The lifting plate 23 includes an arc plate 231 and a spiral plate 232, and the arc plate 231 and the spiral plate 232 have a smooth transition. The screw rod 24 can be provided to adjust the height of the lifting plate 23 so that it can be used to mix materials at different liquid levels;

[0023] The internal circulation mechanism includes a liquid outlet pipe 31 connected to the bottom end of the stirring tank 1, a liquid inlet pipe 32 connected to the top position of the stirring tank 1, and a circulation pump 33 fixed next to the stirring tank 1. The liquid inlet end of the circulation pump 33 is connected to the liquid outlet pipe 31, and the liquid outlet end of the circulation pump 33 is connected to the liquid inlet pipe 32. The circulation pump 33 is a peristaltic pump. The peristaltic pump can make the medicine circulate only in the pipeline without contacting the outside world.

[0024] Reference Figure 2 A blocking plate 4 is also provided in the mixing tank 1. A guide groove 5 is vertically fixed on the top inner wall of the mixing tank 1. The blocking plate 4 is slidably connected in the guide groove 5. An electric push rod 6 is also vertically fixed on the mixing tank 1. The piston rod end of the electric push rod 6 is fixed to the blocking plate 4. One side of the blocking plate 4 is arranged to fit the inner wall of the mixing tank 1. Specifically, in order to enhance the strength of the blocking plate 4, the main cross-section of the blocking plate 4 is a triangle.

[0025] By providing a blocking plate 4, after stirring and mixing for a period of time, the electric push rod 6 pushes the blocking plate 4 to move to the bottom of the stirring tank 1, thereby blocking the liquid centrifugally rotating around the inner wall of the stirring tank 1, hindering the stirring of the raw materials, and effectively improving the mixing efficiency of the raw materials.

[0026] The implementation principle of a mixing device for flocculant production and preparation in the embodiment of the present application is as follows:

[0027] The raw materials are stirred by the stirring paddle and centrifugally mixed around the inner wall of the stirring tank 1. When the speed of the stirring shaft 12 is increased, the raw materials near the top are blocked by the lifting plate 23, and the raw materials enter the spiral plate 232 through the arc plate 231, and are thrown into the middle of the stirring tank 1 by one end of the spiral plate 232, which can accelerate the mixing of the raw materials. In this process, the circulation pump 33 works to pump the raw materials at the bottom of the stirring tank 1 to the top of the stirring tank 1 and throw them down, which can once again improve the mixing effect and make the upper and lower reagents in the stirring tank 1 evenly mixed.

[0028] Finally, the blocking plate 4 is lowered several times by the electric push rod 6 to block the centrifugal rotating liquid and hinder the stirring of the raw materials, which can effectively improve the mixing efficiency of the raw materials, make the raw materials mixed more evenly, react more thoroughly, and ensure the quality of the medicine.
