Description

Technical Field

[0001] This utility model relates to the field of slurry dispersion technology, and in particular to a continuous disperser. Background Technology

[0002] In the preparation of lithium battery slurry, the positive electrode (lithium iron phosphate, conductive agent powder, and polyvinylidene fluoride solution) and the negative electrode (graphite, conductive agent, and carboxymethyl cellulose) all require uniform mixing, dispersion, and viscosity reduction. Polyvinylidene fluoride and carboxymethyl cellulose act as binders, binding the various powders together and increasing the slurry viscosity to form agglomerates of varying sizes during mixing. However, these agglomerates can degrade the electrochemical performance of the resulting lithium battery. Therefore, a disperser is needed to break up the agglomerates in the slurry, ensuring uniform mixing and reducing the slurry viscosity to the required level.

[0003] Currently, when dispersing slurry, the powder and liquid in the slurry are initially mixed and then enter the shear zone, where the dispersion is completed. However, due to the high viscosity of the initially mixed slurry, it is easily obstructed during transportation, which may even cause blockages, affecting the transportation of the slurry and consequently affecting the subsequent dispersion of the slurry. Utility Model Content

[0004] To address the shortcomings of the existing production technology, the applicant provides a continuous disperser. By improving the structure of the disperser, the liquid can be fed in stages during the slurry dispersion process, thus avoiding the dispersion process being affected by the high viscosity of the slurry.

[0005] The technical solution adopted in this utility model is as follows: A continuous disperser includes: a housing, multiple stators, and multiple rotors. The stators and rotors are all installed inside the housing and are staggered. A shearing channel is formed between adjacent stators and rotors. The shearing channel is used to transport slurry and disperse the transported slurry. The stator is a hollow structure and is provided with a liquid inlet that penetrates the housing.

[0006] Therefore, by setting a liquid inlet on the stator to achieve stepped feeding of liquid in the slurry, compared with the existing method of powder and liquid entering the shear zone after preliminary mixing in the slurry, this method has a simple structure and is easy to operate. The liquid in the slurry can be quickly diffused throughout the shear channel through stepped feeding, avoiding high viscosity of the slurry due to uneven local mixing. This ensures that the slurry is always in a highly efficient shear state throughout the dispersion process, significantly improving the uniformity of slurry dispersion and effectively preventing slurry conveying obstruction or even blockage due to high slurry viscosity.

[0007] As a further improvement to the above technical solution: Multiple first oblique grooves are provided on both sides of the stator, and multiple second oblique grooves are provided on both sides of the rotor. The first and second oblique grooves are staggered in the radial direction. Therefore, during slurry dispersion, the slurry flows through the first oblique grooves on the stator and the second oblique grooves on the rotor. When the rotor rotates, the slurry flows under the centrifugal force generated by the rotor. When the slurry in the second oblique groove passes through the first oblique groove, it is injected at high speed from the second oblique groove into the first oblique groove. This high-speed jet is pushed back by the first oblique groove, thus generating strong turbulent rotation in the connecting area between the first and second oblique grooves. This prolongs the residence time of the slurry within the stator and rotor structure, thereby improving the dispersion effect and efficiency of the slurry. Furthermore, because the first and second oblique grooves are staggered in the radial direction, This design ensures that the entire geared stator-rotor structure has shearing channels in both the radial and axial directions. By increasing the number of shearing channels, the residence time of the slurry within the stator-rotor structure is further extended, thereby improving the dispersion effect and efficiency of the slurry. Simultaneously, by setting multiple first oblique cutting grooves and multiple second oblique cutting grooves, the number of times the slurry is sheared per unit time can be increased while reducing the height difference between the stator and rotor, further extending the residence time of the slurry within the stator-rotor structure and thus further improving the dispersion effect and efficiency of the slurry. It also reduces the volume occupied by the entire geared stator-rotor structure, thereby reducing the overall volume occupied by the disperser.

[0008] As a further improvement to the above technical solution: a first protrusion is formed between two adjacent first oblique grooves, and the angle between the plane A on the side of the first oblique groove away from the rotation direction and the radial plane B corresponding to plane A is . A second protrusion is formed between two adjacent second oblique grooves, and the angle between the plane C on the side of the second oblique groove relative to the first oblique groove and the radial plane D corresponding to the plane C is . Wherein: a shearing channel is formed between the first protrusion and the second protrusion.

The size gradually increases from the inside out; along the circumferential direction of the stator, multiple first oblique grooves are sequentially arranged, and the included angle corresponding to each first oblique groove is...

The purpose of equality is to ensure that the turbulence generated between the first and second oblique grooves is equal, thereby ensuring the consistency of slurry mixing; the included angle of the first oblique groove is [value missing] along the axial direction of the stator and along the slurry conveying direction. The purpose of gradually increasing the angle is to ensure that the slurry at the inlet of the shell is in a state where the powder and liquid are just mixed. At this state, the slurry viscosity is highest, and the included angle of the first oblique groove is relatively small. This ensures the flow of the slurry, and as the slurry continues to disperse, its viscosity is gradually reduced by the shearing action of the stator and rotor. The angle of the first oblique groove... Gradually increasing the size can change the flow direction of the slurry, so as to facilitate the turbulence generated between the first and second oblique grooves.

[0010] As a further improvement to the above technical solution: along the radial direction of the rotor, multiple second oblique grooves are formed, and the included angle of each second oblique groove is... The size gradually increases from the inside out; multiple second oblique grooves are sequentially arranged along the circumferential direction of the rotor, and the included angle corresponding to each second oblique groove is... Equal; along the axial direction of the rotor and along the slurry conveying direction, the included angle corresponding to each of the second oblique grooves. Gradually increasing; wherein: along the radial direction of the stator and the rotor, the first oblique groove and the second oblique groove are staggered, and the included angles corresponding to the staggered first oblique grooves are... The included angle corresponding to the second oblique groove It gradually increases from the inside out. Therefore, along the radial direction of the rotor, the included angle of the second oblique groove... The purpose of gradually increasing the inner angle is: A smaller size can improve the fluidity of the slurry; the outer angle... Reverse the slurry; along the circumferential direction of the rotor, the included angle of each second oblique groove. The purpose of equality is to ensure that the turbulence generated between the first and second oblique grooves is equal, thereby ensuring the consistency of slurry mixing; the included angle of the second oblique groove is [value missing] along the axial direction of the rotor and along the slurry conveying direction. The purpose of gradually increasing the angle is to ensure that the slurry at the inlet of the shell is in a state where the powder and liquid are just mixed. At this state, the slurry viscosity is highest, and the included angle of the second oblique cutting groove is relatively small. This ensures the flow of the slurry, and as the slurry continues to disperse, its viscosity is gradually reduced by the shearing action of the stator and rotor. The angle of the second oblique groove... Gradually increasing the size of the rotor can change the flow direction of the slurry, so as to generate turbulence between the first and second oblique grooves; when the inner rotor rotates, it pushes the slurry to the outside and shears the slurry through the shearing channel; when the outer rotor rotates, it can shear the slurry and push it into the first oblique groove at the same time, so as to generate turbulence.

[0011] As a further improvement to the above technical solution, it also includes: a driving component and a dispersing shaft, wherein the driving component is connected to the housing, the dispersing shaft is located inside the housing, and the driving end of the driving component is connected to the dispersing shaft, and the rotor is sleeved on the outside of the dispersing shaft.

[0012] As a further improvement to the above technical solution, it also includes an impeller, which is mounted on the outer circumferential surface of the dispersing shaft. Thus, the impeller can transport the slurry to the area where the shearing channel is located.

[0013] As a further improvement to the above technical solution: the included angle of the second oblique groove on the side near the feed inlet of the housing is... .

[0014] As a further improvement to the above technical solution: the included angle of the second oblique groove on the side near the feed inlet of the housing is... ;in: Therefore, when the rotor rotates, a siphon effect is generated, which makes the slurry enter more smoothly, and the larger included angle of the second oblique groove. It can generate greater extrusion pressure, which facilitates the mixing of powder and liquid upon initial contact, thereby further improving the dispersion effect and dispersion efficiency of the slurry.

[0015] As a further improvement to the above technical solution: a heat exchange channel is provided inside the stator, and an inlet and an outlet are respectively provided on the outer wall of the stator relative to the heat exchange channel. Thus, by injecting condensate into the heat exchange channel inside the stator, the heat generated during the slurry dispersion process can be dissipated; furthermore, the condensate directly contacts the slurry through the stator, thereby improving the heat exchange effect of the slurry dispersion process.

[0016] The beneficial effects of this utility model are as follows: This invention features a liquid inlet on the stator to enable tiered feeding of liquid in the slurry. Compared to existing methods where powder and liquid are initially mixed before entering the shearing zone, this method is simpler in structure and easier to operate. The tiered feeding allows the liquid to quickly diffuse throughout the shearing channel, preventing high viscosity due to uneven mixing in certain areas. This ensures the slurry remains in a highly efficient shearing state throughout the dispersion process, significantly improving the uniformity of slurry dispersion and effectively preventing slurry transport obstruction or even blockage due to high viscosity.

[0017] This utility model also has the following advantages: 1. In the dispersion of slurry, this invention utilizes a first oblique groove on the stator and a second oblique groove on the rotor. When the rotor rotates, the slurry flows under the centrifugal force generated by the rotor. When the slurry passes through the first oblique groove in the second oblique groove, it is injected at high speed into the first oblique groove. This high-speed jet is pushed back by the first oblique groove, generating strong turbulent rotation in the connecting area between the first and second oblique grooves. This prolongs the residence time of the slurry within the stator and rotor structure, thereby improving the dispersion effect and efficiency. Furthermore, because the first and second oblique grooves are staggered in the radial direction... This design ensures that the entire geared stator and rotor structure has shearing channels in both the radial and axial directions. By increasing the number of shearing channels, the residence time of the slurry within the stator and rotor structure is further extended, thereby improving the dispersion effect and efficiency of the slurry. Simultaneously, by setting multiple first oblique cutting grooves and multiple second oblique cutting grooves, the number of times the slurry is sheared per unit time can be increased while reducing the height difference between the stator and rotor, further extending the residence time of the slurry within the stator and rotor structure, thus further improving the dispersion effect and efficiency of the slurry. It also reduces the volume occupied by the entire geared stator and rotor structure, thereby reducing the overall volume occupied by the disperser.

[0018] 2. This invention generates a siphon effect when the rotor rotates, making the slurry flow more smoothly, while the larger included angle of the second oblique groove... It can generate greater extrusion pressure, which facilitates the mixing of powder and liquid upon initial contact, thereby further improving the dispersion effect and dispersion efficiency of the slurry.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] Example 1: like Figures 1 to 7As shown, a continuous disperser includes: a housing 1, multiple stators 2 and multiple rotors 3. The stators 2 and rotors 3 are all installed inside the housing 1, and the stators 2 and rotors 3 are staggered. A shearing channel 4 is formed between adjacent stators 2 and rotors 3. The shearing channel 4 is used to transport slurry and disperse the transported slurry. The stator 2 is a hollow structure and is provided with a liquid inlet 201 that penetrates the housing 1. Therefore, by setting a liquid inlet 201 on the stator 2, the liquid in the slurry is fed in stages. Compared with the existing method where the powder and liquid in the slurry are initially mixed before entering the shearing zone, this method is simple in structure and easy to operate. The liquid in the slurry is fed in stages so that the liquid can quickly diffuse to the entire shearing channel 4, avoiding high viscosity of the slurry due to uneven local mixing. This ensures that the slurry is always in a highly efficient shearing state throughout the dispersion process, significantly improving the uniformity of the slurry dispersion operation and effectively preventing slurry conveying from being obstructed or even blocked due to high slurry viscosity.

[0023] In other words, after the powder and liquid in the slurry are initially mixed, the slurry has a high viscosity. If it is directly introduced into the shear channel for dispersion, the high viscosity of the slurry will easily cause obstruction or even blockage during transportation. However, this application achieves gradual mixing and dispersion of the powder and liquid by using the feed port on the stator 2 to feed the liquid in stages. This gradual dispersion method avoids the slurry's excessive viscosity from hindering its transportation or even causing blockage. At the same time, the step-by-step dispersion method avoids the high viscosity of the slurry due to uneven local mixing. As a result, the slurry is always in a highly efficient shear state throughout the dispersion process, significantly improving the uniformity of the slurry dispersion.

[0024] It should be noted that: several stators 2 near the feed inlet of the housing 1 are provided with liquid inlets 201. These liquid inlets 201 can be used not only to achieve step-by-step liquid feeding (i.e., the liquid required for the slurry), but also to add water (if the concentration of the slurry is high, water is added to dilute the slurry); however, the stators 2 located on the discharge outlet side of the housing 1 are not provided with liquid inlets 201. Since the slurry inside the stators 2 located on the discharge outlet side of the housing 1 flows out directly through the discharge outlet, if the stators 2 are provided with liquid inlets 201 and liquid is injected through these liquid inlets 201, the injected liquid cannot be mixed and dispersed with the slurry, which will affect the dispersion effect of the slurry.

[0025] In this embodiment, the stator 2 has multiple first oblique grooves 202 on both sides, and the rotor 3 has multiple second oblique grooves 301 on both sides. The first oblique grooves 202 and the second oblique grooves 301 are staggered in the radial direction. A first protrusion 203 is formed between two adjacent first oblique grooves 202. The angle between the plane A on the side of the first oblique groove 202 away from the rotation direction and the radial plane B corresponding to the plane A is . A second protrusion 302 is formed between two adjacent second oblique grooves 301. The angle between the plane C on the side of the second oblique groove 301 relative to the first oblique groove 202 and the radial plane D corresponding to the plane C is . Wherein, a shearing channel 4 is formed between the first protrusion 203 and the second protrusion 302. Therefore, during the dispersion of the slurry, through the first oblique groove 202 opened in the stator 2 and the second oblique groove 301 opened in the rotor 3, when the rotor 3 rotates, the slurry flows under the action of centrifugal force generated by the rotor 3. When the slurry in the second oblique groove 301 passes through the first oblique groove 202, the slurry is injected at high speed from the second oblique groove 301 into the first oblique groove 202. This high-speed jet is pushed back by the first oblique groove 202, thereby generating strong rotating turbulence in the connecting area between the first oblique groove 202 and the second oblique groove 301. This prolongs the residence time of the slurry within the stator and rotor 3 structure, thereby improving the dispersion effect and dispersion efficiency of the slurry. Furthermore, due to the first oblique groove 202 and the second oblique groove 301... The staggered arrangement in the radial direction ensures that the entire geared stator and rotor 3 structure has shearing channels 4 in both the radial and axial directions. By increasing the number of shearing channels 4, the residence time of the slurry within the stator and rotor 3 structure is further extended, thereby improving the dispersion effect and efficiency of the slurry. Simultaneously, by setting multiple first oblique cutting grooves 202 and multiple second oblique cutting grooves 301, the number of times the slurry is sheared per unit time can be increased while reducing the height difference between the stator 2 and rotor 3, further extending the residence time of the slurry within the stator and rotor 3 structure, thereby further improving the dispersion effect and efficiency of the slurry. It also reduces the volume occupied by the entire geared stator and rotor 3 structure, thus reducing the overall volume occupied by the disperser.

[0026] It should be noted that: I. For example Figure 4 As shown, plane A is the line containing line ab, and plane B is the line containing line ao. The included angle is... It is represented as the angle between lines ab and ao; II. Figure 6 As shown, rotor 3 rotates clockwise. Plane C is the line containing line cd (plane C is chosen as the reference plane because it is the force-bearing surface of the slurry during the clockwise rotation of rotor 3), and plane D is the line containing co. The included angle is... It is represented as the angle between line cd and line co.

[0027] In this embodiment, multiple first oblique grooves 202 are formed along the radial direction of the stator 2, and the included angle of each first oblique groove 202 is... The size gradually increases from the inside out; along the circumferential direction of the stator 2, multiple first oblique grooves 202 are sequentially arranged, and the included angle corresponding to each first oblique groove 202 is... Equal; along the axial direction of stator 2 and along the slurry conveying direction, the included angle corresponding to each first oblique groove 202 The angle gradually increases; multiple second oblique grooves 301 are formed along the radial direction of rotor 3, and the included angle of each second oblique groove 301 is...

The included angle corresponding to the second oblique groove 301 It gradually increases from the inside out. Therefore, along the radial direction of stator 2, the included angle of the first oblique groove 202... The purpose of gradually increasing the inner angle is: A smaller size can improve the fluidity of the slurry; the outer angle... The larger size will not obstruct the slurry and can create turbulence between it and the second oblique groove 301; along the circumferential direction of the stator 2, the included angle of each first oblique groove 202 is... The purpose of equality is to ensure that the turbulence generated between the first oblique groove 202 and the second oblique groove 301 is equal, thereby ensuring the consistency of slurry mixing; along the axial direction of the stator 2 and along the slurry conveying direction, the included angle of the first oblique groove 202 is... The purpose of gradually increasing the angle α is as follows: the slurry at the feed inlet of shell 1 is in a state where the powder and liquid are just mixed. At this state, the slurry viscosity is highest, and a smaller angle α of the first oblique groove 202 ensures slurry flow. As the slurry continues to disperse, its viscosity is gradually reduced by the shearing action of the stator 2 and rotor 3, and the angle α of the first oblique groove 202... Gradually increasing the angle can change the flow direction of the slurry, so as to facilitate the turbulence generated between the first oblique groove 202 and the second oblique groove 301; along the radial direction of the rotor 3, the included angle of the second oblique groove 301 The purpose of gradually increasing the inner angle is: A smaller size can improve the fluidity of the slurry; the outer angle... Reverse the slurry; along the circumferential direction of rotor 3, each second oblique groove 301 has an included angle. The purpose of equality is to ensure that the turbulence generated between the first oblique groove 202 and the second oblique groove 301 is equal, thereby ensuring the consistency of slurry mixing; along the axial direction of the rotor 3 and along the slurry conveying direction, the included angle of the second oblique groove 301 is... The purpose of gradually increasing the angle is to ensure that the slurry at the feed inlet of shell 1 is in a state where the powder and liquid are just mixed. In this state, the slurry viscosity is the highest, and the included angle of the second oblique groove 301 is relatively small. This ensures the flow of the slurry, and as the slurry continues to disperse, its viscosity is gradually reduced by the shearing action of the stator 2 and rotor 3. The included angle of the second oblique groove 301... Gradually increasing the size can change the flow direction of the slurry, so as to generate turbulence between the first oblique groove 202 and the second oblique groove 301; when the inner rotor 3 rotates, it pushes the slurry to the outside and shears the slurry through the shear channel 4; when the outer rotor 3 rotates, it can shear the slurry and push the slurry into the first oblique groove 202 at the same time, so as to generate turbulence.

[0028] In this embodiment, the system further includes a drive component 5, a dispersing shaft 6, and an impeller 7. The drive component 5 is connected to the housing 1, the dispersing shaft 6 is located inside the housing 1, and the drive end of the drive component 5 is connected to the dispersing shaft 6. The rotor 3 is sleeved on the outside of the dispersing shaft 6, and the impeller 7 is mounted on the outer circumferential surface of the dispersing shaft 6. Thus, the impeller 7 can transport the slurry to the area where the shearing channel 4 is located.

[0029] Specifically, the driving end of the driving component 5 is connected to the dispersing shaft 6 via a belt gear set or two gears.

[0030] For example: drive component 5.

[0031] In this embodiment, the included angle of the second oblique groove 301 near the feed inlet of the housing 1 is . .

[0032] In this embodiment, a heat exchange channel 204 is provided inside the stator 2, and a water inlet 205 and a water outlet 206 are respectively provided on the outer wall of the stator 2 relative to the heat exchange channel 204. Thus, by injecting condensate into the heat exchange channel 204 inside the stator 2, the heat generated during the slurry dispersion process can be dissipated. Furthermore, the condensate directly contacts the slurry through the stator 2, thereby improving the heat exchange effect of the slurry dispersion process.

[0033] Example 2: The dispersion process of the slurry of this utility model is as follows: First, the powder in the slurry is injected into the disperser through the feed inlet, and the liquid in the slurry is injected into the disperser through the liquid inlet 201 to achieve stepwise feeding of the liquid; finally, the drive component 5 is started, and the drive component 5 drives the dispersion shaft 6 to rotate, so that the impeller 7 rotates, thereby causing the slurry to flow from the feed inlet to the discharge outlet. The dispersion shaft 6 can also drive the rotor 3 to rotate, so that during the process of the slurry flowing from the feed inlet to the discharge outlet (i.e., flowing in the shearing channel 4), the slurry is dispersed by the cooperation of the first oblique cutting groove 202 and the second oblique cutting groove 301 to break up the agglomerates in the slurry. The dispersed slurry is discharged through the discharge outlet.

[0034] like Figure 8 As shown, the difference from Embodiment 1 is that the included angle of the second oblique groove 301 on the side near the feed inlet of the housing 1 is... ;in: Therefore, when rotor 3 rotates, a siphon effect is generated, which makes the slurry enter more smoothly, and the included angle of the larger second oblique groove 301 is also increased. It can generate greater extrusion pressure, which facilitates the mixing of powder and liquid upon initial contact, thereby further improving the dispersion effect and dispersion efficiency of the slurry.

[0035] In summary, this utility model, by providing a liquid inlet 201 on the stator 2, enables the stepwise feeding of liquid in the slurry. Compared to the existing method where the powder and liquid in the slurry are initially mixed before entering the shearing zone, this method has a simpler structure and is easier to operate. The stepwise feeding of liquid in the slurry allows the liquid to quickly diffuse throughout the entire shearing channel 4, avoiding high viscosity of the slurry due to uneven local mixing. This ensures that the slurry remains in a highly efficient shearing state throughout the entire dispersion process, significantly improving the uniformity of slurry dispersion and effectively preventing slurry transport obstruction or even blockage due to high viscosity.
