[0014] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with the drawings.

[0015] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the high-shearing homogenizer with a multi-dimensional space three-dimensional shearing mechanism comprises a stator 1, a rotor 2, a safety device 3, a sealing seat 4, a mechanical seal seat 5, a main shaft 6, an outer sleeve 7, a double-end mechanical seal 8, a pressing plate 9, a pot bottom head 10, a motor 11 and the like.

[0016] The rotor includes a shaft 21, on which four blades 22 are arranged at equal intervals. The blades 22 are identical in shape and size, and preferably, the height of the upper surface of each blade 22 is higher than the height of the upper surface of the shaft 21. This allows the groove formed by the height difference between the blades 22 and the shaft 21 to accommodate the nuts and pressure plates of the positioning bolts. Preferably, the blades 22 are block-shaped, and four outwardly protrusions are evenly spaced on the outer wall of the shaft 21, with the blades 22 connected to these protrusions. The upper part of the blades 22 forms an angle of 14° to 16° with the central axis of the shaft 21, and the angle gradually increases from the upper part of the blades 22 to the lower part. The thickness of the blades 22 increases as they approach the shaft 21, thus ensuring their strength. The two upper corners of the blades 22 near the shaft 21 are sharp, thereby improving the shearing effect. The shaft 21 has a through-hole, through which the main shaft passes. Two symmetrical inward-facing strip-shaped grooves 23 are formed on the inner wall of the shaft hole. A pressure plate is provided above the shaft 21, and a positioning bolt passes through the pressure plate and connects to the main shaft. A safety element is sleeved on the outside of the positioning bolt. The safety element has a first flange extending upward, which abuts against the nut of the positioning bolt. The safety element also has a second flange extending downward, which passes through the pressure plate and extends into the strip-shaped groove 23. Thus, the safety element allows the rotor shaft to rotate in both directions with the main shaft.

[0017] The stator includes a cylindrical sidewall with an outwardly extending flange at the lower end. Bolt holes 11 are formed on the flange, allowing bolts to be used to connect the sealing seat. A discharge hole assembly 12 is formed on the sidewall, consisting of at least three rows of equally spaced discharge hole rows. The discharge holes within the same row are equally spaced, while the discharge holes in adjacent rows are staggered. A through-flow discharge groove 13, elliptical in shape, is also formed on the sidewall. The width of the discharge hole assembly is greater than the width of the rotating shaft 21 but less than the width of the blade 22 (note that all widths here refer to the orthographic projection width, i.e.,...). Figure 1 The length of the discharge hole group (as seen in the image) is greater than the height of the blade 22. The discharge channel is located below the discharge hole group, and the width of the discharge channel is greater than the width of the discharge hole group. The stator opening faces upward, and the rotor is fitted inside the stator. The upper sidewall of the discharge channel has an inwardly extending first extension, and the bottom of the rotor shaft 21 abuts against the first extension. Preferably, there are two sets of discharge holes, symmetrically opened on the sidewall. Preferably, there are two discharge channels, symmetrically opened on the sidewall. The left and right sidewalls of the discharge channel have inwardly extending second extensions. The second extensions are triangular in shape, with one triangular side connecting to the first extension and the other triangular side connecting to the sidewall. This increases the support strength of the first extension. The distance from the first extension to the central axis of the sidewall is less than the distance from the outer sidewall of the shaft 21 to the central axis of the shaft, which is greater than the diameter of the shaft hole.
