[0009] In some embodiments, the ball mill jar further includes a connector that connects at least two of the electrode cores exposed at the ends of the insulating sleeve, the electrode cores being electrically connected to an external circuit via the connector.

[0010] In some embodiments, the flange includes a flange body and a flange end body. The flange body extends along the first direction, one end of the flange body is connected to the connecting cylinder, and the flange end body is connected to the other end of the flange body away from the connecting cylinder. The insulating sleeve includes an insulating sleeve body and an insulating sleeve end body. The insulating sleeve body is disposed within the flange body, one end of the insulating sleeve body extends into the connecting cylinder, and the insulating sleeve end body is connected to the other end of the insulating sleeve body and the insulating sleeve end body is connected to the flange end body.

[0011] In some embodiments, the ball mill jar further includes: a first sealing ring, which is sleeved on the electrode core and abuts against the insulating sleeve end body; and a sealing sleeve, which is sleeved on the electrode core and movably connected to the electrode core, the sealing sleeve being located on the side of the first sealing ring away from the insulating sleeve end body, and the sealing sleeve being adapted to press the first sealing ring toward the direction close to the insulating sleeve end body.

[0012] In some embodiments, the sealing sleeve has a groove on the side near the insulating sleeve end body; a portion of the first sealing ring is embedded in the groove, and another portion protrudes from the groove and abuts against the insulating sleeve end body.

[0016] Secondly, this application also discloses a plasma ball mill, which includes a plasma ball mill body and the grinding jar described in the first aspect, wherein the grinding jar is connected to the plasma ball mill body.

[0017] This application discloses a grinding jar and a plasma ball mill.

Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Figure 5 , showed Figure 4 A magnified view of a portion of the image.

[0038] This application discloses a ball mill jar, which includes a jar body 10. The jar body 10 has a first direction X and a second direction Y, where the second direction Y is the extending direction of the jar body 10. The jar body 10 includes a first cover 11 and a second cover 12 disposed opposite to each other along the second direction Y, and a connecting cylinder 13 connected between the first cover 11 and the second cover 12. The first direction X is the radial direction of the connecting cylinder 13. A flange 14 is disposed on the connecting cylinder 13, and the flange 14 extends along the first direction X. An insulating sleeve 20 is disposed at least partially inside the flange 14. An electrode core 30 is disposed inside the insulating sleeve 20, with one end of the electrode core 30 extending into the connecting cylinder 13 and the other end exposed outside the insulating sleeve 20. The end of the electrode core 30 exposed outside the insulating sleeve 20 is suitable for electrical connection to an external circuit.

[0039] This application discloses a ball mill jar for grinding and mixing various materials. For example, in the processing of lithium batteries, the ball mill jar can be used to uniformly mix raw materials such as metal powder, conductive agents, and binders, ensuring the consistency of the lithium battery's component distribution. Of course, the above are merely individual examples of specific applications of the ball mill jar, and the specific applications of the ball mill jar are not limited in this application. The following will use the ball mill jar for lithium battery processing as an example to illustrate the relevant aspects of the ball mill jar disclosed in this application.

[0040] The ball mill jar disclosed in this application includes a jar body 10, which forms a receiving cavity for holding materials to be mixed. The materials to be mixed include, but are not limited to, metal powder, conductive agents, and binders. The jar body 10 has an inlet and an outlet. The materials to be mixed can enter the jar body 10 through the inlet and flow out of the jar body 10 through the outlet after mixing is completed.

[0041] like Figure 2 As shown, the tank 10 has a first direction X and a second direction Y, where the second direction Y is the extending direction of the tank 10. The tank 10 includes a first cover 11 and a second cover 12 disposed opposite to each other along the second direction Y, and a connecting cylinder 13 connected between the first cover 11 and the second cover 12. The first cover 11, the second cover 12 and the connecting cylinder 13 enclose the tank 10, which has a receiving cavity.

[0042] It should be noted that the tank 10 in this embodiment can be a cylindrical structure, a cuboid structure, a pentagonal structure, or other irregular polygonal structures. In this embodiment, no excessive restrictions are placed on the specific structure of the tank 10. The following description will use a cylindrical tank 10 as an example.

[0043] like Figure 2As shown, the tank body 10 has intersecting first direction X and second direction Y. The first direction X is the radial direction of the connecting cylinder 13, that is, the direction in which the cross-section of the connecting cylinder 13 is located. The second direction Y is the extending direction of the tank body 10; alternatively, the second direction Y can be understood as the axial direction of the connecting cylinder 13.

[0044] like Figure 4 As shown in the embodiments of this application, the ball mill jar also includes an insulating sleeve 20 and an electrode core 30. A flange 14 is provided on the connecting cylinder 13, protruding from the outer wall of the connecting cylinder 13. The flange 14 extends along a first direction X, that is, it extends radially along the connecting cylinder 13 and is connected to the connecting cylinder 13. It can be understood that a through hole is provided inside the flange 14, which connects to the receiving cavity. A portion of the insulating sleeve 20 is disposed within the flange 14, and another portion is engaged with the end of the flange 14 away from the connecting cylinder 13. The electrode core 30 is disposed within the insulating sleeve 20 to isolate the jar body 10 and the electrode core 30 through the insulating sleeve 20, preventing the electrode core 30 from conducting with the jar body 10 and causing leakage in the ball mill jar.

[0045] The insulating sleeve 20 is insulating. For example, the insulating sleeve 20 is a ceramic insulating sleeve.

[0046] It should be noted that the electrode core 30 in this embodiment has a first end and a second end arranged opposite to each other. The electrode core 30 is disposed inside the insulating sleeve 20. The first end of the electrode core 30 extends into the connecting cylinder 13, and the second end of the electrode core 30 is exposed outside the insulating sleeve 20. The second end of the electrode core 30 exposed outside the insulating sleeve 20 is connected to an external circuit. The tank body 10 is grounded, and the electrode core 30 is connected to the external circuit. A voltage difference is formed between the tank body 10 and the electrode core 30, thereby creating a discharge effect, eliminating the static electricity accumulated in the tank body 10, and preventing electrostatic discharge from causing a combustion or explosion accident.

[0047] Furthermore, in this embodiment, the electrode core 30 extends along the first direction X, that is, the electrode core 30 extends radially along the connecting cylinder 13, resulting in a shorter length and better rigidity of the electrode core 30, thereby helping to improve the reliability of the ball mill jar. Moreover, the shorter length of the electrode core 30 means it occupies less space within the jar body 10, which also helps to improve the space utilization of the jar body 10.

[0048] In some embodiments, such as Figure 1 As shown, the flange 14 includes at least two flanges 14, which are spaced apart along the second direction Y; the insulating sleeve 20 and the electrode core 30 also include at least two, with each insulating sleeve 20 and each electrode core 30 corresponding to one flange 14.

[0049] like Figure 1As shown in this embodiment, at least two flanges 14 are provided on the connecting cylinder 13. These flanges 14 are spaced apart along the second direction Y, meaning they are axially spaced on the outer wall of the connecting cylinder 13, and both flanges 14 communicate with the receiving cavity. It can be understood that at least two flanges 14 protrude from the outer wall of the connecting cylinder 13, and each flange 14 has a through hole that communicates with the receiving cavity formed by the first cover 11, the second cover 12, and the connecting cylinder 13.

[0050] Each flange 14 is provided with an insulating sleeve 20, and each insulating sleeve 20 is provided with an electrode core 30. Each insulating sleeve 20 blocks the corresponding flange 14 and electrode core 30 to prevent the electrode core 30 from conducting with the corresponding flange 14, which would cause leakage in the ball mill jar.

[0051] In one preferred embodiment, three flanges 14 are provided, spaced apart along the second direction Y; three insulating sleeves 20 and three electrode cores 30 are also provided, with each insulating sleeve 20 and each electrode core 30 corresponding to one flange 14.

[0052] Of course, the above are merely individual examples of the specific quantities of flange 14, insulating sleeve 20, and electrode core 30, and are not intended to limit this application. In practical applications, technicians can set the quantities of flange 14, insulating sleeve 20, and electrode core 30 as needed. For example, the quantities of flange 14, insulating sleeve 20, and electrode core 30 can be 2, 3, 4, 5, 6, etc.

[0053] In this embodiment, the electrode cores 30 include multiple cores. The first ends of each core extend into the connecting cylinder 13, and the second ends of each core extend out of the insulating sleeve 20. The exposed second ends of each core are connected to an external circuit. In other words, the tank 10 is grounded, and the second ends of each core are electrically connected to an external circuit, creating a voltage difference between the tank 10 and the cores. This generates a discharge effect, eliminating static electricity accumulated in the tank 10 and preventing electrostatic discharge from causing a fire or explosion.

[0054] Furthermore, in this embodiment, the plurality of electrode cores 30 all extend along the first direction X, resulting in shorter lengths and better rigidity for each electrode core 30, thereby contributing to improved reliability of the ball mill jar. Moreover, the arrangement of multiple electrode cores 30 also helps to improve the discharge effect and enhance the efficiency of eliminating static electricity accumulated inside the jar, thereby further ensuring the reliability of the ball mill jar. In some embodiments, such as Figure 1 As shown, the ball mill jar also includes a connector 40, which connects at least two electrode cores 30 exposed at the ends of the insulating sleeve 20, and the connector 40 is adapted to be electrically connected to an external circuit.

[0055] like Figure 1 As shown in the embodiment of this application, the connector 40 is electrically connected to the ends of at least two electrode cores 30 exposed outside the insulating sleeve 20, so as to connect at least two electrode cores 30 in parallel. During the use of the ball mill jar, the jar body 10 can be grounded, and the connector 40 can be electrically connected to an external circuit, so that a voltage difference is formed between the jar body 10 and the electrode cores 30, thereby creating a discharge effect, eliminating the static electricity accumulated in the jar body 10, and preventing electrostatic discharge from causing a combustion or explosion accident.

[0056] It should be noted that the connector 40 is a conductive component, which can conduct electricity between the electrode core 30 and the external circuit. By connecting at least two electrode cores 30 in parallel through the connector 40, a higher voltage difference can be formed between the tank 10 and the electrode cores 30, thereby further improving the discharge effect and enhancing the discharge effect of static electricity accumulated in the tank 10.

[0057] In some embodiments, such as Figure 4 As shown, flange 14 includes flange body 141 and flange end body 142. Flange body 141 extends along a first direction X. One end of flange body 141 is connected to connecting cylinder 13, and flange end body 142 is connected to the other end of flange body 141 away from connecting cylinder 13. Insulating sleeve 20 includes insulating sleeve body 21 and insulating sleeve end body 22. Insulating sleeve body 21 is disposed inside flange body 141. One end of insulating sleeve body 21 extends into connecting cylinder 13. Insulating sleeve end body 22 is connected to the other end of insulating sleeve body 21 and flange end body 142.

[0058] like Figure 4 As shown, flange 14 protrudes from connecting cylinder 13, and flange 14 includes flange body 141 and flange end body 142. One end of flange body 141 is fixedly connected to the outer wall of connecting cylinder 13, flange body 141 extends along the first direction X, and flange end body 142 is fixedly connected to the end of flange body 141 away from connecting cylinder 13.

[0059] It should be noted that, in this embodiment, the flange body 141 can be integrally formed with the flange end body 142, or the flange body 141 and the flange end body 142 can be separately formed. For example, the flange end body 142 is welded to the end of the flange body 141 away from the connecting cylinder 13.

[0060] like Figure 4As shown, the insulating sleeve 20 includes an insulating sleeve body 21 and an insulating sleeve end body 22. The insulating sleeve body 21 extends along a first direction X, with one end of the insulating sleeve body 21 extending into the connecting cylinder 13. The insulating sleeve end body 22 is fixedly connected to the other end of the insulating sleeve body 21. The insulating sleeve end body 22 abuts against the flange end body 142, and the insulating sleeve end body 22 is fixedly connected to the flange end body 142 to limit and fix the insulating sleeve end body 22. For example, the insulating sleeve end body 22 is fixedly connected to the flange end body 142 by bolts to limit and fix the insulating sleeve 20, preventing the insulating sleeve 20 from moving within the flange 14 and affecting the reliability of the ball mill jar.

[0061] It should be noted that, in this embodiment of the application, the insulating sleeve body 21 can be integrally formed with the insulating sleeve end body 22. For example, the insulating sleeve body 21 and the insulating sleeve end body 22 are integrally injection molded. Alternatively, the insulating sleeve body 21 and the insulating sleeve end body 22 can be separately formed.

[0062] In some embodiments, such as Figure 4 As shown, the ball mill jar also includes a first sealing ring 50, which is sleeved on the electrode core 30 and abuts against the insulating sleeve end body 22; and a sealing sleeve 60, which is sleeved on the electrode core 30 and movably connected to the electrode core 30. The sealing sleeve 60 is located on the side of the first sealing ring 50 away from the insulating sleeve end body 22, and the sealing sleeve 60 is adapted to press the first sealing ring 50 toward the direction closer to the insulating sleeve end body 22.

[0063] like Figure 4 As shown, in this embodiment, the first sealing ring 50 and the sealing sleeve 60 are sequentially fitted onto the electrode core 30. The first sealing ring 50 abuts against the insulating sleeve end body 22, and the sealing sleeve 60 is located on the side of the first sealing ring 50 away from the insulating sleeve end body 22, and the sealing sleeve 60 is movably connected to the electrode core 30. The sealing sleeve 60 presses the first sealing ring 50 towards the insulating sleeve end body 22, so that the first sealing ring 50 can seal the gap between the electrode core 30 and the insulating sleeve body 21, ensuring the sealing effect of the ball mill jar.

[0064] It should be noted that, along the first direction X, the sealing sleeve 60 is movable relative to the electrode core 30, so that the sealing sleeve 60 can press the first sealing ring 50 toward the insulating sleeve end body 22. For example, the sealing sleeve 60 and the electrode core 30 are connected by threads; rotating the sealing sleeve 60 moves it toward the insulating sleeve end body 22, thus pressing the first sealing ring 50 toward the insulating sleeve end body 22.

[0065] In some embodiments, such as Figure 4As shown, a groove is provided on the side of the sealing sleeve 60 near the insulating sleeve end body 22; a part of the first sealing ring 50 is embedded in the groove, and the other part protrudes out of the groove and abuts against the insulating sleeve end body 22.

[0066] like Figure 4 As shown, a groove is provided on the side of the sealing sleeve 60 near the insulating sleeve end body 22. A portion of the first sealing ring 50 is embedded in the groove to fix the first sealing ring 50 and prevent it from shifting, which would affect the sealing effect of the ball mill jar. Another portion of the first sealing ring 50 protrudes from the groove and abuts against the insulating sleeve end body 22. The portion of the first sealing ring 50 protruding from the groove seals the gap between the electrode core 30 and the insulating sleeve body 21, ensuring the sealing effect of the ball mill jar.

[0067] In some embodiments, along the first direction X, the thickness of the first sealing ring 50 is L1, and the depth of the groove is L2, satisfying that L1-L2≥1mm.

[0068] like Figure 4 As shown, along the first direction X, the thickness of the first sealing ring 50 is set to L1, and the depth of the groove is set to L2, wherein L1 is greater than L2, and the difference between L1 and L2 is greater than or equal to 1mm, so that the part of the first sealing ring 50 protruding from the groove is high enough to seal the gap between the electrode core 30 and the insulating sleeve body 21, and ensure the sealing effect of the ball mill jar.

[0069] For example, along the first direction X, the difference between the thickness L1 of the first sealing ring 50 and the depth L2 of the groove can be 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.3mm, 2.5mm, etc.

[0070] In a preferred embodiment, along the first direction X, the difference between the thickness L1 of the first sealing ring 50 and the depth L2 of the groove can be set to be less than or equal to 2mm, so as to avoid the portion of the first sealing ring 50 protruding from the groove being too large, resulting in poor sealing effect.

[0071] For example, along the first direction X, the difference between the thickness L1 of the first sealing ring 50 and the depth L2 of the groove can be 1 mm, 1.3 mm, 1.6 mm, 1.9 mm, 2 mm, etc.

[0072] In some embodiments, the sealing sleeve 60 is threadedly connected to the electrode core 30.

[0073] In this embodiment, a first thread can be provided on the outer wall of the electrode core 30, and a second thread can be provided on the outer wall of the sealing sleeve 60. The sealing sleeve 60 is fitted onto the electrode core 30, and the second thread can rotate relative to the first thread, thereby allowing the sealing sleeve 60 to rotate relative to the electrode core 30 in the first direction X. The sealing sleeve 60 can press the first sealing ring 50 towards the direction close to the insulating sleeve end body 22, and the first sealing ring 50 can seal the gap between the electrode core 30 and the insulating sleeve body 21, ensuring the sealing effect of the ball mill jar.

[0074] In some embodiments, such as Figure 4 As shown, the ball mill jar also includes a second sealing ring 70, which is disposed between the flange end body 142 and the insulating sleeve end body 22.

[0075] like Figure 4 As shown in the embodiment of this application, a second sealing ring 70 is provided between the flange end body 142 and the insulating sleeve end body 22. The second sealing ring 70 seals the gap between the flange end body 142 and the insulating sleeve end body 22, thereby ensuring the sealing effect of the ball mill jar.

[0076] In some embodiments, the flange body 141 is clearance-fitted with the insulating sleeve body 21; and / or, the electrode core 30 is clearance-fitted with the insulating sleeve body 21.

[0077] In this embodiment, the flange body 141 and the insulating sleeve body 21 are clearance-fitted. That is, the flange body 21 has a first through hole, the diameter of which is larger than the diameter of the insulating sleeve body 21, to ensure a clearance fit between the flange body 21 and the insulating sleeve body 21. This prevents the insulating sleeve body 21 from expanding and contracting due to temperature changes during the use of the ball mill jar, which could affect the fit between the insulating sleeve body 21 and the flange body 21.

[0078] For example, a first through hole is provided in the flange body 21, and the diameter of the first through hole is 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc. larger than the diameter of the insulating sleeve body 21.

[0079] In this embodiment, the electrode core 30 and the insulating sleeve body 21 are in a clearance fit. That is, a second through hole is provided inside the insulating sleeve body 21, and the diameter of the second through hole is larger than the diameter of the electrode core 30, so that the electrode core 30 and the insulating sleeve body 21 are in a clearance fit. This is to avoid the electrode core 30 from expanding and contracting due to temperature changes during the use of the ball mill jar, which would affect the fit between the electrode core 30 and the insulating sleeve body 21.

[0080] For example, a second through hole is provided in the insulating sleeve body 21, and the diameter of the second through hole is 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, etc., larger than the diameter of the electrode core 30.

[0081] This application also discloses a plasma ball mill, which includes a plasma ball mill body and the grinding jar described in the above embodiments, wherein the grinding jar is connected to the plasma ball mill.

Therefore, the appended claims are intended to be interpreted as including the alternative embodiments as well as all changes and modifications falling within the scope of the present invention.
