[0044] The plasma ball milling apparatus includes a grinding jar and an electrode rod inserted into the grinding jar, through which plasma is introduced into the grinding jar. In related technologies, the electrode rod typically extends into the interior of the grinding jar from the center of its side along its axial direction. Furthermore, to ensure uniform plasma distribution within the grinding jar, the portion of the electrode rod extending into the grinding jar is relatively long.
[0045] However, since the electrode rod is usually a slender structure, when the length of the electrode rod extending into the ball mill jar is large, the electrode rod may deform. In order to avoid the deformation of the electrode rod, methods such as increasing the size of the electrode rod will result in the electrode rod occupying a large volume in the ball mill jar, which will reduce the working efficiency of the plasma ball milling device.
[0046] This application provides a ball mill jar assembly 100, specifically, the ball mill jar assembly 100 is applied to a plasma ball milling apparatus. The ball mill jar assembly 100 of this application will be described in detail below with reference to the accompanying drawings.
[0047] This application discloses a ball mill jar assembly 100, referring to... Figures 1-4The ball milling jar assembly 100 includes: a ball milling jar 1 having intersecting first direction X and second direction Y, the first direction X being the axial direction of the ball milling jar 1, the ball milling jar 1 including a first end 11 and a second end 12 disposed opposite to each other along the second direction Y, the second end 12 being used to connect to a plasma ball milling device, the length of the ball milling jar 1 along the first direction X being a, the height of the ball milling jar 1 along the second direction Y being b, wherein a > b; and a plurality of electrode rods 2, the plurality of electrode rods 2 being disposed at intervals along the first direction X at the first end 11, and partially extending into the ball milling jar 1 from the first end 11.
[0048] Specifically, such as Figure 1 As shown, the first direction X is the X-axis direction as indicated by the arrow, and the first direction X is the axial direction of the ball mill jar 1. The second direction Y is the Y-axis direction as indicated by the arrow. The second direction Y intersects with the first direction X. Preferably, the second direction Y is perpendicular to the first direction X, and the second direction Y is the radial direction of the ball mill jar 1.
[0049] The grinding jar 1 is used to contain the material to be ground. Appropriate grinding media can be added to the grinding jar 1. The grinding media can include, but are not limited to, steel balls and ceramic balls. The grinding purpose is achieved by causing the material to be ground to collide and rub against the grinding media.
[0050] The ball mill jar 1 includes a first end 11 and a second end 12 disposed opposite to each other along the second direction Y. The second end 12 is the bottom end of the ball mill jar 1 along the second direction Y and is used for connecting the vibrating element to fix the ball mill jar 1. The first end 11 is the top end of the ball mill jar 1 along the second direction Y.
[0051] Multiple electrode rods 2 are spaced apart at the first end 11 of the ball mill jar 1 along the first direction X. Multiple electrode rods 2 extend into the ball mill jar 1 from the first end 11 along the second direction Y. The electrode rods 2 and the jar body of the ball mill jar 1 are respectively connected to the two poles of an external AC power supply, thereby realizing corona discharge or glow discharge and introducing plasma into the interior of the ball mill jar 1.
[0052] The length 'a' of the grinding jar 1 along the first direction X refers to the straight-line distance 'a' between the two ends of the grinding jar 1 along the first direction X, and the height 'b' of the grinding jar 1 along the second direction Y refers to the straight-line distance 'b' between the two ends of the grinding jar 1 along the second direction Y, where a > b. The value of 'a' can be in the range of 600mm ≤ a ≤ 1000mm, and the value of 'b' can be in the range of 200mm ≤ b ≤ 400mm. The distance between two adjacent electrode rods 2 is L, and the setting range of L can be L < 0.3a.
[0053] When multiple electrode rods 2 extend into the ball mill jar 1 from the first end 11, since a is greater than b, the size of the multiple electrode rods 2 extending into the ball mill jar 1 is small, the length of each electrode rod 2 can be shortened, and the arrangement of multiple electrode rods 2 can realize multi-point discharge, so that the plasma is evenly distributed in the ball mill jar 1.
[0054] It should be noted that the number of electrode rods 2 can be 2, 3, 4, etc., and can be specifically set according to the size and distance of the ball mill jar 1 and cost factors. This application embodiment does not make specific limitations in this regard.
[0055] For example, in this embodiment, the number of electrode rods 2 can be three. Specifically, since each electrode rod 2 has a certain discharge distance limitation, within the length a of the ball mill jar 1 in the first direction, the ball mill jar 1 can be equipped with more than three electrode rods 2. The more electrode rods 2 there are, the more uniformly the material in the ball mill jar 1 can be affected by the discharge of the electrode rods 2, resulting in a more uniform and effective discharge effect. However, while increasing the number of electrode rods 2 can further improve the discharge effect, it also leads to an increase in equipment manufacturing costs. After multiple experiments, it was determined that using three electrode rods 2, and since the distance L between two adjacent electrode rods 2 is less than 0.3a, when a = 630mm and b = 200mm, the distance L between two adjacent electrode rods 2 in the three electrode rods 2 is 155mm. This ensures the discharge effect while keeping the cost within a reasonable range.
[0056] In this embodiment, by extending multiple electrode rods 2 into the ball mill jar 1 from the first end 11 arranged along the second direction Y, compared with the prior art installation method of inserting the electrode rods 2 from the side end of the ball mill jar 1 along the first direction X, the length of each electrode rod can be shortened, which can reduce the size of the electrode rod 2 extending into the ball mill jar 1, thereby reducing the occurrence of problems such as electrode rod 2 deformation or occupying a large volume in the ball mill jar 1, and improving the working efficiency of the plasma ball milling device.
[0057] In some embodiments, the ball mill jar 1 is provided with a receiving cavity 10, and a plurality of mounting joints 13 are provided at intervals along a first direction X at the first end 11. The mounting joints 13 are in communication with the receiving cavity 10. The electrode rod 2 is fixedly connected to the mounting joint 13, and the electrode rod 2 extends into the ball mill jar 1 from the mounting joint 13.
[0058] Specifically, such as Figure 2 As shown, the ball mill jar 1 is provided with a receiving cavity 10. Multiple mounting joints 13 are provided at intervals at the first end 11 of the ball mill jar 1. The mounting joints 13 can be flange joints. The mounting joints 13 are provided with mounting through holes 130 that communicate with the receiving cavity 10. The electrode rod 2 can be fixedly connected to the mounting joint 13 by fasteners, and the electrode rod 2 extends into the receiving cavity 10 through the mounting through holes 130.
[0059] In practical applications, by setting multiple mounting joints 13 at the first end 11 of the ball mill jar 1, and the mounting joints 13 are connected to the receiving cavity 10 of the ball mill jar 1, multiple electrode rods 2 can be extended into the receiving cavity 10 from the first end 11 through the mounting joints 13. This allows the length of each electrode rod 2 to be shortened, reducing the size of the electrode rod 2 extending into the ball mill jar 1. This reduces the occurrence of problems such as electrode rod 2 deformation or occupying a large volume in the ball mill jar 1, thereby improving the working efficiency of the plasma ball milling device.
[0060] In some embodiments, the electrode rod 2 includes an electrode core 21 and an insulating member 22; the insulating member 22 is fixedly connected to the mounting joint 13, and the insulating member 22 is at least partially located within the mounting joint 13; the insulating member 22 is provided with a through hole 221 penetrating the insulating member 22, the electrode core 21 abuts against the insulating member 22, and partially extends through the through hole 221 into the receiving cavity 10.
[0061] Specifically, such as Figure 2 As shown, the insulating component 22 is a ceramic insulating component 22. The insulating component 22 can be fixedly connected to the mounting joint 13 by fasteners, and the insulating component 22 is disposed in the mounting through hole 130 of the mounting joint 13.
[0062] An insulating member 22 is provided with a through hole 221 extending through the insulating member 22 along the second direction Y. One end face of the electrode core 21 abuts against the top of the insulating member 22 along the second direction Y. There is a certain gap between the outer wall of the electrode core 21 and the hole wall of the through hole 221, so that the electrode core 21 extends into the interior of the receiving cavity 10 through the through hole 221. The electrode core 21 and the body of the ball mill jar 1 are respectively connected to the two poles of the plasma power supply, thereby realizing corona discharge or glow discharge and introducing plasma into the interior of the ball mill jar 1.
[0063] In this embodiment, the insulating component 22 separates the electrode core 21 from the ball mill jar 1, preventing direct contact between the two and thus avoiding short circuits, thereby achieving stable corona discharge or glow discharge. Furthermore, the through-hole 221 on the insulating component 22 provides space for the installation and positioning of the electrode core 21, ensuring that the electrode core 21 can accurately pass through the through-hole 221 and extend into the receiving cavity 10 while maintaining a stable position.
[0064] Optionally, the insulating member 22 includes a fixed part 222 and an extension part 223 that are connected to each other. The fixed part 222 is fixedly connected to the mounting joint 13; a part of the extension part 223 is located inside the mounting joint 13, and the other part extends into the ball mill jar 1.
[0065] like Figure 2As shown, the insulating component 22 can be composed of two cylindrical pedestals of different diameters. The cylindrical pedestal with a larger diameter is the fixing part 222, which can be fixedly connected to the mounting joint 13 by fasteners to fix the insulating component 22 to the ball mill jar 1. The cylindrical pedestal with a smaller diameter is the extension part 223, the diameter of which is adapted to the diameter of the mounting through hole 130 of the mounting joint 13, so that a part of the extension part 223 can be embedded in the mounting through hole 130, and the other part extends into the receiving cavity 10, that is, the end of the extension part 223 protrudes from the cavity wall of the receiving cavity 10.
[0066] In practical applications, by making the extension 223 protrude from the cavity wall of the receiving cavity 10, the creepage distance between the electrode core 21 and the inner wall of the ball mill jar 1 can be increased, the occurrence of short circuits can be reduced, and the occurrence of problems such as damage to the insulation component 22 and fire can be reduced, thereby reducing costs.
[0067] Optionally, the electrode core 21 includes a head 211 and a rod 212 connected to each other. The head 211 abuts against the insulator 22, and the rod 212 extends into the receiving cavity 10 through the through hole 221.
[0068] Specifically, such as Figure 2 As shown, the head 211 of the electrode core 21 abuts against the fixing part 222 of the insulating member 22 along the second direction Y. There is a certain gap between the outer wall of the rod part 212 and the hole wall of the through hole 221, so that the electrode core 21 can pass through the through hole 221 and extend into the interior of the receiving cavity 10. In this way, the installation between the electrode core 21 and the insulating member 22 can be realized more simply, and the disassembly and replacement of the electrode core 21 is more convenient.
[0069] In some embodiments, the diameter of the through hole 221 is c, the diameter of the rod 212 is d, and the difference between c and d satisfies: 0.2mm≤cd≤0.5mm.
[0070] Specifically, such as Figure 2 As shown, the difference between the diameter c of the through hole 221 and the diameter d of the rod 212 is the size of the gap between the outer wall of the rod 212 and the wall of the through hole 221. If the gap between the outer wall of the rod 212 and the wall of the through hole 221 is too small, the rod 212 will have difficulty passing through the through hole 221 and extending into the receiving cavity 10, increasing the difficulty of installing or removing the electrode core 21. When the grinding material being ground into powder in the ball mill jar 1 is a metal material, such as iron powder, if the gap between the outer wall of the rod 212 and the wall of the through hole 221 is too large, the metal powder will easily enter the gap and come into contact with the rod 212 of the electrode core 21, which may cause a short circuit and lead to problems such as damage to the insulation component 22 and fire, increasing costs.
[0071] In this embodiment, the difference between the diameter c of the through hole 221 and the diameter d of the rod 212 satisfies: 0.2mm≤cd≤0.5mm. This ensures that the gap between the outer wall of the rod 212 and the hole wall of the through hole 221 is moderate. This allows the rod 212 to easily pass through the through hole 221 and extend into the receiving cavity 10, reducing the difficulty of installing or removing the electrode core 21. At the same time, it makes it difficult for metal powder to enter the gap and contact the rod 212 of the electrode core 21, reducing the occurrence of short circuits. This, in turn, reduces the occurrence of problems such as damage to the insulating component 22 and fire, and lowers costs.
[0072] In some alternative embodiments, the ball mill jar 1 is provided with a receiving cavity 10, and the first end 11 is also provided with at least one feed connector 14, which is in communication with the receiving cavity 10.
[0073] Specifically, such as Figure 1 and Figure 3 As shown, the feed connector 14 can be a cylindrical pipe with a feed through hole 140 that communicates with the receiving cavity 10. The grinding media and the material to be ground can be fed into the receiving cavity 10 through the feed connector 14. In this embodiment, by providing the feed connector 14 at the first end 11 of the ball mill jar 1, it is convenient to feed the grinding media and the material to be ground into the receiving cavity 10, ensuring good operability.
[0074] Optionally, it also includes an exhaust element 141, which is disposed at the feed connector 14 and is connected to the feed connector 14.
[0075] like Figure 4 As shown, the exhaust component 141 can be an exhaust pipe or similar structure. The exhaust pipe is connected to the feed connector 14 and an external air extraction device. The external air extraction device can extract the gas inside the receiving cavity 10 through the exhaust pipe, making the receiving cavity 10 a vacuum state, thus preventing the air from reacting with the material to be ground inside the receiving cavity 10 during the grinding process.
[0076] In this embodiment, the exhaust device 141 is installed on the feed connector 14, which facilitates the connection of an external air extraction device with the exhaust device 141 to realize the discharge of gas in the receiving cavity 10 and ensure good operability.
[0077] In some alternative embodiments, there can be two feed connectors 14. The arrangement of two feed connectors 14 can more quickly put the grinding media and the material to be ground into the cavity 10, further ensuring good operability.
[0078] In some alternative embodiments, there may be two exhaust components 141. The arrangement of two exhaust components 141 allows the external air extraction device to be connected to the exhaust component 141 to achieve the discharge of gas in the receiving cavity 10 more quickly, further ensuring good operability.
[0079] Optionally, it also includes a first end cap 3 and a second end cap 4. The ball mill jar 1 includes a third end 15 and a fourth end 16 arranged opposite to each other along the first direction X. The first end cap 3 is fixedly connected to the third end 15, and the second end cap 4 is fixedly connected to the fourth end 16. At least one of the first end cap 3 and the second end cap 4 is provided with a discharge connector 30 at its bottom end along the second direction Y. The discharge connector 30 is in communication with the receiving cavity 10.
[0080] Specifically, as shown in the figure, the ball mill jar 1 includes a third end 15 and a fourth end 16 arranged opposite to each other along the first direction X. The third end 15 and the fourth end 16 are open ends. The first end cover 3 can be fixedly connected to the third end 15 by fasteners, and the second end cover 4 can be fixedly connected to the fourth end 16 by fasteners, so that the ball mill jar 1 can be a closed jar.
[0081] At least one of the first end cap 3 and the second end cap 4 is provided with a discharge connector 30 at its bottom end along the second direction Y. The discharge connector 30 can be a cylindrical pipe, and the discharge connector 30 is provided with a discharge through hole 301 communicating with the receiving cavity 10. The material to be ground after grinding can be taken out from the inside of the receiving cavity 10 through the discharge connector 30. In this embodiment, by providing a discharge connector 30 at the bottom of the first end cap 3 and / or the second end cap 4 of the ball mill jar 1, the material to be ground after grinding in the receiving cavity 10 can be poured or extracted more easily.
[0082] Optionally, an inflation component is also included, which is disposed on the discharge connector 30 and connected to the discharge connector 30. The inflation component can be an inflation pipe, which is connected to the discharge connector 30 and also connected to an external inflation device. The external inflation device can inject protective gas into the receiving cavity 10 through the inflation pipe. The protective gas can prevent air from reacting with the material to be ground in the receiving cavity 10 during the grinding process. In this embodiment, by setting the inflation component on the discharge connector 30, it is easy to connect the external inflation device to the inflation component to realize the filling of protective gas into the receiving cavity 10, ensuring good operability.
[0083] It should be noted that the feed connector 14 and the discharge connector 30 can be sealed by sealing components to make the ball mill jar 1 a closed jar and ensure the normal operation of the ball mill jar 1. The specific structure of the sealing component can be set according to the actual situation, and this application embodiment does not make specific limitations on this.
[0084] It should be noted that the arrangement of the inflation component at the discharge connector 30 can refer to the arrangement of the exhaust component 141 at the inlet connector 14 shown in the attached drawings, which are not specifically shown in the attached drawings of this application.
[0085] In summary, the ball mill jar assembly 100 of this application embodiment may include at least the following advantages:
[0086] In this embodiment, by extending multiple electrode rods 2 into the ball mill jar 1 from the first end 11 arranged along the second direction Y, compared with the prior art installation method of inserting the electrode rods 2 from the side end of the ball mill jar 1 along the first direction X, the length of each electrode rod 2 can be shortened, which can reduce the size of the electrode rod 2 extending into the ball mill jar 1, thereby reducing the occurrence of problems such as electrode rod 2 deformation or occupying a large volume in the ball mill jar 1, and improving the working efficiency of the plasma ball milling device.
[0087] like Figures 5-8 As shown in the figure, this application embodiment also provides a plasma ball milling device, which may specifically include a base, a vibrating element, a driving element, a plasma power supply, and a ball milling jar assembly 100 of any of the above embodiments.
[0088] The volume of the grinding jar 1 in the grinding jar assembly 100 of this application embodiment can be large, so that the plasma ball milling device can be applied to the industrial field.
[0089] It should be noted that in this embodiment, the structure of the ball mill jar assembly 100 is the same as that of the ball mill jar assembly 100 in any of the above embodiments, and its beneficial effects are also similar, so it will not be described in detail here.
[0090] The vibrating element and the driving element are spaced apart on the base. The vibrating element is connected to the ball mill jar assembly 100, and the driving element is connected to the vibrating element. The driving element is used to drive the vibrating element to vibrate, so that the vibrating element drives the ball mill jar 1 to vibrate.
[0091] The base is used to provide a mounting position for the vibrating element and the driving element. The driving element can be a drive motor, which is connected to the vibrating element. The drive motor can drive the vibrating element to vibrate, so that the vibrating element drives the ball mill jar 1 to vibrate.
[0092] The positive electrode of the plasma power supply is connected to the positive electrode of the electrode rod 2, and the negative electrode of the plasma power supply is connected to the body of the ball mill jar 1. Through the plasma power supply and the electrode rod 2, corona discharge or glow discharge is achieved, and plasma is introduced into the interior of the ball mill jar 1 to grind the material to be ground inside the ball mill jar 1.
[0093] In some alternative embodiments, the vibrating element includes a vibration table 5, a driving element connected to the vibration table 5, the vibration table 5 is provided with a groove 51 extending along a first direction X, and the grinding jar 1 of the grinding jar assembly 100 is placed in the groove 51, wherein the groove 51 is arc-shaped.
[0094] Specifically, such as Figure 5 - Figure 8 As shown, the grinding jar 1 is cylindrical. The vibrating components may include a vibration table 5 and multiple buffers. One side of the vibration table 5 is connected to one end of a buffer, and the other end of the buffer is connected to a base. A driving component is connected to the vibration table 5, and the driving component can drive the vibration table 5 and the buffers to vibrate, so that the vibration table 5 drives the grinding jar 1 to vibrate. The buffers may be springs.
[0095] On the other side of the vibration table 5, there is a groove 51 extending along the first direction X. The groove 51 is semi-circular, and the grinding jar 1 is placed in the groove 51. In this embodiment, by making the groove 51 on the vibration table 5 semi-circular to match the shape of the grinding jar 1, the position of the grinding jar 1 can be better fixed, reducing its displacement or shaking during vibration, thereby improving the operational stability of the entire device.
[0096] In some alternative embodiments, at least two clamping members 6 are also included, which are fixedly connected to the vibration table 5 and clamp the ball mill jar 1, wherein the clamping members 6 are arc-shaped.
[0097] Specifically, such as Figure 5 , Figure 7 , Figure 8 As shown, at least two clamping members 6 are spaced apart. Each clamping member 6 includes a semi-circular arc plate and two connecting plates. The two connecting plates are respectively located at both ends of the semi-circular arc plate. The two connecting plates are respectively fixedly connected to both sides of the groove 51 on the vibration table 5 by fasteners or other means. The semi-circular arc plate is clamped to the outer peripheral surface of the ball mill jar 1 by its concave arc surface.
[0098] In practical applications, by setting at least two clamping parts 6, the grinding jar 1 can be more firmly fixed on the vibration table 5, further improving the stability of the device operation.
[0099] It should be noted that the number of clamping parts 6 can be 2, 3, 4, etc., and this application embodiment does not specifically limit this.
