Description

Technical Field

[0001] This utility model relates to the field of mixing technology, specifically to a mixing machine for producing battery negative electrode materials. Background Technology

[0002] In existing mixer technology, the conventional practice for mixing graphite, conductive agents, and other additives is to pour them all into the mixing tank of the mixer at a predetermined ratio and allow them to accumulate naturally. The mixing mechanism is then activated to blend these accumulated materials. However, this method has several significant drawbacks.

[0003] On the one hand, because the materials are initially densely packed in the mixing tank, achieving an ideal, uniform mixture usually requires a long mixing time. This not only affects production efficiency but also increases energy consumption.

[0004] On the other hand, during the mixing process, some of the mixture tends to adhere to the inner wall of the mixing tank. This not only reduces the uniformity of the mixture but may also cause wear and even contamination to the inner wall of the mixing tank. The adhered mixture may also gradually accumulate, forming a difficult-to-remove deposit, further affecting the performance of the mixer and the quality of the mixture.

[0005] Furthermore, during the discharge process after mixing, material tends to accumulate on the inner wall of the mixing tank and at the sealing gate of the discharge port. This accumulated material is not only difficult to clean completely, but it can also negatively impact subsequent mixing processes and even threaten the normal operation of the mixer.

[0006] Therefore, it can be seen that existing mixer technology has obvious problems in the mixing process, such as long mixing time, easy adhesion of mixture to the inner wall of the mixing tank, and easy accumulation of material during discharge.

[0007] Based on this, this utility model designs a mixer for producing battery negative electrode materials to solve the above problems. Utility Model Content

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0041] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0042] In some embodiments, please refer to the accompanying drawings. Figures 1-5 A mixer for producing battery negative electrode materials includes: a mixing tank 1 for mixing and placing materials; a conical part 2 disposed at the bottom of the mixing tank 1 and communicating with the interior of the mixing tank 1 for the flow of the mixture during mixing or discharging, ensuring smooth flow of the mixture during mixing and discharging, reducing material accumulation, and facilitating cleaning and maintenance; a stirring rod 3 rotatably disposed inside the mixing tank 1; a hinge assembly 4 mounted on the stirring rod 3; and a dividing paddle assembly 5 mounted on the hinge assembly 4 for mixing the mixture.

[0043] The angle of the segmented propeller assembly 5 is adjusted by the position adjustment of the hinge assembly 4. The segmented propeller assembly 5 consists of a segmented propeller 51, a folding plate 52 and a flow hole 53. The cross-section of the segmented propeller 51 is conical. The folding plate 52 is symmetrically installed on both sides of the segmented propeller 51.

[0044] The baffle plate 52 has a bent structure along the side of the segmented impeller 51, and the flow holes 53 are formed on the baffle plate 52. The baffle plate 52 and the flow holes 53 can change the flow path of the fluid during the stirring process, thereby reducing energy consumption. These designs help to reduce turbulence and vortices of the fluid around the impeller, reduce resistance during the stirring process, and thus save energy.

[0045] By designing the cross-section of the dividing paddle 51 to be conical, strong eddies and shear forces are generated during material mixing. This hydrodynamic characteristic allows for more thorough mixing of materials in a short time, improving mixing efficiency. Furthermore, it helps to form a more complex flow field during mixing, promoting interaction and collision between materials, further enhancing mixing uniformity. The bent design of the baffle 52 increases the effective mixing area of ​​the dividing paddle 51 during mixing, thereby enhancing the mixing effect. The baffle 52 generates additional hydrodynamic force when rotating, helping to distribute materials more evenly in the mixing container. The flow holes 53 allow fluid to pass through, further promoting material mixing. When the dividing paddle 51 and baffle 52 rotate, fluid flows out through the holes, forming jets and eddies. These flow patterns help break down the interfaces between materials, achieving more thorough mixing.

[0046] In this embodiment, the hinge assembly 4 consists of a mounting base 41, a first locking seat 42, a sliding member 43, a rotating crank 44, a second locking seat 45, a fixed crank 46, and a guide rod 47. The first locking seat 42 and the second locking seat 45 are mounted on the mounting base 41 in a symmetrical staggered structure to achieve balance and stability on both sides. One end of the sliding member 43 is fixed to the first locking seat 42. The sliding member 43 is a sliding sleeve and sliding rod structure. One end of the sliding rod structure of the sliding member 43 slides along the inside of the sliding sleeve, and the other end of the sliding rod structure can slide inside the sliding sleeve to achieve displacement in a specific direction. This sliding sleeve and slide rod structure provides the necessary motion basis for subsequent angle adjustment. One end of the fixed crank 46 is fixed to the second locking seat 45, and the rotating crank 44 passes through the second locking seat 45 and is hinged to it. The rotating crank 44 is hinged to the second locking seat 45 by screws. The second locking seat 45 has a sliding groove, and the rotating crank 44 moves along the groove. This design allows the rotating crank 44 to rotate along a predetermined trajectory, ensuring the stability and accuracy of the motion. The other end of the sliding member 43... One end is fixedly connected to one side of the rotating crank 44. When the rotating crank 44 rotates, it can drive the sliding rod structure of the sliding member 43 to slide inside the sliding sleeve, thereby guiding and supporting the rotation of the rotating crank 44. One end of the guide rod 47 is hinged to one side of the second locking seat 45. When the rotating crank 44 rotates, the guide rod 47 can move hingedly with the rotation of the second locking seat 45, which increases the stability and reliability of the entire structure. A connecting seat is installed on one side of the rotating crank 44 and one end of the guide rod 47. One side of the connecting seat is fixedly installed on one side of the dividing paddle 51.

[0047] During the initial mixing of the materials, the operator uses a wrench to turn the screw between the rotating crank 44 and the second locking seat 45 to one side, releasing the fixing force between the rotating crank 44 and the second locking seat 45. Turning the rotating crank 44 to one side causes it to move in an arc along the sliding groove of the second locking seat 45. At this time, one side of the rotating crank 44 drives the sliding rod structure of the first locking seat 42 to slide along the inside of the sliding sleeve structure of the sliding member 43, guiding the rotation of the rotating crank 44. At this time, one side of the rotating crank 44 drives the connecting seat to move in the same direction, and drives the dividing paddle assembly 5 to change its angle, ensuring that the dividing paddle assembly 5 can be stably fixed at the required angle. When the dividing paddle assembly 5 is adjusted by the connecting seat, one end of the guide rod 47 is hinged along one end of the second locking seat 45, further improving the stability of the angle adjustment of the dividing paddle assembly 5. The angle of the dividing paddle assembly 5 directly affects the flow mode and mixing effect of the material in the mixing tank 1. By adjusting the angle of the dividing paddle assembly 5, the flow trajectory of the material can be optimized, making it more evenly distributed in the mixing chamber, thereby improving the mixing uniformity. Depending on the characteristics of the material and the mixing requirements, adjusting the angle of the dividing paddle 51 can enhance or weaken the shear force or impact force it generates. This is especially important for certain materials that require specific mixing effects, such as viscous materials that require strong shearing or granular materials that require impact, effectively preventing the accumulation of material due to material buildup.

[0048] In this embodiment, a drive motor 6 is also included. The output end of the drive motor 6 and one end of the stirring rod 3 are fixedly installed. A support sleeve is installed on the outside of the stirring rod 3. One side of the mounting base 41 is installed on the support sleeve to provide installation space for the hinge assembly 4.

[0049] In this embodiment, a vibrator 7 is installed at the bottom of the conical part 2, and a discharge port is opened at the bottom of the conical part 2 to discharge the mixed material.

[0050] In this embodiment, a spiral stirring paddle is installed at the bottom of the stirring rod 3 to stir the material at the bottom of the stirring tank 1, preventing sedimentation at the bottom of the stirring tank 1 and thus preventing material accumulation.

[0051] In this embodiment, a support cavity is installed at the bottom of the conical part 2, and the vibrator 7 and the conical part 2 are installed in the support cavity.

[0052] In this embodiment, multiple sets of reinforcing ribs are fixed to the outside of the support cavity to improve the load-bearing capacity of the mixing tank, enabling it to withstand greater mixing force and pressure. The reinforcing ribs help enhance the stability of the mixing tank and prevent deformation or cracking during mixing. The reinforcing ribs can guide the distribution of stress in the mixing tank, making it more uniform, thereby avoiding damage caused by excessive local stress. Since the overall strength and rigidity of the mixing tank are enhanced, its service life can be extended, reducing maintenance and replacement costs.

[0053] In this embodiment, the mixing tank 1, hinge assembly 4, dividing paddle assembly 5 and spiral mixing paddle are provided with an anti-stick coating. The anti-stick coating includes, but is not limited to, Teflon or other polymer materials, and its purpose is to reduce the adhesion of the mixture during the mixing process.

[0054] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
