Self-Cleaning Filter With Elastic Suction Nozzles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior self-cleaning filters with rigid support rods for suction pads are inefficient in handling irregular filter surfaces and large impurities, and elastic spacers that allow axial movement are unsatisfactory for non-circular profiles and large dirt particles.
Innovation Solution
The self-cleaning filter features radially arranged suction nozzles with elastic connecting ducts that allow for rotation and flexibility, enabling the suction pads to conform to irregular surfaces and effectively remove impurities, with a T-shaped suction pad design and expansion tank for enhanced suction power and a quick-connect mechanism for easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid support rods are used to fix suction pads, then structural stability is improved, but adaptability to irregular surfaces deteriorates
Solution Approach 1:
The suction pad is designed with a flexible body that can deform and conform to irregular surfaces of the filter element. This flexibility allows the suction pad to adapt to non-circular profiles and surface irregularities while maintaining stable attachment through the rigid support rod connection to the suction nozzle.
2Adaptability or versatility
If elastic spacers are used to allow axial movement, then adaptability to surface irregularities is improved, but effectiveness against large dirt particles deteriorates
Solution Approach 1:
The suction nozzle is designed to rotate about the filter element axis, creating a dynamic cleaning mechanism. This rotation allows the suction nozzles to effectively remove large dirt particles through centrifugal force and continuous motion, while the flexible suction pads maintain adaptability to surface irregularities during the rotation.
3Ease of operation
If suction pads are fixed to rotating central suction duct, then ease of operation is improved, but cleaning effectiveness on irregular surfaces deteriorates
Solution Approach 1:
The suction system is segmented into multiple independent suction nozzles distributed around the filter element, each with its own flexible suction pad. This segmentation allows each nozzle to independently adapt to local surface irregularities while maintaining ease of operation through centralized rotation about the filter element axis.
