Abstract

L'invention concerne un appareil de désagrégation de papier et de carton se composant d'une cuve 1, ouverte en haut, dans laquelle la matière à désagréger est introduite, par exemple en provenance d'une machine à papier placée au-dessus de l'appareil, et à partir de laquelle la matière désagrégée est évacuée au moyen d'une pompe, l'appareil comprenant au moins deux unités de désagrégation 6, de préférence des rotors tournants, qui sont placés sur une paroi de la cuve 1 ; les dispositifs de désagrégation utilisés à l'heure actuelle présentent l'inconvénient de ne pas laisser suffisamment d'espace pour la pompe évacuant la masse désagrégée et que les rotors sont placés dans une position ne permettant pas une utilisation efficace de l'énergie d'écoulement, ce qui se traduit par une grande consommation d'énergie ; ce problème est résolu en ce que les lignes droites correspondant aux axes des arbres des rotors 3 se recoupent au moins dans un prolongement. (CF DESSIN DANS BOPI)The invention relates to an apparatus for disintegrating paper and cardboard, consisting of a tank 1, open at the top, into which the material to be disintegrated is introduced, for example from a paper machine placed above the tank. apparatus, and from which the disintegrated material is discharged by means of a pump, the apparatus comprising at least two disintegration units 6, preferably rotary rotors, which are placed on a wall of the vessel 1; the disintegration devices used at present have the drawback of not leaving sufficient space for the pump removing the disintegrated mass and that the rotors are placed in a position which does not allow efficient use of the energy of flow, which results in high energy consumption; this problem is solved in that the straight lines corresponding to the axes of the shafts of the rotors 3 intersect at least in an extension.
