Description
Metallteile können mittels Sandstrahlgebläse am vorteilhaftesten gerieinigt werden, wenn der Sandstrahl möglichst senkrecht auf die zu reinigende Fläche auftrifft. Bei unzugänglichen Flächen, z. B. Innenflächen von langen Rohren usw., ist dies mit den Strahldüsen der bekannten Ausführungen schwierig, da der Sandstrahl nur schräg auf die Fläche auftreffen kann, wodurch viel Energie desMetal parts can best be cleaned using a sandblasting blower, when the sandblast hits the surface to be cleaned as vertically as possible. With inaccessible Areas, e.g. B. inner surfaces of long pipes etc., this is with the jet nozzles the known designs difficult because the sandblast only hits the surface at an angle can hit, creating a lot of energy of the
ίο Sandstrahls verlorengeht. Außerdem sammelt sich bei winkligen Stellen der Sand oft in störender Menge an. Es ist · schon vorgeschlagen worden, die Strahldüse am Ende umzubiegen, um hierdurch den Strahl in der gewünschten Richtung abzulenken. Doch wird bei den bisher bekannten Düs.en dieser Art dem Sandstrahl ein großer Widerstand entgegengesetzt und der den Strahl umlenkende Teil der Düse sehr schnell abgenutzt.ίο sandblast is lost. Also collects The sand often builds up in an annoying amount at angled places. It is already proposed to bend the jet nozzle at the end in order to deflect the jet in the desired direction. But will With the nozzles of this type known up to now, there is a great resistance to the sandblasting and the part of the nozzle that deflects the jet wears out very quickly.
Gemäß der Erfindung werden die erwähnten Nachteile dadurch vermieden, daß der Sand und die Druckluft der Winkeldüse in getrennten Leitungen zugeführt werden, wobei die Luftzuführung nur einseitig zur Ablenkwand im Knie erfolgt, um den ganzen treibenden Luftstrom zur Ablenkung und Polsterung an der zu schützenden Wand auszunutzen. Das Druckluftrohr mündet in das Sandrohr an der Außenseite des von diesem gebildeten Knies derart ein, daß der Sandstrahl durch den Luftstrom die beim Austreten aus der Düse erforderliche Richtung erhält.According to the invention, the disadvantages mentioned are avoided in that the Sand and the compressed air of the angled nozzle are fed in separate lines, whereby the air supply is only on one side to the deflector wall in the knee, in order to use the entire driving air flow for deflection and cushioning on the wall to be protected. The compressed air pipe opens into the sand pipe on the outside of this formed knee in such a way that the sandblast through the air flow when exiting direction required from the nozzle.
Die Zeichnung stellt ein Ausführungsbeispiel des Erfindungsgegenstandes dar. Das Sandrohr 1 und das Rohr 2 für die Druckluft sind übereinander gelagert. An dem abgebogenen Ende der Düse tritt die Druckluft von der Seite in das Sandrohr ein und lenkt dadurch den Sandstrahl in die gewünschte Richtung um; dabei wird dem Sandstrahl kein wesentlicher Reibungswiderstand !entgegengesetzt und die Geschwindigkeit der Sandkörner nicht beeinträchtigt. Die Vorteile der Erfindung liegen darin, daß das Reinigen von unzugänglichen Stellen wesentlich beschleunigt und an Energie gespart wird.The drawing represents an embodiment of the subject matter of the invention Sand pipe 1 and the pipe 2 for the compressed air are stored one above the other. At the bent one At the end of the nozzle, the compressed air enters the sand pipe from the side and thereby directs the sand jet into the desired position Direction around; there is no significant frictional resistance opposed to the sandblast! and does not affect the speed of the sand grains. The advantages of the invention lie in the fact that the cleaning of inaccessible places significantly accelerates and energy is saved.
