Description

Anordnung zur Behandlung von Stoffen im elektrischen Hochfrequenzfeld Es ist bekannt, daß Stoffe .der verschiedensten Art, beispielsweise Holz oder P,a.pier,odier andere Stoffe mit mehr oder weniger hohen dielektrischen Verlusten im elektrischen Hochfrequenzfeld behandelt werden können. Meist wird bei dieser Behandlung die in dem Stoff durch das Ho:chfrequenzfelderzeugte Wärme ,ausgenutzt: Es wird dabei im allgemeinen mit Frequenzen über i or Hertz bzw. mit Wellenlängen in der Größenordnung zwischen i o und 5o m gearbeitet. Das zur Behandlung dienende Hochfrequenzfeld wird meist zwischen den Belegungen .eines Kondensators ,erzeugt, der :an den Hochfrequenzgenerator angeschlossen ist. In letzterem wird mit Hilfe gittergesteuerter Elektronenrohre Gleichstrom oder niederfrequenter Wechselstrom in Hochfrequenzenergie umgewandelt.Arrangement for the treatment of substances in an electrical high-frequency field It is known that substances of the most varied kinds, for example wood or P, a.pier, or other substances with more or less high dielectric losses in the electrical High frequency field can be treated. This treatment usually involves the in the material through the high frequency field generated heat, exploited: It is in the generally with frequencies above i or Hertz or with wavelengths in the order of magnitude worked between 10 and 50 m. The high frequency field used for treatment is mostly between the assignments of a capacitor that: to the high-frequency generator connected. In the latter, grid-controlled electron tubes are used Direct current or low frequency alternating current converted into high frequency energy.

Erfindungsgemäß sind die Kondensatoren, "über die der Beha,udlungskondensator an den Schwingungskreis des Generators angekoppelt ist, als Durchführungen durch .die Wand des Generatorraumes ausgebildet. Die Entladungsröhren, welche zu dem Hochfrequenzgenerator gehören, werden im allgemneinen mit irgendeiner Art Verkleidung versehen, um sie gegen unbeabsichtigte und gegebenenfalls gefährdende Berührung zu schützen. Die den Hochfrequenzstrom führenden Leitungen müssen durch die Wandungen einer solchen Verkleidung hindurch an den Behandlungskondensator herangeführt werden. Bisher bat man zu diesem Zwecke in die Wandung der Verkleidung besondere Durchführungen eingebaut. Die Erfindu.ngg vermeidet diese Durchführungen und verwendet zu diesem Zwecke die ohnehin zur Kopplung zwischen Behandlungskondensator und Generator häufig notwendigen Kopplungskondensatoren gleichzeitig ,als Durchführungen.According to the invention are the capacitors, "over which the Beha, udlungskondensator is coupled to the oscillating circuit of the generator, as bushings .The wall of the generator room is formed. The discharge tubes leading to the high frequency generator are generally given some type of disguise around them to protect against unintentional and possibly dangerous contact. the the high-frequency current carrying lines must go through the walls of such Cladding can be brought through to the treatment capacitor. So far asked for this purpose, special bushings are built into the wall of the cladding. The invention avoids these implementations and uses the often necessary anyway for coupling between treatment capacitor and generator Coupling capacitors at the same time, as bushings.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Von dem H.ochfrequenzgenerator sind die beiden Entladungsröhren i und 2 und die Schwingkreisinduktivität 3 gezeichnet. ¢ ist der Kondensator, in dessen Feldraum der zu behandelnde Stoff gebracht wird. In die den Generator von dem Behandlungsraum trennende Wand 5 sind die beiden Kopplungskondensatoren 6 und 7 eingebaut. Sie besitzen je eine Belegung zu beiden Seiten der Wand, die von irgendeinem zumindest zum Teil feste:ii Dielektrikum getragen werden. Dieses Dielektrikum kann beispielsweise aus Calit bestehen und, -wie aus der Zeichnung ersichtlich ist, als dünne Scheibe mit einem Wulstring ausgebildet sein. Der Wulstring dient zur Befestigung des Kondensators in der Wandung 5 und gleichzeitig als Isolation der Spannung des Hochfrequenzkreises gegen die meist geerdete Wandung. An Stelle von Calit können ,auch andere bekannte Werkstoffe als Dielektrikum dienen. Die bauliche Ausgestaltung der Kondensatoren ist nicht an das dargestellte Ausführungsbeispiel gebunden, Es müssen nur die Bedingungen erfüllt sein, die sich daraus ergeben, d;aß der Kondensator gleichzeitig die- Aufgabe einer Durchführung. d. h. :die Isolation der Nochfrequ.enzspannung ,gegen Erde, zu erfüllen hat.An exemplary embodiment of the invention is shown in the drawing. The two discharge tubes i and 2 and the are from the high frequency generator Resonant circuit inductance 3 drawn. ¢ is the capacitor in its field space the substance to be treated is brought. Into the generator from the treatment room separating wall 5, the two coupling capacitors 6 and 7 are installed. You own an occupancy on both sides of the wall, at least partially by one of them solid: ii dielectric to be worn. This dielectric can be made of, for example Calit exist and, as can be seen from the drawing, as a thin slice with be formed in a bead ring. The bead ring is used to attach the capacitor in the wall 5 and at the same time as insulation from the voltage of the high-frequency circuit against the mostly earthed wall. Instead of Calit, other well-known ones can also be used Materials serve as a dielectric. The structural design of the capacitors is not bound to the illustrated embodiment, only the conditions have to be met which result from the fact that the capacitor simultaneously performs the task an implementation. d. H. : the isolation of the frequency voltage against earth, has to meet.
