Title
(EN) FILTRATION SYSTEM FOR USE IN A SHALE SHAKER
(FR) SYSTÈME DE FILTRATION DESTINÉ À ÊTRE UTILISÉ DANS UN TAMIS VIBRANT
Abstract
(EN)
Shale shaker filtration system including a filtration component (2), a positioning component (3), and a frame (5), wherein the filtration component (2) includes at least one screen (21) having one or more layers of a sieving material, the positioning component (3) includes one or more first connecting members (31) and one or more second connecting members (32), and the frame (5) is sub-divided into a plurality of units (6) having openings (4); and wherein each positioning component (3) is disposed at least partially within a frame unit opening (4) and is reversibly engaged with the frame via the second connecting member(s) (32), and each filtration component (2) is disposed on top of a positioning component (3) and is reversibly engaged therewith via the first connecting member(s) (31).
(FR)
L'invention concerne un système de filtration de tamis vibrant comprenant un composant de filtration (2), un composant de positionnement (3) et un cadre (5), le composant de filtration (2) comprenant au moins un crible (21) pourvu d'au moins une couche d'un matériau de criblage, le composant de positionnement (3) comprenant au moins un premier élément de liaison (31) et au moins un deuxième élément de liaison (32), et le cadre (5) étant sous-divisé en une pluralité d'unités (6) comportant des ouvertures (4) ; et chaque composant de positionnement (3) étant disposé au moins partiellement à l'intérieur d'une ouverture d'unité de cadre (4) et étant mis en prise de façon réversible avec le cadre par l'intermédiaire du/des deuxième(s) élément(s) de liaison (32), et chaque composant de filtration (2) étant disposé au sommet d'un composant de positionnement (3) et étant en prise réversible avec ce dernier par l'intermédiaire du/des premier(s) élément(s) de liaison (31).
