Description

Vorrichtung zur kontinuierlichen Herstellung von Schießpulvern und Treibsätzen Organische Nitrate bzw. Nitrokörper bilden den Hauptbestandteil von Schießpulvern und Treibsätzen, wobei z. B. bei der Grundmasse ?\Titrocellulose in Kombination mit dieser andere treibkräftige Zusätze verwendet werden. Als solche Zusätze kommen in Betracht z. B. @\Titroglycerin und/oder Diglykoldinitrat, Nitroisobutylglycerin, Nitropenta, Hexogen, Nitrouanidin und Ammoniumnitrat. Ferner werden Weichtnacher und Stabilisatoren zugesetzt. Diese Zusätze werden in die Grundmasse hineingearbeitet, wobei mannigfaltige Einzelverfahren Verwendung finden. So wird z. B. hei der Herstellung dieser Pulver und Treibsätze aus der Grundmasse Nitrocellulose die im "Wasser aufgeschlämmte Nitrocellulose mit Sprengöl -elatiniert, wobei denn die weiteren Zusätze nach :@bscheidung des Wassers mittels gesonderter Vorrichtungen eingearbeitet werden. Bei alkoholfeuchter \itrocellulose, die durch Verdrängung des Wassers mittels Alkohol in einer Zentrifuge gewonnen wird, Igibt man diese in ein Knetwerk unter Hinzufügung eine: Lösungsmittels, z. B. Äther oder Aceton. Hierbei wird die Nitrooellulose plastifiziert und muß dann in einem gesonderten Arbeitsgang in einer Strangpre:se geformt werden. -Nach dein Trocknen werden die Formlinge durch eine Schneidemaschine in die l;ewünschte Länge geschnitten.Device for the continuous production of gunpowder and Propellants Organic nitrates or nitro bodies form the main component of Gunpowder and propellants, where z. B. with the base mass? \ Titrocellulose in Combination with this other driving force additives can be used. As such Additions come into consideration z. B. @ \ Titroglycerin and / or diglycol dinitrate, nitroisobutylglycerin, Nitropenta, Hexogen, Nitrouanidine and Ammonium Nitrate. There will also be soft nippers and stabilizers added. These additives are worked into the base mass, whereby diverse individual processes are used. So z. B. hot manufacturing this powder and propellants from the basic mass nitrocellulose which is slurried in the "water" Nitrocellulose -elatinated with explosive oil, with the other additives after: @decision of the water can be incorporated using separate devices. With alcohol damp \ itrocellulose, which is produced by displacing the water with alcohol in a centrifuge is obtained, it is put into a kneader with the addition of a: solvent, z. B. ether or acetone. Here, the nitrocellulose is plasticized and must then be formed in a separate operation in an extrusion press. -After yours The briquettes are dried to the desired length by a cutting machine cut.

l-Ian hat auch schon vorgeschlagen, vorgelatinierte N i trocellulose in Schnitzelform in geheizte Schneckenpressen einzuführen, um zu plastifizieren, wobei aus der l-Matrize der Schneckenpresse die \ itrocellulose in den gewünschten Profilen als endloser Strang austritt.l-Ian has also suggested pregelatinized nitrocellulose to be introduced in the form of chips into heated screw presses in order to plasticize, from the l-die of the screw press the \ itrocellulose into the desired Profiles emerges as an endless strand.

Ferner ist auch ein Verfahren zur Herstellung von r:iucliscliwacliem Pulver ohne Lösungsmittel bekanntgeworden, bei dem das Wasser aus der Pulverrohni<isse mittels einer Schneckenpresse mit Seiber möglichst weitgehend abgepreßt wird.Furthermore, there is also a method for producing r: iucliscliwacliem Powder without solvent became known, in which the water from the powder tube isse is squeezed as much as possible by means of a screw press with a strainer.

Bei den genannten Verfahren und Vorrichtungen sind aber immer nur einzelne, voneinander getrennte @"; rarlieittingsstufen vorhanden, d. b. daß an verschiedenen Stellen während einer längeren Zeit immer wiederkehrende Gefahren von Bränden und Explosionen vorhanden sind, die nicht mir durch die Pulvermassen selbst, sondern vorwiegend durch die unkontrollierbaren Verluste von Lösungsmitteln, so z. B. Äther, bedingt sind. Ein vollautomatisches Arbeitsverfahren setzt aber eine vollkommen kontinuierlich arbeitende, einheitliche und abgeschlossene Vorrichtung zur Herstellung von Pulvern und Treib-:ätzen voraus.In the above-mentioned methods and devices, however, are always only individual, separate @ "; rarlieitting stages present, d. b. that an recurring dangers in various places over a long period of time of fires and explosions are present that are not mine due to the masses of powder itself, but mainly through the uncontrollable loss of solvents, so z. B. ether, are conditional. However, a fully automatic work process is in place a completely continuous, uniform and self-contained device for the production of powders and propellant: etching ahead.

Die erfindungsgemäße Vorrichtung zur konstanten Herstellung von geformten Schieß- und Treibmitteln mit oder ohne Verwendung von Lösungsmitteln und unter Anwendung von Schneckenpressen zeichnet sich dadurch aus, daß sie aus einer einzigen seilierlosen Doppel- oder Mehrspindelschneckenpresse besteht. die mindestens je zwei abwechselnd aufeinanderfolgende drucklose und druckerzeugende Zonen aufweist und die letzte Druckzone in einer oder mehreren Formdüsen endet. Der Wassergehalt dieser Pulver-und Treibsätze wird hierbei unter 7%- herunterl;esetzt, so daß durch diese Vorrichtung Pulver- und Treibsätze erhalten werden, die nur 3% und noch weniger Wasser enthalten.The inventive device for the constant production of shaped Firing and propellants with or without the use of solvents and with application of screw presses is characterized by the fact that they consist of a single ropeless There is a double or multi-spindle screw press. the at least two alternately having successive pressureless and pressurizing zones and the last Pressure zone ends in one or more molding nozzles. The water content of this powder and Propellant charges are here below 7% - down, so that by this device Powder and propellant charges are obtained that contain only 3% and even less water.

An einem Beispiel wird die Vorrichtung für den Pulver- bzw. den Treibsatz ohne Lösungsmittel in Fig. 1 näher erläutert.An example is the device for the powder or propellant charge explained in more detail in FIG. 1 without solvent.

Beispiell 51 Gewichtsteile wasserfeuchter Nitrocellulose werden aus dem Behälter 1 über die Dosiervorrichtung 2 in die Doppel- oder Mehrspindelschneckenpresse 3, und zw;ar@ in die Zone 4 eingeführt, die durch entsprechende Gestaltung der Schneckengänge drucklos ist. Die Doppel- bzw. Mehrspindelsclinecke 3 wird hierbei geheizt, und zwar bis zu einer Temperatur bis zu 85° C. Gleichzeitig mit der wasserfeuchten Nitrocellulose werden über den Behälter 5 38 Gewichtsteile ?\Titroglycerin der drucklosen Zone 4 zugeführt. Die Pulvermasse gelangt in die Schneckenzone 6, deren Schneckenspindeln druckerzeugend gestaltet sind, so daß das Wasser zurückläuft und mittels des Abflußkanals 7 abgezogen wird. Die Pulvermasse läuft nun weiter in die Schneckenpresse und gelangt wiederum in eine drucklose Zone 8 in deren Bereich über den Behälter 9 mit Dosiervorrichtung 10 Weichmacher und Stabilisatoren der Pulvermasse zugeführt werden. Im vorliegenden Beispiel ist die Dosierung derart zu führen. daß auf 51 Gewichtsteile wasserfeuchter Nitrocellulose 6 Gewichtsteile Centralit I und 5 Gewichtsteile Äthylphenylurethan zugesetzt werden. Wiederum gelangt nun die Pulvermasse mit diesen Zusätzen in eine druckerzeugende Zone 11 und tritt nunmehr aus einer Matrize oder Lochscheibe 12 mit 30;o Feuchtigkeit aus. Kleinkalibrige Röhren und Profile können sofort nach dem Schneiden in üblicher Weise getrocknet werden und sind dann gebrauchsfertig. Für größere Kaliber, wie sie bei der Feststoffraketen-Treibsatzherstellung erforderlich sind, wird die Pulvermasse durch die Lochscheibe 12 gepreßt und mittels der Schneidevorrichtung 13 geschnitzelt. Die Schnitzel durchlaufen den Trockenkanal 14, der mit einer Absaugevorrichtung 15 versehen ist. Aus dem Trockenkanal gelangen die Schnitzel sofort in die Formgebungsschnecke 16. Aus der Formgebungsmatrize 17 treten nunmehr Pulver- und Treibsatzprofile aus, deren Feuchtigkeitsgehalt unter 0,5% liegt. Beispiel II Das folgende Beispiel zeigt die Arbeitsweise der Vorrichtung für ein Pulver bzw. .einen Treibsatz mit Lösungsmittel (Fig.II).For example, 51 parts by weight of water-moist nitrocellulose are made the container 1 via the metering device 2 into the twin or multi-spindle screw press 3, and zw; ar @ introduced into zone 4, which is achieved by appropriate design of the worm threads is pressureless. The double or multi-spindle spin corner 3 is heated here, and up to a temperature of up to 85 ° C. Simultaneously with the water-moist nitrocellulose are 38 parts by weight? \ titroglycerin of the pressureless zone via the container 5 4 supplied. The powder mass reaches the screw zone 6, its screw spindles are designed to generate pressure so that the water flows back and by means of the drainage channel 7 is deducted. The powder mass now runs into the screw press and arrives again in a pressureless zone 8 in the area above the container 9 with the metering device 10 plasticizers and stabilizers are added to the powder mass. In the present example, the dosing is to be carried out in this way. that to 51 parts by weight water-moist nitrocellulose 6 parts by weight of Centralit I and 5 parts by weight of ethylphenyl urethane can be added. Again, the powder mass with these additives now arrives in a pressure-generating zone 11 and now emerges from a die or perforated disk 12 with 30; o moisture off. Small caliber tubes and profiles can be used immediately be dried in the usual way after cutting and are then ready for use. For larger calibers, such as those required for solid rocket propellant production are, the powder mass is pressed through the perforated disk 12 and by means of the cutting device 13 carved. The chips pass through the drying channel 14, which is equipped with a suction device 15 is provided. From the drying tunnel, the chips are immediately transferred to the shaping screw 16. Powder and propellant charge profiles now emerge from the shaping die 17, whose moisture content is below 0.5%. Example II The following example shows the operation of the device for a powder or .a propellant with solvent (Fig. II).

Die alkoholfeuchte Nitrocellulosewolle mit einem Wassergehalt von 900% (insgesamt 100 kg) gelangt aus dem Behälter 18 über die Dosiervorrichtung 19 in die drucklose Zone 20 der Doppel- bzw. Mehrfachspindelschnecke 21. Gleichzeitig werden hierbei 90 kg 99%iger Alkohol aus dem Behälter 22 über die Dosiervorrichtung 23 zugegeben. Die Masse gelangt in die druckerzeugende Zone 24, wobei bedingt durch den Druckaufbau die Alkohol-Wasser-Mischung über das Ablaufrohr 25 weggenommen wird. Nunmehr gelangt die Masse wiederum in eine drucklose Zone 26, wobei 90 kg 99%iger Alkohol aus dem Behälter 27 mittels Dosiervorrichtung 28 zugegeben werden. Wiederum gelangt die Masse in eine druckerzeugende Zone 29, wobei die Wasser-Alkohol-Mischung über das Ablaufrohr 30 abgelassen wird. Nachdem die Masse nunmehr nochmals eine drucklose Zone 31 erreicht, werden über den Behälter 32 und mittels Dosiervorrichtung 33 70 kg Äther zugegeben, ferner aus dem Behälter 34 mittels Dosiervorrichtung 35 10 kg Stabilisatorenzusätze eingeführt. Die Pulvermasse tritt, nachdem sie die Druckerzeugungs- und Homogenisierungszone 36 der Schneckenpresse durchlaufen hat, aus der Matrize 37 in den T.rocknungskanal 38, der mit einer Absaugevorrichtung 39 versehen ist. Aus dem Trocknungskana138 gelangt das Pulver nochmals in eine Formgebungsschnecke 40, wobei mittels Schneidevorrichtung 41 die Pulverkörper in bestimmte Längen geschnitten werden können.The alcohol-moist nitrocellulose wool with a water content of 900% (100 kg in total) passes from the container 18 via the metering device 19 into the pressureless zone 20 of the double or multiple spindle screw 21. At the same time, 90 kg of 99% alcohol are transferred from the container 22 the metering device 23 is added. The mass reaches the pressure-generating zone 24, the alcohol-water mixture being removed via the drain pipe 25 due to the pressure build-up. The mass now again arrives in a pressureless zone 26, with 90 kg of 99% alcohol being added from the container 27 by means of the metering device 28. The mass again arrives in a pressure-generating zone 29, the water-alcohol mixture being drained off via the drain pipe 30. After the mass has now again reached a pressureless zone 31, 70 kg of ether are added via the container 32 and by means of the metering device 33, and 10 kg of stabilizer additives are introduced from the container 34 by means of the metering device 35. After it has passed through the pressure generation and homogenization zone 36 of the screw press, the powder mass emerges from the die 37 into the drying channel 38, which is provided with a suction device 39. From the drying channel 138, the powder passes again into a shaping screw 40, with the powder bodies being able to be cut into specific lengths by means of the cutting device 41.

Diese erfindungsgemäße kontinuierlich arbeitende Vorrichtung kann nicht nur für die Herstellung von Pulvern und Treibsätzen auf Basis Nitrocellulose Verwendung finden, sondern auch auf Basis organischer Nitrokörper, so z. B. Tri-Dinitrotoluol. So führt dieses Verfahren im Falle der Verwendung von Nitrocellulose als Grundmass. dieser Pulver und Treibsätze von der wasserfeuchten \Titrocellulose bis zum fertigen Pulverformling, - ohne daß Unterbrechungen in den Arbeitsstufen bzw. Transporten von einer Vorrichtung zur anderen bestehen. Die Vorrichtung ist vollkommen abgeschlossen, so daß die Gefahr von Bränden und Explosionen ausgeschaltet ist, wobei gleichzeitig im Falle der Herstellung von lösungsmittelhaltigen Pulvermassen eine Wiedergewinnung der Lösungsmittel gewährleistet ist. Weiterhin werden die Gefahrenmomente beseitigt, die z. B. bei lösungsmittelhaltigen Pulvermassen in der Bildung der explosiven Lösungsmittel-Luftgemische liegen.This continuously operating device according to the invention can not only for the production of powders and propellants based on nitrocellulose Find use, but also based on organic nitro bodies, such. B. tri-dinitrotoluene. So this method leads in the case of the use of nitrocellulose as a basic measure. these powders and propellants from the water-moist \ titrocellulose to the finished product Powder molding, - without interruptions in the work stages or transports consist of one device to another. The device is completely closed, so that the risk of fire and explosion is eliminated, while at the same time in the case of the production of powder masses containing solvents, a recovery the solvent is guaranteed. Furthermore, the dangers are eliminated, the z. B. with solvent-based powder masses in the formation of explosive solvent-air mixtures lie.

Durch diese kontinuierlich arbeitende und automatisch steuerbare Vorrichtung erlangt man eine Homogenität der Pulvermassen, wie sie früher nur durch zusätzliche Operationen, z. B. durch Zwischenschaltung von Blockpressen, erreicht wurde.Through this continuously working and automatically controllable device One achieves a homogeneity of the powder masses, as it used to be only through additional Operations, e.g. B. by interposing block presses was achieved.
