Abstract

The invention provides a plasma generator. The plasma generator comprises an anode, a cathode mechanism and a rotating mechanism, wherein the first end of the anode is provided with an electric arc outlet; the cathode mechanism is eccentrically suspended in the anode, and a gap between the cathode mechanism and the anode forms an airflow channel; the cathode mechanism comprises at least two cathode heads, and the rotating mechanism is used for enabling the cathode mechanism to rotate, so that any cathode head corresponds to the electric arc outlet. According to the plasma generator, the cathode mechanism is eccentrically suspended in the anode, after the cathode head is used, only the rest cathode heads need to be rotated to correspond to the electric arc outlet through the rotating mechanism, and the cathode head is replaced without shutdown, so that the plasma generator can stably and continuously work, and the service life of the plasma generator is prolonged; and the risk of replacing the cathode head by halting is reduced, and the economic loss is reduced.

Description

technical field [0001] The present invention relates to the field of plasma technology, in particular to a plasma generator. Background technique [0002] The arc plasma generator is a discharge device capable of generating directional "low temperature" (2000-20000K) plasma jets. The arc plasma generator is mainly composed of a cathode (the anode is replaced by a workpiece) or cathode and anode poles, and a discharge chamber And the plasma working gas supply system consists of three parts. [0003] At present, most of the plasma generators have a structure in which the cathode is arranged in the anode. This type of plasma generator can operate normally and stably for a short period of time, requiring frequent manual replacement of components. Usually, the methods to improve the life of the plasma generator are mainly to improve the cooling efficiency of the electrode, use a noble metal alloy with a slower erosion rate for the electrode, and magnetic field confinement, etc.,...
