Filter Cleaning via Intermediate Structure Energy Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collector cleaning systems face inefficiencies due to non-optimal distribution of shock waves, mechanical stress concentration, and lack of flexibility in cleaning timing, leading to reduced effectiveness and increased energy consumption, as well as potential breakages and uneven air flow paths.
Innovation Solution
A cleaning system with an intermediate structure that absorbs energy differently between its inner and outer regions, distributing kinetic energy to filter materials for effective dust removal and preventing re-adhesion, while allowing flexible operation timing and improved air flow paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional cleaning system applies shock waves directly to the filtering device, then dust removal effectiveness is improved, but mechanical stress concentration causes breakages and uneven air flow paths
Solution Approach 1:
The patent introduces an intermediate structure positioned between the shock wave source and the filtering device. This intermediate structure absorbs and redistributes the shock waves, preventing direct concentration of mechanical stress on the filtering device while still enabling effective dust removal. The intermediate structure acts as a mediator that transforms the direct shock wave impact into a more distributed cleaning action.
2Productivity
If shock waves are applied strongly to remove dust, then cleaning effectiveness is improved, but energy consumption increases
Solution Approach 1:
The patent modifies the parameters of shock wave propagation by introducing the intermediate structure, which changes how energy is distributed. Instead of applying high-intensity shock waves directly to the filtering device (high energy consumption), the intermediate structure enables effective dust removal with modified shock wave parameters, reducing the overall energy required while maintaining cleaning effectiveness.
3Reliability
If the cleaning system operates frequently to maintain filtration efficiency, then filtration performance is maintained, but energy consumption and mechanical wear increase
Solution Approach 1:
The intermediate structure enables more efficient cleaning operations by distributing shock waves uniformly. This allows the cleaning system to operate less frequently while still maintaining filtration efficiency, as each cleaning cycle is more effective and causes less mechanical wear, thereby reducing both energy consumption and wear over time.

AI summary
An apparatus comprises a filtering device (2) which includes a plurality of filtering elements (3) made of a filter material. The apparatus further comprises a cleaning system (1) for periodically cleaning the filtering device (2) in order to remove contaminating particles from the filtering device (2). The cleaning system (1) has at least one percussion element (6) for applying percussions at least on an impact surface (10) of an intermediate structure (100), so as to generate, for each percussion, an impact which is able to detach from the filter material a first fraction of the contaminating particles adhering to the filter material and then vibrate the filter material to detach from it further contaminants. The intermediate structure (100), which is interposed between the percussion element (6) and the filter material, has an inner region (50) delimited at least partly by the impact surface (10) and an outer region (60) which surrounds at least partly the inner region (50). The intermediate structure (100) has a capacity to absorb the energy deriving from the percussion which is greater in the inner region (50) than the outer region (60).
