[0040] 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.

[0041] See also Figure 1 , Figure 1 It is a cross-sectional view of the pulping equipment 1000 provided in the first embodiment of the present invention. The pulping equipment 1000 includes a pulping tank 100 and a dispersion mechanism 300. The dispersion mechanism 300 is arranged in the pulping tank 100 and is used to disperse the slurry. Thus, on the one hand, the dispersion mechanism 300 is used to shear and disperse the slurry, and the slurry thrown out by the dispersion mechanism 300 flows toward the side wall of the pulping tank 100, and then flows upward along the side wall of the pulping tank 100, forming a reciprocating flow path, thereby improving the dispersion ability and circulation ability of the pulping equipment 1000; on the other hand, the slurry is circulated in the interior of a single pulping tank 100 through the dispersion mechanism 300, eliminating the circulation pipe and the circulation pump, and the slurry flow resistance is small, meeting the requirements of large-flow circulation pulping.

[0042] For example, in this embodiment, the pulping tank 100 is provided with a circulation chamber 101. The circulation chamber 101 is used to accommodate slurry. The dispersion mechanism 300 is provided at the bottom of the pulping tank 100 and is located in the circulation chamber 101, thereby facilitating the assembly of the dispersion mechanism 300, improving the stability and reliability of the connection between the dispersion mechanism 300 and the pulping tank 100, and improving the stability and reliability of the dispersion mechanism 300 during dispersion work. Of course, in some embodiments, the dispersion mechanism 300 can also be provided at other positions of the pulping tank 100, for example, in the middle of the pulping tank 100. Of course, in some embodiments, the pulping equipment 1000 can omit the pulping tank 100, that is, the pulping equipment 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.

[0043] In this embodiment, the central axis of the dispersion mechanism 300 is coaxially arranged with the central axis P of the pulping tank 100, so that the slurry maintains a relatively stable circulation trajectory during the dispersion process of the dispersion mechanism 300, thereby achieving uniform stirring of the slurry by the dispersion mechanism 300, while reducing the energy consumption of the dispersion mechanism 300, reducing production costs, and making the dispersion mechanism 300 occupy less space in the pulping tank 100, thereby improving the compactness of the structure. Of course, in some embodiments, the central axis of the dispersion mechanism 300 is separated from the central axis P of the pulping tank 100 by a preset distance, so that when the dispersion mechanism 300 performs the dispersion work, the slurry forms slurry flow layers of different speeds due to the radial asymmetric distribution, reducing the formation of large particle agglomerates, avoiding impact on the components of the pulping equipment 1000, reducing vibration and noise, and improving the mixing and dispersion effects of the slurry. The preset distance can be set according to actual conditions and is not specifically limited in the embodiments of the present utility model.

[0044] The slurry can be a battery slurry. The battery slurry is a solid-liquid mixture. The 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. The liquid can also include a liquid 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.

[0045] 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 body 110 and the tank cover 120 are detachably connected, thereby facilitating assembly, maintenance, tilting, and other operations of the various components of the pulping equipment 1000. Specifically, the dispersion mechanism 300 is disposed at the bottom of the tank body 110, facing away from the tank cover 120. This facilitates assembly of the dispersion mechanism 300 with the pulping tank 100, resulting in a rational layout and compact structure, and convenient cleaning and maintenance of the components of the pulping equipment 1000.

[0046] 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.

[0047] In some embodiments, the slurrying apparatus 1000 further includes a powder conveying mechanism. The powder conveying mechanism can be disposed on the tank lid 120 or on the tank body 110. The powder conveying mechanism can include, but is not limited to, a feeding screw or a rotary valve, thereby achieving uniform feeding of the powder conveying mechanism and improving the uniformity of slurry mixing. Of course, in some embodiments, a powder dispersing mechanism is provided along the transmission path of the powder conveying mechanism to improve the wetting effect of the liquid on the powder, reduce wear on the dispersion mechanism 300, and improve the dispersion efficiency of the dispersion mechanism 300.

[0048] The pulping apparatus 1000 also includes a liquid material conveying mechanism. This mechanism is disposed on the tank cover 120 or the tank body 110. Optionally, a guide mechanism is provided along the liquid material conveying path. This guide mechanism is used to direct the liquid material to a designated location within the pulping tank 100. For example, the guide mechanism can direct the liquid material to the vicinity of the dispersion mechanism 300. The liquid material dispersed by the dispersion mechanism 300 then comes into contact with and infiltrates the powder material, thereby enhancing mixing and dispersion.

[0049] 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 pulping device 1000. 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, such as the pulping apparatus 1000 may further include, but not limited to, temperature sensors, etc. The temperature sensor is used to detect the temperature of the pulp in the pulping tank 100 .

[0050] For the accuracy of description, please refer to the direction in this article. Figure 1For reference, the "axial direction X" refers to the direction parallel to the central axis P of the pulping tank 100, that is, the left-right direction (where the positive direction of the X axis is left); the term "radial direction Y" refers to the direction perpendicular to the central axis P of the pulping tank 100, that is, the radial direction along the cross-section of the pulping tank 100, and is also the up-down direction (where the positive direction of the Y axis is up); the term "circumferential direction Z" refers to the circumferential direction of the pulping tank 100, that is, the direction surrounding the central axis P of the pulping tank 100, wherein the axial direction X, radial direction Y and circumferential direction Z together constitute the three orthogonal directions of the pulping tank 100. The axial direction X, radial direction Y and circumferential direction Z of the pulping tank 100 can be customized according to the specific structure of the product and the perspective of the drawings, and this utility model does not make specific restrictions. For the convenience of description, the directions such as up, down, left and right in this utility model are relative positions and do not constitute a limitation to the implementation.

[0051] 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 rotor 10 and a stator 30. The rotor 10 includes a rotor base 11 and a rotor ring 13 disposed on the rotor base 11. The stator 30 includes a stator base 31 and a stator ring 33 disposed on the stator base 31. The rotor ring 13 and the stator ring 33 are alternately disposed along the radial direction Y of the dispersion mechanism 300 and are rotationally engaged. The rotor ring 13 and the stator ring 33 are each provided with a channel group 305, and the volume of all channel groups 305 gradually decreases from the inside to the outside along the radial direction (Y) of the dispersion mechanism 300.

[0052] The dispersion mechanism 300 provided in the embodiment of the present invention is based on the setting of multiple channel groups 305 whose volumes gradually decrease from the inside to the outside, so that a large pressure difference is generated between the inside and outside of the dispersion mechanism 300, so that the slurry can be gradually compressed and squeezed in the process of flowing through the multiple channel groups 305, so that the slurry is continuously accelerated and a large injection pressure is generated, thereby increasing the flow rate of the slurry, thereby improving the dispersion efficiency and dispersion effect of the dispersion mechanism 300 on the slurry.

[0053] It should be noted that, in some embodiments, the volumes of some of the channel groups 305 arranged continuously along the radial direction Y of the dispersion mechanism 300 gradually decrease from the inside out. For example, the volume of the innermost channel group 305 and its adjacent channel groups 305 are the same; and / or the volume of the innermost channel group 305 and its adjacent channel groups 305 are the same.

[0054] Each channel group 305 includes multiple shear channels 301. The multiple shear channels 301 are spaced apart along the circumferential direction Z of the dispersion mechanism 300. Specifically, the multiple shear channels 301 provided on the rotor ring 13 are evenly and spaced apart along the circumferential direction Z of the dispersion mechanism 300. All the shear channels 301 on the same rotor ring 13 form one channel group 305. The multiple shear channels 301 provided on the stator ring 33 are also evenly and spaced apart along the circumferential direction Z of the dispersion mechanism 300. All the shear channels 301 on the same stator ring 33 form another channel group 305. This ensures that shear, friction, and impact forces acting on the material are more uniform, which helps improve dispersion efficiency and uniformity. Furthermore, the evenly distributed shear channels 301 can reduce wear on the dispersion mechanism 300 and extend its service life. The number of rotor rings 13 and the number of stator rings 33 can each be one or more, and this is not specifically limited in this embodiment of the present invention. The sum of the number of rotor rings 13 and the number of stator rings 33 is the number of channel groups 305. A shear gap 303 is formed between adjacent rotor rings 13 and stator rings 33. Two adjacent channel groups 305 are connected through the shear gap 303, thereby increasing the shear and friction effects on the slurry in the shear gap 303, improving dispersion efficiency, and ensuring the reliability of high-speed rotation of the rotor ring 13.

[0055] In the first embodiment, all shearing channels 301 in the same channel group 305 have the same volume. Therefore, by setting the shearing channels 301 in the same channel group 305 to have the same volume, the evenly distributed shearing channels 301 ensure that the material is evenly distributed between the high-speed rotating rotor ring 13 and stator ring 33, making the shearing, friction, and impact forces on the material more uniform, thereby improving dispersion efficiency and uniformity. Furthermore, the evenly distributed shearing channels 301 can reduce wear on the dispersion mechanism 300 and extend the service life of the dispersion mechanism 300.

[0056] It should be noted that, in the embodiments of the present application, descriptions such as the same volume, the same length, or the same cross-section may include situations where the volumes are approximately the same due to processing errors, measurement errors, etc. For example, the same volume of all shearing channels 301 includes the situation where the volumes of any two shearing channels 301 are the same, and may also include the situation where the volumes of any two shearing channels 301 are approximately the same.

[0057] The number of shear channels 301 in any two adjacent channel groups 305 is the same. Specifically, when the rotor ring 13 rotates to a specified position relative to the stator ring 33, the multiple shear channels 301 provided on the rotor ring 13 communicate with the multiple shear channels 301 provided on the stator ring 33 in a one-to-one correspondence. Thus, by providing the same number of shear channels 301 in any two adjacent channel groups 305, the material is ensured to be subjected to more uniform and sufficient shearing and friction in the shear gap 303 formed between the rotor ring 13 and the stator ring 33, thereby improving dispersion efficiency and facilitating the processing and manufacturing of the rotor ring 13 and the stator ring 33.

[0058] Along the radial direction Y of the dispersion mechanism 300, any shear channel 301 of the stator ring 33 communicates with a corresponding shear channel 301 of the rotor ring 13 to form a flow channel group 306. The volume of the multiple shear channels 301 in the flow channel group 306 gradually decreases from the inside to the outside along the radial direction Y of the dispersion mechanism 300. As a result, the volume of the multiple channel groups 305 gradually decreases from the inside to the outside, creating a large pressure difference between the inside and outside of the dispersion mechanism 300. As a result, the slurry is gradually compressed and squeezed as it flows through the multiple channel groups 305, continuously accelerating the slurry and generating a large injection pressure, increasing the slurry flow rate, and thereby improving the dispersion efficiency and effect of the dispersion mechanism 300 on the slurry.

[0059] It should be noted that the volume of the channel group 305 refers to the sum of the volumes of all the shear channels 301 of the same channel group 305. When the shape of the shear channel 301 is regular, the volume of each shear channel 301 is related to the length of the shear channel 301 along the slurry flow direction and the area of ​​the cross section of the shear channel 301 perpendicular to the slurry flow direction. Specifically, when the shear channel 301 is a truncated cone, the volume of the shear channel 301 satisfies the following formula: V = 1 / 3h(S1+S2+√(S1*S2)), wherein V is the volume of the shear channel 301, h is the height of the truncated cone, S1 is the upper base area of ​​the truncated cone, and S2 is the lower base area of ​​the truncated cone. The cross section of the shear channel 301 perpendicular to the slurry flow direction refers to the cross section of the shear channel 301 along the radial direction Y of the dispersion mechanism 300. When the extension direction of the shear channel 301 is parallel to the radial direction Y of the dispersion mechanism 300 and the shear channel 301 is cylindrical, the volume of each shear channel 301 is roughly equal to the product of the length of the shear channel 301 along the radial direction Y of the dispersion mechanism 300 and the area of ​​the cross section of the shear channel 301 along the circumferential direction Z of the dispersion mechanism 300.

[0060] In the first embodiment, the length of the multiple shear channels 301 in each flow channel group 306 along the slurry flow direction remains constant from the inside out, while the cross-sectional area of ​​the multiple shear channels 301 in each flow channel group 306 along the cross-sectional area perpendicular to the slurry flow direction gradually decreases from the inside out. Specifically, along the radial direction Y of the dispersion mechanism 300, the thickness of the rotor ring 13 in the radial direction Y of the dispersion mechanism 300 is equal to the thickness of the stator ring 33 in the radial direction Y of the dispersion mechanism 300. The slurry flow direction is substantially parallel to the radial direction Y of the dispersion mechanism 300. Therefore, on the one hand, the thickness of the rotor ring 13 and the stator ring 33 are kept consistent, which facilitates the assembly and processing of the rotor ring 13 and the stator ring 33; on the other hand, the area of ​​the cross section perpendicular to the slurry flow direction is gradually reduced from the inside to the outside, so that the slurry can be gradually compressed and squeezed in the process of flowing through the multiple channel groups 305, so that the slurry is continuously accelerated and a larger injection pressure is generated, thereby increasing the flow rate of the slurry, thereby improving the dispersion efficiency and dispersion effect of the dispersion mechanism 300 on the slurry.

[0061] Please also refer to Figure 1 and Figure 3 , Figure 3 yes Figure 1 A cross-sectional view of a second embodiment of the dispersion mechanism 300 of the pulping apparatus 1000 is shown. In the second embodiment, the length of the multiple shear channels 301 in each flow channel group 306 along the slurry flow direction gradually decreases from the inside out, while the cross-sectional area of ​​the multiple shear channels 301 in each flow channel group 306 along the cross-sectional area perpendicular to the slurry flow direction remains constant from the inside out. This improves the manufacturing of the shear channels 301 and the uniform and sufficient shear and friction applied to the material within the shear channels 301, thereby enhancing dispersion efficiency.

[0062] In this embodiment, within the plurality of channel groups 305, the rotor ring 13 corresponding to the inner shear channel 301 has a greater thickness in the radial direction Y of the dispersion mechanism 300 than the stator ring 33 corresponding to the outer shear channel 301; alternatively, the stator ring 33 corresponding to the inner shear channel 301 has a greater thickness in the radial direction Y of the dispersion mechanism 300 than the rotor ring 13 corresponding to the outer shear channel 301. Specifically, two rotor rings 13 are provided, and one stator ring 33 is provided. The stator ring 33 is located between the two rotor rings 13, and its thickness in the radial direction Y of the dispersion mechanism 300 is greater than the thickness of the outermost rotor ring 13 in the radial direction Y of the dispersion mechanism 300, and less than the thickness of the innermost rotor ring 13 in the radial direction Y of the dispersion mechanism 300. Of course, in some embodiments, one rotor ring 13 is provided, and two stator rings 33 are provided. The rotor ring 13 is located between the two stator rings 33. The thickness of the rotor ring 13 in the radial direction Y of the dispersion mechanism 300 is greater than the thickness of the stator ring 33 located at the outermost side in the radial direction Y of the dispersion mechanism 300, and is less than the thickness of the stator ring 33 located at the innermost side in the radial direction Y of the dispersion mechanism 300.

[0063] It should be noted that the number of rotor rings 13 and stator rings 33 described above is for illustrative purposes only and is not specifically limited in the present embodiment. The placement of the stator rings 33 and rotor rings 13 can also be adjusted based on actual conditions, as long as the thickness of the stator rings 33 and the thickness of the rotor rings 13 gradually decrease from the inside out, thereby achieving a gradual decrease in the length of the multiple shear channels 301 perpendicular to the slurry flow direction from the inside out.

[0064] See also Figure 4 , Figure 4 yes Figure 1 FIG3 is a cross-sectional view of a third embodiment of the dispersion mechanism 300 of the pulping apparatus 1000 in FIG3 . In the third embodiment, the thickness of the rotor ring 13 in the radial direction Y of the dispersion mechanism 300 is equal to the thickness of the stator ring 33 in the radial direction Y of the dispersion mechanism 300. Within the plurality of channel groups 305, the inclination angle of the inner shearing channels 301 relative to the radial direction Y of the dispersion mechanism 300 is greater than the inclination angle of the outer shearing channels 301 relative to the radial direction Y of the dispersion mechanism 300, thereby achieving a gradual decrease in the length of the plurality of shearing channels 301 perpendicular to the slurry flow direction from the inside out.

[0065] Of course, in some embodiments, the length of the multiple shear channels 301 in each flow channel group 306 along the slurry flow direction gradually decreases from the inside to the outside, and the area of ​​the multiple shear channels 301 in each flow channel group 306 along the cross-section perpendicular to the slurry flow direction gradually decreases from the inside to the outside.

[0066] See also Figure 5 , Figure 5 yes Figure 1 A cross-sectional view of a fourth embodiment of the dispersion mechanism 300 of the pulping apparatus 1000 in FIG. In the fourth embodiment, any two adjacent channel groups 305 have different numbers of shear channels 301, and the volume of the multiple channel groups 305 gradually decreases from the inside out. This creates a large pressure difference between the inside and outside of the dispersion mechanism 300, gradually compressing and squeezing the slurry as it flows through the multiple channel groups 305. This continuously accelerates the slurry and generates a high injection pressure, increasing the slurry flow rate and, in turn, improving the dispersion efficiency and effectiveness of the dispersion mechanism 300.

[0067] In this embodiment, all shear channels 301 in the same channel group 305 have the same volume. The volumes of the multiple shear channels 301 in the flow channel group 306 remain constant from the inside out. Specifically, the lengths of the multiple shear channels 301 in the flow channel group 306 along the slurry flow direction remain constant from the inside out, and the cross-sectional areas of the multiple shear channels 301 in the flow channel group 306 along the cross-sectional area perpendicular to the slurry flow direction remain constant from the inside out. Of course, in other embodiments, the volumes of the multiple shear channels 301 in the flow channel group 306 may also gradually decrease from the inside out.

[0068] In some embodiments, any two adjacent channel groups 305 include a first channel group 3051 and a second channel group 3052. The first channel group 3051 has a greater number of shear channels 301 than the second channel group 3052. The first channel group 3051 is provided on the stator 33, while the second channel group 3052 is provided on the rotor 13. Therefore, since the number of shear channels 301 provided on the stator ring 33 is greater than the number of shear channels 301 provided on the rotor ring 13, the contact area and duration between the material and the shear channels 301 provided on the stator ring 33 are increased, thereby improving dispersion efficiency and uniformity, and increasing the intensity of the turbulent zone formed by the slurry at the edge of the dispersion mechanism 300, thereby increasing the shear and impact force of the dispersion mechanism 300 on the slurry and enhancing the dispersion effect. Furthermore, the increased number of shear channels 301 provided on the stator ring 33 also promotes the circulation and tumbling of the slurry around the dispersion mechanism 300.

[0069] Please refer again Figure 2In the same channel group 305, the cross-sectional area of ​​each shear channel 301 perpendicular to the slurry flow direction gradually decreases from the inside to the outside, so that the slurry can be gradually compressed and squeezed during the process of flowing through the channel group 305, so that the slurry is continuously accelerated and a larger injection pressure is generated, thereby increasing the flow rate of the slurry and further improving the dispersion efficiency and dispersion effect of the dispersion mechanism 300 on the slurry. Figures 3 to 6 As shown, Figure 6 yes Figure 1 1 is a cross-sectional view of a fifth embodiment of the dispersion mechanism 300 of the pulping apparatus 1000. In the same channel group 305, the area of ​​the cross section of each shear channel 301 perpendicular to the pulp flow direction remains constant from the inside to the outside.

[0070] The cross-sectional profile 3011 of the plurality of shear channels 301 perpendicular to the slurry flow direction may be, but is not limited to, fan-shaped, parallelogram-shaped, rectangular, trapezoidal or hourglass-shaped. Figure 2 As shown, the cross-sectional profile 3011 of the shear channel 301 perpendicular to the slurry flow direction is generally fan-shaped. Figure 3 and Figure 4 As shown, the cross-sectional profile 3011 of the shear channel 301 perpendicular to the slurry flow direction is generally parallelogram-shaped. Figure 5 and Figure 6 As shown, the cross-sectional profile 3011 of the shear channel 301 perpendicular to the slurry flow direction is substantially rectangular. The cross-sectional profile 3011 of the shear channel 301 perpendicular to the slurry flow direction can be set according to actual conditions and is not specifically limited in the embodiment of the present invention.

[0071] The shear channel 301 includes a first side 3012 and a second side 3013 along a cross-sectional profile 3011 perpendicular to the slurry flow direction. The first side 3012 and the second side 3013 are arranged along the circumferential direction Z of the dispersion mechanism 300. Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the first side 3012 and the second side 3013 are straight lines. Figure 4 As shown, the first side 3012 and the second side 3013 are in an arc shape. Of course, in some embodiments, the first side 3012 and the second side 3013 can also be in a sawtooth shape or a wavy shape.

[0072] The dispersion mechanism 300 also includes a rotating shaft 21 and a driving member 22. The rotating shaft 21 is connected to the rotor 10. The driving member 22 is used to drive the rotor 10 to rotate around the central axis P of the rotating shaft 21, so that the dispersion mechanism 300 can disperse the slurry in the pulping tank 100. The dispersion mechanism 300 also includes a limiting member 23, one end of the rotating shaft 21 is connected to the driving member 22, and the other end of the rotating shaft 21 is connected to the limiting member 23. The limiting member 23 is used to limit the installation position of the rotor 10 relative to the rotating shaft 21, thereby preventing the rotor 10 from vibrating and shaking relative to the rotating shaft 21, improving the stability of the rotating shaft 21, ensuring the smooth operation of the dispersion mechanism 300, reducing the wear of the dispersion mechanism 300 by the slurry; and facilitating the installation of the rotor 10 and the rotating shaft 21.

[0073] In some embodiments, the limiter 23 includes a connecting section and a free end that are relatively arranged along the axial direction X of the pulping equipment 1000. The connecting end of the limiter 23 is detachably fixedly connected to the rotating shaft 21 through a connecting shaft. Of course, in some embodiments, the limiter 23 and the rotating shaft 21 can also be formed as one piece. A conical head 232 is provided at the free end of the limiter 23. Therefore, on the one hand, the conical head 232 can divert the slurry fluid, reduce the resistance of the rotating shaft 21 during the rotation process, reduce energy consumption, and thus avoid the problem of reduced flow rate of the slurry fluid due to flow field interference; on the other hand, the conical head 232 can buffer and disperse the material to avoid deformation of the rotating shaft 21 due to the impact of the material; on the other hand, the conical head 232 can also break up the agglomerates in the slurry to ensure the quality and consistency of pulping.

[0074] In some embodiments, the rotor ring 13 is provided as one or more. The ratio of the diameter of the rotor ring 13 located at the outermost side of the rotor base 11 to the inner diameter of the pulping tank 100 is greater than or equal to 0.1. Thus, on the one hand, based on the setting of the ratio of the diameter of the rotor ring 13 located at the outermost side of the rotor base 11 to the inner diameter of the pulping tank 100 being greater than or equal to 0.1, the problem of the slurry being quickly dispersed to the suction end near the dispersion mechanism 300 after being sucked into the dispersion mechanism 300, which causes the negative pressure in the dispersion mechanism 300 to decrease, is avoided. The height of the slurry rising along the inner wall of the pulping tank 100 and the speed of the slurry rotating in the pulping tank 100 are relatively high, thereby improving the circulation capacity and dispersion capacity of the dispersion mechanism 300; on the other hand, the rotor ring 13 rotates in conjunction with the stator ring 33, thereby improving the shearing capacity of the slurry and improving the dispersion effect.

[0075] It can be understood that when the ratio of the diameter of the rotor ring 13 located at the outermost side of the rotor base 11 to the inner diameter of the pulping tank 100 is too small, the linear speed of the rotor 10 is also relatively small, and the shear force that the rotor 10 can generate is small, which makes the stirring and mixing effect of the slurry poor. At the same time, the insufficient dispersion ability of the dispersion mechanism 300 can easily cause the slurry to deposit at the bottom of the pulping tank 100, resulting in poor circulation ability of the slurry and reducing the product quality of the slurry. On the other hand, the small diameter of the rotor ring 13 can easily cause the slurry to be blocked in the dispersion mechanism 300. In the embodiment of the present invention, the ratio of the diameter of the rotor ring 13 located at the outermost side of the rotor base 11 to the inner diameter of the pulping tank 100 is greater than or equal to 0.1, thereby ensuring that the linear velocity of the rotor 10 is relatively high, and the slurry is fully dispersed, sheared, homogenized, and crushed in the dispersion mechanism 300, avoiding the insufficient dispersion capacity of the dispersion mechanism 300 which easily causes the slurry to deposit at the bottom of the pulping tank 100, and promoting the slurry to perform reciprocating circulation, reducing the slurry mixing time, and avoiding the risk of slurry blockage in the dispersion mechanism 300 due to the small diameter of the rotor ring 13, thereby improving the dispersion capacity of the dispersion mechanism 300 for the slurry and improving the product quality of the slurry; on the other hand, the slurry can generate a higher shear force under the rotation of the rotor 10 at a high linear velocity, which reduces the viscosity of the slurry, thereby accelerating the transmission speed of the slurry, making the slurry easier to flow, improving the discharge capacity of the dispersion mechanism 300, and promoting the reciprocating circulation of the slurry. Optionally, in some embodiments, the ratio of the diameter of the rotor ring 13 located at the outermost side of the rotor base 11 to the inner diameter of the pulping tank 100 is greater than or equal to 0.2.

[0076] The ratio of the diameter of the rotor ring 13 located on the outermost side of the rotor base 11 to the inner diameter of the slurry tank 100 is less than or equal to 0.9. It is understandable that when the diameter of the outermost rotor ring 13 is too large, the linear velocity of the rotor 10 is also relatively large, and the shear force generated by the rotor 10 is relatively large. However, during the rotation of the rotor 10, not only does it increase the energy consumption of the dispersion mechanism 300, but it also easily causes gas-liquid exchange in the slurry, resulting in the generation of bubbles, which has little effect on the stirring of the slurry. In the embodiment of the present invention, the ratio of the diameter of the rotor ring 13 located at the outermost side of the rotor base 11 to the inner diameter of the pulping tank 100 is in the range of 0.1 to 0.9, thereby ensuring a relatively high linear velocity of the rotor 10, and promoting sufficient dispersion, shearing, homogenization, and crushing of the slurry in the dispersion mechanism 300, thereby reducing the slurry preparation time and improving the dispersion ability of the dispersion mechanism 300 on the slurry, promoting the slurry discharged from the dispersion mechanism 300 to have an upward trend, increasing the dispersion of the slurry while making it less likely for the slurry to settle at the bottom of the pulping tank 100, and reducing product energy consumption. It also avoids the generation of bubbles in the dispersion mechanism 300 during the dispersion process, and improves the product quality of the slurry.

[0077] For example, the ratio of the diameter of the rotor ring 13 located at the outermost side of the rotor base 11 to the inner diameter of the pulping tank 100 may also be, but is not limited to, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, or 0.8. It should be noted that the ratio of the diameter of the rotor ring 13 located at the outermost side of the rotor base 11 to the inner diameter of the pulping tank 100 can be set according to factors such as the size parameters of the pulping tank 100, the volume and viscosity of the slurry to be dispersed, and is not specifically limited in the embodiments of the present invention.

[0078] For example, in this embodiment, the stator ring 33 located at the outermost side of the stator base 31 is located outside all the rotor rings 13. As a result, when the rotor 10 rotates at high speed, the slurry can form a specific flow path in the slurry tank 100 through the guidance of the stator ring 33, better controlling the flow of the slurry and ensuring that the slurry is subjected to stronger hydraulic shearing, centrifugal extrusion, high-speed cutting, impact and grinding when passing through the gap between the rotor 10 and the stator 30, thereby improving the dispersion and mixing effects of the dispersion mechanism 300; on the other hand, the outermost side of the dispersion mechanism 300 is set to the rotor ring 13, thereby increasing the slurry flow rate ejected by the shear channel 301 of the outermost stator ring 33, improving the material suction and discharge capacity of the dispersion mechanism 300, promoting the mixing and dispersion of the slurry, improving the dispersion efficiency of the dispersion mechanism 300, and better realizing the slurry to circulate and reciprocate in the slurry tank 100.

[0079] In some embodiments, the rotor ring 13 located at the outermost side of the rotor base 11 is located on the inner side of the outermost stator ring 33, thereby reducing mechanical vibration, reducing airflow interference, and balancing the dynamic load of the rotor 10 during mechanical operation, reducing vibration and noise caused by imbalance, thereby reducing noise, and further reducing the noise generated by the dispersion mechanism 300 during the process of dispersing the slurry.

[0080] Please also refer to Figure 1 and Figure 7 , Figure 7 yes Figure 1sectional view of the fifth embodiment of the dispersion mechanism 300 of the pulping equipment 1000 in FIG. The thickness of the rotor ring 13 along the radial direction Y of the pulping equipment 1000 is a first thickness D1, and the thickness of the stator ring 33 along the radial direction Y of the pulping equipment 1000 is a second thickness D2. The ratio of the first thickness D1 to the shear gap 303 is greater than or equal to 1.5; and / or, the ratio of the first thickness D1 to the shear gap 303 is less than or equal to 5; and / or, the ratio of the first thickness D1 to the second thickness D2 is greater than or equal to 1.5. It can be understood that when the ratio of the thickness of the rotor ring 13 to the shear gap 303 is large, it indicates that the thickness of the rotor ring 13 is relatively thick and the shear gap 303 is relatively small, so that the smaller gap can increase the flow velocity of the slurry during the dispersion process, thereby improving the dispersion effect and mixing effect of the slurry. When the ratio of the thickness of the stator ring 33 to the shear gap 303 is too large, the space of the shear area of ​​the dispersion mechanism 300 becomes smaller, thereby limiting the range and intensity of the shear force, and further affecting the uniformity and efficiency of the slurry dispersion; when the ratio of the thickness of the stator ring 33 to the shear gap 303 is small, it indicates that the thickness of the stator ring 33 is relatively thin and the shear gap 303 is relatively large. The friction force to which the slurry is subjected when passing through this gap will be more intense, thereby helping to better disperse powder materials such as solid particles in the slurry in the liquid material, thereby improving the uniformity of the slurry. At the same time, the setting of a smaller ratio of the thickness of the stator ring 33 to the shear gap 303 can also increase the shear rate of the dispersion mechanism 300, thereby enhancing the shear force and achieving a better mixing and dispersion effect of the slurry. When the ratio of the thickness of the rotor ring 13 to the thickness of the stator ring 33 is large, it indicates that the thickness of the rotor ring 13 is thicker than that of the stator ring 33. Therefore, the increase in the thickness of the rotor ring 13 enables the rotor 10 to provide greater shear force during rotation, effectively breaking up large particles and agglomerates in the slurry, helping to improve the dispersion efficiency, and at the same time enhancing the stirring intensity, so that the materials in the slurry are more fully mixed, thereby improving the uniformity of dispersion. The embodiment of the present utility model improves the dispersion effect and dispersion efficiency of the slurry by the dispersion mechanism 300, accelerates the transmission efficiency of the slurry in the dispersion mechanism 300, promotes the slurry to flow more easily, improves the material absorption and discharge capabilities of the dispersion mechanism 300, and promotes the reciprocating circulation of the slurry in the slurry tank 100 by reasonably setting the ratio of the thickness of the rotor ring 13 along the radial direction Y of the slurry making equipment 1000 to the shear gap 303 between the adjacent rotor ring 13 and the stator ring 33, and the ratio of the thickness of the rotor ring 13 along the radial direction Y of the slurry making equipment 1000 to the thickness of the stator ring 33 along the radial direction Y of the slurry making equipment 1000.

[0081] Optionally, in some embodiments, the ratio of the first thickness D1 to the shear gap 303 is greater than or equal to 3; and / or, the ratio of the second thickness D2 to the shear gap 303 is less than or equal to 2; and / or, the ratio of the first thickness D1 to the second thickness D2 is greater than or equal to 2, thereby further improving the dispersion effect and dispersion efficiency of the dispersion mechanism 300 on the slurry, and improving the reciprocating circulation ability of the slurry in the slurry tank 100.

[0082] In some embodiments, the shear channel 301 provided on the rotor ring 13 is defined as a first shear channel 131. Specifically, the rotor ring 13 is provided with a plurality of first shear channels 131 along the circumferential direction Z of the dispersion mechanism 300. The plurality of first shear channels 131 are arranged at intervals. The slot ratio of the first shear channel 131 is greater than or equal to 0.2. It can be understood that when the slot ratio of the first shear channel 131 is too small, the contact area between the rotor 10 and the slurry is also reduced, thereby affecting the generation of shear force, and the shear efficiency and dispersion uniformity of the dispersion mechanism 300 are poor. The utility model sets the slot ratio of the first shear channel 131 to be greater than or equal to 0.2. On the one hand, it can ensure the uniform distribution of shear force and avoid the phenomenon of damage to the structure of each material in the slurry. At the same time, it enhances the shear strength of the rotor ring 13, promotes the uniform dispersion of the slurry, and thereby improves the shear efficiency and dispersion uniformity of the dispersion mechanism 300.

[0083] It should be noted that the term "slot ratio" refers to the ratio of the slot length to the product length along the length direction of the product. For example, in this embodiment, the slot ratio of the first shear channels 131 of the stator ring 33 refers to the ratio of the sum of the widths of all first shear channels 131 along the circumferential direction Z of the pulping apparatus 1000 to the circumference of the stator ring 33 along the circumferential direction Z of the pulping apparatus 1000.

[0084] In some embodiments, the slot ratio of the first shear channel 131 is less than or equal to 0.8. It is understood that when the slot ratio of the first shear channel 131 is too large, the contact area between the rotor 10 and the slurry is also increased, thereby enhancing the shear strength of the rotor ring 13. However, an excessively large slot ratio of the rotor 10 slots can easily lead to uneven shear force distribution. Excessive shear force may damage the structure of various materials in the slurry in some areas, while insufficient shear force may prevent other areas from achieving the desired dispersion effect. Furthermore, because the rotor 10 requires more energy to overcome the greater shear resistance, the energy consumption and maintenance cost of the dispersion mechanism 300 are increased. In the embodiment of the present invention, the slot ratio of the first shear channel 131 is set between 0.2 and 0.8. On the one hand, the shear efficiency and dispersion uniformity of the dispersion mechanism 300 are improved, while the energy consumption and maintenance cost of the dispersion mechanism 300 are reduced; on the other hand, the slurry can effectively reduce the viscosity of the slurry under the action of a higher shear force, thereby accelerating the transmission speed of the slurry, making the slurry easier to flow, improving the discharge capacity of the dispersion mechanism 300, and promoting the reciprocating circulation of the slurry.

[0085] For example, the slot ratio of the first shear channel 131 may also be, but is not limited to, 0.3, 0.4, 0.5, 0.6, or 0.7, etc. It should be noted that the slot ratio of the first shear channel 131 can be set according to factors such as the size parameters of the pulping tank 100, the volume and viscosity of the slurry to be dispersed, and is not specifically limited in the embodiment of the present invention.

[0086] The shear channel 301 provided on the stator ring 33 is defined as a second shear channel 331. Specifically, the stator ring 33 is provided with a plurality of second shear channels 331 along the circumferential direction Z of the dispersion mechanism 300. The plurality of second shear channels 331 are arranged at intervals. In this embodiment, the first shear channel 131 and the second shear channel 331 are configured as closed-loop grooves. In some embodiments, the first shear channel 131 and the second shear channel 331 can also be configured as open-loop grooves. Rounded corners are provided at the corners of the first shear channel 131 and the second shear channel 331. As a result, the structural strength of the rotor ring 13 and the stator ring 33 is improved, stress concentration is prevented, the service life is extended, and the aesthetics is improved.

[0087] In this embodiment, the stator base 31 is located at the top of the rotor base 11. The stator base 31 is provided with a through hole 311, which is connected to the multiple first shear channels 131 and the circulation chamber 101. Therefore, when the dispersion mechanism 300 is installed in the pulping tank, the slurry in the pulping tank is introduced into the interior of the dispersion mechanism 300 through the through hole 311, thereby realizing the shear dispersion treatment of the slurry by the rotor ring 13 and the stator ring 33, thereby improving the shear dispersion effect. Of course, in some embodiments, the stator base 31 can also be located at the bottom of the rotor base 11. The rotor base 11 is provided with a through hole 311. The through hole 311 is connected to the multiple second shear channels 331 and the circulation chamber 101.

[0088] In some embodiments, the stator base 31 and the inner wall of the pulping tank form a dispersion chamber 302; alternatively, the stator 30 further includes a connecting base 35, and the stator base 31 and the connecting base 35 are connected to form the dispersion chamber 302. The dispersion chamber 302 is connected to the circulation chamber 101 of the pulping tank 100 via a through hole 311. The rotor 10 is rotatably disposed within the dispersion chamber 302. Thus, based on the connection between the stator base 31 and the connecting base 35 to form the dispersion chamber 302, the majority of the slurry in the dispersion chamber 302 is sheared by the rotor ring 13 and the stator ring 33 before being discharged from the dispersion mechanism 300. This prevents the slurry in the dispersion chamber 302 from leaking into the inner cavity of the pulping tank 100 without being sheared by the rotor ring 13 and the stator ring 33. Furthermore, the impact of slurry outside the dispersion mechanism 300 on the internal structure of the dispersion mechanism 300 is weakened, thereby reducing energy loss of the fluid within the dispersion mechanism 300 and improving the circulation and dispersion capabilities of the dispersion mechanism 300. The connecting base 35 is sealedly connected to the pulping tank 100. This improves the stability and reliability of the connection between the stator base 31 and the inner wall of the bottom of the pulping tank 100. On the other hand, the stator base 31 and the connecting base 35 can guide the slurry in the radial direction Y of the pulping tank 100, so that most of the slurry thrown out by the dispersion mechanism 300 flows toward the inner wall of the pulping tank 100 and flows along the inner wall of the pulping tank 100, extending the circulation path, preventing the slurry discharged from the dispersion mechanism 300 from quickly returning to the through hole 311, improving the circulation capacity, and enhancing the dispersion and mixing effects of the slurry.

[0089] In some embodiments, a shear gap 303 is formed between adjacent rotor rings 13 and stator rings 33 in the radial direction Y of the pulping apparatus 1000, and the shear gap 303 is less than or equal to 5 mm. It is understandable that when the shear gap 303 is too large, the range and intensity of the shear force will be correspondingly weakened, thereby reducing the time and intensity of the shear force acting on the slurry, resulting in a reduction in the shear dispersion effect on the slurry. In the embodiment of the present invention, the shear gap 303 is set to be less than or equal to 5 mm, so that the shear gap 303 is small, prompting the various materials in the slurry to be effectively broken and dispersed by sufficient shear force and pressure, thereby improving the dispersion uniformity of the slurry and enhancing the dispersion efficiency and dispersion effect of the dispersion mechanism 300 on the slurry. At the same time, the slurry can effectively reduce the viscosity of the slurry under higher shear force and pressure, thereby accelerating the transmission speed of the slurry, making the slurry easier to flow, improving the discharge capacity of the dispersion mechanism 300, and promoting the reciprocating circulation of the slurry.

[0090] Optionally, the shear gap 303 is less than or equal to 2 mm, so that when the slurry passes through the narrow shear gap 303, it will be subjected to greater shear force, friction force, and impact force, which will promote the breakage and deagglomeration of particles in the slurry, and increase the contact area and contact time between the slurry and the surface of the dispersion mechanism 300, thereby improving the shear dispersion of the slurry. It should be noted that the shear gap 303 can be set according to factors such as the size parameters of the pulping tank 100, the volume and viscosity of the slurry to be dispersed, and is not specifically limited in the embodiment of the present invention. For example, the shear gap 303 can also be less than or equal to 4 mm, 3 mm, or 1 mm.

[0091] In some embodiments, in the radial direction Y of the pulping apparatus 1000, a shear gap 303 is formed between adjacent rotor rings 13 and stator rings 33, and the ratio of the volume of the shear gap 303 to the circulation flow of the shear gap 303 is greater than or equal to 1ms. It can be understood that when the ratio of the volume of the shear gap 303 to the circulation flow of the shear gap 303 is small, the shearing effect generated by the dispersion mechanism 300 may not be strong enough, which may lead to uneven dispersion of the slurry and easy aggregation or precipitation of particles. The embodiment of the present invention sets the ratio of the volume of the shear gap 303 to the circulation flow of the shear gap 303 to be greater than or equal to 1ms, so that the shearing effect generated by the dispersion mechanism 300 is more concentrated, thereby providing a greater shear force to the slurry, helping to better disperse the particles or solids in the slurry in the liquid material, preventing the slurry from aggregating or settling particles, thereby improving the overall uniformity and stability of the slurry, and at the same time improving the discharge capacity of the dispersion mechanism 300 and promoting the reciprocating circulation of the slurry. Optionally, the ratio of the volume of the shear gap 303 to the circulation flow of the shear gap 303 is greater than or equal to 10 ms.

[0092] Of course, in some embodiments, the ratio of the volume of the shear gap 303 to the circulation flow of the shear gap 303 can be set according to the size parameters of the pulping tank 100, the volume of the slurry to be dispersed, the viscosity and other factors. The embodiments of the present utility model do not make specific limitations. For example, the ratio of the volume of the shear gap 303 to the circulation flow of the shear gap 303 can also be greater than or equal to 3ms, 5ms, 7ms, 9ms, 11ms, 13ms, 15ms or 17ms, etc. The embodiments of the present utility model do not make specific limitations.

[0093] In some embodiments, the linear velocity of the rotor 10 is between 10 m / s and 30 m / s. It is understood that when the linear velocity of the rotor 10 is too high, the particles in the slurry may be subjected to excessive shear forces, which may damage the particle structure and result in particles being too small, thereby affecting the dispersion stability of the slurry. Furthermore, it may cause significant wear on the dispersion mechanism 300, increase the energy consumption of the equipment, and reduce the energy efficiency ratio. When the linear velocity of the rotor 10 is too low, the shear forces applied to the slurry in the gap between the stator 30 and the rotor 10 are relatively low, which may result in insufficient dispersion of the various materials in the slurry, thereby affecting the uniformity and stability of the slurry, as well as affecting the transmission speed of the slurry within the dispersion mechanism 300. The embodiment of the present invention sets the linear velocity of the rotor 10 to 10m / s-30m / s, so that the rotor 10 can provide an appropriate rotational speed, ensuring that the shear force generated by the rotor 10 can break large particles in the slurry into small particles, thereby achieving fine dispersion of the slurry, thereby improving the dispersion efficiency and uniformity of the slurry by the dispersion mechanism 300, improving the quality of the slurry, and reducing the wear and energy consumption of the dispersion mechanism 300; on the other hand, the slurry can effectively reduce the viscosity of the slurry under a higher shear force, thereby accelerating the transmission speed of the slurry, making the slurry easier to flow, improving the discharge capacity of the dispersion mechanism 300, and promoting the reciprocating circulation of the slurry.

[0094] Of course, in some embodiments, the linear speed of the rotor 10 can be set according to the size parameters of the pulping tank 100, the volume of the slurry to be dispersed, the viscosity and other factors, and the embodiments of the present invention do not make specific limitations. For example, the linear speed of the rotor 10 can be greater than or equal to 10m / s, 15m / s, 20m / s, 25m / s or 30m / s, etc., and the embodiments of the present invention do not make specific limitations.

[0095] In some embodiments, the ratio of the effective volume of the pulping tank 100 to the circulation flow rate of the pulping tank 100 is less than or equal to 2 min. It can be understood that when the ratio of the effective volume of the pulping tank 100 to the circulation flow rate of the pulping tank 100 is too large, the slurry stays in the pulping tank 100 for too long, allowing the components in the slurry to have time to undergo unnecessary precipitation and separation, thereby affecting the uniformity of the slurry and reducing production efficiency. The ratio of the effective volume of the pulping tank 100 to the circulation flow rate of the pulping tank 100 is less than or equal to 2 min, thereby increasing the circulation speed of the slurry in the pulping tank 100, reducing the precipitation, stratification, agglomeration and other problems caused by the long-term residence of the slurry, improving the uniformity of the slurry, and improving the production efficiency of the slurry. Optionally, the ratio of the effective volume of the pulping tank 100 to the circulation flow rate of the pulping tank 100 is less than or equal to 1 min.

[0096] It should be noted that the effective volume of the pulping tank 100 refers to the maximum volume of slurry that the pulping tank 100 can accommodate under normal operating conditions. The circulation flow rate of the pulping tank 100 refers to the volume of fluid flowing through the pulping tank 100 per unit time during the circulation process. The ratio of the effective volume of the pulping tank 100 to the circulation flow rate of the pulping tank 100 is for illustrative purposes only and can be set based on factors such as the viscosity and volatility of the slurry to be dispersed. This is not specifically limited in the present embodiment.

[0097] The angle formed by the slotting direction of the first shearing channel 131 and the rotation direction F of the rotor 10 is a first angle, which is recorded as α. The angle formed by the slotting direction of the second shearing channel 331 and the rotation direction F of the rotor 10 is a second angle, which is recorded as β, wherein 90°≤α<180°, 0°<β≤90°. Therefore, when the slotting direction of the first shear channel 131 is opposite to the rotation direction F of the rotor 10, and the slotting direction of the second shear channel 331 is the same as the rotation direction F of the rotor 10, the flow path of the slurry in the first shear channel 131 will change, so that the rotor 10 can generate stronger shear force and turbulence, thereby helping to disperse and mix the various materials in the slurry; on the other hand, when the slotting direction of the first shear channel 131 and the slotting direction of the second shear channel 331 are opposite, the kinetic energy loss of the slurry when passing through the stator ring 33 and the rotor ring 13 is reduced; on the other hand, when the slotting directions of the first shear channel 131 and the second shear channel 331 are the same, it can better match the movement of the rotor 10 and the stator 30, form a more effective shear force, and promote the dispersion and mixing of particles.

[0098] Optionally, 110°≤α≤160°, 20°≤β≤70°. Based on the opposite inclination directions of the first shear channel 131 and the second shear channel 331, on the one hand, the shearing effect of the slurry during high-speed rotation is increased, thereby effectively breaking the aggregation between the particles and promoting more uniform dispersion; on the other hand, the distribution of the flow field is improved, the unevenness of the slurry during the dispersion process is avoided, and each particle is ensured to be effectively dispersed; on the other hand, the shear dispersion of the slurry is improved, the dispersion time is reduced, and the pulping efficiency is improved; on the other hand, after the slurry is dispersed through the shear area between the stator ring 33 and the rotor ring 13, it still has sufficient kinetic energy to be discharged by centrifugation, and there is no need to add discharge blades on the outside of the outermost stator ring 33 to work on the slurry, which greatly reduces the disturbance of the fluid in the discharge area, so that the slurry pressure in the discharge area can be kept uniform and stable, the fluid can be discharged at a stable flow rate, and the vibration and noise caused by pulsation are eliminated.

[0099] Of course, in some embodiments, such as Figure 2-Figure 5 As shown, in the second embodiment, the slotting direction of the first shearing channel 131 and the slotting direction of the second shearing channel 331 may also be the same as the rotation direction F of the rotor 10, which is not specifically limited in the present invention.

[0100] In some embodiments, the stator 30 is entirely configured as a metal structure. Metal structures include, but are not limited to, carbon steel, stainless steel, and metal alloys. Stainless steel has excellent corrosion resistance and high temperature resistance. Carbon steel is relatively low in cost and has good mechanical properties. Metal alloys have excellent wear resistance and corrosion resistance.

[0101] In other embodiments, the stator 30 can be entirely constructed of plastic; or, the stator 30 can be constructed of metal with the surface of the stator 30 covered with a plastic structure. This can be achieved by using a low-cost plastic material, which reduces costs. Furthermore, the plastic structure can deform under external forces, increasing the contact area between the slurry and the stator 30 and improving the shearing effect.

[0102] When the stator 30 is entirely configured as a plastic structure or the surface of the stator 30 is coated with a plastic structure, the first angle ranges from 85 degrees to 95 degrees, i.e., 85° ≤ α ≤ 95°. The second angle also ranges from 85 degrees to 95 degrees, i.e., 85° ≤ α ≤ 95°. It is understood that when the slotting directions of the first shearing channel 131 and the second shearing channel 331 are tilted relative to the radial direction Y of the dispersion mechanism 300, the sharp angles formed by the edges of the first shearing channel 131 and the second shearing channel 331 are prone to deformation, thereby affecting the shear dispersion effect. The present invention is based on setting appropriate first and second angles so that the sharp angles formed by the edges of the first shearing channel 131 and the second shearing channel 331 are approximately right angles, thereby preventing deformation of the edges of the first shearing channel 131 and the second shearing channel 331 and improving the shear effect and efficiency of the stator 30 and the rotor 10. Optionally, in some embodiments, α = 90° and β = 90°.

[0103] For example, in this embodiment, one rotor ring 13 is provided, and two stator rings 33 are provided. The rotor ring 13 is provided between the two stator rings 33. Thus, on the one hand, by providing the rotor ring 13 between the two stator rings 33, the slurry can form a better circulation and turbulent flow zone in the slurry tank, thereby improving the dispersion efficiency; on the other hand, the stator ring 33 can optimize the flow path and velocity distribution of the slurry fluid, making the slurry fluid more uniform during the dispersion process, reducing the phenomenon of slurry swirling due to uneven velocity, reducing the depth of the vortex, and improving the circulation effect of the slurry; on the other hand, the overall structure of the rotor 10 and the stator 30 is simplified, and at the same time, shear force and impact force are generated through the interaction between the rotor 10 and the stator 30, thereby achieving dispersion and mixing of the slurry.

[0104] Of course, in some embodiments, two rotor rings 13 are provided and three stator rings 33 are provided. Along the radial direction Y of the dispersion mechanism 300, each rotor ring 13 is provided between two adjacent stator rings 33. Thus, on the one hand, by providing an appropriate number of rotor rings 13 and stator rings 33, a stronger shear force and a larger impact area can be provided, the range of action of the shear force and friction force can be increased, and more efficient slurry dispersion and mixing can be achieved, thereby improving the dispersion effect and dispersion efficiency of the dispersion mechanism 300 and improving the quality of the slurry; on the other hand, by providing each rotor ring 13 between two adjacent stator rings 33, the flow path and velocity distribution of the slurry fluid can be optimized, making the fluid more uniform during the dispersion process, reducing the phenomenon of slurry swirling due to uneven velocity, reducing the depth of the vortex, and improving the circulation effect of the slurry.

[0105] It should be noted that the number of rotor rings 13 and stator rings 33 is for illustrative purposes only. The number of rotor rings 13 and stator rings 33 can be adjusted based on factors such as the size of the slurry tank 100, the volume and viscosity of the slurry to be dispersed, and is not specifically limited in the present embodiment. For example, in some embodiments, there is one rotor ring 13 and one stator ring 33. The stator ring 33 can be located outside the rotor ring 13; alternatively, the stator ring 33 can be located inside the rotor ring 13.

[0106] The rotor ring 13 is provided in plurality, and the first shear channels 131 of two adjacent rotor rings 13 are staggered along the radial direction Y of the pulping equipment 1000; and / or the stator ring 33 is provided in plurality, and the second shear channels 331 of two adjacent stator rings 33 are staggered along the radial direction Y of the pulping equipment 1000. Thus, due to the staggered arrangement of the first shear channels 131 of two adjacent rotor rings 13 or the second shear channels 331 of two adjacent stator rings 33, on the one hand, the shear dead zone is reduced, ensuring that the slurry can be effectively sheared throughout the shear flow channel of the dispersion mechanism 300, thereby improving the dispersion uniformity of the slurry; on the other hand, when the fluid flows between the stator 30 and the rotor 10, it is subjected to a high degree of shearing, is broken and dispersed, and is continuously redistributed, extending the shear path, which can effectively increase the shear area, thereby enhancing the shear force, and further improving the shear dispersion effect.

[0107] In this embodiment, multiple stator rings 33 are provided, and the thickness of the multiple stator rings 33 gradually increases from the inside out. Therefore, on the one hand, because the centrifugal force exerted on the slurry by the rotor 10 during high-speed rotation gradually increases from the inside out, the present invention provides multiple stator rings 33 with gradually increasing thickness from the inside out, thereby gradually increasing the structural strength of the stator rings 33 from the inside out, preventing deformation of the outer stator rings 33 and improving the shearing and dispersion effects of the dispersion mechanism 300.

[0108] Along the radial direction Y of the dispersion mechanism 300, the rotor ring 13 and the stator ring 33 are alternately arranged at equal intervals; the width of the first shear channel 131 in the circumferential direction Z of the dispersion mechanism 300 is greater than or equal to the width of the second shear channel 331 in the circumferential direction Z of the dispersion mechanism 300. Therefore, on the one hand, based on the arrangement of the rotor ring 13 and the stator ring 33 being alternately arranged at equal intervals so as to make the shear gap 303 consistent, the shear force on the slurry during the dispersion process is uniform, so that the slurry can be dispersed more evenly inside the dispersion mechanism 300, reducing the unevenness of the slurry during the dispersion process, thereby improving the quality of the slurry, and making the relative area between the rotor ring 13 and the stator ring 33 larger, increasing the relative shear volume, and improving the dispersion effect of the dispersion mechanism 300; on the other hand, based on the arrangement of the first shear channel 131 in the dispersion mechanism 300, the shear gap 303 is kept consistent, so that the shear force on the slurry during the dispersion process is uniform, thereby reducing the unevenness of the slurry during the dispersion process, thereby improving the quality of the slurry, and making the relative area between the rotor ring 13 and the stator ring 33 larger, increasing the relative shear volume, and improving the dispersion effect of the dispersion mechanism 300. The width of the dispersion mechanism 300 in the circumferential direction Z is equal to the width of the second shear channel 331 in the circumferential direction Z of the dispersion mechanism 300, so that the shear force and friction force to which the slurry is subjected when passing through the first shear channel 131 and the second shear channel 331 are relatively uniform, reducing the unevenness of the slurry during the dispersion process, thereby improving the quality of the slurry; when the width of the first shear channel 131 in the circumferential direction Z of the dispersion mechanism 300 is greater than the width of the second shear channel 331 in the circumferential direction Z of the dispersion mechanism 300, it is possible to reduce excessive shearing of the material by the rotor 10.

[0109] It should be noted that the term "equal" as used herein may include situations where the shear gaps 303 are approximately equal due to processing errors, measurement errors, etc. For example, "the shear gaps 303 remain consistent in the radial direction Y of the dispersion mechanism 300" may include situations where any two shear gaps 303 are identical in the radial direction Y of the dispersion mechanism 300, and also includes situations where any two shear gaps 303 are approximately identical in the radial direction Y of the dispersion mechanism 300. "the width of the first shear channel 131 is equal to the width of the second shear channel 331" may also include situations where the width of the first shear channel 131 is approximately the same as the width of the second shear channel 331.

[0110] For example, in this embodiment, the impeller 12 is configured as a conical structure. Along the radial direction Y of the pulping equipment 1000, the radial dimension of the impeller 12 gradually increases from the suction end toward the discharge end. As a result, the slurry can flow from the suction end of the impeller 12 to the discharge end of the impeller 12. Since the radial dimension of the impeller 12 gradually increases from the suction end toward the discharge end, the flow rate of the slurry gradually increases, while the pressure gradually decreases, reducing capacity loss. On the other hand, the conical impeller 12 can more effectively convert the kinetic energy of the fluid into pressure energy, thereby improving the suction and discharge capabilities of the dispersion mechanism 300. On the other hand, the conical impeller 12 makes the fluid flow more stable, reduces eddies and turbulence, and thus reduces mechanical vibration and fluid dynamic noise.

[0111] The inner sidewall of the shear channel 301 is provided with a shear structure 304. Thus, the shear structure 304 is used to provide shearing and breaking forces to the slurry when the rotor 10 rotates relative to the stator 300, 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 shear structure 304 can be recessed into the inner sidewall of the shear channel 301; alternatively, it can be protruded from the inner sidewall of the shear channel 301. One or more shear structures 304 can be provided. The shear structure 304 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 304 is streamlined, thereby reducing the flow resistance of the slurry, increasing the flow rate of the slurry, and reducing the amount of slurry remaining on the sidewalls of the rotor 10 or stator 30.

[0112] Optionally, in this embodiment, the shear structure 304 is integrally formed with the rotor 10 or the stator 30 to increase the structural stability of the shear structure 304 and the rotor 10 or the stator 30, thereby improving the dispersion stability of the dispersion mechanism 300. Of course, in some embodiments, the shear structure 304 and the rotor 10 or the stator 30 are detachably connected to each other, so that the shear structure 304 can be installed in different areas of the rotor 10 or the stator 30 according to actual needs.

[0113] The rotor ring 13 and the impeller 12 are disposed on the same side of the rotor base 11, thereby facilitating the processing and manufacturing of the rotor 10. Specifically, the rotor ring 13 is disposed around the bottom of the impeller 12, thereby making the overall structure of the dispersion mechanism 300 rational and compact. Of course, in some embodiments, the impeller 12 can be disposed on both sides of the rotor base 11 in the axial direction X of the circulating pulping apparatus 1000. The rotor ring 13 can be disposed on both sides of the rotor base 11 in the axial direction X of the circulating pulping apparatus 1000.

[0114] The impeller 12 includes a suction end and a discharge end that are relatively arranged. The radial dimension of the impeller 12 at the suction end is smaller than the radial dimension of the impeller 12 at the discharge end. Specifically, the impeller 12 is configured as a conical structure. Along the radial direction Y of the circulating pulping equipment 1000, the radial dimension of the impeller 12 gradually increases from the suction end toward the discharge end. As a result, the slurry can flow from the suction end of the impeller 12 to the discharge end of the impeller 12. Since the radial dimension of the impeller 12 gradually increases from the suction end toward the discharge end, the flow rate of the slurry gradually increases, while the pressure gradually decreases, reducing capacity loss; on the other hand, the conical impeller 12 can more effectively convert the kinetic energy of the fluid into pressure energy, thereby improving the suction capacity and discharge capacity of the dispersion mechanism 300; on another hand, the conical impeller 12 makes the fluid flow smoother, reduces eddies and turbulence, and thus reduces mechanical vibration and fluid dynamic noise.

[0115] The impeller 12 includes a base 121 and blades 122. The base 121 is fixedly connected to the rotor base 11, and the blades 122 are arranged on the side walls of the base 121. The blades 122 are configured as, but not limited to, straight blades, cylindrical blades, or twisted blades. Therefore, on the one hand, when the blades 122 are configured as straight blades or cylindrical blades, the processing and manufacturing of the impeller 12 are simplified, and cleaning is facilitated; on the other hand, when the blades 122 are configured as twisted blades, they can better adapt to the flow characteristics of the slurry, reduce the rotation loss of the slurry fluid when passing through the blades 122, improve the slurry conveying efficiency, and the twisted blades make the slurry fluid pass through the impeller 12 more evenly, reduce the impact and expulsion of the slurry fluid, and further reduce the vibration and noise of the dispersion mechanism.

[0116] It should be noted that a cylindrical blade refers to a structure in which the surface of blade 122 is unidirectionally curved. A cylindrical blade is also referred to as a single-curvature blade or an oblique blade. Specifically, within a projection plane perpendicular to the central axis of base 121, the cylindrical blade is curved relative to the radial direction of base 121. 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 blade 122 is bidirectionally curved. A cylindrical blade is also referred to as a spatially curved surface or a double-curvature blade.

[0117] Specifically, in this embodiment, the base 121 is configured as a truncated cone structure, and the blades 122 are configured as twisted blades. Thus, on the one hand, the slurry can be continuously separated in the three-dimensional space of the impeller 12, reducing energy loss during slurry flow and improving the slurry conveying efficiency of the impeller 12; on the other hand, it avoids the occurrence of cavitation and reduces noise. The cross-section of the base 121 along the radial direction Y of the pulping equipment 1000 gradually increases from the suction end toward the discharge end. The side wall of the base 121 is configured as a curved surface. The meridian flow line of the base 121 from the suction end to the discharge end is a curve that bends inward relative to the central axis P of the base 121. The meridian flow line is roughly arc-shaped.

[0118] In some embodiments, the base 121 is configured as a cylinder, and the blades 122 are configured as cylindrical blades. This facilitates the processing and manufacturing of the impeller 12, facilitates cleaning, and improves the operational stability of the impeller 12. The cross-section of the base 121 along the radial direction Y of the pulping apparatus 1000 remains constant from the suction end to the discharge end. The sidewalls of the base 121 are configured as cylindrical surfaces. The meridian flow line of the base 121 from the suction end to the discharge end is parallel to the central axis P of the base 121. For another example, the base 121 can also be configured as a truncated cone, and the blades 122 can be configured as cylindrical blades.

[0119] In other embodiments, blades 122 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's height, and the line connecting the centroids of its cross section aligns with the radial direction of the impeller 12. Specifically, within a projection plane perpendicular to the central axis of the base 121, the blades 122 extend from the inside outward in the radial direction of the impeller 12. For example, in some embodiments, within a projection plane parallel to the central axis of the base 121, the extension direction of the linear blades may be parallel to the central axis of the base 121. In other embodiments, within a projection plane parallel to the central axis of the base 121, the extension direction of the linear blades may intersect the central axis of the base 121. In other words, within a projection plane parallel to the central axis of the base 121, the extension direction of the linear blades may be arranged at an angle to the central axis of the base 121. Blades 122 may also employ other centrifugal blade structures, which are not specifically limited in this embodiment.
