Mikrowellen-Erwärmungsverfahren Zusatz zu P 33 41 585.ΑMicrowave heating process Addition to P 33 41 585.Α
In der Hauptanmeldung wurde eine Anordnung angegeben zur Erzielung von Erwärmung durch Mikrowellen unter Druck, wobei die Energie durch druckdichte Fenster in einen metallisch verschließbaren Arbeitsraum eingestrahlt wird und die Dichtung gegen das Wasserdampf-Luftgemisch sowie; gegen Strahlungsaustritt an der Öffnungslinie in einer Ebene ver- ■ laufen.In the main application an arrangement was specified for achieving heating by microwaves under pressure, whereby the energy is radiated through pressure-tight windows into a metal, lockable work space and the seal against the water vapor-air mixture and; against radiation exit at the opening line in one plane to run.
Die vorliegende Anmeldung führt in die bisher praktisch ebenflächig aufgebaute Apparatur die ZirkularsymmettHe ein unter Beibehaltung der wesentlichen physikalischen Gesichtspunkte. D. h., die Wand des Arbeitsraumes wird zu einem Metallzylinder, in den symmetrisch in laufender Folge die Fenster für die einzelnen Sender eingeschnitten sine. Die Dichtungsplatte wird ein Plastikzylinder, dicht in c'en Metallzylinder eingepaßt, durch den die Objekte lose, in ihren Originalverpackungen oder in Sonderbehältern durch cie Felder der Sender hindurch geschoben werden. Am Anfang und Ende der Rohre befindet sich je eine Druckschleuse. In einer anderen Ausführungsform laufen die Objekte in einem vorzugsweise zylindrischen Behälter, der sich wie ein hohler Kolben mit Dichtungsringen in dem Plastikrohr bewegt, an einer Seite zum Füllen und Entnehmen offen ist, mit seinen beiden Nachbarn mechanisch flexibel gekoppelt ist und am Ende vor Austritt an die freie Luft durch eine KUhlzone läuft zur Herabsetzung Von Temperatur und Druck.The present application introduces the circular symmetry into the apparatus, which has hitherto been practically constructed with a flat surface while maintaining the essential physical aspects. That means, the wall of the working space becomes a metal cylinder, in which the Sine cut windows for the individual channels. The sealing plate becomes a plastic cylinder, sealed in a metal cylinder fitted, through which the objects loose, in their original packaging or in special containers through cie fields the transmitter can be pushed through. There is a pressure lock at the beginning and end of the pipes. In another Embodiment run the objects in a preferably cylindrical container, which is like a hollow piston moved with sealing rings in the plastic tube, is open on one side for filling and removal, with its two neighbors is mechanically flexibly coupled and at the end runs through a cooling zone before it escapes into the open air to reduce it Of temperature and pressure.
Dadurch läßt sicn die Apparatur durch Wiederholung der Bauelemente zu Durchlaufofen beliebiger Kapazität ausbauen.This allows the apparatus to be repeated by repeating the components expand to a continuous furnace of any capacity.
In Abb. 1 trägt ein Metallrohr 19 Fensterausschnitte 20 regelmäßig verteilt, in die aus früher (z. B. P 33 33 >95.4) geschilderten Senderanordnungfeu Mikrowellenenergie ein gestrahlt wird. Dicht geschlossen in ciiesem Metallrohr s eckt ein Plastikrohr 21 hoher elektrischer Güte und mechanischer Festigkeit, das die b'ensteröffnunger druckdicht abdeckt, wenn in diesem Plastikrohr ein Betriebsdruck von 2-3 atü entsteht.In Fig. 1, a metal tube 19 carries window cutouts 20 regularly distributed, in those from earlier (e.g. P 33 33> 95.4) Transmitter arrangement described for microwave energy is radiated will. A plastic tube 21 of high electrical quality and mechanical quality sits tightly closed in this metal tube Strength that covers the window opening pressure-tight, if there is an operating pressure of 2-3 atü in this plastic tube arises.
In diesem Plastikrohr laufen Behälter aus dem gleichen oder ähnlichen Material. Ihre Form zeigt z. B. Abb. 2. Ein zylindrischer Behälter, an einer Längsseite offen zum Einfüllen und Entnehmen des Objektes.Containers made of the same or similar material run in this plastic tube. Their shape shows z. B. Fig. 2. A cylindrical Container, open on one long side for filling and removing the object.
An beiden Enden sind Führungsringe 22 aus Metall oder plastischem Material, die gegebenenfalls auch eine Dichtung längs des Plastikrohres gegen den Betriebsdruck des entstehenden Wasser-Dampf-Luft-Gemiisches darstellt*.At both ends there are guide rings 22 made of metal or plastic material, which may also have a seal along the plastic tube against the operating pressure of the resulting water-steam-air mixture *.
Bei Metallringen muß die Polarisation des MW-Feldes senkrecht gegenüber den Ringebenen ausgerichtet sein.In the case of metal rings, the polarization of the MW field must be aligned perpendicular to the ring planes.
Für den Betrieb gibt es zwei Ausführungsformen: Am Füllende und am Entnahmeende gibt es je eine Druckschleuse 23 mit z. B. Drehschieber. Das Objekt verträgt beim Einfahren den sofort einsetzenden überdruck von außen, aber nicht den stehenbleibenden überdruck von innen am Ende der Prozedur. Daher ist der Schleuse am Ende noch ein Kühlvorgang angeordnet, der das Objekt auf passende Temperatur und damit Druck herunterkühlt. In diesem Fall haben die Ringe nur Führungsfunktion.There are two types of operation: there is a pressure lock at the filling end and at the removal end 23 with z. B. rotary valve. The object can withstand the immediate overpressure from the outside when it is driven in, but not the permanent overpressure from the inside at the end of the procedure. Therefore, the lock is still a cooling process at the end arranged, which cools the object down to a suitable temperature and thus pressure. In this case they have Rings only guide function.

lichen Betrieb eingerichtet. Der vom Objekt und seiner feuchten Umgebung unter dem Einfluß der Energieeinstrahlung ausgehende Druck wird im wesentlichen auf die Behälter beschränkt, die Druckschleusen fallen weg, der Kühlraum vor dem Ausgang bleibt und ist so lang ausgebaut, daß die KUhlzeit erreicht wird. Die Behälter kommen dann an die offene Atmosphäre und werden ent- und beladen und schließen sich in bogenförmigem offenen Rücklauf gtführt wieder in die Apparatur ein. Zu diesem Zwecke sind die Behälter mechanisch flexibel (24) miteinander in endloser Keite gekoppelt. Der Druck in Kettenmitte gleicht sich im MitV.el in Längsspannungen aus. Der mechanische Antrieb erfolgt z. B. über symmetrisch auf 25 greifende Zahnräder mit überbrückung der Führungsringe. established operation. That of the object and its damp environment under the influence of energy radiation The outgoing pressure is essentially limited to the container, the pressure locks are eliminated and the cooling room remains in front of the exit and is developed so long that the cooling time is reached. The containers then come to the open atmosphere and are unloaded and loaded and close in an arc-shaped open return flow leads back into the Apparatus on. For this purpose, the containers are mechanically flexible (24) coupled to one another in an endless Keite. Of the Pressure in the middle of the chain is balanced out in the MitV.el in longitudinal tensions. The mechanical drive takes place z. B. about symmetrical on 25 meshing gears with bridging of the guide rings.
Je nach vorliegender Aufgabe lassen sich Kombinationen der vorgeführten Beispiele sinnvoll zusammenstellen.Depending on the task at hand, combinations of the examples presented can be put together in a meaningful way.
