Description
Bezeichnung: Mechanisierung des Spritzens von feuerfestenName: mechanization of the spraying of refractories
Stoffen und von Betonen für Bauzwecke durch maschinelle Spritzdüsenführung Die Erfindung betrifft die Vereinfachung, Vergleichmässigung und Verbesserung der Zustellung beim Spritzen von ungeformten feuerfesten Erzeugnissen oder Betonen für Bauzwecke, sowie beim Plasmaspritzen von Sonderkeramikschichten auf keramischem Grundmaterial durch Ersatz der manuellen Spritzdüsenführung zu Gunsten eines maschinellen, automatisierten Vorganges mit Hilfe eines sogenannten Drehzylinders oder eines ahnlich arbeItenden Gerätes. Materials and concretes for building purposes through mechanical spray nozzle guidance The invention relates to the simplification, uniformity and improvement of Infeed when spraying unshaped refractory products or concretes for Construction purposes, as well as the plasma spraying of special ceramic layers on ceramic Basic material by replacing the manual spray nozzle guide in favor of a mechanical, automated process with the help of a so-called rotary cylinder or a similar one working device.
Spritzen findet vorwiegend im Berg- und Tunnelbau mit Baubetonen und in der Sisen- und Stahlindustrie, Zement-und petrochemischen Industrie mit ungeformten feuerfesten Erzeugnissen Anwendung. Für die Feuerfestanwendung kommt zusätzlich die Möglichkeit des Auftragens auf heiße Flächen, das Heißspritzen hinzu. Das Plasmspritzen refraktärer Materialien auf keramisches Grundmaterial ist in der Entwicklung. Bei allen Vorzügen des Spritzens haftet diesem aufgrund vieler gleichzeitig einwirkender unkontrollierter Einflußgrößen Subjektivität und Ungleichmässigkeit an. Die Düsenfülirung erfolgt bis auf Ausnahmen allgemein trotz der Staubentwicklung noch von Hand durch den Düsenführer: Dieser hält die Spritzdiase in der Hand und bewegt sie zum Auftragen des Spritzgutes auf und ab oder hin und her, teilweise auch noch überlagert mit kreisförmigen Drehbewegungen. Trotz allen handwerklichen Könnens beinhaltet dies eine Fülle subjektiver Beeinflussungsmöglichkeiten.Spraying is mainly used in mining and tunnel construction with building concrete and in the iron and steel industry, cement and petrochemical industries with unshaped refractory products application. For refractory applications there is also the possibility of applying to hot surfaces, adding the hot spraying. The plasma spray Refractory materials based on ceramic base material are under development. at All the advantages of spraying are adhered to due to the many simultaneous effects uncontrolled influencing variables subjectivity and unevenness. The nozzle filling is generally carried out by hand, with a few exceptions, despite the formation of dust the nozzle operator: He holds the spray nozzle in his hand and moves it to apply of the material to be sprayed up and down or back and forth, sometimes also superimposed with circular rotary movements. Despite all craftsmanship, this includes an abundance of subjective influencing possibilities.
Gegenstand der Erfindung ist es, die Düsenführung von Hand durch einen geeigneten maschinellen Vorgang abzulösen. Hierbei soll mit Hilfe eines gleichmässig arbeitenden, möglichst kompakten Gerätes eine reversierende partielle Drehbewegung um einen festen Ort in Anlehnung an das Hin- und Herbewegen der Düse durch den Düsenführer erfolgen. Hierzu haben sich in den eigenen Versuchen sogenannte Drehzylinder aus der Pneumatik- und Hydrauliktechnik als besonders geeignet erwiesen. Beim Drehzylinder wird die Bewegung eines im Zylinder von einem zum anderen Ende hin- und herwandernden Doppelkolbens iiber eine Zaimstange auf ein Ritzel übertragen; die Drehbewegung des Ritzels wird dabei direkt oder über ein Getriebe auf eine sich hierdurch drehende Welle übertragen.The object of the invention is the nozzle guide by hand by a to replace suitable mechanical process. This should be done with the help of an evenly working device, which is as compact as possible, a reversing partial rotary movement a fixed location based on the nozzle operator moving the nozzle back and forth take place. For this purpose, so-called rotary cylinders have proven themselves in our own experiments proven to be particularly suitable in pneumatic and hydraulic engineering. With the rotary cylinder becomes the movement of one moving back and forth in the cylinder from one end to the other Transferring the double piston to a pinion via a rack; the rotary motion of the pinion is directly or via a gear on a rotating thereby Transmit wave.
In Fig. 1 ist die Schnittzeichnung eines solchen Gerätes dargestellt.In Fig. 1 the sectional drawing of such a device is shown.
Fig. 2 zeigt ein solches Gerät mit angeflanschter Spritzdüse.Fig. 2 shows such a device with a flange-mounted spray nozzle.
Die Drehgeschwindigkeit wird durch Druck und Menge der in und aus dem Zylinder fließenden Druckluft gesteuert. Die Größe des Drehwinkels kann durch den Hub des Kolbens mit Hilfe pneumatischer Endschalter innerhalb des maschinentechnisch möglichen Bereiches verändert werden.The speed of rotation is determined by the pressure and amount of going in and out compressed air flowing through the cylinder. The size of the angle of rotation can be by the stroke of the piston with the help of pneumatic limit switches within the machine possible range can be changed.
Für das Spritzen größerer Belder,werden die Spritzachichten übereinander oder nebeneinander aufgetragen. Hierzu wird der Drehzylinder auf eine seitlich sowie höhenbeweglich arbeitende Halterung montiert.For the spraying of larger belder, the spray layers are on top of each other or applied side by side. To do this, the rotary cylinder is on a side as well Mounted bracket that can move in height.
In Fig. 3 ist als Beispiel hierzu die höhenbewegliche Vorrichtung mit Hilfe pneumatisch betriebenen Druckluftzylinders dargestellt. In diesem Fall führt die Spritzdüse partielle Drehbewegungen um die lotrechte Achse aus, und der Hubzylinder kann kontinuierlich oder schrittweise auf und ab bewegt werden. Alternativ können ebenso Teleskoparme verwendet werden.In Fig. 3 is an example of this, the vertically movable device shown with the help of pneumatically operated compressed air cylinder. In this case performs the spray nozzle partial rotary movements around the vertical axis, and the Lifting cylinder can be moved up and down continuously or in steps. Alternatively Telescopic arms can also be used.
Zur maschinellen Düsenführung liegen bisher nur beim Heißspritzen ungeformter feuerfester Erzeugnisse Unterlagen über kreisiörmiges Drehen der Düse um die Symetrieachse kreisrunder Gefäße vor (1 bis 3). Hierbei wird die Düse kontinuierlich angehoben oder abgeseiikt. Die eigene Erfindung betrifft auch die autorlatisierte Zustellung von ebenen Flächen.So far, only hot spraying has been used for machine nozzle guidance unshaped refractory products documents on circular rotation of the nozzle around the axis of symmetry of circular vessels (1 to 3). Here the nozzle becomes continuous raised or dropped. The own invention also relates to the authorized one Delivery of flat surfaces.
