Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, in particular to a vibration ball mill. Background Art

[0002] In modern industrial production, ball mills, as key equipment for material grinding, are widely used in many fields such as mining, cement, and chemical industry. However, for a long time, ball mills have generally faced severe problems of high energy consumption and low efficiency, which not only restricts the improvement of production efficiency, but also leads to high production costs, which has an adverse impact on the economic benefits and sustainable development of enterprises.

[0003] In-depth exploration of the root cause shows that the inefficiency of the crushing process inside the ball mill is a core factor. Ideally, the grinding body should climb up along the liner in the climbing section of the ball mill, and then fall down after reaching a certain height, relying on its own gravity and impact force to effectively crush the ore. However, in actual operation, this ideal movement mode is difficult to achieve;

[0004] On the one hand, during the climbing stage, the crushed small ores will gradually accumulate under the grinding body. The accumulation of these small ores acts as a buffer, greatly reducing the liner's ability to push the grinding body. The liner cannot provide the grinding body with enough support to climb up smoothly as expected, which in turn affects the height and strength of the grinding body's falling motion;

[0005] On the other hand, small ores have certain rolling characteristics. When the ball mill is running, the rolling of these small ores will drive the grinding bodies above to roll quickly to the bottom of the ball mill. The grinding bodies, which should have been crushed by climbing upward, cannot rise to the appropriate height due to the rolling interference of small ores, making it difficult to effectively carry out the ejection motion. The crushing efficiency of the ball mill is therefore greatly reduced. In order to achieve the required crushing particle size, the grinding cycle has to be extended, further aggravating energy consumption.

[0006] In view of this, this application is hereby filed. Summary of the invention

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1-Figure 9 The present invention provides a technical solution: a vibration ball mill, comprising:

[0047] A vibration machine tool 100 is provided with a grinding assembly 200 for grinding materials, wherein the grinding assembly 200 includes a grinding cylinder and side plates 201 connected to both end surfaces of the grinding end, and the side plates 201 are rotatably arranged on the vibration machine tool 100;

[0048] Among them, the grinding cylinder has an inner cavity for accommodating materials and grinding bodies, and a feed port and a discharge port are respectively arranged at both ends of the grinding cylinder. An inner lining plate 205 is laid on the inner wall of the grinding cylinder, and a movable groove 206 is opened inside the inner lining plate 205. An opening connected to a lifting seat 207 is opened on its inner surface, and a lifting seat 207 is slidably arranged on the inner wall of the opening; one side of the lifting seat 207 extends to the inside of the movable groove 206 and is parallel to the inner wall of the movable groove 206, and the side extending outward protrudes from the inner wall of the inner lining plate 205 and is arranged at an angle to the inner wall of the inner lining plate 205.

[0049] Specifically, in response to the problem of unsatisfactory movement of the grinding body inside the ball mill in the background technology, this structure is expected to improve the movement pattern of the grinding body by setting a slidable lifting seat 207, making it closer to the ideal throwing movement, thereby improving the grinding efficiency and reducing high energy consumption and low efficiency. This design also increases the flexibility of the internal structure of the grinding cylinder, which can better adapt to the grinding needs of different materials.

[0050] See also Figure 6-Figure 9 The lifting seat 207 includes a vertical portion 2071 extending along the length direction of the opening of the movable groove 206, and an inclined portion 2072 is connected to the end of the vertical portion 2071, and a straight portion 2073 is connected to the top of the inclined portion 2072. A blocking portion 2077 is connected to the rear and side of the straight portion 2073. The vertical portion 2071, the inclined portion 2072 and the straight portion 2073 are enclosed by the blocking portion 2077 to form a box structure.

[0051] See also Figure 1 A first screening hole 2076 is formed through the straight portion 2073, a second screening hole 2078 is formed through the rear side wall of the sealing portion 2077, and a second grinding protrusion 2079 extending into the movable groove 206 is provided on the side of the sealing portion 2077 close to the movable groove 206, and a first grinding protrusion 209 extending in the direction of the second grinding protrusion 2079 is provided on the wall surface of the movable groove 206, a grinding channel is formed between the second grinding protrusion 2079 and the first grinding protrusion 209, and discharge holes 208 connected with the movable groove 206 are provided on the wall surfaces of the upper and lower parts of the inner lining plate 205.

[0052] See also Figure 7 and Figure 8 The bottom surface of the vertical portion 2071 is provided with a lower limit portion 2074 extending downward, and the top surface of the straight portion 2073 is provided with an upper limit portion 2075 extending upward. The lower limit portion 2074 and the upper limit portion 2075 are both in contact with the inner wall of the movable groove 206.

[0053] Specifically, the lower limit portion 2074 on the bottom surface of the vertical portion 2071 and the upper limit portion 2075 on the top surface of the straight portion 2073 fit with the inner wall of the movable groove 206. During the rotation of the grinding cylinder, no matter what position the lifting seat 207 is in, these two limit portions can limit the movement range of the lifting seat 207 in the movable groove 206 to ensure that it slides along the predetermined track without deviation or shaking.

[0054] See also Figure 8 and Fig. 9The front end of the straight portion 2073 is also rotatably connected to the folding portion 20710, the free end of the folding portion 20710 is connected to the flexible portion 20712, the inclined portion 2072 is provided with a receiving groove 20711 along its length direction, and the flexible portion 20712 is limitedly slid inside the receiving groove 20711; a driving element is also provided inside the lifting seat 207 for pushing the folding portion 20710 to rotate when the lifting seat 207 is in the lifting position.

[0055] Specifically, during the rotation of the grinding cylinder, when the lifting seat 207 rotates with the cylinder to a specific lifting position, the driving element inside it starts to work. At this time, the driving element pushes the folding portion 20710 to rotate around the connection point with the straight portion 2073, and the flexible portion 20712 connected to the free end of the folding portion 20710 slides within the receiving groove 20711 of the inclined portion 2072. The rotation of the folding portion 20710 changes the movement direction and trajectory of the material and the grinding body, so that a more complex movement path is formed in the grinding cylinder.

[0056] The design of the folding portion 20710 further increases the diversity of the movement trajectories of the material and the grinding body, allowing the material to more fully contact the grinding body in the grinding cylinder, avoiding the problem of local insufficient or excessive grinding, thereby improving the uniformity and efficiency of grinding.

[0057] See also Fig. 9 The driving element includes an electromagnetic block 211 connected to the inner wall of the lifting seat 207, a push rod 212 is slidably installed inside the electromagnetic block 211, one end of the push rod 212 is against the folding portion 20710, and the other end is connected to a limit plate 213, when the push rod 212 slides along the electromagnetic block 211, the folding portion 20710 can be pushed to rotate;

[0058] A fixing sleeve 210 is installed inside the electromagnetic block 211 , and a plurality of permanent magnets 214 are arranged at intervals on the outer wall of the push rod 212 . The plurality of permanent magnets 214 are directly opposite to the fixing sleeve 210 .

[0059] Specifically, the electromagnetic block 211 in the driving element is connected to the inner wall of the lifting seat 207. When the electromagnetic block 211 is energized, a magnetic field is generated, and the push rod 212 slides in the electromagnetic block 211, with one end of the push rod 212 abutting against the folding portion 20710 and the other end connected to the limit plate 213. The fixed sleeve 210 inside the electromagnetic block 211 interacts with the permanent magnet 214 arranged at intervals on the outer wall of the push rod 212. By controlling the current size and direction of the electromagnetic block 211, the magnetic field strength and direction are changed, so that the push rod 212 slides in the electromagnetic block 211 and the folding portion 20710 is pushed to rotate. The electromagnetic drive method has the advantages of fast response speed and precise control. The rotation timing and angle of the folding portion 20710 can be accurately controlled according to the rotation position of the grinding cylinder and the actual grinding situation of the material, so as to achieve precise control of the movement trajectory of the material and the grinding body, and further improve the grinding effect. Compared with other methods such as mechanical drive, the electromagnetic drive structure is relatively simple, easy to maintain and adjust, and reduces the maintenance cost of the equipment.

[0060] See also Figure 5 , grinding cylinder includes,

[0061] The outer cylinder 202 is a cylindrical structure with a hollow interior, and the side plates 201 are fixed at both ends of the outer cylinder 202;

[0062] The inner cylinder 203 is fixed inside the outer cylinder 202, and its outer diameter matches the inner diameter of the outer cylinder 202. The inner wall of the inner cylinder 203 is provided with embedding grooves distributed along its circumference, and the inner lining plate 205 is installed inside the embedding grooves.

[0063] Specifically, the grinding cylinder adopts a double-layer structure of an outer cylinder 202 and an inner cylinder 203. The outer cylinder 202 is a hollow cylindrical cylinder that provides overall support and protection. The side plates 201 are fixed at both ends of the outer cylinder 202 to form a closed space for the grinding cylinder. The inner cylinder 203 is fixed inside the outer cylinder 202, and its outer diameter is adapted to the inner diameter of the outer cylinder 202. The embedded groove on the inner wall of the inner cylinder 203 is used to install the inner lining plate 205. During the grinding process, the outer cylinder 202 and the inner cylinder 203 rotate synchronously, driving the inner lining plate 205 and the internal materials and grinding bodies to move.

[0064] The double-layer structure enhances the strength and stability of the grinding cylinder and can withstand greater grinding forces. At the same time, the design of the inner cylinder 203 embedded in the groove facilitates the installation and replacement of the inner lining plate 205. When the inner lining plate 205 needs to be replaced due to wear, there is no need to disassemble the entire grinding cylinder, thereby reducing the difficulty and cost of maintenance.

[0065] See also Figure 1 and Figure 5 The outer wall of the outer cylinder 202 is threadedly connected with a mounting bolt 204. One end of the mounting bolt 204 extending toward the inner part of the outer cylinder 202 passes through the side wall of the inner cylinder 203 and then extends to the inside of the embedding groove. The inner lining plate 205 is fixed to the embedding groove by the mounting bolt 204.

[0066] Specifically, during the rotation of the grinding cylinder, the mounting bolts 204 ensure that the inner lining plate 205 is tightly connected to the inner cylinder 203 and will not become loose due to vibration or friction, while also facilitating disassembly and replacement thereof.

[0067] See also Figure 1 and Figure 2 , the vibration machine tool 100 includes,

[0068] The base plate 101 is arranged horizontally, and the four corners of the bottom surface thereof are fixedly connected with the first pillars 102, the middle part of the bottom surface thereof is fixed with a vibration motor 106, and the bottom end of the first pillar 102 is connected with the second pillar 103 through a vibration spring 104; the second pillar 103 is fixed to the ground;

[0069] The reinforcing rib 105 is arranged along the length direction of the base plate 101 and fixed between two opposite second pillars 103;

[0070] A set of supports 107 are symmetrically fixedly mounted on the top surface of the base plate 101 . A shaft sleeve 108 is also arranged on the supports 107 , and the side plate 201 is rotatably connected to the shaft sleeve 108 .

[0071] Specifically, the vibration motor 106 generates vibration when working, and the vibration is transmitted to the grinding assembly 200 mounted thereon through the base plate 101. The reinforcing ribs 105 are arranged between two opposite second pillars 103 along the length direction of the base plate 101, thereby enhancing the stability of the machine tool structure. A group of supports 107 on the top surface of the base plate 101 are symmetrically installed, and the shaft sleeves 108 on the supports 107 are rotatably connected to the side plates 201 of the grinding assembly 200, so that the grinding assembly 200 can rotate smoothly on the vibration machine tool 100 and receive vibration.

[0072] The setting of the vibration spring 104 can adjust the frequency and amplitude of the vibration, so that the equipment can adapt to the grinding requirements of different materials. The reinforcing ribs 105 enhance the overall structural strength of the vibration machine 100, ensure the stability of the equipment during operation, reduce the damage to the various components of the equipment caused by vibration, and extend the service life of the equipment. This structural design effectively transmits the vibration to the grinding assembly 200, provides favorable vibration conditions for the grinding process, and helps to improve the grinding efficiency.

[0073] See also Figure 1 , further comprising a drive assembly 300, the drive assembly 300 comprising,

[0074] The support plate 301 is fixed on the top surface of the base plate 101, on which a rotating shaft 302 is rotatably mounted, on which a driving gear 304 is fixedly mounted, and on the outer wall of the outer cylinder 202 a driven gear 303 meshing with the driving gear 304 is fixedly mounted;

[0075] The support platform 305 is fixed on the top surface of the substrate 101 , and a driving motor 306 and a transmission 307 are disposed thereon. One end of the rotating shaft 302 and the driving end of the driving motor 306 are both connected to the transmission 307 .

[0076] Specifically, the driving motor 306 drives the rotating shaft 302 to rotate through the transmission 307, and the driving gear 304 on the rotating shaft 302 is meshed with the driven gear 303 on the outer wall of the outer cylinder 202, thereby driving the grinding cylinder to rotate. The speed of the rotating shaft 302 can be adjusted by the transmission 307, thereby controlling the rotation speed of the grinding cylinder; the driving assembly 300 provides a stable and adjustable power source for the grinding assembly 200, and by accurately controlling the speed of the grinding cylinder, it can meet the speed requirements of different materials and grinding processes, and further improve the grinding efficiency and quality. This transmission structure has a compact design and high transmission efficiency, which can ensure long-term stable operation of the equipment.

[0077] Working principle:

[0078] Equipment architecture and power input:

[0079] Vibration machine 100 and drive assembly 300: The vibration machine 100 is the basic support and vibration generating device of the entire vibration ball mill. The base plate 101 is horizontally arranged. The first pillars 102 at the four corners of the bottom surface are connected to the second pillars 103 fixed to the ground by means of vibration springs 104. The vibration motor 106 in the middle of the base plate 101 generates vibration during operation and transmits it to the grinding assembly 200 through the base plate 101. The reinforcing ribs 105 enhance the stability of the structure of the vibration machine 100. At the same time, the drive assembly 300 provides rotational power for the grinding assembly. The support plate 301 is fixed on the top surface of the base plate 101. The rotating shaft 302 rotates on the support plate 301. The driving gear 304 thereon is meshed with the driven gear 303 on the outer wall of the outer cylinder 202. The driving motor 306 on the support platform 305 drives the rotating shaft 302 through the transmission 307 to drive the grinding assembly 200 to rotate, and the speed of the grinding cylinder can be adjusted by the transmission 307.

[0080] The grinding cylinder of the grinding assembly 200 is composed of an outer cylinder 202 and an inner cylinder 203. The outer cylinder 202 is a hollow cylindrical cylinder structure, with side plates 201 fixed at both ends. The inner cylinder 203 is fixed inside the outer cylinder 202. The embedded groove on the inner wall is used to install the inner lining plate 205. The mounting bolts 204 on the outer wall of the outer cylinder 202 penetrate the side wall of the inner cylinder 203 to fix the inner lining plate 205 in the embedded groove. The two ends of the grinding cylinder are provided with a feed port and a discharge port, and the material and the grinding body enter from the feed port;

[0081] During the grinding process, the grinding cylinder rotates, and the inner lining plate 205 rotates accordingly. The lifting seat 207 in the movable groove 206 in the inner lining plate 205 slides on the inner wall of the opening. The vertical portion 2071 of the lifting seat 207 extends along the length direction of the opening of the movable groove 206. The inclined portion 2072, the straight portion 2073 and the blocking portion 2077 form a box structure, which carries and pushes the material and the grinding body during the rotation process, adjusts the motion state of the grinding body of the ball mill, and enables the grinding body to always perform projectile motion;

[0082] At the same time, when the lifting seat 207 is in the lifting position, its internal driving element works, the electromagnetic block 211 is energized to generate a magnetic field, which interacts with the permanent magnet 214 on the outer wall of the push rod 212, so that the push rod 212 slides, pushes the folding part 20710 to rotate, and the flexible part 20712 slides within the receiving groove 20711 of the inclined part 2072, thereby changing the movement trajectory of the material and the grinding body;

[0083] During the grinding process, the material is pushed by the lifting seat 207, and the first screening hole 2076 of the straight part 2073 and the second screening hole 2078 on the rear side wall of the sealing part 2077 perform preliminary screening on the material. Small-sized material enters through the second screening hole 2078 and enters the movable groove 206. The second grinding protrusion 2079 of the sealing part 2077 and the first grinding protrusion 209 on the wall of the movable groove 206 form a grinding channel, and the small-sized material that has been screened and entered is ground for the second time. Finally, the material is discharged through the discharge hole 208 on the upper and lower walls of the inner lining plate 205, which further improves the grinding efficiency.

[0084] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
