Abstract
Description
Die Erfindung betrifft einen Impeller zum Einspeisen von zu beschleunigendem Strahlmittel in das Schleuderrad einer Strahlanlage, wobei der Impeller im Zentralbereich des Schleuderrades innerhalb einer Zuteilhülse, die eine Zuteilöffnung aufweist, angeordnet ist und in Drehrichtung des Schleuderrades drehbar ist und wobei der Impeller auf die Zuteilhülse zugerichtete, insbesondere tafelförmige, Leitelemente zur Führung des Strahlmittels nach außen aufweist, die an mindestens einer Seitenscheibe angeordnet sind.The invention relates to an impeller for feeding of blasting agent to be accelerated in the blast wheel of a blasting system, wherein the impeller in the central region of the impeller within a metering sleeve having a metering opening, and is rotatable in the direction of rotation of the impeller and wherein the impeller trimmed on the metering sleeve , In particular tabular, guide elements for guiding the blasting agent to the outside, which are arranged on at least one side window.
Mit mit Schleuderrädern ausgerüsteten 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 geschleudert wird. In einem derartigen Schleuderrad bewegen sich nicht sämtliche Partikel des Strahlmittels beim Austritt aus der Zuteilöffnung der Zuteilhülse vorzugsweise tangential und möglichst parallel zu den Schaufeln des rotierenden Schleuderrades 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 blast machines equipped with blast wheels, surfaces of metallic rolled products are freed of scale and / or rust before the surface is given a protective coating by flinging against the surface a blasting medium consisting of fine metal particles. In such a blast wheel, not all of the particles of the blasting medium move outwardly at the exit from the metering opening of the metering sleeve, preferably tangentially and as parallel as possible to the blades of the rotating blast wheel. A considerable number of these particles strike the side windows and the blades and bounce off them, like a ping-pong ball, which not only has a negative effect on the exit speed of the blasting wheel from the blast wheel, but also on an uneven distribution of the blasting medium on the surface to be cleaned. The impact of the abrasive particles on the parts of the impeller also subject to heavy wear.
Ein Impeller mit Zuteilhülse gemäß Oberbegriff des Anspruchs 1 ist in dem Dokument
Aufgabe der Erfindung ist, 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 to reduce the abrasion caused by the blasting agent of the impeller and at the same time to produce a spray pattern with uniform coverage over the entire ejection angle of the blasting agent from the blast wheel at approximately parallel side boundary.
Diese Aufgabe wird ausgehend von einem Impeller zum Einspeisen von Strahlmittel der eingangs beschriebenen Art erfindungsgemäß durch einen Impeller mit Zuteilhülse gemäß Anspruch 1 gelöst.This object is achieved on the basis of an impeller for feeding blasting agent of the type described above according to the invention by an impeller with metering sleeve according to claim 1.
Demnach sind die auf die Zuteilhülse zugerichteten Schenkelenden des Profilstückes in Umfangsrichtung des Impellers, insbesondere in Umfangsrichtung der Seitenscheibe, voneinander beabstandet, wobei zwischen den Schenkeln eine aus Richtung der Zuteilhülse zugängliche Ausnehmung angeordnet ist, insbesondere ein Hohlraum, in die das Strahlmittel eindringen oder ausweichen kann. Die Ausnehmung oder der Hohlraum können dabei unmittelbar durch die Schenkel gebildet sein.Accordingly, the aligned on the Zerteililhülse leg ends of the profile piece in the circumferential direction of the impeller, in particular in the circumferential direction of the side window, spaced from each other, wherein between the legs of an accessible direction of the dispensing sleeve recess is arranged, in particular a cavity into which the blasting agent can penetrate or evade , The recess or the cavity can be formed directly by the legs.
Während die Schenkel des Profil stückes einerseits in Richtung der Zuteilhülse zeigen, zeigen sie zweckmäßigerweise andererseits zumindest annähernd in Richtung der Rotationsachse des Impellers.While the legs of the profile piece on the one hand point in the direction of the metering sleeve, they expediently show on the other hand at least approximately in the direction of the axis of rotation of the impeller.
Was die räumliche Ausrichtung der beiden Schenkel des Profilstückes betrifft, so verlaufen diese vorzugsweise winklig zueinander, insbesondere zumindest annähernd V-förmig bzw. die beiden Schenkel bilden eine V-Form. Vorzugsweise können zumindest ein Schenkel, vorzugsweise beide Schenkel des Profilstückes, winklig zur Radialrichtung des Impellers, insbesondere der Seitenscheibe, verlaufen.As regards the spatial orientation of the two legs of the profile piece, they preferably extend at an angle to each other, in particular at least approximately V-shaped or the two legs form a V-shape. Preferably, at least one leg, preferably both legs of the profile piece, extend at an angle to the radial direction of the impeller, in particular the side window.
Die Schenkel der Profilstücke können in einer weiteren Ausführungsform durch einen vorzugsweise winklig zu den Schenkeln verlaufenden Steg miteinander verbunden sein. Der Steg kann dabei beispielsweise geradlinig oder gekrümmt verlaufen. Es ist weiterhin möglich, die Schenkel der Profilstücke verschieden lang auszubilden. Es hat sich auch bewährt, zwischen den Schenkeln der Profilstücke sich in Richtung auf die Zuteilhülse erstreckende, vorzugsweise tafelförmige Transportelemente vorzusehen.The legs of the profile pieces can be connected to each other in a further embodiment by a preferably extending at an angle to the legs web. The web can run, for example, straight or curved. It is also possible, the legs of the profile pieces of different lengths form. It has also proven useful to provide between the legs of the profile pieces in the direction of the dispensing sleeve extending, preferably tabular transport elements.
Mit der erfindungsgemäßen Ausgestaltung der Leitelemente als Schenkel von Profilstücken wird folgendes erreicht: Zunächst tritt das Strahlmittel über die Entladekanäle mit kanalendseitigen Entladeöffnungen aus dem rotierenden Impeller in die Räume zwischen Zuteilhülse und Impeller auf eine nahezu kreisförmige Bahn ein. Anschließend läuft das Strahlmittel in diesem Bereich zwischen Zuteilhülse und Impeller entlang dieser Kreisbahn um. Durch die Kräfte, die von den insbesondere freien Schenkeln der Profilstücke und gegebenenfalls von den Transportelementen zwischen den Schenkeln der Profilstücke auf das Strahlmittel einwirken, wird dieses schließlich möglichst tangential aus der Zuteilöffnung der Zuteilhülse in den Wirkbereich der Schaufeln des Schleuderrades übergeben. Dadurch ergibt sich ein weicher Übergang des Strahlmittels in den Schaufelbereich des Schleuderrades über die gesamte Breite mit anschließender gleichmäßiger Beschleunigung bis zum Schaufelaustritt. Das Aufprallen des Strahlmittels auf die Schaufeln und Seitenwände des Schleuderrades wird im wesentlichen unterbunden.With the inventive design of the guide elements as legs of profile pieces, the following is achieved: First, the blasting agent passes through the discharge channels with channel end discharge openings from the rotating impeller into the spaces between Zuteilhülse and impeller on a nearly circular path. Subsequently, the blasting medium circulates in this area between the metering sleeve and the impeller along this circular path. By the forces, by the in particular free thighs of the Profile pieces and optionally act on the blasting agent of the transport elements between the legs of the profile pieces, this is finally transferred as tangential as possible from the metering opening of the metering sleeve in the effective range of the blades of the blast wheel. This results in a smooth transition of the blasting agent in the blade area of the blast wheel over the entire width with subsequent uniform acceleration to the blade outlet. The impact of the blasting agent on the blades and side walls of the blast wheel is substantially suppressed.
Der stoßfreie Übergang des Strahlmittels vom als Zentralbeschleuniger wirkenden Impeller in das Schleuderrad bewirkt eine gleichmäßige Führung des Strahlmittels im Schleuderrad, wodurch nicht nur eine gleichmäßige Verteilung des Strahlmittels auf der zu behandelnden Oberfläche erzielt wird, sondern auch der Verschleiß am Schleuderrad sowie die zur Beschleunigung des Strahlmittels aufzuwendende Energie verringert werden.The bumpless transition of the blasting medium acting as a central accelerator impeller in the impeller causes a uniform guidance of the blasting agent in the impeller, whereby not only a uniform distribution of the blasting agent is achieved on the surface to be treated, but also the wear on the impeller and the acceleration of the blasting medium energy to be reduced.

Die Profilstücke 3 weisen jeweils zwei als Strahlmittel-Leitelemente dienende Schenkel 5 und 6 auf, die an ihren zumindest annähernd zum Impellerzentrum bzw. zur Impeller-Rotationsachse gerichteten Enden miteinander verbunden sind. Die Schenkel 5 und 6 zeigen mit ihren freien Enden auf die Zuteilhülse 1, wobei jeweils zwischen den Schenkeln 5 und 6 aus Richtung der Zuteilhülse zugängliche Hohlräume ausgebildet sind. Die Profilstücke 3 sind dabei derart in Umfangsrichtung über den umlaufenden Randbereich der Stirnseite der Seitenscheibe 4 verteilt, dass zwischen benachbarten Schenkeln benachbarter Profilstücke 3 Kanäle 7 gebildet sind.The individual profile pieces are distributed in the circumferential direction over the circumferential edge region of the end face of the side window 4. In this case, each profile piece 3 is spaced from the respective adjacent profile piece 3 in the circumferential direction. The profile pieces 3 each have two serving as blasting agent
Was die Schenkel 5 und 6 eines Profilstückes 3 betrifft, so können diese, wie in einem Sektor A des Impellers 2 gezeigt ist, eine V-Form beschreiben. In einer anderen Ausführungsform können die Schenkel 5 und 6 auch über einen Steg 9 miteinander verbunden sein, vgl. Sektor B, sodass das Profilstück 3 insgesamt annähernd als U-Form ausgebildet ist.
