Multiple sets of neatly arranged stirring blades 22 are fixedly connected to the outer wall of the rotating shaft 21. The surface of each stirring blade 22 has slotted holes 23. Four sets of stirring blades 21 are arranged in an array around the center of the mixing tank 1. Gears 24 are fixedly connected to the outer surface of the rotating shaft 21. The rotating shaft 21 drives the stirring blades 22 to rotate, achieving mixing of the reagent liquid through the multiple stirring blades 22. The slotted holes 23 on the stirring blades 22... 3. To increase liquid fluidity and mixing effect during the mixing process, four sets of brackets 25 are fixedly connected to the inner wall of the mixing tank 1. Gear rings 26 are rotatably connected between the four sets of brackets 25, and each gear ring 26 meshes with one of the four sets of gears 24. The side walls and bottoms of the four sets of brackets 25 and gear rings 26 are in contact with each other, providing support and positioning for the gear rings 26. Through the transmission action between the gear rings 26 and the gears 24, the four sets of gears 24 and the rotating shaft 21 drive all the stirring blades 22 to rotate synchronously, thereby improving the uniformity and speed of mixing. A motor 27 is fixedly connected to the surface of the mixing tank 1. The output shaft of the motor 27 passes through and is rotatably connected to the inner wall of the mixing tank 1. The output shaft of the motor 27 is fixedly connected to the end of the rotating shaft 21.
