Title (EN) METHOD AND APPARATUS FOR CLEANING OF A FILTER PLATE
(FR) PROCEDE ET DISPOSITIF DE NETTOYAGE D'UNE PLAQUE FILTRANTE
Abstract: front page image
(EN)The invention relates to a method and assembly for cleaning a disc sector in a disc filter. After the disc sector (2) has left the discharge chute during the rotation of the disc and become again immersed into the slurry, the sector is internally subjected via a suction pipe (3) to a positive pressure not lower than the atmospheric pressure while the sector is simultaneously subjected to ultrasonic vibration (29) directed perpendicular to the surface of the sector.
(FR)L'invention concerne un procédé et un dispositif de nettoyage d'une section annulaire d'un disque filtrant. Lorsque la section annulaire (2) a quitté la goulotte de décharge pendant la rotation du disque et est à nouveau immergée dans la suspension, ladite section est soumise de façon interne à une pression positive supérieure à la pression atmosphérique, par l'intermédiaire d'une tubulure d'aspiration (3), et soumise simultanément à une vibration ultrasonique (29) perpendiculaire à la surface de ladite section.
