Vorrichtung zur kontinuierlichen Herstellung von Schiess-und Treibmitteln
Gegenstand des Sta. mmpatentes Nr. 214329 ist eine Vorrichtung zur kontinuierlichen Herstellung von Schiess- und Treibmitteln mit oder ohne Verwendung von Lösungsmitteln, gekennzeichnet durch eine Doppel-oderMehrspindel-Schneckenpresse. bei der Einspeisevorrichtungen für flüssige oder feste Zusatz- komponenten vorgesehen sein können, wobei die Presse aufeinanderfolgend eine drucklose Zone als Mischi zone, eine druckerzeugende Zone als Verdrängungs-bzw. Abscheidezone und je eine drucklose Zone als Knet-bzw. Austragszone aufweist.
Eine spezielle Ausführung dieser Vorrichtung ist dadurch gekennzeich- net, dass an die Austragszone ein geschlossener, heizbarer Kanal, der an eine Absaugvorrichtung ange- schlossen werden kann, und eine Formgebungsschnecke anschliesst, hinter deren Mundstück eine Schnei- devorrichtung vorgesehen ist.
Die Grösse des zu pressendenPulverstranges ist dabei massgeblich bestimmt durch den Durchmesser der
Schneckenspindel der Formgebungsschnecke. Wird als Formgebungsschnecke eine Doppelschneckenpresse verwendet, bei der der Spindeldurchmesser z. B. 70 mm beträgt, so wird ein Pulverstrang erhalten, der nur 50 mm Durchmesser besitzt.
Erfindungsgemäss wird nun eine Vorrichtung vorgeschlagen, bei der man auch grössere Pulverstränge pressen kann, ohne die Dimensionen der Spindelschnecke zu vergrössern. Man erhält z. B. bei Verwen- dung einer 70 mm Spindelschnecke Pulverstränge bis zu 100 mm und mehr, wenn erfindungsgemäss die
Formdüse, z. B. zu einem Zylinder, verbreitert und verlängert und mit einer mit Radialschlitzen verse- henen Bremsplatte abgeschlossen ist. Diese Schlitze lassen die den Pulverstrang umgebende Luft beim Anfüllen der Düse entweichen, wobei man noch kurze Zeit auch Pulvermassen austreten lässt.
Hiedurch bleibt die Pulvermasse im Fliessen und man erhält einen formgerechten und lunkerfreien Pulverkörper. Bei kontinuierlicher Verarbeitung und Herstellung längerer Pulverkörper wird die Bremsplatte abgenommen und somit ein der grösseren Düsenöffnung entsprechender lunkerfreier Strang weiter ausgepresst, da die
Wandreibung den nötigen Widerstand zur Füllung der Düse bewirkt.
Fig. 1 zeigt eine Ausführung der erfindungsgemässen Vorrichtung. Von der Formgebungsschnecke 1 gelangt die Pulvermasse in die erweiterte und verlängerte Düse 2. Zur Beheizung dieser Düse 2 ist diese mit einem Heisswassermantel 3 versehen. Am Düsenaustritt befindet sich die Bremsplatte 4 mit Nuten.
Fig. 2 zeigt die Bremsplatte 4 in der Ansicht von hinten.

Device for the continuous production of firing and propellants
Subject of the Sta. mmpatentes No. 214329 is a device for the continuous production of shooting and propellants with or without the use of solvents, characterized by a double or multi-spindle screw press. in which feed devices for liquid or solid additional components can be provided, with the press successively having a pressureless zone as a mixing zone and a pressure-generating zone as a displacement or displacement zone. Separation zone and a pressureless zone each as kneading or. Has discharge zone.
A special embodiment of this device is characterized in that a closed, heatable channel, which can be connected to a suction device, and a shaping screw, behind the mouthpiece of which a cutting device is provided, connects to the discharge zone.
The size of the strand of powder to be pressed is largely determined by the diameter of the
Screw spindle of the shaping screw. If a twin screw press is used as the shaping screw, in which the spindle diameter z. B. 70 mm, a powder strand is obtained which has a diameter of only 50 mm.
According to the invention, a device is now proposed in which larger powder strands can also be pressed without increasing the dimensions of the spindle screw. One obtains z. B. when using a 70 mm spindle screw powder strands up to 100 mm and more, if according to the invention
Form nozzle, e.g. B. to a cylinder, widened and lengthened and finished with a brake plate provided with radial slots. These slots allow the air surrounding the powder strand to escape when the nozzle is being filled, and powder masses are also allowed to escape for a short time.
As a result, the powder mass remains flowing and one obtains a form-fitting and void-free powder body. In the case of continuous processing and manufacture of longer powder bodies, the brake plate is removed and a void-free strand corresponding to the larger nozzle opening is pressed out further, since the
Wall friction creates the necessary resistance to fill the nozzle.
1 shows an embodiment of the device according to the invention. From the shaping screw 1, the powder mass passes into the widened and lengthened nozzle 2. This nozzle 2 is provided with a hot water jacket 3 to heat it. The brake plate 4 with grooves is located at the nozzle outlet.
Fig. 2 shows the brake plate 4 in a view from the rear.
