Abstract

QUE COMPRENDE: 1) UN RECIPIENTE QUE RECIBE UNA SUSPENSION DE LIQUIDOS CON MATERIAL SOLIDO PARTICULADO SUSPENDIDO, LA PORCION SUPERIOR DE (1) MANTIENE UNA ZONA DE SEDIMENTACION LIBRE CON UNA CONCENTRACION BAJA DE PARTICULAS SOLIDAS SUSPENDIDAS, LA PORCION INFERIOR MANTIENE UNA ZONA DE COMPACTACION CON UNA CONCENTRACION ALTA DE MATERIAL PARTICULADO SOLIDO SUSPENDIDO Y UNA ZONA DE SEDIMENTACION LIMITADA ENTRE LA ZONA DE COMPACTACION Y LA ZONA DE SEDIMENTACION, QUE CONFORMA LAS ZONAS DE SEDIMENTACION INFERIORES; 2) UN CANALIZO DE REBOSE ADYACENTE AL EXTREMO SUPERIOR DE (1) QUE DESCARGA LA FASE DE REBOSE DE LA SUSPENSION QUE HA SIDO SEPARADA EN (1); 3) UN ORIFICIO DE DESCARGA PARA LA CORRIENTE DERIVADA AL FONDO DE (1) PARA SEPARAR UNA FASE ESPESADA DE DICHA CORRIENTE SEPARADA DE (1); 4) UN ELEMENTO DE DELICUEFACCION PARA EL FLUJO DEL LIQUIDO QUE SE EXTIENDE DESDE LA PORCION INFERIOR DE (1) HACIA SU PORCION SUPERIOR; Y 5) UN MONTAJE DE RASTRILLO QUE GIRA EN LA PORCION INFERIOR DE (1), EL CUAL TIENE UNA ESTACA ALARGADA VERTICAL QUE FORMA CANALES EN LA SUSPENSION PARA LIBERAR EL LIQUIDO EN UNA DE LAS ZONAS DE SEDIMENTACION INFERIORES QUE VA HACIA (4). UN METODO DE OPERACION QUE COMPRENDE ALIMENTAR UNA SUSPENSION EN UN LIQUIDO EN (1); SEPARAR LA SUSPENSION POR GRAVEDAD; DESCARGAR UNA FASE DE REBOSE Y UNA FASE ESPESADAWHICH INCLUDES: 1) A VESSEL RECEIVING A SUSPENSION OF LIQUIDS WITH SUSPENDED PARTICULATE SOLID MATERIAL, THE UPPER PORTION OF (1) KEEPING A FREE SEDIMENTATION ZONE WITH A LOW CONCENTRATION OF SUSPENDED SOLID PARTICLES, THE LOWER PORTION OF A CONNECTING ZONE COMPACT. A HIGH CONCENTRATION OF SUSPENDED SOLID PARTICULATE MATERIAL AND A LIMITED SEDIMENTATION ZONE BETWEEN THE COMPACTION ZONE AND THE SEDIMENTATION ZONE, WHICH MAKES UP THE LOWER SEDIMENTATION ZONES; 2) AN OVERFLOW CHANNEL ADJACENT TO THE UPPER END OF (1) WHICH DISCHARGES THE OVERFLOW PHASE OF THE SUSPENSION WHICH HAS BEEN SEPARATED IN (1); 3) A DISCHARGE ORIFICE FOR THE CURRENT DERIVED AT THE BOTTOM OF (1) TO SEPARATE A THICKENED PHASE OF SAID CURRENT SEPARATED FROM (1); 4) AN ELEMENT OF DELICUEFACTION FOR THE FLOW OF LIQUID THAT EXTENDS FROM THE LOWER PORTION OF (1) TOWARDS ITS UPPER PORTION; AND 5) A ROTATING RAKE ASSEMBLY IN THE LOWER PORTION OF (1), WHICH HAS A VERTICAL ELONGATED STAKE THAT FORMS CHANNELS IN THE SUSPENSION TO RELEASE THE LIQUID IN ONE OF THE LOWER SEDIMENTATION ZONES GOING TOWARDS (4). A METHOD OF OPERATION THAT INCLUDES FEEDING A SUSPENSION IN A LIQUID IN (1); SEPARATE THE SUSPENSION BY GRAVITY; UNLOADING AN OVERFLOW PHASE AND A THICKENED PHASE
