Embodiment 1
[0038] like Figure 5 As shown, this embodiment includes: electrode rod 1, positioning screw 2, bushing 3, positioning guide sleeve 4, annular permanent magnet 5, electrode cap 6, plate 7 and electrode dresser 8, wherein: bushing 3 and electrode The rod 1 is fixedly connected by a positioning screw, the positioning guide sleeve 4 is movably socketed with the bushing 3, the annular permanent magnet 5 is fixedly connected with the positioning guide sleeve 4, and the electrode cap 6 is connected with the electrode rod 1.
[0039] The magnetization direction of the annular permanent magnet 5 is parallel to its axis of symmetry, and its magnetic field distribution is axisymmetric.
[0040] The number of the ring-shaped permanent magnets 5 is 1 pair, and the polarities are mutually exclusive, so as to realize double-sided stirring.
[0041] The annular permanent magnet 5 has an inner diameter 0.5mm larger than the outer diameter of the electrode rod, a wall thickness of 5mm, and a ...
