Title (EN) SEPARATOR FOR SEPARATION OF TWO LIQUIDS
(FR) SEPARATEUR DESTINE A LA SEPARATION DE DEUX LIQUIDES
Abstract:
(EN) A separator for the separation of two intermixed liquids having two different specific weights, for example, water and oil, comprising a rotating separator bowl (2) having coaxial outlet openings (5, 25, 37) of different diameters, where the separator bowl (2) is divided into two chambers by rotation-symmetrical transverse walls (15, 16) allowing flow communication between the chambers and where an inlet pipe is provided for supplying the intermixed liquids into a first chamber, which is characterized in that the coaxial outlet opening (5) having the smallest diameter is situated in the first chamber, that the rotation-symmetrical walls (15, 16) are provided with one or more coaxial opening(s) (17, 28) of greater diameter than the outlet opening (5) from the first chamber, and that in the end of the separator opposite the first chamber and the coaxial outlet opening (5) from the first chamber are provided two coaxial openings (25, 37) of different diameters.
(FR) Cette invention concerne un séparateur destiné à la séparation de deux liquides mélangés et ayant deux poids spécifiques différents, par exemple de l'eau et de l'huile. Ce séparateur comprend un récipient de séparation rotatif (2) qui comporte des orifices d'évacuation coaxiaux (5, 25, 37) de diamètres différents. Ce récipient de séparation (2) est divisé en deux chambres par des parois transversales (15, 16) et symétriques en rotation qui assurent la communication du fluide entre lesdites deux chambres, un tuyau d'admission assurant, quant à lui, l'arrivée des liquides mélangés dans la première chambre. Ce système se caractérise par le fait que l'orifice d'évacuation coaxial (5) ayant le plus petit diamètre est situé dans la première chambre, que les parois symétriques en rotation (15, 16) comportent un ou plusieurs orifices coaxiaux (17, 18) d'un diamètre supérieur à celui de l'orifice d'évacuation (5) de la première chambre, et qu'à l'extrémité du séparateur, à l'opposé de la première chambre et de l'orifice d'évacuation coaxial (5) de ladite première chambre, se trouvent deux orifices coaxiaux (25, 37) ayant des diamètres différents.
