By using the dosing chamber, a first-stage reduction motor, the transmission rod, and spiral blades, the chemical solution can be prepared. The flow of the prepared chemical solution inside the dosing chamber can be controlled by activating the solenoid valve. When the chemical solution comes into contact with the industrial wastewater above the stirring blades, the chemical solution will quickly diffuse to the surrounding area, thereby improving the treatment efficiency of industrial wastewater.
[0004] However, in the aforementioned prior art, tap water is prone to contain impurities when counterweighting the medicine, which can lead to blockage of the solenoid valve with long-term use, affecting the normal discharge of the medicine and increasing maintenance costs. Utility Model Content
