Abstract

Eine Mischvorrichtung für Trockenstoffe, insbesondere zum Mischen und Abkühlen von Kunststoffen, in deren etwa zylindrischem Mischbehälter (1) zentrisch eine Rührwerks­ welle (5) mit Mischflügeln (7), von einem Motor antreibbar angeordnet ist. Das technische Problem betrifft die automati­ sche Reinigung ohne Ausbau der Mischwerkzeuge oder Öffnen des Deckels. An den Mischflügeln (7) sind Luftleitun­ gen (9) angeordnet, die an einen Luftkanal (8) der Rührwerks­ welle (5) angeschlossen sind und zu den Mischflügelenden reichen. Die Luftleitungen (9) führen zu Düsenmundungen (10, 13), die auf die Behälterwandung, Bodenwandung, den Deckel sowie die Wände etwaiger Kühleinsätze ausgerichtet sind. A mixing device for dry substances, in particular for mixing and cooling plastics, in about cylindrical mixing container (1) centrally an agitator shaft (5) with mixing blades (7), can be driven by a motor is arranged. The technical problem concerns the automati cleaning without removing the mixing tools or Open the lid. On the mixing blades (7) are air duct gene (9) arranged on an air duct (8) of the agitator shaft (5) are connected and to the mixing blade ends pass. The air lines (9) lead to nozzle mouths (10, 13) on the container wall, bottom wall, the Cover and the walls of any cooling inserts aligned are.
