Abstract
An improved screen basket for use with a centrifuge includes two adjoining screen sections. The first screen section is formed from a wear resistant material and is located proximate to the point at which slurry is introduced into the basket. The length of the first screen section is chosen so that the majority of potential wear caused by the abrasive slurry occurs within the first section of the basket. The second screen section is preferably formed from less expensive materials, such as steel wedge wire. The second screen section smoothly joins the first screen section and provides for further dewatering or separation of the accelerated slurry so that a dry cake is produced by the centrifuge.
Claims9
A vibrating centrifuge for use in separating a solids-liquid slurry, the vibrating centrifuge comprising:
- A. a basket rotatably mounted within the centrifuge, the basket having a first end, a second end, an inner surface and a plurality of apertures and comprising:
- a first section disposed proximate to the first end, at least a portion of the first section formed from a plurality of wear resistant elements configured and arranged within the first section so as to define a plurality of slots in fluid communication with respective ones of the apertures;
- and
- a second section disposed proximate to the second end and joining the first section, the second section formed from a plurality of wire members configured and arranged within the second section so as to define a plurality of channels in fluid communication with respective ones of the apertures;
- B. means for rotating the basket about an axis;
- C. means for vibrating the basket;
- and
- D. means for feeding the solid-liquid slurry to the centrifuge so that the slurry enters the basket at the first section,
- wherein the liquid portion of the slurry passes through the slots of the first section and the channels of the second section and the solids portion is retained on the inner surface of the basket and is conveyed toward the second end in response to the vibrating means.
