Abstract
Description
Technical Field
[0001] This application relates to the field of ball mill technology, and more particularly to a vibratory ball mill and a plasma ball mill. Background Technology
[0002] A vibratory ball mill is a highly efficient grinding device, commonly used for operations such as crushing, mixing, homogenization, and mechanical alloying. Existing vibratory ball mills typically consist of a vibratory table assembly and a grinding jar. The vibratory table assembly is equipped with two semi-circular clamps, which are connected by fasteners and hold the grinding jar securely to the vibratory table assembly.
[0003] In existing vibratory ball mills, the vibratory table assembly can only accommodate clamps of a single size, and the clamps can only accommodate grinding jars of a single external shape. This means that when the external volume of the grinding jar changes, the vibratory ball mill has difficulty adapting to the change in the external volume of the grinding jar. Utility Model Content

[0014] The first nut is threadedly connected to one of the two threaded rods and contacts the surface of one of the mounting parts facing away from the pressure block; the second nut is fixedly connected to the other of the two threaded rods and contacts the surface of the other mounting part facing away from the pressure block.
[0015] Optionally, at least two second nuts are provided, and the at least two second nuts are spaced apart along the axis of the threaded rod.
[0016] Optionally, the vibration table assembly further includes an anti-slip structure disposed on the surface of the mounting member facing the pressure block.

[0019] Optionally, the vibration table assembly includes a worktable, and the mounting component is located on one side of the worktable; the edge of the worktable away from the mounting component has a grounding structure, which is used for grounding; the pressure block, the mounting component, and the grounding structure are electrically connected, and the pressure block is used to contact the grinding jar to achieve grounding of the grinding jar.
[0020] In a second aspect, embodiments of this application provide a plasma ball mill, the plasma ball mill including a plasma power supply and any of the vibratory ball mills described in the first aspect, the ball milling jar including a jar body and electrodes;
[0021] The tank is connected to the electrode, and at least a portion of the electrode extends into the interior of the tank; the electrode is electrically connected to the plasma power source.

At least two pressure blocks are provided, and the mounting grooves of the at least two pressure blocks enclose a mounting cavity for mounting the grinding jar; that is, the grinding jar is fixed within the mounting cavity enclosed by the at least two pressure blocks. At least two pressure blocks are installed within the mounting space enclosed by the fixing member and the mounting member of the vibratory table assembly, so that the fixing member and the mounting member can be used to position and fix the grinding jar on the vibratory table assembly. Since the mounting member has a connecting structure with at least two connection positions, the fixing member can adjust its position by connecting to different connection positions of the connecting structure, thereby increasing or decreasing the size of the mounting space accordingly. This allows the mounting space to adapt to changes in the shape of the pressure blocks, thus enabling the vibratory ball mill to accommodate pressure blocks of different sizes. Because the vibratory ball mill can accommodate pressure blocks of different sizes, different sized mounting cavities can be formed by replacing the pressure blocks. This allows the vibratory ball mill to be fitted with grinding jars of different sizes, thus enabling the mill to adapt to changes in the external volume of the grinding jars. This allows the vibratory ball mill to be changed to suit different operational needs, effectively improving its working capacity.

[0032] The embodiments of this utility model will now be described in detail. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0033] A vibratory ball mill is a highly efficient powder processing equipment, mainly used for processes such as crushing, mixing, homogenization, and mechanical alloying. It uses high-frequency vibration to generate strong impact, friction, and shear forces on the grinding media (such as steel balls, ceramic balls, etc.) within the mill jar, thereby achieving the crushing and mixing of materials. The mill jar is the container that holds the materials and grinding media, and is usually made of wear-resistant materials (such as stainless steel, ceramic, or polymer materials). The volume and shape of the mill jar are designed according to the characteristics of the materials being processed, and can be cylindrical, square, or other special shapes. The mill jar is usually mounted on the vibrating table assembly of the vibratory ball mill. The vibrating table assembly has excitation devices such as motors, electric cylinders, pneumatic cylinders, hydraulic cylinders, and hydraulic motors, and can vibrate under the drive of these devices, thereby causing the mill jar to vibrate.
[0034] In existing vibratory ball mills, the vibratory table assembly typically features two semi-circular clamps. These clamps are connected by fasteners and hold the grinding jar securely, thus achieving a fixed connection between the grinding jar and the vibratory table assembly. Because the vibratory table assembly and the clamps are fixed together via fasteners, their assembly relationship is singular. Therefore, the vibratory table assembly can only accommodate clamps of a single size. Since the clamps need to be tightened to fit the grinding jar, a single-size clamp can only fit a single-size grinding jar. This means that existing vibratory ball mills are ill-suited to adapting to changes in the shape and volume of the grinding jar. When the shape and volume of the grinding jar change, it is necessary to replace both the clamps and the vibratory ball mill with the appropriate replacements.
[0035] To address the aforementioned problems, this application provides a vibratory ball mill. Specifically, the vibratory ball mill described in this application includes a vibratory table assembly, a fixing component, and a pressure block.
[0036] refer to Figure 1 , Figure 2 The vibration table assembly 1 is the structure used to mount the grinding jar 7 and generate vibration. In this embodiment, the vibration table assembly 1 specifically includes a plate structure. The side of the plate structure facing away from the ground is used to mount the grinding jar 7, and the side of the plate structure facing the ground is used to mount the excitation device. The excitation device is the component that provides vibration to the grinding jar 7 and the vibration table assembly 1. In this embodiment, the excitation device can specifically be a cylinder, electric cylinder, hydraulic cylinder, etc. The power output end of the cylinder, electric cylinder, hydraulic cylinder, etc., is connected to the plate structure of the vibration table assembly 1 for transmission, so that the vibration table assembly 1 is driven to vibrate by the movement of the power output end. Alternatively, the excitation device can be a pendulum rotatably mounted on the plate structure. The pendulum is driven to rotate by a motor, air pump motor, hydraulic motor, etc., so that the vibration table assembly 1 is driven to vibrate by the rotation of the pendulum. In this application, the excitation device can be selected according to actual needs, which will not be elaborated here.
[0037] refer to Figure 1 , Figure 2 The vibration table assembly 1 has two mounting members 11, which are arranged at a distance from each other along a first direction X. Each mounting member 11 has a connecting structure 111, and the connecting structure 111 has at least two connection positions. In this embodiment, the connecting structure 111 can specifically be a groove formed on the mounting member 11, with different positions along its extension direction being different connection positions. Alternatively, the connecting structure 111 can be multiple holes formed on the mounting member 11, with each hole being a different connection position.
[0038] refer to Figure 3 , Figure 4 The fixing element 2 is the structure used to fix the pressure block 4. It can be a rigid structure in the shape of a strip or rod, or a flexible structure such as a chain 21 or rope. The fixing element 2 is connected to the connection position of any of the connecting structures 111, and together with the two mounting elements 11, forms an installation space 3 for installing the pressure block 4. When the pressure block 4 is installed in the installation space 3, the pressure block 4 is simultaneously limited by the fixing element 2 and the two mounting elements 11, so that the pressure block 4 is held within the installation space 3.
[0039] The pressure block 4 is the structure used to hold the grinding jar 7. In this embodiment, at least two pressure blocks 4 are provided, and each pressure block 4 has a mounting groove 41. When at least two pressure blocks 4 are distributed circumferentially, the mounting grooves 41 of the pressure blocks 4 can enclose a mounting cavity 5 for holding and fixing the grinding jar 7. The specific structure of the pressure block 4 and the mounting groove 41 can be determined according to actual needs. For example, the pressure block 4 can be an arc-shaped block with an arc-shaped groove serving as the mounting groove 41. When at least two arc-shaped blocks are distributed circumferentially, the arc-shaped grooves of the arc-shaped blocks enclose a mounting cavity 5 with a circular cross-section. Alternatively, the pressure block 4 can also be a rectangular block with a rectangular groove adapted to the grinding jar 7, serving as the mounting groove 41. When two rectangular blocks are distributed circumferentially, the rectangular grooves of the rectangular blocks enclose a mounting cavity 5 with a rectangular cross-section. The specific number of pressure blocks 4 can be two, three, four, or even more, which will not be elaborated here.
[0040] Since the connecting structure 111 of the mounting component 11 has at least two connection positions, the fixing component 2 can adjust its position by connecting to different connection positions of the connecting structure 111. This allows the size of the mounting space 3 to increase or decrease to correspond to changes in the external dimensions of the pressure block 4, thus enabling the mounting space 3 to accommodate pressure blocks 4 of different external dimensions. This allows the vibratory ball mill to accommodate pressure blocks 4 of different sizes, and consequently, grinding jars 7 of different external dimensions. With the above configuration, the vibratory ball mill can be equipped with grinding jars 7 of corresponding sizes according to different operational needs, thereby effectively improving the working capacity of the vibratory ball mill.
[0041] refer to Figure 3In some embodiments of this application, the mounting member 11 has a first end connected to the fixing member 2 and a second end away from the fixing member 2. The distance between the first ends of the two mounting members 11 along the first direction X is L1, and the distance between the second ends of the two mounting members 11 along the first direction X is L2, where L1 > L2. Specifically, in the embodiments described in this application, the mounting member 11 is specifically two plate-like structures, which are arranged at an angle to each other to form a V-shaped gap. The dimension of the end of this gap connected to the fixing member 2 is L1, and the dimension of the end away from the fixing member 2 is L2, where L1 > L2. The specific dimensions of L1 and L2 can be determined according to actual needs. Preferably, L1 ≥ 261 mm, 0 < L2 ≤ 76 mm. For example, L1 can be 261 mm, 270 mm, or 300 mm, etc.; L2 can be 1 mm, 50 mm, or 76 mm, etc. This ensures that the gap between the two mounting members 11 changes linearly. When the external dimensions of the pressure block 4 change, the two mounting parts 11 can still maintain contact with the pressure block 4 because the interval between the two mounting parts 11 changes linearly, thus achieving the function of holding the pressure block 4. This helps to ensure the adaptability of the vibratory ball mill to pressure blocks 4 of different external dimensions, and thus ensures the adaptability of the vibratory ball mill to grinding jars 7 of different external dimensions.
[0042] Specifically, when the size of the pressure block 4 is relatively large, after it is inserted between the two mounting members 11, its position is relatively closer to the first end of the mounting member 11. When the size of the pressure block 4 is relatively small, after it is inserted between the two mounting members 11, its position is relatively closer to the second end of the mounting member 11. In the embodiments described in this application, preferably, the first end of the mounting member 11 is located above the second end, so that the upper distance of the gap formed by the two mounting members 11 is greater than the lower distance. During installation, the pressure block 4 is placed on the two mounting members 11, and the fixing member 2 is pressed against the surface of the pressure block 4, so that the pressure block 4 is held within the installation space 3 enclosed by the fixing member 2 and the mounting member 11 under the action of friction. Alternatively, the first end of the mounting member 11 is located below the second end, so that the lower distance of the gap formed by the two mounting members 11 is greater than the upper distance. During installation, the pressure block 4 is placed between the two mounting parts 11 and pressed against the surface of the mounting parts 11 by the action of the fixing part 2, so that the pressure block 4 is kept within the installation space 3 formed by the fixing part 2 and the mounting part 11 under the action of friction.
[0043] In some embodiments of this application, the connecting structure 111 optionally includes a connecting groove. The connecting groove is located at the first end of the mounting member 11, and the extending direction of the connecting groove is from the first end of the mounting member 11 to the second end of the mounting member 11. The connecting groove can provide different installation positions for the fixing member 2, which is beneficial for adjusting the position of the fixing member 2, thereby changing the size of the installation space 3 enclosed by the fixing member 2 and the mounting member 11. With the above structure, the size of the installation space 3 can be adjusted according to the size of the pressure block 4, thereby allowing the vibratory ball mill to be adapted to pressure blocks 4 and grinding jars 7 of different shapes and sizes.
[0044] Of course, the connecting structure 111 may also include several holes. The arrangement direction of the several holes points from the first end of the mounting member 11 to the second end of the mounting member 11. The fixing member 2 achieves position adjustment by connecting with different holes.
[0045] In some embodiments of this application, optionally, a pressure block 4 near the fixing member 2 has a receiving groove 42. The fixing member 2 includes a chain 21, and the extending direction of the chain 21 is the same as the extending direction of the receiving groove 42. After the pressure block 4 is installed in the mounting space 3, at least a portion of the chain 21 passes through the receiving groove 42 and contacts the pressure block 4. The chain 21 has good flexibility and can conform as closely as possible to the surface of the pressure block 4 so as to hold the pressure block 4 within the mounting space 3. The receiving groove 42 can prevent the chain 21 from detaching from the pressure block 4, ensuring a reliable installation effect of the pressure block 4 within the mounting space 3. Of course, the fixing member 2 may also include a rope, and the rope can be used to contact the receiving groove 42 of the pressure block 4.
[0046] In the embodiments described in this application, the pressure block 4 near the fixing member 2 can be one, two, three, or even more. For example, when there are two pressure blocks 4, one of the two pressure blocks 4 can be positioned close to the fixing member 2, and the other of the two pressure blocks 4 can be positioned away from the fixing member 2. In this case, the surface of the pressure block 4 close to the fixing member 2 has a receiving groove. As another example, when there are three pressure blocks 4, two of the three pressure blocks 4 can be positioned away from the fixing member 2, and the other of the three pressure blocks 4 can be positioned close to the fixing member 2. In this case, the surface of the pressure block 4 close to the fixing member 2 has a receiving groove.
[0047] In some embodiments of this application, optionally, the fixing member 2 includes a threaded rod 22, a first nut 23, and a second nut 24. Two threaded rods 22 are provided, with their first ends respectively fixedly connected to one end of the chain 21 by welding, bonding, or other methods. Simultaneously, each threaded rod 22 passes through a connecting groove. The first nut 23 is threadedly connected to one of the two threaded rods 22, and when tightened, it contacts the side of the mounting member 11 facing away from the pressure block 4. The second nut 24 is fixedly connected to the other of the two threaded rods 22 by welding, bonding, or other methods, and simultaneously contacts the other side of the mounting member 11 facing away from the pressure block 4. In use, the two threaded rods 22 are first passed through the connecting groove on one of the mounting members 11, so that the chain 21 presses against the pressure block 4. Then, the first nut 23 is tightened, so that the first nut 23 and the second nut 24 are respectively pressed against the surface of the mounting member 11 facing away from the pressure block 4. Since the second nut 24 is fixedly connected to another threaded rod 22, when the first nut 23 is tightened, the second nut 24 can stably abut against the surface of the mounting part 11, providing reliable support and limiting for the chain 21. Under the action of the first nut 23 and the second nut 24, the chain 21 is taut and pressed against the pressure block 4. At this time, the chain 21 and the pressure block 4 form multiple contact points to increase the friction between the chain 21 and the pressure block 4, thereby allowing the pressure block 4 to be reliably held within the mounting space 3.
[0048] refer to Figure 5 In some embodiments of this application, optionally, at least two second nuts 24 are provided along the axis of the threaded rod on which they are located, and the at least two second nuts 24 are spaced apart. In other words, at least two spaced second nuts 24 are fixedly provided on one of the two threaded rods 22. In use, different second nuts 24 can be made to contact the mounting member 11 according to the size of the pressure block 4 and the grinding jar 7, so as to change the size of the mounting space 3, thereby making the mounting space 3 adaptable to pressure blocks 4 of different specifications.
[0049] For example, one of the two threaded rods 22 is fixedly provided with two spaced-apart second nuts 24. One second nut 24 is located at the end of the threaded rod 22, and the other second nut 24 is located in the middle of the threaded rod 22. When the external dimensions of the grinding jar 7 and the pressure block 4 are relatively large, the second nut 24 located at the end can be made to contact the mounting member 11, thereby increasing the length of the part of the fixing member 2 located between the two mounting members 11 to accommodate the increase in the installation space 3. When the external dimensions of the grinding jar 7 and the pressure block 4 are relatively small, the second nut 24 located in the middle of the threaded rod 22 can be made to contact the mounting member 11, thereby reducing the length of the part of the fixing member 2 located between the two mounting members 11 to accommodate the decrease in the installation space 3. It should be noted that the number of second nuts 24 can be determined according to actual needs, specifically two, three, four, or even more. The location of the second nuts 24 is not limited to the end and middle of the threaded rod 22; their location can also be determined according to actual needs.
[0050] refer to Figure 6 In some embodiments of this application, the vibration table assembly 1 may optionally include an anti-slip structure 6. The anti-slip structure 6 is disposed on the surface of the mounting member 11 facing the pressure block 4 and contacts the pressure block 4. This increases the static friction between the mounting member 11 and the pressure block 4, thereby reducing or even preventing relative displacement between the pressure block 4 and the mounting member 11 during the operation of the vibratory ball mill, thus ensuring the reliability of the fixing effect of the mounting member 11 and the fixing member 2 on the pressure block 4 and the ball mill jar 7. In the embodiments described in this application, the anti-slip structure 6 may be a patterned steel plate covering the surface of the mounting member 11 facing the pressure block 4. Specifically, the surface of the patterned steel plate may be provided with wavy or lentil-shaped protrusions to increase the static friction between the mounting member 11 and the pressure block 4. The anti-slip structure 6 may also be a rubber pad covering the surface of the mounting member 11 facing the pressure block 4, the rubber pad having a large surface friction coefficient to increase the static friction between the mounting member 11 and the pressure block 4.
[0051] In some embodiments of this application, optionally, the first end of the mounting member 11 has an opening and a protruding edge 112. The opening communicates with the connecting groove, and the protruding edge 112 extends in the direction away from the pressure block 4. When the fixing member 2 is connected to the connecting groove, the protruding edge 112 provides good limiting for the fixing member 2, preventing it from coming out of the opening during operation. This avoids the fixing member 2 from coming out of the opening and connecting groove due to vibration during the operation of the vibratory ball mill, thus ensuring the retaining effect of the fixing member 2 on the pressure block 4, and consequently ensuring the installation reliability of the ball mill jar 7 on the vibratory ball mill. Specifically, when the fixing member 2 includes a first nut 23, a second nut 24, a threaded rod 22, and a chain 21, when the threaded rod 22 moves to the vicinity of the opening of the connecting groove, the protruding edge 112 can restrict the movement of the first nut 23 and the second nut 24 to prevent the fixing member 2 from coming out of the opening of the connecting groove. In the embodiments of this application, the specific dimensions of the protruding edge 112 can be set according to actual needs, as long as it can prevent the fixing member 2 from coming out of the opening and connecting groove.
[0052] In some embodiments of this application, optionally, at least one pressure block 4 is fixedly connected to the mounting member 11. Specifically, in this embodiment, two pressure blocks 4 may be provided, and the two pressure blocks 4 are arranged vertically along the direction of gravity. The lower pressure block 4 can be fixedly connected to the mounting member 11 by means of fastener connection, welding, bonding, etc. Preferably, the pressure block 4 and the mounting member 11 are connected by fasteners. This can prevent the pressure block 4 from rotating circumferentially relative to the mounting member 11. At the same time, the pressure block 4 can provide circumferential restraint for the upper pressure block 4 to prevent the upper pressure block 4 from rotating axially relative to the mounting member 11. This can ensure that the pressure block 4 has good circumferential restraint, and can prevent the pressure block 4 from rotating circumferentially under the influence of vibration when the vibratory ball mill is working. This is beneficial to ensure the complete restraint of the ball mill jar 7, thereby preventing the ball mill jar 7 from rotating circumferentially during the operation of the vibratory ball mill and affecting normal operation.
[0053] In some embodiments of this application, optionally, the vibration table assembly 1 includes a worktable 13, with the mounting member 11 located on one side of the worktable 13, as shown in the reference. Figure 4The edge of the worktable 13 away from the mounting component 11 has a grounding structure 12, which is used for grounding. The pressure block 4, the mounting component 11, and the grounding structure 12 are electrically connected. At the same time, the pressure block 4 and the grinding jar 7 are electrically connected through direct contact, thereby achieving grounding of the grinding jar 7. Specifically, in this embodiment, the one of the pressure blocks 4 that is in contact with the mounting component 11, the mounting component 11, and the worktable 13 are all made of conductive metals or conductive alloys such as iron, aluminum, and copper. The grinding jar 7 and the pressure block 4, and the pressure block 4 and the mounting component 11 are electrically connected through contact. The mounting component 11 in the vibration table assembly 1 is electrically connected to the grounding structure 12 through the worktable 13. Compared with the grounding method of directly connecting the grounding wire to the grinding jar 7, this can ensure that the grinding jar 7 is stably and reliably grounded using the pressure block 4, the mounting component 11, and the grounding structure 12, which helps to prevent the grinding jar 7 from disconnecting the ground due to vibration. Meanwhile, since the edge of the workbench 13 is far from the mounting component 11 and the grinding jar 7, the amplitude of the vibration in the direction of gravity at this position is relatively small when the grinding jar 7 is running. The grounding structure 12 is located at the edge of the workbench 13, which can reduce the damage to the grounding wire electrically connected to the grounding structure 12 and help ensure the stable grounding of the grounding structure 12.
[0054] Specifically, in this embodiment, two pressure blocks 4 are provided and arranged vertically along the direction of gravity. The lower pressure block 4 is made of conductive metal, while the upper pressure block 4 can be made of materials such as nylon or rubber. The worktable 13 and mounting component 11 in the vibration table assembly 1 are also made of conductive metal. The worktable 13 is provided with a grounding nail that serves as a grounding structure 12, and the grounding nail is connected by a wire to achieve grounding. Static electricity on the grinding jar 7 can be transferred to the grounding structure 12 via the pressure blocks 4, mounting component 11, and worktable 13, and then transmitted to the ground via the wire on the grounding structure 12 to prevent injury to the operator.
[0055] Of course, in other embodiments, the ball mill jar 7 can also be electrically connected to the grounding structure 12 on the workbench 13 by means of a wire connection.
[0056] Secondly, embodiments of this application provide a plasma ball mill, which includes a plasma power source and any of the vibratory ball mills described in the first aspect. In other words, the plasma ball mill is a new generation product iteratively developed based on the vibratory ball mill.
[0057] Specifically, the plasma ball mill includes a plasma power supply. The grinding jar 7 of the plasma ball mill includes a jar body 71 and an electrode 72. The jar body 71 is the structure for accommodating the grinding balls and the powder to be processed. The electrode 72 is mounted on the jar body 71, and at least a portion of the electrode 72 extends into the interior of the jar body 71. The electrode 72 is electrically connected to the plasma power supply. The jar body 71 is filled with a protective gas, typically a stable gas such as nitrogen or helium. When a high voltage is applied to the electrode 72 and the jar body 71, plasma is generated within the jar body 71. Plasma is an ionized gas containing high-energy electrons, ions, active free radicals, and ultraviolet radiation, exhibiting high chemical activity and energy. When plasma bombards the surface of the powder to be processed, it can remove oxides or contaminants from the particle surface, exposing fresh active sites. Simultaneously, plasma can also induce lattice defects such as vacancies and dislocations in the powder to be processed, thereby lowering the energy threshold for mechanical processing such as grinding. The synergistic effect of plasma bombardment and grinding balls significantly improves the material processing efficiency of plasma ball mills. Furthermore, plasma ball mills can also achieve grain refinement and specific functional modifications.
