TECHNICAL FIELD

[0001] The utility model relates to diamond micro powder processing technical field, concretely is a kind of diamond micro powder ultrasonic oscillation uniform dispersion device. BACKGROUND

[0002] In modern industry and scientific research applications, diamond micro powder is widely used in various precision machining, grinding and polishing and as an additive to improve the performance of composite materials due to its excellent physical and chemical properties. In order to ensure the effectiveness of these applications, diamond micro powder needs to be uniformly dispersed in a specific liquid medium to form a stable suspension. This process is not only crucial to product quality, but also directly affects the performance and service life of the final product.

[0003] Although some existing dispersion devices can achieve preliminary dispersion of diamond micro powder, in actual operation, a large amount of insufficiently dispersed micro powder particles can easily deposit at the bottom of the container, resulting in significant uneven dispersion. Moreover, the ultrasonic generator in traditional dispersion devices is usually fixedly installed, and the vibration energy generated is not uniformly distributed, making it difficult to cover the entire liquid medium. This limitation is more pronounced for larger volume containers, affecting the uniform distribution of diamond micro powder in the entire system and limiting the quality and efficiency of subsequent processes. SUMMARY

[0004] The utility model aims at providing a kind of diamond micro powder ultrasonic oscillation uniform dispersion device to solve the problem of uneven dispersion and easy deposition of current diamond micro powder dispersion device proposed in the above background art.

[0009] Preferably, the center of the turbulence ring is provided with a connecting sleeve sleeved outside the bottom end of the central shaft, and the turbulence plate and the bellows are staggered and connected between the inner wall of the turbulence ring and the outer wall of the connecting sleeve.

[0010] Preferably, the surface of the disturbance plate is provided with a strip groove with a wavy structure, and both ends of the corrugated pipe are connected to the inner wall of the disturbance ring and the outer wall of the sleeve through elastic bands.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: This ultrasonic oscillation uniform dispersion device for diamond micropowder achieves superior all-round coverage and uniform distribution of ultrasonic energy, effectively preventing the deposition of diamond micropowder, significantly improving dispersion efficiency and uniformity, thereby enhancing product quality. The device utilizes a pre-adjustment mechanism at the top of the ultrasonic transducer support, composed of a sleeve and mounting plate. This pre-adjustment mechanism flexibly adjusts the position of the ultrasonic transducer unit via a fixed ring and a pull rod, ensuring optimal working conditions.

[0017] 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.

[0018] Please see Figures 1-4This utility model provides a technical solution: a diamond micro-powder ultrasonic oscillation uniform dispersion device, including a sealed container 1. The sealed container 1 has a feed inlet at the top and a sealable door that can be opened and closed on the outside. A drive motor 2 is fixedly installed at the bottom of the sealed container 1 by bolts. A central shaft 3 is located at the center of the interior of the sealed container 1. The bottom end of the central shaft 3 is connected to the inner wall of the bottom end of the sealed container 1 by a bearing. The output end of the drive motor 2 is connected to the bearing at the bottom end of the central shaft 3. Ultrasonic transducer supports composed of sleeves 4 and mounting plates 5 are provided at the upper and lower ends of both sides of the central shaft 3. The inner end of the sleeve 4 is welded and fixed to the connection of the central shaft 3. The mounting plate 5 is located on the outside of the sleeve 4. A movable block 6 is provided inside the mounting plate 5. The bottom of the movable block 6... The unit is equipped with an ultrasonic transducer unit 7, which adopts a high-frequency vibrating piezoelectric ceramic transducer structure, model PZT-8. A protective cover is fixedly installed on the outside of the ultrasonic transducer unit 7. The protective cover is made of transparent, high-strength, corrosion-resistant material, which protects the internal components from external contamination without obstructing the observation of the device's operation. The top of the sleeve 4 and mounting plate 5 is equipped with a pre-adjustment mechanism consisting of a fixed ring 8 and a pull rod 9. Furthermore, the bottom of the sealed container 1 is equipped with a turbulence ring 12 that rotates synchronously via a central shaft 3. The turbulence ring 12 contains a composite turbulence mechanism consisting of several turbulence plates 13 and bellows 14. This pre-adjustment mechanism, consisting of the fixed ring 8 and pull rod 9, can pre-adjust each ultrasonic transducer unit. The ultrasonic transducer 7 is adjusted to a suitable position inside the sealed container 1. When the drive motor 2 drives the central shaft 3 to rotate inside the sealed container 1, the ultrasonic transducer support composed of the sleeve 4 and the mounting plate 5 moves synchronously, causing each ultrasonic transducer unit 7 to start working. In this way, the vibration energy generated by the ultrasonic transducer unit 7 can more evenly cover the entire liquid medium. Especially for larger containers, this overcomes the limitation of uneven energy distribution caused by the fixed installation of ultrasonic generators in the prior art, achieving all-round coverage of ultrasonic energy and improving the uniformity of diamond micro powder distribution in the sealed container 1. At the same time, the turbulence ring 12 also rotates with the central shaft 3, and the composite turbulence mechanism inside the turbulence ring 12 operates accordingly, that is, several turbulence plates 13 and... The bellows 14 generates complex hydrodynamic effects during rotation. This coordinated action creates strong turbulence in the liquid medium within the sealed container 1, effectively preventing diamond powder from depositing at the bottom of the container. This solves the problem of uneven dispersion caused by the accumulation of insufficiently dispersed powder particles at the bottom of traditional dispersion devices. The fixed ring 8 is welded to the top of the outer end of the sleeve 4, and the pull rod 9 is horizontally fixed to the top of the mounting plate 5. The outer end of the pull rod 9 is welded to the top of the mounting plate 5 via a connecting block, and the inner end of the pull rod 9 slides through the inside of the fixed ring 8. The fixed ring 8 is also connected to a locking screw via a threaded structure. When the position of the ultrasonic transducer unit 7 needs to be adjusted, the operator can loosen the locking screw on the fixed ring 8.The inner end of the pull rod 9 slides within the fixed ring 8, thereby flexibly changing the position of the ultrasonic transducer unit 7 for pre-adjustment. Once the optimal position is found, the locking screw is tightened again to securely lock the pull rod 9 within the fixed ring 8, ensuring that the ultrasonic transducer unit 7 will not shift during operation. A take-up and release shaft is welded to one end of the mounting plate 5 connected to the sleeve 4, and the sleeve 4 has a take-up and release hole that mates with the take-up and release shaft. A sealing ring is provided at the edge of this take-up and release hole. This structure ensures the stability and reliability of the structure by simultaneously causing the take-up and release shaft to slide within the take-up and release hole in the sleeve 4 when the operator moves the mounting plate 5. The sealing ring at the edge of the take-up and release hole in the sleeve 4 ensures the stability and reliability of the structure. The close cooperation between the components prevents external impurities from entering the interior during adjustment. The mounting plate 5 has an internal movable opening 10, and both sides of the movable block 6 are connected to the inner walls of the movable opening 10 via elastic elements 11. An elastic ring, matching the structure of the movable block 6, is located at the bottom edge of the movable opening 10. When the ultrasonic transducer unit 7 starts working and vibrates, the movable block 6 vibrates at high frequency under the drive of the ultrasonic transducer unit 7. The elastic element 11 acts as a buffer and reset element, ensuring that the movable block 6 maintains a stable position during vibration and effectively transmits vibration energy. The elastic ring further enhances the connection between the movable block 6 and the bottom edge of the movable opening 10. The sealing and stability between the openings prevent any possible displacement or loosening during vibration, ensuring that the ultrasonic transducer unit 7 can efficiently transfer vibration energy to the liquid medium. A connecting sleeve 15, fixedly sleeved outside the bottom end of the central shaft 3, is located at the center of the turbulence ring 12. The turbulence plate 13 and the bellows 14 are staggered and connected between the inner wall of the turbulence ring 12 and the outer wall of the connecting sleeve 15. This structure of the connecting sleeve 15 ensures a stable connection between the turbulence ring 12 and the central shaft 3, enabling the entire composite turbulence mechanism to operate stably. Furthermore, through their staggered design, the turbulence plate 13 effectively cuts and guides the liquid flow, while the bellows 14... The tube 14 further enhances the turbulence effect. The combined effect of the two components creates strong, multi-directional turbulence within the sealed container 1. The surface of the disturbance plate 13 has a wavy, strip-shaped groove, and both ends of the bellows 14 are connected to the inner wall of the disturbance ring 12 and the outer wall of the connecting sleeve 15 via elastic bands. This structure allows the wavy, strip-shaped grooves on the surface of the disturbance plate 13 to effectively cut and guide the liquid flow, increasing the degree of turbulence while reducing resistance to flow. This makes the liquid medium easier to disturb and disperse. The bellows 14 maintains elastic tension during rotation, allowing for slight deformation with fluid movement, further promoting fluid mixing and uniform distribution.

[0019] Working Principle: When using this diamond micro powder ultrasonic oscillation uniform dispersion device, first open the device through the sealed door outside the sealed container 1. Then, the operator pre-adjusts the position of the ultrasonic transducer unit 7 according to actual needs. By loosening the locking screw on the fixed ring 8, the inner end of the pull rod 9 slides inside the fixed ring 8. When moving the mounting plate 5, the take-up and release shaft slides in the take-up and release hole inside the sleeve 4 to flexibly change the position of the ultrasonic transducer unit 7. After finding the optimal position, tighten the locking screw again to firmly lock the pull rod 9. After adjustment, close the sealed door outside the sealed container 1 and add the liquid to be processed and diamond micro powder through the feed port. Then start the drive motor 2. The output end of the drive motor 2 drives the central shaft 3 to rotate. The ultrasonic transducer unit 7, composed of the sleeve 4 and the mounting plate 5, rotates through the central shaft 3. The ultrasonic transducer support moves synchronously, causing each ultrasonic transducer unit 7 to start working. The vibration energy generated by the ultrasonic transducer unit 7 is transmitted to the liquid medium through the movable block 6 at its bottom. During high-frequency vibration, the movable block 6 is connected to the inner walls on both sides of the movable port 10 through the elastic element 11 to maintain a stable position. At the same time, the turbulence ring 12 at the bottom of the sealed container 1 rotates together with the central axis 3. The composite disturbance mechanism inside the turbulence ring 12 operates, and the disturbance plate 13 and the bellows 14 generate complex fluid dynamic effects during rotation. Finally, the vibration energy generated by the ultrasonic transducer unit 7 and the turbulence effect brought by the turbulence ring 12 work together to the liquid medium, so that the diamond powder is uniformly dispersed in the entire sealed container 1, thereby completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
