Homogeneous mixing apparatus

A homogenous mixing apparatus with a material feeding direction, comprising:

• a circulation unit, comprising a storage space capable of storing materials, a feeding end capable of feeding materials, and a discharging end capable of outputting materials;
• a dynamic mixing unit, sequentially comprising, in the feeding direction, a first-stage dynamic mixing device, a second-stage dynamic mixing device and a third-stage dynamic mixing device which are connected in series in a material circulating manner, and respectively correspond to mixing and dissolving, dispersion and emulsification of materials, wherein a feeding port of the first-stage dynamic mixing device communicates with the discharging end of the circulation unit, a discharging port of the third-stage dynamic mixing device communicates with the feeding end of the circulation unit, an upstream side of the first-stage dynamic mixing device is further provided with a first feeding device capable of feeding a material to the first-stage dynamic mixing device, an upstream side of the second-stage dynamic mixing device is further provided with a gas conveying device capable of conveying a gas to the second-stage dynamic mixing device, an upstream side of the third-stage dynamic mixing device is further provided with a second feeding device capable of feeding a material to the third-stage dynamic mixing device, and each of the dynamic mixing devices comprises a dynamic mixer;
• and
• a control unit, configured to be capable of controlling the dynamic mixing unit, so that the dynamic mixers of the first-stage dynamic mixing device, the second-stage dynamic mixing device, and the third-stage dynamic mixing device are capable of being independently started and shut down and operated at independent rotating speeds, wherein
• the dynamic mixers each comprise a stator and a rotor, rotating speed ranges of the dynamic mixers of the first-stage dynamic mixing device, the second-stage dynamic mixing device, and the third-stage dynamic mixing device increase in sequence, and distances between the rotors and the stators decrease in sequence.
