Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of basket grinders, and specifically to a counterweight-damped basket grinder. Background Technology
[0002] A basket mill is a widely used grinding and dispersing equipment in industries such as chemical, coating, ink, food, and pharmaceutical. It is primarily used to grind solid particulate materials into fine powder and uniformly disperse them in a liquid medium. The structure of a basket mill typically includes: a motor, a grinding basket, a stirring shaft, a dispersing disc, a feed inlet, and a discharge outlet. Its working principle is as follows: When the basket mill is working, the motor drives the stirring shaft to rotate at high speed via a coupling. The impeller on the stirring shaft pushes the grinding media and material in the grinding basket in a circular motion, generating strong stirring and shearing forces. Under this force, the particles in the material are continuously impacted, squeezed, and rubbed by the grinding media, thus being broken and ground into fine powder. Simultaneously, the rotation of the dispersing disc causes the ground material to flow out of the grinding basket, where it is further dispersed and mixed under the action of the dispersing disc, and finally discharged from the discharge outlet.
[0003] Key rotating components of basket mills, such as the stirring shaft and grinding basket, are prone to wear during long-term high-intensity operation. For example, the grinding basket is inevitably worn due to its continuous interaction with the material and grinding media. Once worn, it will cause uneven mass distribution, resulting in centrifugal force imbalance and vibration. This will not only affect the stability of equipment operation, but also cause components to loosen and be damaged due to vibration, increasing the frequency and cost of maintenance.
[0004] Meanwhile, the distribution and flow of materials in the grinding basket have a significant impact on the stability of equipment operation. Differences in material characteristics and unreasonable feeding methods can easily cause uneven material accumulation, forming eccentric forces, which can lead to equipment shaking and vibration. In severe cases, this can affect the grinding effect and reduce the consistency of product quality. Utility Model Content

[0022] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.
[0023] like Figures 1 to 4 As shown, a counterweight-damped basket grinder includes a base 1, a grinding cylinder 2, a hydraulic cylinder 3, a movable top plate 4, a grinding assembly 5, and a counterweight 6. The grinding cylinder 2 and the hydraulic cylinder 3 are both located on the top of the base 1. The movable top plate 4 is fixedly connected to the telescopic end of the hydraulic cylinder 3. The grinding assembly 5 is fixedly connected to the movable top plate 4. The counterweight 6 is slidably connected to the top of the movable top plate 4. The movable top plate 4 is provided with an adjustment assembly 7 for adjusting the position of the counterweight 6 on the movable top plate 4.
[0024] During equipment operation, when rotating parts wear down due to prolonged high-intensity operation, resulting in uneven mass distribution and centrifugal force imbalance, or when uneven material accumulation within the grinding basket 15 due to differences in material properties or improper feeding methods, causing eccentric force, the equipment will vibrate. In such cases, the position of the counterweight 6 can be adjusted using the adjusting component 7 on the movable top plate 4. By changing the position of the counterweight 6, the equipment's center of gravity can be balanced, effectively counteracting the unbalanced force caused by component wear or material distribution issues, thus achieving a vibration reduction effect.
[0025] By adjusting the counterweight 6, the eccentric force caused by wear of the grinding basket 15 or uneven material distribution can be effectively counteracted, reducing equipment vibration and improving operational stability. Reduced vibration lowers the risk of loosening and damage to equipment components, thus extending the equipment's service life. The adjustment function of the counterweight 6 also reduces wear on key rotating components such as the grinding basket 15, further extending their service life. Stable equipment operation ensures the uniformity of the grinding process, improving product quality consistency. Reduced vibration also avoids problems such as material stratification or uneven mixing caused by vibration, further improving product quality.
[0026] In some specific embodiments, the adjusting assembly 7 includes a movable slide 8, which is slidably connected to the movable top plate 4, and a counterweight 6 is fixedly mounted on the top of the movable slide 8. The adjusting assembly 7 also includes a guide slide rod 9 and an adjusting screw 11. The guide slide rod 9 is horizontally fixedly connected to the movable top plate 4, and the movable slide 8 has a guide hole 10 that mates with the guide slide rod 9. The adjusting screw 11 is horizontally rotatably connected to the movable top plate 4, and the movable slide 8 has an adjusting screw hole 12 that mates with the adjusting screw 11.
[0027] When the adjusting screw 11 rotates, the adjusting screw hole 12 of the movable slide 8 engages with the adjusting screw 11, and the guide slide 9 restricts the movable slide 8 to move only in its direction. Therefore, the movable slide 8 will move linearly along the guide slide 9, thereby precisely changing the position of the counterweight 6. The guide slide 9 ensures the linearity and stability of the movement of the movable slide 8, and the adjusting screw 11 provides a precise fine-tuning method, making the position adjustment of the counterweight 6 more accurate and better adaptable to different imbalance states of the equipment.
[0028] In some specific implementations, the adjustment assembly 7 also includes an adjustment handwheel 13, which is rotatably connected to the movable top plate 4 and coaxially fixedly connected to the adjustment screw 11. The operator manually rotates the adjustment handwheel 13, causing the adjustment screw 11 to rotate synchronously, thereby adjusting the position of the movable slide 8 and the counterweight 6. The operation is intuitive and convenient, allowing operators to manually adjust the position of the counterweight 6 at any time according to the equipment's operating conditions, which is advantageous in scenarios where timely response to changes in equipment operating status is crucial.
[0029] In some specific implementations, the adjustment assembly 7 also includes an adjustment motor, which is fixedly connected to the movable top plate 4, and the output end of the adjustment motor is coaxially fixedly connected to the adjustment screw 11. After the adjustment motor is started, its output end drives the adjustment screw 11 to rotate, thereby realizing the automatic adjustment of the position of the movable slide 8 and the counterweight 6. This enables automated control and is suitable for working conditions requiring frequent and rapid adjustments to the position of the counterweight 6, improving adjustment efficiency, reducing manual operation intensity, and facilitating integration with the equipment's automated control system for overall automated operation.
[0030] In some specific embodiments, the grinding assembly 5 includes a grinding motor 14, a grinding basket 15, a drive shaft 16, a dispersing disc 17, and impellers. Both the grinding motor 14 and the grinding basket 15 are fixedly connected to the movable top plate 4. One end of the drive shaft 16 is coaxially and fixedly connected to the output end of the grinding motor 14, and the other end of the drive shaft 16 passes through the grinding basket 15. The dispersing disc 17 is coaxially and fixedly connected to the other end of the drive shaft 16, and the impellers are fixedly disposed on the side of the other end of the drive shaft 16. After the grinding motor 14 is started, it drives the dispersing disc 17 and the impellers to rotate at high speed via the drive shaft 16, thereby shearing, stirring, and grinding the material within the grinding basket 15.
[0031] In some specific embodiments, an elastic element 18 is provided on the top of the base 1, and a support plate is fixedly provided on the top of the elastic element 18. The grinding cylinder 2 is detachably installed on the top of the support plate. Symmetrically distributed movable clamping blocks 19 are provided at both ends of the top of the support plate, and a limiting bracket 20 is provided on the support plate that is slidably connected to the movable clamping blocks 19. The elastic element 18 includes several springs arranged in a matrix on the top of the base 1.
[0032] The vibrations generated during equipment operation are transmitted to the elastic element 18 through the bearing plate. The spring undergoes elastic deformation, absorbing the vibration energy and reducing the transmission of vibration to the base 1. The movable clamping block 19 and the limiting bracket 20 are used for convenient installation and fixation of the grinding cylinder 2. The elastic element 18 further enhances the vibration damping performance of the equipment, and the matrix arrangement of multiple springs can more evenly absorb vibrations from all directions. The movable clamping block 19 and the limiting bracket 20 facilitate the installation, disassembly, and replacement of the grinding cylinder 2, improving the convenience of equipment maintenance.
[0033] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
