FLUID FILTER WITH ENHANCED BACKFLUSH FLOW
A backflush conduit (38) for an automatic backflushing filter (10) having an inlet portion (62) with a symmetrical converging bell-shaped cross section, an outlet portion (60) with a generally cylindrical shape, and a converging and reorienting transition portion (64) connecting the inlet and outlet...

| description | A backflush conduit (38) for an automatic backflushing filter (10) having an inlet portion (62) with a symmetrical converging bell-shaped cross section, an outlet portion (60) with a generally cylindrical shape, and a converging and reorienting transition portion (64) connecting the inlet and outlet portions. Converging convex surfaces (66, 68) of the bell-shaped opening (62) smooth fluid inflow and prevent fluid separation. The transition portion (64) interior contour redirects the fluid flow without inducing turbulence, resulting in more efficient backflushing to clean the entire filter element (26) even at small element pore sizes.
Cette invention concerne un conduit de circulation inverse (38) pour filtre à contre-lavage automatique(10), lequel conduit comprend une partie admission (62) ayant une section symétrique convergente en forme de cloche, ainsi qu'une partie sortie (60) ayant une forme générale cylindrique, une partie de transition convergente et de réorientation (64) reliant lesdites parties admission et sortie. Les surfaces convexes convergentes (66, 68) de l'ouverture en forme de cloche (62) stabilisent le débit d'entrée des fluides et empêchent leur séparation. Le contour interne de la partie de transition (64) réoriente l'écoulement du fluide sans engendrer de turbulences, ce qui permet d'obtenir un contre-lavage plus efficace permettant de nettoyer l'élément filtre (26) tout entier, même lorsque les pores de l'élément sont de taille réduite. |
