[0002] Polyacrylamide is a linear organic high molecular polymer and also a high molecular water treatment flocculant product. It can be used to treat domestic sewage and organic wastewater.

[0004] However, when the above technical solution is used, the stirring rod is driven by the primary output shaft to quickly dissolve and mix the polyacrylamide and water, which easily leads to different solution concentrations in each layer in the hydrolysis tank, and polyacrylamide particles will precipitate in the hydrolysis tank, affecting the hydrolysis effect of the polyacrylamide; and the mixed liquid is easy to adhere to the inner wall of the mixing tank, and too much residual liquid causes waste.

[0005] To this end, we proposed a polyacrylamide solution mixing device. Utility Model Content
