the arrows, which also indicate the direction of
the flow of the milk. The middle strip is fixed on its outward side to the
drum c.
The top and bottom parts are respectively bent forward and backward in
order to get into a vertical position. The last strip is free at its top end, and
bent backwards and its bottom end is fixed to the bottom c² of the drum
Channels are thus created which are open towards the inside and also slanting
from top to bottom. In the illustrations these channels have their lower ends
in advance of their upper ends as regards direction of rotation. A reverse arrange-
ment might be employed, or one partaking partly of one arrangement and partly
of the other. The exit of the cream and skimmed milk takes place through the
pipes for g respectively, which are placed behind the partition e.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what
clain is,
In centrifugal separators the combination of parts operating substantially as
