Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, and more specifically, to a mixing device. Background Technology

[0002] Currently, in dry electrode processes, the use of solvents is replaced by fiberizing and rolling the electrode raw materials into films, which has the advantages of low cost, energy saving, and environmental protection. However, the current fiberization process suffers from poor overall dispersion and mixing, resulting in problems such as low degree of fiberization, low film strength, and low yield. Utility Model Content

[0003] The main objective of this invention is to provide a mixing device to solve the problem of poor mixing effect in the existing electrode raw material fiberization mixing process.

[0004] To achieve the above objectives, according to one aspect of the present invention, a mixing device is provided, comprising: a base; a container for containing materials, the container being connected to the base and inclined relative to a horizontal plane; a stirring assembly, at least a portion of which is rotatably disposed within the container and used for stirring and mixing the materials within the container; and a dispersing assembly, at least a portion of which is rotatably disposed within the container, the axis of rotation of which is eccentrically disposed relative to the central axis of the container, the dispersing assembly being located below the central axis of the container, and the dispersing assembly being used for stirring and mixing the materials within the container.

[0005] Furthermore, the stirring assembly includes a stirring element and a stirring drive element that are driven together, and the dispersing assembly includes a dispersing element and a dispersing drive element that are driven together. The stirring drive element and the dispersing drive element are respectively provided and can drive the stirring element and the dispersing element to rotate in the same direction or in opposite directions respectively.

[0006] Furthermore, the dispersing assembly includes a dispersing element located within the container, and the stirring assembly includes a stirring element located within the container, with the dispersing element positioned above the stirring element and the lowest point of the dispersing element being higher than the lowest point of the stirring element.

[0007] Furthermore, the base includes a first seat and a second seat, the first seat is located above the second seat and is rotatably disposed relative to the second seat, the upper surface of the first seat is inclined, and the container is mounted on the upper surface of the first seat.

[0008] Furthermore, the mixing device also includes an angle adjustment component, which is connected to the second seat and driven to the first seat. The angle adjustment component drives the first seat to rotate up and down relative to the second seat to change the tilt angle of the upper surface of the first seat.

[0009] Furthermore, the stirring assembly includes: a stirring drive unit disposed on a base; and a stirring member, wherein the stirring shaft of the stirring drive unit extends into the container, the stirring member is disposed on the stirring shaft and rotates under the drive of the stirring shaft, the stirring member is located in the bottom region of the container, and the stirring member has a first flow channel for introducing a medium.

[0010] Furthermore, the stirring assembly includes: a stirring drive unit disposed on a base; and a stirring member, wherein the stirring shaft of the stirring drive unit extends into the container, the stirring member is disposed on the stirring shaft and rotates under the drive of the stirring shaft, the stirring member is located in the bottom region of the container, and the stirring member has a first flow channel for introducing a medium.

[0011] Furthermore, an eccentricity is formed between the rotation axis of the dispersing component and the central axis of the container, and the eccentricity is 0.1-0.6 times the diameter of the dispersing component.

[0012] Furthermore, the mixing device also includes a jacket disposed at the bottom and / or side of the container, the jacket having a second flow channel for introducing the medium.

[0013] Furthermore, the container has a discharge pipe that is connected to the interior of the container and is located on the bottom side of the container where the height is lower.

[0014] By applying the technical solution of this utility model, the container is tilted and an eccentric dispersion component is installed inside the container. The dispersion component works in conjunction with the stirring component to assist in mixing. Due to the tilt of the container, the material inside can slide downwards under its own gravity. Since the dispersion component is eccentrically positioned at the lower part of the container, the sliding material can enter the stirring range of the dispersion component. At this time, the dispersion component can drive this part of the material to mix and stir, thereby increasing the proportion of material participating in dispersion and shearing. Both the stirring component and the dispersion component can fully mix the material, effectively promoting the circulation of the material under the dual action of gravity and mechanical stirring. It has a better dispersion effect, especially for materials with large differences in specific gravity, achieving higher efficiency and dispersion uniformity, thereby improving the degree of fiberization, film strength, and yield.

[0022] To address the problem of poor mixing effect during the fiberization and mixing process of electrode raw materials in existing technologies, this invention provides a mixing device.

[0023] like Figure 1 The mixing device shown includes a base 10, a container 20 for containing materials, a stirring assembly 30, and a dispersing assembly 40. The container 20 is connected to the base 10 and is inclined relative to a horizontal plane. At least a portion of the stirring assembly 30 is rotatably disposed inside the container 20 and is used to stir and mix the materials inside the container 20. At least a portion of the dispersing assembly 40 is rotatably disposed inside the container 20, and the rotation axis of the dispersing assembly 40 is eccentrically disposed relative to the central axis of the container 20. The dispersing assembly 40 is located below the central axis of the container 20 and is used to stir and mix the materials inside the container 20.

[0024] In this embodiment, the container 20 is tilted, and an eccentric dispersion component 40 is installed inside the container 20. The dispersion component 40 works in conjunction with the stirring component 30 to assist in mixing. Because the container 20 is tilted, the material inside can slide downwards under its own gravity. Since the dispersion component 40 is eccentrically positioned at the lower part of the container 20, the sliding material can enter the stirring range of the dispersion component 40. At this point, the dispersion component 40 can drive this portion of material to mix and stir, resulting in a higher proportion of material participating in dispersion and shearing. Both the stirring component 30 and the dispersion component 40 can fully mix the material, effectively promoting the circulation of the material under the dual effects of gravity and mechanical stirring. This is particularly effective for materials with large differences in specific gravity, achieving higher efficiency and dispersion uniformity, thereby improving the degree of fiberization, film strength, and yield.

[0025] In this embodiment, the stirring assembly 30 includes a stirring drive and a stirring element 31. The stirring drive is mounted on the base 10 and can be a motor or other components. It can be directly mounted on the base 10 or indirectly mounted on the base 10 via an intermediate component. The output end of the stirring drive is provided with a stirring shaft, which serves as a transmission component and extends into the container 20. The stirring element 31 is mounted on the stirring shaft, and the stirring element 31 and the stirring shaft can be connected by a key or other structural means to achieve a transmission connection, allowing the stirring element 31 to rotate under the drive of the stirring shaft, thereby achieving the functions of stirring, shearing, and mixing the materials.

[0026] Similar to the structure of the stirring assembly 30 described above, the dispersing assembly 40 of this embodiment includes a dispersing drive and a dispersing component 41. The dispersing drive can be a motor or other components, and the output end of the dispersing drive is provided with a drive shaft. The function of the drive shaft is the same as that of the stirring shaft. The drive shaft also extends into the container 20. The stirring shaft, the drive shaft, and the central axis of the container 20 are arranged in a roughly parallel manner. The dispersing component 41 is mounted on the drive shaft and can rotate under the drive of the drive shaft, so that the dispersing assembly 40 can also achieve stirring, shearing, mixing and other functions.

[0027] In this embodiment, the stirring drive and the dispersing drive are set separately, without any necessary correlation between them. This allows them to drive the stirring component 31 and the dispersing component 41 to move independently, enabling the stirring component 31 and the dispersing component 41 to rotate in the same or opposite directions, or at the same or different speeds. This allows the dispersing component 40 and the stirring component 30 to perform their respective functions according to different needs. Of course, if necessary, the stirring drive and the dispersing drive can also use the same drive, which transmits power to the stirring component 31 and the dispersing component 41 through different transmission paths.

[0028] Because the rotation axis of the stirring component 31, the rotation axis of the dispersing component 41, and the central axis of the container 20 are arranged in parallel in this embodiment, and the central axis of the container 20 and the rotation axis of the stirring component 31 are aligned, the dispersing component 41 is located below the central axis of the container 20. It should be noted that "below the central axis" here refers to the side with the lower central axis height. Since the container 20 is tilted, its central axis is also tilted, resulting in an upper and lower side. The upper side is... Figure 1 The dispersion element 41 is located on the upper left side of the central axis and the lower right side, so that the dispersion element 41 is located on the lower side of the container 20, which allows the dispersion element 41 to stir and mix the material that has fallen to the lower side of the container 20 by gravity.

[0029] In this embodiment, the dispersing component 41 is disposed above the stirring component 31, and the lowest point of the dispersing component 41 is higher than the lowest point of the stirring component 31. In this embodiment, the stirring component 31 is disposed in the bottom region of the container 20, while the dispersing component 41 is disposed in the middle region and / or top region of the container 20. In this way, the stirring component 31 and the dispersing component 41 can stir different positions along the axial direction respectively, thereby improving the mixing effect.

[0030] Optionally, the specific number of stirring components 31 and dispersing components 41 can be adjusted as needed. In this embodiment, one stirring component 31 is provided, and the gap between the stirring component 31 and the inner wall of the container 20 is preferably 2-16mm, which can cover a large stirring range without collision or interference with the container 20. As for the dispersing components 41, this embodiment provides multiple dispersing components 41, and each dispersing component 41 is spaced apart along the axial direction of the drive shaft, so that the dispersing components 41 form a multi-layer arrangement, which improves the dispersion range in the height direction and the stirring effect.

[0031] Because the rotation axis of the dispersing member 41 is eccentrically positioned relative to the central axis of the container 20, an eccentricity is formed between them. This eccentricity is preferably 0.1-0.6 times the diameter of the dispersing member 41, thereby increasing the proportion of material being sheared and improving efficiency. Preferably, in this embodiment, the dispersing member 41 employs pin teeth, which can prevent damage to the material caused by high-speed shearing.

[0032] In this embodiment, the base 10 includes a first base 11 and a second base 12. The first base 11 is located above the second base 12 and is rotatably arranged relative to the second base 12. In this embodiment, one side of the first base 11 and the second base 12 are connected by a pivot, hinge, or other structural form to create a rotatable fit. Thus, the first base 11 can rotate up and down around the pivot, resulting in an inclined upper surface. The container 20 is then mounted on the upper surface of the first base 11, naturally resulting in an inclined placement of the container 20 as well. Alternatively, besides the above arrangement, the interior of the container 20 can be directly designed as an inclined cavity, where the bottom surface of the container 20 is horizontal, and the axis of its cavity is inclined to the bottom surface.

[0033] In this embodiment, the mixing device further includes an angle adjustment component 50. The angle adjustment component 50 is connected to the second seat 12 and drivenly connected to the first seat 11. The angle adjustment component 50 can drive the first seat 11 to rotate up and down relative to the second seat 12, thereby changing the tilt angle of the first seat 11 relative to the second seat 12 under the drive of the angle adjustment component 50. This changes the tilt angle of the upper surface of the first seat 11, thus changing the tilt angle of the container 20 and achieving adjustment of the tilt angle of the container 20. In use, the tilt angle of the container 20 can be adjusted according to different material types, so that the tilt angle of the container 20 is related to the material type. This ensures that different materials can stably slide onto one side of the container 20, thereby guaranteeing the dispersion and mixing effect and improving adaptability. The specific structure of the angle adjustment component 50 can be set as needed. In this embodiment, it adopts the form of hydraulic cylinder drive. The cylinder body is installed on the second seat 12, and the cylinder rod is connected to the first seat 11. The cylinder rod and the rotating shaft are located on opposite sides of the first seat 11, so that the hydraulic cylinder can drive one side of the first seat 11 to rise and fall, so that the first seat 11 rotates around the rotating shaft.

[0034] In this embodiment, the agitator 31 has a first flow channel for introducing a medium. The first flow channel is disposed inside the agitator 31, and inlet and outlet are provided at both ends of the first flow channel, so that the first flow channel can be connected and cooperated with an external medium supply device through the inlet and outlet. During use, a medium of a certain temperature can be provided to the first flow channel through the medium supply device, so that the temperature near the agitator 31 is maintained within a predetermined range, thereby ensuring the mixing effect.

[0035] In this embodiment, the mixing device further includes a jacket 60, which is disposed at the bottom and / or side of the container 20. The jacket 60 has a second flow channel for introducing a medium. The second flow channel is configured similarly to the first flow channel, also located inside the jacket 60, and can also be connected to an external medium supply device. This allows a medium of a certain temperature to be introduced into the second flow channel during use, thereby maintaining the container 20 as a whole within a predetermined temperature range and achieving temperature control during mixing.

[0036] In this embodiment, the container 20 has a discharge pipe 21, which is connected to the interior of the container 20 and located on the lower side of the container 20. A valve or other control structure can be installed at the discharge port of the discharge pipe 21. During mixing, the valve at the discharge port is closed, keeping the material within the container 20 for mixing. Once mixing is complete, the discharge port opens. Because the discharge pipe 21 is located on the lower side of the container 20, the material can enter the discharge pipe 21 under gravity, facilitating discharge and reducing material residue.

[0037] In this embodiment, a feed inlet is provided at the top of the container 20. The feed inlet is located at a relatively high position on the top surface of the container 20 and above the central axis of the container 20, so that when the material enters the container 20 through the feed inlet, it can be mixed under the combined action of gravity and mechanical stirring.

[0038] The process of using the mixing device in this embodiment is as follows:

[0039] 1. The valve at the discharge port is closed;

[0040] 2. The material enters the container 20 through the feed inlet at the top of the container 20;

[0041] 3. When the dispersing component 41 and the stirring component 31 are started, the stirring component 31 rotates, which generates centrifugal force inside the container 20. The material rotates above the container 20. At this time, the dispersing component 41 and the stirring component 31 adopt opposite directions to improve the convection between the powders and achieve full mixing of different powders. At the same time, the jacket 60 is circulated with cooling medium water or heat transfer oil to cool and control the material temperature at 10-30℃.

[0042] 4. After a period of stirring to make the powder uniformly mixed, the dispersing component 41 increases its rotation speed and continuously shears and disperses the material through high-speed rotation (40-70m / s) linear velocity. At this time, the dispersing component 41 and the stirring component 31 rotate in the same direction, so that the binder will be fibrous under the action of high temperature and mechanical shear force. At the same time, hot water or heat transfer oil is introduced into the jacket 60, and the temperature of the powder is increased under the combined action of high-speed mechanical stirring and jacket 60 heating.

[0043] 5. After fiberization is completed, the dispersing component 41 stops rotating, the stirring component 31 rotates at low speed, and the jacket 60 and the stirring component 31 are circulated with cold water or cold heat transfer oil to cool the powder to 20-30℃.

[0044] 6. After the material cools down, the stirring component 31 and the dispersing component 41 rotate. The dispersing component 41 first rotates forward for a short time (less than 2 minutes), and then the dispersing component 41 rotates in reverse (less than 2 minutes) to break up and disperse the clumped material into powder.

[0045] 7. Once the final powder fiberization is complete, open the valve at the discharge port, and the agitator 31 will rotate at low speed to discharge the powder.

[0046] It should be noted that "multiple" in the above embodiments refers to at least two.

[0047] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0048] 1. This technology solves the problem of poor mixing effect during the fiberization and mixing process of electrode raw materials in existing technologies;

[0049] 2. Both the stirring and dispersing components can fully mix the materials and effectively promote the circulation of materials under the dual action of gravity and mechanical stirring. In particular, it has a better dispersion effect on materials with large differences in specific gravity, achieving higher efficiency and dispersion uniformity.

[0050] 3. Prevents damage to materials due to high-speed shearing, has high material mixing efficiency, and is highly adaptable to different materials and processes.
