Abstract

Agitateur à utiliser avec un filtre à disques servant à filtrer un coulis de matières solides et de liquide. Ledit agitateur comporte un conduit d'entrée qui reçoit une quantité de coulis. Une tuyère est connectée au conduit d'entrée de l'agitateur et augmente la vitesse de la quantité de coulis introduite. Un ensemble éjecteur reçoit ce qui sort de la tuyère et prélève une quantité supplémentaire de coulis dans la cuve pour l'introduire dans le tube éjecteur. Ledit ensemble éjecteur dirige la combinaison constituée par le coulis introduit et le coulis de recirculation vers le centre de la cuve. Un agitateur est placé entre chaque disque du filtre.
