摘要:
A plasma torch is formed from a hollow electrode forming a first gap to an isolated plasma tube, the isolated plasma tube forming a second gap with a plasma outlet tube having electrically common plasma tubes which terminate into a plasma outlet. The first gap and second gap of the isolated plasma tubes are fed by a source of plasma gas such that when a voltage is applied across the electrodes, plasmas initially form across the first plasma gap and second plasma gap. The formed plasmas spread laterally until the plasmas are formed entirely from electrode to electrode and self-sustaining. Plasma gasses which are fed to the plasma torch can be metered on both sides of the electrodes to steer the plasma arc attachment axially over the extent of the hollow electrodes, thereby reducing surface wear and increasing electrode life.
摘要:
Die Erfindung betrifft eine Vorrichtung (1) zum Behandeln von Kleinteilen mittels eines Plasmas, die insbesondere eine Plasmaeinrichtung (3) umfasst, mit der ein Plasma erzeugbar ist, das sich zumindest über einen Bereich des Innenraums (6) des Gehäuses (2) erstreckt und zumindest zeitweise auf die sich in oder an dem Träger (17) befindlichen oder sich mit diesen bewegenden Kleinteilen einwirkt, wobei sich das Plasma zwischen zwei voneinander beabstandeten Elektroden (23) erstreckt, und das Plasma zwischen zwei stillstehenden Elektroden (23) erzeugbar ist. Um die Vorrichtung dahingehend weiterzuentwickeln, dass eine Aufheizung der mechanischen Bestandteile und somit ein Verschleiß gering gehalten wird, wird vorgeschlagen, dass die Plasmaeinrichtung (3) sich in einem Nebenraum (13) befindet, der außerhalb eines Einwirkungsbereichs angeordnet ist, der von der Dreheinrichtung (18) und dem Träger(17) und den zu behandelnden Kleinteilen überstrichen wird und einen Teil des Innenraums (6) bildet. Weiterhin betrifft die Erfindung ein Verfahren zum Behandeln von Kleinteilen in einem Plasma.
