Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning bag type filters are inefficient and lack a standardized, effective device for delivering fluid flow to clean the interior surfaces effectively.
Innovation Solution
A device comprising a frame or cage configured for insertion into the bag filter, with a rotating nozzle assembly delivering fluid flow, and a mounting member for attachment to a cleaning apparatus, ensuring effective cleaning by separating the nozzle from the filter surface and allowing easy attachment to existing cleaning apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hose is inserted into the filter for cleaning, then the cleaning process is simple, but the cleaning efficacy is insufficient and lacks standardization
Solution Approach 1:
The cleaning device is segmented into distinct functional components: a frame structure, a rotating nozzle assembly, and a mounting member. This segmentation allows each component to perform its specific function effectively while maintaining overall system simplicity for easy manufacturing and deployment.
Solution Approach 2:
The frame acts as an intermediary structure that positions the nozzle assembly at the optimal location within the filter. This intermediary framework enables standardized fluid delivery without requiring direct insertion of hoses, thereby improving cleaning efficacy while maintaining ease of manufacture.
2Quantity of substance
If the nozzle is placed directly against the filter surface, then fluid flow is maximized, but the filter surface may be damaged
Solution Approach 1:
The frame structure provides localized support and positioning, creating an optimal distance between the nozzle and filter surface. This local structural quality ensures that fluid flow is maximized at the cleaning point while preventing direct contact that could cause damage to the filter media.
Solution Approach 2:
The frame serves as an intermediary between the nozzle and the filter surface, maintaining an optimal spacing that allows effective fluid delivery while preventing mechanical damage. This intermediary structure resolves the contradiction between maximizing fluid flow and protecting the filter surface.
3Reliability
If a standardized cleaning device is implemented, then cleaning efficacy is improved, but device complexity increases
Solution Approach 1:
The mounting member is designed with universal attachment capabilities that can interface with various existing cleaning apparatuses. This universality allows the standardized cleaning device to be integrated into different systems without requiring complex custom interfaces, thereby improving cleaning efficacy while limiting the increase in device complexity.
Solution Approach 2:
The device is segmented into modular components (frame, nozzle assembly, mounting member) that can be manufactured independently and assembled. This segmentation standardizes the cleaning function while keeping each component relatively simple, balancing improved cleaning efficacy with controlled device complexity.
4Object-affected harmful factors
If the frame separates the nozzle from the filter surface, then damage is prevented, but fluid flow delivery efficiency is reduced
Solution Approach 1:
The rotating nozzle assembly introduces dynamic motion to the fluid delivery system. This rotation compensates for the distance created by the frame separation, ensuring that fluid flow is effectively distributed across the filter surface while maintaining protective spacing. The dynamic element maintains delivery efficiency despite the static separation distance.

AI summary
A device configured for cleaning bag filters with compressed air comprises a frame having a hollow interior defining a wall of the frame and openings formed through a thickness of the wall so that the hollow interior is in open communication with an environment external to the frame. A mounting member is configured to be releaseably or permanently attached to one end of the frame and is further configured to be releaseably or permanently attached to a member configured to pass air flow therethrough.
