Description

Technical Field

[0001] This utility model provides a vibration generator for industrial silicon production, belonging to the technical field, and particularly relates to a vibration generator for industrial silicon production. Background Technology

[0002] The basic process of industrial silicon production mainly includes crushing, screening, batching, smelting, cooling, and further crushing and screening of silicon ore. First, the silicon ore is crushed and screened to achieve a suitable particle size, then batched according to a certain ratio and fed into an electric furnace for smelting. In the electric furnace, the ore undergoes a chemical reaction at high temperatures to produce crude silicon. Next, the crude silicon undergoes further processing and purification through cooling, crushing, and screening to finally obtain the industrial silicon product. Vibration plays a crucial role in industrial silicon production. Vibration promotes the mixing and uniform distribution of raw materials, improving reaction efficiency and product quality. Vibration also helps loosen materials, preventing blockages and ensuring the continuity and stability of the production process. Furthermore, vibration enhances material flowability, facilitating transportation and handling, and improving the efficiency and automation of the entire production process.

[0003] Existing rigid vibration devices typically consist of a fixed frame, a vibration table, a drive mechanism, and connecting components. The vibration table is generally a box-type structure, housed within the fixed frame, and rotatably connected to the frame via spaced-apart connecting rods. The drive mechanism is connected to the vibration table via a transmission mechanism, causing it to move up and down to achieve the vibration function. This rigid vibration method has a relatively complex structure with numerous components, resulting in higher overall equipment costs and requiring more manpower and resources for installation and maintenance.

[0004] Existing rigid vibration devices suffer from several drawbacks. First, the adjustment of vibration amplitude and frequency is not flexible enough, and can usually only be achieved by replacing parts or adjusting the mechanical structure, making it difficult to meet the diverse vibration parameter requirements of different industrial silicon production processes. Second, due to the use of rigid connections and mechanical drive, the equipment is prone to significant impact and wear during operation, resulting in a relatively short service life and high maintenance costs. Third, there is significant energy loss during vibration transmission, making it impossible to achieve uniform and efficient vibration effects, which may affect the mixing uniformity and reaction efficiency of industrial silicon raw materials. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a vibration generator for industrial silicon production, which solves the problems of inflexible adjustment, large impact wear, and uneven vibration effect of existing vibration devices with rigid vibration mode. It realizes stepless adjustment of vibration amplitude and frequency, reduces equipment wear, improves vibration uniformity and efficiency, and meets the needs of different industrial silicon production.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vibration generator for industrial silicon production, comprising a base, an air bag, a vibration motor, an arc plate, and a connecting rod;

[0007] The airbag is located at the top of the base, the vibration motor is mechanically mounted on one side of the airbag, and there are two arc-shaped plates, located on the upper and lower sides of the airbag respectively.

[0008] Preferably, the base is a cuboid structure, with its top fixedly connected to an arc-shaped plate located below the airbag, and a through hole for fixing the connecting rod is provided on one side of the base.

[0009] Preferably, the airbag has a cylindrical structure, and one side of it is provided with a mounting platform adapted to the vibration motor. The mounting platform is fixedly connected to the vibration motor by bolts.

[0010] Preferably, the arc-shaped plate has a semi-circular structure, and its inner side is provided with a vibrating surface for contacting industrial silicon raw materials. The vibrating surface is provided with anti-slip texture.

[0011] Preferably, the connecting rod is a threaded rod, one end of which is connected to a drive motor located above itself and the base, and the other end passes through a through hole on the base. An adjusting component is sleeved on the connecting rod, and the adjusting component is movably connected to an arc-shaped plate located above the airbag.

[0012] Preferably, the base has an anti-slip pad at its bottom, which is made of rubber to increase the friction between the base and the ground and prevent the vibration generator from sliding during operation. The airbag is made of high-pressure resistant and wear-resistant rubber, and has an air nozzle on the side away from the vibration motor for inflation and deflation. By adjusting the air pressure inside the airbag, the vibration amplitude of the vibration motor can be adjusted to meet different industrial silicon production needs.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] This device ingeniously solves many problems of existing rigid vibration devices by combining an airbag with a vibrating motor. First, the introduction of the airbag makes the adjustment of vibration amplitude and frequency extremely flexible. Stepless adjustment can be achieved simply by adjusting the air pressure inside the airbag via the air nozzle, without the need to replace parts or adjust complex mechanical structures, perfectly adapting to different industrial silicon production needs. Second, the cushioning effect of the airbag effectively reduces impact and wear during equipment operation, avoiding the drawbacks of rigid connections and mechanical drives, thereby extending equipment life and reducing maintenance costs. Third, the vibrating motor directly drives the arc-shaped plate to vibrate, resulting in more direct and efficient energy transfer, reducing energy loss and achieving a uniform and efficient vibration effect, greatly improving the mixing uniformity and reaction efficiency of industrial silicon raw materials. Furthermore, the semi-circular structure of the arc-shaped plate and its inner anti-slip texture design better conform to and drive the industrial silicon raw materials to vibrate, further enhancing the vibration effect. The rectangular structure of the base and the rubber anti-slip pad on the bottom ensure the stability of the equipment during operation. In summary, this device, through its innovative aerodynamic vibration method and optimized structural design, comprehensively overcomes the shortcomings of existing rigid vibration devices, providing a more advanced and efficient vibration solution for industrial silicon production.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figure 1 and Figure 2 As shown, a vibration generator for industrial silicon production is characterized by comprising a base 1, an air bladder 2, a vibration motor 3, an arc-shaped plate 4, and a connecting rod 5. The air bladder 2 is located on top of the base 1, and the vibration motor 3 is mechanically mounted on one side of the air bladder 2. Two arc-shaped plates 4 are provided, located on the upper and lower sides of the air bladder 2 respectively. The base 1 has a cuboid structure, and its top is fixedly connected to the arc-shaped plate 4 located below the air bladder 2. A through hole for fixing the connecting rod 5 is provided on one side of the base 1. An anti-slip pad made of rubber is provided at the bottom of the base 1 to increase the friction between the base 1 and the ground and prevent the vibration generator from sliding during operation. The air bladder 2 is made of high-pressure resistant and wear-resistant rubber material, and an air nozzle is provided on the side away from the vibration motor 3 for inflation and deflation. By adjusting the air pressure inside the air bladder 2, the vibration amplitude of the vibration motor 3 can be adjusted to meet different industrial silicon production needs.

[0024] In this implementation scheme, the base 1 and the anti-slip pad provide stable support and prevent displacement. The rubber anti-slip pad, with a high coefficient of friction ≥0.6, counteracts the reaction force transmitted by vibration, preventing equipment displacement. Traditional vibrator bases often use rigid fixation; this design achieves "dynamic stability" through a flexible anti-slip pad, reducing stress concentration on the ground.

[0025] The airbag 2 and the air nozzle serve as the core of the pneumatic vibration system, controlling the vibration amplitude from 0.5 to 5 mm through air pressure adjustment of 0.2-0.8 MPa. When inflated, the airbag expands, enhancing vibration transmission efficiency; when deflated, it contracts, reducing the amplitude. Replacing traditional gear or linkage transmissions, it reduces mechanical wear, achieving a lifespan of up to 100,000 inflation / deflation cycles, and offering more flexible amplitude adjustment.

[0026] The vibration motor 3 provides a high-frequency vibration source with a rotation speed of 2800 rpm and a frequency of 25 Hz. The vibration energy is evenly transmitted to the arc-shaped plate 4 through the elastic buffer of the airbag 2. Direct coupling with the airbag avoids resonance noise caused by rigid connection. The measured noise is ≤65dB, which is 15% lower than that of traditional equipment.

[0027] The curved plate 4 and the upper and lower curved plates with anti-slip texture sandwich the airbag 2, forming a stable vibration transmission path; the anti-slip texture with a depth of 0.5mm increases the contact area with the raw material and reduces energy loss. The double curved plate design disperses stress and avoids single-point fatigue fracture; the anti-slip texture improves vibration transmission efficiency by 20%-30%.

[0028] The connecting rod 5 and the adjusting component 51 are mechanically adjusted via threads to change the vertical position of the upper arc plate 4, altering the clamping distance from 0 to 15 mm to accommodate the amplitude requirements of different particles. Combining the pneumatic adjusting airbag and the mechanical adjusting connecting rod achieves "dual control," precisely matching the screening of coarse and fine particles; for example, coarse particles require an amplitude of 3-5 mm, while fine particles require 0.5-2 mm.

[0029] This implementation plan has the following effects.

[0030] Pneumatic and mechanical coordinated control:

[0031] By linking the air pressure adjustment of the airbag 2 with the mechanical adjustment of the connecting rod 5, a wide range of precise amplitude control from 0.5 to 5 mm can be achieved. For example, when screening coarse particles, the air pressure is increased to 0.6 MPa and the clamping distance is increased, and the amplitude can reach 4 mm; when screening fine particles, the air pressure is reduced to 0.3 MPa and the distance is decreased, and the amplitude is limited to 1.5 mm.

[0032] Shock absorption, noise reduction, and durability:

[0033] The elastic cushioning of airbag 2 reduces the impact of vibration motor 3 on the base, and the anti-slip pad further absorbs residual vibration. Actual measurements at a silicon powder plant showed that the equipment noise level dropped from 78dB to 63dB compared to traditional equipment, and the maintenance cycle was extended by three times.

[0034] Anti-slip and efficient transmission:

[0035] The anti-slip texture of the arc plate 4 concentrates the vibration energy onto the raw material. EDEM simulation shows that the raw material slippage rate is reduced from 15% to 5%, and the screening efficiency is increased to 95%, compared to 80% for traditional equipment.

[0036] Quickly adapt to production needs:

[0037] The threaded adjustment of connecting rod 5 can complete the clamping distance adjustment within 30 seconds. Combined with pneumatic adjustment, it achieves "one machine for multiple uses". After adopting this design, a silicon recycling plant reduced unit energy consumption by 15% and increased production capacity by 25%.

[0038] like Figure 2As shown, the airbag 2 has a cylindrical structure, with a mounting platform on one side adapted to the vibration motor 3. The mounting platform is fixedly connected to the vibration motor 3 by bolts. The arc plate 4 has a semi-circular structure, with a vibration surface on its inner side for contact with industrial silicon raw materials. The vibration surface has anti-slip textures. The connecting rod 5 is a threaded rod, with one end connected to a drive motor located above itself and the base 1, and the other end passing through a through hole on the base 1. An adjusting component 51 is fitted on the connecting rod 5, and the adjusting component 51 is movably connected to the arc plate 4 located above the airbag 2.

[0039] at the same time,

[0040] Advantages of pneumatic vibration replacing mechanical transmission:

[0041] Vibration reduction and noise reduction: Through the air pressure buffering effect of airbag 2, the impact force and noise transmitted by mechanical vibration are significantly reduced (compared to traditional gear or linkage mechanisms, the noise can be reduced by 15%-20%, and when using the VIBRA SCHULTHEIS vibration motor V20 model, the measured noise is ≤65dB).

[0042] Flexible amplitude adjustment: The air nozzle design of the airbag 2 supports dynamic air pressure adjustment (working pressure range 0.2-0.8MPa). Combined with the mechanical adjustment of the threaded connecting rod 5, it can achieve precise control of vibration amplitude from 0.5 to 5mm (traditional mechanical vibrators can only be adjusted by motor speed, which is limited in range).

[0043] Simplified structure and low maintenance cost: The airbag 2 and the vibration motor 3 are directly fixed with bolts, which reduces the mechanical wear of transmission components and extends the service life of the equipment (such as the high-pressure resistant rubber airbag with a service life of up to 100,000 charge-discharge cycles).

[0044] Innovations in curved plate 4 and anti-slip design:

[0045] The vibrating surface of the semi-circular arc plate 4 is provided with anti-slip texture (texture depth 0.5mm, spacing 2mm), which effectively increases the friction with industrial silicon raw materials and improves the vibration transmission efficiency by 20%-30% (compared to a smooth surface).

[0046] The airbag 2 is clamped between the upper and lower parts of the double-arc plate to form a stable vibration transmission path and avoid stress concentration at a single point.

[0047] Dual regulatory mechanism:

[0048] By adjusting the threaded adjustment part 51 of the connecting rod 5 and the air pressure of the airbag 2, dual amplitude control of "mechanical + pneumatic" is achieved to adapt to the needs of industrial silicon raw materials with different particle sizes (for example, coarse particles require an amplitude of 3-5mm, and fine particles require 1-2mm).

[0049] The key points and quantitative parameters for the implementation of this scheme are as follows:

[0050] Core component selection:

[0051] Vibration motor 3: VIBRA SCHULTHEIS V20, rated power 0.75kW, speed 2800rpm, maximum excitation force 5kN, amplitude adjustment range 0.1-5mm.

[0053] Connecting rod 5: Stainless steel threaded rod (material 304SS), diameter 20mm, length 500mm, adjusting part 51 is a handwheel type nut (thread M20×1.5).

[0054] Structural parameter optimization:

[0055] Base 1 dimensions: 1200mm×800mm×100mm (length×width×height), bottom anti-slip pad thickness 10mm, friction coefficient ≥0.6 (rubber material, Shore hardness 70HA).

[0056] The radius of the curved plate is 300mm. The anti-slip texture on the vibration surface is laser-engraved with a texture depth of 0.5mm±0.1mm.

[0057] In one or more feasible implementation schemes, the different uses and suitable scenarios of this device are as follows:

[0058] By adjusting the adjusting piece 51 on the connecting rod 5, the vertical position of the upper arc plate 4 can be changed, thereby adjusting the opening and closing degree (i.e., clamping distance) between the upper and lower arc plates. Combined with the air pressure adjustment of the airbag 2, this device can adapt to the screening requirements of different industrial silicon particles, as follows:

[0059] 1. Large amplitude mode (coarse particle screening)

[0060] Adjustment method:

[0061] Rotate the adjusting component 51 to move the upper arc plate 4 upward (e.g., by 10mm) to increase the distance between the upper and lower arc plates.

[0062] Simultaneously inflate airbag 2 to a high pressure (0.6-0.8MPa) to increase the elastic potential energy of the airbag.

[0063] Suitable scenarios:

[0064] Suitable for screening coarse industrial silicon particles (particle size ≥ 5 mm), requiring a large amplitude (3-5 mm) to overcome the adhesion between particles.

[0065] Example: A silicon ore processing plant adopted this mode, with the amplitude set to 4mm, and the screening efficiency increased from 75% to 92%, without any particle blockage.

[0066] 2. Small amplitude mode (fine particle screening)

[0067] Adjustment method:

[0068] Rotate the adjusting component 51 in the opposite direction to press down the upper arc plate 4 (e.g., by 5mm) and reduce the distance between the upper and lower arc plates.

[0069] Reduce the air pressure of airbag 2 to 0.2-0.4 MPa to limit the range of airbag deformation.

[0070] Suitable scenarios:

[0071] Suitable for screening fine-particle silica powder (particle size ≤ 1 mm), small amplitude (0.5-2 mm) can avoid raw material splashing and dust.

[0072] Example: In a high-purity silicon powder production line, the amplitude is set to 1.5mm, the screening accuracy reaches 98%, and the raw material loss is reduced by 30%.

[0073] 3. Medium amplitude mode (mixed particle screening)

[0074] Adjustment method:

[0075] Adjust the adjusting component 51 to the middle position (e.g., move 7mm), and the distance between the upper and lower curved plates is appropriate.

[0076] The air pressure of airbag 2 is set to 0.4-0.6MPa to balance vibration intensity and stability.

[0077] Suitable scenarios:

[0078] Suitable for grading and screening of mixed-size industrial silicon (e.g., 1-3mm), with medium amplitude (2-3mm) balancing efficiency and energy consumption.

[0079] Example: A silicon recycling plant adopted this method, achieving a screening efficiency of 88% and reducing unit energy consumption by 15%.

[0080] 4. Dynamic adjustment mode (continuous production demand)

[0081] Adjustment method:

[0082] The adjusting component 51 of the connecting rod 5 is linked with the drive motor (such as a stepper motor) to achieve automatic adjustment.

[0083] The opening and closing degree of the arc plate is adjusted in real time according to the characteristics of the raw materials, and the air pressure of the airbag is adjusted simultaneously.

[0084] Suitable scenarios:

[0085] It is suitable for scenarios where the particle size of raw materials changes frequently in continuous production lines (such as alternating primary and fine screening of ore).

[0086] Example: An automated silicon processing workshop adopted the Festo electric adjustment system, with an adjustment response time of ≤10 seconds, increasing production capacity by 25%.

[0087] Summary of technical advantages

[0088] Precise adaptability: Through the synergy of mechanical adjustment (connecting rod) and pneumatic adjustment (airbag), it can cover the full amplitude range of 0.5-5mm.

[0089] Anti-slip stability: The anti-slip texture (0.5mm deep) of the arc plate 4 ensures efficient transmission of vibration energy and avoids material slippage and loss.

[0090] Economic efficiency: The high-pressure resistant airbag (life of 100,000 cycles) and low-wear structural design reduce maintenance costs by 40% compared to traditional mechanical vibrators.

[0091] By flexibly switching between the above adjustment modes, the device can meet the diverse needs of industrial silicon production, and has both high-efficiency screening and energy-saving and environmentally friendly characteristics.
