Filter Cloth Nozzle Sequencing for Uniform Filter Press Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter cloth cleaning methods in filter presses result in uneven cleaning due to cleaning liquid collision at the center, leading to incomplete coverage and increased water usage and time.
Innovation Solution
Implementing first and second cleaning nozzles positioned diagonally on either side of the filter cloth to ensure comprehensive cleaning, with simultaneous and sequential jetting techniques to cover the entire surface efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cleaning nozzles are arranged only at upper right and left positions jetting toward center, then number of components is reduced, but cleaning uniformity deteriorates due to liquid collision at center
Solution Approach 1:
The cleaning process is segmented into multiple sequential phases: first cleaning only the right side, then only the left side, and finally simultaneous cleaning of both sides. This temporal segmentation allows each nozzle to cover its designated area without collision, ensuring uniform cleaning while maintaining the simple two-nozzle configuration.
Solution Approach 2:
The cleaning system dynamically switches between different operational modes: single-nozzle cleaning phases followed by dual-nozzle simultaneous cleaning. This dynamic operation allows the system to adapt the cleaning pattern to avoid liquid collision while maintaining component simplicity, resolving the contradiction between device complexity and cleaning uniformity.
2Loss of time
If cleaning liquid is jetted from both sides simultaneously toward center, then cleaning time is reduced, but cleaning uniformity deteriorates due to collision preventing liquid from reaching diagonal portions
Solution Approach 1:
The cleaning operation uses periodic action by alternating between single-nozzle cleaning phases and dual-nozzle simultaneous cleaning phases. This periodic switching ensures that diagonal portions receive adequate liquid coverage during single-nozzle phases while still benefiting from accelerated cleaning during simultaneous phases, balancing cleaning time and uniformity.
Solution Approach 2:
The system dynamically adjusts the cleaning pattern by switching between different operational modes: single-nozzle cleaning for comprehensive coverage and dual-nozzle simultaneous cleaning for time efficiency. This dynamic adaptation resolves the contradiction between cleaning time and cleaning uniformity.
3Area of stationary object
If cleaning nozzles are positioned to jet toward diagonal corners, then whole surface coverage is improved, but liquid scatter to outside increases
Solution Approach 1:
The cleaning system applies local quality by directing cleaning liquid with different characteristics to different areas: single-nozzle jetting provides broader coverage for diagonal portions while dual-nozzle simultaneous jetting provides concentrated cleaning for the center area. This localized approach ensures comprehensive coverage while containing liquid scatter through guide rails.
