Abstract

SE DESCRIBE UN APARATO PARA SEPARAR SOLIDOS SUSPENDIDOS EN PASTA AGUADA LIQUIDA PRESURIZADA ENTRANTE. EL APARATO COMPRENDE UN RECIPIENTE QUE TIENE UNA PARED DE RECIPIENTE CILINDRICA ALARGADA, UN EXTREMO SUPERIOR CERRADO Y UNA SECCION INFERIOR PARA ACUMULACION DE SOLIDOS. EL RECIPIENTE INCLUYE UN AGITADOR MONTADO PARA ROTACION A LO LARGO DE UNA SUPERFICIE INTERIOR DE LA SECCION INFERIOR Y UNA TURBINA DE DESCARGA MONTADA DEBAJO DE LA SECCION INFERIOR QUE INCLUYE AL MENOS UNA APERTURA. UNA BOMBA DE CORRIENTE DE FONDO ESTA PROVISTA PARA DESCARGAR SOLIDOS SEPARADOS SIN PERDIDA DE PRESION EN EL APARATO. EL APARATO INCLUYE ADEMAS ELEMENTOS PARA DETECTAR NIVEL DE SOLIDOS EN EL APARATO, QUE PREFERIBLEMENTE FUNCIONA SIN ALTERAR EL ESTABLECIMIENTO DE LOS SOLIDOS EN EL MISMO. ADEMAS EL APARATO INCLUYE UN POZO DE ALIMENTACION PARA RECIBIR UNA CORRIENTE DE PASTA AGUADA PRESURIZADA ENTRANTE, TENIENDO EL POZO DE ALIMENTACION UNA APERTURA, UNA DISTANCIA PREDETERMINADA ENCIMA DE UN NIVEL EN EL APARATO DEFINIDO POR SOLIDOS ESTABLECIDOS.
