d'assiettes, en deux compartiments par au moins une

  
paroi séparatrice, en assurant l'alimentation de telle 

  
façon que la centrifugation ait pour effet de séparer

  
et faire passer respectivement les deux phases liquides 

  
dans ces deux groupes, d'où elles sont évacuées par 

  
des conduits distincts, tandis que les sédiments peu- ' vent se séparer dans une zone extérieure de rayon  maximum. 

  
Elle consiste, mise à part cette disposition '

modes d'application ainsi que certains modes de réali..  sation, desdites dispositions; et elle vise plus parti-  culièrement encore, et ce à titre de produits industriels  nouveaux, les séparateurs du genre en question ainsi 

  
que les éléments spéciaux propres à leur établissement 

  
 <EMI ID=4.1> 

  
Et elle pourra, de toute façon, être bien 

  
 <EMI ID=5.1> 

  
d'indication. 

  
La figure unique, de ce dessin, montre en  coupe axiale partielle un séparateur centrifuge à 

  
empilage d'assiettes, établi conformément à l'invention.

  
Selon l'invention, et plus spécialement selon 

  
 <EMI ID=6.1> 

  
 <EMI ID=7.1> 

  
il semble qu'il y ait lieu d'accorder la préférence,  se proposant par exemple d'établir un séparateur centri- j fuge, notamment à empilage d'assiettes, pour séparer  trois phases comprenant un liquide léger, un liquide  lourd et une phase solide lourde de densité supérieure  à celles des deux liquides, on s'y prend comme suit  ou d'une façon analogue.

  
On agence cet appareil, dans son ensemble,

  
d'une façon appropriée usuelle, c'est-à-dire en lui faisant comprendre essentiellement un bol que l'on

  
monte par exemple sur un pivot vertical entraîné en  rotation, et on divise l'intérieur de cet appareil '

  
en deux compartiments alimentés de telle façon que les deux phases liquides tendent à se séparer respectivement dans lesdits compartiments, tandis que la phase solide, c'est-à-dire les sédiments, sont évacués à la périphérie du bol, dans sa partie la plus large.

  
A supposer, comme on va le faire dans ce qui  suit, que l'empilage soit de forme tronconique, on fait  en sorte que ces deux empilages d'assiettes soient divisés  par au moins une cloison séparatrice de forme appropriée, 

  
En outre, de préférence, on fait en sorte que

  
la suspension à traiter soit introduite dans l'un desdits compartiments, en l'espèce le compartiment inférieur et à un point intermédiaire, c'est-à-dire à un rayon intermédiaire entre les deux rayons extrêmes 

  
de l'empilage correspondant. 

  
C'est ainsi qu'on peut notamment recourir au mode de réalisation qui est représenté sur le dessin

  
et qui va maintenant être décrit.

  
On fait comporter à l'appareil en question 

  
un moyeu 1, que l'on monte sur le pivot 2 de l'appareil, ce moyeu étant creux en 3 pour l'introduction de la suspension à traiter, laquelle suspension est distribuée par des conduits 4 venant déboucher à un niveau intermédiaire sur le cône 5 prévu à la base de l'appareil et  <EMI ID=8.1> 

  
pendant que l'introduction de la suspension pourrait se faire de toute autre manière.

  
Le deuxième empilage d'assiettes 8 est disposé au-dessus du premier dans un espace demeurant libre

  
entre la cloison séparatrice susvisée, représentée en 9,

  
et la partie 10 de la paroi extérieure 11 du bol.

  
Ladite cloison séparatrice 9, qui est de forme tronconique appropriée à celle des assiettes, est par exemple solidaire d'un deuxième manchon 12 entourant le  premier 1 et destiné à constituer, comme on va le  nontrer, un passage annulaire 13 pour l'évacuation d'une des deux phases liquides. 

  
Enfin, l'ensemble est complété, pour permettre d'évacuer dans la partie annulaire extérieure 14 du bol

  
les matières solides ou sédiments, par des moyens comprenant tous systèmes de valves d'un type connu 15,

  
 <EMI ID=9.1> 

  
L'ensemble fonctionne de la façon suivante"  La suspension arrivant par l'intérieur du 

  
 <EMI ID=10.1> 

  
dans la partie inférieure du bol, c'est-à-dire dans le  premier empilage d'assiettes qui occupe par exemple, 

  
en encombrement, le tiers environ dudit bol. 

  
Sous l'effet de la centrifugation le liquide léger est ramené vers le centre dé l'appareil et est  <EMI ID=11.1> 

  
prement dit est amené à traverser le deuxième empilage d'assiettes et à s'évacuer, après clarification, dans.

  
 <EMI ID=12.1> 

  
Il est entendu que l'évacuation des sédiments peut se faire suivant les dispositions usuelles connues, c'est-à-dire que l'on peut prévoir notamment:

  
l'évacuation commandée,

  
l'évacuation automatique à travers des buses, l'évacuation automatique contrôlée à travers

  
des valves telles que 15, 

  
ou encore l'évacuation motorisée à travers des  lumières périphériques. 

  
Les séparateurs, conformes à l'invention,

  
peuvent se prêter à toutes applications, en particulier

  
à l'extraction des levures ou protéines contenues d'ans

  
 <EMI ID=13.1> 

  
rentes, le gas-oil proprement dit, l'eau et le&#65533; levures,  ces dernières constituant l'élément le plus lourd.

  
En suite de quoi, quel que soit le mode de  réalisation adopté, on peut établir des séparateurs dont  le fonctionnement ressort suffisamment de ce qui pré-  cède pour qu'il soit inutile d'insister à son sujet, 

  
 <EMI ID=14.1> 

  
en question déjà existants, de nombreux avantages, no-  tamment : 
- de meilleures possibilités de clarification, . 
- et, en même temps, une grande simplicité  entraînant un prix de revient peu élevé.. 

  
 <EMI ID=15.1> 

  
aussi au cas où la séparation se ferait sans utiliser  des assiettes, tout au moins dans la partie intérieure 

  
de l'appareil (les assiettes 6 étant donc supprimées au  moins partiellement). 

  
Comme il va de soi, et comme il résulte  d'ailleurs déjà.de ce qui précède, l'invention ne se  limite nullement à ceux de ses modes d'application,

It consists, apart from this provision '

that the special elements specific to their establishment

indication.

  
The single figure, of this drawing, shows in partial axial section a centrifugal separator with

  
stacking of plates, established in accordance with the invention.

  
According to the invention, and more especially according to

  
 <EMI ID = 6.1>

  
 <EMI ID = 7.1>

  
it seems that it is appropriate to grant the preference, proposing for example to establish a centrifugal separator, in particular with stacking plates, to separate three phases comprising a light liquid, a heavy liquid and a phase A heavy solid with a density greater than those of the two liquids, the procedure is as follows or in a similar manner.

  
We arrange this device, as a whole,

  
in a customary appropriate manner, that is to say by making him understand essentially a bowl that we

  
mounts for example on a vertical pivot driven in rotation, and we divide the interior of this device '

  
into two compartments fed in such a way that the two liquid phases tend to separate respectively in said compartments, while the solid phase, that is to say the sediments, are discharged at the periphery of the bowl, in its most part. large.

  
Assuming, as will be done in what follows, that the stack is frustoconical, it is ensured that these two stacks of plates are divided by at least one separating wall of appropriate shape,

  
Further, preferably, it is ensured that

  
the suspension to be treated is introduced into one of said compartments, in this case the lower compartment and at an intermediate point, that is to say at an intermediate radius between the two end radii

  
of the corresponding stack.

  
It is thus in particular that one can resort to the embodiment which is represented in the drawing

  
and which will now be described.

  
The device in question is made to behave

  
a hub 1, which is mounted on the pivot 2 of the device, this hub being hollow at 3 for the introduction of the suspension to be treated, which suspension is distributed by ducts 4 coming to an intermediate level on the cone 5 provided at the base of the device and <EMI ID = 8.1>

  
while the introduction of the suspension could be done in any other way.

  
The second stack of plates 8 is placed above the first in a space that remains free

  
between the aforementioned dividing wall, shown at 9,

  
and part 10 of the outer wall 11 of the bowl.

  
Said dividing wall 9, which is of a frustoconical shape appropriate to that of the plates, is for example integral with a second sleeve 12 surrounding the first 1 and intended to constitute, as will be shown, an annular passage 13 for the evacuation of one of the two liquid phases.

  
Finally, the assembly is completed, to allow evacuation in the outer annular part 14 of the bowl

  
solids or sediments, by means comprising all valve systems of a known type 15,

  
 <EMI ID = 9.1>

  
The assembly works as follows: "The suspension arriving from inside the

  
 <EMI ID = 10.1>

  
in the lower part of the bowl, that is to say in the first stack of plates which occupies for example,

  
in size, about a third of said bowl.

  
Under the effect of centrifugation, the light liquid is brought back to the center of the device and is <EMI ID = 11.1>

  
prement said is made to pass through the second stack of plates and to evacuate, after clarification, in.

  
 <EMI ID = 12.1>

  
It is understood that the evacuation of the sediments can be done according to the usual known arrangements, that is to say that one can provide in particular:

  
controlled evacuation,

  
automatic evacuation through nozzles, automatic evacuation controlled through

  
valves such as 15,

  
or even motorized evacuation through peripheral lights.

  
The separators, according to the invention,

  
can lend themselves to all applications, in particular

  
to the extraction of yeasts or proteins contained in years

  
 <EMI ID = 13.1>

  
rents, the diesel itself, water and &#65533; yeasts, the latter constituting the heaviest element.

  
As a result, whatever the embodiment adopted, it is possible to establish separators whose operation emerges sufficiently from the above for it to be unnecessary to dwell on it,

  
 <EMI ID = 14.1>

  
in question already existing, many advantages, in particular:
- better possibilities for clarification,.
- and, at the same time, great simplicity resulting in a low cost price.

  
 <EMI ID = 15.1>

  
also in case the separation is done without using plates, at least in the interior part

  
of the device (the plates 6 therefore being removed at least partially).

  
As goes without saying, and as it follows moreover from the foregoing, the invention is in no way limited to those of its modes of application,

  
 <EMI ID = 16.1>

  
various parts, having been more especially considered; on the contrary, it embraces all the variants.
