Description
ZusammenfassungSummary
Bei der Erfindung handelt es sich um eine Strahldüse für Abrasivpartikel zur Oberflächenbearbeitung, die geometrisch so gestaltet ist, dass zwecks Bindung der entstehenden Stäube, um die Strahldüse ein Wassermantel gelegt wird.The invention relates to a jet nozzle for abrasive particles for surface treatment, which is geometrically designed so that a water jacket is placed around the jet nozzle in order to bond the resulting dusts.
Beschreibungdescription
Das Strahlen mit Hilfe von Abrasivpartikeln ist ein Oberflächenbearbeitungsverfahren, das hauptsächlich zum Reinigen von Oberflächen oder zur Modifizierung der Oberflächenstruktur für anwendungsspezifische Zwecke dient. Das konventionelle Strahlverfahren erfolgt nach dem Venturi-, Druckstrahl-, Schleuderrad- oder dem Rotationsdüsen-Prinzip. Zum Einsatz kommen dabei Strahlmittel wie Quarzsand, Stahlkugeln, Glasperlen, etc. je nach Aufgabenstellung und dem zu bearbeitenden Werkstoff.Abrasive particle blasting is a surface treatment process that is primarily used to clean surfaces or to modify surface texture for application specific purposes. The conventional blasting method is based on the venturi, pressure jet, blast wheel or rotary nozzle principle. Blasting agents such as quartz sand, steel balls, glass beads, etc. are used depending on the task and the material to be processed.
Das Strahlverfahren wird in fast allen Industriebereichen eingesetzt, u. a. Maschinen- und Apparatebau, Fahrzeugbau, Gerätetechnik, Chemischer Anlagenbau, Nahrungsmittel-Maschinen, Sportartikel, Medizintechnik, etc. In der Regel werden komplexe Bauteile bearbeitet, die eine bestimmte Funktionsoberfläche erhalten sollen, Dabei werden teilweise Werkstoffe bearbeitet, die hochgiftig und umweltschädlich sind. Zum Teil sind auch Sanierungsarbeiten durchzuführen, bei denen hochgiftige Schutzschichten entfernt werden und dabei die alleinige Absaugung der prozessbedingt entstehenden Stäube nicht ausreicht, und daher über Nassabscheider aufwendig gefiltert und gebunden werden müssen. Dabei lässt sich eine Reststaubentweichung nie ganz verhindern. Im Falle von Außenarbeiten ist jedoch eine Entstaubung nicht möglich, so dass die Umwelt erheblich belastet wird.The blasting process is used in almost all industrial sectors, including: a. Machine and apparatus construction, vehicle construction, equipment technology, chemical plant construction, food processing machinery, sporting goods, medical technology, etc. As a rule, complex components are processed, which are to receive a specific functional surface, It is partially processed materials that are highly toxic and harmful to the environment. In some cases, rehabilitation works are carried out in which highly toxic protective layers are removed and thereby the sole extraction of dusts caused by the process is not sufficient, and therefore need to be filtered through wet scrubbers and bound extensively. A residual dust leak can never be completely prevented. In the case of external work, however, a dedusting is not possible, so that the environment is significantly burdened.
Man versuchte das Problem dadurch zu lösen, dass man gemäß der prinzipiellen Darstellung in
Dieser grundsätzliche Mangel lässt sich erfindungsgemäß dadurch beseitigen, dass um den Abrasivstrahlkegel statt des Luftmantels oder ergänzend zum Luftmantel ein Wassermantel aus feinsten Tröpfchen gelegt und so die Stäube an der Entstehungsstelle gebunden werden. Die feinen Wassertröpfchen werden ohne Zerstäuberluft erzeugt und zwar mit Hilfe einer Hochdruckpumpe und mittels Drall-Zerstäuberdüsen.This fundamental defect can be eliminated according to the invention by placing a water jacket of very fine droplets around the abrasive cone instead of the air jacket or in addition to the air jacket, thus binding the dusts at the point of origin. The fine water droplets are generated without atomizing air, using a high pressure pump and spin atomizing nozzles.
Die Gestaltung der Abrasivstrahldüse gemäß der prinzipiellen Darstellung in
Eine weitere Verbesserung der Staubbindung beim Abrasivstrahlen lässt sich erzielen, wenn die prinzipiellen Anordnungen gemäß
