<p>971,658. Gravity-separation apparatus. J. MULLER. May 30, 1962 [Aug. 22, 1961], No. 20842/62. Heading B1D. Apparatus for separating a light substance, e.g. oil or particles of solid matter, mixed with or suspended in a liquid of greater density, e.g. water, comprises a floating separator (Fig. 1) including a diffuser 1 and suction bell 9. The diffuser comprises a dish 2, a diffusing element 6, e.g. a sprinkler rose, floats 5 attached to the element 6, and a tube 3 slidably engaging with a vertical pipe 4 fixed to the bottom of a tank 13 (Fig. 2). The suction bell is divided by partitions 21 into a plurality of annular sections, and is attached to a suction pipe 10 pivotally mounted on a ball joint 15 and carrying a counterweight 16. The bell is supported by a float 11 attached thereto by a central perforated tube or vertical bars. The mixture or suspension is stored in a reservoir 20 coupled to the pipe 4, the light substance being dispersed by the diffuser to form a layer 8 which is drawn off through the suction bell. The more dense liquid flows through a pipe 17 and a tank 14 before it is discharged through an overflow pipe 18. The pipe 10 delivers the lighter substance to apparatus (not shown) in which final separation is performed. A further floating separator, similar to that shown in Fig. 1, may be lodged in the tank 14.</p> |
