Abstract
The invention discloses multi-ring arc plasma electrodes, which are applied to arc plasma ignition, arc plasma cutting and arc plasma spraying. One kind of the electrodes comprises a copper ring sleeve, a plurality of copper silver alloy rings are overlapped in the copper ring sleeve, and at least one silver ring and one emission ring are arranged between a plurality of copper silver alloy rings; and the other kind of the electrodes comprises a copper ring seat, one inner blind hole and one outer blind hole are at least formed in the copper ring seat, an inner silver ring is arranged in the inner blind hole, and an outer emission ring is arranged in the outer blind hole. The multi-ring arc plasma electrodes have the advantages of simple structure, long service life, high reliability, high stability, safety and environment friendliness.
Description
Technical field
The present invention relates to arc plasma electrode, especially a kind of polycyclic arc plasma electrode that is applicable to arc plasma igniting, arc plasma cutting and arc plasma spraying.
Background technology
Arc plasma is widely used in the fields such as the arc plasma igniting, arc plasma cutting processing, arc plasma spraying of pulverized-coal fired boiler now, but the ablation of the electrode material of arc plasma is restricting the application of arc plasma always.While being applied in ignition of the boiler field as arc plasma, require arc plasma electrode life to reach thousands of hours, but not yet have in the world the generally acknowledged arc plasma electrode material that reaches this order of magnitude at present.Arc plasma cutting and arc plasma spraying are due to not long-term continuous operation, and the impact of electrode life is not to give prominence to very much, conventionally in 5-8 hour, changes an electrode, but has caused serious waste and environmental pollution.Therefore develop cheap New Arc plasma electrode material and electrode structure extremely important.
Summary of the invention
The object of the invention is to overcome the weak point in prior art, provide a kind of simple in structure, cut the waste and the polycyclic arc plasma electrode of environmental pollution.
A polycyclic arc plasma electrode of the present invention, comprises copper ring cover, and in copper ring cover, closed assembly has multiple Kufil rings, is at least provided with a silver ring and a transmitting ring between multiple Kufil rings.
Another kind of polycyclic arc plasma electrode, comprises copper ring seat, at least has an inside and outside annular blind hole in copper ring seat, is provided with interior silver ring in interior annular blind hole, is provided with outer transmitting ring in outer ring blind hole.
Described transmitting ring and the surface of outer transmitting ring are coated with silver, copper or gold;
Described transmitting ring and outer transmitting ring are that one or more materials in thorium, hafnium, titanium, tungsten, graphite are made.
Beneficial effect: owing to having adopted technique scheme, compared with prior art, tool has the following advantages:
1. improve compared with having had the useful life of the electrode of homogenous material significantly the useful life of polycyclic plasma electrode;
2. the electric arc striking reliability of polycyclic plasma electrode is high;
3. the arc stability of polycyclic plasma electrode is higher;
Electrode life higher, use safer.
