Oxygenating Hull with Cross Member for Fish Breeding Tanks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mixer-oxygenator devices for fish breeding tanks suffer from oxygen wastage as delivered oxygen often escapes and does not effectively bond with water, leading to reduced oxygenation and increased costs.
Innovation Solution
The apparatus features a partially sinkable hull with adjustable floating bodies, a rotating drum with radially protruding blade and wing elements, and a cross member or dividing wall to optimize oxygenation by recirculating and remixing oxygenated water, reducing oxygen loss and enhancing oxygen absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If an internal rotating drum with radially protruding wings is used to atomize water and increase oxygen surface area, then oxygenation efficiency is improved, but oxygen is wasted as it escapes outside the hull without bonding with water
Solution Approach 1:
The drum is segmented into multiple radially protruding wings that divide water into multiple streams and droplets, increasing the surface area for oxygen absorption while containing the oxygenation process within the hull boundaries
Solution Approach 2:
The hull acts as an intermediary chamber that confines and recirculates oxygenated water, ensuring that delivered oxygen remains in contact with water droplets until absorption is complete, preventing oxygen escape
2Quantity of substance
If water is lifted and divided into drops to increase surface area for oxygen bonding, then oxygen absorption is enhanced, but oxygen delivery cost increases due to waste
Solution Approach 1:
The system maintains continuous recirculation of water within the hull, ensuring that oxygen delivered to the water remains in contact with water droplets until absorbed, eliminating waste and maximizing the utility of each oxygen delivery event
Solution Approach 2:
The recirculation mechanism provides feedback by returning oxygenated water back to the atomization zone, allowing multiple passes of oxygen through the water until saturation is achieved, thereby reducing overall oxygen delivery requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design significantly increases water oxygenation while minimizing oxygen waste, providing healthier aquatic conditions with reduced operational costs.
Implementation Method 1
an internal rotating drum which has different radially protruding wings or the like so as to atomise the water as much as possible to thus create a greater surface of attack for the oxygen
Implementation Method 2
the oxygen bonds with these water particles, increasing the oxygen concentration thereof
Implementation Method 3
at least one floating body (3) incorporated into or connected to said hull (2) so as to maintain said hull (2) in floating state on the water

AI summary
An apparatus (1) for agitating and oxygenating water, comprising a hull (2) that is overturned and is in use partially sinkable in water and in which said hull (2) defines an inner volume (V) and has an upper surface (2a) and a lower face (2b) open towards the water. The hull (2) comprises at least one cross member (7) extending along a direction that is substantially parallel to the surface of the water (100) and transverse to a direction of main extension direction (E) of the hull (2), in which said cross member (7) is arranged in the inner volume (V) of the hull (2) and is vertically distanced from the upper surface (2a) by a preset distance so as to define a passage (P) for recirculating water drops rising from the surface of the water (100) to the hull (2) and passing between said cross member (7) and the rear surface so as to increase oxygenation of the water.
