Definitions
- the tightening connection of the feed pipe with the centrifugal drum is obtained by an annular chamber disposed at the point of connection in concentric relation to the axis of rotation, a rotary member or body dipping or projecting into said annular chamber, one of the said parts being connected with the rotating drum and the other one with the stationary connecting pipe, and means adapted to entrain the liquid being provided within the annular chamber on the side facing the air gap of the revolving part, and braking means, adapted to retard the liquid being provided on the side of the stationary part facing the liquid gap, on one only of the said means being provided.
- FIG. 1 One embodiment of the invention is shown by way of example in the drawing the figure of which is a fragmentary vertical section through the top of a centrifuge drum.
- the liquid to be centrifuged is fed through a stationary supply pipe I and a revolving inlet pipe 2 into the drum 3.
- the specifically heavier portion (skim milk) flows in known manner from the drum through channels 4 into an outlet chamber 5, from which it is conveyed by a collector 6 to an outlet 1.
- the specifically lighter portion (cream) is forced to the centre into a chamber 8 and is conveyed through an annular chamber 9 to outlets III.
- the upper inner wall of the stationary chamber- II facing a liquid gap I5 between the pipes I and 2 is provided with liquid-retarding ribs I3 andthe lower wall of the revolving annular member I2 facing an air gap I5a with liquid-entraining ribs I I. Since the liquid is thereby caused to rotate more rapidly near the ribs I 4 than at the spot near the ribs I3, an excess pressure is produced by the ribs I4 opposite to that produced by the ribs I3, which with correct adjustment counterbalances the pressure at the gap I5 which is about equal to the pressure in the inlet pipe I.
- the rectilineal passage from the supply pipe I to the inlet pipe 2 at the gap I5 prevents the traversing liquid from becoming admixed to any considerable extent with the sealing liquid in the chamber I I disposed outside of the liquid stream, so that the traversing centrifuge liquid remains practically uninfluenced by the sealing device.
- a stop-cock 24 mounted in the pipe 22, is provided with ports or passages of different sizes, a larger one for use during the beginning of the centrifuging operation for the passage of relatively large quantities of air and a smaller one for use during regular operation.
- the sealed connection shown in the drawing can of course be kinematically reversed in such a way that the chamber I I revolves and the member I2 remains stationary.
- the described sealing device connected with the inlet piping of the drum may be advantageously combined with a collector 6 for the discharge of the centrifuged liquid, as shown in the drawing.
- a collector 6 for the discharge of the centrifuged liquid
- the collector produces a pressure which counterbalances the pressure around the liquid gap I and within the chamber II.
- the chamber II is relieved from the pressure of the out-flowing liquid by the counterbalancing pressure in the collector and, thus, the chamber I I can be of smaller dimensions than in the case where a collector is not used.
- the said collector is preferably symmetrically shaped, as shown, and is radially arranged around the inlet pipe 2 to permit relative rotation of the inlet pipe with respect thereto. This arrangement does not essentially increase the constructional height of the machine or impair its operation.
- a centrifugal separator the combination with a pair of axially alined pipes in slightly spaced end to end relation, one of said pipes being connected to a drum and being revoluble with respect to the other, of a sealing means at the junction of said pipes, including an annular flange extending outwardly from the extremity of one of said pipes, a chamber carried by the end portion of the other pipe and enclosing said flange, fins projecting inwardly from a portion of the wall of said chamber and being adapted to produce a retarding action on the liquid, and other fins projecting from the flange on the side of the flange remote from the first mentioned fins, the said other fins being adapted to produce entraining of the liquid, an exit for said drum, piping leading away from the centrifuged liquid, and a liquid forcing means coaxially positioned at the exit of the drum and adapted to discharge centrifuged liquid and to produce a pressure in the piping leading away the centrifuged liquid.
- said liquid forcing means consisting of a revolving chamber positioned coaxially to the sealing means and enclosing a stationary collector adapted to discharge said part of the centrifuged liquid.
