Improvement in Centrifugal Separators.
Year: 1896

page_text: Improvement in Centrifugal Separators.
I, ERIK NYLÉN, of Riddaregatan 70, Stockholm, Sweden, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to centrifugal separators for separating matters suspended
in liquids and relates particularly to such separators as may be employed in
separating such matters as the utricles of yeast from the water with which they
are mixed or kaolin (porcelain clay) from the water in which it has been washed.
As is well known, the separators of the class referred to have to be constructed in
such a manner that the peripheral sectional area of the separator drum (areas of
discharge channels for the heavier particles) is more and more reduced as the
diameter of the drum increases, in order to prevent the immediate discharge of the
liquid admitted, before it has undergone separation and to enable the heavier
particles to slide or sweep along the walls towards the discharge opening for the
same in such a way that the centrifugal force progressively acts stronger on them
as they arrive nearer the discharge-orifice. As the said reduction of the peripheral
sectional area of the drum requires to be different for the different liquids to be
treated, the same separator is not suitable for treating all kinds of liquids.
The object of this invention is to provide a separator so constructed that it
may be easily changed so as to be suitable for treating different kinds of liquids
or to be more easily adjusted for a certain kind of liquid. The invention consists,
briefly speaking, in constructing the separator drum with removable reduction
blocks which may be replaced by similar blocks of a size corresponding to the
areas necessary for the liquid that is to be treated in the drum. The said re-
duction blocks may be made in many different sizes corresponding to different
liquids and kept in stock for each machine. By putting in reduction-blocks
of the right size into the circular drum of a centrifugal separator, the same may
be easily changed so as to be suitable for treating different kinds of liquid at
the same speed, so that no change of the driving machinery is necessary. By
leaving out the reduction blocks the same separator and machinery may be used
for skimming milk. The blocks may be fastened from the outside or inside
by screws, bolts etc. and the blocks are to be particularly made and adjusted for
each particular separator when running at certain speed and when used for a
particular mixture. The blocks may of course be either solid or hollow, as
desired. The blocks may also be made in such manner that their form is adjus-
able, 30 that the same blocks may be used. This can be accomplished,, for
instance, by adding or removing a piece or layer from the block or having the
block expansive by means of screws or the like.

I, ERIK NYLÉN, of Riddaregatan 70, Stockholm, Sweden, 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:-
This invention relates to centrifugal separators for separating matters suspended
in liquids and relates particularly to such separators as may be employed in
separating such matters as the utricles of yeast from the water with which they
are mixed or kaolin (porcelain clay) from the water in which it has been washed.
As is well known, the separators of the class referred to have to be constructed in
such a manner that the peripheral sectional area of the separator drum (area of
discharge channels for the heavier particles) is more and more reduced as the
diameter of the drum increases, in order to prevent the immediate discharge of the
liquid admitted, before it has undergone separation and to enable the heavier
particles to slide or sweep along the walls towards the discharge opening for the same
in such a way that the centrifugal force progressively acts more strongly on them
as they arrive nearer the discharge-orifice. As the said reduction of the peripheral
sectional area of the drum requires to be different for the different liquids to be
treated, the same separator is not suitable for treating all kinds of liquids.
The object of this invention is to provide a separator so constructed that it
may be easily changed so as to be suitable for treating different kinds of liquids
or to be more easily adjusted for a certain kind of liquid.
The invention consists, briefly speaking, in constructing the separator drum
with removable reduction blocks or partitions which may be replaced by similar
blocks or partitions of a size corresponding to the areas necessary for the liquid
that is to be treated in the drum. The said reduction blocks may be made in
many different sizes corresponding to different liquids and kept in stock for each
machine. By putting in reduction-blocks of the right size into the circular
drum of a centrifugal separator, the same may be easily changed so as to be
suitable for treating different kinds of liquid at the same speed, so that no change
of the driving machinery is necessary. By leaving out the reduction blocks the
same separator and machinery may be used for skimming milk. The blocks
may be fastened from the outside or inside by screws, bolts etc. and the blocks
are to be particularly made and adjusted for each particular separator when
running at certain speed and when used for a particular mixture. The blocks
may of course be either solid or hollow, as desired. The blocks may also be
made in such manner that their form is adjustable, so that the same blocks may
be used. This can be accomplished, for instance, by adding for removing a
piece or layer from the block or having the block expansive by means of screws
or the like.
In the accompanying drawings Figure 1 shows a vertical section of a
separator drum, constructed according to this invention, and Fig. 2 is a sectional
plan-view on the line - in Fig. 1.
Referring to the drawings by letters (like letters referring to the same parts in
the different figures) A represents a circular separator drum, of the kind commonly
used for skimming milk, provided with two discharge orifices a. Between the
said orifices reduction blocks b are removably fastened to the wall of the drum by
screws c or the like in such a manner that the peripheral sectional areas (areas
of discharge-channels for the heavier particles) are reduced.

page_text: Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
A centrifugal separator having the reduction blocks or partitions removable
substantially as and for the purpose set forth.
