Filter Device Supply Pipe Routing Through Recess Pack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices face issues with torsional moments and leakage due to flexible supply pipes, which are hazardous for filtering suspensions, and suffer from misalignment and pressure loads causing deflection of components during filtration.
Innovation Solution
A filter device design where the suspension and supply pipes are positioned on opposite sides of the recess plates, with equal sectional areas and integrated ducts, eliminating the need for external flexible pipes and balancing pressure loads, and incorporating vertically stacked or side-by-side recess plates secured by hydraulic or mechanical means with integrated filter cloths and membranes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible supply pipe is used to allow movement of the end piece, then the end piece can move during operation, but the pipe needs to be stiff enough for high-pressure suspension piping which causes a torsional moment when moving the end piece
Solution Approach 1:
The patent inverts the conventional approach by routing the supply pipe through the pack of recess plates instead of running it externally. This internal routing allows the pipe to move with the end piece without being subjected to external bending moments, as the pipe is protected and guided by the pack structure itself.
Solution Approach 2:
The supply pipe is nested within the pack structure, running through the recess plates and filter chambers. This nesting protects the pipe from external forces and allows it to move with the end piece without generating torsional moments, as the pipe is integrated into the moving assembly rather than being an external flexible connection.
2Ease of operation
If a flexible supply pipe is used to allow movement of the end piece, then the end piece can move during operation, but the risk of leakage increases
Solution Approach 1:
Instead of using an external flexible pipe that is prone to leakage, the patent routes the supply pipe internally through the pack structure. This internal routing eliminates the flexible external connection and its associated leakage risks, while still allowing end piece movement through the integrated design.
Solution Approach 2:
The supply pipe is nested within the pack structure, running through the recess plates and filter chambers. This nesting protects the pipe from external damage and leakage risks, as the pipe is integrated into the moving assembly and protected by the pack structure throughout its length.
3Ease of manufacture
If the suspension pipe runs through the pack outside the filter chamber, then the pipe can be positioned for suspension supply, but excentric pressure load of up to several tons causes misalignment and deflection of the end piece and recess plates
Solution Approach 1:
The patent positions the supply pipe asymmetrically through the pack structure, routing it through specific recess plates in a way that balances the pressure loads. The pipe enters through one side of the pack and is positioned to distribute forces more evenly across the end piece and recess plates, reducing misalignment and deflection.
Solution Approach 2:
Instead of running the suspension pipe externally where it creates excentric loads, the patent inverts the approach by routing the pipe internally through the pack structure. This internal routing integrates the pipe with the filter chambers and allows for better load distribution, reducing misalignment and deflection of components.
