Abstract

1. A fan blower for blasting medium installations, having a guide disc wheel and casting scoops (1) which are attached to the guide disc wheel by means of clamping elements as locking means and whose front and rear sides are constructed identically, symmetrically in relation to their longitudinal axis (B-B) and to a transverse axis (A-A) which extends perpendicularly to the longitudinal axis in the scoop plane and in which recesses (4) are formed for receiving the clamping elements, characterised in that each casting scoop (1) has in cross-section the shape of a horizontal Z.

Description

Die Erfindung bezieht sich auf ein Schleuderrad für Strahlmittelanlagen mit einem Leitscheibenrad und mit an dem Leitscheibenrad mit Hilfe von Spannelementen als Arretierungen befestigten Wurfschaufeln, deren Vor- und Rückseite gleich, symmetrisch zu ihrer Längsachse und zu einer senkrecht zur Längsachse in der Schaufelebene verlaufenden Querachse ausgebildet ist, in der Ausnehmungen für die Aufnahme der Spannelemente angeordnet sind.The invention relates to a centrifugal wheel for abrasive systems with a guide disk wheel and with throwing vanes fastened to the guide disk wheel with the aid of tensioning elements as detents, the front and back of which are identical, symmetrical to their longitudinal axis and to a transverse axis running perpendicular to the longitudinal axis in the blade plane , are arranged in the recesses for receiving the clamping elements.

Bei dem in der EU-OS 79 100 943 beschriebenen Schleuderrad ist jede Wurfschaufel spiegelsymmetrisch zu zwei aufeinander senkrechten Achsen ausgebildet. Da jede Wurfschaufel in einer dieser Achsen, nämlich in der Querachse, auch Ausnehmungen für die Aufnahme der Arretierung an dem Leitscheibenrad aufweist, ist ein vierfacher Einsatz der Wurfschaufeln möglich: Jede Wurfschaufel kann um 1800 sowohl um ihre Längsachse als auch um ihre Querachse gedreht und in jeder dieser Lagen in das Leitscheibenrad eingesetzt werden. Das Schleuderrad kann in beiden Drehrichtungen bewegt werden. Das Leitscheibenrad erlaubt durch die Symmetrie über die Querachse eine Verdrehung des Radkörpers mit den Schaufeln um 180° mit der Möglichkeit für Rechts- und Linksumlauf. Der gleiche Effekt wird durch Umsetzen der Spannelemente für die Arretierung jeweils auf die der Drehrichtung abgewendete Seite der Wurfschaufeln für zwei Drehrichtungen des Schleuderrads erzielt. So ausgestaltete Wurfschaufeln sind optimal nutzbar. Mit ihnen lassen sich die maximal möglichen Standzeiten erzielen.In the centrifugal wheel described in EU-OS 79 100 943, each throwing blade is mirror-symmetrical to two mutually perpendicular axes. Since each throwing blade in one of these axes, namely in the transverse axis, also has recesses for receiving the locking device on the guide disc wheel, the throwing blades can be used four times: each throwing blade can be rotated by 180 ° both about its longitudinal axis and about its transverse axis and can be inserted in the guide disc wheel in each of these positions. The centrifugal wheel can be moved in both directions. Due to the symmetry about the transverse axis, the guide pulley wheel allows the wheel body with the blades to be rotated by 180 ° with the possibility of right and left rotation. The same effect is achieved by implementing the clamping elements for the locking achieved on the side of the throwing blades facing away from the direction of rotation for two directions of rotation of the centrifugal wheel. Throwing blades designed in this way can be optimally used. The maximum possible downtimes can be achieved with them.

Die Spiegelsymmetrie jeder Wurfschaufel bezogen auf die Längs- und Querachse, die im Querschnitt für die Wurfschaufel die Form eines Doppel-T ergibt, führt dazu, daß mit ihr im Betrieb ein bestimmter Strahlbereich überstrichen wird. Dieser Strahlbereich bleibt konstant, gleichgültig in welcher der vier möglichen Lagen die Wurfschaufel in das Leitscheibenrad eingesetzt wird. Dies ist der Vorteil des vorgenannten Schleuderrads. Es gibt jedoch auch Einsatzfälle, bei denen es erwünscht ist, wenn der Strahlbereich desselben Schleuderrads in Grenzen verändert, insbesondere verbreitert werden kann. Aus der DE-AS 14 77 979 ist es bekannt, zu diesem Zweck den Winkel, den die Wurfschaufel mit der Tangente an das Leitscheibenrad bildet, stumpf oder spitz zu wählen, also die Wurfschaufel bezogen auf die Drehrichtung des Leitscheibenrads vorwärts oder rückwärts geneigt einzusetzen. Das setzt zwei verschiedene Wurfschaufeln oder aufwendige Befestigungsvorrichtungen voraus.The mirror symmetry of each throwing blade in relation to the longitudinal and transverse axes, which results in the shape of a double T in cross section for the throwing blade, means that it is used to sweep a certain beam area during operation. This jet area remains constant, irrespective of the four possible positions in which the throwing vane is inserted into the guide disc wheel. This is the advantage of the above-mentioned centrifugal wheel. However, there are also cases in which it is desirable if the jet area of the same centrifugal wheel can be changed within limits, in particular if it can be broadened. From DE-AS 14 77 979 it is known for this purpose to choose the angle which the throwing vane forms with the tangent to the guide disc wheel, obtuse or pointed, that is, to use the throwing vane inclined forwards or backwards in relation to the direction of rotation of the guide disc wheel. This requires two different throwing blades or complex fastening devices.

Der Erfindung liegt die Aufgabe zugrunde, das in der EV-OS 79 100 943 beschriebene Schleuderrad so weiterzubilden, daß mit ihm unterschiedliche Strahlbereiche überstrichen werden können, jedoch unter Beibehaltung eines für alle Wurfschaufeln gleichen symmetrischen Aufbaus, der den Einbau in vier verschiedenen Lagen bei unveränderter Befestigung im Leitscheibenrad ermöglicht. Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß jede Wurfschaufel durch Drehung jedes Schaufelpunktes um 180° um die Längsachse und/oder durch Spiegelung an der Querachse gebildet ist.The invention has for its object to develop the centrifugal wheel described in EV-OS 79 100 943 so that different beam areas can be swept with it, but while maintaining a symmetrical structure for all throwing blades, the installation in four different positions with unchanged Fastening in the guide pulley enables. This object is achieved according to the invention in that each throwing blade is formed by rotating each blade point by 180 ° about the longitudinal axis and / or by mirroring on the transverse axis.

Beim Schleuderrad nach der EU-OS 79 100 943 sind die Symmetrieachsen solche zur Erzielung einer Spiegelsymmetrie: Jede Wurfschaufel ist spiegelsymmetrisch zur Längsachse ausgebildet. Bei der Erfindung ist die Längsachse Symmetrieachse für eine Drehung. Die rechte oder linke Hälfte der Wurfschaufel entsteht dadurch, daß die jeweils andere Hälfte um die Längsachse um 180° gedreht wird; und zwar unter Beibehaltung der beschriebenen Bedingung, daß die obere oder untere Hälfte der Wurfschaufel an der Querachse gespiegelt wird. Es entsteht so eine Wurfschaufel, deren Grundplatte bezogen auf die Drehrichtung des Leitscheibenrads nicht vorwärts oder rückwärts geneigt, sondern seitlich schräg geneigt ist. Der Winkel, unter dem die Wurfschaufel bezogen auf die Tangente an das Leitscheibenrad angeordnet ist, beträgt 90°. Die Ebene, die die Schaufelebene mit der Drehrichtung des Leitscheibenrades bildet, verläuft nicht mehr unter 90°, sondern unter einem von 90° abweichenden Winkel. Dies ergibt, wenn aufeinanderfolgende gleich aufgebaute Wurfschaufeln unter Supplementwinkeln eingebaut werden, den vergrößerten Strahlbereich.In the centrifugal wheel according to EU-OS 79 100 943, the axes of symmetry are those to achieve mirror symmetry: each throwing blade is mirror-symmetrical to the longitudinal axis. In the invention, the longitudinal axis is an axis of symmetry for a rotation. The right or left half of the throwing blade is created by rotating the other half around the longitudinal axis by 180 °; while maintaining the described condition that the upper or lower half of the throwing blade is mirrored on the transverse axis. This creates a throwing vane, the base plate of which is not inclined forwards or backwards in relation to the direction of rotation of the guide disc wheel, but is inclined laterally at an angle. The angle at which the throwing blade is arranged in relation to the tangent to the guide disc wheel is 90 °. The plane that forms the blade plane with the direction of rotation of the guide disc wheel no longer runs at 90 °, but at an angle that deviates from 90 °. This results in the enlarged jet area if successive throwing blades of the same structure are installed at supplementary angles.

Besonders einfach und vorteilhaft ist die Wurfschaufel ausgebildet, wenn in Ausgestaltung der Erfindung jede Wurfschaufel im Querschnitt die Form eines liegenden Z aufweist.The throwing blade is particularly simple and advantageous if, in an embodiment of the invention, each throwing blade has the shape of a lying Z in cross section.

Eine bei der Erfindung verwendete Wurfschaufel 1 besteht im wesentlichen aus einer rechteckigen schräg angeordneten Grundplatte 2, deren beide Seiten als Strahlmittellauffläche dienen. An jeder Längskante weist die Grundplatte 2 einen rippenförmigen Seitenrand 3 auf. Der Querschnitt der Wurfschaufel 1 bildet ein liegendes Z. Der Neigungswinkel, unter dem die Grundplatte 2 zur Senkrechten zwischen den Seitenrändern 3 verläuft, ist größer als 0 bis 15 . In der in Fig. 1 bis 3 dargestellten Ausführung beträgt der Neigungswinkel 7°, in der in Fig. 4 bis 6 dargestellten Ausführu-ng 15°. In einer mittig verlaufenden Querachse A-A - zugleich Schnittlinie - weist jeder Seitenrand 3 zumindest eine Ausnehmung 4 auf, die im wesentlichen halbkreisförmig ausgebildet ist. Die Ausnehmung 4 dient der Befestigung der Wurfschaufel an einem Leitscheibenrad. Die Vierfachverwendung der Wurfschaufel ist sowohl bei einer - Ausführung Fig. 4 bis 6 - als auch bei zwei Ausnehmungen - Ausführung Fig. 1 bis 3 - gegeben. Die rippenförmigen Seitenränder 3 sind an den Stirnseiten der Wurfschaufel 1 und den Ausnehmungen benachbart mit nach außen weisenden Verstärkungsrippen 5 versehen.A throwing scoop 1 used in the invention essentially consists of a rectangular, obliquely arranged base plate 2, the two sides of which serve as a blasting agent running surface. The base plate 2 has a rib-shaped side edge 3 on each longitudinal edge. The cross section of the throwing blade 1 forms a lying Z. The angle of inclination at which the base plate 2 extends to the vertical between the side edges 3 is greater than 0 to 15. In the embodiment shown in FIGS. 1 to 3, the angle of inclination is 7 °, in the embodiment shown in FIGS. 4 to 6 it is 15 °. In a central transverse axis A-A - at the same time a section line - each side edge 3 has at least one recess 4 which is essentially semicircular. The recess 4 is used to attach the throwing blade to a guide disc wheel. The quadruple use of the throwing shovel is given both in the case of one embodiment (FIGS. 4 to 6) and in the case of two recesses — the embodiment of FIGS. 1 to 3. The rib-shaped side edges 3 are provided on the end faces of the throwing blade 1 and the recesses adjacent with reinforcing ribs 5 pointing outwards.

Die Wurfschaufel 1 ist bezogen auf ihre Querachse A-A spiegelsymmetrisch, bezogen auf ihre Längsachse B-B drehsymmetrisch ausgebildet: Die rechte - oder linke - Hälfte der Wurfschaufel entsteht, wenn die jeweils andere Hälfte um die Längsachse B-B um 180° gedreht wird; unter Beibehaltung der Bedingung, daß die obere oder untere Hälfte der Wurfschaufel durch Spiegelung der jeweils anderen Hälfte an der Querachse A-A entsteht.The throwing blade 1 is mirror-symmetrical with respect to its transverse axis AA, and with rotational symmetry with respect to its longitudinal axis BB: the right - or left - half of the throwing blade is formed when the other half is rotated through 180 ° about the longitudinal axis BB; while maintaining the condition that the upper or lower half of the throwing paddle by mirroring the respective the other half on the transverse axis AA.

Jede beschriebene Wurfschaufel kann in vier verschiedenen Einbaulagen eingesetzt werden. Das ergibt paarweise gleiche anstelle von vier gleichen Wirkungsweisen.Each throwing shovel described can be used in four different installation positions. This results in the same effects in pairs instead of four in the same way.

Die Wurfschaufeln sind an dem Leitscheibenrad so befestigt, daß zyklisch nach je einer Schaufel mit im Querschnitt liegenden Z eine Schaufel mit im Querschnitt liegenden gespiegelten Z angeordnet ist. Daraus resultiert die Verbreiterung des Strahlbereichs. Abnutzungen können durch Umsetzen in die bezogen auf das Leitscheibenrad gleiche Lage ausgeglichen werden.The throwing vanes are fastened to the guide disk wheel in such a way that a blade with Z in cross section is arranged cyclically after each blade with Z lying in cross section. This results in the broadening of the beam area. Wear and tear can be compensated for by moving to the same position in relation to the guide pulley wheel.
