Abstract
Device for adding a fluid to a liquid, for example of gas and/or particles to liquid metal. A rotor is rotated immersed in the liquid, comprising a hollow rotational body 10 with a first inner annular wall 16 with at least one radial opening 18 from a central, cylindrical chamber 19 and with an opening directed downwards. The rotational body is carried by a generally vertical shaft 12 which is connected to a powering unit and which may be arranged to lift the rotational body out of, respectively lower it into the liquid. Outside the central annular wall 16 of the rotational body 10 a further annular wall 14 which forms an annular chamber 17 is arranged, which communicates with the central chamber through the one or more radial openings 18. Advantages are achieved by that the one or more of the radial openings 18 are arranged in the lower part of the inner annular wall 16 of the rotational body, in a area which projects down under the surrounding additional annular wall 14.
