It is mainly composed of a frame, an exciter (including an eccentric block or a vibration motor), a grinding tank (cylinder), a cooling system, grinding media (steel balls, steel rods, etc.) and a control system. The vibration motor or eccentric block drives the grinding tank to generate high-frequency vibration (usually a frequency of 16-20 Hz, an amplitude of 7-14 mm), which drives the grinding media to collide violently with the material, achieving a composite effect of impact, extrusion and friction.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below based on the accompanying drawings and embodiments. The described embodiments are only a part of the embodiments of the present invention, rather than all 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.

[0021] like Figure 1 to Figure 6 As shown, this solution provides a vibrating ball mill system, comprising a longitudinally arranged vibrating table plate 1 and a supporting frame 2, wherein the vibrating table plate 1 and the supporting frame 2 are connected via a vibrating table elastic supporting assembly 3; The vibration table 1 is provided with a vibration motor installation position 101 and a grinding cylinder installation position 102, the grinding cylinder installation position 102 is provided with a grinding cylinder through groove 103 for the grinding cylinder 4 to rotate freely, and grinding cylinder rotating shaft support positions 104 are symmetrically arranged on the left and right sides of the grinding cylinder through groove 103, and the grinding cylinder rotating shaft support positions 104 are provided with a rotating shaft locking assembly 7 that can movably clamp the grinding cylinder rotating shaft 402 at both ends of the grinding cylinder 4; the vibration motor installation position 101 is provided with a vibration motor 8; Any of the grinding drum shafts 402 is connected to the rotation drive module 5 disposed on the support frame 1 via the universal shaft assembly 9. The rotation drive module 5 can drive the universal shaft assembly 9 to drive the grinding drum shaft 402 to rotate clockwise and counterclockwise, thereby indirectly driving the grinding drum to rotate clockwise and counterclockwise, which is convenient for feeding and discharging. The grinding cylinder 4 includes a feed port 401, and a feed hopper 12 corresponding to the feed port 401 is arranged directly above the grinding cylinder 4, so as to facilitate the input of materials into the grinding cylinder 4 through the feed port 401 in the feeding state. A grinding cylinder elastic support assembly 6 corresponding to the feed port 401 is also arranged directly below the grinding cylinder 4, so as to elastically support the feed port when the grinding cylinder is turned over to discharge materials, thereby suppressing random vibration caused by material flow during the discharge process and ensuring smooth discharge.

[0022] Working principle: In the initial state, the feed and discharge ports 401 on the grinding cylinder face upward and correspond to the feed hopper 12 above.

[0023] When feeding, the electromagnetic valve switches on the inlet and outlet ports 401 and the feed hopper 12 are opened to allow the materials to enter the grinding cylinder 4; after the feeding is completed, the electromagnetic valve switches on the inlet and outlet ports 401 and the feed hopper 12 are closed.

[0024] When vibrating the abrasive, the vibration motor 8 installed in any position on the vibration motor installation position 101 is started to convert electrical energy into directional mechanical vibration, thereby driving the vibration table 1 connected thereto and the grinding cylinder 4 movably connected to the vibration table 1 to vibrate at high frequency, and realizing efficient crushing of the material in the grinding cylinder through the energy transfer chain of exciting force-medium-material; after the abrasive is completed, the vibration motor 8 is turned off. It should be noted that the vibration motor 8 in this embodiment can be any one of an eccentric block vibration motor, an electromagnetic vibration motor and a piezoelectric vibration motor. In order to meet the needs of the abrasive, there can also be multiple vibration motors 8, all of which are set in the vibration motor installation position 101 to achieve orderly installation.

[0025] When discharging, the rotation drive module 5 is started to drive the universal shaft assembly 9 to drive the grinding drum 4 to rotate clockwise and counterclockwise until the inlet and outlet port 401 is facing downward and corresponds to the grinding drum elastic support assembly 6 located below; then the solenoid valve on the inlet and outlet port 401 is controlled to open, and the internal material is discharged under the action of gravity. A collection barrel or other device can be set directly below the grinding drum elastic support assembly 6 to collect the processed material.

[0026] It should be noted that, in order to further facilitate the free discharge of materials, a hopper-shaped or conical material guide transition section 403 is provided at the connection between the inlet and outlet port 401 and the grinding cylinder 4, which can better guide the material in the grinding cylinder 4 to the inlet and outlet port 401 during discharge.

[0027] The rotation drive module 5 in the present system includes a motor 501 and a reducer 502 connected to each other, which are connected by a belt, and the reducer is connected to the grinding cylinder shaft 402 through a universal joint assembly 9. The present system uses a universal joint assembly 9 to realize the movable connection between the grinding cylinder 4 and the rotation drive module 5, so that when the grinding cylinder vibrates, the vibration will not be transmitted to the rotation drive module 5, reducing the impact on its life. The universal joint assembly 9 in this embodiment is a double-headed long-axis universal joint.

[0028] As an optimization of the system, a protective bracket 10 capable of sleeve-mounting the vibration table 1 and the grinding drum 4 is provided on the support frame 2, and a feed hopper support frame 11 is provided on the protective bracket 10 to achieve fixed support for the feed hopper 12.

[0029] In the system of this embodiment, the number of the inlet and outlet ports 401 and the corresponding feed hoppers 12 can be increased or decreased according to actual needs.

[0030] like Figure 4 As shown, the vibration table elastic support assembly 3 in this embodiment includes an upper connecting part 301 arranged on the bottom surface of the vibration table plate 1, and a lower connecting part 302 arranged on the surface of the support frame 1, and the upper connecting part 301 and the lower connecting part 302 are connected by an elastic component 303.

[0031] The vibration table elastic support assembly 3 is adjusted in quantity according to the construction requirements. It is located between the vibration table 1 and the support frame 2. It is composed of a multi-directional buffer system with high damping springs. It adopts a progressive spring stiffness design and can absorb different amplitude energies in stages. It also has the following functions during operation: 1. It can attenuate the 30-50Hz high-frequency mechanical shock generated by the vibration table to below 5Hz; 2. It can reduce the vibration transmission rate by 85%, effectively protecting the equipment foundation structure; 3. Ensure that the vibration energy acts on the grinding medium in a directional manner through dynamic balance adjustment; 4. It can extend the service life of motor bearings by about 40% compared with rigid supports.

[0032] The elastic component 303 is any one of a coil spring, an air spring, and a rubber spring, wherein: The helical spring is made of high-strength alloy steel and is formed into an elastic element by winding a spiral metal rod. It is a traditional vibration support device. The air spring is composed of two steel balls forming an airbag inflation gap, and the symmetrical design of the gap between the steel balls balances the axial and radial vibrations. Two independent airbags are connected in parallel to absorb multi-directional vibrations through deformation, thereby improving load adaptability and support balance. A flange is set at the connection between the airbag and the equipment to enhance installation stability and sealing and prevent gas leakage. The rubber spring uses a cylindrical rubber block with a central circular 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, which significantly improves the life and stability. The high damping characteristics of rubber absorb impacts, reduce energy consumption by 15%-20%, and reduce severe vibration when the equipment is started and stopped.

[0033] In addition, you can also choose a combined elastic support component according to your needs, taking into account both life and shock absorption effects.

[0034] like Figure 4 and Figure 5 As shown, in this embodiment, a downward arc-shaped protrusion 105 is provided below the vibration table 1 corresponding to the grinding cylinder shaft support position 6, for strengthening the movable support of the grinding cylinder 4; the arc-shaped protrusion 105 and the vibration table 1 have a keel structure 106.

[0035] The non-uniform vibration of the vibrating table 1 will cause the movement trajectory of the grinding medium to be chaotic. The keel structure is the main load-bearing and force-transmitting skeleton of the vibrating table 1. It disperses the load, suppresses vibration deviation, and ensures efficient transmission of the exciting force through grid or frame design; by balancing the vibration phase difference of each area of ​​the table, it reduces waveform distortion, makes the grinding medium move more regularly, and improves the uniformity of crushing.

[0036] 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.

[0037] like Figure 5 and Figure 6 As shown, the grinding cylinder shaft support 104 in this embodiment is a C-shaped groove having a shape matching the grinding cylinder shaft 402, the grinding cylinder shaft 402 and the C-shaped groove are connected via a shaft bearing, and the grinding cylinder shaft 402 can freely rotate relative to the C-shaped groove; The shaft locking assembly 7 includes a C-shaped sleeve 701 that can be engaged with the C-shaped groove to form an O-shaped sleeve hole. The C-shaped sleeve 701 can be connected to the C-shaped groove by bolts to fix the grinding cylinder shaft 402 in the O-shaped sleeve hole.

[0038] like Figure 7 and Figure 8 As shown, the rotating shaft locking assembly 7 in this embodiment also includes a pressure arm support 702 arranged on the surface of the vibration table 1, and 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 capable of pressing the C-shaped sleeve 701, and the other end is provided with an upper pressure arm slide 707 for sliding a roller trolley 706 connected to the piston end of the pressure arm cylinder 704; The vibration table 1 is also provided with a lower pressure arm slide 708 corresponding to the upper pressure arm slide 707. The lifting and lowering control of the pressure arm 703 can be achieved by sliding the roller trolley 706 in the upper pressure arm slide 707 and the lower pressure arm slide 708.

[0039] 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 be lifted after receiving the upward thrust and rotate relative to the intersection with the pressure arm support 702. The other end of the pressure arm 703 drives the pressure head 705 to move downward to press one side of the C-shaped sleeve 701 so that it is firmly fixed on the C-shaped groove, which can prevent loosening or even displacement during long-term vibration work and ensure the stability of the connection of the grinding cylinder 4.

[0040] It should be noted that a trolley inclined groove 709 is respectively provided on the upper pressure arm slide 707 and the lower pressure arm slide 708, and the inclination angle of the trolley inclined groove 709 is 30° to 60°. The trolley inclined groove 709 of the upper pressure arm slide 707 and the extension line of the trolley inclined groove 709 of the lower pressure arm slide 708 are compared to a point to form an angle.

[0041] The roller trolley 706 includes a push block 710 connected to the piston end of the pressure arm cylinder 704, and an upper roller group 711 and a lower roller group 712 are symmetrically arranged on the push block 710. 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. The opening and closing of the upper pressure arm slide 707 and the lower pressure arm slide 708 are driven by the synchronous driving of the upper roller group 711 and the lower roller group 712.

[0042] like Figures 9 to 12 As shown, the grinding cylinder elastic support assembly 6 in this embodiment includes an upper support plate 601, a middle support plate 602 and a lower support plate 603 arranged vertically, and 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 the axial center position, and 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 and outlet port 401, and falls into the collecting barrel on the lower side through the upper support plate through hole 604, the middle support plate through hole 605 and the lower support plate through hole 606 in sequence; The upper support plate 601 is connected to the middle support plate 602 via a support plate elastic support assembly 607, so that when discharging materials, the upper support plate can elastically support the inlet and outlet ports 401 of the grinding drum 4; The middle support plate 602 is connected to the lower support plate 603 via a support plate support 612; The lower support plate 603 is connected via a crossbeam 201 disposed on the support frame 2 .

[0043] As an optimization of this solution, Fig.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 can support the inlet and outlet ports 401 of the grinding cylinder 4, and the annular lower flange 609 can penetrate the middle support plate through hole 605 under the action of the pressure of the grinding cylinder 4.

[0044] In addition, the upper support plate 601 includes upper support plate right-angled flanges 610 symmetrically arranged on both sides with openings facing downward, and the middle support plate 602 includes middle support plate right-angled flanges 611 symmetrically arranged on both sides with openings facing upward, and the support plate elastic support component 607 is arranged between the upper support plate right-angled flanges 610 and the middle support plate right-angled flanges 611, so as to realize the elastic connection between the upper support plate 601 and the middle support plate 602, thereby realizing the elastic support of the grinding cylinder 4 during discharging.

[0045] The support plate elastic support assembly 607 includes an upper support plate spring support 613 connected to the upper support plate right-angle flange 610 and a middle support plate spring support 614 connected to the middle support plate right-angle flange 611 , and the connection is achieved through a support plate spring 615 .

[0046] The grinding cylinder elastic support assembly 6 in this embodiment has the following functions: (1) It can suppress the random vibration of 2-5mm amplitude caused by material flow during the discharging process; (2) It can ensure that the discharge flow rate is stable within the error range of ±5%; (3) It can prevent the seal from wearing and leaking due to vibration and increase the seal life by 3 times; Through frequency decoupling design, resonance with the main vibration system is avoided.
