摘要： PURPOSE:To improve the suction and removal efficiency of scum, by jetting a facelike air current onto the plane orthogonal to the head axis from the tip of the head when scum floated on the surface of the molten metal is sucked and removed by the suction head. CONSTITUTION:When scum on the surface of the molten metal is sucked and removed by suction head 1, cylindrical outside cylinder 7 is provided at the tip part of cylindrical main body 5 of the head to form annular gas chamber 6. At the tip of chamber 6, nozzle device 10 provided with jetting hole 9 consisting of flange body 8 and tip part 7a is formed in the part brought into contact with tip 5a of suction head 1. When scum is sucked from suction entrance 1a at the tip of the suction head, compressed air is pressed into annular gas chamber 6 from gas supplying tube 12, and facelike air current 13 is formed on the face orthogonal to the axis of cylindrical material 5 of head 1 from jetting hole 9 at the tip. The suction air current to the suction head passes between said air current 13 and the surface of scum to move scum toward suction entrance 1a, and thus, scum is sucked with high efficiency without a wasteful air current.

摘要： PURPOSE:To positively seal a portion between a pipe body of an inlet of an impeller and the impeller, by preventing the infiltration of liquids into the impeller by discharging the liquids penetrating to a void between a front shroud of the impeller and labyrinth packing. CONSTITUTION:When applying this device to a separating device for sucking scum on a surface of molten metal and for separating the scum from air currents sucked, a pipe body 4 continuously mounted to a bottom wall 16 of a negative pressure chamber 1 is immersed under the surface 6 of a liquid tank 5, and the pipe body 4 is faced to an inlet of an impeller 7 consisting of a plurality of vane bodies 10 at a location where the pipe body 4 is stretched. A ringed groove 19 and holes 21 are installed to a front shroud body 8a forming the impeller 7, and the ringed groove 19 is blocked by means of ringed portion material 8b to which a hole 20 is disposed. A sleeve 14, which one end outer surface is provided with a screw portion 14a, and labyrinth packing 15 consisting of a labyrinth ring 16 and a spacer 17, which are externally fitted to the sleeve alternately, are mounted between the pipe body 4 and the front shroud 8, thus obtaining seal action.
