This invention relates to a device for a continuously operated dilution of a slurry sample, through which device the slurry sample is fed directly into a continuously operated optical analyzer, such as a grain size analyzer. The device comprises elements for feeding the slurry sample, elements for feeding diluting liquid and elements for removing solids contained in the slurry, as well as elements for discharging both the liquid contained in the slurry and the liquid used for dilution. The device of the invention comprises at least one downwardly narrowing chamber (2,31) that is connected to the analyzer measurement cell (3, 34) so that two opposite walls (10, 32) of the chamber (2, 31) are essentially parallel both with respect to each other and with respect to the respective walls (21, 35) of the measurement cell (3, 34).
L'invention concerne un dispositif pour diluer en continu un échantillon de suspension épaisse. Selon l'invention, l'échantillon de suspension épaisse est acheminé directement dans un analyseur optique fonctionnant en continu, par exemple un dispositif d'analyse granulométrique. Le dispositif selon l'invention comprend des éléments servant à acheminer l'échantillon de suspension épaisse, des éléments servant à acheminer le liquide pour la dilution et des éléments servant à retirer les matières solides contenues dans la suspension épaisse, ainsi que des éléments servant à évacuer le liquide contenu dans la suspension épaisse et le liquide utilisé pour la dilution. Le dispositif selon l'invention comprend au moins une chambre (2,31), se rétrécissant vers le bas, raccordée à la cellule de mesure d'analyseur (3, 34), de sorte que deux parois opposées (10, 32) de la chambre (2,31) soient pratiquement parallèles l'une à l'autre et parallèles aux parois respectives (21, 35) de la cellule de mesure (3, 34).
