Embodiment 1

[0047] This embodiment discloses a magnetic stirring device, such as figure 1As shown, it includes an upper stirring shaft assembly 26, a lower stirring shaft assembly 27 and a magnetic coupling, the upper stirring shaft assembly 26 includes an upper stirring shaft, the lower stirring shaft assembly 27 includes a lower stirring shaft 23, and the upper stirring shaft and the lower stirring shaft 23 Connection via magnetic coupling. In the magnetic stirring device in this embodiment, the stirring shaft is designed in sections by setting the upper stirring shaft assembly and the lower stirring shaft assembly, so that the long-distance power transmission of the magnetic stirring device can be realized, and it is stable and reliable, avoiding the need for an integral stirring shaft. During the stirring process, the stirring shaft is easily broken due to excessive force on the stirring shaft.

[0048] In this embodiment, the magnetic coupling adopts a cylindrical permanent magnet d...

Embodiment 2

[0061] This embodiment discloses a stirring and mixing equipment, which includes a mixing and clarifying tank 21, which is arranged in a heat chamber, and also includes the magnetic stirring device in Embodiment 1, and the upper stirring shaft assembly of the magnetic stirring device is fixedly arranged on the shielding On the cover plate 6, it is used to stir and mix the liquid in the clarification tank 21.

[0062] In this embodiment, the upper stirring shaft assembly further includes a supporting sleeve, wherein the upper end of the supporting sleeve is connected to the shielding cover plate 6 . Optionally, a shielding plug 5 is also provided between the upper end of the supporting sleeve and the shielding cover plate 6, the shielding plug 5 has an inner hole, and the inner hole wall of the shielding plug 5 is a tapered surface, which is used to connect the upper end of the supporting sleeve It is clamped in the inner hole of the shielding plug 5 to realize the axial positi...

Description

technical field [0001] The invention specifically relates to a magnetic stirring device and a stirring and mixing device comprising the magnetic stirring device. Background technique [0002] Extraction and separation is the core process of the nuclear fuel reprocessing plant. The mixing and settling tank is one of the main equipment to realize the continuous extraction and separation process of nuclear fuel reprocessing. The stirring device in the mixing and settling tank is to realize the full mixing of the two-phase material liquid key equipment. For the extraction and separation process of nuclear fuel reprocessing, such as the plutonium purification cycle, the feed liquid is highly radioactive and contains α aerosols, so higher requirements are placed on the sealing of the stirring device, and no leakage at the sealing point is allowed. The drive motor of the stirring device is installed in the maintenance hall above the shielding cover for easy maintenance. Since the ...
