Abstract
(A1) Es wird eine Vorrichtung zum Schleuderstrahlen von empfindlichen Strahlmitteln, insbesondere Trockeneis, mit einem rotierenden Schleuderrad, das über den Umfang verteilte Wurfschaufeln aufweist, einer im Mittelbereich des Schleuderrades angeordneten, mit dem Schleuderrad rotierenden Beschleunigungshülse und einer Zufuhrvorrichtung zum Zuführen des Strahlmittels in die Beschleunigungshülse vorgeschlagen. Die Zufuhrvorrichtung weist eine Vorbeschleunigungshülse mit einer solchen Geometrie auf, dass das zuzuführende Strahlmittel neben einer axialen Bewegung zum Schleuderrad radial vorbeschleunigt wird.
EP 1870205 A1 UPAB: 20080310 NOVELTY - The device has a rotary spinner, which exhibits throw shovels (14) that are distributed over the circumference. An acceleration cover (12) rotates with the rotary spinner. A supply or dosing device is provided for supplying the dry ice into the acceleration cover. The supply or dosing device has a pre-acceleration cover (15), and exhibits an inner geometry extending to the throw shovels for axial and radial pre-acceleration of the dry ice at the throw shovel. The acceleration cover is designed as a cylindrical circular body, which is provided with a radial passage opening. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for centrifugal blasting of dry ice. USE - Used for centrifugal blasting of dry ice. Can also be used for blasting rod material, rolled steel products, sheet metal and pliable molded small components of larger number of pieces, and for pre-treatment of plastic and metal components e.g. bumper, vehicle body parts and aircraft casing, in automobile, aerospace and navigation industries, and for cleaning the molds in the casting and food industries and for degreasing the extruded semi-finished product. ADVANTAGE - The acceleration cover is designed as the cylindrical circular body, which is provided with the radial passage opening, thus achieving an increased flow rate of the dry ice, an increased efficiency and reduced investment and operating costs, while processing the dry ice with care.
