Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emulsifying apparatuses face challenges in increasing processing capacity without compromising performance and are prone to raw material leakage when scaling up, as adding more nozzles or increasing nozzle size leads to space inefficiencies and potential leakage issues.
Innovation Solution
The proposed slit chamber and atomizing apparatus include a water guide nozzle, upstream nozzle, intermediate nozzle, and downstream nozzle configuration that applies shear stress and impact force to atomize raw materials efficiently, with a multi-nozzle arrangement that minimizes leakage and maintains performance, using a pressure intensifier to manage the flow of raw materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of nozzles is increased to increase processing capacity, then the processing amount per hour is improved, but the gap between nozzles increases causing leakage of raw material
Solution Approach 1:
The nozzle is segmented into multiple stages (water guide nozzle, upstream nozzle, intermediate nozzle, downstream nozzle) with multiple atomizing channels at each stage. This segmentation allows the raw material to be atomized progressively through multiple channels in series, increasing processing capacity while maintaining tight spacing between channels to prevent leakage.
2Productivity
If the size of nozzles is increased to increase processing capacity, then the processing amount per hour is improved, but the nozzle size becomes excessive and space efficiency deteriorates
Solution Approach 1:
Instead of increasing nozzle size in a single dimension, the invention uses multiple atomizing channels arranged in series along the flow direction (longitudinal dimension). Each channel processes a portion of the raw material, and the cumulative effect of multiple channels increases processing capacity without requiring any single nozzle to be excessively large.
3Productivity
If the channel diameter is increased to increase processing capacity, then the processing amount per hour is improved, but the atomizing performance deteriorates
Solution Approach 1:
The atomizing process is segmented into multiple stages, each with its own atomizing channels of optimized diameter. The raw material passes through multiple channels in series, with each channel contributing to the overall atomization. This allows the use of multiple smaller-diameter channels that maintain good atomizing performance while collectively processing larger amounts of raw material.
4Productivity
If multiple chambers are arranged in parallel to increase processing capacity, then the processing amount per hour is improved, but the space requirement increases
Solution Approach 1:
Multiple atomizing channels are merged into a single integrated nozzle structure rather than using separate parallel chambers. The channels are arranged in series within the same nozzle body, allowing the raw material to flow through multiple atomizing paths sequentially. This merging approach increases processing capacity while maintaining a compact single-chamber design that uses space efficiently.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables efficient processing of large raw material amounts while suppressing leakage and maintaining performance in a compact design, ensuring continuous shear stress and collision forces are applied to the raw materials, even at increased flow rates.
Implementation Method 1
Each liquid mixture ejected from the nozzle can pass through two first through holes. The first liner member has a groove portion that allows the end portion of the through hole to communicate with one of the plate surfaces. The second liner member is disposed on the outflow side in close contact with the first liner member. The second liner member has a second groove portion on a surface closely opposed to the first liner member. Two second through holes for discharging are formed at both outer ends of the second groove portion. Emulsification is performed while the mixture passes through the first and second liner members.
Implementation Method 2
a water guide nozzle to which a raw material is introduced; an upstream nozzle disposed downstream of the water guide nozzle, the upstream nozzle including an upstream nozzle water guide for the raw material to pass through; an intermediate nozzle disposed downstream of the upstream nozzle, the intermediate nozzle including an intermediate nozzle atomizing channel to atomize the raw material; and a downstream nozzle disposed downstream of the intermediate nozzle, the downstream nozzle including a downstream nozzle atomizing channel to atomize the raw material that has flown the intermediate nozzle
