Abrégé
(EN)
An Archimedes screw plant (10) for separating slurry. The plant (10) comprises: - a tubular sifting device (11); - a slurry feeding device (31); - a device (21) for evacuating the liquid fraction; - a device (19, 22) for evacuating the substantially dry separated solid. The device (11) comprises an upper compaction chamber (19) of the separated solid where a solid plug of product is formed. In addition, the tubular sifting device (11) has an upper opening (22) being provided with an auxiliary contrast element (40) for forming said solid plug of product.
(FR)
La présente invention se rapporte à une installation à vis d'Archimède (10) destinée à séparer une suspension. L'installation (10) comprend : - un dispositif de tamisage tubulaire (11) ; - un dispositif d'acheminement de suspension (31) ; - un dispositif (21) destiné à évacuer la fraction liquide ; - un dispositif (19, 22) destiné à évacuer le solide séparé sensiblement sec. L'installation (10) se caractérise en ce que le dispositif (11) comprend une chambre de compactage supérieure (19) du solide séparé où un bouchon de produit solide est formé. De plus, le dispositif de tamisage tubulaire (11) comporte une ouverture supérieure (22) pourvue d'un élément de contraste auxiliaire (40) pour former ledit bouchon de produit solide.
