Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing granulator devices face challenges in efficiently cleaning filters clogged with significant impurities, as the existing methods are complex, expensive, and difficult to operate, and struggle to effectively remove large quantities of impurities from filter surfaces.
Innovation Solution
A granulator device with rotating cleaning elements and diffuser nozzles that temporarily open the filter to allow washing liquid and impurities to flow out, ensuring thorough cleaning and maximum filtering efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compressed air is blown through the filter wall to remove dust, then dust removal is achieved, but the device becomes complex and expensive
Solution Approach 1:
The invention extracts the cleaning function from the main filter structure by introducing a separate, rotatable cleaning arm with its own nozzle system. This modular approach allows the filter to maintain its primary function while the cleaning arm provides maintenance capability, reducing overall system complexity compared to integrated solutions.
Solution Approach 2:
The cleaning system is designed to be self-servicing through automated rotation and activation. The cleaning arm rotates automatically to cover the entire filter surface, and the system can be activated during maintenance operations without requiring complex manual intervention or multiple separate systems.
2Reliability
If a rotating arm with diffuser nozzles is used to clean filters, then cleaning effectiveness improves, but the device becomes more complex
Solution Approach 1:
The rotating cleaning arm serves multiple functions: it supports diffuser nozzles for washing liquid application, provides mechanical rotation to cover the entire filter surface, and can be activated during maintenance operations. This multi-functionality reduces the need for separate cleaning mechanisms and simplifies the overall device architecture.
3Reliability
If washing liquid is diffused on the filter surface, then impurities are removed, but large quantities of impurities cannot be effectively eliminated
Solution Approach 1:
The invention extracts trapped impurities from the filter wall by temporarily opening a portion of the filter. This creates a direct pathway for washing liquid to reach and flush out impurities that have penetrated into the filter structure, effectively removing large quantities of impurities that surface washing alone cannot eliminate.
Solution Approach 2:
The temporary opening acts as an intermediary mechanism that facilitates the removal of impurities. By creating this temporary pathway, the system enables washing liquid to access and extract impurities from within the filter wall, then allows these impurities to be discharged externally, effectively handling large quantities of removed material.
4Reliability
If the filter is temporarily opened to allow washing liquid flow out, then thorough cleaning is achieved, but the filtering function is interrupted
Solution Approach 1:
The filter opening is implemented as a periodic, temporary action during maintenance operations rather than a continuous state. The filter is opened only when needed for cleaning, allowing thorough removal of impurities, then closed to restore filtering function. This periodic approach minimizes interruption time while achieving complete cleaning when required.
