Abstract

Se proporciona un dispositivo para la separacion de líquidos / solidos en el que una cámara de alimentacion tubular se extiende verticalmente hacia abajodentro de un recipiente. La cámara de alimentacion está abierta en su extremo inferior, que estáubicado bien por encima de una entrada central en el fondo delrecipiente para proporcionar una zona compactada de solidos deshidratados ubicada debajo del extremo inferior de la cámara de alimentacion. Un rastrillomezclador ahorquillado habitualmentesemicircular está ubicado dentro de la cámara de alimentacion y un aro de deshidratacion está ubicado alrededor delextremo inferior de la cámara de alimentacion. Una entrada a la cámara de alimentacion en la region superior orienta el lodo de entrada en direccioncircunferencial, haciendo convenientemente que el tubo de entrada siga una trayectoria tangencial o la trayectoria de una curva envolvente, en relacion a lacámara de alimentacion tubular. También se proporcionan medios para introducir líquido clarificado desde la region superior del recipiente hacia el lodo deentrada. El material de gruesos de decantacion espesado se extrae desde la base del recipiente a través de una manga y el líquido clarificado sale desde laparte superior del recipiente.A device for separating liquids / solids is provided in which a tubular feeding chamber extends vertically downwardly within a container. The feeding chamber is open at its lower end, which is located well above a central inlet at the bottom of the container to provide a compacted area of dehydrated solids located below the lower end of the feeding chamber. A usually semicircular bracketing mixer is located inside the feeding chamber and a dehydration ring is located around the lower end of the feeding chamber. An inlet to the feed chamber in the upper region orients the sludge in the circumferential direction, conveniently causing the inlet pipe to follow a tangential path or the path of an enveloping curve, in relation to the tubular feed chamber. Means are also provided for introducing clarified liquid from the upper region of the container into the inlet sludge. The thick material of thickened decantation is extracted from the base of the container through a sleeve and the clarified liquid exits from the upper part of the container.
