[0002] Neutralization tank is a kind of equipment used to treat industrial wastewater. Its main purpose is to adjust acidic and alkaline wastewater to neutrality to meet the discharge standards. The working principle of the neutralization tank is to mix acidic or alkaline wastewater with another chemical (usually lime or sulfuric acid) to make the two react chemically to produce salt and water. This process can effectively reduce the acidity or alkalinity in the wastewater to meet the discharge standards.

[0003] Although the traditional neutralization tank is widely used, it still has some shortcomings. For example, during the neutralization process of the material, the material will adhere to the inner wall of the neutralization tank, and precipitation will be generated during the reaction. If it is not cleaned, it will scale on the inner wall of the neutralization tank for a long time, thereby affecting the subsequent neutralization effect. The stirring blades of the existing neutralization tank are usually welded to the stirring shaft, and different stirring blades cannot be replaced according to different materials to ensure the stirring effect. Therefore, a kind of anti-scaling mechanism of the neutralization tank is proposed to address the above problems. Utility Model Content
