[0002] The existing stirring vacuum drying machine is easy to stick material, corrode and precipitate metal ions in the internal contact part with the material, and electrolytic polishing is needed to ensure the smoothness.
[0003] Electrolytic polishing is to immerse the workpiece as anode and insoluble metal as cathode into the electrolytic tank, and the metal ions falling off from the workpiece form an oxidation film adsorbed on the surface of the workpiece with the acid in the electrolyte. The surface micro convex part is thin, the current density is large, and the metal dissolution is fast; the surface micro concave part is thick, the current density is small, and the metal dissolution is slow. With the flow of the film, the concave and convex parts change continuously, and the rough surface is gradually polished flat.
[0004] However, the conventional electrolytic polishing has shape limitation requirements for the polished workpiece; the current is too large in the electrolytic polishing process of the corner and tip parts of the workpiece, which can cause over-corrosion. The concave part of the workpiece is easily shielded by the workpiece itself or the hanger in the polishing process, resulting in silver-white spots on the polished surface.
[0005] Therefore, the structure of the existing mixing device, especially the assembly positioning part, cannot meet the high-precision electrolytic polishing requirements. The position of the sealing part mounted on the upper part of the vacuum cover is kept in high-precision fit by the positioning bolt, but the positioning bolt is exposed to contact with the material, and the existing electrolytic polishing technology cannot perform high-precision electrolytic polishing on the bolt.
[0006] Therefore, it is necessary to develop a mixing device with internal performance protection. CONTENT OF THE UTILITY MODEL

[0010] As a further improvement of the above technical solution:
[0011] Preferably, the structure of the sealing structure mounting seat is an oil seal seat closely combined with the upper flange surface of the kettle cover upper flange, and an oil seal is arranged in the oil seal seat.
[0012] Preferably, the oil seal seat and the kettle cover upper flange are locked by a fastening bolt.
[0013] Preferably, an O-shaped sealing ring is additionally arranged on the outer circular surface of the oil seal seat.
[0014] Preferably, the fastening bolt sequentially penetrates the inner holes of the oil seal seat and the kettle cover upper flange from top to bottom, and locks and closely combines the oil seal seat and the kettle cover upper flange.
[0015] Preferably, the top surface of the kettle cover is in a circular arc shape, and the kettle cover upper flange is located at the middle position of the circular arc top surface of the kettle cover.
[0016] Preferably, the mass accuracy of the first electrolytic polishing layer and the second electrolytic polishing layer is 0.25 μm.
