Cleaning Element Gasket Seal for Filter Suction Losses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtration devices experience inefficiencies in suctioning solid particles due to excessive losses, and they are not suitable for use with chemically aggressive fluids like seawater.
Innovation Solution
A cleaning element with a cylindrical design featuring a gasket between the connection tube and the cleaning block for a hermetic seal, combined with a rotatable central suction duct and elastic pushing means, allows for improved suction efficiency and compatibility with aggressive fluids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the connection tube is inserted in the receiving cavity in a sliding contact relationship, then the device structure is simple, but excessive losses occur in the suction of solid particles
Solution Approach 1:
A gasket is introduced as an intermediary element between the connection tube and the receiving cavity. This gasket creates a hermetic seal that prevents excessive losses during suction while maintaining the sliding contact relationship for simplicity. The gasket acts as a mediator that resolves the contradiction by enabling both low losses and simple structure.
2Productivity
If a hermetic seal is implemented during suction, then suction efficiency increases, but the device structure becomes more complex
Solution Approach 1:
The gasket serves as a simple intermediary component that provides hermetic sealing without significantly increasing device complexity. It enables high suction efficiency by preventing losses while adding minimal structural complexity through a single sealing element.
3Adaptability or versatility
If the cleaning element is used with chemically aggressive fluids like seawater, then versatility increases, but material durability becomes a concern
Solution Approach 1:
The cleaning element employs composite material construction, combining stainless steel components (connection tube, receiving cavity) that provide chemical resistance with elastomeric gasket material that offers both sealing and corrosion protection. This composite approach enables versatility with aggressive fluids while maintaining material durability through selective material properties.
