ABSTRACT OF THE DISCLOSURE Filter units for use in filtering liquid suspen-sions of material prone to form a filter cake resistant to continued flow of filtrate therethrough, e.g., wastewater treatment sludge, have a pair of planar sides arranged in a V-shape. Such sides are formed of rigid filter media, e.g., porous sheets of granular material bound in a resin matrix. Suspension to be filtered is charged into the trough and filtrate is drawn by vacuum through its porous sides. A plurality of such units are arranged side-by-side about a common center in a cylindrical assembly which can be rotated about such center at a predetermined rate to permit each unit to pass through a series of filtering steps to provide new filtering methods.

La presente invención se refiere a un filtro de banda de vacío que comprende una banda (1) con una pluralidad de cajas de vacío (2), medios de filtro que están dispuestos en las cajas de vacío, medios de accionamiento (4) para mover la banda (1) y una estación de succión (5) para crear una presión negativa en las cajas de vacío (2) en la estación de succión 5. Con el propósito de permitir la separación líquido-sólido a bajos costos energéticos y un mantenimiento no frecuente del filtro de banda de vacío, el medio de filtro se encuentra en la forma de un filtro capilar, cada caja de vacío (2) está provista de dicho filtro y cada caja de vacío está provista de una salida (8) que tiene una válvula de retención que permite que un fluido fluya desde el espacio interior de la caja de vacío hacia el exterior de la caja de vacío para crear una presión negativa en la caja de vacío cuando la estación de succión (5) está conectada con la caja de vacío, dicha válvula de retención evita que el fluido fluya a través de la válvula de retención hacia el espacio interior de la caja de vacío cuando la caja de vacío sale de la estación de succión (5). La invención se refiere también a un elemento de filtro, a una caja de vacío (2) y a métodos para realizar el mantenimiento del filtro de banda de vacío y a un método para la separación líquida-sólida por medio de un filtro de banda.

Dirt separator for a vacuum cleaner

A dirt separator for a vacuum cleaner includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes. The dirt-laden fluid enters the chamber along a flow axis that intersects the disc.

Handheld vacuum cleaner

A handheld vacuum cleaner includes a dirt separator. The dirt separator includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes.
