Mixer suitable for seawater pretreatment

The invention relates to the technical field of mixers, in particular to a mixer suitable for seawater pretreatment, which comprises a treatment component, a water inlet component, a water outlet component and a water outlet component, the uniform mixing assembly comprises a movable pipe arranged below the medicine adding pipe, a connecting pipe arranged below the movable pipe, a plurality of liquid guide pipes arranged on the outer wall of the connecting pipe and liquid guide channels formed in the liquid guide pipes; the driving assembly arranged in the chemical adding pipe is provided with a plurality of liquid guide channels, so that the situation that chemicals enter the mixer in a concentrated mode to cause local saturation is avoided, the liquid guide pipes rotate through the driving assembly, and therefore the chemicals can be diffused and can fully react and make contact with raw water under stirring of the liquid guide pipes, the reaction time is shortened, and the chemical adding efficiency is impr
