Schleuderrad Centrifugal wheel
Beschreibungdescription
Die Erfindung bet'rifft. ein Schleuderrad für eine Strahlanlage , das um seine Längsachse drehbar , mot'orisch ant'reibbar und als Schauf elrad ausgebildet' ist sowie in seinem Zent'ralbereich eine Zut eil- hülse mit' einer Zut'eilöf f nung aufweist. , wobei in der Zut'ei lhülse zusammen mit! dem Schleuderrad ein Hilfsschleuderrad rotiert?, in den das zu beschleunigende St'rahlmitt'el in Axialricht'ung eingespeist, wird.The invention relates. a blower for a blasting machine, the formed Elrad rotatable about its longitudinal axis, and as mot'orisch ant'reibbar Schauf 'is as well as in its Zent'ralbereich a Zut express sleeve with' a Zut 'f eilöf voltage has. , in the ingredient sleeve together with! the centrifugal wheel an auxiliary centrifugal wheel rotates, into which the steel to be accelerated is fed in the axial direction.
Mit' derartigen, z.B. aus der DE-OS 25 38 228 bekannten Schleuderrädern ausgerüstete Anlagen werden Oberflächen von metallischen Walzproduktren vom Zunder und/oder Rost? befreit?, bevor die Oberfläche einen Schutzanstrich erhält, indem gegen die Oberfläche ein aus feinen Met'allpartikeln bestehendes St'rahlmitt'el geschleudert" wird. In einem derartigen Schleuderrad bewegen sich nicht: sämt'liche Partikel des Strahlmittels beim Aust'rit't' aus dem Impeller radial und möglichst, parallel zu den Schaufeln nach außen. Eine beträchtliche Anzahl dieser Partikel schlägt? an den Seit'enscheiben und den Schaufeln an und prallt: davon vergleichbar einem Ping-Pong- Ball zurück, was sich nicht' nur negativ auf die Aust'ritt'sgeschwindigkeit? des St'rahlmit't'els aus dem Schleuderrad auswirkt?, sondern auch zu einer ungleichmäßigen Vert?eilung des St'rahlmit't'els auf der zu reinigenden Oberfläche führt?. Durch das Aufprallen der Strahlrait't'elpart'ikel an den Teilen des Schleuderrades unt'erliegt? dasselbe außerdem einem st?arken Verschleiß.With such systems equipped, for example, from DE-OS 25 38 228 known centrifugal wheels, surfaces of metallic rolled products from scale and / or rust? before the surface is given a protective coating by throwing a steel material consisting of fine metal particles " against the surface. In such a centrifugal wheel there is no movement: all particles of the blasting medium when it is removed "From the impeller radially and as far as possible, parallel to the blades to the outside. A considerable number of these particles hit? on the side windows and the blades and rebound: comparable to a ping-pong ball, which is not 'only negative t'els affects the Aust'ritt'sgeschwindigkeit? St'rahlmit of 'from the blower ?, but also to uneven Vert? eilung of St'rahlmit't'els on the surface to be cleaned leads ?. By Impact of the jet rit ' t'elpart ' icle on the parts of the centrifugal wheel? the same also a heavy wear.
Aufgabe der Erfindung ist? es nun, den durch das St'rahlmitt'el bedingten Verschleiß des Schleuderrades zu verringern und zugleich ein St'rahlbild mit? gleichmäßiger Elndeckung über den gesamt'en Auswurfwinkel des St'rahlmit'tels aus dem Schleuderrad bei annähernd paralleler Seit'enbegrenzung zu erzeugen.The object of the invention is? it is now to reduce the wear of the centrifugal wheel caused by the steel and, at the same time, a steel picture with? to produce uniform Elndeckung gesamt'en over the ejection angle of the St 'rahlmit'tels from the centrifugal wheel in approximately parallel Seit'enbegrenzung.
Diese Aufgabe wird erfindungsgemäß ausgehend von einem Schleuderrad der eingangs beschriebenen Gat't'ung dadurch gelöst, daß die Einspeiseöffnung für das St'rahlmitt'el in das Hilfsschleuderrad, in dessen Zentrum ein Rotationskörper vorgesehen ist', seitlich vom Rotationskörper in Drehricht'ung des Schleuderrades unmittelbar hinter der Zut'eil- öffnung mündet? und daß die Länge des Rot'at'ionskör- pers mindestens der Breite des Hilfsschleuderrades entspricht?. Dabei kann das Hilfsschleuderrad unab- hängig vom Schleuderrad sowie mit? variabler Drehzahl angetrieben werden und der Rot'at'ionskörper beliebig z.B. als Zylinder, Kegel oder dgl. gestaltet? sein.This object is achieved, starting from a centrifugal wheel of the Gat't'ung described in the introduction, that the feed opening for the steel means in the auxiliary centrifugal wheel, in the center of which a rotary body is provided, laterally from the rotary body in the direction of rotation of the Centrifugal wheel opens directly behind the component opening? and that the length of the rotary body corresponds at least to the width of the auxiliary centrifugal wheel ?. The auxiliary centrifugal wheel can depending on the centrifugal wheel and with? variable speed are driven and the Rot'at'ionskörper designed as a cylinder, cone or the like? his.
Durch die erfindungsgemäße Anordnung der Einspeiseöffnung für das St'rahlmitt'el und die Ausgestaltung des Hilfsschleuderrades wird erreicht:, daß sämt?- liche eingespeist?en Partikel des Strahlmit'tels auf einer spiralförmigen Umlaufbahn aus dem Hilfsschleuderrad in das Schleuderrad eintreten, da sie nicht unmittelbar, sondern nur auf einer Ro- t'at'ionsbahn von der Einspeiseöffnung zur Zut'eilöff- nung gelangen können. Dadurch ergibt' sich eine weiche Übernahme des St'rahlmit't'els in den Schaufelbereich mit anschließender gleichmäßiger Beschleunigung bis zum Schaufelaust'rit?t' und wird das Aufprallen des St'rahlmit't'els auf die Schaufeln und Seit'enwände des Schleuderrades im wesentlichen unterbunden. Der st'oßfreie Übergang des St?rahlmit'- t'els vom als Zent'ralbeschleuniger wirkenden Hilfsschleuderrad in das Schleuderrad gewährleist'et' eine gleichmäßige Führung des St?rahlmit't'els im Schleuderrad, wodurch nicht? nur eine gleichmäßige Vert?eilung des St'rahlmit't?els auf der zu behandelnden Oberfläche erzielt?, sondern auch der Verschleiß am Schleuderrad sowie die zur Beschleunigung des St'rahlmit't'els aufzuwendende Energie verringert: werden.The arrangement according to the invention of the feed opening for the steel medium and the design of the auxiliary centrifugal wheel ensure that all the particles of the blasting medium which are fed in enter the centrifugal wheel in a spiral orbit from the auxiliary centrifugal wheel, since they do not directly, but only on a rot'at'ion path from the feed opening to the component opening. This results in a soft transfer of the St'rahlmit't'els into the bucket area with subsequent even acceleration until the bucket is ' rit? T 'and the impact of the St'rahlmit't ' els on the blades and side walls of the Centrifugal wheel essentially prevented. The smooth transition of the steel medium from the auxiliary centrifugal wheel acting as a central accelerator into the centrifugal wheel ensures a uniform guidance of the steel ram in the centrifugal wheel, so that? only an even distribution of the steel rod on the surface to be treated is achieved, but also the wear on the centrifugal wheel and the energy required to accelerate the steel rod are reduced: are reduced.
Bei einer bevorzugt'en Weiterbildung der Erfindung sind im Hilfsschleuderrad Rippen oder Hilfsschaufeln angeordnet', die sich in Richt'ung auf dessen Einspeiseseit'e verjüngen können, so daß sie beim Rotieren des Schleuderrades im Hilfsschleuderrad einen in Fließrichtung des Strahlmit'tels sich verengenden Hohlraum bilden, über den das St'rahlmitt'el zur Erhöhung des Durchsatzes optimal in den Wirkungsbereich des Hilfsschleuderrades eindringen kann.In a development of the invention bevorzugt'en ribs or auxiliary blades are arranged in Hilfsschleuderrad ', which may be tapered in Richt'ung on its Einspeiseseit'e, so that it has a direction of flow of the Strahlmit during rotation of the centrifugal wheel in Hilfsschleuderrad' means of narrowing cavity form, through which the steel medium can optimally penetrate into the effective area of the auxiliary centrifugal wheel to increase the throughput.
