Description

Verfahren zur Erzeugung von Metallstaub aus flüssigem Metall Die Erfindung betrifft ein Verfahren zur Erzeugung von Metallstaub aus flüssigem Metall, bei dem dem-flüssigen Metall m einer zu -einer Zerstäuberdüse führenden Leitung vor seinem Austritt aus der Düse Druckgas zugeführt wird. Derartige Verfahren sind bereits bekannt, doch haben dieselben den Nachteil, daß bei ihrer Anwendung das flüssige Metall durch das Druckgas nicht genügend fein zerstäubt wird, um z. B. als. ein gut brauchbares Füll- oder Schwebemittel bei der Erzeugung und dem Verbrauch von Farben zu dienen.Method of generating metal dust from liquid metal The invention relates to a method for generating metal dust from liquid metal, in which the liquid metal in a line leading to an atomizer nozzle in front of his Compressed gas is supplied to the outlet from the nozzle. Such procedures are already in place known, but they have the disadvantage that when they are used the liquid Metal is not atomized finely enough by the pressurized gas, in order to z. B. as. a well usable filler or suspending agent in the production and consumption of Colors to serve.

Diesen Nachteil zu beheben, ist der Zweck des die Erfindung bildenden Verfahrens. Gemäß demselben erfolgt die Zuführung des Druckgases an zwei oder mehreren in der Strömungsrichtung, des Metalls hintereinanderliegenden Stellen. Auf diese Weise wird der flüssige Metallstrahl stärker aufgelockert, als dies mit Hilfe bekannter Verfahren möglich war. Somit muß auch eine feinere Zerstäubung des flüssigen Metallstrahles bei, seinem Eintritt in die Zerstäuberdüse eintreten.To remedy this disadvantage is the purpose of what constitutes the invention Procedure. According to the same, the supply of the compressed gas takes place at two or more in the direction of flow, the metal one behind the other. To this The liquid metal jet is loosened up more than with the help of known ones Procedure was possible. A finer atomization of the liquid metal jet must therefore also be achieved at, its entry into the atomizing nozzle.

Eine Vorrichtung zur Ausführung des Verfahrens gemäß der Erfindung ist auf der Zeichnung dargestellt.An apparatus for carrying out the method according to the invention is shown on the drawing.

Im luftdicht abschließbaren Behälter a befindet sich der unter Druck stehende flüssige Bleikörper b. Mit dem Behälter a ist eine Spritzdüse c verbunden, deren Kanal e das flüssige Blei nach dem Düsenmund f leitet. In den flüssigen Körper b ragt ein Rohr g hinein, welches diesem Bleikörper b in geeigneter Menge, und zwar in der Weise Luft zuführt, daß diese mit dem flüssigen Blei in den Düsenkanale gelangt und zum Düsenkopf getrieben wird. Die Zuführung weiterer Luft zum flüssigen Blei wird .außerdem durch ein an der Düse c endigendes Rohr h bewirkt. Letzteres mündet gemäß Abb. 2 in ,eine die Düse c luftdicht !umschließende Kapsel i und befördert die eingeführte Luft durch in der Düse c vorgesehene Rillen h und von letzteren nach dem Kanal e führenden Bohrungen m in das im Kanal e dem Düsenkopf f zuströmende flüssige Metall, dasselbe von neuem auflockernd. The pressurized liquid lead body b is located in the airtight container a. A spray nozzle c is connected to the container a, the channel e of which guides the liquid lead to the nozzle mouth f. A pipe g protrudes into the liquid body b and supplies this lead body b in a suitable amount, namely in such a way that it gets into the nozzle channels with the liquid lead and is driven to the nozzle head. The supply of further air to the liquid lead is also effected by a tube h ending at the nozzle c. The latter opens according to Fig. 2 in a nozzle c airtight! I enclosing capsule and conveys the air introduced through c in the nozzle provided grooves h and the latter leading to the channel e bores m in the in the channel e f the nozzle head inflowing liquid Metal, loosening up the same again.
