Multi-Motor Suction Filter Valves for Automatic In-Use Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sucking apparatuses require manual filter cleaning, which is inefficient and can lead to incomplete cleaning due to operator negligence, and are complex and costly due to air channelling systems and diverter valves, necessitating a solution for automatic and reliable filter cleaning without operational interruption.
Innovation Solution
The apparatus incorporates valve means with calibrated passages and an electronic control unit to automatically clean filters during operation by redirecting a portion of the airflow to non-working filters, ensuring continuous operation and reduced complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual filter cleaning is used, then the apparatus structure remains simple, but cleaning reliability deteriorates due to operator negligence and incomplete cleaning
Solution Approach 1:
The system performs filter cleaning automatically using its own airflow resources. The suction motor generates airflow that is redirected through calibrated passages to clean the filters during operation, eliminating the need for external cleaning equipment or manual intervention while maintaining structural simplicity
Solution Approach 2:
The invention uses pneumatic principles by utilizing the suction motor's generated airflow to clean the filters. Calibrated passages direct a portion of the airflow to the filters, using air pressure and flow to remove deposited material automatically during operation
2Extent of automation
If air channelling systems with pressure switches and deviator valves are used, then filter cleaning automation is achieved, but device complexity and cost increase
Solution Approach 1:
The system uses its own operational resources (suction motor airflow) to perform filter cleaning automatically. The calibrated passages are passively activated by the motor's operation, eliminating the need for external control systems, pressure switches, or deviator valves while achieving complete automation
Solution Approach 2:
The invention extracts and utilizes the airflow already generated by the suction motor for the additional purpose of filter cleaning. By taking a portion of the existing airflow through calibrated passages, the system achieves dual functionality without adding complex air channelling infrastructure
3Extent of automation
If operator-driven air channelling is used, then some automation is achieved, but cleaning completeness deteriorates due to insufficient operator time dedication
Solution Approach 1:
The system performs filter cleaning automatically during operation without requiring operator intervention. The suction motor continuously generates airflow that cleans the filters through calibrated passages, ensuring consistent and complete cleaning regardless of operator availability or diligence
Solution Approach 2:
The filter cleaning occurs continuously during motor operation rather than as an intermittent manual task. The calibrated passages constantly direct airflow to the filters, ensuring uninterrupted and thorough cleaning that maintains optimal filter performance throughout the apparatus operation
4Reliability
If the apparatus is stopped for filter cleaning, then cleaning thoroughness can be improved, but productivity deteriorates due to operational interruption
Solution Approach 1:
The apparatus maintains continuous operation while filters are being cleaned. The suction motor runs throughout the process, and a portion of its generated airflow is directed through calibrated passages to clean the filters in place, eliminating downtime and maintaining uninterrupted productivity
Solution Approach 2:
The filters are cleaned proactively during normal operation before they become completely blocked. The continuous airflow through calibrated passages prevents material accumulation that would stop the apparatus, maintaining both cleaning effectiveness and operational continuity

AI summary
A sucking apparatus (1), in particular for cleaning, comprises at least two sucking motors (10) arranged for generating a flow of air (F) from the outside to the inside of the apparatus (1), at least two filters (17) arranged downstream of the sucking motors (10) for filtering the flow of air, each filter (17) being associated with a respective sucking motor (10), and a plurality of valve elements (23). The valve elements (23) are interposed between, and operationally associated with, each sucking motor (10) and each filter (17), and are movable between a rest position (R) wherein they are received in respective seats (21), and a raised position (S), wherein they are raised from the respective seats (21) when the sucking motor (10) associated therewith is working, to enable the passage of the flow of air (F) prevalently along a first direction (A). The valve elements (23) are provided with a calibrated passage (20) arranged for enabling, when they are in the rest position (R), the passage of at least one portion (F') of the flow of air substantially along a second direction (B), opposite the first direction (A), from the sucking motor (10) to the filter (17) for cleaning the latter.
