Title (EN) BACK FLUSHABLE FILTERS
(FR) FILTRES RINCABLES
Abstract:
(EN) A back flushable filter which has number of separable sections (2) which can be separately accessed and there can be provided a flow pattern so that one of the sections is being back flushed while the other sections are providing normal filtering. Valve means (11) providing for such access can be inched around to select each section in turn. The filtering means can comprise sand or it can comprise a stack of separable segments which provide for inclined gaps between adjacent parts of each adjoining stack element with the convergence and gap size selected to encourage compaction of particles within the converging part of each gap but further selected such that on back flushing such compacted particles can be readily easily disgorged for total cleansing.
(FR) Un filtre rinçable comprend un certain nombre de sections séparables (2) auxquelles on peut accéder séparément et présente un schéma d'écoulement tel qu'une des sections peut être rincée pendant que les autres sections effectuent un filtrage normal. Des soupapes (11) permettant un tel accès peuvent être peu à peu déplacées en cercle afin de sélectionner une section après l'autre. L'organe de filtrage peut comprendre du sable ou être constitué d'une pile de segments séparables délimitant des espaces inclinés entre les parties adjacentes de chaque élément adjacent de la pile, la convergence et la taille des espaces étant sélectionnées de manière d'une part à stimuler le tassement des particules à l'intérieur de la partie convergente de chaque espace et d'autre part à permettre, lors du rinçage, un dégorgement rapide et facile desdites particules tassées afin d'obtenir un assainissement total.
