A connecting block 3-3 is arranged at the bottom of the stirring shaft 3-2, and arc-shaped stirring blades 3-4 are arranged on the opposite sides of the connecting block 3-3. A connecting frame 3-5 is arranged on the inner top of the reactor tank 1, and the connecting frame 3-5 is mounted on the stirring shaft 3-2.
[0031] In this embodiment, the output unit 3-1 serves as the main driving force to drive the stirring shaft 3-2 to rotate. In an ideal state, the stirring shaft 3-2 is in a vertical state and will not tilt. After the stirring shaft 3-2 drives the connecting block 3-3 to rotate, stirring is performed through the arc-shaped stirring blade 3-4, and the connecting frame 3-5 is used to limit the stirring shaft 3-2.
[0032] Specifically, the inner wall of the connecting frame 3-5 is provided with a limit bearing 3-6, the limit bearing 3-6 is mounted on the stirring shaft 3-2, the outer wall of the limit bearing 3-6 is fixedly connected to the connecting frame 3-5, and the inner wall of the connecting frame 3-5 is provided with a touch sensor 3-7.
[0033] In this embodiment, the limit bearing 3-6 limits the stirring shaft 3-2 inside the connecting frame 3-5 to prevent the stirring shaft 3-2 from being tilted. If the stirring shaft 3-2 is tilted at a large angle, the stirring shaft 3-2 will touch the touch sensor 3-7, thereby detecting that the stirring shaft 3-2 has been seriously tilted and performing timely maintenance.

The output unit 3-1 serves as the main power to drive the stirring shaft 3-2 to rotate. In an ideal state, the stirring shaft 3-2 is in a vertical state and will not tilt.
