Abstract
L'invention concerne un mélangeur à écoulement longitudinal et plus particulièrement un mélangeur de liquides visqueux. Ce mélangeur comporte un boîtier (10) présentant une entrée d'extrémité (12a, 14a) pouvant être reliée à une source mise sous pression de liquides et une ouverture (119) se trouvant à l'extrémité opposée du boîtier (10). Un mandrin (30) placé dans la cavité présente des protubérances (20', 32') ayant des surfaces latérales en pente dont les bords extérieurs coopèrent avec la surface (114a) intérieure de la cavité pour diviser la cavité en une série de chambres séparées par des fentes, de manière qu'un liquide passe successivement à travers toutes les chambres et fentes en se déplaçant de l'entrée (12a, 14a) vers la sortie (119). Les fentes présentent des coupes transversales qui diminuent dans le sens d'écoulement du liquide. Les côtés du mandrin (30) présentent des rainures (134) hélicoïdales formant des passages avec la paroi (114a) du boîtier qui permettent une distribution uniforme du liquide autour des bords du mandrin (30) vers l'extrémité d'entrée ou la chambre en amont. Le mandrin (30) peut pivoter de manière à assurer un mélange supplémentaire par cisaillement.
