Motorized Filter Cartridge Cleaning System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning filter cartridges with pleated media are inefficient, prone to damage, and create hazardous environments, as they often delaminate the filter media and result in inconsistent and operator-dependent cleaning processes.
Innovation Solution
A motorized filter cartridge cleaning system that uses a rotating cage and tank with controlled cleaning fluids and agitation to effectively clean pleated filter cartridges without delamination, allowing for repeatable and safe operation, and enabling simultaneous cleaning of multiple cartridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If compressed air or water is used to clean filter cartridges, then cleaning effectiveness is improved, but the filter media becomes delaminated and damaged
Solution Approach 1:
The patent replaces high-pressure mechanical cleaning (compressed air/water) with a low-pressure mechanical scraping system. A rotating cage with scraper blades mechanically removes accumulated material from the filter media surface through gentle contact, eliminating the need for high-pressure forces that cause delamination while maintaining effective cleaning.
2Productivity
If high pressure air or water is used for cleaning, then particle removal is improved, but small particles are forced deep into the filter media
Solution Approach 1:
The patent substitutes high-pressure fluid jets with a mechanical scraping system that uses controlled contact force. The scraper blades on the rotating cage gently scrape the filter media surface, removing particles without forcing them into the media pores, thus maintaining filter effectiveness while achieving thorough cleaning.
3Ease of operation
If manual cleaning methods are used, then operator flexibility is maintained, but cleaning consistency and repeatability deteriorate
Solution Approach 1:
The patent implements an automated self-cleaning system where the rotating cage with scrapers automatically cleans multiple filter cartridges in sequence. The system requires minimal operator intervention (loading cartridges and periodic maintenance) while delivering consistent, repeatable cleaning results through automated mechanical action, eliminating variability associated with manual cleaning.
4Productivity
If compressed air cleaning is performed in an open environment, then cleaning speed is improved, but dust clouds contaminate surroundings and create safety hazards
Solution Approach 1:
The patent replaces compressed air blasting with a mechanical scraping system that contains cleaning activity within a closed cage structure. The scrapers physically remove and contain accumulated material, preventing dust clouds from escaping into the environment, thereby eliminating contamination and explosion hazards while maintaining efficient cleaning.

AI summary
A system for cleaning filter cartridges having a cylindrically configured filter media. The cleaning system includes a tank for containing a cleaning liquid, and an open-sided cage for removably receiving and containing one of the filter cartridges to be cleaned. The cage is supported on a drive shaft of a motorized drive that is positionable for disposing the open-sided cage and filter cartridge contained therein in cleaning liquid in the tank and is selectively operable for rotating the open-sided cage and filter cartridge contained therein during a cleaning cycle for cleaning the filter media of the contained filter cartridge.
