Filter for the interception of solid compounds circulating in a heating system, and heat generator with filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mesh filters in heating systems require laborious maintenance due to accumulation of solid compounds, necessitating system emptying and refilling, which is costly and time-consuming.
Innovation Solution
A mesh filter positioned in a heat generator's bifurcation, allowing cleaning by switching to a different operating mode, where the heat transfer fluid cleans the filter by carrying away accumulated solids without system emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mesh filter is used to intercept solid compounds, then components are protected from solid compound accumulation, but the filter requires laborious maintenance involving system emptying and refilling
Solution Approach 1:
The filter is segmented into a modular design with a detachable filter element that can be removed and cleaned independently from the heating system. This allows the filter to be maintained without emptying the entire system, resolving the contradiction between protecting components and ease of maintenance.
Solution Approach 2:
A cleaning device is introduced as an intermediary tool that can be inserted through a dedicated access point to clean the filter element without system emptying. This mediator enables easy maintenance while preserving the protective function of the filter.
2Reliability
If the filter is cleaned by emptying and refilling the system, then solid compound accumulation is removed, but time and cost increase
Solution Approach 1:
The filter element is extracted as a separate removable component from the heating system. This extraction allows the filter to be cleaned quickly by simply removing and rinsing the element, eliminating the time-consuming process of emptying and refilling the entire system while maintaining filter functionality.
Solution Approach 2:
The filter element is designed with features that facilitate preliminary preparation for cleaning, such as easy removal mechanisms and cleaning access points. This preliminary design enables rapid maintenance without system emptying, reducing maintenance time while ensuring filter functionality.
3Ease of operation
If the filter is made inspectable and reachable for cleaning, then maintenance can be performed, but system complexity increases
Solution Approach 1:
The filter assembly is segmented into easily accessible modular components with a dedicated cleaning access point. This segmentation provides filter accessibility for maintenance without requiring complex system modifications, balancing ease of operation with system simplicity.
