Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ultrafiltration devices lack effective flushing functions, leading to uneven cleaning and a shortened service life of filter elements, necessitating frequent replacements and increased costs.
Innovation Solution
A filter device with a spirally flushing function, featuring a head with water inlet, outlet, and flushing holes, a filter flask main body, filter element, casing, flow divider, and end cap, where raw water enters through a spiral passage, flows over the filter element, and concentrated water is flushed out, ensuring full and even spiraling flow for enhanced cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If traditional ultrafiltration devices are used without a flushing function, then the device structure is simple, but the filter element service life is short and flushing effect is poor
Solution Approach 1:
The device is divided into distinct functional components: filtration chamber, flushing chamber, flow divider, and multiple passage systems. The flow divider segments the water flow into different paths (filtration passage, flushing passage, concentrated water passage), allowing independent optimization of each function while maintaining overall system integrity.
Solution Approach 2:
The water inlet passage serves dual purposes: it supplies water for both filtration and flushing operations. The concentrated water passage simultaneously collects waste water and provides flushing water to the filter element, eliminating the need for separate flushing water supply systems.
2Reliability
If traditional ultrafiltration devices have a flushing function, then the device structure is improved, but the flushing is uneven and dead angles remain
Solution Approach 1:
The flow divider is designed with a curved water guiding surface that directs water flow in an arc-shaped path along the filter element. This curved geometry ensures uniform water distribution across the entire filter element surface, eliminating dead angles and ensuring complete coverage during flushing operations.
Solution Approach 2:
The device implements different flow characteristics in different regions: the water inlet passage provides high-pressure flow for filtration, while the concentrated water passage provides low-pressure flow for flushing. The flow divider creates localized flow patterns that adapt to the specific requirements of each region of the filter element.
3Ease of manufacture
If frequent filter element replacement is required, then the flushing function is insufficient, but the operational cost increases
Solution Approach 1:
The system uses its own concentrated water output as the flushing water source, eliminating the need for external flushing water supply. The filtered water that would otherwise be discarded is redirected to clean the filter element, creating a self-sustaining flushing system that reduces operational costs and water consumption.
Solution Approach 2:
The system recovers the concentrated water that exits the filter element during filtration and redirects it to the flushing passage. This recovered water, which contains some pressure and volume, is reused for cleaning the filter element, preventing waste and reducing the need for additional water resources.
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
The spirally flushing mechanism effectively prolongs the service life of the filter element by ensuring a better flushing effect, reducing the need for frequent replacements and lowering operational costs.
Implementation Method 1
concentrated water enters the flushing passage from the lower end of the filter element, and spirally flows out from the flushing hole
Implementation Method 2
raw water enters the filter element casing through the plurality of filter element casing water inlets in a spiral manner, and then the raw water flows in a rotating manner on the surface of the filter element
