Abstract

Ice particles are produced from carbon dioxide in the form of ice pellets or scraped from ice blocks. The ice particles are supplied from a reservoir to a processing area through a roller (9) followed by an elevator conveyor (8). A reversible hood provided above the roller to guide the supplied ice particles is adjustable between two flap positions.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Eisstrahlen zur Reinigung von Bauteilen, wobei mittels Kohlenstoffdioxyd Eispartikel in Form von Eispellets bzw. geschabtem Eis aus Blöcken herstellbar sind und aus einem Behälter über ein Strahlsystem auf eine Bearbeitungsfläche aufgebracht werden, wobei die hergestellten Eispartikel über eine zwischengeschaltete Mahlvorrichtung in Form von Walzen auf eine Korngröße im Bereich von etwa 0,5 bis 1,5 mm zerkleinerbar sind und über eine nachgeschaltete Fördereinrichtung einem Strahlsystem zuführbar sind nach Patentanmeldung 101 63 852.3.The invention relates to a Device for ice blasting for cleaning components, whereby by means Carbon dioxide ice particles in the form of ice pellets or scraped Ice from blocks can be produced and transferred from a container to a blasting system working surface are applied, the ice particles produced via an intermediate Grinding device in the form of rollers to a grain size in the range can be shredded from about 0.5 to 1.5 mm and via a downstream conveyor can be fed to a blasting system are according to patent application 101 63 852.3.

Diese bekannte Ausbildung ermöglicht relativ kleine Eispartikel herzustellen, um eine Reinigungswirkung zu erhöhen. Es besteht aber bei anderen Strahleinsätzen die Anforderung, daß die Eispartikelgröße möglicht groß bleibt.This known training allows relatively to produce small ice particles to increase the cleaning effect. It but there is a requirement with other blasting inserts that the ice particle size remains as large as possible.

Die Aufgabe der Erfindung ist es, in Weiterbildung der Hauptanmeldung eine vielseitige Anordnung zu ermöglichen, um unterschiedliche Eispartikelgrößen zu gewährleisten.The object of the invention is in continuing education of the main application to a versatile arrangement enable, to ensure different ice particle sizes.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß im Zuführbereich zur Mahlvorrichtung eine umsteuerbare Klappe zur Führung des zugeführten Materials angeordnet ist und in einer Endstellung der Klappe eine Zuführung zur Walze als Mahlvorrichtung sowie in der anderen Endstellung der Klappe eine Zuführung zu einem gebildeten Durchtritt neben der Walze einstellbar ist.The solution to this problem exists according to the invention in that in feeding a reversible flap for guiding the grinder supplied Material is arranged and in an end position of the flap one feed to the roller as a grinding device and in the other end position Fold a feeder is adjustable to a formed passage next to the roller.

Hierdurch wird in einer Klappeinstellung das Eis zum Walzenspalt geführt. In der anderen Klappenstellung wird das Eis an der Walze vorbeigeführt.This will result in a folding setting the ice led to the nip. In the other flap position, the ice is guided past the roller.

Ferner wird vorgeschlagen, daß der Durchtritt des Behälters direkt mit dem Strahlsystem zur Zuführung verbunden ist.It is also proposed that the passage of the container is directly connected to the blasting system for feeding.

In der Zeichnung ist eine Ausführung der Erfindung schematisch dargestellt. Es zeigen:In the drawing is an execution of the Invention shown schematically. Show it:

1 eine Seitenansicht einer Vorrichtung im Teilschnitt; 1 a side view of a device in partial section;

2 eine gegenüber 1 um 90° gedrehte Ansicht mit einer Klappe in zwei Stellungen. 2 one opposite 1 90 ° rotated view with a flap in two positions.

Bei der dargestellten Anordnung ist ein Behälter mit seinen Behälterwandugnen 12 nach unten konisch eingeschnürt und mit einer entsprechend hergestellten Eis füllung 11 in Form von Eispellets bzw. geschabtem Eis gefüllt. Im unteren Bereich des Behälters ist eine in Pfeilrichtung 14 antreibbare walze 9 angeordnet, die eine gerauhte Oberfläche mit 0,5 bis 3 mm Rauhtiefe aufweisen und zur Zerkleinerung der zugeführten Eispartikel dient. Hierzu ist zwischen Gehäusewand 12 und den walzen 9 ein Spalt gebildet, der entsprechend einstellbar ist, um eine Korngröße im Bereich von etwa 0,5 bis 1,5 mm zu erzielen.In the arrangement shown is a container with its container walls 12 conically constricted at the bottom and filled with an appropriately prepared ice cream 11 filled in the form of ice pellets or scraped ice. At the bottom of the container is one in the direction of the arrow 14 drivable roller 9 arranged, which have a roughened surface with a roughness depth of 0.5 to 3 mm and serves to comminute the supplied ice particles. This is between the housing wall 12 and the reels 9 a gap is formed which can be adjusted accordingly in order to achieve a grain size in the range from approximately 0.5 to 1.5 mm.

Etwa mittig ist im Behälter an der Eiszuführung eine umsteuerbare Klappe 17 angeordnet, die etwa mittig angelenkt ist. Bei einer Klappenstellung A wird das Eis zwischen Gehäusewandung 12 und Walze 9 geführt, so daß es zwangsläufig zerkleinert wird. In Klappenstellung B wird das Eis an der Walze 9 vorbei über einen Durchtritt 18 unzerkleinert einer Förderschnecke 8 zugeführt. Unterhalb der Walze 9 ist in Fallrichtung 16 die Förderschnecke 8 zugeordnet, die das zerkleinerte Material zum nicht näher dargestellten Strahlsystem transportiert.A reversible flap is located in the middle of the container on the ice feed 17 arranged, which is articulated approximately in the middle. With flap position A, the ice is between the housing wall 12 and roller 9 performed so that it is inevitably shredded. In flap position B the ice is on the roller 9 over a passage 18 uncrushed a screw conveyor 8th fed. Below the roller 9 is in the direction of fall 16 the screw conveyor 8th assigned, which transports the shredded material to the blasting system, not shown.

Im Bereich der Förderschnecke 8 ist gegebenenfalls für die Zuführung über den Durchtritt 18 eine Umgehungsöffnung angeordnet, um die granulierten Eispartikel mittels Unterdruck in das Strahlsystem zu saugen, wobei hierfür eine gewisse Trägerluftmenge erforderlich ist.In the area of the screw conveyor 8th is possibly for the feed through the passage 18 a bypass opening is arranged in order to suck the granulated ice particles into the blasting system by means of negative pressure, a certain amount of carrier air being required for this.
