Since the walls move in opposite directions to each other when they are squeezed together, this zone leads to a mixture of the two components.
  • the finished mixture comes out at the end, which is free of air bubbles and can be filled immediately.
  • the rotation of the hose is preferably carried out by an external drive, in which the pinch rollers deliver the drive from the outside, since the internal frictional forces have to be overcome, and the hose can also be driven in a rotating manner.

Abstract

L'invention concerne un mélangeur tubulaire (100) destiné à mélanger des masses pâteuses ou des liquides contenant au moins deux constituants, avec des constituants pulvérulents liquides ou solides. Ledit mélangeur est notamment destiné à la fabrication de mastic prêt à l'emploi contenant un constituant de mastic (A) et un constituant durcisseur (B) pour la réparation de surfaces de carrosseries automobiles. Ledit mélangeur tubulaire est composé d'un tube (10) disposé verticalement dans un boîtier, réalisé dans un matériau flexible présentant une rigidité propre, ledit tube comportant une ouverture d'entrée supérieure (10a) destinée au constituant à mélanger et une ouverture de sortie inférieure (10b) destinée au mélange. Selon l'invention, a) des cylindres ou rouleaux de compression (20, 21) entraînés périphériquement, comprimés contre une paroi de tube au moyen d'une force élastique permettent de comprimer le tube depuis l'extérieur, et d'entraîner périphériquement ce dernier autour de son axe longitudinal, et b) des cylindres ou rouleaux de compression (20, 21) logés en saillie, comprimés contre une paroi de tube au moyen d'une force élastique permettent de comprimer le tube depuis l'extérieur, et d'entraîner périphériquement ce dernier autour de son axe longitudinal, de manière à former une fente de mélange (MS) dans la zone la plus étroite du tube, dans le sens longitudinal du tube (10), et que les constituants (A, B) soient mélangés sur la paroi intérieure du tube (10) sous l'effet du frottement ainsi créé et des adhérences associées.
