Solution Overview
Problem
Existing methods for mixing water-absorbent resin particles with additives, such as silica particles, are not suitable for producing large quantities and require mechanical-stirring type blending machines, which are inefficient for multiple types of particles and additives.
Innovation Solution
A production method involving stepwise mixing using a first mixer for adding an additive to the first particles and a second mixer for the second particles, followed by a gravity blender to combine the mixed particles and additives, allowing for efficient mixing of two or more types of particles with additives in a large quantity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical-stirring type blending machines (ribbon blender or Loedige mixer) are used to mix water-absorbent resin particles with additives, then mixing can be achieved, but the method is not suitable for producing large amounts of particle mixture containing two or more types of water-absorbent resin particles and additives efficiently
Solution Approach 1:
The mixing process is segmented into multiple stages: first mixing each type of water-absorbent resin particles with additives separately in individual mixers, then combining the pre-mixed particles in a blender container. This segmentation allows efficient handling of large quantities while maintaining mixing quality.
Solution Approach 2:
Additives are preliminarily mixed with each type of water-absorbent resin particles before combining different particle types. This preliminary action ensures uniform distribution of additives and simplifies the subsequent mixing process for large-scale production.
2Ease of operation
If mechanical-stirring type blending machines are used for mixing, then mixing function is provided, but the method requires complex mechanical stirring mechanisms that reduce ease of operation for large-scale production
Solution Approach 1:
The blender container utilizes gravity to naturally mix the combined particle mixtures without requiring complex mechanical stirring mechanisms. The particles self-mix through gravitational movement, simplifying the device structure and improving ease of operation while maintaining high productivity.
3Productivity
If all particle types and additives are mixed together in one step using mechanical stirrers, then mixing can be achieved, but the process becomes inefficient and difficult to scale up for large amounts
Solution Approach 1:
The mixing operation is divided into sequential segments where each particle type is pre-mixed with additives separately, then combined in a final blending stage. This reduces total mixing time and enables scalable production.
Solution Approach 2:
Pre-mixing additives with individual particle types before combination accelerates the overall process by ensuring uniform distribution early, reducing the time required for final blending and enabling faster scale-up.
