Title
(EN) FEED DISTRIBUTION AND CONTROL ARRANGEMENT FOR CENTRIFUGE
(FR) DISTRIBUTION D'ALIMENTATION ET INSTALLATION DE REGULATION POUR SEPARATEUR CENTRIFUGE
Abstract
(EN)
A tube (100) feeds a solid/liquid mixture (130) to the centre of a rotating perforated centrifuge basket (10) having a central cylindrical portion (40). Control of the feed is provided by moving the tube (100) vertically so that an annular gap (120) is formed in the region (50) between the conical end (60) and tube (100). The central member including end (60) to which is attached a cylindrical extension (not numbered) is stationary. Tube (100) is of such a diameter that when completely lowered it closes the gap (120). Member and end (60) may be hollow to allow introduction of steam, water, or other fluids into the region (50) for the purpose of heating or lubrication. The invention relates particularly to centrifuging massecuite.
(FR)
Un tube (100) alimente en un mélange solide/liquide (130) le centre d'un bol perforé rotatif (10) d'un séparateur centrifuge, qui comprend une partie centrale cylindrique (40). On régule l'alimentation en déplaçant le tube (100) verticalement de sorte qu'un espace annulaire (120) est produit dans la région (50) située entre l'extrémité conique (60) et le tube (100). L'élément central comprenant l'extrémité (60) à laquelle est fixé un prolongement cylindrique (sans numéro) est immobile. Le tube (100) présente un diamètre tel que, lorsqu'il est complètement abaissé, il ferme l'espace (120). L'élément et l'extrémité (60) peuvent être creux afin de permettre l'introduction, dans la région (50) de vapeur, d'eau ou d'autres fluides destinés au chauffage ou à la lubrification. L'invention se rapporte particulièrement à la centrifugation de la masse cuite.
