Title:
SURFACE LAYER LIQUID DISCHARGE APPARATUS
Document Type and Number:
Japanese Patent JP3218307
Kind Code:
B2
Abstract:
PURPOSE: To provide the apparatus capable of efficiently introducing a surface layer liquid into a liquid sump from the entire periphery of the upper edge of a weir plate.
CONSTITUTION: One end part of a flexible member 22 such as a bellows cylinder is fixed to the outer peripheral part of the substrate 1 provided in a liquid and the other end part thereof is fixed to the outer periphery of the weir plate 20 provided to the outer periphery of a float main body 4 and a liquid sump 5 is formed in the state surrounded by the substrate 1, the flexible member 2 and the float main body 4. The float main body 4 floats and sinks corresponding to the liquid amt. in the liquid sump 5 and, at the time of sinking, a surface layer liquid flows in the liquid sump 5 from the entire periphery of the upper edge of the weir plate 20 and the inflow ratio of a liquid other than the surface layer liquid to the liquid sump 5 is reduced and the surface layer liquid can be efficiently discharged to the outside from the liquid sump 5 by a liquid discharge pipe 13.
