Abstract

L'invention concerne une plaque de base pour un filet de criblage non plat (4), une caisse de criblage adoptant la plaque de base, et un dispositif de criblage vibratoire. La plaque de base comprend un corps principal de plaque de base (1). Un élément de support (2) est disposé au niveau du corps principal de plaque de base (1). Un trou traversant de décharge de liquide (3) est disposé au niveau de l'élément de support (2). L'élément de support (2) est utilisé pour supporter une partie non plate d'un filet de criblage non plat (4). L'élément de support (2) au niveau du corps principal de plaque de base (1) augmente une zone de contact entre le corps principal de plaque de base (1) et le filet de criblage non plat (4), de telle sorte qu'une force de liaison entre le corps principal de plaque de base (1) et le filet de criblage non plat (4) soit augmentée, empêchant ainsi le filet de criblage non plat (4) d'être séparé du corps principal de plaque de base (1) et endommagé facilement, et d'augmenter la durée de vie de celui-ci.
