Filtration Membrane Socket With Dual Outlets For Uniform Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing filtration membrane units, the uneven distribution of negative pressure across the ceramic filter leads to varying amounts of filtered water per unit time, resulting in faster clogging in regions closer to the filtrate outlet and reduced maintainability.
Innovation Solution
The filtration membrane unit incorporates a socket with two discharge ports, one on each side of the center in the extending direction, to evenly distribute the suction force and prevent uneven clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the filtrate outlet is disposed at one end in the extending direction of the holder, then the structure is simple, but the negative pressure varies in the lateral direction of the ceramic filter causing uneven filtration and faster clogging in regions closer to the outlet
Solution Approach 1:
The single discharge port is divided into multiple discharge ports (first discharge port and second discharge port) positioned at different locations in the holder. This segmentation allows the suction force to be distributed across multiple points, creating more uniform negative pressure distribution across the ceramic filter and preventing localized clogging while maintaining structural simplicity.
2Device complexity
If the filtrate outlet is disposed at one end in the extending direction of the holder, then the device complexity is low, but the time interval of filter cleaning operation is shortened due to faster clogging
Solution Approach 1:
By segmenting the discharge port into multiple ports distributed across the holder, the filtration load is balanced across different regions of the ceramic filter. This prevents premature clogging in any single region, thereby extending the time interval between cleaning operations without increasing overall device complexity.
Solution Approach 2:
The multiple discharge ports create locally optimized flow distribution patterns. Each discharge port serves a specific region of the ceramic filter, ensuring that negative pressure is relatively uniform across the entire filter surface. This local quality improvement prevents localized clogging and extends the cleaning cycle interval.
3Ease of manufacture
If the filtrate outlet is disposed at one end in the extending direction of the holder, then the manufacturing is simple, but the amount of filtered water per unit time varies in different regions
Solution Approach 1:
The single discharge port is segmented into multiple ports positioned at different locations. This segmentation enables more uniform distribution of the filtered water flow across different regions of the ceramic filter, ensuring consistent productivity throughout the filter surface while maintaining ease of manufacture through simple port positioning.
Solution Approach 2:
Each discharge port is positioned to serve a specific local region of the ceramic filter, creating locally optimized flow patterns. This ensures that the amount of filtered water per unit time is relatively uniform across all regions, improving overall productivity without complicating the manufacturing process.

Function Achieved in This Case
This configuration improves maintainability by ensuring a more uniform filtration rate across the membrane, reducing the frequency of cleaning operations and extending the time between filter cleanings.
Implementation Method 1
When a negative pressure is generated at the filtration outlet by a suction force of a pump or the like, the treatment target water present around the ceramic filter is sucked into the fine pores of the ceramic filter and filtered.
Implementation Method 2
the treatment target water present around the ceramic filter is sucked into the fine pores of the ceramic filter and filtered
Implementation Method 3
the treatment target water present around the ceramic filter is sucked into the fine pores of the ceramic filter and filtered

AI summary
A filtration membrane unit includes a filtration membrane and a suction side socket fixed to an end on one side in a longitudinal direction of the filtration membrane to hold the filtration membrane. The suction side socket extends in a lateral direction of the filtration membrane in a fixed state, and includes a recess into which the end is inserted. A flow path communicated with the recess extends in an extending direction of the suction side socket. A discharge port for discharging filtrate in the flow path is provided. The suction side socket includes a first outlet disposed on one side in the extending direction with respect to a center in the extending direction of the suction side socket, and a second outlet disposed on another side in the extending direction with respect to the center in the extending direction of the suction side socket.
