Description

Die Erfindung betrifft eine Einrichtung zum Einspeisen von Strahlmittel über ein Zulaufrohr in den Zentralbereich des als Schaufelrad ausgebildeten, um seine Längsachse drehbaren und motorisch antreibbaren Schleuderrades einer Strahlanlage, wobei im Zentralbereich eine Zuteilhülse mit einer Zuteilöffnung vorgesehen ist und in der Zuteilhülse zusammen mit dem Schleuderrad ein Hilfsschleuderrad, in dessen Zentrum ein Rotationskörper vorgesehen ist, rotiert und in welches das zu beschleunigende Strahlmittel in Axialrichtung eintritt, wobei die Länge des Rotationskörpers mindestens der Breite des Hilfsschleuderrades entspricht.The invention relates to a device for feeding of blasting media via an inlet pipe into the central area the trained as a paddle wheel to his Longitudinal axis of rotating and motor-driven centrifugal wheel a blasting machine, being in the central area an allotment sleeve with an allotment opening is provided and in the allotment sleeve together with the centrifugal wheel an auxiliary centrifugal wheel with a rotating body in the center is provided, rotates and into which the abrasive to be accelerated in the axial direction occurs, the length of the rotating body at least corresponds to the width of the auxiliary centrifugal wheel.

Mit derartigen, z. B. aus der DE-OS 25 38 228 bekannten Strahlanlagen werden Oberflächen von metallischen Walzprodukten vom Zunder und/oder Rost befreit, bevor die Oberfläche einen Schutzanstrich erhält, indem gegen die Oberfläche ein aus feinen Metallpartikeln bestehendes Strahlmittel von dem Schleuderrad der Anlage geschleudert wird. In einem derartigen Schleuderrad bewegen sich nicht sämtliche Partikel des Strahlmittels beim Austritt aus dem Impeller radial und möglichst parallel zu den Schaufeln nach außen. Eine beträchtliche Anzahl dieser Partikel schlägt an den Seitenscheiben und den Schaufeln an und prallt davon vergleichbar einem Ping-Pong-Ball zurück, was sich nicht nur negativ auf die Austrittsgeschwindigkeit des Strahlmittels aus dem Schleuderrad auswirkt, sondern auch zu einer ungleichmäßigen Verteilung des Strahlmittels auf der zu reinigenden Oberfläche führt. Durch das Aufprallen der Strahlmittelpartikel an den Teilen des Schleuderrades unterliegt dasselbe außerdem einem starken Verschleiß.With such, e.g. B. from DE-OS 25 38 228 known Blasting machines become surfaces of metallic Rolled products free of scale and / or rust before the surface receives a protective coating by against the surface of fine metal particles existing blasting media from the centrifugal wheel Plant is thrown. In such a centrifugal wheel not all particles of the Radial abrasive upon exit from the impeller and as parallel to the blades as possible to the outside. A significant number of these particles hit on the side windows and the blades and bounces comparable to a ping pong ball back what not only negatively affect the exit speed of the abrasive from the centrifugal wheel, but also to an uneven distribution of the Abrasive leads on the surface to be cleaned. By the impact of the abrasive particles on the Parts of the centrifugal wheel are also subject to the same heavy wear.

Im nächstkommenden Stand der Technik, der GB-A-1 552 679 wird eine tragbare Strahleinrichtung beschrieben, in welche das Strahlmittel mit einem unter Überdruck stehenden Luft- oder Gasstrom über ein Zulaufrohr in einen Impellerkäfig eingespeist wird. Im Impellerkäfig ist eine Zuteilöffnung ausgebildet, über welche das Strahlmittel aus dem Impellerkäfig in den Wirkbereich der Schaufeln eines Schleuderrades eintritt. Die Mündung des Zulaufrohres ist in axialer Richtung auf die Zuteilöffnung gerichtet, so daß von dem mit Druckluft eingeblasenen Strahlmittel ein erheblicher Teil unmittelbar in die Zuteilöffnung eintritt, d. h. vor dem Eintritt in die Zuteilöffnung auf keiner Kreisbahn, sondern linear und quer zur Schaufelbewegung transportiert wird.In the closest prior art, GB-A-1 552 679 becomes a portable beam device described in which the abrasive with a air or gas flow under pressure an inlet pipe fed into an impeller cage becomes. An allotment opening is formed in the impeller cage, through which the abrasive from the impeller cage in the effective area of the blades of a centrifugal wheel entry. The mouth of the inlet pipe is axial Direction directed to the feed opening, so that from the blasting agent blown with compressed air is a considerable one Part immediately enters the feed opening, d. H. before entering the allotment opening on none Circular path, but linear and transverse to the blade movement is transported.

Aus der GB 441 466 A ist weiter eine Strahleinrichtung bekannt, bei der das Strahlmittel unter der Einwirkung der Schwerkraft über ein Zulaufrohr in einen Impeller eingespeist wird. Die Austrittsöffnung des Zulaufrohres mündet in den Impeller und erstreckt sich über dessen gesamte Breite oder Tiefe. Der Impeller ist von einer Zuteilhülse umgeben. In der Zuteilhülse ist eine Zuteilöffnung vorgesehen, über welche das Strahlmittel aus dem Impeller an ein Schleuderrad abgegeben wird. Die Zuteilhülse ist verstellbar um die Achse des Schleuderrades gehalten, um durch Verstellen der Lage der Zuteilöffnung die Richtung des von der Strahleinrichtung abgegebenen bzw. aus dem Schleuderrad austretenden beschleunigten Strahlmittels den jeweiligen Bedürfnissen anzupassen. Aufgrund der Einspeisung des Strahlmittels in den Impeller unter Schwerkraft bleibt die Lage der Austrittsöffnung des Zulaufrohres im Impeller unabhängig von der Stellung der Zuteilöffnung in der Zuteilhülse unverändert. Dies wirkt sich nicht nur negativ auf die Austrittsgeschwindigkeit des Strahlmittels aus dem Schleuderrad aus, sondern bedingt auch eine ungleichmäßige Verteilung des Strahlmittels auf der zu reinigenden Oberfläche.From GB 441 466 A there is also a beam device known in which the abrasive under the action gravity through an inlet pipe into an impeller is fed. The outlet opening of the inlet pipe flows into the impeller and extends over it entire width or depth. The impeller is one Allotment sleeve surrounded. There is an allotment opening in the allotment sleeve provided, via which the abrasive is delivered from the impeller to a centrifugal wheel. The allocation sleeve is adjustable around the axis of the Centrifugal wheel held to by adjusting the position the dispensing opening the direction of the of the beam device emitted or emerging from the centrifugal wheel accelerated abrasive the respective Adapt to needs. Because of the feed of the abrasive in the impeller under gravity the position of the outlet opening of the inlet pipe remains in the impeller regardless of the position of the feed opening unchanged in the allocation sleeve. This affects not just negative on the exit speed the abrasive from the centrifugal wheel, but also causes an uneven distribution of the abrasive on the surface to be cleaned.

Aufgabe der Erfindung ist es nun, den durch das Strahlmittel bedingten Verschleiß des Schleuderrades zu verringern und zugleich ein Strahlbild mit gleichmäßiger Eindeckung über den gesamten Auswurfwinkel des Strahlmittels aus dem Schleuderrad bei annähernd paralleler Seitenbegrenzung zu erzeugen.The object of the invention is now that of the abrasive conditional wear of the centrifugal wheel reduce and at the same time a spray pattern with more uniform Coverage over the entire ejection angle of the Blasting media from the centrifugal wheel at approximately parallel Generate page boundary.

Diese Aufgabe wird erfindungsgemäß ausgehend von einer Einrichtung der eingangs beschriebenen Gattung zum Einspeisen von Strahlmittel in das Schleuderrad einer Strahlanlage dadurch gelöst, daß die Einspeiseöffnung des Zulaufrohres für das Strahlmittel in das Hiifsschleuderrad seitlich vom Rotationskörper in Drehrichtung des Schleuderrades vorzügsweise unmittelbar hinter der Zuteilöffnung mündet. Dabei kann das Hilfsschleuderrad unabhängig vom Schleuderrad sowie mit variabler Drehzahl angetrieben werden und der Rotationskörper beliebig z.B. als Zylinder, Kegel oder dgl. gestaltet sein.This object is achieved on the basis of a Establishment of the genus described above for Feeding abrasive into the centrifugal wheel Blasting system solved in that the feed opening of the feed pipe for the blasting medium in the blast wheel to the side of the rotating body in the direction of rotation the centrifugal wheel preferably directly behind the feed opening empties. The auxiliary centrifugal wheel can do this independently from the centrifugal wheel and with variable speed be driven and the rotating body any e.g. designed as a cylinder, cone or the like his.

Durch die erfindungsgemäße Anordnung der Einspeiseöffnung für das Strahlmittel und die Ausgestaltung des Hilfsschleuderrades wird erreicht, daß sämtliche eingespeisten Partikel des Strahlmittels auf einer spiralförmigen Umlaufbahn aus dem Hilfsschleuderrad in das Schleuderrad eintreten, da sie nicht unmittelbar, sondern nur auf einer Rotationsbahn von der Einspeiseöffnung zur Zuteilöffnung gelangen können. Dadurch ergibt sich eine weiche Übernahme des Strahlmittels in den Schaufelbereich mit anschließender gleichmäßiger Beschleunigung bis zum Schaufelaustritt und wird das Aufprallen des Strahlmittels auf die Schaufeln und Seitenwände des Schleuderrades im wesentlichen unterbunden. Der stoßfreie Übergang des Strahlmittels vom als Zentralbeschleuniger wirkenden Hilfsschleuderrad in das Schleuderrad gewährleistet eine gleichmäßige Führung des Strahlmittels im Schleuderrad, wodurch nicht nur eine gleichmäßige Verteilung des Strahlmittels auf der zu behandelnden Oberfläche erzielt, sondern auch der Verschleiß am Schleuderrad sowie die zur Beschleunigung des Strahlmittels aufzuwendende Energie verringert werden.Due to the arrangement of the feed opening according to the invention for the abrasive and the design the auxiliary centrifugal wheel ensures that all fed particles of the abrasive on a spiral orbit from the auxiliary centrifugal wheel enter the centrifugal wheel because not immediately, but only on a rotation path from the feed opening to the feed opening can reach. This results in a soft takeover of the abrasive in the blade area with subsequent even acceleration until the blade exit and the impact will of the abrasive on the blades and Sidewalls of the centrifugal wheel essentially prevented. The smooth transition of the abrasive from the auxiliary centrifugal wheel acting as a central accelerator guaranteed in the blast wheel uniform guidance of the blasting medium in the Centrifugal wheel, which not only ensures a uniform Distribution of the abrasive on the one to be treated Surface achieved, but also wear on the centrifugal wheel and the one to accelerate the Reduced energy to be used become.

Bei einer bevorzugten Weiterbildung der Erfindung sind im Hilfsschleuderrad Rippen oder Hilfsschaufeln angeordnet, die sich in Richtung auf dessen Einspeiseseite verjüngen können, so daß sie beim Rotieren des Schleuderrades im Hilfsschleuderrad einen in Fließrichtung des Strahlmittels sich verengenden Hohlraum bilden, über den das Strahlmittel zur Erhöhung des Durchsatzes optimal in den Wirkungsbereich des Hilfsschleuderrades eindringen kann.In a preferred development of the invention there are ribs or auxiliary blades in the auxiliary centrifugal wheel arranged, which is towards its Feed side can taper, so that when Rotate the centrifugal wheel in the auxiliary centrifugal wheel one in the direction of flow of the abrasive form narrowing cavity over which the blasting agent to increase the throughput optimally in penetrate the effective area of the auxiliary centrifugal wheel can.
