The driving mechanism is connected to the upper end of the main shaft and is used to adjust the tilt angle of the main shaft so that the stirring disc is in an inclined or vertical state. It is also used to drive the main shaft to rotate so that the stirring disc and each stirring blade can stir the solution in the preparation chamber. During the rotation of the inclined stirring disc, it will intermittently abut against the lower end of the push rod and intermittently push the push rod upward so that the outer edge of the sealing member separates from the side wall of the feeding channel.

6. The wastewater treatment flocculant solution preparation apparatus according to claim 5, characterized in that, There are multiple mixing discs, each arranged from top to bottom, and the diameter of each mixing disc increases sequentially from top to bottom. The lowest mixing disc is used to abut against the lower end of the push rod.

7. The wastewater treatment flocculant solution preparation apparatus according to claim 6, characterized in that, There are multiple feeding channels and sealing mechanisms. The feeding channels form a ring structure. During the rotation of the lowest inclined stirring plate, it will intermittently and alternately abut against the lower end of each push rod, and intermittently push each push rod to move upward alternately, so that the outer edge of each sealing member will alternately separate from the side wall of the feeding channel.

8. The apparatus for preparing flocculant solution for wastewater treatment according to claim 5, characterized in that, The driving mechanism includes a rotating frame, a first driving component, and a second driving component. The rotating frame is disposed inside the preparation cavity. The first driving component is disposed on the rotating frame and connected to the upper end of the main shaft, and is used to drive the main shaft to reciprocate to adjust the tilt angle of the main shaft and to keep the stirring plate in an inclined or vertical state. The second driving component is connected to the rotating frame and is used to drive the rotating frame to rotate.

9. The apparatus for preparing flocculant solution for wastewater treatment according to claim 8, characterized in that, The first driving assembly includes a movable seat, a sliding shaft, and a telescopic drive component.
