Solid-liquid separator with mid-layer supply port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid-liquid separators with layered filter bodies are inefficient as they limit solid-liquid separation processing to a specific portion of the device, resulting in reduced throughput and increased risk of clogging due to incomplete utilization of the separator's length.
Innovation Solution
Incorporating a tubular first pipe member with a sub object-to-be-processed supply port in the middle of the layered filter body, flanges for easy attachment, and an auxiliary pipe member for flocculant or washing water, allowing additional object supply and processing throughout the separator, enhancing throughput and preventing clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conventional single supply port configuration is used, then the device structure is simple, but the throughput is limited and the separator length is not fully utilized
Solution Approach 1:
The patent divides the object-to-be-processed supply into multiple segments by providing both a main supply port at the upstream end and a sub supply port at the middle position of the layered filter body. This segmentation allows different portions of the separator to be utilized independently, increasing overall throughput without requiring complete structural redesign.
Solution Approach 2:
The patent transitions from a single-point supply (one-dimensional) to multi-point supply (adding spatial distribution dimension) by positioning supply ports at different locations along the separator length. This dimensional change in supply configuration enables more effective utilization of the separator's length capacity.
2Productivity
If the separator length is fully utilized for separation processing, then the throughput increases, but the risk of clogging increases due to decreased fluidity
Solution Approach 1:
The sub supply port introduces fresh object-to-be-processed material into the middle position before the material reaches the downstream end. This preliminary action replenishes fluidity upstream, preventing clogging before it occurs while allowing the full separator length to be utilized for separation.
Solution Approach 2:
By continuously supplying material through both the main and sub supply ports, the system maintains continuous fluid motion throughout the separator length. This continuous action prevents stagnation and clogging while maximizing the utilization of the separator for solid-liquid separation.
