Abstract

La présente invention a trait à un appareil comprenant une trémie principale ayant une configuration de nettoyage de surface et une configuration de sablage-salage. Dans la configuration de nettoyage de surface, la trémie principale est dotée d'une entrée d'écoulement d'air chargé de débris, d'une sortie d'écoulement d'air et d'une sortie de décharge de débris et est pratiquement hermétique au milieu ambiant différent de l'entrée d'écoulement d'air chargé de débris et de la sortie d'écoulement d'air. Dans la configuration de sablage-salage, la trémie principale est dotée d'une entrée de réception de sable et de sel et d'une sortie de sable et de sel. Pendant son utilisation et lorsque la trémie principale est dans la configuration de nettoyage de surface, pratiquement tout l'air chargé de débris entre dans la trémie principale par l'entrée d'écoulement d'air chargé de débris, pratiquement tout l'air sort de la trémie principale par la sortie d'écoulement d'air et pratiquement tous les débris sortent de la trémie principale par la sortie de décharge des débris. Pendant son utilisation et lorsque la trémie principale est dans la configuration de sablage-salage, pratiquement tout le sable et le sel entrent dans la trémie principale par l'entrée de réception du sable et du sel et pratiquement tout le sable et le sel sortent de la trémie principale par la sortie du sable et du sel.
