At this time, the magnetic component 120 is in the starting position; when performing overall sealing, the control device controls the first electromagnetic component 110 to be energized so that the first electromagnetic component 110 and the magnetic component 120 generate a repulsive force, pushing the magnetic component 120 to be adsorbed on the stirring shaft 300, forming a sealed state between the stirring shaft 300 and the magnetic sealing assembly, and then injecting water through the water inlet pipe 250, and the liquid level gauge 400 detects the overall height to prevent the liquid level from being too high, so as to further seal the connection position between the magnetic sealing assembly and the reactor to prevent the exchange of the environment inside the reactor and the environment outside the reactor. When loss occurs, the first water seal ring plate 210 and the third water seal ring plate 230 can be directly removed from the plug-in slot 240. Then, since the magnetic sealing assembly is detachably connected to the water seal assembly, the overall device is easy to disassemble, thereby increasing replacement efficiency.

[0045] The sealing device for a reactor of the present application has at least the following advantages:

[0046] (1) The first water seal ring plate and the third water seal ring plate can be directly removed from the plug-in slot. Since the magnetic seal assembly can be detachably connected to the water seal assembly, the entire device is easy to disassemble, thereby increasing replacement efficiency.

[0047] (2) A magnetic sealing assembly is provided, wherein the first electromagnetic member is electrically connected to a control device, which can be controlled to generate magnetism to attract or repel the magnetic member, so that the magnetic member can move back and forth along the extension direction of the slide groove to abut against or be spaced from the stirring shaft, thereby achieving sealing of the stirring shaft.

[0048] (3) A water seal assembly is provided, and the connection portion between the stirring shaft and the kettle cover is further water-sealed by the water seal assembly which is sleeved outside the magnetic seal assembly, thereby increasing the sealing effect.

[0049] (4) The utility model has reasonable design, simple structure and good practicality.
