Abstract
Pending liquid is led through a centrifugal pipeline 1, presses different densities and separates, and two kinds of liquid piping 4 and 5 that communicates is discharged.This whizzer comprises: seal disc (6,11 and 19), these dishes are separately fixed on the middle body of rotor 7 of this equipment, on the telophragma 12 and on the upper end cover 20.Rotating ring (8,13,14 and 17) presses these dishes.Each rotating ring is bearing pressure that imports the liquid in the separator and the different pressure that are separated into two kinds of liquid phases by centrifugal action that bearing owing to proportion.Like this, just obtain guaranteeing, and do not need the biasing force device also not need special external refrigeration simultaneously in the sealing fully between the homophase not.
Description
The present invention relates to a kind of whizzer that is used for various liquid, particularly preparation is used for milk industry but also can be used for mineral oil, vegetable oil or other liquid mixture, because action of centrifugal force, liquid is separated into the different component of different densities.
The whizzer of this pattern is introduced in submitting and transferred same assignee's 85.629/A/86 disclosures in Italian patent application on November 5th, 1986 to some extent.The subject content of this application is as the application's coherent reference data.
Mention in the above-mentioned patent application, various liquid with different densities are to separate under the centrifugal action of separator, and its separation process is to distribute according to various objectives by formed each pipeline in the fixedly end cap of this equipment then by rising in the formed annular concentric pipeline in the rotating part of this equipment.
In above-mentioned patent application, is to guarantee by some rotating rings that can rotate with the rotating part of equipment the rotating part of equipment with the fixing gas-tight seal between the end cap, the ring on the top that rotating ring is fixing with flexibly being fixed on equipment contacts, and in fact this structure has been eliminated the possibility that various liquid contact with atmosphere.Be provided with some suitable pipelines so that have the cooling water of certain pressure and flow through, purpose is that retainer ring and the rotating ring that guarantees sealing cooled off.
In equipment according to above-mentioned patent application, the suitable spring that mat acts on the ring that does not change has guaranteed the sealing between rotating ring and retainer ring, because the ring that does not change is placed on the standing part of equipment and the effect of bearing the compression spring, and the compression spring pushes away under the hoop.Therefore, force the environmental protection of not changeing to be held and contact, avoid like this mixing once more owing to the various liquid that centrifugal force separates with rotating ring on the rotating part that is positioned at equipment.
But, this solution produces some defective, mainly be to be used for the complexity of hydraulic circuit of fluid separation applications and the structural weak of compression spring, and this spring need be controlled continuously and since the character needs of the liquid that separated change continually.
The objective of the invention is to improve the whizzer of above-mentioned patent application and those defectives of being mentioned above the elimination.
In the present invention the fixedly end cap of equipment has been carried out substantial simplification and guaranteed sealing between several axial pipelines with forming ring, and the motion of the fixed part of the relative equipment of forming ring.It is owing to the fluid pressure that acts on the rotating ring that these rotating rings are held contact with the environmental protection that the rotatable parts of relative equipment are fixed, the substance simplification that so just obtains the hydraulic circuit of equipment also at first makes the spring of various types be cancelled, and the Operation and Maintenance of equipment is simplified.
In more detail, the displacement that encircles during sealing makes the liquid component in the equipment directly surround ring, in fact cause encircling the absorption of the heat that produces at the volley, the necessity that liquid cools is carried out in the water circulation that provides with above-mentioned patent application so just has been provided.
Below with reference to accompanying drawings the present invention is explained in more detail, wherein;
Fig. 1 is the axial partial cutaway diagrammatic sketch that has the whizzer top of rotary seal of the present invention.
As shown in Figure 1, pending liquid imports whizzer by center tube 1, be separated into the different liquid of two kinds of proportion mutually after by coaxial pipes 2 and 3 discharges.Particularly the more low-gravity liquid that rises through axially inboard pipeline 2 is taken to the coaxial pipes 4 in the fixedly end cap exit of the equipment of being arranged on, and standing part outlet 5 discharges of liquid through being arranged on equipment of the high specific weight that rises by the coaxial pipes 3 in the axial outside.Each arrow among the figure is the course of expression different liquids phase.
Entering sealing between the pipeline 1 and the first axial discharge line 2 in central authorities, is to guarantee by the ring 6 that is fixed on rotor middle body 7.Rotating ring 8 is waken the argon chaff with rotor and is contacted.Rotating ring 8 is coaxial with mesotube 1, and in pipeline 1 under the thrust of fluid pressure, with its upper lip 8 ' contact with retainer ring 6.Fluid pressure is along the directive effect of arrow 9.
Similar with it, the sealing between coaxial pipes 2 and 3 the liquid guarantees with retainer ring 11.It is fixed in dish 12.Coil 12 closed upper portion parts, pipeline 2 and two rings 13,14.The stroke of ring 13 and 14 is to limit by the stop block element 15 and 16 that is fixed in pipeline 4.Two rings 13 and 14 are bearing respectively from the pressure of the light liquid mutually of pipeline 2 with from the pressure of the heavy phase liquid of pipeline 3.
Similar with it, outside seal is by guaranteeing with the coaxial rotating ring 17 of external pipe 5, and the motion of this ring 17 is to limit by a stop block element 18 that is fixed on pipeline 5 outer walls.This outside seal is also guaranteed by the retainer ring 19 that is fixed on equipment end cap 20.
The various advantages that the present invention brings, particularly the advantage with the whizzer end cap of introducing in the relative disclosures in Italian patent application 85.629/A/86 of liquid centrifugal separator end cap number of rotary seal is very clearly, not only have substantial simplification but also at first be owing to cancelled particularly spring of flexible member in the structure aspects of equipment, because the sealing between rotating ring and the retainer ring is to guarantee by the same pressure of liquid effects on same rotating ring.
It is again emphasized that, cool off with same liquid at ring and have substantial advantage, the cooling that so just need not provide cold water under pressure, to circulate.
Obviously, this equipment is described for a specific embodiment by reference to the accompanying drawings, but, it is only described with infinite giving an example because concrete CONSTRUCTED SPECIFICATION can in shape with different aspect carry out various changes and essential characteristic of the present invention still remains unchanged.
