Quick-Change Dispersing Unit for Modular Pre-Fine Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dispersing units require separate devices for pre-dispersion and fine dispersion, leading to increased production and storage space, high costs, contamination issues, and complex assembly, especially in large-scale production where changing between processes is inefficient and time-consuming.
Innovation Solution
A dispersing unit with a height-adjustable motor head and quick-change means allows for easy detachment and adjustment of the dispersing device, shifting the parting plane to the support element, enabling simple conversion between pre- and fine dispersion without the need for lifting devices or complex coupling systems, reducing downtime and contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate devices are used for pre-dispersion and fine dispersion, then dispersion quality is improved, but production space and storage space increase
Solution Approach 1:
The patent combines pre-dispersion and fine dispersion functions into a single dispersing unit. The dispersing device can be configured with both a dissolver for pre-dispersion and a grinding basket for fine dispersion, allowing both functions to be performed in one machine, thereby reducing production space requirements while maintaining dispersion quality.
Solution Approach 2:
The dispersing unit is designed as a multi-functional device that can perform both pre-dispersion and fine dispersion operations. The single unit can be adapted to different configurations depending on whether pre-dispersion, fine dispersion, or both are required, making it a universal solution that replaces multiple separate devices.
2Manufacturing precision
If separate devices are used for pre-dispersion and fine dispersion, then dispersion quality is improved, but device complexity increases
Solution Approach 1:
The dispersing device is segmented into modular components including the dissolver, grinding basket, and various attachments. These modular segments can be independently assembled, disassembled, and configured based on specific dispersion requirements, reducing overall assembly complexity while maintaining the capability for both pre-dispersion and fine dispersion.
3Adaptability or versatility
If a fine dispersing unit is permanently installed in the production area, then fine dispersion capability is maintained, but contamination risk increases
Solution Approach 1:
The dispersing device allows dynamic configuration where the grinding basket for fine dispersion can be attached when needed and removed when not required. This dynamic adaptability enables the system to maintain fine dispersion capability on demand while reducing contamination risk by minimizing the presence of the fine dispersing unit in the production area during pre-dispersion operations only.
4Measurement precision
If lifting devices are used to position the grinding tool, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The design eliminates the need for complex lifting devices by positioning the parting plane at the support element level, creating an equipotential working position that can be easily accessed and adjusted without requiring sophisticated lifting and positioning mechanisms, thereby reducing coupling system complexity while maintaining adequate positioning accuracy.

AI summary
The invention relates to a dispersion unit comprising a stand for holding a motor head 2 with a motor arranged therein, which drives a shaft 4, a bearing flange 6 for supporting the shaft 4, which is connected to the motor head 2 at an upper end and has a support element at a lower end, and a fine dispersion unit that can be driven via the shaft 4 and is connectable to the support element. To simplify the replacement of the fine dispersion unit for product changes, the invention proposes providing quick-change means for the detachable attachment of the fine dispersion unit to the support element.
