Abstract

Bei einer Trennstrahlanlage, die eine größere Anzahl von Luftauslassdüsen umfasst, sind diese einander unmittelbar benachbart in einem Strang angeordnet. Die Düsen haben jeweils einen quaderförmigen Düsenkörper (17), der entlang seiner parallel zu seinen vier Längskanten (18/1 bis 18/4) verlaufenden zentralen Längsachse (26) von einem Düsenkanal (24) durchsetzt ist, der eintrittsseitig einen sich stetig zur Austrittsseite hin verjüngenden Beschleunigungsabschnitt und einen an diesen glatt anschließenden, zylindrisch rohrförmigen Auslassabschnitt konstanten Durchmessers d hat, wobei der Durchmesser des Beschleunigungsabschnitts zwischen dem Durchmesser D, der an der einen Stirnseite des Quaders angeordneten Eintrittsöffnung als Maximalwert und dem Minimalwert d variiert, der gleich dem Durchmesser des rohrförmigen Auslassabschnitts ist. Der Abstand a der beidseits der die zentrale Längsachse (26) des Düsenkanals (24) enthaltenden Mittelebene (36) des Düsenblocks (17) verlaufenden breiten Längsflächen (28/1 und 28/2) des Düsenblocks, mit denen dieser in der Stranganordnung der Düsen an den jeweils benachbarten Düsen anliegt, ist signifikant kleiner als der lichte Durchmesser D der Eintrittsöffnung (22) des Beschleunigungsabschnitts (29) und signifikant größer ist als der lichte Durchmesser d des zylindrischen Austrittsabschnitts (31) des Düsenkanals (24) und in bevorzugter spezieller Gestaltung des Düsenblocks ungefähr gleich der Hälfte der Summe der Durchmesser D und d der eintrittsseitig und der austrittsseitigen Düsenkanal-Öffnung.

In a separation blasting system comprising a larger number of air outlet nozzles, these are arranged immediately adjacent to each other in a strand. The nozzles each have a cuboid nozzle body (17), which is traversed along its parallel to its four longitudinal edges (18/1 to 18/4) extending central longitudinal axis (26) of a nozzle channel (24), the inlet side a steadily to the outlet side has a tapering acceleration section and a smoothly adjoining this, cylindrical tubular outlet portion of constant diameter d, wherein the diameter of the acceleration section between the diameter D, arranged at the one end face of the cuboid inlet opening as maximum value and the minimum value d, which is equal to the diameter of tubular outlet section is. The distance a of both sides of the central longitudinal axis (26) of the nozzle channel (24) containing center plane (36) of the nozzle block (17) extending wide longitudinal surfaces (28/1 and 28/2) of the nozzle block, with which this in the strand arrangement of the nozzle is applied to the respectively adjacent nozzles, is significantly smaller than the clear diameter D of the inlet opening (22) of the acceleration section (29) and significantly larger than the clear diameter d of the cylindrical outlet portion (31) of the nozzle channel (24) and in a preferred special design of the nozzle block is approximately equal to half the sum of the diameters D and d of the inlet side and the outlet side nozzle channel opening.
