Description

Technical Field

[0002] In the early-stage pilot-scale experiments and small-batch production of liquid slurries such as paints, coatings, pigments, plastics, and food products, the precision control and ease of operation of dispersion equipment directly affect the reliability of experimental data and production efficiency. Existing pilot-scale dispersion equipment generally suffers from complex structures and insufficient adjustment flexibility: traditional equipment often uses rigid lifting mechanisms with fixed motor positions that are difficult to fine-tune quickly, resulting in poor compatibility with different container sizes; some equipment relies on hydraulic or pneumatic systems for lifting, which is not only costly but also complex to maintain; furthermore, during experiments, frequent adjustments to the dispersing impeller immersion depth are required due to changes in material viscosity, but existing equipment lacks convenient positioning and locking functions, easily leading to parameter deviations. Simultaneously, pilot-scale equipment needs to balance the accuracy of experimental data with the practicality of small-batch production, but traditional equipment often focuses on a single function, failing to effectively balance these two needs. Therefore, existing technologies still require improvement and enhancement. Utility Model Content

[0020] Please see Figure 1 and Figure 2This utility model provides a simple high-speed experimental disperser, including a base 1 and a support square tube 2 vertically fixed on the base 1, and further including: a transmission bracket 3 fixed to the top of the support square tube 2; a sprocket 4 rotatably mounted on the transmission bracket 3; a chain 5 wound around the sprocket 4, with its first end connected to a motor mounting plate 6 and its second end connected to a counterweight 7 located inside the support square tube 2; a guide shaft 8 vertically fixed to the side wall of the support square tube 2; and a locking screw 9 threadedly connected to the motor mounting plate 6; wherein the motor mounting plate 6 is slidably sleeved on the guide shaft 8, and the position is locked by tightening the locking screw 9 to abut against the guide shaft 8.

[0021] The balanced design of sprocket 4, chain 5 and built-in counterweight 7 enables lightweight lifting operation of motor mounting plate 6; the combination of guide shaft 8 and locking screw 9 ensures vertical stability of lifting trajectory and provides rigid mechanical locking during high-speed dispersion, effectively suppressing vibration displacement and ensuring uniform dispersion of slurry; the counterweight 7 is integrated inside the support square tube 2, significantly optimizing equipment space layout and adapting to compact laboratory environments.

[0022] In detail, the motor mounting plate 6 includes a horizontally arranged mounting plate 10 and a guide sleeve 11 fixed to its side wall. The guide sleeve 11 is slidably fitted onto the guide shaft 8. A drive motor is mounted on the mounting plate 10. The motor mounting plate 6 adopts a combination design of the horizontal mounting plate 10 and the guide sleeve 11. Through the sliding cooperation between the guide sleeve 11 and the guide shaft 8, it ensures that the motor maintains a strictly vertical state during lifting and lowering, reducing the risk of swaying and off-center loading. The mounting plate 10 provides stable support for the drive motor, optimizes the motor's heat dissipation conditions and maintenance convenience, while the wear-resistant material design of the guide sleeve 11 extends the service life of the guide mechanism.

[0023] In this embodiment, a dispersion assembly is also included, comprising a dispersion shaft and a dispersion disk fixed to the bottom end of the dispersion shaft; the top end of the dispersion shaft is connected to the output shaft of a drive motor. The dispersion assembly achieves efficient power transmission and reduces energy loss through the direct connection between the dispersion shaft and the output shaft of the drive motor. The modular design of the dispersion disk allows for the replacement of different specifications according to material characteristics, improving the equipment's adaptability to various experimental conditions; the rigid connection between the dispersion shaft and the motor ensures dynamic stability under high-speed rotation, avoiding vibration or noise caused by transmission gaps. The dispersion assembly also includes a bearing housing 12 and a bearing 13; the bearing housing 12 is fixed to the mounting plate 10, and the bearing 13 is embedded in the bearing housing 12; the dispersion shaft passes through the bearing 13 and is rotatably supported. The embedded design of the bearing housing 12 and the bearing 13 provides high-precision rotational support for the dispersion shaft, significantly reducing frictional resistance and wear, and extending the equipment's service life. The fixed structure of the bearing housing 12 enhances the dispersion shaft's resistance to radial loads, ensuring dynamic stability during high-speed operation, while also facilitating disassembly and maintenance, reducing maintenance costs. A frequency converter 14 is fixed to the outer wall of the supporting square tube 2, and the frequency converter 14 is electrically connected to the drive motor. The electrical connection between the frequency converter 14 and the drive motor enables stepless speed regulation, which can accurately match the requirements of different material viscosities and process parameters. Frequency conversion control simplifies the operation process, avoids the cumbersome steps of traditional mechanical speed regulation, and at the same time achieves soft start and stable operation by adjusting the power supply frequency, reducing the impact on the power grid and mechanical wear of the equipment.

[0024] The serrated circular dispersion disc of the disperser completes the solid-liquid dispersion, wetting, deagglomeration, and stabilization processes at high speed within the container. This causes the slurry to form a rolling annular flow, generating strong vortices. Particles on the slurry surface spiral down to the bottom of the vortex. A turbulent zone forms 2.5-5 mm from the edge of the dispersion disc, where the slurry and particles are subjected to strong shearing and impact. Outside this zone, two streams are formed, ensuring thorough circulation and agitation of the slurry. Below the dispersion disc, a laminar flow occurs, with slurry layers of different velocities diffusing into each other, thus achieving a dispersion effect.

[0025] In this embodiment, clamping assemblies symmetrically arranged on both sides of the dispersion disk are also included, and the clamping assemblies are mounted on the base 1. The symmetrically arranged clamping assemblies quickly fix the experimental containers through a mechanical structure, replacing traditional manual clamping or external fixing devices, and greatly improving the container replacement efficiency. The symmetrical design of the clamping assemblies ensures that the containers are subjected to uniform force during high-speed dispersion, avoiding the risk of tilting or falling off due to force on one side, and ensuring experimental safety and data consistency. The clamping assemblies include: a support column 15 vertically fixed to the base 1; a clamping rod 16 horizontally passing through the support column 15; and a clamping arm 17 fixed to the end of the clamping rod 16; the clamping arms 17 are symmetrically arranged on both sides of the dispersion disk. The clamping assemblies adopt a linkage structure between the support column 15 and the horizontal clamping rod 16, and the container can be quickly clamped and released by rotating or sliding the clamping rod 16. The operation is simple and the clamping force is adjustable. The symmetrical layout of the clamping arms 17 further optimizes the container fixing stability, and the vertical fixing method of the support column 15 enhances the vibration resistance of the clamping structure, making it suitable for high-frequency experimental scenarios.

[0026] More specifically, the base 1 has an I-beam structure, including two parallel support legs 18 and a connecting portion 19 connecting the two support legs 18; the support column 15 is fixed to the support legs 18. The I-beam base 1 structure, through the combination of the double support legs 18 and the connecting portion 19, significantly improves the overall rigidity and deformation resistance of the equipment, effectively suppressing the transmission of vibrations generated during high-speed operation to the base 1. The support column 15 is directly fixed to the support legs 18, utilizing the mechanical stability of the I-beam structure to enhance the load-bearing capacity of the clamping components, while reducing the impact of uneven foundation settlement on the equipment's accuracy, ensuring long-term reliability.

[0027] In summary, this simple high-speed experimental disperser, through the linkage design of the sprocket 4, chain 5, and built-in counterweight 7, enables the motor mounting plate 6 to achieve gravity balance during lifting, significantly reducing the operational load of height adjustment. The sliding fit between the guide shaft 8 and the motor mounting plate 6 ensures vertical stability of the lifting trajectory. Combined with the mechanical pressure locking mechanism of the locking screw 9, it effectively overcomes the vibration and displacement problems during high-speed dispersion operations, ensuring the consistency of slurry processing. The overall structure fully utilizes the internal space of the supporting square tube 2 to integrate the counterweight, significantly compressing the lateral dimensions of the equipment, making it suitable for confined laboratory spaces. Simultaneously, the simple mechanical structure achieves high-precision locking, significantly reducing manufacturing costs and maintenance complexity. It provides a stable and reliable data foundation for pilot-scale experiments in paints, coatings, and food slurries, and meets the dual requirements of flexibility and durability for small-batch production. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.
