[0026] The specific embodiments of the present utility model are described below with reference to the accompanying drawings.

[0027] like Figure 1-5 An emulsifying homogenizing head is shown, comprising a stator 1 and a rotor 2, wherein both the stator 1 and the rotor 2 are provided with a through flow channel, the rotor 2 comprises an outer ring portion 3 and a blade body 4 connected to the outer ring portion 3, the end face of the blade body 4 on one side of which is rotatably matched with the stator 1 is lower than the outer end face of the outer ring portion 3, the side wall of the outer ring portion 3 is provided with a plurality of first discharge channels 5 along the circumferential direction, the stator 1 comprises an outer cylinder portion 6 and an inner ring portion 7, a drop is formed between the outer cylinder portion 6 and the inner ring portion 7, and the inner ring portion 7 is lower than the outer cylinder portion 6, a rotary groove 8 for inserting the outer ring portion 3 is formed between the outer cylinder portion 6 and the inner ring portion 7, the blade body 4 is matched with the inner ring portion 7, and the outer cylinder portion 6 and the inner ring portion 7 are respectively provided with a plurality of second discharge channels 9 and a third discharge channel 10 along the circumferential direction.

[0028] The outer ring portion 3 of the rotor 2 is confined in the rotary groove 8, and the two side walls of the rotor 2 cooperate with the inner wall of the outer cylinder portion 6 and the outer wall of the inner ring portion 7 to form multi-stage shearing. The high-speed operation of the rotor 2 and the stator 1 generates a strong suction force, and the material is sucked into the cavity formed between the rotor 2 and the stator 1. The material is thrown into the narrow and tight gap between the stator and rotor 2 from the radial direction, and is subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tearing and turbulence. As a result, the immiscible solid phase, liquid phase and gas phase are sheared more delicately under the joint action of corresponding mature processes and appropriate additives.

[0029] The width of the revolving groove 8 gradually decreases from bottom to top, the cross section of the outer ring portion 3 is trapezoidal, and the two side walls of the revolving groove 8 are adapted to the shapes of the inner and outer sides of the outer ring portion 3.

[0030] The inner and outer side surfaces of the outer ring portion 3 are conical surfaces. Similarly, the inner wall of the outer cylinder portion 6 and the outer wall of the inner ring portion 7 are conical surfaces. Pads can be placed in the rotary groove 8 in advance to change the longitudinal position of the outer ring portion 3 of the rotor 2, and then adjust the size of the gap between the two sides of the outer ring portion 3 and the outer cylinder portion 6 and the inner ring portion 7 to achieve shearing of particles of different sizes.

The fan blade body 4 includes a connecting part 13 and a plurality of blades 14 arranged around the connecting part 13. The avoidance opening 11 is arranged between the outer end of the blade 14 and the outer ring part 3, so that the fan blade body 4 can be inserted into the inner side of the inner ring part 7.

[0032] The end face of the fan blade body 4 away from the stator 1 gradually tilts from the outer edge toward the center to form a fan blade surface 12 that is higher in the middle and lower on the outside.
