Title (EN) DEVICE FOR REPEATEDLY AND AUTOMATICALLY DETERMINING THE DEHYDRATING POWER OF A FIBRE MATIERIAL SUSPENSION
(FR) DISPOSITIF POUR DETERMINER DE FACON REPETITIVE ET AUTOMATIQUE LE POUVOIR DESHYDRATANT D"UNE SUSPENSION DE MATIERE FIBREUSE
Abstract: front page image
(EN)This device employed for example in the paper manufacturing, is used to adjust directly the reaction process. Such devices must have a good response to the behaviour of the fibre material in the paper machine, a reduced maintenance time and a failure-free operator. This device comprises a flow pipe (12) closed at its lower end by a wire sieve (13) and which may tilt about a horizontal axis (36) in a vertical plane. Hence, either the upper opening (14) thereof may be aliyned with a product input (8), or the lower sieve (13) may be brought under a washing device (40). The pipe (12) is filled up to the overflow (15) with a product sample and it is cause to flow through the sieve (13). The amount of filtrate collected in a measuring beaker (27) during a predetermined time interval (after a previous flowing period) is the value searched for.
(FR)Ce dispositif utilise par exemple dans la fabrication de papier, sert a regler directement le processus reactionnel. De tels dispositifs doivent comporter une bonne reponse au comportement de la matiere fibreuse dans la machine a papier, un entretien fortement reduit et un fonctionnement exempt de pannes. Ce dispositif comprend un tuyau d"ecoulement (12) ferme a son extremite inferieure par un tamis metallique (13) et qui peut basculer autour d"un axe horizontal (36) dans un plan vertical. Ainsi, on peut soit aligner son ouverture superieure (14) avec une entree de produit (8), soit amener son tamis inferieur (13) sous un dispositif de lavage (40). On remplit le tuyau (12) jusqu"au trop-plein (15) avec un echantillon de produit et on le fait ecouler a travers le tamis (13). La quantite de filtrat recueilli dans un becher de mesure (27) pendant un intervalle de temps determine (apres une periode d"ecoulement prealable) constitue la valeur cherchee.
