[0002] In the production process of cathode materials, the internal structure of the mixing equipment directly affects the uniformity and effectiveness of mixing the cathode material and the coating agent. Current mixing equipment typically uses stirring blades to mix materials. However, with the continuous innovation and diversification of cathode materials, existing mixing equipment is unable to meet the mixing requirements, especially for new materials, and may fail to achieve the required uniformity, ultimately leading to abnormalities in finished product capacity, DC internal resistance, and cycle performance.

[0003] In other words, existing mixing equipment suffers from poor mixing consistency.

[0004] It should be noted that the information provided in this section is merely background information relevant to this disclosure and is not necessarily prior art. Utility Model Content

[0005] The main objective of this invention is to provide a mixing device to solve the problem of poor mixing consistency in existing mixing devices.

[0006] To achieve the above objectives, this utility model provides a mixing device, including: a mixing bin, stirring blades, and a drive mechanism.

[0012] Furthermore, the connector includes a connecting body and a screw. The connecting body is detachably connected to the spoiler. The end of the connecting body away from the spoiler is threadedly connected to the screw. The screw is detachably connected to the top wall of the mixing chamber. The mixing chamber includes a central shaft that extends from the center of the top wall to the center of the bottom wall of the mixing chamber. The angle between the spoiler and the extension direction of the central shaft is less than 10°.

[0013] Furthermore, the connector only includes a connecting body, which is detachably connected to the side wall. The mixing chamber includes a central shaft that extends from the center of the top wall of the mixing chamber to the center of the bottom wall of the mixing chamber.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0035] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0036] like Figures 1 to 12 As shown, the mixing equipment includes a mixing bin 10, a stirring blade 40, a drive mechanism 50, and a turbulence assembly 20. The stirring blade 40 is installed inside the mixing bin 10, and the drive mechanism 50 is driven to rotate the stirring blade 40. The turbulence assembly 20 is installed inside the mixing bin 10 and includes a turbulence plate 21. The turbulence plate 21 is located inside the mixing bin 10, and the inner wall of the turbulence plate 21 is spaced apart from the side wall 14 of the mixing bin 10.

[0037] The mixing chamber 10 has a cavity structure and includes a mixing space 11 for mixing materials. A stirring blade 40 is installed inside the mixing chamber 10. The drive mechanism 50 can be a motor, and its drive end is connected to the stirring blade 40 to drive the stirring blade 40 to rotate.

[0038] In some optional embodiments, the mixing bin 10 includes a mixing space 11 for mixing materials, and a baffle 21 is embedded in the mixing space 11. In the mixing space 11, a baffle assembly 20 is connected to the mixing bin 10, and a groove is formed on the side wall 14. The baffle 21 is inserted into the groove, and the side wall 14 of the baffle 21 at least partially protrudes outside the groove so that the inner wall of the baffle 21 and the side wall 14 are kept at a certain distance.

[0039] It should be noted that the inner wall of the baffle 21 refers to the surface of the baffle 21 away from the side wall 14 of the mixing bin 10, that is, the inner wall of the baffle 21 is the surface closer to the central axis 15 of the mixing bin 10. In other words, the inner wall of the baffle 21 at least partially protrudes outside the groove. It is understood that in some embodiments, the inner wall of the baffle 21 has an arc-shaped structure, with the arc-shaped concave surface of the baffle 21 facing the central axis 15 of the mixing bin 10.

[0040] In this way, by installing stirring blades 40 in the mixing chamber 10 and driving the driving mechanism 50 to drive the stirring blades 40 to rotate, the stirring blades 40 can drive the materials in the mixing chamber 10 to mix. Furthermore, by installing a turbulence assembly 20 in the mixing chamber 10 and setting the inner wall and side wall 14 of the turbulence plate 21 in the turbulence assembly 20 to be spaced apart, turbulence or eddies are generated when the materials are mixed, which promotes more uniform mixing of the positive electrode material and the coating agent, improves the consistency of the mixed materials, and thus optimizes the mixing effect of the materials.

[0041] The minimum distance between the inner wall and side wall 14 of the baffle 21 is 1mm to 30mm. By setting the minimum distance between the inner wall and side wall 14 of the baffle 21 to between 1mm and 30mm, the baffle 21 can generate appropriate shearing and impact forces on the airflow, ensuring that the airflow shearing force is sufficient to disperse materials with high viscosity or easy agglomeration, thereby promoting material dispersion and preventing excessive airflow shearing force from causing normal particles to break and form a large number of micro-particles. When the minimum distance between the inner wall and side wall 14 of the baffle 21 is less than 1mm, the baffle 21's turbulence effect on the airflow is weak and insufficient to disperse materials with high viscosity or easy agglomeration. When the minimum distance between the inner wall and side wall 14 of the baffle 21 is greater than 30mm, the baffle 21's turbulence effect on the airflow is too great, the airflow shearing force is too strong, and a large number of normal particles break and form micro-particles.

[0042] The minimum distance between the inner wall of the spoiler 21 and the side wall 14 can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 13mm, 15mm, 18mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 27mm, 30mm or within any two of the above values.

[0043] Preferably, the minimum distance between the inner wall of the spoiler 21 and the side wall 14 can be 5mm to 20mm.

[0044] like Figure 1 and Figure 2 As shown, the turbulence assembly 20 also includes a connector, which is detachably connected to the mixing chamber 10. The turbulence plate 21 includes a first sliding structure 22, and the connector includes a second sliding structure 25. The first sliding structure 22 and the second sliding structure 25 are slidably connected. The turbulence assembly 20 includes a turbulence plate 21 and a connector, which can be detachably connected to the mixing chamber 10. The first sliding structure 22 on the turbulence plate 21 and the second sliding structure 25 on the connector are matched, so that the second sliding structure 25 can be engaged with the first sliding structure 22 and the connector can slide relative to the turbulence plate 21. This allows for convenient adjustment of the distance between the turbulence plate 21 and the side wall 14, meeting the mixing requirements of different materials and reducing the phenomenon of local over-mixing or under-mixing of materials. This arrangement allows for quick changes in the position of the turbulence plate 21, avoiding frequent replacement of the turbulence plate 21 and reducing production and maintenance costs.

[0045] Optionally, one of the first sliding structure 22 and the second sliding structure 25 is a guide rail, and the other of the first sliding structure 22 and the second sliding structure 25 is a sliding member, with the sliding member at least partially located within the guide rail. The sliding member being at least partially located within the guide rail allows the sliding member and the guide rail to cooperate with each other, reducing the risk of them disengaging and thus ensuring the stability of their sliding motion.

[0046] In some optional embodiments, the first sliding structure 22 is a sliding member, and the second sliding structure 25 is a guide rail. The guide rail is a groove-shaped structure, and the sliding member is a long strip-shaped structure slidably disposed within the groove-shaped structure to change its relative position to the groove-shaped structure. Furthermore, the length of the sliding member is greater than the length of the guide rail, and a portion of the sliding member is located within the groove-shaped structure of the guide rail, which can fix the position of the connecting member. This ensures that the sliding member and the guide rail remain connected when the position of the spoiler 21 relative to the connecting member is changed. The distance between the spoiler 21 and the sidewall 14 is adjusted by regulating the relative position between the sliding member and the guide rail to accommodate the mixing of different materials.

[0047] Optionally, the connector is detachably connected to the mixing hopper 10, for example, the connector may be threaded, bolted, or keyed to the mixing hopper 10. In some embodiments, the connector may be detachably connected to the side wall 14 or the top wall 12.

[0048] like Figure 1 and Figure 2 As shown, the spoiler 21 includes multiple first connecting holes 23, and the connector includes multiple fasteners 34, which are connected to the multiple first connecting holes 23. The first connecting holes 23 and the fasteners 34 can fix the relative position of the spoiler 21 and the connector after position adjustment, ensuring the mobility of the spoiler assembly 20.

[0049] In some optional embodiments, to adjust the spacing between the spoiler 21 and the sidewall 14, the spoiler 21 is provided with a plurality of first connecting holes 23. The first connecting holes 23 are located on the sliding member of the spoiler 21, and a plurality of fasteners 34 of the connector can be connected to the first connecting holes 23 to fix the spoiler 21 to the connector. This arrangement ensures that the spoiler 21 will not fall off or deform due to material impact during high-speed mixing, and also facilitates the adjustment of the position of the spoiler 21, reducing the risk of foreign objects and cost associated with replacing different types of spoilers 21. Preferably, the fasteners 34 can be bolts.

[0050] It should be noted that the number of first connecting holes 23 on the spoiler 21 is greater than the number of fasteners 34 on the connector. When the position of the spoiler 21 is changed, the fasteners 34 are connected to different first connecting holes 23. In other words, the position of the spoiler 21 can be changed by connecting the fasteners 34 to different first connecting holes 23.

[0051] In some optional embodiments, the first connecting hole 23 can be an elongated hole, which serves as a guide groove. When the position of the spoiler 21 is changed, the fastener 34 is allowed to slide linearly along the length of the elongated hole. After the position of the spoiler 21 is determined, the relative position of the fastener 34 and the elongated hole is fixed, thereby ensuring a stable connection between the spoiler 21 and the connector.

[0052] In some alternative embodiments, the first connection hole 23 is disposed on the first sliding structure 22.

[0053] In some alternative embodiments, please refer to Figure 1 and Figure 2 The connector includes a connecting body 24 and a plurality of fasteners 34. The connecting body 24 includes a plurality of second connecting holes 26. The fasteners 34 pass through the first connecting hole 23 and the second connecting hole 26 to fix the spoiler 21 to the connecting body 24 together.

[0054] Optionally, the fastener 34 and the connecting body 24 can be an integral structure; or the fastener 34 and the connecting body 24 can be separate structures.

[0055] In some optional embodiments, the connector includes a connecting body 24 and a screw 31. The connecting body 24 is detachably connected to the baffle 21, and the end of the connecting body 24 away from the baffle 21 is threadedly connected to the screw 31. The screw 31 is detachably connected to the top wall 12 of the mixing chamber 10. This configuration allows the height of the baffle 21 in the mixing space 11 to be adjusted by changing the position of the screw 31, thereby adapting to the mixing requirements of different materials.

[0056] In some optional embodiments, the baffle assembly 20 is detachably connected to the top wall 12. The connector includes a connecting body 24, multiple fasteners 34, and a screw 31. The connecting body 24 includes multiple second connecting holes 26, and the fasteners 34 pass through the first connecting holes 23 and the second connecting holes 26. After the multiple second connecting holes 26 are aligned with the first connecting holes 23, the fasteners 34 sequentially connect the second connecting holes 26 and the first connecting holes 23, thereby positioning the baffle 21 at the required position. At the same time, the connecting body 24 and the baffle 21 can also be detachably connected. After one end of the connecting body 24 is positioned with the baffle 21, the end of the connecting body 24 away from the baffle 21 is connected to the screw 31 by a thread. At this time, the relative positions of the baffle 21, the connecting body 24, and the screw 31 in the mixing chamber 10 are stable, which can resist the impact force generated during the material mixing process while changing the material flow trajectory, thereby improving the uniformity and consistency of the mixing. Along the direction away from the baffle 21, the screw 31 is screwed into the pre-drilled hole 30, fixing plate 32, and gasket 33 on the top wall 12 through its surface threads, thus sealing the top wall 12 and fixing the screw 31. During the mixing process, the position of the entire baffle assembly 20 relative to the top wall 12, fixing plate 32, and gasket 33 is relatively fixed. When adjustments are needed according to different materials, the relative position and angle of the baffle 21 can be adjusted by rotating the screw 31, ensuring that the baffle 21 can be flexibly adjusted without compromising the integrity of the mixing equipment. The screw 31 and the top wall 12 of the mixing chamber 10 can be detachably connected, thus allowing the same mixing chamber 10 to adapt to the characteristics of different materials.

[0057] In some optional embodiments, the first connecting hole 23 and the second connecting hole 26 can be elongated holes, with the length of the elongated hole of the first connecting hole 23 being greater than the length of the elongated hole of the second connecting hole 26 along its length direction. When the position of the spoiler 21 is changed, the elongated hole acts as a guide groove, allowing the fastener 34 to slide linearly along its length direction. This allows the fastener 34 to pass through the elongated holes of the second connecting hole 26 and the first connecting hole 23 in sequence, thus providing a fixing effect. After the position of the spoiler 21 is determined, the relative positions of the fastener 34 with the elongated holes of the second connecting hole 26 and the first connecting hole 23 are fixed, thereby ensuring a stable connection between the spoiler 21 and the connector.

[0058] In one specific embodiment (not shown), there is one first connecting hole 23 and one fastener 34. By adjusting the position of the fastener 34 relative to the first connecting hole 23, the relative position of the spoiler 21 is changed. In another specific embodiment, as shown... Figure 1 As shown, there are multiple first connecting holes 23 and multiple fasteners 34. The multiple fasteners 34 are connected to the second connecting hole 26 and the first connecting hole 23 in sequence to realize the positioning of the spoiler 21 at the required position.

[0059] It should be noted that the first connecting hole 23 and the second connecting hole 26 can also be threaded holes.

[0060] In some alternative embodiments, the connecting body 24 is detachably connected to the sidewall 14. The connector includes the connecting body 24 and a plurality of fasteners 34. The fasteners 34 are connected to the first connecting hole 23 and are located on both sides of the connecting body 24, abutting against the edge of the connecting body 24. After the fasteners 34 enter the first connecting hole 23 of the spoiler 21, the fasteners 34 are located on both sides of the connecting body 24 and the head of the fasteners 34 can abut against the edge of the connecting body 24 to limit the position of the connecting body 24 on the spoiler 21 and ensure the stability of the relative position between the connecting body 24 and the spoiler 21. A plurality of sidewall fixing holes 36 are provided at the end of the connecting body 24 away from the spoiler 21. The sidewall fixing holes 36 are matched in size and number with the side holes 37 on the sidewall 14 of the mixing bin 10 so that the mounting parts can pass through the side holes 37 and the sidewall fixing holes 36 sequentially from the outside of the mixing bin 10. Multiple sidewall fixing holes 36 and matching side holes 37 are provided to ensure that the spoiler 21 maintains its shape and position even under harsh environments of high-speed rotation and strong material impact, effectively avoiding wear and the generation of metal foreign objects, and improving production safety and product purity. Preferably, the mounting component can be a bolt.

[0061] It should be noted that the mixing chamber 10 includes a central shaft 15, which extends from the center of the top wall 12 of the mixing chamber 10 to the center of the bottom wall 13 of the mixing chamber 10. The baffle 21 and the extending direction of the central shaft 15 can form a certain angle, thereby achieving a better mixing effect for different material types. When the baffle assembly 20 is detachably connected to the top wall 12, the angle between the baffle 21 and the extending direction of the central shaft 15 is less than 10°. That is to say, by setting the direction or shape of the connector, the baffle 21 can be tilted within 10° relative to the extending direction of the central shaft 15.

[0062] In some embodiments, the angle between the spoiler 21 and the extending direction of the central axis 15 can be 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, or any two of the above values. Preferably, the angle between the spoiler 21 and the extending direction of the central axis 15 can be between 1° and 6°.

[0063] In some embodiments, the angle between the spoiler 21 and the extending direction of the central axis 15 is 150° to 180°. That is, by changing the shape of the connecting body 24, the spoiler 21 can have an angle of 150° to 180° relative to the extending direction of the central axis 15.

[0064] The angle between the spoiler 21 and the extending direction of the central axis 15 can be 150°, 152°, 155°, 158°, 160°, 163°, 165°, 168°, 172°, 175°, 177°, 180°, or any combination of two of the above values. Preferably, the angle between the spoiler 21 and the extending direction of the central axis 15 can be 150° or 165°.

[0065] After the spoiler 21 forms the aforementioned angle with the extension direction of the central axis 15, it can provide different tangential forces to the material in the extension direction of the central axis 15. It can be understood that the material farther away from the central axis 15 receives a smaller shearing force. After the connector provides a certain angle, the spoiler 21 is inclined along the extension direction of the central axis 15, thereby satisfying the control of the shearing force of the spoiler 21 in the extension direction of the central axis 15.

[0066] To adapt to different fluid dynamic requirements and spatial layouts within the mixing equipment, the baffle 21 can optionally be a straight plate or a curved plate. The angle formed between the baffle 21 and the adjacent side perpendicular to the first sliding structure 22 is between 0° and 180°. When the angle is 0° or 180°, the baffle 21 is a straight plate; when the angle is greater than 0° and less than 180°, the baffle 21 is a curved plate with a certain curvature. That is, the baffle 21 can be a straight plate to ensure that the material can be evenly dispersed when entering the mixing space 11 of the mixing bin 10, or it can be a curved plate with a curvature to better guide and control the material flow path, thereby reducing mixing dead zones and improving mixing efficiency.

[0067] It should be noted that the curved plate can be a circular arc plate or a curved plate made up of multiple arc-shaped plates spliced ​​together.

[0068] Specifically, the spoiler 21 is made of stainless steel, and its surface is coated with a nano-ceramic or polytetrafluoroethylene (PTFE) coating. The stainless steel spoiler 21, coated with a non-stick coating such as nano-ceramic or PTFE, provides good corrosion resistance and strength. The nano-ceramic coating further enhances the spoiler 21's wear resistance, high-temperature resistance, and corrosion resistance. The PTFE coating, due to its low coefficient of friction and excellent chemical stability, effectively prevents material adhesion to the spoiler 21 surface, reducing the generation of foreign matter and ensuring the cleanliness and purity of the mixing process. Furthermore, the non-stick coating avoids the downtime and labor costs associated with frequent spoiler 21 maintenance, while also reducing the risk of equipment damage.

[0069] like Figure 3 and Figure 4 As shown, the top wall 12 includes at least one inlet 35 to allow material to enter the mixing space 11, and the bottom wall 13 includes at least one outlet to allow the mixed material to be discharged from the mixing space 11. At least one of the reserved holes 30 in the top wall 12 of the mixing device can serve as an inlet 35, acting as an entrance for the material and ensuring that the material can smoothly enter the mixing space 11 of the mixing device. After the material enters the mixing space 11, the drive mechanism 50 is driven to connect with the stirring blade 40, allowing the drive mechanism 50 to drive the stirring blade 40 to rotate. The baffle 21 simultaneously interferes with the flow of the material, optimizing the mixing effect. After the material is mixed, the rotating stirring blade 40 drives the material to flow out from at least one outlet of the bottom wall 13. It should be noted that before mixing begins, the inlet 35 of the top wall 12 is opened. During the mixing process, both the inlet 35 of the top wall 12 and the outlet of the bottom wall 13 are sealed. After mixing, the outlet of the bottom wall 13 is opened to allow the mixed material to flow out.

[0070] Example 1

[0071] like Figures 1 to 4 The mixing equipment of Embodiment 1 is described in the figure. The turbulence assembly 20 of the mixing equipment is detachably connected to the top wall 12 of the mixing chamber 10. The turbulence assembly 20 includes a turbulence plate 21, a connecting body 24, a fastener 34, and a screw 31. The relative positions of the sliding part of the turbulence plate 21 and the guide rail of the connecting body 24 are fixed by the fastener 34 after adjustment. The end of the connecting body 24 away from the turbulence plate 21 is threadedly connected to the screw 31. The screw 31 passes sequentially through the reserved hole 30 near the edge of the top wall 12, the fixing plate 32, and the gasket 33. By rotating the screw 31, the turbulence plate 21 is moved or its angle is adjusted. The turbulence plate 21 is a straight plate, and the cross-section of the surface where the material impacts the turbulence plate 21 is rectangular.

[0072] In Example 1, the baffle 21 is in the form of a straight plate. When the material flows clockwise and comes into contact with it, the tangential direction formed forms a 90° angle with the baffle 21. This can promote the material to change direction after contacting the baffle 21, thereby breaking the original flow pattern, promoting the mutual interleaving and collision of the positive electrode material and the coating agent, and enhancing the mixing effect.

[0073] Example 2

[0074] The mixing equipment in Embodiment 2 is not shown. The difference from Embodiment 1 is that when the material impacts and contacts the baffle 21, the angle between the tangential direction of the material flow and the baffle 21 is 120°.

[0075] In Embodiment 2, the impact force of the material on the baffle 21 is reduced, the flow path of the material is changed more gently, the material can be more evenly distributed during the mixing process, the local high-speed shearing action is reduced, which helps to maintain the original shape and performance of the material, and also helps to extend the service life of the baffle 21 and the entire mixing equipment, and reduce maintenance costs.

[0076] Example 3

[0077] like Figure 5 The image shows a mixing device according to Embodiment 3. The difference from Embodiment 1 is that the baffle 21 has a curved shape.

[0078] In embodiment three, the guide rail of the connecting body 24 and the sliding component of the spoiler 21 can be slidably connected, and the fastener 34 and the connecting body 24 are an integral structure. The curved spoiler 21 is suitable for specific mixed materials, promoting more uniform mixing with a specific flow trajectory.

[0079] Example 4

[0080] like Figures 6 to 9The image shows a mixing device according to Embodiment 4. The difference from Embodiment 1 is that the turbulence-disrupting component 20 of the mixing device is detachably connected to the side wall 14 of the mixing chamber 10. The turbulence-disrupting component 20 includes a turbulence plate 21, a connecting body 24, and fasteners 34. The connecting body 24 is connected to the turbulence plate 21 by the fasteners 34. The end of the connecting body 24 away from the turbulence plate 21 includes two side wall fixing holes 36, which are connected to the corresponding side holes 37 on the side wall 14 via mounting parts. The turbulence plate 21 is a curved plate with an arc.

[0081] In embodiment four, fasteners 34 connect the two side wall fixing holes 36 to the corresponding side holes 37 on the mixing chamber 10. This simplifies the installation process of the baffle 21 while ensuring its stability during mixing, preventing displacement or damage caused by violent material flow and impact. This improves the overall durability and safety of the mixing equipment. Furthermore, operators can flexibly adjust the relative positions of the guide rails and sliding parts according to actual mixing needs while ensuring the stability of the mixing equipment, thereby adjusting the position and angle of the baffle 21 to achieve the best mixing effect.

[0082] Preferably, the sliding member is located in the middle of the surface of the spoiler 21 away from the impact of the material. This arrangement can enhance the structural strength of the spoiler 21, thereby meeting the impact force of the material on the spoiler 21.

[0083] It should be noted that the shape of the connecting body 24 can be adaptively changed according to the angle between the tangential direction of the material flow and the baffle 21.

[0084] Example 5

[0085] like Figure 10 The image shows a mixing device according to Embodiment 5. The difference from Embodiment 4 is that when the material impacts and contacts the baffle 21, the angle between the tangential direction of the material flow and the baffle 21 is 120°; the baffle 21 is a straight plate.

[0086] In Embodiment 5, the impact force of the material on the baffle 21 is reduced, the flow path of the material is changed more gently, the material can be more evenly distributed during the mixing process, the local high-speed shearing action is reduced, which helps to maintain the original shape and performance of the material, and also helps to extend the service life of the baffle 21 and the entire mixing equipment, and reduce maintenance costs.

[0087] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0088] By installing stirring blades 40 inside the mixing chamber 10 and driving the driving mechanism 50 to drive the stirring blades 40 to rotate, the stirring blades 40 can drive the materials inside the mixing chamber 10 to mix. Furthermore, by installing a turbulence assembly 20 inside the mixing chamber 10 and setting the inner wall and side wall 14 of the turbulence plate 21 in the turbulence assembly 20 to be spaced apart, turbulence or eddies are generated during the mixing of the materials, which promotes more uniform mixing of the positive electrode material and the coating agent, improves the consistency of the mixed materials, and thus optimizes the mixing effect of the materials.
