An impeller (9) comprising discharge openings (11) rotates in the distributing bushing (7) together with the centrifugal wheel (1), wherein the shots which are to be accelerated enter in an axial direction, the feed pipe (3) for the shots discharges into the impeller (9) and is provided with a ring-shaped tongue (10) which protrudes into the impeller (9) in the region of the distributing opening (8).

Description

Die Erfindung betrifft eine Einrichtung zum Einspeisen von Strahlmittel über eine Zuleitung in den Zentralbereich des Schleuderrades einer Strahlanlage, wobei im Zentralbereich eine Zuteilhülse mit einer Zuteilöffnung vorgesehen ist und in der Zuteilhülse zusammen mit dem Schleuderrad ein Impeller mit Entladeöffnungen rotiert, in den das zu beschleunigende Strahlmittel in Axialrichtung eintritt.The invention relates to a device for feeding blasting agent via a supply line into the central region of the blast wheel of a blasting system, wherein in the central region an allotment sleeve is provided with a metering opening and in the metering sleeve together with the impeller rotates an impeller with discharge openings, in which the blasting agent to be accelerated enters in the axial direction.

Mit z. B. aus der DE-OS 25 38 228 bekannten Schleuderrädern ausgerüstete Anlagen 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 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 z. B. from DE-OS 25 38 228 known spinning wheels equipment equipped surfaces of metallic rolled products of the scale and / or rust are freed before the surface receives a protective coating by a flinging of fine metal particles blasting agent is thrown against the surface. In such a blast wheel, not all of the particles of the blasting medium move radially outward and as far as possible parallel to the blades when they exit the impeller. A considerable number of these particles strike the side windows and the blades and bounces back comparable to a ping-pong ball, which not only has a negative effect on the exit velocity of the blasting agent from the impeller, but also leads to an uneven distribution of the blasting agent on the surface to be cleaned. The impact of the abrasive particles on the parts of the impeller also subject to heavy wear.

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 therefore 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 medium from the blast wheel with approximately parallel side boundary.

Diese Aufgabe wird erfindungsgemäß ausgehend von einer Einrichtung zum Einspeisen von Strahlmittel der eingangs beschriebenen Gattung dadurch gelöst, daß die Zuleitung für das Strahlmittel in den Impeller mündet und eine rinnenförmige Zunge aufweist, die im Bereich der Zuteilöffnung in den Impeller hineinragt. Dabei kann der Impeller unabhängig vom Schleuderrad und mit variabler Drehzahl angetrieben werden. Es ist außerdem möglich, im Zentrum des Impellers ein mit der Antriebswelle des Schleuderrades in Wirkverbindung stehendenes Rührelement vorzusehen.This object is achieved on the basis of a device for feeding blasting agent of the type described above in that the feed line for the blasting agent opens into the impeller and has a channel-shaped tongue which protrudes in the region of the metering opening in the impeller. It can the Impeller independent of the impeller and driven at variable speed. It is also possible to provide in the center of the impeller an operative with the drive shaft of the impeller stirring member.

Durch die erfindungsgemäße Ausgestaltung der Mündung der Zuleitung mit einer in den Impeller ragenden rinnenförmigen Zunge, die den Bereich der Zuteilöffnung für das Strahlmittel in das Schleuderrad im wesentlichen abdeckt, wird erreicht, daß sämtliche eingespeisten Partikel des Strahlmittels auf einer spiralförmigen Umlaufbahn aus dem Impeller in das Schleuderrad eintreten. Die in den Impeller ragende Zunge ist für das aus der Zuleitung austretende Strahlmitel eine Barriere auf dem direkten Weg zur Zuteilöffnung, so daß dasselbe nicht unmittelbar, sondern nur auf einer Rotationsbahn von der Zuleitung zur Zuteilöffnung gelangen kann. Dadurch ergibt sich ein weicher Übergang des Strahlmittels in den Schaufelbereich des Schleuderrades 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 Impeller 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 inventive design of the mouth of the feed line with a projecting into the impeller trough-shaped tongue that covers the area of the metering opening for the blasting agent in the blast wheel substantially, it is achieved that all injected particles of the abrasive on a spiral orbit from the impeller into the Enter blower wheel. The protruding into the impeller tongue is for the emerging from the supply line Blaze a barrier on the direct path to the metering opening, so that it can not go directly from the supply line to the metering opening, but only on a rotational path. This results in a smooth transition of the blasting agent in the blade area of the impeller with subsequent uniform acceleration to the blade outlet and is the impact of the blasting agent essentially prevented on the blades and side walls of the blast wheel. The bumpless transition of the blasting agent acting as a central accelerator impeller in the impeller ensures uniform guidance of the blasting agent in the impeller, which not only achieves a uniform distribution of the blasting agent on the surface to be treated, but also the wear on the impeller and expended on the acceleration of the blasting agent Energy can be reduced.
