Abstract

La pâte mécanique formée dans un défibreur sous pression est recueillie dans un réservoir 20 muni d'une évacuation 22 permettant de décharger la pâte mécanique à la pression atmosphérique. La surface de la pâte dans le réservoir est maintenue à un niveau 20a supérieur à ladite évacuation de sorte que la pâte forme un sas à pression dans la communication entre la chambre de défibrage et l'évacuation 23. Une vanne de commande 24 et un détecteur de différence de pression 25 permettent de réguler l'écoulement de la pâte en maintenant un niveau prédéterminé dans le réservoir 20. Application au fonctionnement en continu d'un défibreur sous-pression.
