Title
(EN) COMBINED SCREW FOR WATER PROCESSING APPARATUSES
(FR) VIS COMBINEE POUR APPAREILS DE TRAITEMENT DES EAUX
Abstract
(EN)
The invention describes a screw for a water treatment apparatus, such as an aerator or mixer, said apparatus comprising a power source (1) driving a shaft (2) on which is fitted a screw that sucks the water up or impels it downward. The screw consists of a helicoidal, spiral-shaped screw blade construction round said shaft, with an upper end part (A), a lower end part (C) and a middle part (B) between said two end parts, with at least one of said end parts comprising an extra screw blade.
(FR)
L'invention concerne une vis pour un appareil de traitement des eaux tel qu'un dégazeur ou un mélangeur qui comporte une alimentation (1) entraînant un arbre (2) sur lequel est montée une vis qui aspire l'eau vers le haut ou la propulse vers le bas. La vis consiste en une structure à pales d'hélice disposée en spirale autour dudit arbre et présentant une partie d'extrémité supérieure (A), une partie d'extrémité inférieure (C) et une partie médiane (B) entre les deux, au moins une desdites parties d'extrémité comprenant une pale d'hélice supplémentaire.
