Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emulsifying apparatuses face challenges in increasing processing capacity without compromising performance and experiencing raw material leakage when scaling up nozzle structures, such as increasing the number of slit chambers or nozzle size, which often results in inefficiencies and increased size.
Innovation Solution
The proposed solution involves a slit chamber and atomizing apparatus configuration that includes a water guide nozzle, an upstream nozzle, an intermediate nozzle with an atomizing channel, and a downstream nozzle, which applies shear stress and collision forces to the raw material through a series of channels to efficiently atomize and process a large volume of raw material while minimizing leakage, using a compact design with high-hardness materials and optimized channel geometries.

Engineering Contradiction Analysis
1Productivity
If the number of slit chambers or nozzle size is increased to improve processing capacity, then the processing amount per hour increases, but the apparatus size increases and space requirements increase
Solution Approach 1:
The slit chamber is divided into multiple nozzles (first nozzle, second nozzle, third nozzle, fourth nozzle) arranged in series along the flow direction. Each nozzle processes a portion of the raw material, enabling increased processing capacity without requiring parallel chambers that would increase overall apparatus volume. The segmented nozzle structure allows compact arrangement while maintaining high productivity.
Solution Approach 2:
Instead of increasing processing capacity by adding more nozzles in parallel (planar arrangement), the invention arranges nozzles in series along the flow direction (adding dimensionality). This vertical/longitudinal arrangement allows multiple processing stages within a compact footprint, increasing productivity without proportionally increasing apparatus volume.
2Productivity
If the number of nozzles is increased to improve processing capacity, then the processing amount increases, but gaps between nozzles increase causing raw material leakage
Solution Approach 1:
The invention combines multiple nozzles into a single integrated slit chamber structure where nozzles are closely arranged without significant gaps. The nozzles share common walls and are positioned adjacently, merging their functions while eliminating leakage paths. This unified structure maintains reliability by preventing raw material leakage between nozzles even as processing capacity increases.
Solution Approach 2:
The nozzles are arranged in a nested-like configuration where subsequent nozzles are positioned downstream of previous ones, with each nozzle processing the flow sequentially. This nested arrangement maximizes space utilization and ensures complete coverage of the raw material stream, preventing leakage while maintaining high processing capacity.
3Productivity
If the nozzle size is increased to process larger amounts of raw material, then the processing capacity increases, but the effect is reduced due to deteriorated processing performance
Solution Approach 1:
The processing function is segmented across multiple nozzles rather than relying on a single large nozzle. Each nozzle maintains optimized dimensions for effective atomization and processing performance, while the collective arrangement of nozzles handles large volumes. This segmentation preserves manufacturing precision and processing performance even when handling large amounts of raw material.
Solution Approach 2:
Each nozzle is designed with local optimizations for its specific processing function, with channel dimensions and geometries tailored to maintain high processing performance. Rather than uniformly scaling up all dimensions, the local quality of each nozzle section is optimized independently, ensuring consistent performance across the entire system while processing large volumes.
