Abstract

Procédé et appareil de nettoyage de fragments ou copeaux de matière plastique encrassés. Les copeaux sont introduits dans le liquide d'une cuve et un arbre à agitateurs les fait remonter le long d'un tamis incliné jusqu'à une vis montée sur cet arbre au-dessus du niveau du liquide et surmontée d'injecteurs qui rincent ces copeaux. La vis fait tomber ces derniers dans un récipient dans lequel du liquide circulant de bas en haut les fait surnager, et les amène à un tambour perforé quie les repousse hors de l'appareil. Application au nettoyage des copeaux de matière plastique trop denses pour pouvoir rester en suspension dans un liquide.Method and apparatus for cleaning contaminated plastic fragments or chips. The chips are introduced into the liquid of a tank and a stirrer shaft brings them up along an inclined sieve to a screw mounted on this shaft above the level of the liquid and surmounted by injectors which rinse these shavings. The screw drops the latter into a container in which the liquid flowing from the bottom to the top makes them float, and brings them to a perforated drum which pushes them out of the apparatus. Application to the cleaning of too dense plastic shavings to be able to remain in suspension in a liquid.
