Title (EN) DEVICE FOR ADDING OXYGEN TO WATER
(FR) DISPOSITIF D'OXYGENATION DE L'EAU
Abstract:
(EN) Hydro-cyclone with a cyclone (1) that has its narrow end (2) turned upwards and its wider end (3) with the inlet (4) turned downwards. The inlet (4) is arranged tangentially and in the bottom of the cyclone a central outlet (7) is arranged. To the cyclone inlet (4) the water comes from a pump (5) that in turn is driven by a motor. The lower outlet from the center of the cyclone ends in a hose delivering the major part of the water and through the upper outlet air is sucked into the cyclone and mixed and dispersed with water in this so that an efficient oxygenizing of this is obtained.
(FR) La présente invention concerne un hydrocyclone pourvu d'un cyclone (1) dont l'extrémité étroite (2) est tournée vers le haut et dont l'extrémité plus large (3), comportant l'admission (4), est tournée vers le bas. L'admission (4) est disposée tangentiellement, une évacuation centrale (7) étant ménagée dans le fond du cyclone. Du côté de l'admission de cyclone (4), l'eau vient d'une pompe (5) entraînée, quand à elle, par un moteur. L'évacuation de fond partant du centre du cyclone aboutit dans un tuyau débitant la majeure partie de l'eau, l'air étant aspiré dans le cyclone par l'évacuation supérieure, et mélangé puis dispersé avec l'eau dans le cyclone de façon à réaliser une oxygénation efficace.
