Equipment for the treatment of a liquid such as a metal melt has one or more rotors ( ) for the supply of gas and/or particulate material to the liquid in a reaction chamber ( ). The reaction chamber ( ) is closed and has an inlet ( ) and an outlet ( ) and is designed to be placed under a vacuum. The outlet ( ) communicates with another chamber or outlet passage ( ). The equipment may have several reaction chambers ( ) arranged in series. The first reaction chamber ( ) then communicates with the second reaction chamber ( ), the second reaction chamber with a third, etc. via an opening ( ).

Metal melt treatment equipment

A device in connection with a rotor ( ) for the treatment of a liquid such as molten metal in a reactor ( ) or similar structure. Gas and/or particulate material is supplied to the liquid, preferably via the rotor shaft ( ) and through openings ( ) from a cavity ( ) in the rotor. The rotor shaft ( ) extends up through the base of the reactor ( ) and is arranged so that it may rotate inside a stator pipe ( ) which extends up from the base of the reactor. The rotor shaft and the stator pipe extend through an opening ( ) in the lower side of the rotor ( ) and into the cavity ( ) in the rotor. Expediently, the rotor shaft ( ) is connected to the rotor ( ) via a fixing device ( ) inside the rotor cavity, while the stator pipe ( ) ends in the cavity ( ).
