Title
(EN) PRESSURE FILTER
(FR) FILTRE SOUS PRESSION
Abstract
(EN) The present disclosure 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. A displacement sensor is provided to measure the displacement of a lower pressing plate before, during and after pressurisation of the filter chambers. If the change in displacement during or after pressurisation exceeds a threshold, an alarm or notification is provided.
(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 également connus sous le nom de presses à tour. Un capteur de déplacement est prévu pour mesurer le déplacement d'une plaque de pression inférieure avant, pendant et après la mise sous pression des chambres de filtration. Si le changement de déplacement pendant ou après la mise sous pression dépasse un seuil, une alarme ou une notification est fournie.
