Description

Technical Field

[0001] The present application relates to the field of pulping technology, and in particular to a dispersion component and a dispersion device. Background Art

[0002] Existing dispersing equipment includes a stator and rotor that are rotatably coupled. However, when the stator ring has the same number of slots as the rotor ring, vibrations at the blade-passing frequency can occur between the stator blades and the rotor. This increases the vibration and noise generated by the dispersing equipment during the slurry dispersion process, disrupting the work environment and operators. Summary of the Invention

[0037] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] It should be understood that the terms used in the specification, claims, and accompanying figures of this application are intended only to describe specific embodiments and are not intended to limit this application. The terms "first," "second," and so on in the specification, claims, and accompanying figures of this application are used to distinguish between different objects and are not intended to describe a specific order. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "the" are intended to include the plural forms. The terms "including" and "comprising" and any variations thereof are intended to cover non-exclusive inclusions. Furthermore, this application may be implemented in a variety of different forms and is not limited to the embodiments described herein. The following specific examples are provided to facilitate a clearer and more thorough understanding of the disclosure of this application. Words such as "up," "down," "left," and "right" refer only to the positions of the structures shown in the corresponding accompanying drawings. In the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," "connected," and "disposed on" are to be broadly construed. For example, they may refer to fixed, removable, or integral connections; mechanical connections; direct connections or indirect connections through an intermediary; and internal connections between two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] The term "slurry" refers to a material in a stable suspension state formed by mixing and dispersing a powder and a liquid. Powder refers to a material in powder form, and liquid refers to a material in liquid form.

[0040] The term "dispersion" refers to the process by which particle agglomerates in a slurry are fully disintegrated to form a stable solid-liquid suspension system.

[0041] The following 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.

[0042] Please also refer to Figure 1 and Figure 2 , Figure 1 1 is a schematic structural diagram of a dispersion device 1000 provided in the first embodiment of the present application. Figure 2 yes Figure 1 1 is a cross-sectional view of a dispersion device 1000. Dispersion device 1000 includes a housing 100 and a dispersion assembly 200. Housing 100 is provided with a receiving chamber 101. Dispersion assembly 200 is disposed within receiving chamber 101. Thus, dispersion assembly 200 can achieve functions such as dispersion, homogenization, emulsification, or pulverization of the slurry.

[0043] The housing 100 is configured as a hollow shell. The housing 100 is provided with a silencing chamber 105 separated from the accommodating chamber 101. In this embodiment, the silencing chamber 105 is connected to an external vacuum device. Specifically, the housing 100 is provided with a suction port 106 connected to the silencing chamber 105 and the vacuum device. Thus, based on the connection between the silencing chamber 105 and the external vacuum device, the gas density is reduced, the sound wave propagation medium is reduced, the air-conducted noise is weakened, and the high-frequency impact noise generated by the collapse of cavitation bubbles is suppressed. In addition, the vacuum environment of the silencing chamber 105 can also reduce the transmission of structural vibrations.

[0044] Of course, in some embodiments, a sound-absorbing structure (not shown) is provided in the silencing cavity 105. Thus, by filling the silencing cavity 105 provided in the housing 100 with the sound-absorbing structure, the sound-absorbing structure converts sound energy into heat energy through friction and viscosity effects, thereby achieving a noise reduction effect for the dispersion device 1000.

[0045] In this embodiment, the housing 100 includes a housing body 110 and a cover 120. The housing body 110 and the cover 120 are connected to form a housing cavity 101. The cover 120 is detachably connected to the housing body 110, thereby facilitating the assembly, maintenance, and tilting of the various components of the dispersion device 1000. Specifically, the dispersion assembly 200 is detachably mounted within the housing cavity 101. This facilitates assembly of the housing 100 and the dispersion assembly 200, resulting in a rational layout and a compact structure. It also facilitates cleaning and maintenance of the components of the dispersion device 1000.

[0046] The housing 100 is also provided with a feed port 102 and a discharge port 103 that are in communication with the accommodating chamber 101. The feed port 102 is provided at the top of the housing 100. The discharge port 103 is provided on the side wall of the housing 100. Specifically, the feed port 102 is provided in the middle of the cover 120. The discharge port 103 is provided on the side wall of the housing body 110. The housing body 110 has a generally cylindrical shape. The opening direction of the discharge port 103 extends along the tangential direction of the housing body 110, thereby improving the discharge efficiency of the dispersion device 1000.

[0047] It is understandable that when the dispersion device 1000 is used for slurrying, slurry can be added to the feed port 102 of the housing 100, and the dispersion component 200 can be started to perform operations such as shearing, dispersing and mixing the slurry. In some embodiments, the vacuum device can also be started when the dispersion component 200 is in operation, thereby reducing the noise generated by the dispersion device 1000 during operation. The radial dimension of the feed port 102 in the radial direction Y of the dispersion component 200 gradually increases along the flow direction of the slurry, so that the gradually expanding feed port 102 can guide the material to enter the dispersion area smoothly, reduce turbulence and dead corners, avoid material accumulation or blockage, and improve the pumping capacity of the dispersion device 1000 for the slurry, reduce inlet turbulence, and smoothly transition to the dispersion area. Of course, in some embodiments, the radial dimension of the feed port 102 in the radial direction Y of the dispersion component 200 can also remain unchanged or gradually decrease along the flow direction of the slurry, and the embodiments of the present application are not specifically limited.

[0048] Dispersing device 1000 also includes a rotating shaft 300 and a drive element. Dispersing assembly 200 includes a stator 20 and a rotor 40 that are rotatably coupled. Stator 20 is fixedly connected to housing 100, while rotor 40 is rotatably disposed relative to stator 20. The rotating shaft 300 is in driving connection with rotor 40 of dispersing assembly 200. The drive element is used to drive rotor 40 to rotate about a rotation axis P of the rotating shaft 300, thereby enabling dispersing assembly 200 to disperse the slurry within housing 100.

[0049] It should be noted that Figure 1 The purpose is only to schematically describe the arrangement between the housing 100 and the dispersed component 200, and is not to specifically limit the connection position, connection relationship and specific structure of each component. Figure 1 The structure of the dispersion device 1000 is only shown in the embodiment of the present application and does not constitute a specific limitation on the dispersion device 1000. In other embodiments of the present application, the dispersion device 1000 may include Figure 1 More or fewer components, or combinations of certain components, or different components, such as the dispersion device 1000 may also include, but are not limited to, a locking structure. The locking structure is used to mount the stator 20. Specifically, the stator 20 is fixedly mounted on the housing 100 of the dispersion device 1000 via the locking structure.

[0050] For the accuracy of description, please refer to the direction in this article. Figure 1For reference, the rotor 40 has a rotation axis P. The rotation axis P of the rotor 40 is the central axis of the shaft 300. The rotor 40 rotates relative to the stator 20 about the rotation axis P of the shaft 300. The term "axial direction X" refers to the direction parallel to the rotation axis P of the rotor 40, i.e., the up-down direction (where the positive direction of the X axis is upward). The term "radial direction Y" refers to the direction perpendicular to the rotation axis P of the rotor 40, i.e., the radial direction along the cross-section of the shaft 300, i.e., the left-right direction (where the positive direction of the Y axis is right). The term "circumferential direction Z" refers to the circumferential direction of the shaft 300, i.e., the direction surrounding the rotation axis P of the rotor 40. The axial direction X, radial direction Y, and circumferential direction Z together constitute the three orthogonal directions of the rotor 40. The axial direction X, radial direction Y, and circumferential direction Z of the rotor 40 can be customized based on the specific structure of the product and the perspective of the drawings, and are not specifically limited in this application. For ease of description, directions such as up, down, left, and right in this application are relative and do not constitute limitations. The axial direction X of the dispersion assembly 200 is parallel to the axial direction X of the rotor 40 , the radial direction Y of the dispersion assembly 200 is parallel to the radial direction Y of the rotor 40 , and the circumferential direction Z of the dispersion assembly 200 is parallel to the circumferential direction Z of the rotor 40 .

[0051] Please also refer to Figure 2 and Figure 3 , Figure 3 yes Figure 1 A schematic structural diagram of the dispersion assembly 200 of the dispersion device 1000 from a first perspective is shown. The rotor 40 includes a rotor base 41 and at least one rotor ring 42. Each rotor ring 42 is fixed to the rotor base 41. Each rotor ring 42 is provided with a plurality of rotor slots 401 along the circumferential direction Z of the dispersion assembly 200. The stator 20 includes a stator base 21 and at least one stator ring 22. Each stator ring 22 is provided with a plurality of stator slots 201 along the circumferential direction Z of the dispersion assembly 200. The stator rings 22 and the rotor rings 42 are arranged alternately along the radial direction Y of the dispersion assembly 200. In adjacent rotor rings 42 and stator rings 22, the number of stator slots 201 is different from the number of rotor slots 401.

[0052] The dispersion component 200 provided in the present application is based on the fact that the number of stator slots 201 is different from the number of rotor slots 401 in the adjacent rotor ring 42 and stator ring 22, thereby reducing the risk of vibration of the rotor 40 passing frequency occurring between the stator ring 22 and the rotor ring 42, reducing the vibration and noise generated by the dispersion equipment 1000 during the process of dispersing the slurry, and reducing the interference of the high-frequency noise generated by the dispersion component 200 during operation to the working environment and operators, thereby improving the working environment, improving work efficiency and extending the service life of the dispersion component 200.

[0053] Illustratively, in this embodiment, the slurry can be a battery slurry. Battery slurry includes a variety of materials, such as but not limited to solvents, conductive agents, liquids or powders, etc., and various materials are mixed to form battery slurry. Powders include but are not limited to active substances, conductive agent powders, adhesive powders and other powder materials. Liquids include but are not limited to liquids such as conductive agent solutions and adhesive solutions. Liquids can also include liquids obtained by mixing powders and liquids. In this embodiment, the slurry is illustrated as a battery slurry. It can be understood that the dispersion component 200 can also be used to disperse other slurries, such as food, medicine, fertilizers, building materials, etc., and the application of the dispersion component 200 is not limited here.

[0054] The stator base 21 and all stator rings 22 can be connected to form an integrated structure, thereby improving the overall structural strength of the stator 20 and extending the service life of the stator 20. For example, the stator base 21 and all stator rings 22 can be fixedly connected together through one-piece molding, welding, or bonding. Of course, in some embodiments, the stator base 21 and all stator rings 22 can also be configured as a split structure. Specifically, the stator base 21 and all stator rings 22 are independently provided and fixedly connected. For example, the stator base 21 and all stator rings 22 can be fixedly connected together through a locking structure, a snap-fit ​​structure, a screw-fit structure, or the like.

[0055] The rotor base 41 and all the rotor rings 42 can be connected to form an integrated structure, thereby improving the overall structural strength of the rotor 40 and extending the service life of the rotor 40. For example, the rotor base 41 and all the rotor rings 42 can be fixedly connected together by integral molding, welding, or bonding. Of course, in some embodiments, the rotor base 41 and all the rotor rings 42 can also be configured as a split structure. Specifically, the rotor base 41 and all the rotor rings 42 are independently provided and fixedly connected. For example, the rotor base 41 and all the rotor rings 42 can be fixedly connected together by a locking structure, a clamping structure, a screwing structure, or the like.

[0056] For example, in this embodiment, the number of stator slots 201 in adjacent rotor rings 42 and stator rings 22 is greater than the number of rotor slots 401. Therefore, by setting the number of stator slots 201 greater than the number of rotor slots 401, on the one hand, the frequency at which the rotor 40 passes through the stator slots 201 (i.e., the passing frequency) is increased, but the number of interactions between the rotor ring 42 and the stator ring 22 in each cycle increases, resulting in energy dispersion to a higher frequency band, making high-frequency noise more easily absorbed or attenuated by the equipment structure, thereby reducing high-frequency noise. On the other hand, the meshing frequency of the rotor 40 and the stator slots 201 is higher, but the amplitude of the single meshing force may be reduced, dispersing the periodic impact on the fluid or slurry, thereby reducing the overall vibration amplitude and the resonant noise caused by the superposition of periodic pulses. On the other hand, more stator slots 201 help to achieve more uniform shearing of the slurry during passage, reduce local pressure fluctuations, and thus suppress fluid-induced vibrations, thereby improving the uniformity of slurry flow. Of course, in some embodiments, the number of stator slots 201 corresponding to any one stator 20 is greater than the number of rotor slots 401 corresponding to any one rotor 40 .

[0057] In some embodiments, in adjacent rotor rings 42 and stator rings 22, the ratio of the number of stator slots 201 to the number of rotor slots 401 is a non-integer multiple. This prevents the number of stators 20 and rotors 40 from being an integer multiple, thereby reducing resonance noise caused by periodic pulse superposition.

[0058] In some embodiments, in adjacent rotor rings 42 and stator rings 22, the ratio of the number of stator slots 201 to the number of rotor slots 401 is in the range of 1.1-1.5. It is understandable that if the ratio of the number of stator slots 201 to the number of rotor slots 401 is too small, the number of stator slots 201 is close to the number of rotor slots 401, which may cause mechanical resonance, resulting in increased vibration of the equipment, increased noise, and even damage to components. In addition, the shearing effect of the dispersion component 200 on the slurry fluid is insufficient, and the slurry may not be fully dispersed or homogenized, affecting the treatment effect; and when the ratio of the number of stator slots 201 to the number of rotor slots 401 is too large, the slurry fluid is easily over-sheared, the flow resistance increases, the energy loss increases, and even local eddy currents or cavitation may be caused, reducing the mixing efficiency. Therefore, the embodiment of the present application sets the ratio of the number of stator slots 201 to the number of rotor slots 401 within a reasonable ratio range to disperse the mechanical pulse energy to a wider frequency band, avoid energy concentration at a single frequency, and improve the noise of the working environment. For example, the ratio of the number of stator slots 201 to the number of rotor slots 401 may be, but is not limited to, 1.1, 1.2, 1.3, 1.4, or 1.5. The ratio of the number of stator slots 201 to the number of rotor slots 401 may be set based on factors such as slurry properties and the specifications of the dispersion assembly 200, and is not specifically limited in this embodiment of the present application.

[0059] In adjacent rotor rings 42 and stator rings 22, the number of stator slots 201 is 32-40, and the number of rotor slots 401 is 21-36. It is understandable that when the number of stator slots 201 provided on the stator ring 22 is too small, it is easy to cause uneven distribution of slurry shear frequency, insufficient shearing in local areas, affecting the final dispersion fineness of the slurry. In addition, the frequency of the rotor 40 passing through the stator slots 201 is low. If it is close to the natural frequency of the equipment structure, it is easy to cause resonant noise. When the number of stator slots 201 provided on the stator ring 22 is too large, the frequency of the rotor 40 passing through the stator slots 201 is higher, but the single impact energy is smaller, and the noise tends to be high-frequency, making it easier for the noise to be absorbed or attenuated by the dispersion device 1000. However, too many stator slots 201 increase the resistance to material passage, increase energy consumption, easily cause the risk of blockage, and increase the wear of the stator ring 22. Therefore, on the one hand, the embodiment of the present application is based on setting the number of stator slots 201 within a suitable range to reduce the risk of vibration of the rotor 40 passing frequency between the stator ring 22 and the rotor ring 42, as well as to improve the shear dispersion ability of the stator 20 and the rotor 40 and extend the service life of the stator 20. On the other hand, the number of rotor slots 401 is adapted to the number of stator slots 201 to reduce the resonance noise caused by the superposition of periodic pulses.

[0060] For example, in this embodiment, the number of stator slots 201 is 36, and the number of rotor slots 401 is 30. It should be noted that the number of stator slots 201 and the number of rotor slots 401 can be set according to factors such as the type of slurry and the specifications of the dispersion assembly 200, which are not specifically described in this embodiment. For example, the number of stator slots 201 can be, but is not limited to, 32, 33, 34, 35, 36, 37, 38, 39, or 40. The number of rotor slots 401 can be, but is not limited to, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, or 36.

[0061] In this embodiment, the number of stator rings 22 is set to multiple. At least some of the stator rings 22 correspond to different numbers of stator slots 201. Therefore, by setting different numbers of stator rings 22, noise energy can be dispersed by differentiating the frequencies of the stator rings 22, effectively suppressing single-frequency resonance and noise peaks. This reduces the interference of high-frequency noise generated by the dispersion assembly 200 during operation on the work environment and operators, improving the work environment, increasing work efficiency, and extending the service life of the dispersion assembly 200. Of course, in some embodiments, the number of stator rings 22 can also be set to one.

[0062] Please also refer to Figures 3 to 5 , Figure 4 yes Figure 3 A schematic structural diagram of the second perspective of the dispersed component 200; Figure 5 yes Figure 4 A cross-sectional view of the dispersion component 200 along line II. In some embodiments, two adjacent stator rings 22 are defined as a first stator ring 221 and a second stator ring 222. The first stator ring 221 is located on the inner side of the second stator ring 222. The number of stator slots 201 provided on the second stator ring 222 is less than the number of stator slots 201 provided on the first stator ring 221. It can be understood that since the number of stator slots 201 provided on the multiple stators 20 of the traditional dispersion component 200 is the same, the existing dispersion component 200 easily causes flow separation and coexistence of multi-scale vortices when the slurry fluid passes through the stator slots 201, and is accompanied by strong turbulent pulsations, thereby causing serious noise during the operation of the dispersion device 1000. Therefore, the embodiment of the present application is based on the number of stator slots 201 of the stator ring 22 gradually decreasing from the inside to the outside, so as to effectively suppress the vortex core and thereby weaken the noise of the fluid passing through.

[0063] In some embodiments, the ratio of the number of stator slots 201 provided on the first stator ring 221 to the number of stator slots 201 provided on the second stator ring 222 is 1.1-1.5. It is understandable that when the ratio of the number of stator slots 201 provided on adjacent stator rings 22 is too close, the passing frequencies of all stator rings 22 are approximately the same, the pulse energy is superimposed, and a strong single-frequency noise peak is generated, which is easy to induce resonance. When the ratio of the stator slots 201 on the inner stator ring 22 to the stator slots 201 on the outer stator ring 22 is too large, the slurry fluid is prone to blockage, excessive shearing of the inner ring will cause the slurry to be refined prematurely, and the outer ring cannot effectively supplement the shearing due to insufficient flow, resulting in an unbalanced shear force distribution. Although the multiple slots in the inner ring cause the passing frequency of the stator ring 20 to shift to a high frequency, it may excite the natural frequency of the stator 20 support structure and generate noise. Thus, by setting the number of stator slots 201 corresponding to the inner and outer stator rings 22 within an appropriate ratio, the embodiment of the present application reduces the risk of noise and vibration generated by the dispersion assembly 200 during the dispersion process, avoids slurry blockage, and improves the shearing and dispersion effects of the slurry. The ratio of the number of stator slots 201 provided on the first stator ring 221 to the number of stator slots 201 provided on the second stator ring 222 can be, but is not limited to, 1.1, 1.2, 1.3, 1.4, or 1.5. For example, in this embodiment, the number of stator rings 22 is set to two, the number of stator slots 201 provided on the first stator ring 221 is 36, and the number of stator slots 201 provided on the second stator ring 222 is 32. The ratio of the number of stator slots 201 provided on the first stator ring 221 to the number of stator slots 201 provided on the second stator ring 222 is 1.125.

[0064] Please also refer to Figure 3 、 Figure 5 and Figure 6 , Figure 6 yes Figure 3 is a cross-sectional view of the dispersion assembly 200 in FIG. In this embodiment, the number of stator rings 22 is set to be multiple. The multiple stator rings 22 have the same thickness along the radial direction Y of the dispersion assembly 200. The number of rotor rings 42 is set to be multiple. The thickness of the rotor ring 42 located on the innermost side along the radial direction Y of the dispersion assembly 200 is a first thickness D1. The thickness of the rotor ring 42 located on the outermost side along the radial direction Y of the dispersion assembly 200 is a second thickness D2. The first thickness D1 is less than the second thickness D2. It can be understood that when the self-priming of the dispersion assembly 200 is insufficient, the high-speed rotation of the rotor 40 is likely to form low-pressure cavitation at the feed inlet 102, resulting in shear force fluctuations. Therefore, based on the thickness of the outer rotor ring 42 being greater than the thickness of the inner rotor ring 42, on the one hand, the thin thickness (low inertia) of the inner rotor ring 42 is conducive to rapid startup and material suction, and the thickness (high kinetic energy) of the outer rotor ring 42 provides stronger shear force, enhances the self-priming ability of the dispersion assembly 200, and ensures that the material enters the high shear zone evenly; on the other hand, the thin cross-section of the inner rotor ring 42 reduces the initial resistance to the material and promotes smooth entry of the material, while the thick cross-section of the outer rotor ring 42 enhances the squeezing and shearing of the material, thereby improving the dispersion effect; on another hand, since the outer edge of the rotor ring 42 has the highest linear velocity and is subjected to the greatest centrifugal force and shear force, the increased outer edge thickness of the rotor ring 42 can enhance the structural strength and prevent deformation or breakage, and the thick outer edge can increase the moment of inertia, reduce the risk of vibration during high-speed rotation, and ensure smooth operation.

[0065] In some embodiments, the stator ring 22 has a third thickness D3 along the radial direction Y of the dispersion assembly 200. Third thickness D3 is less than second thickness D2. As a result, the thicker rotor 40 can generate greater mechanical energy, while the thinner stator 20 can reduce material obstruction, concentrating shear forces on the gap between the rotor 40 and stator 20, thereby improving slurry dispersion.

[0066] The first thickness D1 is 4mm-5mm. The difference between the second thickness D2 and the first thickness D1 is 3mm-4mm. It can be understood that the thicker the rotor ring 42, the narrower the fluid channel. Under the action of the centrifugal force of the rotor 40, the slurry fluid speed is faster, thereby strengthening the self-priming ability of the dispersion component 200. However, excessive self-priming ability can easily lead to insufficient residence time of the slurry in the shear zone, reducing the dispersion fineness. Conversely, the thinner the rotor ring 42, the wider the fluid channel. Under the action of the centrifugal force of the rotor 40, the slurry fluid speed is slower, and the self-priming ability of the dispersion component 200 is weaker. However, excessive self-priming ability can easily lead to excessive residence time of the slurry in the shear zone, thereby damaging the quality of the slurry. Therefore, the present application sets the thickness of the outermost rotor ring 42 and the innermost rotor ring 42 within a preset range, thereby ensuring that the slurry can smoothly enter the shear zone and ensure that the slurry is fully sheared and dispersed in the shear zone to improve the dispersion effect of the slurry. The first thickness D1 can be, but is not limited to, 4 mm, 4.2 mm, 4.4 mm, 4.5 mm, 4.6 mm, 4.8 mm, or 5 mm. The difference between the second thickness D2 and the first thickness D1 is 3 mm, 3.2 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.8 mm, or 4 mm. It should be noted that the first thickness D1 and the second thickness D2 can be set based on factors such as the slurry type and the specifications and material of the dispersion assembly 200, and are not specifically limited in this embodiment of the application.

[0067] In some embodiments, the thickness of the plurality of rotor rings 42 along the radial direction Y of the dispersion assembly 200 gradually increases from the inside to the outside. Therefore, based on the setting that the thickness of the stator 20 remains unchanged, the thickness of the rotor 40 gradually increases from the inside to the outside. On the one hand, the structure with a thin inner layer and a thick outer layer can form a shear force gradient, so that the thin thickness (low inertia) of the inner ring rotor ring 42 is conducive to rapid startup and material suction, and the thick outer ring rotor ring 42 (high kinetic energy) provides stronger shear force, and makes the dispersion component 200 suitable for dispersing high-viscosity or high-hardness materials, and enables the slurry fluid to maintain a stable flow state and improve shear continuity; on the other hand, the static pressure of the slurry fluid decreases after being accelerated by centrifugal force (Bernoulli principle), forming a low-pressure suction port, forcing the slurry to be sucked in from the axial direction and discharged radially, thereby improving the self-priming ability of the dispersion component 200; on the other hand, the thickness gradient change causes the slurry to flow at high speed on the inside to pre-disperse the agglomerates, and decelerate and increase the pressure on the outside, extending the shear residence time, thereby improving the shear efficiency of the slurry; on the other hand, the gradually thickening design of the rotor ring 42 avoids sudden changes in the flow channel, reduces turbulence and cavitation generation, and reduces high-frequency noise.

[0068] See also Figure 3 and Figure 5In some embodiments, the angle formed between the slotting direction of the rotor slots 401 and the radial direction Y of the dispersion assembly 200 is a first angle, and the angle formed between the slotting direction of the stator slots 201 and the radial direction Y of the dispersion assembly 200 is a second angle, where the first angle and the second angle are different. Thus, by setting the rotor slots 401 and the stator slots 201 to extend in different directions, on the one hand, the slurry can undergo multi-directional shear, and the anisotropic slots force the fluid to continuously change direction, filling the entire shear zone, improving the efficiency of agglomerate breakup and avoiding local overheating or uneven dispersion. On the other hand, the stator slots 201 and the rotor slots 401 intersect, disrupting the pulse periodicity, dispersing the energy over a wide frequency band, and reducing the noise generated by the dispersion assembly 200 during the slurry dispersion process.

[0069] The first angle is denoted as α. The second angle is denoted as β. 20°≤α≤30°, 30°≤β≤40°. Thus, the slot angles of the stator slots 201 can be coordinated with the slot angles of the rotor slots 401. This, on the one hand, avoids flow shock and ensures that the slurry flow satisfies the velocity triangle continuity condition, thereby achieving low energy consumption and high dispersion efficiency. Velocity continuity reduces fluid separation and backflow, resulting in a more uniform pressure distribution and avoiding slurry flow path-induced equipment vibration. Furthermore, it prevents localized erosion of the edges of the stator slots 201 by the impact flow, thereby extending the service life of the dispersion assembly 200. The first angle is, for example, but not limited to, 20°, 22°, 24°, 26°, 28°, or 30°. The second angle is, for example, but not limited to, 30°, 32°, 34°, 36°, 38°, or 40°. It should be noted that the first and second angles can be set based on factors such as the slurry type and the specifications and materials of the dispersion assembly 200, and are not specifically limited in this embodiment.

[0070] For example, in this embodiment, the rotor slots 401 provided on the multiple rotor rings 42 are arranged in a one-to-one correspondence in the radial direction Y of the dispersion assembly 200. Thus, on the one hand, the aligned multiple rotor slots 401 can make the flow direction of the slurry fluid more consistent, reduce disordered vortexes, and improve the uniformity of slurry dispersion; on the other hand, the aligned multiple rotor slots 401 allow the shear force of the rotor ring 42 to be superimposed at the same position in the radial direction of the dispersion assembly 200, thereby improving energy utilization and reducing the difficulty of machining the rotor 40. Of course, in some embodiments, the rotor slots 401 provided on the multiple rotor rings 42 are staggered in the radial direction Y of the dispersion assembly 200, which is not specifically limited in this embodiment of the present application.

[0071] In some embodiments, the outermost rotor ring 42 is located inside the outermost stator ring 22. Thus, when the rotor 40 rotates at high speed, the slurry is guided by the stator ring 22 to form a specific flow path within the shear zone of the dispersion assembly 200, thereby better controlling the slurry flow and ensuring that the slurry is subjected to stronger hydraulic shear, centrifugal extrusion, high-speed cutting, impact, and grinding when passing through the narrow gap between the rotor 40 and the stator 20, thereby improving the dispersion and mixing effects of the dispersion assembly 200. Furthermore, the outermost portion of the dispersion assembly 200 is provided with the stator ring 22, thereby reducing mechanical vibration, airflow interference, and balancing the dynamic load of the rotor 40 during mechanical operation, thereby reducing vibration and noise caused by imbalance, thereby reducing noise, and further reducing the noise generated by the dispersion assembly 200 during the slurry dispersion process.

[0072] Please refer again Figure 3 、 Figure 6 and Figure 7 , Figure 7 It is a cross-sectional view of a dispersion mechanism 200a in the prior art. In this embodiment, the dispersion assembly 200 further includes a flow guide 50. The flow guide 50 is fixed to the rotor base 41, and all rotor rings 42 are arranged around the outside of the flow guide 50. The flow guide 50 is configured as a conical structure or a quasi-conical structure. It can be understood that the impeller 50a of the traditional dispersion mechanism 200a includes a base 51a and blades 52a arranged on the base 51a. When the dispersion mechanism 200a sucks in the slurry, the slurry fluid contacts the high-speed rotating blades 52a, and the slurry fluid impacts the leading edge of the blades 52a, thereby forming local high-pressure areas and low-pressure areas, and inducing flow separation. The asymmetric separation vortex will generate noise and vibration, thereby affecting the user experience. The present application provides a conical structure or a quasi-conical structure on the rotor base 41, that is, the guide member 50 provided in the embodiment of the present application is configured as a bladeless impeller. On the one hand, the conical or quasi-conical setting of the guide member 50 can divert the slurry fluid, reduce the resistance of the rotating shaft 300 during rotation, and reduce energy consumption, thereby weakening the noise and vibration caused by the impact of the slurry fluid on the guide member 50, extending the service life of the dispersion component 200, and avoiding the problem of reduced flow rate of the slurry fluid due to flow field interference; on the other hand, it avoids the formation of a dead loop of the slurry fluid in the inlet area of ​​the dispersion component 200, promotes the slurry to enter the shear zone of the dispersion component 200, and improves the dispersion effect of the slurry; on the other hand, the conical or quasi-conical setting of the guide head 52 can buffer and disperse the material, and avoid the deformation of the rotating shaft 300 due to the impact of the material; on the other hand, the conical or quasi-conical setting of the guide head 52 can also break up the agglomerates in the slurry to ensure the quality and consistency of the pulping.

[0073] For example, in this embodiment, the flow guide 50 includes a flow guide body 51 and a flow guide head 52. The flow guide head 52 is configured to be fixedly connected to the rotating shaft 300. The flow guide body 51 is fixedly connected to the rotor base 41 and is located between the flow guide head 52 and the rotor base 41. The flow guide body 51 is configured as a frustum or a frustum-like structure. The flow guide head 52 is configured as a hemispherical structure, a cone structure, or a cone-like structure. Therefore, on the one hand, based on the configuration of the flow guide body 51 as a frustum or a frustum-like structure. The guide head 52 is configured as a hemispherical structure, a conical structure, or a quasi-conical structure, thereby reducing the noise and vibration caused by the impact of the slurry fluid on the guide member 50, extending the service life of the guide member 50, and improving the slurry fluid diversion effect, promoting the slurry to enter the shearing area of ​​the dispersion assembly 200. On the other hand, the guide head 52 is used to define the installation position of the rotor 40 relative to the rotating shaft 300, so that the guide member 50 and the rotor 40 can rotate synchronously with the rotation of the rotating shaft 300, achieving shear and dispersion of the slurry by the dispersion assembly 200, avoiding the problem of vibration and shaking of the rotor 40 relative to the rotating shaft 300, improving the stability of the rotating shaft 300, ensuring the smooth operation of the dispersion assembly 200, reducing the wear of the dispersion assembly 200 by the slurry, and facilitating the installation of the guide member 50, the rotor 40, and the rotating shaft 300. Specifically, one end of the rotating shaft 300 is connected to the driving member, and the other end of the rotating shaft 300 is fixedly connected to the guide head 52.

[0074] In this embodiment, the flow guide 51 and the rotor base 41 can be connected to form an integrated structure, thereby improving the overall structural strength of the rotor 40 and the flow guide 50 and extending the service life of the dispersion assembly 200. For example, the flow guide 51 and the rotor base 41 can be fixedly connected together by integral molding, welding, or bonding. Of course, in some embodiments, the flow guide 51 and the rotor base 41 can also be configured as a split structure. Specifically, the flow guide 51 and the rotor base 41 are independently provided and fixedly connected. For example, the flow guide 51 and the rotor base 41 can be fixedly connected together by a locking structure, a snap-fit ​​structure, a screw-fit structure, etc. The flow guide head 52 and the flow guide 51 are detachably connected, thereby facilitating the assembly, maintenance, replacement, and other operations of the rotating shaft 300, the flow guide head 52, and the flow guide 51.

[0075] In this embodiment, the flow guide 50 also includes a limiter 53. The limiter 53 is clamped between the flow guide head 52 and the flow guide body 51. The limiter 53 is smoothly and fixedly connected to the flow guide head 52 and the flow guide body 51, and is configured as a frustum structure. Therefore, on the one hand, the setting of the limiter 53 can reduce the risk of wear on the flow guide body 51 caused by the flow guide head 52 rotating with the rotating shaft 300, thereby extending the service life of the rotor 40 and reducing maintenance costs; on the other hand, the setting of the limiter 53 can also weaken the noise and vibration caused by the impact of the slurry fluid on the flow guide body 51, thereby extending the service life of the flow guide 50 and improving the smoothness and stability of the flow of the slurry fluid. Of course, in some embodiments, the flow guide 50 may only include the flow guide body 51 and the flow guide head 52; or, only include the flow guide body 51, which is not specifically limited in the embodiments of the present application.

[0076] In some embodiments, the guide member 50 also includes a sealing ring 54, and the limiting body 53 is sealedly connected to the guide head 52 and the guide body 51 through the sealing ring 54, thereby preventing the slurry from entering the gap between the guide head 52 and the guide body 51 and the rotating shaft 300, reducing the wear between the rotating shaft 300 and the guide member 50, and extending the service life of the dispersion component 200.

[0077] In this embodiment, the bladeless impeller has a continuous and smooth guide surface 5101 on the side of the dispersion assembly 200 that is close to the rotor ring 42 in the radial direction Y. Thus, the bladeless impeller's guide surface 5101 is continuously and smoothly arranged, thereby reducing the resistance boundary layer, allowing the slurry to flow stably along the wall, avoiding the turbulent impact of the conventional impeller 50a, and reducing the amount of slurry remaining on the guide member 50.

[0078] In some embodiments, a guide channel 5102 is formed between the guide surface 5101 and the inner sidewall of the innermost rotor ring 42. The width of the guide channel 5102 in the radial direction Y of the dispersion assembly 200 gradually increases from the side closest to the rotor 40 baseplate toward the side further away from the rotor 40 baseplate. By arranging the guide channel 5102 to gradually narrow from top to bottom, the guide channel 5102 increases the flow area, thereby reducing flow velocity (according to the continuity equation), improving flow field stability, and improving inflow conditions. Furthermore, reducing flow velocity increases the static pressure of the fluid according to the Bernoulli equation. The increased inlet pressure can delay cavitation initiation and reduce cavitation noise.

[0079] Please also refer to Figure 3 and Figures 7 to 9 , Figure 8 yes Figure 7 Flow field simulation diagram of the dispersion mechanism 200a; Figure 9 yes Figure 1Flow field simulation diagram of the dispersion component 200 in the figure. The traditional dispersion mechanism 200a includes a stator component 20a and a rotor component 40a. The rotor component 40a can be rotatably matched with the stator component 20a. The impeller 50a is fixed on the rotor component 40a. In the traditional dispersion mechanism 200a, when the slurry fluid contacts the blades 52a of the impeller 50a, the slurry fluid impacts the leading edge of the blades 52a, forming local high-pressure areas and low-pressure areas, causing flow separation. This asymmetric separation vortex will cause the dispersion mechanism 200a to generate noise and vibration during the dispersion operation, and the slurry forms a vortex in the edge area at the top of the blade 52a, thereby reducing the suction capacity of the slurry. In the embodiment of the present application, the guide body 51 of the guide member 50 is configured as a bladeless impeller. When the rotor 40 rotates at high speed, the smooth surface of the guide body 51 reduces the flow resistance of the slurry on the guide surface 5101 of the guide body 51, promoting axial circulation of the slurry from top to bottom, avoiding the problem of local vortex retention caused by the blades 52a of the traditional impeller 50a, improving flow field stability, improving the slurry inflow conditions, and reducing the noise generated by cavitation during the dispersion operation of the dispersion assembly 200. It also reduces damage to the guide member 50 and reduces the maintenance cost of the dispersion assembly 200. In addition, the bladeless configuration of the guide member 50 can more quickly transport the slurry to the shear zone between the rotor 40 and stator 20, thereby indirectly improving the dispersion efficiency of the dispersion assembly 200.
