Background

The device integrates the functions of coagulation, sedimentation and filtration into a whole, and is widely used in water purification projects. The coagulation refers to a process of aggregating colloidal particles and tiny suspended matters in water by adding chemical agents, and in specific implementation, raw water added with coagulant is injected into a coagulation unit, and then vortex reaction is adopted to enable the suspended matters in water and the coagulant to fully contact and react, so that alum flowers are formed, and relatively clean water can be obtained after the alum flowers settle. At present, most of the way of generating vortex of raw water is realized by adopting a combined structure of a motor and a stirring shaft, for example, just like a flocculation device disclosed in Chinese patent document with publication number of CN211310979U, water and flocculant are fully mixed by stirring action of the stirring shaft. In this method, the rotational speed of the stirring shaft is relatively stable, and if the rotational speed is too high, stability of the form of alum blossom is not favored, and in particular, stability of the form of large-volume alum blossom is not favored, that is, alum blossom is likely to be scattered due to too high vortex flow rate after formation, and if the rotational speed is too low, contact between the suspended matter and the coagulant is insufficient, and it is difficult to form enough alum blossom. Therefore, the effect of using the flocculation device by combining the motor and the stirring shaft is not satisfactory, and the flocculation device needs to be improved.
