[0023] An annular liquid storage chamber 170 is provided inside the fixed disk 140, and a liquid outlet 160 is provided on the inner circle of the fixed disk 140. The liquid outlet 160 is communicated with the annular liquid storage chamber 170, and a liquid outlet mechanism 180 is installed inside the liquid outlet 160. A first cylinder 141 for connecting with the support plate 120 is symmetrically installed on the upper side of the fixed disk 140, a movable disk 190 is installed on the bottom side of the support plate 120, and a second cylinder 210 for lowering the movable disk 190 is installed between the movable disk 190 and the support plate 120. A blade 220 for demagnetizing the steel sheet of the solid rotor 240 is arranged on the bottom side of the movable disk 190. Acetone liquid is placed inside the annular liquid storage chamber 170. Acetone liquid is a common sol liquid, so it is not explained in this embodiment.

[0024] There are four support columns 130, which are installed in a rectangular array between the operating table 110 and the support plate 120. A fixing column 131 for connecting the operating table 110 is installed on the bottom side of the operating table 110. There are two fixing columns 131, which are installed in a rectangular array on the bottom side of the operating table 110.

[0025] A liquid inlet 171 is provided on the upper side of the fixed disk 140 . The liquid inlet 171 is communicated with the annular liquid storage chamber 170 . A sealing cover 172 is installed on the upper side of the liquid inlet 171 to seal the liquid inlet 171 .

[0026] The liquid outlet mechanism 180 includes an annular block 181, a pushing spring 182, a pushing rod 183, a sealing block 184 and a pushing block 185. The annular block 181 is installed on the inner circle of the liquid outlet 160, and the pushing block 185 is arranged adjacent to the side of the annular block 181. The pushing block 185 is movably matched with the liquid outlet 160. The sealing block 184 is arranged as a rubber block, and the sealing block 184 is arranged on the other side of the pushing block 185.

[0027] The push rod 183 and the annular block 181 are interlaced and movable, the sealing block 184 and the push block 185 are both arranged at the two ends of the push rod 183, the sealing block 184 and the liquid outlet 160 are slidingly interlocked, the push spring 182 is installed between the push block 185 and the annular block 181, the push block 185 and the liquid outlet 160 are clearance-matched, and the push rod 183 and the annular block 181 are clearance-matched. The blade 220 is pushed by the second cylinder 210, the blade 220 contacts the push block 185, and the blade 220 resists the push block 185.

[0028] In this embodiment, when in use, the solid rotor is placed between the fixed disk 140 and the engaging disk 150, and the movable disk 190 is pushed by the second cylinder 210, so that the movable disk 190 drives the blade 220 to move downward. When the blade 220 moves downward, the side of the blade 220 contacts the pushing block 185, so that the blade 220 pushes against the pushing block 185 to the inside of the liquid outlet 160. When the pushing block 185 moves to the inside of the liquid outlet 160, the pushing block 185 squeezes the pushing spring 182, and the pushing spring 182 is in a compressed state. Since the sealing block 184 is connected to the pushing block 185 through the pushing rod 183, when the pushing block 185 moves, the sealing block 184 moves toward the inside of the annular liquid storage chamber 170, so that a gap is generated between the sealing block 184 and the liquid outlet 160, so that the liquid flows out of the liquid outlet 160. Since the blade 220 and the fixed disk 140 are movable and fit, the liquid flows to the surface of the blade 220, and then drips to the outside of the solid rotor, dissolving the solidified glue between the solid rotor and the magnetic steel sheet. At the same time, the falling of the blade 220 contacts the magnetic steel sheet, so that the magnetic steel sheet is separated from the solid rotor.

[0029] Embodiment 2: This embodiment is intended to facilitate solving the problem of sealing and opening the liquid outlet. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 - Figure 4 There are a plurality of liquid outlets 160 , which are arranged in an annular array on the inner circle of the fixed disk 140 . The blade 220 is arranged as an annular blade 220 , and the blade 220 is slidably fitted with the outer wall of the solid rotor 240 .

[0030] In this embodiment: when in use, by installing a push spring 182 between the annular block 181 and the push block 185, when the blade 220 moves upward, the blade 220 loses contact with the fixed disk 140, so that the push spring 182 is compressed and expanded to push the push block 185, and the push block 185 is pushed by the push spring 182, and the push block 185 moves to the outside of the liquid outlet 160, so that the sealing block 184 is connected to the push block 185, so that the sealing block 184 returns to the inside of the liquid outlet 160 to seal. This solution has a simple structure and is easy to operate. A push spring 182 is installed between the annular block 181 and the push block 185, so that the liquid outlet 160 can be sealed and opened.
