[0028] The following description is for the purpose of illustrating the preferred embodiments of the present invention. However, the above description is for the purpose of illustrating the general principles of the present invention and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined by the appended claims.

[0029] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of a pulping apparatus 1000 provided in an embodiment of the present invention. The pulping apparatus 1000 includes a pulping tank 100 and a dispersion mechanism 300. The dispersion mechanism 300 is disposed within the pulping tank 100 and is used to disperse the slurry. Of course, in some embodiments, the pulping apparatus 1000 may omit the pulping tank 100. That is, the pulping apparatus 1000 does not include the pulping tank 100, and the inner cavity of the dispersion mechanism 300 is used to accommodate and disperse the slurry.

[0030] Illustratively, in this embodiment, the slurry can be a battery slurry. Battery slurry is a solid-liquid mixture. Battery slurry includes a variety of materials, such as but not limited to solvents, conductive agents, liquids or powders, etc., and various materials are mixed to form battery slurry. Powders include but are not limited to active substances, conductive agent powders, adhesive powders and other powder materials. Liquids include but are not limited to liquids such as conductive agent solutions and adhesive solutions. Liquids can also include liquids obtained by mixing powders and liquids. In this embodiment, the slurry is illustrated as a battery slurry. It can be understood that the dispersion mechanism 300 can also be used to disperse other slurries, such as food, medicine, fertilizers, building materials, etc., and the application of the dispersion mechanism 300 is not limited here.

[0031] It should be noted that Figure 1 The purpose is only to schematically describe the arrangement between the pulping tank 100 and the dispersion mechanism 300, and is not to specifically limit the connection position, connection relationship and specific structure of each component. Figure 1 The structure of the pulping device 1000 is only shown in the embodiment of the present invention, and does not constitute a specific limitation on the dispersion mechanism 300. In other embodiments of the present invention, the pulping device 1000 may include Figure 1 More or fewer components, or combinations of certain components, or different components are shown, for example, the pulping device 1000 may further include but is not limited to a driver, etc. The driver is used to drive the dispersion mechanism 300 to disperse the slurry.

[0032] In this embodiment, the pulping tank 100 includes a tank body 110 and a tank cover 120 connected to the tank body 110. The tank cover 120 and the tank body 110 form a receiving chamber 101 for accommodating the dispersion mechanism 300. The tank cover 120 and the tank body 110 are detachably connected, thereby facilitating the assembly, maintenance, tilting, and other operations of the various components of the pulping equipment 1000. Specifically, the dispersion mechanism 300 is arranged at the bottom of the tank body 110 facing away from the tank cover 120. As a result, the assembly of the stirring mechanism and the dispersion mechanism 300 is facilitated, the layout is reasonable, the structure is compact, and the cleaning and maintenance of the components of the pulping equipment 1000 are convenient. Of course, in some embodiments, the dispersion mechanism 300 can also be arranged in the middle of the pulping tank 100. The setting position of the dispersion mechanism 300 can be set according to actual conditions, and the embodiment of the utility model does not make specific restrictions.

[0033] It is understandable that when pulping is performed using the pulping apparatus 1000, liquid material can be added to the pulping tank 100 first, and the liquid material can be pre-dispersed by the dispersion mechanism 300 before the powder material is added, thereby improving the wetting effect of the liquid material on the powder material and improving the dispersion and mixing effect of the dispersion mechanism 300; alternatively, liquid material can be added to the pulping tank 100 first, and then the powder material, and after the powder and liquid material are added, the dispersion mechanism 300 is started to disperse, so as to achieve a cyclic reciprocating motion of the pulp in the pulping tank 100. The pulping tank 100 is provided with a discharge pipe 103 to enable the discharge of the slurry. Optionally, the discharge pipe 103 is provided at the bottom of the pulping tank 100. The discharge pipe 103 is arranged to be tilted downward relative to the central axis P of the pulping tank 100, thereby improving the discharge effect.

[0034] Please also refer to Figure 1 and Figure 2 , Figure 2 yes Figure 1 1 is a cross-sectional view of a first embodiment of a dispersion mechanism 300 of a pulping apparatus 1000 in FIG. The dispersion mechanism 300 includes a stator 10 and a rotor 30. The stator 10 includes a stator base 11 and a stator ring 13 disposed on the stator base 11. The stator ring 13 is provided with a plurality of stator slots 1301 along the circumferential direction Z of the dispersion mechanism 300. The rotor 30 includes a rotor base 31 and a rotor ring 33 disposed on the rotor base 31. The rotor ring 33 and the stator ring 13 are alternately arranged along the radial direction Y of the dispersion mechanism 300 and are rotatably engaged. The rotor ring 33 is provided with a plurality of rotor slots 3301 along the circumferential direction Z of the dispersion mechanism 300. In the radial direction Y of the dispersion mechanism 300, the stator slots 1301 are connected to the rotor slots 3301 to form a shear flow channel 40. The shear flow channel 40 includes a first flow channel section 41 and a second flow channel section 42. The first flow channel section 41 and the second flow channel section 42 are arranged along the flow direction of the slurry. The cross-sectional area of ​​the first flow channel section 41 perpendicular to the flow direction gradually decreases along the flow direction, while the cross-sectional area of ​​the second flow channel section 42 perpendicular to the flow direction gradually increases along the flow direction.

[0035] The dispersion mechanism 300 provided in the embodiment of the present invention is based on the arrangement of the first flow channel section 41 and the second flow channel section 42 along the flow direction of the slurry. The cross-sectional area of ​​the first flow channel section 41 perpendicular to the flow direction gradually decreases along the flow direction, and the cross-sectional area of ​​the second flow channel section 42 perpendicular to the flow direction gradually increases along the flow direction. Therefore, the slurry is gradually compressed and squeezed after flowing into the first flow channel section 41, so that the slurry is continuously accelerated and a larger injection pressure is generated, thereby increasing the flow rate of the slurry. After flowing into the second flow channel section 42, the slurry gradually expands and expands outward to all sides. Therefore, by designing pressure changes in the shear channel 40 to extrude and expand the slurry, and shearing it through the stator and rotor 30, the dispersion effect and homogenization effect of the slurry are improved.

[0036] It should be noted that the “flow direction” of the slurry refers to the direction in which the slurry flows from the first flow channel section 41 to the second flow channel section 42 , that is, the direction in which the slurry flows from the inside to the outside along the radial direction Y of the dispersion mechanism 300 .

[0037] For the accuracy of description, please refer to the direction in this article. Figure 1 and Figure 2 For reference, the "axial direction X" refers to the direction parallel to Figure 1 The direction of the central axis P of the pulping tank 100 is the left-right direction (where the positive direction of the X axis is the left); the term "radial direction Y" refers to the direction perpendicular to Figure 2 The direction of the central axis P of the dispersion mechanism 300, that is, the radial direction along the cross section of the dispersion mechanism 300, is also the up-down direction (where the positive direction of the Y axis is upward); the term "circumferential direction Z" refers to Figure 2 The circumferential direction of the dispersion mechanism 300 is defined as the direction surrounding the central axis P of the dispersion mechanism 300. The axial direction X, radial direction Y, and circumferential direction Z collectively constitute the three orthogonal directions of the dispersion mechanism 300. The axial direction X, radial direction Y, and circumferential direction Z of the dispersion mechanism 300 can be customized based on the specific structure of the product and the perspective of the accompanying drawings, and are not specifically limited in this utility model. For ease of description, the directions of up, down, left, and right in this utility model are relative positions and do not constitute limitations.

[0038] For example, in this embodiment, the bottom of the tank body 110 is provided with a mounting hole 102 for mounting the dispersion mechanism 300. Specifically, the edge of the stator base 11 is sealedly connected to the mounting hole 102. The stator base 11 and the pulping tank 100 can be directly connected or fixedly connected via a third component, which is not specifically limited in this embodiment. Specifically, the stator base 11 includes a support base 111 and a connection base 112. The support base 111 is connected to the connection base 112 to form a dispersion chamber 301 that accommodates the rotor 30, thereby causing most of the slurry in the dispersion chamber 301 to be discharged from the dispersion mechanism 300 after being sheared by the stator ring 13 and the rotor ring 33. This prevents the slurry in the dispersion chamber 301 from leaking into the inner cavity of the pulping tank 100 without being sheared by the stator ring 13 and the rotor ring 33, and weakens the impact of the slurry outside the dispersion mechanism 300 on the internal structure of the dispersion mechanism 300, thereby reducing the energy loss of the fluid in the dispersion mechanism 300 and improving the circulation and dispersion capabilities of the dispersion mechanism 300. The edge of the support base 111 is sealed and connected to the mounting hole 102. The stator ring 13 is arranged on the side of the connection base 112 facing the support base 111.

[0039] Please also refer to Figure 2 and Figure 3 , Figure 3 yes Figure 1 sectional view of the second embodiment of the dispersion mechanism 300 of the pulping apparatus 1000. Figure 2 As shown in the first embodiment, the stator slot 1301 and the rotor slot 3301 are each configured with a first flow channel section 41 and a second flow channel section 42. This improves the shearing, squeezing, expansion and friction effects on the slurry, thereby improving the dispersing effect of the dispersing device. Figure 3 As shown, in the second embodiment, one of the adjacent stator slots 1301 and rotor slots 3301 is configured as the first flow channel section 41, and the other of the adjacent stator slots 1301 and rotor slots 3301 is configured as the second flow channel section 42. This facilitates the processing and manufacturing of the dispersion mechanism 300, improves production efficiency, and enhances the shearing effect of the slurry. Of course, in some embodiments, part of the stator ring 13 and part of the rotor ring 33 are provided with the first flow channel section 41 and the second flow channel section 42, and the remaining part of the adjacent stator slots 1301 and rotor slots 3301 is configured as the first flow channel section 41, and the other of the adjacent stator slots 1301 and rotor slots 3301 is configured as the second flow channel section 42. The arrangement of the first flow channel section 41 and the second flow channel section 42 can be set according to factors such as the viscosity or other characteristic parameters of the slurry, the size of the slurry tank 100, etc., and is not specifically limited in the embodiment of the utility model.

[0040] Please also refer to Figure 2 and Figure 3The first flow channel segments 41 and the second flow channel segments 42 are alternately arranged along the flow direction of the slurry. Thus, on the one hand, the slurry flows through the multiple first flow channel segments 41 and the multiple second flow channel segments 42, thereby enhancing the shearing, squeezing, expansion, and friction effects on the slurry, thereby improving the dispersing effect of the dispersing device. On the other hand, a high-pressure gradient is formed during the slurry's passage through the first flow channel segments 41 and the second flow channel segments 42, thereby accelerating the flow of the slurry and improving the dispersing efficiency of the dispersing mechanism 300.

[0041] See also Figure 4 , Figure 4 yes Figure 1 FIG. 1 is a cross-sectional view of a third embodiment of the dispersion mechanism 300 of the pulping apparatus 1000. In the third embodiment, the shear channel 40 further includes a third channel segment 44. The width of the third channel segment 44 along the circumferential direction Z of the dispersion mechanism 300 remains constant along the flow direction. The third channel segment 44, the first channel segment 41, and the second channel segment 42 are sequentially arranged along the flow direction of the slurry. Therefore, since the pressure component of the slurry increases in the flow direction of the slurry and the flow rate gradually decreases, a third flow channel section 44 is set upstream of the shear flow channel 40, and a first flow channel section 41 and a second flow channel section 42 are set downstream of the shear flow channel 40, so that the slurry is first sheared and dispersed in the third flow channel section 44, avoiding the problem of large particles in the slurry being blocked at the junction of the first flow channel section 41 and the second flow channel section 42, and the slurry dispersed in the third flow channel section 44 is gradually compressed and squeezed after entering the first flow channel section 41, so that the slurry is continuously accelerated and generates a larger injection pressure, thereby increasing the flow rate of the slurry, and then the slurry gradually expands and expands outward to all sides after entering the second flow channel section 42. Therefore, the pressure change of the shear flow channel 40 is designed to extrude, expand, and shear the slurry through the stator 10 and the rotor 30, thereby improving the dispersion effect and homogenization effect of the slurry.

[0042] Part of the stator slots 1301 and / or part of the rotor slots 3301 can be configured as the third flow channel segment 44, and the remaining part of the stator slots 1301 and / or the remaining part of the rotor slots 3301 can be configured as the first flow channel segment 41 and the second flow channel segment 42. For example, in the third embodiment, the stator 10 includes a stator ring 13, the rotor 30 includes two rotor rings 33, the third flow channel segment 44 is provided on the rotor ring 33 located on the innermost ring of the rotor base 31 and the stator ring 13, and the first flow channel segment 41 and the second flow channel segment 42 are provided on the rotor ring 33 located on the outermost ring of the rotor base 31.

[0043] Exemplarily, the centerline of the first flow channel section 41 is collinear with the centerline of the second flow channel section 42 and is parallel to the radial direction Y of the dispersion mechanism 300, thereby facilitating the processing and manufacturing of the stator 10 and the rotor 30. The centerline of the third flow channel section 44 is parallel to the radial direction Y of the dispersion mechanism 300, thereby facilitating the processing and manufacturing of the dispersion mechanism 300. Of course, in some embodiments, the centerline of the third flow channel section 44 forms an angle with the radial direction Y of the dispersion mechanism 300, thereby increasing the contact time between the liquid and powder during the dispersion process, and strengthening the shearing effect on the slurry, so that the slurry is better dispersed and mixed, thereby effectively improving the quality of the slurry product. The angle can be, but is not limited to, 10°-80°.

[0044] It should be noted that, in the present invention, descriptions such as parallel and perpendicular may include situations where the two lines are approximately parallel or perpendicular due to processing errors, measurement errors, etc. For example, the two lines being parallel herein may include situations where the two lines are completely parallel, and may also include situations where the two lines are approximately parallel, for example, the angle between the center line of the first flow channel segment 41 and the center line of the second flow channel segment 42 and the center line of the first flow channel segment 41 and the center line of the second flow channel segment 42 is 0°-5°.

[0045] It should be noted that the number of stator rings 13 and rotor rings 33 can be set according to actual conditions, and the present invention does not make specific restrictions. For example, the number of stator rings 13 and rotor rings 33 can be set to one, and one of the stator ring 13 and rotor ring 33 is provided with a third flow channel section 44, and the other of the stator ring 13 and rotor ring 33 is provided with a first flow channel section 41 and a second flow channel section 42; for another example, the number of stator rings 13 and rotor rings 33 is set to multiple, and the stator ring 13 and / or rotor ring 33 close to the central axis P of the dispersion mechanism 300 is provided with a third flow channel section 44, and the stator ring 13 and / or rotor ring 33 away from the central axis P of the dispersion mechanism 300 is provided with a first flow channel section 41 and a second flow channel section 42. In addition, the arrangement of the first flow channel section 41 and the second flow channel section 42 in the third embodiment can adopt the arrangement of the first flow channel section 41 and the second flow channel section 42 in the first embodiment or the arrangement of the first flow channel section 41 and the second flow channel section 42 in the second embodiment, and the embodiments of the present utility model do not make specific limitations.

[0046] Please refer again Figure 1 and Figure 3In some embodiments, multiple first flow channel segments 41 are provided, with the outermost first flow channel segment 41 located outside all second flow channel segments 42. As a result, the slurry is gradually compressed and squeezed after flowing into the first flow channel segment 41, causing the slurry to continuously accelerate and generate a higher injection pressure, increasing the slurry flow rate, thereby improving the discharge capacity of the dispersion mechanism 300 and enhancing the dispersion efficiency of the dispersion mechanism 300. Specifically, in this embodiment, the outermost first flow channel segment 41 can be provided on the rotor ring 33. This generates negative pressure during high-speed rotation of the outermost rotor ring 33, further accelerating the slurry in the first flow channel segment 41 and increasing the slurry flow rate. Furthermore, this increases the flow rate of the slurry ejected from the stator slots 1301 of the outermost stator ring 13, improving the material suction and discharge capabilities of the dispersion mechanism 300. Of course, in some embodiments, the outermost first flow channel segment 41 can also be provided on the stator ring 13. In this embodiment, each stator ring 13 is provided between two adjacent rotor rings 33. As a result, the rotor ring 33 can quickly eject the slurry in the rotor slot 3301 under high-speed rotation, thereby improving the slurry discharge effect of the dispersion mechanism 300 and improving the material absorption capacity of the dispersion mechanism 300. Specifically, the outermost rotor ring 33 is located on the inner side of the outermost stator ring 13. As a result, the outermost rotor ring 33 is located on the inner side of the outermost stator ring 13, which can reduce mechanical vibration, reduce airflow interference, and balance the dynamic load of the rotor 30 during mechanical operation, thereby reducing vibration and noise caused by imbalance, thereby reducing noise, and further reducing the noise generated by the dispersion mechanism 300 during the slurry dispersion process. In some embodiments, the outermost rotor ring 33 is located on the outer side of the outermost stator ring 13. Therefore, based on the fact that the outermost rotor ring 33 is located outside the outermost stator ring 13, the flow rate of the slurry sprayed from the stator slot 1301 of the outermost stator ring 13 is increased, the suction and discharge capabilities of the dispersion mechanism 300 are improved, the mixing and dispersion of the slurry are promoted, the dispersion efficiency of the dispersion mechanism 300 is improved, and the slurry can be better reciprocated in the pulping equipment 1000.

[0047] In some embodiments, the dispersion mechanism 300 further includes an impeller 50. The rotor ring 33 and the impeller 50 are disposed on the same side of the rotor base 31. The rotor 30 is disposed around the impeller 50, thereby improving the dispersion capability of the dispersion mechanism 300. Of course, in other embodiments, the impeller 50 may be disposed on both sides of the rotor base 31 in the axial direction X of the circulating pulping apparatus 1000. The rotor ring 33 may also be disposed on both sides of the rotor base 31 in the axial direction X of the pulping apparatus 1000.

[0048] In some embodiments, the radial dimension of the impeller 50 at the suction end is smaller than the radial dimension of the impeller 50 at the discharge end. Specifically, the impeller 50 is arranged in a roughly conical shape. The impeller 50 has a suction end away from the base of the rotor 30 and a discharge end arranged opposite to the suction end. The radial dimension of the impeller 50 gradually increases from the suction end to the discharge end. As a result, it is convenient to convert the kinetic energy of the compressed slurry into pressure energy, reduce the energy loss of the flow channel, and increase the speed of the slurry fluid at the discharge end, thereby improving the flow efficiency and flow output of the slurry fluid. Specifically, the impeller 50 includes a base 51 arranged on the base of the rotor 30 and a plurality of blades 52 arranged on the side wall of the base 51. The plurality of blades 52 are arranged at intervals along the rotation direction of the impeller 50. The base 51 can be configured as a truncated cone, and the blades 52 can be configured as twisted blades. As a result, the flow characteristics of the slurry can be better adapted, the rotational loss of the slurry fluid when passing through the blades 52 can be reduced, the slurry conveying efficiency can be improved, and the twisted blades can make the slurry fluid pass through the impeller 50 more evenly, reducing the impact and extrusion of the slurry fluid, thereby further reducing the vibration and noise of the dispersion mechanism. Specifically, the cross-section of the base 51 along the radial direction Y of the dispersion mechanism 300 gradually increases from the suction end toward the discharge end. The side wall of the base 51 is configured as a curved surface. The meridian flow line of the base 51 from the suction end to the discharge end is a curve that bends inward relative to the central axis of the base 51. The meridian flow line is roughly arc-shaped.

[0049] Of course, in other embodiments, the radial dimension of the impeller 50 at the intake end is equal to the radial dimension of the impeller 50 at the discharge end. For example, the impeller 50 may be substantially cylindrical. The radial dimension of the impeller 50 remains substantially constant from the intake end to the discharge end. The base 51 may be configured as a cylinder or a prism, and the blades 52 may be cylindrical. This facilitates the processing and manufacturing of the impeller 50, facilitates cleaning, and improves the operational stability of the impeller 50. For another example, the base 51 may be configured as a truncated cone, and the blades 52 may be cylindrical.

[0050] It should be noted that a cylindrical blade refers to a structure in which the surface of the blade 52 is unidirectionally curved. A cylindrical blade is also referred to as a single-curvature blade or an oblique blade. A twisted blade refers to a blade that gradually twists from bottom to top along its own height. In this embodiment, a twisted blade refers to a structure in which the surface of the blade 52 is bidirectionally curved. A cylindrical blade is also referred to as a spatially curved surface or a double-curvature blade.

[0051] In other embodiments, the blades 52 may also be, but are not limited to, linear blades. A linear blade refers to a structure in which the blade's shape and mounting angle remain constant throughout the blade height range, and the line connecting the centroids of the cross sections aligns with the radial direction of the impeller 50. Specifically, within a projection plane perpendicular to the central axis of the base 51, the impeller blades 52 extend from the inside outward in the radial direction of the impeller 50. For example, in some embodiments, within a projection plane parallel to the central axis of the base 51, the extension direction of the linear blades may be parallel to the central axis of the base 51. In other embodiments, within a projection plane parallel to the central axis of the base 51, the extension direction of the linear blades may intersect the central axis of the base 51. In other words, within a projection plane parallel to the central axis of the base 51, the extension direction of the linear blades may be arranged at an angle to the central axis of the base 51. The impeller blades 52 may also employ other blade structures that exhibit a centrifugal effect, which are not specifically limited in the present embodiments.

[0052] Please refer again Figure 2 and Figure 5 , Figure 5 yes Figure 2 An enlarged view of the first embodiment of part I of the dispersion mechanism 300 is shown. Along the flow direction of the slurry, the adjacent first flow channel sections 41 and the second flow channel sections 42 are arranged adjacent to each other, thereby facilitating the processing and manufacturing of the stator ring 13 or the rotor ring 33 and improving production efficiency; as well as improving the slurry injection effect, promoting the circulation movement of the slurry, and improving the uniformity and stability of the slurry.

[0053] Please refer again Figure 2 and Figure 6 , Figure 6 yes Figure 2 FIG2 is an enlarged view of a second embodiment of a dispersion mechanism 300 in section I. The shear channel 40 further includes a transitional connecting section 43. The width of the transitional connecting section 43 along the circumferential direction Z of the dispersion mechanism 300 remains constant along the flow direction. The adjacent first channel section 41 and second channel section 42 are connected by the transitional connecting section 43. This creates a sufficiently large frictional force between the slurry and the sidewall of the third channel section 44, promoting the extrusion and crushing of agglomerates, facilitating dispersion, and thereby improving the uniformity and stability of the slurry.

[0054] The length of the transition connecting section 43 in the flow direction is shorter than the length of the first flow channel section 41 in the flow direction and the length of the second flow channel section 42 in the flow direction, thereby reducing the risk of re-agglomeration between the particulate matter and the slurry solvent in the slurry, and improving the uniformity and stability of the slurry.

[0055] In this embodiment, the connection between the inner side wall of the first flow channel section 41 and the inner side wall of the second flow channel section 42 can be set at a sharp angle, thereby facilitating the processing and manufacturing of the stator ring 13 or the rotor ring 33 and improving production efficiency. Figure 2 and Figure 7 , Figure 7 yes Figure 2 An enlarged view of a third embodiment of a dispersion mechanism 300 in FIG. In some embodiments, the connection between the inner sidewall of the first flow channel section 41 and the inner sidewall of the second flow channel section 42 can also be configured as an arc. This, on the one hand, reduces the flow resistance of the slurry, increases the flow rate and smoothness of the slurry, improves the dispersion efficiency of the dispersion structure, and reduces the energy consumption of the dispersion structure. On the other hand, it improves the overall structural strength of the stator ring 13 or rotor ring 33, enhances the load-bearing capacity of the stator ring 13 or rotor ring 33, and improves the stability of the dispersion mechanism 300 in dispersing the slurry.

[0056] Please also refer to Figure 2 and Figure 8 , Figure 8 yes Figure 2 An enlarged view of a fourth embodiment of the dispersion mechanism 300 in FIG. The inner sidewall of the first flow channel section 41 and / or the inner sidewall of the second flow channel section 42 is provided with a shearing structure 46. Thus, the shearing structure 46 is used to provide shearing and breaking up forces to the slurry when the rotor 30 rotates relative to the stator 10, thereby improving the dispersion effect of the dispersion mechanism 300, increasing the contact area between the slurry and the dispersion mechanism 300, reducing the pressure exerted by the slurry on the dispersion structure, and increasing the service life of the dispersion mechanism 300. The shearing structure 46 can be recessed in the inner sidewall of the first flow channel section 41 and / or the inner sidewall of the second flow channel section 42; alternatively, it can be protruded in the inner sidewall of the first flow channel section 41 and / or the inner sidewall of the second flow channel section 42. One or more shearing structures 46 can be provided. The shearing structure 46 can be configured as, but is not limited to, at least one of convex points, concave points, spiral convex patterns, spiral concave patterns, annular convex patterns, and annular concave patterns. The shear structure 46 is streamlined, thereby reducing the flow resistance of the slurry, increasing the flow rate of the slurry and reducing the slurry residue on the side wall of the stator 10 or the rotor 30 .

[0057] Optionally, in this embodiment, the shearing structure 46 is integrally formed with the stator 10 or the rotor 30 to increase the structural stability of the shearing structure 46 and the stator 10 or the rotor 30, thereby improving the dispersion stability of the dispersion mechanism 300. Of course, in some embodiments, the shearing structure 46 and the stator 10 or the rotor 30 are detachably connected to each other, so that the shearing structure 46 can be installed in different areas of the stator 10 or the rotor 30 according to actual needs.

[0058] Please also refer to Figures 5 to 8In this embodiment, the inner side wall of the first flow channel section 41 and / or the inner side wall of the second flow channel section 42 can be configured as a plane. This facilitates the processing and manufacturing of the stator ring 13 and the rotor ring 33. In some other embodiments, the inner side wall of the first flow channel section 41 and / or the inner side wall of the second flow channel section 42 can also be configured as a curved surface. Therefore, based on setting the inner side wall of the first flow channel section 41 and the inner side wall of the second flow channel section 42 as a curved surface, on the one hand, the contact area between the slurry and the inner side wall of the first flow channel section 41 and the inner side wall of the second flow channel section 42 is increased, the shear effect and friction effect of the slurry are improved, and the dispersion effect is improved; on the other hand, compared with the plane design, the curved surface design can increase the flow rate of the slurry in the first flow channel section 41 and the second flow channel section 42.

[0059] The first flow channel segment 41 and the second flow channel segment 42 can each have a V-shape or a truncated cone. Specifically, the first flow channel segment 41 has a fan-shaped cross-section perpendicular to the axial direction X of the dispersion mechanism 300, while the second flow channel segment 42 has a fan-shaped cross-section perpendicular to the height of the dispersion mechanism 300. This facilitates the processing and manufacturing of the stator ring 13 and the rotor ring 33. Of course, in some embodiments, the first flow channel segment 41 and the second flow channel segment 42 can also have, but are not limited to, regular shapes such as truncated pyramids or other special shapes.
