Abstract

Centrifugeuse à vis sans fin à bol plein comportant une partie d'enveloppe cylindrique de clarification et une partie d'enveloppe d'allure conique pour l'évacuation des matières solides, ainsi qu'une vis sans fin d'entraînement de forme conique et cylindrique, disposée coaxialement dans cette dernière partie d'enveloppe, une chicane étant disposée sur le corps de vis dans la zone de transition entre la partie cylindrique et la partie conique de l'enveloppe et des orifices séparés de sortie pour le liquide et pour les matières solides étant prévus dans la partie d'enveloppe cylindrique et la partie d'enveloppe conique. Il est prévu sur le corps de vis et/ou sur la partie conique du tambour de la centrifugeuse, des organes déflecteurs de liquide qui communiquent - vu dans la direction de l'évacuation des matières solides - avec la zone des matières solides à évacuer en arrière de la chicane. Application à l'épuration des eaux d'égout.
