Auf dem Gebiete der Druckstrahlsprjtzung flüssiger oder fester Körper sind bereits mancherlei Erfindungen gemächt worden, die mit Hilfe von besonderen Vorrichtungen eine wirtschaftlich nützliche Schleuderung des Spritzgutes erstreben.In the field of pressure jet spraying liquid or solid bodies, various inventions have already been made, the with With the help of special devices, an economically useful centrifugation of the spray material strive for.

Insoweit es sich um feucht aufzutragende Stoffe oder Massen handelt, hat man sich schon früher des Dampfdruckstrahls zu bedienen gesucht, der ähnlich dem in der Farbenspritztechnik angewendeten Luftdruckstrahl das Spritzgut ansaugt, trägt oder abstößt. Dieses Verfahren, mittels Dampf zu spritzen, begegnete jedoch mancherlei Schwierigkeiten, welcheIn so far as it is to be applied wet Substances or masses are involved, people have tried to use the steam pressure jet in the past, which, similar to the air pressure jet used in paint spraying, sucks, carries or pushes the sprayed material. This However, methods of spraying by means of steam encountered various difficulties, which

»5 sich einmal aus der Zuführung der erforderlichen gleichmäßigen Feuchtigkeitsmengen oder eines genügend befeuchteten Materials ergaben, dann auch daraus, daß das Spritzgut nicht immer wirksam angesaugt und ohne Störungen zur Arbeitsstelle geleitet werden konnte. Die Schaffung eines solchen, von diesen Mängeln befreiten technischen Behelfes (Dampfdruckdüse) ließ den Gedanken reifen, den als Druckmittel bereits verwendeten Dampfdruckstrahl»5 once from the supply of the required uniform amounts of moisture or of a sufficiently moistened material, then also from the fact that the spray material was not could always be effectively sucked in and conveyed to the place of work without disruptions. the Creation of such a technical aid freed from these deficiencies (steam pressure nozzle) let the thought mature, the steam pressure jet already used as a pressure medium

*5 auch noch nach anderer Richtung wirtschaftlich nutzbar zu machen.* 5 also economically in another direction to make usable.

Die im folgenden zur Darstellung gelangende Erfindung bezweckt, mit Hilfe eines aus" ein und derselben Quelle strömenden Dampfstromes nicht nur das Spritzgut zur Arbeitsfläche oder Stelle zu schleudern, sondern auch die zu seiner jeweils erforderlichen gleichmäßigen Durchfeuchtung erforderlichen Feuchtigkeitsrhengen durch ein gleichzeitiges Verdichten eines Teiles des,Dampfes zu erzeugen.
Die Erfindung ist dargestellt:The purpose of the invention, which is presented below, is not only to throw the spray material to the work surface or place with the aid of a steam stream flowing from "the same source, but also to throw the amount of moisture required for its necessary uniform moisture penetration by simultaneously compressing part of the, To generate steam.
The invention is illustrated:

in Fig. ι im Querschnitt,in Fig. ι in cross section,

in Fig. 2 -in der Rückansicht mit teilweise ausgebrochenem Deckel, ,in Fig. 2 - in the rear view with partially broken cover,

in Fig. 3 in teilweiser Ansicht der Düse von oben auf den eingelassenen Mischgutstutzen gesehen.in Fig. 3 in a partial view of the nozzle from above onto the recessed mix pipe seen.

Die Düse α wird gebildet von einem doppelwandigen Hohlkegel (Fig. i). 'The nozzle α is formed by a double-walled hollow cone (Fig. I). '

In den Boden der Düse α sind drei mit ⁴S einem Ringrohr d¹ verbundene, besonders hergestellte/ Kondensdruckdüsen d eingelassen, welche vermittels zugehöriger Mutter dichtschließend an dem Boden festgeschraubt sind. Verschlossen wird die Düse α mit dem mit Gewinde versehenen Deckel b (Fig. i). Deckel b ist zum Einlaß des Dampfes mit Stutzen c ausgerüstet, welcher mit entsprechender Bohrung und Gewinde versehen ist.Α are in the bottom of the nozzle ⁴ with three S a ring tube d ¹ connected, particularly produced / Kondensdruckdüsen embedded d, which means associated nut are sealingly bolted to the floor. The nozzle α is closed with the threaded cover b (Fig. I). Cover b is equipped with a nozzle c for the inlet of the steam, which is provided with a corresponding bore and thread.

In dem oberen Teil der Düse a, in bestimmtem Abstande von ihrem Boden, befindet sich eine von Wandungen g gebildete, quer zur Längsrichtung, der Düse α liegende längliche Öffnung zur Aufnahme des Mischgutstutzens h, der in seinem unteren Teile in Kastenform gemäß der erwähnten Öffnung ausgebildet, ist (Fig. i, 2 und 3). Mischgutstutzen h, versehen rrit Flansch und. zugehörigen Bohrungen i zwecks Befestigung und zur Aufnahme der Schrauben i¹, ist oberhalb in zylindrischer Form gehalten und für den Anschluß an die Mischgutzuführungsleitung mit einem Gewindestutzen versehen.In the upper part of the nozzle a, at a certain distance from its bottom, there is an elongated opening formed by walls g, transverse to the longitudinal direction of the nozzle α, for receiving the mixture nozzle h, which in its lower part is box-shaped according to the opening mentioned is formed (Fig. i, 2 and 3). Mixture nozzle h, provided rrit flange and. associated bores i for the purpose of fastening and receiving the screws i ¹ , is held above in a cylindrical shape and provided with a threaded connector for connection to the mixed material feed line.

Die Arbeitsweise der hier beschriebenen Dampfdruckspritzdüse ist folgende:The mode of operation of the steam pressure spray nozzle described here is as follows:

Claims

Steam in the space x formed by the double walls of the hollow cone α and kept closed by the cover b. As a result of the steam flowing out through the specially introduced holes B at the mouth of the nozzle α, an air-diluted space is formed inside the syringe, whereby the mixed material falling through the box connector h under a certain pressure arigesogen and after leaving the cavity by the pressure jet of the holes B is surrounded. The pressure jet, which can be increased as required, lets the mixed and moistened material fall onto the work surface. At the same time, the steam flows into the number of small bores B1 in the pipe ring (P-) and there, compressed, finds its way further into the nozzles d connected to this pipe ring serve to effect the mixing in of the mixed material flowing in through h. For the purpose of condensation, a double cylinder H- (Fig. 1) is let into the cylindrical part of the nozzle d in its channels i, 2, 3 and 4 of the Steam takes the path indicated by the arrow directions in the drawing, whereby it cools down from the bores of the spherically held cap f. The amounts of steam that have already condensed in channel 1 find their immediate way through the bores 2 of the wall β and through further bores 3 ″ Exit (Fig. I). Before it reaches the mouth of the nozzle α as a result of the suction effect, the mixture is absolutely necessary by means of the condensation nozzles d evenly distributed amount of condensed water. The compressed steam quantities otherwise flowing out of these nozzles reach the low 4 on their further path due to the coolness of the mixed material when it comes into contact with the same! The punch. The arrangement of the three nozzles d as well as the bores of the spherical caps f is such that the flowing water and compressed vapor form a prism open at the top into which the mixture falls, for a more even admixture on the further way ■ to learn about water. 5i patent claims:.
