Title (EN) VESSEL SCREEN RETAINING SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE RETENUE DE GRILLE DE RÉCIPIENT
Abstract:
(EN) Certain embodiments include a screen assembly of a vessel, where the screen assembly includes a plurality of fixed elements and a retainer, and the retainer includes a ring, a plurality of wedges disposed about the ring, and a plurality of keyholes at spaced locations about the ring. Each keyhole includes a bore and a slot extending from the bore into an adjacent wedge of the plurality of wedges, the slots have a width less than the bores, and the retainer may receive the fixed elements through the bores and may be rotated in a relation with the plurality of fixed elements to bring the plurality of fixed elements into simultaneous engagement with the wedges.
(FR) Certains modes de réalisation comprennent un ensemble grille d'un récipient, l'ensemble grille comprenant une pluralité d'éléments fixes et un dispositif de retenue, et le dispositif de retenue comprenant un anneau, une pluralité de cales disposées autour de l'anneau, et une pluralité de boutonnières à des emplacements espacés autour de l'anneau. Chaque boutonnière comprend un alésage et une fente s'étendant à partir de l'alésage dans une cale adjacente parmi la pluralité de cales, les fentes ont une largeur inférieure à celle des alésages, et le dispositif de retenue peut recevoir les éléments fixes à travers les alésages et peut être tourné dans une relation avec la pluralité d'éléments fixes pour amener la pluralité d'éléments fixes en prise simultanée avec les cales.
