Title
(EN) PRESSURE FILTER
(FR) FILTRE SOUS PRESSION
Abstract
(EN) The present invention relates to pressure filters, and more particularly to horizontal plate pressure filters, in which filter chambers are formed between horizontally extending superimposed filter plates. Such filters are also known as tower presses. At least one moveable pressing plate arranged above or below the filter plates comprises an inclinometer which measures the inclination of the pressing plate during movement. An alarm is activated if the inclination exceeds a threshold in order to prevent damage to the system.
(FR) La présente invention concerne des filtres sous pression, et plus particulièrement des filtres sous pression à plaques horizontales, dans lesquels des chambres de filtration sont formées entre des plaques filtrantes superposées s'étendant horizontalement. De tels filtres sont aussi connus sous le nom de presses à tour. Au moins une plaque de pressage mobile disposée au-dessus ou au-dessous des plaques filtrantes comprend un inclinomètre qui mesure l'inclinaison de la plaque de pressage pendant le déplacement. Une alarme est activée si l'inclinaison dépasse un seuil afin d'empêcher un endommagement du système.
