[0025] Specifically, if Figure 1 and Figure 3 As shown, when in use, when the motor 4 is started, the rotating shaft 5 can be driven to rotate, and the multiple sets of main stirring rods 6 on the outer wall of the rotating shaft 5 stir the middle and upper position inside the reaction tank 1, and the auxiliary stirring rods 15 outside the bottom side adjustment tube 9 stir the lower position inside the reaction tank 1. If the electric push rod 11 inside the adjustment tube 9 is started to extend and retract, the lifting rod 12 can be driven to move up and down. In this way, the auxiliary stirring rod 15 can be driven to move up and down with the assistance of the slider 14 to adjust the stirring position of the auxiliary stirring rod 15;

[0026] An auxiliary mixing assembly is provided at the top of the interior of the reaction tank 1, and the auxiliary mixing assembly includes a positioning platform 16, a pretreatment tube 17, an auxiliary feeding tube 18, a positioning ring 19, a dispersion blade 20 and an auxiliary discharge tube 21.
