After the alkali preparation is completed once, the alkali preparation stirring barrel is cleaned, and the influence of residual liquid in the alkali preparation stirring barrel on the next alkali preparation is avoided.

Further, a stirring motor is arranged on the alkali-blending stirring barrel, and the stirring motor is a variable frequency motor. Can change motor stirring speed according to the concentration of ratio, slowly stir when solution volume is few, the stirring with higher speed when solution volume is many, the energy can be saved, the lifting efficiency.

The utility model has the advantages that:

1. the utility model discloses in through the opening and shutting of weighing sensor control solenoid, realized realizing accurate ratio, reduce manual operation, the security promotes by a wide margin.

2. The utility model discloses when well alkali bucket and the pure water bucket of weighing reached predetermined weight, weighing sensor transmitted signal gave the solenoid valve, closed No. three pipelines and No. four pipelines, avoided the interior liquid of alkali bucket and the pure water bucket of weighing to spill over.
