Description

Technical Field

[0001] This utility model relates to the field of sodium-ion battery technology, specifically to a ball milling device for synthesizing sodium-ion battery materials. Background Technology

[0002] Lithium-ion batteries are currently widely used in portable electronic products, communication equipment and electric vehicles, but they are expensive and have poor safety. Sodium-ion batteries, on the other hand, are expected to replace lithium-ion batteries and become energy storage systems used on a large scale due to their excellent electrochemical performance and low cost.

[0003] The negative electrode material of sodium-ion battery needs to be ground by ball milling device during preparation. Existing grinding devices usually use grinding balls to grind the material and are equipped with a filter screen for filtration. However, the material is prone to leakage from the filter screen during the grinding process, and the grinding balls can easily block the filter screen during discharge, causing discharge difficulties.

[0004] For example, a ball milling device for lithium battery cathode materials (Announcement No.: CN215312823U) includes a grinding cylinder, a feed inlet, a driven wheel, a driving wheel, a belt, a motor, sieve holes, grinding balls, a collection box, and a screen. The motor drives the driving wheel to rotate, which in turn drives the driven wheel via the belt, causing the grinding cylinder to rotate. The grinding balls inside rise due to the centrifugal force generated by the rotation of the grinding cylinder. When the grinding balls rise to a certain height, the gravitational force they experience exceeds the centrifugal force, thus causing the grinding balls to fall back to their starting position under the influence of gravity. The grinding balls rapidly descend and impact and rub against the material to achieve the grinding effect. However, in actual use, as the grinding cylinder rotates, the position of the sieve holes also moves in a circular motion. Under the action of centrifugal force, the material inside the grinding cylinder will be thrown out through the sieve holes. Moreover, the grinding balls will also block the sieve holes during discharge, affecting the discharge. That is, there are the problems mentioned above, such as the material easily leaking from the filter screen during the grinding process and the grinding balls easily blocking the filter screen during discharge, causing difficulties in discharge. Therefore, we need to propose a ball mill device for the synthesis of sodium-ion battery materials. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution:

[0031] A ball milling device for synthesizing sodium-ion battery materials includes: a base 1, on which a U-shaped frame 2 and a support frame 3 are fixedly installed on both sides of its top; a bottom plate 4, rotatably connected to the inner walls of the U-shaped frame 2, and its bottom abutting against the top of the support frame 3; two sets of auxiliary frames 5, on which grinding barrels 6 are rotatably mounted, and a cover plate 7 is detachably installed on the outer wall of the grinding barrels 6, and one end of the grinding barrels 6 is also fixedly connected to a discharge pipe; an auxiliary feeding mechanism 8, located on the top of the base 1, used to tilt the bottom plate 4 to facilitate the discharge of materials from the grinding barrels 6; a rotating mechanism 9, located on the bottom plate 4 and the grinding barrels 6, used to rotate the grinding barrels 6; and a grinding mechanism 10, located on the grinding barrels 6, used to grind the materials.

[0032] In this embodiment, by providing a detachable cover plate 7, when grinding the material, the cover plate 7 is fixed, and then the grinding barrel 6 is driven to roll on the two sets of auxiliary frames 5 by the rotating mechanism 9, which allows the material inside the grinding barrel 6 to roll, and then the grinding mechanism 10 grinds the material. The rotation of the grinding barrel 6 can prevent the material from accumulating on the bottom side of the inner wall of the grinding barrel 6, which is conducive to the uniform grinding of the material. After the material is ground, the bottom plate 4 is tilted by the auxiliary feeding mechanism 8. Under the action of gravity, the material will move towards the discharge pipe, which is convenient for the ground material to be discharged. It has high practicality.

[0033] It is worth noting that the discharge pipe is equipped with a valve, and when installing the base plate 4, U-shaped frame 2 and support frame 3, attention should be paid to the horizontal state of the base plate 4. It should be ensured that the bottom of the base plate 4 is in a horizontal state when it is in contact with the support frame 3, and tilting should be avoided.

[0034] A feed inlet 14 is provided on the outer wall of the grinding barrel 6. A pad frame 15 is fixedly installed inside the feed inlet 14, and the cover plate 7 is fixedly installed on the pad frame 15 by screws.

[0035] In this embodiment, removing the cover plate 7 allows the material to enter the interior of the grinding barrel 6 through the feed port 14. Then, the cover plate 7 is installed to prevent the material from being thrown out when the grinding barrel 6 is rotated. Furthermore, by providing the gasket frame 15, the sealing effect between the cover plate 7 and the grinding barrel 6 can be guaranteed.

[0036] The auxiliary feeding mechanism 8 includes a threaded rod 81, a first drive motor 82, two sets of limit rods 83, a moving plate 84, and two sets of support rods 85. One end of the threaded rod 81 is rotatably connected to the U-shaped frame 2, and the other end of the threaded rod 81 is fixedly connected to the first drive motor 82. The moving plate 84 is threadedly connected to the outer wall of the threaded rod 81. One end of each of the two sets of support rods 85 is hinged to the top of the moving plate 84, and the other end of each of the two sets of support rods 85 is hinged to the bottom of the base plate 4.

[0037] In this embodiment, the output end of the first drive motor 82 drives the threaded rod 81 connected to it to rotate, causing the moving plate 84 to move. Since the two ends of the support rod 85 are hinged to the moving plate 84 and the base plate 4 respectively, the tilt angle of the support rod 85 will change. The base plate 4 is rotatably connected to both sides of the inner wall of the U-shaped frame 2. This allows the support rod 85 to lift the base plate 4 when it tilts, changing the tilt angle of the base plate 4, and thus changing the tilt angle of the grinding barrel 6. Under the action of gravity, the material will move towards the discharge pipe, making it easier to discharge the ground material.

[0038] One end of each of the two sets of limiting rods 83 is fixedly connected to the U-shaped frame 2, and the other end of each of the two sets of limiting rods 83 is fixedly connected to the support frame 3. The movable plate 84 is slidably installed on the outer wall of the two sets of limiting rods 83.

[0039] In this embodiment, the movable plate 84 is limited by two sets of limiting rods 83, so that the threaded rod 81 can move the movable plate 84 when it rotates.

[0040] The rotating mechanism 9 includes a second drive motor 91, a first connecting rod 92, a driving pulley 93, a driven pulley 94, a belt 95, and a second connecting rod 96. The second drive motor 91 is fixedly installed on the top of the base plate 4. The output end of the second drive motor 91 is fixedly connected to the first connecting rod 92. The driving pulley 93 is fixedly sleeved on the outer wall of the first connecting rod 92. One end of the second connecting rod 96 is fixedly connected to the grinding barrel 6. The driven pulley 94 is fixedly sleeved on the outer wall of the second connecting rod 96. The driven pulley 94 and the driving pulley 93 are connected by a belt 95.

[0041] In this embodiment, the output end of the second drive motor 91 drives the first connecting rod 92 connected to it to rotate. The first connecting rod 92 drives the active pulley 93 to rotate. The active pulley 93 drives the driven pulley 94 to rotate through the belt 95, causing the second connecting rod 96 to rotate. The second connecting rod 96 drives the grinding barrel 6 to roll, thereby enabling the material inside the grinding barrel 6 to tumble and avoid material accumulation.

[0042] The auxiliary frame 5 includes an auxiliary seat 51 and several sets of rotating wheels 52. A limiting slide 11 is fixedly sleeved on the outer wall of the grinding barrel 6, and the outer walls of the several sets of rotating wheels 52 are all in contact with the inner wall of the limiting slide 11.

[0043] In this embodiment, the grinding barrel 6 rotates on the auxiliary frame 5 under the action of the rotating mechanism 9. The auxiliary seat 51 is used for support, and the rotating wheel 52 rotates to ensure the stability and smoothness of the grinding barrel 6 when it rolls.

[0044] The grinding mechanism 10 includes a rotating rod 101, a third drive motor 102, and several sets of grinding rods 103. The rotating rod 101 is rotatably installed inside the grinding barrel 6. One end of the rotating rod 101 passes through the grinding barrel 6 and is fixedly connected to the third drive motor 102. Several sets of grinding rods 103 are fixedly installed at equal intervals on the outer wall of the rotating rod 101.

[0045] In this embodiment, the output end of the third drive motor 102 drives the rotating rod 101 connected to it to rotate, and the rotating rod 101 drives the grinding rod 103 connected to it to rotate, so that the grinding rod 103 grinds the material inside the grinding barrel 6. Specifically, the rotation direction of the grinding rod 103 should be opposite to the rotation direction of the grinding barrel 6 to increase the friction between the material and the grinding rod 103 and improve the grinding effect.

[0046] Two sets of vertical plates 12 are symmetrically fixedly installed on the top of the base plate 4. A mounting plate 13 is fixedly connected to one side of the two sets of vertical plates 12. The third drive motor 102 is fixedly installed on one side of the mounting plate 13.

[0047] In this embodiment, two sets of vertical plates 12 support the mounting plate 13, which in turn supports and fixes the third drive motor 102, preventing the third drive motor 102 from rotating when the grinding barrel 6 rotates.

[0048] In this application, the first drive motor 82 can be a 57BYG250H stepper motor, the second drive motor 91 can be a Y2-90L-4 three-phase asynchronous motor, and the third drive motor 102 can be a YE2-100L1-4 three-phase asynchronous motor. The first drive motor 82, the second drive motor 91, and the third drive motor 102 are all finished products in the prior art. Their specific working principles, installation methods, and wiring connections can be learned from the purchased manuals, and will not be described in detail here.

[0049] Working principle: When this utility model is in use, a detachable cover plate 7 is provided. When grinding materials, the cover plate 7 is fixed, and then the rotating mechanism 9 drives the grinding barrel 6 to roll on two sets of auxiliary frames 5. This allows the material inside the grinding barrel 6 to roll, and then the grinding mechanism 10 grinds the material. The rotation of the grinding barrel 6 can prevent the material from accumulating on the bottom of the inner wall of the grinding barrel 6, which facilitates the uniform grinding of the material. After the material is ground, the auxiliary feeding mechanism 8 tilts the bottom plate 4. Under the action of gravity, the material will move towards the discharge pipe, which facilitates the discharge of the ground material. It has high practicality.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
