Abstract
In a centrifuge, the centrifuge baskets may be conical or cylindrical, and the inner surface of the basket is provided with grooves or a mesh for forming flow-off paths. A screen is supported inside of a centrifugal drum, basket, or cage. The screen may rest on the inner surface of the drum, cage, or basket, or support members may be interposed between the screen, and the drum, basket or cage. In any event, passageways are provided between the screen and the rotating centrifugal member such as a drum, basket or cage. The radially outer surfaces of the screen are at least partially roughened, and corresponding contact areas of the supporting surface are also roughened, in order to increase the friction at said contact areas.
Claims14
In a centrifuge having a rotatable means with liquid flow-off path means on the radially inner surface thereof, and a screen positioned in contact against the radially inner surface of said rotatable means, the improvement comprising a plurality of first roughened surface means on a portion of the radially outwardly facing surface of said screen and a like plurality of second roughened surface means on a corresponding radially inner surface portion of said rotatable means, said first and second roughened surface means contacting each other in a locking manner, thereby providing a frictional resistance under the influence of the centrifugal force, said frictional resistance holding the screen in place substantially uniformly over the entire surface of the screen, whereby relative movement between the screen and the rotatable means is substantially inhibited.
