Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage arc plasma generating devices, in particular to an anti-loosening electrode. Background Art

[0002] The high-voltage arc plasma generator uses the tip discharge of three-phase AC high voltage electricity to ionize and ignite the air. During the working process, the electrode has the greatest impact on the working state. For example, if the spacing between the three electrodes is unequal, two of the electrodes will discharge more times, causing excessive wear of the two electrodes and further worsening the situation. In the actual use of the high-voltage arc plasma generator, the equipment also needs to be connected to an external working gas supply device, a material supply device to be processed, etc. Therefore, in the entire work process, the electrodes of the high-voltage arc plasma generator will be affected by the vibration of various equipment, resulting in loosening, falling out, etc.

[0003] The electrode of a high-voltage arc plasma generating device includes an upper electrode and a lower electrode. The upper electrode serves as a fixed part and the lower electrode serves as a cantilever part. The traditional method is to open a threaded groove on the upper electrode and set a threaded column on the lower electrode to connect the upper electrode and the lower electrode. However, the traditional method of setting the threaded column on the lower electrode will cause the threaded column to be much thinner than the upper electrode, and the bearing capacity is poor. When the equipment is working, the high vibration environment it generates can easily cause the electrode connection part to bend and deform. In addition, the existing anti-loosening gasket is directly mounted on the threaded column on the lower electrode. In this way, after the electrode is installed, the anti-loosening gasket is exposed to the outside, and the anti-loosening gasket will be quickly damaged by the high-voltage arc during use, so it needs to be improved. Utility Model Content
