[0029] 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.

[0030] See also Figure 1 , Figure 1It is a cross-sectional view of the circulating pulping equipment 1000 provided in an embodiment of the present invention. The pulping equipment 1000 includes a circulation tank 100 and a dispersion mechanism 300. The dispersion mechanism 300 is arranged in the circulation tank 100 and is used to disperse the slurry. For example, in this embodiment, the circulation tank 100 is provided with a circulation chamber 101. The dispersion mechanism 300 is arranged at the bottom of the circulation tank 100 and is located in the circulation chamber 101. The circulation chamber 101 is used to accommodate the slurry to be dispersed. The slurry may 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, liquid materials or powder materials, etc. Various materials are mixed to form battery slurry. Powder materials include but are not limited to active substances, conductive agent powders, binder powders and other powder materials. Liquid materials include but are not limited to liquids such as conductive agent solutions and binder solutions. Liquid materials can also include liquids obtained by mixing powder materials and liquid materials. In this embodiment, the slurry is illustrated as battery slurry. It can be understood that the dispersion mechanism 300 can also be used to disperse other slurries, such as food, medicine, fertilizer, building materials, etc., and the application of the dispersion mechanism 300 is not limited here.

[0031] In this embodiment, the circulation 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, and tilting of the various components of the circulating pulping apparatus 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 circulation tank 100 and the dispersion mechanism 300, resulting in a rational layout and compact structure. It also facilitates cleaning and maintenance of the components of the circulating pulping apparatus 1000.

[0032] It is understandable that when using the circulating pulping equipment 1000 for pulping, liquid can be added to the circulation tank 100 first, and the liquid can be pre-dispersed by the dispersion mechanism 300 before the powder is added, thereby improving the wetting effect of the liquid on the powder and improving the dispersion and mixing effect of the dispersion mechanism 300; alternatively, liquid can be added to the circulation tank 100 first, and then the powder is added, and after the powder and liquid are added, the dispersion mechanism 300 is started to disperse, so as to achieve a cyclic reciprocating motion of the slurry in the circulation tank 100. The circulation tank 100 is provided with a discharge pipe 103 to realize the discharge of the slurry. Optionally, the discharge pipe 103 is provided at the bottom of the circulation tank 100. The discharge pipe 103 is arranged to be tilted downward relative to the central axis P of the circulation tank 100, thereby improving the discharge effect.

[0033] In some embodiments, the circulating slurrying apparatus 1000 further includes a powder conveying mechanism. This mechanism can be located on the tank body 110 or on the tank lid 120. The powder conveying mechanism can include, but is not limited to, a feed screw or a rotary valve, thereby achieving uniform feeding and improving slurry mixing uniformity. In some embodiments, a powder dispersing mechanism is provided within the powder conveying mechanism's transmission path to enhance the wetting effect of the liquid on the powder, reduce wear on the dispersion mechanism 300, and thereby improve the dispersion efficiency of the dispersion mechanism 300.

[0034] The circulating pulping apparatus 1000 also includes a liquid material conveying mechanism. This mechanism is located on the tank body 110 or the tank cover 120. Optionally, a guide mechanism is provided along the liquid material conveying mechanism's transmission path. This guide mechanism is used to direct the liquid material to a designated location within the circulating tank 100. For example, the guide mechanism can direct the slurry 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.

[0035] It should be noted that Figure 1 The purpose is only to schematically describe the arrangement between the circulation tank 100 and the dispersion mechanism 300, and is not to make specific limitations on the connection position, connection relationship and specific structure of each component. Figure 1 The structure of the dispersion mechanism 300 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 dispersion mechanism 300 may include Figure 1 More or fewer components, or combinations of certain components, or different components, such as the dispersion mechanism 300 may also include but not limited to a driver, etc. The driver is used to drive the dispersion mechanism 300 to disperse the slurry.

[0036] Please also refer to Figures 1 to 3 , Figure 2 yes Figure 1 A schematic structural diagram of the dispersion mechanism 300 of the circulating pulping equipment 1000; Figure 3 yes Figure 2sectional view of the dispersion mechanism 300 of the circulating pulping equipment 1000 in FIG. The dispersion mechanism 300 includes a stator 30 and a rotor 10. The rotor 10 includes a rotor base 11 and at least one rotor ring 13. Each rotor ring 13 is arranged on the top wall of the rotor base 11, and a plurality of rotor slots 131 are arranged along the circumferential direction Z of the dispersion mechanism 300. The stator 30 includes a stator base 31, at least one stator ring 33 and a guide plate 34. A through hole 3101 connected to the inner cavity of the circulation tank 100 is provided in the middle part of the stator base 31. Each stator ring 33 is provided on the bottom wall of the stator base 31, and is alternately arranged with the rotor ring 13 along the radial direction Y of the dispersion mechanism 300. The stator ring 33 is provided with a plurality of stator slots 331 connected to the through hole 3101 and the plurality of rotor slots 131 along the circumferential direction Z of the dispersion mechanism 300. The guide plate 34 is disposed at the outer edge of the stator base 31 and is tilted outward relative to the stator base 31 toward a side away from the stator ring 33 .

[0037] It can be understood that when the rotor 10 of the dispersion mechanism 300 rotates at high speed, negative pressure is generated. Under the action of the negative pressure, part of the slurry above the dispersion mechanism 300 is sucked into the interior of the dispersion mechanism 300 through the through hole 3101 and is sheared and dispersed by the stator 30 and the rotor 10. Another part of the slurry above the dispersion mechanism 300 acts on the top wall of the stator base 31 and flows to the guide plate 34. The dispersion mechanism 300 provided by the embodiment of the present invention, on the one hand, is based on the fact that a guide plate 34 is provided on the outer edge of the stator base 31, and the guide plate 34 is inclined outward relative to the stator base 31 toward the side away from the stator ring 33, so that the setting of the guide plate 34 can drain the slurry, prompting the slurry to flow upward toward the side wall of the circulation tank 100, thereby achieving better up and down flipping of the slurry in the circulation tank 100, thereby improving the circulation capacity of the slurry and improving the mixing and dispersion effect of the dispersion mechanism 300 on the slurry; on the other hand, the stator base 31 is set above the rotor base 11, so that the stator base 31 cooperates with the inner wall of the bottom of the circulation tank 100 to generate a force similar to that of a centrifugal pump, thereby increasing the rate at which the slurry passes through the rotor ring 13 and the stator ring 33, and avoiding the problem of the slurry leaking to the outside of the dispersion mechanism 300 without being sheared by the stator ring 33 and the rotor ring 13, thereby improving the dispersion effect and dispersion efficiency.

[0038] 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 dispersion mechanism 300, 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 dispersion mechanism 300, that is, the radial direction along the cross section of the dispersion mechanism 300, 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 dispersion mechanism 300, that is, the direction surrounding the central axis P of the dispersion mechanism 300, wherein the axial direction X, radial direction Y and circumferential direction Z together 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 according to the specific structure of the product and the perspective of the drawings, and this utility model does not make specific limitations. 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 limitations on implementation.

[0039] It should be noted that the term "outer edge" refers to the outer boundary of the stator base 31. In an embodiment of the present invention, the outer edge of the stator base 31 may include the outer edge of the stator base 31, and may also include the portion of the stator base 31 near the outer edge of the stator base 31. For example, in this embodiment, the guide plate 34 extends from the outer edge of the stator base 31 toward the side wall of the circulation tank 100. Specifically, the guide plate 34 is arranged on the outer wall of the stator base 31 to avoid the formation of a dead angle at the connection between the guide plate 34 and the stator base 31, which would cause part of the slurry to be deposited in the dead angle and unable to participate in the circulation, increasing the difficulty of cleaning the dead angle, and reduce the flow resistance of the slurry, thereby improving the smoothness of the slurry flow. Of course, in some embodiments, the guide plate 34 can also be arranged on the top wall of the stator base 31; or, it can be embedded in the interior of the stator base 31. The arrangement of the guide plate 34 and the stator base 31 can be set according to actual conditions and is not specifically limited by this invention.

[0040] The circulating pulping equipment 1000 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 circulation 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, 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. The circulating pulping equipment 1000 also includes a mounting seat 24, and the driving member 22 is installed on the circulation tank 100 through the mounting seat 24.

[0041] 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 circulating pulping equipment 1000. The connecting end of the limiter 23 is detachably fixedly connected to the rotating shaft 21. 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 stirring shaft 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 the pulping.

[0042] In this embodiment, the guide plate 34 is integrally formed with the stator base 31, thereby improving the reliability and stability of the connection between the guide plate 34 and the stator base 31, improving the stability of the operation of the dispersion mechanism 300, and reducing noise. Of course, in some embodiments, the guide plate 34 is detachably connected to the stator base 31. Thus, on the one hand, it is convenient to install and replace different components to form different configurations, so that the dispersion mechanism 300 can quickly switch configurations to apply different scenarios; on the other hand, it is convenient to perform maintenance, replacement, and other operations on the guide plate 34 and the stator base 31, as well as to facilitate the processing and manufacturing of the guide plate 34 and the stator base 31. The guide plate 34 and the stator base 31 can be detachably connected together by means of screwing, snapping, etc. The guide plate 34 and the stator base 31 can also be non-detachably connected together by means of bonding, welding, etc.

[0043] Specifically, the stator base 31 includes a first base 311 and a second base 312. The second base 312 is disposed on the side of the first base 311 facing away from the rotor base 11 and is fixedly connected to the first base 311. A through hole 3101 extends through both the first and second bases 311, 312. All stator rings 33 are mounted on the first base 311. The guide plate 34 is disposed on the outer edge of the second base 312 and is tilted outward relative to the second base 312, away from the first base 311. Therefore, on the one hand, based on the stator ring 33 being set on the first base 311 and the guide plate 34 being set on the second base 312, the processing and manufacturing of the stator ring 33 and the guide plate 34 are facilitated; on the other hand, the second base 312 can block the impact of the slurry on the first base 311, prevent the stator 30 from deforming, and improve the stability and reliability of the connection between the stator 30 and the circulation tank 100, enhance the working stability of the dispersion mechanism 300, and improve the dispersion effect of the dispersion mechanism 300.

[0044] For example, in this embodiment, the first base 311 and the second base 312 are independently provided. Specifically, the second base 312 is provided with a mounting groove 3121 for mounting the first base 311 on the bottom wall facing the rotor base 11. Thus, on the one hand, the assembly efficiency and connection reliability between the guide member and the stator 30 are improved; on the other hand, the alignment assembly of the stator 30 and the rotor 10 is facilitated, and the structural compactness of the dispersion mechanism 300 is improved. The first base 311 and the second base 312 are fixedly connected together by a locking member 313. The top surface of the locking member 313 can be flush with the top wall of the second base 312, that is, the top surface of the locking member 313 is connected to the top wall of the second base 312 to form a continuous flat surface, thereby improving the smoothness of the slurry flow, promoting the reciprocating circulation of the slurry in the circulation tank 100, improving the circulation capacity of the slurry, and improving the dispersion effect and mixing effect of the slurry. Of course, in some embodiments, the first base 311 and the second base 312 may also be fixedly connected together by means of clamping, welding, bonding, etc., which is not specifically limited in the embodiments of the present utility model.

[0045] In some embodiments, the stator base 31 is configured as a monolithic structure, that is, the first base 311 or the second base 312 can be omitted. Specifically, the first base 311 and the second base 312 can also be integrally formed. Specifically, the guide plate 34 and the stator ring 33 are both directly fixedly connected to the stator base 31.

[0046] In this embodiment, along the radial direction Y of the circulation tank 100 , the distance between the outer edge of the second base 312 and the tank side wall 1013 of the circulation tank 100 is smaller than the distance between the outer edge of the first base 311 and the tank side wall 1013 of the circulation tank 100 . Therefore, on the one hand, the second base 312 can play a guiding role on the slurry in the radial direction of the circulation tank 100, so that most of the slurry thrown out by the dispersion mechanism 300 flows toward the inner wall of the circulation tank 100 and flows along the inner wall of the circulation tank 100, extending the circulation path, avoiding the slurry discharged by the dispersion mechanism 300 from quickly returning to the through hole 3101, improving the circulation capacity, and increasing the surface area of ​​contact between the stator 30 and the slurry, thereby improving the dispersion and mixing effects of the dispersion mechanism 300 on the slurry; on the other hand, the setting of the second base 312 can more flexibly adjust the installation position of the stator 30 and the circulation tank 100, improve the stability and reliability of the connection between the stator 30 and the circulation tank 100, enhance the stability of the dispersion mechanism 300, and reduce noise. Of course, in some embodiments, along the radial direction Y of the circulation tank 100, the distance between the outer edge of the second base 312 and the tank side wall 1013 of the circulation tank 100 may also be equal to or less than the distance between the outer edge of the first base 311 and the tank side wall 1013 of the circulation tank 100.

[0047] The guide plate 34 can be configured as a closed loop structure. For example, the number of guide plates 34 is set to one, and the guide plates 34 are arranged in a circle along the outer edge of the stator base 31. Specifically, the guide plates 34 can be configured as a hollow truncated cone. Of course, in some embodiments, the guide plates 34 can also be configured as an open loop structure. For example, the number of guide plates 34 is set to multiple, and the multiple guide plates 34 are spaced apart and arranged in a circle along the outer edge of the stator base 31. Each guide plate 34 can be configured as a curved plate.

[0048] For example, in this embodiment, the guide plate 34 includes a guide surface 341 connected to the top wall of the stator base 31. The connection between the guide surface 341 and the top wall of the stator base 31 can be set in a circular arc, thereby reducing the flow resistance of the slurry, improving the smoothness of the slurry flow, promoting the reciprocating circulation of the slurry in the circulation tank 100, improving the circulation capacity of the slurry, and improving the dispersion and mixing effects of the slurry. Of course, in some embodiments, the connection between the guide surface 341 and the top wall of the stator base 31 can also be set at a sharp angle to reduce the difficulty of processing and manufacturing. In other embodiments, the guide surface 341 and the top wall of the stator base 31 can also be connected by a transition surface, and the transition surface is inclined relative to the guide surface 341 and the top wall of the stator base 31. The angle formed between the guide surface 341 and the top wall of the stator base 31 is an obtuse angle. Therefore, the included angle formed between the drainage surface 341 and the top wall of the stator base 31 is an obtuse angle, so as to facilitate the slurry to pass through more smoothly, thereby improving the circulation capacity of the slurry.

[0049] Please refer again Figure 2 and Figure 3 In some embodiments, the stator 30 further includes a guide sleeve 35, and the guide sleeve 35 and the stator ring 33 are arranged on different sides of the stator base 31. Specifically, the guide sleeve 35 extends around the edge of the through hole 3101 toward the side facing away from the stator ring 33. Therefore, on the one hand, the guide sleeve 35 can also play a guiding role on the slurry, prompting the slurry discharged from the dispersion mechanism 300 to flip up and down in the circulation tank 100, thereby improving the circulation capacity of the slurry and achieving better dispersion and mixing effects of the slurry; on the other hand, the provision of the guide sleeve 35 can prevent the rotor 10 from being affected by the slurry flow outside the dispersion mechanism 300 when rotating, thereby improving the flow stabilization effect and strengthening the shearing effect of the stator ring 33 and the rotor ring 13 on the slurry.

[0050] The guide sleeve 35 is fixedly connected to the second base 312. In this embodiment, the guide sleeve 35 is integrally formed with the second base 312 and the guide plate 34. Of course, in some embodiments, the guide sleeve 35 can be provided independently of the second base 312. For example, the guide sleeve 35 can be fixedly connected to the second base 312 via a locking mechanism, a clamping mechanism, a welding mechanism, or the like. A guide surface 351 is provided at the bottom of the outer wall of the guide sleeve 35. The guide surface 351 is connected to the outer wall of the guide sleeve 35 and the top wall of the stator 30 seat facing away from the stator ring 33. The guide surface 351 is inclined relative to the central axis P of the guide sleeve 35 and can be flat or curved. Thus, the guide surface 351 can guide the slurry fluid, promoting smooth and stable slurry flow at the corner between the guide sleeve 35 and the stator base 31. This enhances slurry transport and reduces flow resistance, preventing the formation of dead corners that can cause slurry residue and improving slurry circulation. Specifically, the guide sleeve 35 is connected to the top seat of the stator 30 in an arc shape. Therefore, the stator 30 can reduce stress concentration at the corner between the guide sleeve 35 and the top seat of the stator 30 and improve the connection strength between the guide sleeve 35 and the stator base 31.

[0051] In some embodiments, a reinforcement structure 352 is provided on the end surface of the flow guide facing away from the stator base 31. The reinforcement structure 352 is configured as an arc-shaped chamfer or an arc-shaped curling edge. Thus, on the one hand, the provision of the arc-shaped chamfer or arc-shaped curling edge can reduce stress concentration, reduce the force exerted by the fluid slurry on the guide sleeve 35, and improve the reliability and stability of the connection between the stator 30 and the circulation tank 100. On the other hand, the provision of the arc-shaped chamfer or arc-shaped curling edge can also reduce the flow resistance of the slurry, reduce the energy loss of the slurry, improve the transmission efficiency of the slurry, and promote the reciprocating circulation of the slurry.

[0052] In this embodiment, the free end of the guide sleeve 35 is provided with an arc-shaped chamfer. Specifically, the surface of the reinforcement structure 352 is configured as an arc-shaped surface that protrudes outward from the guide sleeve 35. The reinforcement structure 352, along an axial cross-section parallel to the axial direction X of the circulating pulping apparatus 1000, includes a first arc surface 3521 and a second arc surface 3522. The first arc surface 3521 and the second arc surface 3522 are smoothly connected. As a result, the slurry can be quickly guided along the first arc surface 3521 to the outside of the inner cavity of the guide sleeve 35, and can also be quickly guided along the second arc surface 3522 to the inner cavity of the guide sleeve 35.

[0053] Please also refer to Figure 3 and Figure 4 , Figure 4 yes Figure 2 The schematic diagram of the structure of the third embodiment of the circulating pulping equipment 1000 is a diagram in which the guide plate 34 is omitted from the dispersion mechanism 300. It should be noted that, in order to facilitate the description of the structure, Figure 4The guide plate 34 is omitted. Of course, in some embodiments, the guide plate 34 may not be provided on the stator base 31. For example, in this embodiment, the rotor 10 also includes an impeller 12. 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 and discharge capacity of the dispersion mechanism 300; on the other hand, the conical impeller 12 makes the fluid flow smoother, reduces eddies and turbulence, and thus reduces mechanical vibration and fluid dynamic noise.

[0054] The top of the impeller 12 extends into the inner cavity of the guide sleeve 35. The impeller 12 includes a base 121 and blades 122 disposed on the base 121. The diameter of the top of the guide sleeve 35 is smaller than the diameter of the bottom of the guide sleeve 35. The free ends of the blades 122 are disposed close to the inner wall of the guide sleeve 35. Therefore, based on extending the top of the impeller 12 into the inner cavity of the guide sleeve 35, on the one hand, the impeller 12 is prevented from being affected by the external slurry flow of the dispersion mechanism 300 during rotation, the flow stabilization effect is improved, and the shearing effect of the stator ring 33 and the rotor ring 13 on the slurry is strengthened; on the other hand, the guide sleeve 35 can also block the solid matter in the slurry outside the dispersion mechanism 300 from directly colliding with the blades 122, thereby increasing the service life of the impeller 12; on the other hand, based on the fact that the diameter of the top of the guide sleeve 35 is smaller than the diameter of the bottom of the guide sleeve 35, the free end of the blade 122 is arranged close to the inner wall of the guide sleeve 35, so that most of the fluid slurry is pressed into the stator ring 33 and the rotor ring 13 at the bottom through the blade 122 for shearing and dispersion, thereby improving the dispersion uniformity of the slurry.

[0055] Of course, in some embodiments, the top of the impeller 12 can also be located outside the inner cavity of the guide sleeve 35. Thus, on the one hand, the guide sleeve 35 can serve as an inlet for the slurry. In the embodiment of the present application, the impeller 12 is disposed outside the guide sleeve 35, thereby improving the smoothness of the slurry entering the dispersion mechanism 300 and improving the material suction capacity of the dispersion mechanism 300.

[0056] In this embodiment, along the radial direction Y of the circulating pulping equipment 1000, the radial dimension of the guide sleeve 35 gradually increases from the suction end toward the discharge end. On the one hand, the free end of the blade 122 is arranged close to the inner wall of the guide sleeve 35, and then most of the fluid slurry is pressed into the stator ring 33 and the rotor ring 13 at the bottom through the blade 122 for shearing and dispersion, thereby improving the slurry dispersion ability; on the other hand, the guide sleeve 35 is conical or truncated cone-shaped, which can expand the dispersion area of ​​the slurry, reduce the kinetic energy of the slurry input, and prevent the slurry from being unevenly dispersed or the dispersion mechanism 300 from being damaged due to excessive kinetic energy when entering the disperser; on the other hand, it prevents the impeller 12 from colliding with the corner formed at the connection between the guide sleeve 35 and the stator base 31, thereby improving the stability and reliability of the dispersion mechanism 300. Of course, the diameter of the top of the guide sleeve 35 may also be equal to the diameter of the bottom of the guide sleeve 35, that is, the diameter of the guide sleeve 35 may remain unchanged from top to bottom (that is, from the suction end to the discharge end).

[0057] 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 base 121 is configured as a truncated cone structure. The cross-section of the base 121 along the radial direction Y of the circulating 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. The blade 122 is configured as a twisted blade. A twisted blade refers to a blade that is gradually twisted from bottom to top along its own height direction. In this embodiment, a twisted blade refers to a structure in which the surface of the blade is bidirectionally curved. A twisted blade is also called a spatial curved surface or a hyperbolic blade.

[0058] In some embodiments, the radial dimension of the impeller 12 at the suction end is equal to the radial dimension of the impeller 12 at the discharge end. For example, the base 121 is configured as a cylinder. The cross section of the base 121 along the radial direction Y of the circulating pulping equipment 1000 remains unchanged from the suction end to the discharge end. The side wall of the base 121 is configured as a cylindrical surface. 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. The blade 122 is configured as a cylindrical blade. It should be noted that a cylindrical blade refers to a structure in which the cross-sectional shape of the blade remains unchanged. It should be noted that a cylindrical blade refers to a structure in which the surface of the blade is unidirectionally curved. A cylindrical blade is also called a single-curvature blade or an inclined blade. For another example, the base 121 can also be configured as a truncated cone, and the blade 122 is configured as a cylindrical blade.

[0059] 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.

[0060] In this embodiment, the stator 30 further includes a plurality of connecting rods 36. One end of each connecting rod 36 is connected to the stator base 31, and the other end of each connecting rod 36 is connected to the inner wall of the bottom of the circulation tank 100. The connecting rods 36 are arranged at intervals along the circumferential direction Z of the dispersion mechanism 300 and surround the outer side of the outermost stator ring 33. Therefore, on the one hand, based on the setting of the stator base 31, a support connection is achieved with the circulation tank 100 through multiple connecting rods 36. On the other hand, the stator base 31 is set above the rotor base 11, so that the stator base 31 can play a guiding role for part of the slurry outside the dispersion mechanism 300, which is convenient for the slurry to circulate back and forth in the circulation tank 100; on the other hand, the setting of the connecting rod 36 better realizes the transmission and distribution of force, thereby enhancing the stability and carrying capacity of the stator 30 structure, improving the reliability and stability of the connection between the stator 30 of the dispersion structure and the circulation tank 100, and reducing noise; on the other hand, based on the connecting rod 36 arranged around the outermost ring of all stator rings 33, to achieve the shearing effect and drainage function on the slurry, the shearing effect on the slurry is improved, and the overall stability of the dispersion mechanism 300 is enhanced.

[0061] Illustratively, in this embodiment, a plurality of connecting rods 36 are detachably connected to the stator base 31. Specifically, the connecting rod 36 passes through the stator base 31 and is locked to the bottom wall of the bottom of the circulation tank 100. The connecting rod 36 includes a connecting rod portion 361 and a stop portion 362. The stop portion 362 is provided at one end of the connecting rod portion 361. The radial dimension of the stop portion 362 is greater than the radial dimension of the connecting rod portion 361, and the stop portion 362 stops the stator base 31, thereby facilitating the alignment and assembly of the connecting rod 36 and the stator base 31, and preventing the connecting rod 36 from being disconnected from the stator base 31 or the mounting plate.

[0062] In some embodiments, the stator 30 further includes a locking structure. The connecting rod 36 is locked with the locking structure to achieve a fixed connection between the stator base 31 and the circulation tank 100. Specifically, the connecting rod 36 is provided with a threaded hole that cooperates with the locking structure along the axial direction X of the dispersion mechanism 300. The locking structure passes through the bottom wall of the bottom of the circulation tank 100 and is locked in the threaded hole. Thus, on the one hand, a fixed connection between the stator 30 and the circulation tank 100 is achieved, which facilitates installation; on the other hand, the connecting rod 36 can increase the threaded length, thereby improving the reliability of the connection between the dispersion structure and the circulation tank 100. Of course, in some embodiments, the connecting rod 36 is configured as a bolt, and the locking structure is configured as a nut that cooperates with the bolt to facilitate the assembly of the connecting rod 36 and the circulation tank 100. Specifically, the side wall of the end of the connecting rod 36 facing away from the stator base 31 is provided with an external thread, and the nut is provided with an internal thread that matches the external thread of the connecting rod 36. The end of the connecting rod 36 facing away from the stator base 31 passes through the bottom wall of the bottom of the circulation tank 100 and is screwed and fixed to the locking member 313. In other embodiments, a threaded hole is provided inside the connecting rod 36, and an outer wall of the connecting rod 36 is provided with an external thread.

[0063] In some embodiments, multiple connecting rods 36 are integrally formed with the stator base 31. Thus, on the one hand, the integral formation of the connecting rods 36 and the stator base 31 facilitates installation, improves the stability and reliability of the connection between the connecting rods 36 and the stator base 31, enhances the stability of the dispersion mechanism 300, and reduces noise. On the other hand, the connecting rods 36 can also be integrally formed with the stator base 31, thereby facilitating maintenance and replacement of the connecting rods 36 and the stator base 31, as well as facilitating the processing and manufacturing of the connecting rods 36 and the stator base 31.

[0064] For example, in this embodiment, the top surface of the connecting rod 36 is higher than the top wall of the stator base 31. The stopper 362 of the connecting rod 36 extends from the top wall of the stator base 31 and stops there. This facilitates the alignment and assembly of the connecting rod 36 with the stator base 31 and the circulation tank 100. Specifically, the stopper 362 of the connecting rod 36 extends from the top of the second base 312 and stops there.

[0065] In some embodiments, the plurality of connecting rods 36 are located on a side of the stator base 31 close to the rotor base 11. Thus, the plurality of connecting rods 36 are located on a side of the stator base 31 close to the rotor base 11, thereby avoiding the problem of the connecting rods 36 protruding above the stator base 31 and obstructing the flow of the slurry, improving the smoothness of the slurry flow, promoting the reciprocating circulation of the slurry in the circulation tank 100, improving the circulation capacity of the slurry, and improving the dispersion and mixing effects of the slurry.

[0066] A plurality of connecting rods 36 are connected to the bottom wall of the stator base 31. The connecting rods 36 can be directly fixed to the bottom wall of the stator base 31; or, the bottom wall of the stator base 31 is provided with connecting holes for fixing the connecting rods 36, wherein the connecting holes are blind holes. Specifically, the top wall of the stator base 31 is configured as a continuous flat surface. Thus, on the one hand, the completion of the top wall of the stator base 31 is ensured, the problem of material accumulation at the connection between the stator base 31 and the connecting rods 36 is avoided, and cleaning is facilitated; on the other hand, the smoothness of the slurry flow is improved, and the slurry is promoted to perform reciprocating circulation in the circulation tank 100, thereby improving the circulation capacity of the slurry, and improving the dispersion effect and mixing effect of the slurry.

[0067] Of course, in some embodiments, at least a portion of the connecting rod 36 is embedded within the stator base 31, with the top surface of the connecting rod 36 connected to the top wall of the stator base 31 to form a continuous, flat surface. For example, the top wall of the stator base 31 is provided with a countersunk hole, and the stopper 362 of the connecting rod 36 is received within the countersunk hole. This improves the reliability of the connection between the connecting rod 36 and the stator base 31, facilitating positioning and installation. Furthermore, it enhances the smoothness of slurry flow, promotes the reciprocating circulation of the slurry within the circulation tank 100, improves the slurry's circulation capacity, and enhances the dispersion and mixing effects of the slurry.

[0068] The connecting rod portion 361 of the connecting rod 36 can be configured as a cylindrical rod, and the stop portion 362 of the connecting rod 36 can be configured as a prismatic rod. Of course, in some embodiments, the connecting rod 36 can also be configured as a cylindrical rod entirely. The cross-section of the connecting rod 36 along the axial direction X perpendicular to the dispersion mechanism 300 is circular. Therefore, on the one hand, the cylindrical rod ensures uniform force in all directions, ensuring that the connecting rod 36 has a maximum bending moment of inertia against eccentric pressure in all directions, thereby improving the stability and reliability of the connection between the stator 30 and the circulation tank 100; on the other hand, it facilitates processing and manufacturing. Of course, in some embodiments, the connecting rod 36 can be configured as a special-shaped rod. Specifically, the cross-section of the connecting rod 36 along the axial direction X perpendicular to the dispersion mechanism 300 is teardrop-shaped. The teardrop-shaped convex surface of the connecting rod 36 can accelerate the flow rate of the slurry, thereby improving the circulation capacity of the dispersion mechanism 300, promoting reciprocating slurry circulation, and enhancing slurry uniformity. Of course, in some other embodiments, the cross section of the connecting rod 36 along the axial direction X perpendicular to the dispersion mechanism 300 may also be a regular polygon or other regular or irregular shapes, which is not specifically limited in the present invention.

[0069] In some embodiments, a shear structure 363 is provided on the connecting rod 36. Thus, the shear structure 363 is used to provide shearing and breaking forces to the slurry when the rotor 10 rotates relative to the stator 30, 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 363 can be recessed in the sidewall of the connecting rod 36; alternatively, it can be protruded from the sidewall of the connecting rod 36. One or more shear structures 363 can be provided. The shear structure 363 can be configured as, but is not limited to, at least one of a convex point, a concave point, a spiral convex pattern, a spiral concave pattern, an annular convex pattern, or an annular concave pattern. The shear structure 363 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 sidewall of the connecting rod 36.

[0070] Optionally, in this embodiment, the shear structure 363 and the connecting rod 36 are integrally formed to increase the structural stability of the shear structure 363 and the connecting rod 36, thereby improving the dispersion stability of the dispersion mechanism 300. Of course, in some embodiments, the shear structure 363 and the connecting rod 36 are detachably connected, so that the shear structure 363 can be installed in different areas of the connecting rod 36 according to actual needs.

[0071] In some embodiments, a heat dissipation structure is provided on the connecting rod 36. As the rotor 10 of the dispersion mechanism 300 rotates at high speed and rubs against the slurry, a large amount of heat is generated. This heat dissipation structure can dissipate the heat from the slurry to the exterior of the circulation tank 100, improving the efficiency of heat dissipation and the quality of the slurry. The connecting rod 36 can be configured as a heat dissipation structure as a whole; alternatively, the heat dissipation structure can be provided on its surface.

[0072] In some embodiments, the stator 30 also includes a connecting base 38. The connecting base 38 is sealedly connected to the inner wall of the bottom of the circulation tank 100, and is connected to the stator base 31 through a plurality of connecting rods 36 to form a dispersion chamber 301. The rotor 10 is rotatably arranged in the dispersion chamber 301. Thus, on the one hand, the stability and reliability of the connection between the stator base 31 and the inner wall of the bottom of the circulation tank 100 are improved; on the other hand, the connecting base 38 and the stator base 31 can play a guiding role for the slurry in the radial direction of the circulation tank 100, so that most of the slurry thrown out by the dispersion mechanism 300 flows toward the inner wall of the circulation tank 100 and flows along the inner wall of the circulation tank 100, extending the circulation path, avoiding the slurry discharged by the dispersion mechanism 300 from quickly returning to the through hole 3101, improving the circulation capacity, and improving the dispersion effect and mixing effect of the slurry; on the other hand, the connection The base 38 and the stator base 31 are connected by a connecting rod 36 to form a dispersion chamber 301, thereby prompting most of the slurry in the dispersion chamber 301 to be discharged from the dispersion mechanism 300 after being sheared by the stator ring 33 and the rotor ring 13, avoiding the problem of the slurry in the dispersion chamber 301 not being sheared by the stator ring 33 and the rotor ring 13 and leaking into the inner cavity of the circulation tank 100, and weakening the impact force of the slurry outside the dispersion mechanism 300 on the internal structure of the dispersion mechanism 300, reducing the energy loss of the fluid in the dispersion mechanism 300, and improving the circulation capacity and dispersion capacity of the dispersion mechanism 300.

[0073] Please refer again Figure 1 and Figure 4 For example, in this embodiment, a mounting hole 102 for mounting the connecting base 38 is provided at the bottom of the circulation tank 100. Specifically, the edge of the connecting base 38 is sealed and connected to the mounting hole 102. The connecting base 38 and the circulation tank 100 can be directly connected; or, they can be fixedly connected through a third-party component, which is not specifically limited in this embodiment of the present application. The top wall of the connecting base 38 facing the stator base 31 serves as part of the bottom wall of the circulation tank 100, thereby installing the dispersion mechanism 300 and the circulation tank 100 on the edge, and reducing the gap between the slurry in the connecting base 38 and the bottom wall of the circulation tank 100.

[0074] In some embodiments, the stator 30 further includes a positioning sleeve 37, one end of which is connected to the stator base 31 and the other end of which is connected to the connecting base 38. The connecting rod 36 is inserted into the positioning sleeve 37. Thus, on the one hand, the positioning sleeve 37 can provide axial and circumferential positioning for the installation of the connecting rod 36, improving assembly efficiency and the reliability of the connection between the connecting rod and the circulation tank 100, thereby preventing displacement of the stator 30. On the other hand, the provision of the positioning sleeve 37 better achieves force transmission and distribution, thereby reducing flow resistance, and enhancing the stability and load-bearing capacity of the stator 30, thereby improving the reliability and stability of the connection between the stator 30 and the circulation tank 100 in the dispersed structure. In some embodiments, the positioning sleeve 37 can be provided with an internal thread, and the connecting rod 36 can be provided with an external thread that matches the internal thread of the positioning sleeve 37, thereby further improving the reliability and stability of the connection between the stator 30 and the circulation tank 100. The shear structure 363 is provided on the outer wall of the positioning sleeve 37.

[0075] The inner wall of the circulation tank 100 includes a tank top wall 1011, a tank bottom wall 1012, and a tank side wall 1013 connecting the tank top wall 1011 and the tank bottom wall 1012. The tank bottom wall 1012 is inclined relative to the tank side wall 1013 toward the side of the dispersion mechanism 300 and smoothly transitions to the top wall of the connection base 38 toward the stator base 31. Thus, on the one hand, the inclined tank bottom wall 1012 is used to guide the slurry to flow upward along the side wall of the circulation tank 100, thereby improving the circulation capacity of the dispersion mechanism 300. On the other hand, the tank bottom wall 1012 is smoothly transitioned to the top wall of the connection base 38 toward the stator base 31, thereby preventing some slurry from settling at the bottom and affecting slurry uniformity, improving slurry fluidity and continuity, promoting reciprocating circulation of the slurry, and improving slurry uniformity.

[0076] The gap between the rotor ring 13 and the stator ring 33 is a first gap 302. When the stator ring 33 located on the outermost ring of the stator base 31 is outside all the rotor rings 13, the gap between the connecting rod 36 and the stator ring 33 located on the outermost ring of the stator base 31 is a second gap 303. When the rotor ring 13 located on the outermost ring of the rotor base 11 is outside all the stator rings 33, the gap between the connecting rod 36 and the rotor ring 13 located on the outermost ring of the rotor base 11 is a second gap 303. The second gap 303 is larger than the first gap 302. Therefore, on the one hand, the radial dimension of the stator base 31 is increased, the guiding effect on the slurry is improved, the slurry discharged from the dispersion mechanism 300 is prevented from quickly returning to the through hole 3101, the circulation capacity of the slurry is improved, and the dispersion and mixing effects of the slurry are improved; on the other hand, the impact force of the slurry thrown out by the dispersion mechanism 300 on the connecting rod 36 is reduced, the reliability and stability of the connection between the dispersion structure and the circulation tank 100 are improved, and the risk of slurry backflow is reduced.

[0077] In some embodiments, the rotor ring 13 located at the outermost ring of the rotor base 11 is located outside all stator rings 33. Therefore, on the one hand, positioning the rotor ring 13 located at the outermost ring of the rotor base 11 outside all stator rings 33 can reduce mechanical vibration, reduce airflow interference, and balance the dynamic load of the rotor 10 during mechanical operation, thereby reducing vibration and noise caused by imbalance, thereby reducing noise and, in turn, reducing the noise generated by the dispersion mechanism 300 during the slurry dispersion process. On the other hand, increasing the linear speed of the rotor 10 improves the discharge capacity of the dispersion mechanism 300 and the material absorption capacity of the dispersion mechanism 300 on the side of the through hole 3101, promoting the reciprocating motion of the slurry, and improving the dispersion and mixing effects of the slurry.

[0078] For example, in this embodiment, the number of connecting rods 36 is less than the number of stator slots 331. Thus, on the one hand, the assembly efficiency of the stator 30 and the circulation tank 100 is improved, cost is saved, and the reliability and stability of the connection between the dispersion structure and the circulation tank 100 are improved; on the other hand, the discharge capacity of the dispersion mechanism 300 is improved, and the slurry is promoted to reciprocate in the circulation tank 100. Of course, in some embodiments, the number of connecting rods 36 can also be equal to the number of stator slots 331, and the embodiment of the utility model does not make a specific limitation. A plurality of connecting rods 36 are evenly arranged along the circumferential direction Z of the dispersion mechanism 300, thereby improving the force uniformity of the stator 30, improving the working stability of the dispersion mechanism 300, and reducing noise.

[0079] Please also refer to Figure 4 and Figure 5 , Figure 5 yes Figure 2 A schematic structural diagram of a fourth embodiment of the dispersion mechanism 300 of the circulating pulping equipment 1000 omitting the guide plate 34. In some embodiments, the stator 30 further includes a plurality of gaskets 365, and each connecting rod 36 includes a connecting rod portion 361 and a stop portion 362. Each gasket 365 is disposed between the stop portion 362 of the corresponding connecting rod 36 and the stator base 31. Thus, on the one hand, the gasket 365 can increase the contact area between the connecting rod 36 and the stator base 31, prevent the connecting rod 36 from loosening, improve the firmness and reliability of the connection between the connecting rod 36 and the stator base 31 and the connecting base 38, and strengthen the seal to prevent the slurry from affecting the connecting rod 36 and the stator base 31; on the other hand, the gasket 365 also has shock absorption and buffering functions, reducing the noise generated by the dispersion mechanism 300 during the dispersion process. Specifically, the gasket 365 is disposed between the stop portion 362 and the second base 312.

[0080] In some embodiments, the stator 30 further includes a connecting ring 366, and a plurality of gaskets 365 are fixedly connected to the connecting ring 366. Thus, the provision of the connecting ring 366 can improve the assembly efficiency and assembly yield of the gasket 365 and the stator base 31, and prevent the gasket 365 from shifting. Exemplarily, the connecting ring 366 and the gasket 365 are convexly arranged on the top wall of the stator base 31, thereby facilitating the processing and manufacturing of the stator base 31. In some embodiments, the stator base 31 is provided with a positioning groove, and the connecting ring 366 and the gasket 365 can be arranged in the positioning groove, so that the top wall of the stator base 31 forms a continuous flat surface, thereby improving the smoothness of the slurry flow, promoting the slurry to perform reciprocating circulation in the circulation tank 100, improving the circulation capacity of the slurry, and improving the dispersion effect and mixing effect of the slurry.
