Elastomeric Aeration Element Fitting for Liquid Gasification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aeration systems for liquids, particularly those using elongated aeration elements, face challenges in securely connecting these elements to distribution conduits while accommodating movements and fluid flows, leading to excessive force at connection points and potential detachment issues.
Innovation Solution
The system employs elongated aeration elements with a rigid support tube surrounded by an elastic membrane and a fitting with a semi-rigid plastic saddle and hollow bolt, which provides an elastic mounting and secure connection, allowing for the transportation of air or gas and preventing detachment through interlocking mechanisms and sealing features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plate-shaped aeration elements are connected to the distribution conduit via press-fitted elastic deformation, then the connection is simple and secure, but this connection method is not suitable for elongated aeration elements which experience excessive forces at connection locations
Solution Approach 1:
The aeration element is divided into multiple segments (first aeration element and second aeration element) that can be independently connected to the distribution conduit. Each segment has its own connection fitting, allowing the forces to be distributed across multiple connection points rather than concentrated at single points, thereby reducing excessive forces at each connection location while maintaining ease of assembly.
2Strength
If rigid support structures are used for elongated aeration elements, then the structural strength is improved, but the ability to compensate for movements and flows in the liquid is reduced
Solution Approach 1:
An elastic membrane is introduced as a flexible connection element between the rigid support structure and the distribution conduit. This elastic membrane allows the rigid support structure to maintain its strength while the flexible membrane compensates for movements and flows in the liquid, effectively resolving the contradiction between structural strength and adaptability to movements.
3Reliability
If multiple components are used to create a secure connection, then the connection reliability is improved, but the device complexity and number of components increases
Solution Approach 1:
The connection fitting is designed to integrate multiple functions into a single component: it provides mechanical attachment to the distribution conduit, supports the aeration element, and incorporates the elastic membrane for movement compensation. This merging of functions reduces the total number of separate components while maintaining connection reliability and adaptability.

Implementation Method 1
an elastic mounting and secure connection
Implementation Method 2
compressed air or gas can be introduced between the support tube with a membrane of rubber or a rubber-like polymeric material that is disposed on the support tube, and whereby compressed air or gas can be introduced between the support tube and the membrane and can escape into the liquid that is to be gasified via slits in the membrane

AI summary
An apparatus for the gasification or aeration of liquids. Elongated aeration elements are connected to a distribution conduit and have an essentially rigid support tube having a lengthwise rounded groove about which is disposed a membrane of elastomeric material. Compressed gas introduced between the support tube and membrane escapes via slits in the membrane. An elastically deformable flange of a cylindrical portion of a fitting with a plastic semi-rigid saddle portion is disposed between the distribution conduit and one of the aeration elements, and is disposed in a bore in the conduit. The fitting has an essentially flat saddle portion, one side of which rests against the outer surface of the conduit, and the other side of which rests against an end of the aeration element. A hollow bolt is securely connected to the aeration element and is guided through a bore in the fitting into the interior of the conduit, where it is provided with apertures.
