Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a vibratory ball mill system. Background Technology

[0002] A vibratory ball mill is a high-efficiency pulverizing device that uses high-frequency vibration to drive grinding media to impact, rub, and shear materials. It mainly consists of a frame, vibrator (including an eccentric block or vibratory motor), grinding jar (cylinder), cooling system, grinding media (steel balls, steel rods, etc.), and control system. The vibratory motor or eccentric block drives the grinding jar to generate high-frequency vibration (typically 16-20 Hz, amplitude 7-14 mm), causing the grinding media to collide violently with the material, achieving a combined effect of impact, compression, and friction. The vibration energy transfer efficiency is 2-5 times that of traditional ball mills, making it particularly suitable for preparing micron- to nano-scale ultrafine powders.

[0003] Chinese utility model patent CN118491625A discloses a dual-excitation dual-rigid-body ball mill, sodium-ion battery cathode material production equipment and process, including an outer rigid body, an inner rigid body, an elastic vibration platform, and two vibration motors. The outer rigid body includes a horizontal grinding cylinder with a feed inlet at the top and a discharge outlet at one end along its axial direction. The inner rigid body includes a stirring blade rotatably disposed inside the grinding cylinder, with the rotation axis of the stirring blade parallel to and offset from the central axis of the grinding cylinder. The elastic vibration platform supports the grinding cylinder, and the two vibration motors are distributed on both sides of the grinding cylinder to drive the grinding cylinder to vibrate. This ball mill is a horizontal ball mill. During installation, the grinding cylinder needs to be pre-fixed to the upper base plate, and then the vibration motors are installed on both sides of the grinding cylinder. During discharge, the material is discharged through the outlet on one side of the grinding cylinder.

[0004] To ensure complete material discharge, the grinding cylinder can be rotated and flipped for feeding. However, this cannot be achieved using the upper base plate structure disclosed in this patent. Furthermore, the installation position of the vibrating motor relative to the grinding cylinder will have different effects on the subsequent vibration of the grinding cylinder and the abrasive material. However, the aforementioned upper base plate structure cannot allow for independent and multi-directional free installation of the vibrating motor, thus affecting the subsequent working effect. On the other hand, the aforementioned double-excitation double-rigid-body ball mill is not only complex in structure and troublesome to install, but also cannot achieve rapid inflow and outflow of large quantities of material, resulting in low working efficiency.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the problems of the prior art and provide a vibratory ball mill system to solve the technical problems that the existing base plate used to install the grinding cylinder cannot adapt to the requirements of the grinding cylinder rotation for feeding materials to achieve the requirements of large batch material fast in and fast out, as well as the compact space, lack of independent installation space for the grinding cylinder and vibratory motor, and the limited installation angle of the vibratory motor, which affects the vibratory abrasive effect.

The vibration table plate is also provided with a lower pressure arm slide corresponding to the upper pressure arm slide. By sliding the roller trolley within the upper pressure arm slide and the lower pressure arm slide, the lifting and lowering control of the pressure arm can be realized.

[0014] Furthermore, the roller trolley includes a push block connected to the piston end of the pressure arm cylinder. The push block is symmetrically provided with an upper roller group and a lower roller group. The upper roller group can act on the trolley inclined groove on the upper pressure arm slide, and the lower roller group can act on the trolley inclined groove on the lower pressure arm slide.

[0015] Furthermore, the grinding cylinder elastic support assembly includes a vertically arranged upper support plate, a middle support plate, and a lower support plate.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0045] like Figures 1-6 As shown, this solution provides a vibratory ball mill system, including a longitudinally arranged vibratory table 1 and a support frame 2, wherein the vibratory table 1 and the support frame 2 are connected by a vibratory table elastic support assembly 3;

[0046] The vibration table plate 1 is provided with a vibration motor mounting position 101 and a grinding cylinder mounting position 102. The grinding cylinder mounting position 102 has a grinding cylinder through groove 103 that allows the grinding cylinder 4 to rotate freely. Grinding cylinder shaft support positions 104 are symmetrically arranged on the left and right sides of the grinding cylinder through groove 103. The grinding cylinder shaft support position 104 is provided with a shaft locking assembly 7 that can movably engage the grinding cylinder shafts 402 at both ends of the grinding cylinder 4. The vibration motor mounting position 101 is provided with a vibration motor 8.

[0047] Any of the grinding cylinder shafts 402 is connected to the rotary drive module 5 mounted on the support frame 1 via the universal joint assembly 9. The rotary drive module 5 can drive the universal joint assembly 9 to rotate the grinding cylinder shafts 402 clockwise and counterclockwise, thereby indirectly driving the grinding cylinder to rotate clockwise and counterclockwise, which facilitates feeding and discharging.

[0048] The grinding cylinder 4 includes an inlet / outlet port 401. A feed hopper 12 corresponding to the inlet / outlet port 401 is provided on the top of the grinding cylinder 4 to facilitate the input of materials into the grinding cylinder 4 through the inlet / outlet port 401 during the feeding process. A grinding cylinder elastic support component 6 corresponding to the inlet / outlet port 401 is also provided on the bottom of the grinding cylinder 4 to provide elastic support for the inlet / outlet port when the grinding cylinder is turned over to discharge materials, thereby suppressing random vibrations caused by material flow during the discharge process and ensuring smooth discharge.

[0049] Working principle:

[0050] In the initial state, the inlet and outlet ports 401 on the grinding cylinder face upwards and correspond to the feed hopper 12 above.

[0051] During feeding, the solenoid valves on the inlet / outlet port 401 and the feed hopper 12 are opened to allow material to enter the grinding cylinder 4; after feeding is completed, the solenoid valves on the inlet / outlet port 401 and the feed hopper 12 are closed.

[0052] During vibratory abrasive grinding, the vibratory motor 8, mounted in any position on the vibratory motor mounting position 101, starts and converts electrical energy into directional mechanical vibration, thereby driving the vibratory table 1 connected to it and the grinding cylinder 4 movably connected to the vibratory table 1 to vibrate at high frequency. Through the energy transfer chain of excitation force-medium-material, efficient pulverization of the material inside the grinding cylinder is achieved. After the grinding is complete, the vibratory motor 8 is turned off. It should be noted that the vibratory motor 8 in this embodiment can be any one of an eccentric block vibratory motor, an electromagnetic vibratory motor, and a piezoelectric vibratory motor. To meet the needs of the abrasive, multiple vibratory motors 8 can be installed, all located on the vibratory motor mounting position 101, to achieve orderly installation.

[0053] During discharge, the rotary drive module 5 is activated, driving the universal joint assembly 9 to rotate the grinding cylinder 4 clockwise and counterclockwise until the inlet / outlet port 401 faces downward and corresponds to the grinding cylinder elastic support assembly 6 located below. Then, the solenoid valve on the inlet / outlet port 401 is opened, and the internal material is discharged under the action of gravity. A collection bucket or other device can be set directly below the grinding cylinder elastic support assembly 6 to collect the processed material.

[0054] It should be noted that, in order to further facilitate the free discharge of materials, a hopper-shaped or cone-shaped material guide transition section 403 is provided at the connection between the inlet / outlet port 401 and the grinding cylinder 4, which can better guide the material in the grinding cylinder 4 to the inlet / outlet port 401 during discharge.

[0055] The rotary drive module 5 in this system includes a motor 501 and a reducer 502 connected to each other via a belt. The reducer is connected to the grinding cylinder shaft 402 via a universal joint assembly 9. This system uses the universal joint assembly 9 to achieve a movable connection between the grinding cylinder 4 and the rotary drive module 5, thus preventing vibration from being transmitted to the rotary drive module 5 when the grinding cylinder vibrates, reducing its impact on lifespan. In this embodiment, the universal joint assembly 9 is a double-headed long-shaft universal joint.

[0056] As an optimization of this system, a protective bracket 10 is provided on the support frame 2 to accommodate the vibrating table 1 and the grinding cylinder 4, and a feed hopper support frame 11 is provided on the protective bracket 10 to achieve fixed support for the feed hopper 12.

[0057] The number of inlet / outlet ports 401 and corresponding feed hoppers 12 in this embodiment system can be increased or decreased according to actual needs.

[0058] like Figure 4 As shown, the vibration table elastic support assembly 3 in this embodiment includes an upper connecting part 301 disposed on the bottom surface of the vibration table plate 1 and a lower connecting part 302 disposed on the surface of the support frame 1. The upper connecting part 301 and the lower connecting part 302 are connected by an elastic member 303.

[0059] The number of elastic support components 3 for the vibrating table is adjusted according to construction requirements. Located between the vibrating table 1 and the support frame 2, it is a multi-directional buffer system composed of high-damping springs. Employing a progressive spring stiffness design, it can absorb energy of different amplitudes in stages. During operation, it also serves the following functions:

[0060] 1. It can attenuate the 30-50Hz high-frequency mechanical shock generated by the vibration table to below 5Hz;

[0061] 2. It can reduce vibration transmission rate by up to 85%, effectively protecting the equipment foundation structure;

[0062] 3. Through dynamic balance adjustment, ensure that vibration energy is directed onto the grinding medium;

[0063] 4. It can extend the service life of motor bearings by about 40% compared to rigid supports.

[0064] The elastic component 303 is any one of a helical spring, an air spring, and a rubber spring, wherein:

[0065] Helical springs are made of high-strength alloy steel and are formed by winding a helical metal rod to create an elastic element. They belong to traditional vibration support devices.

[0066] The air spring consists of an air bladder inflation gap formed between two steel balls. The symmetrical design of the steel ball gap balances axial and radial vibrations. Two independent air bladders are connected in parallel to absorb multi-directional vibrations through deformation, improving load adaptability and support balance. A flange is installed at the connection between the air bladder and the equipment to enhance installation stability and sealing, and prevent gas leakage.

[0067] The rubber spring uses a cylindrical rubber block with a central hole. The static compression is optimized to 1.5-3 times the vertical amplitude, and the ratio of vibration frequency to natural frequency is reduced to 2-4, significantly improving lifespan and stability. The high damping properties of rubber absorb shocks, reducing energy consumption by 15%-20%, while also reducing severe vibrations during equipment start-up and shutdown.

[0068] In addition, modular elastic support components can be selected as needed to balance lifespan and shock absorption.

[0069] like Figure 4 and Figure 5 As shown, in this embodiment, a downward arc-shaped protrusion 105 is provided below the vibration table plate 1 corresponding to the grinding cylinder shaft support position 6, which is used to strengthen the movable support of the grinding cylinder 4; the arc-shaped protrusion 105 and the vibration table plate 1 have a keel structure 106.

[0070] Non-uniform vibration of the vibrating table 1 can cause the grinding media to move in a chaotic trajectory. The keel structure is the main load-bearing and force transmission skeleton of the vibrating table 1. The load is distributed and the vibration offset is suppressed by the grid or frame design, and the excitation force is efficiently transmitted. By balancing the vibration phase difference of each area of ​​the table, the waveform distortion is reduced, the movement of the grinding media is made more regular, and the uniformity of crushing is improved.

[0071] In addition, a sound insulation layer can be embedded in the keel structure to cut off the sound bridge transmission path of vibration through the metal structure and reduce noise leakage.

[0072] like Figure 5 and Figure 6 As shown, in this embodiment, the grinding cylinder shaft support 104 has a C-shaped groove that matches the shape of the grinding cylinder shaft 402. The grinding cylinder shaft 402 and the C-shaped groove are connected by a shaft bearing, and the grinding cylinder shaft 402 can rotate freely relative to the C-shaped groove.

[0073] The rotating shaft locking assembly 7 includes a C-shaped bushing 701 that can engage with the C-shaped groove and form an O-shaped sleeve hole. The C-shaped bushing 701 can be connected to the C-shaped groove by bolts to fix the grinding cylinder rotating shaft 402 in the O-shaped sleeve hole.

[0074] like Figure 7 and Figure 8 As shown, the rotating shaft locking assembly 7 in this embodiment further includes a pressure arm support 702 disposed on the surface of the vibration table plate 1. A pressure arm 703 and a pressure arm cylinder 704 are hinged on the pressure arm support 702. One end of the pressure arm 703 is connected to a pressure head 705 that can press the C-shaped bushing 701, and the other end is provided with an upper pressure arm slide 707 that allows the roller trolley 706 connected to the piston end of the pressure arm cylinder 704 to slide.

[0075] The vibration table 1 is also provided with a lower pressure arm slide 708 corresponding to the upper pressure arm slide 707. By sliding the roller trolley 706 in the upper pressure arm slide 707 and the lower pressure arm slide 708, the lifting and lowering control of the pressure arm 703 can be realized.

[0076] Specifically, the roller trolley 706 is driven forward by the pressure arm cylinder 704. Since the lower pressure arm slide 708 is fixed on the vibration table 1, the upper pressure arm slide 707 will lift after being pushed upward and rotate relative to the junction point with the pressure arm support 702. Then, the other end of the pressure arm 703 drives the pressure head 705 to move downward, pressing one side of the C-shaped bushing 701 and fixing it firmly on the C-shaped groove. This ensures that there will be no loosening or displacement during long-term vibration operation, thus ensuring the stability of the grinding cylinder 4 connection.

[0077] It should be noted that the upper pressure arm slide 707 and the lower pressure arm slide 708 are respectively provided with trolley inclined grooves 709. The inclination angle of the trolley inclined grooves 709 is 30° to 60°. The extension lines of the trolley inclined grooves 709 of the upper pressure arm slide 707 and the trolley inclined grooves 709 of the lower pressure arm slide 708 are at a point, forming an angle.

[0078] The roller trolley 706 includes a push block 710 connected to the piston end of the pressure arm cylinder 704. The push block 710 is symmetrically provided with an upper roller group 711 and a lower roller group 712. The upper roller group 711 can act on the trolley inclined groove 709 on the upper pressure arm slide 707, and the lower roller group 712 can act on the trolley inclined groove 709 on the lower pressure arm slide 708. Through the synchronous drive of the upper roller group 711 and the lower roller group 712, the opening and closing between the upper pressure arm slide 707 and the lower pressure arm slide 708 is realized.

[0079] like Figures 9-12 As shown, the grinding cylinder elastic support assembly 6 in this embodiment includes a vertically arranged upper support plate 601, middle support plate 602, and lower support plate 603. The upper support plate 601, the middle support plate 602, and the lower support plate 603 are respectively provided with an upper support plate through hole 604, a middle support plate through hole 605, and a lower support plate through hole 606 at their axial positions. The upper support plate through hole 604, the middle support plate through hole 605, and the lower support plate through hole 606 are coaxial, so that the material in the grinding cylinder 4 is poured out through the inlet / outlet port 401 and falls into the lower collection bucket in sequence through the upper support plate through hole 604, the middle support plate through hole 605, and the lower support plate through hole 606.

[0080] The upper support plate 601 and the middle support plate 602 are connected by the support plate elastic support assembly 607, so that the upper support plate can provide elastic support for the inlet and outlet ports 401 of the grinding cylinder 4 during material discharge.

[0081] The middle support plate 602 and the lower support plate 603 are connected by a support plate support column 612;

[0082] The lower support plate 603 is connected by a crossbeam 201 mounted on the support frame 2.

[0083] As an optimization of this solution, such as Figure 10 As shown, the surface of the upper support plate 601 is provided with an annular upper flange 608 corresponding to the upper support plate through hole 604, and the bottom surface of the upper support plate 601 is provided with an annular lower flange 609 corresponding to the upper support plate through hole 604; the annular upper flange 608 supports the inlet and outlet port 401 of the grinding cylinder 4, and the annular lower flange 609 can penetrate the middle support plate through hole 605 under the pressure of the grinding cylinder 4.

[0084] Furthermore, the upper support plate 601 includes right-angle flanges 610 with downward openings symmetrically arranged on both sides, and the middle support plate 602 includes right-angle flanges 611 with upward openings symmetrically arranged on both sides. The elastic support assembly 607 is disposed between the right-angle flanges 610 and 611, realizing an elastic connection between the upper support plate 601 and the middle support plate 602, thereby achieving elastic support for the grinding cylinder 4 during material discharge.

[0085] The tray elastic support assembly 607 includes an upper tray spring support 613 connected to the right-angle flange 610 of the upper tray and a middle tray spring support 614 connected to the right-angle flange 611 of the middle tray, and the connection is achieved through a tray spring 615.

[0086] The grinding cylinder elastic support assembly 6 described in this embodiment has the following functions:

[0087] (1) It can suppress random vibrations with an amplitude of 2-5mm caused by material flow during the discharge process;

[0088] (2) It can ensure that the discharge flow rate is stable within ±5% error range;

[0089] (3) It can prevent wear and leakage of the seal due to vibration and increase the seal life by 3 times;

[0090] By using frequency decoupling design, resonance with the main vibration system is avoided.

[0091] The above description is only for illustrating the embodiments of this utility model and is not intended to limit this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
