Rotating Cleaning Head Fluid Distributor for Uniform Spray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotating cleaners in the process industry face challenges in achieving a uniform and efficient spray pattern due to the occurrence of eddies in the cleaning liquid, leading to incomplete surface wetting and reduced cleaning effectiveness.
Innovation Solution
A rotating cleaner design featuring a fluid distributor with a hollow body and dome-like end face, arranged to rotate with the spray body, which includes evenly distributed openings to minimize eddies and pressure loss, and a plain bearing for uniform rotation, along with a stainless steel construction for durability and hygiene, and a one-piece shaft and fluid distributor for simplified assembly and reduced fouling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cleaning fluid flows directly through the spray body without a fluid distributor, then the structure is simpler, but eddies and vortices form in the cleaning liquid leading to poor spray pattern
Solution Approach 1:
A fluid distributor is introduced as an intermediary component between the shaft and the spray body. This fluid distributor has multiple openings that distribute the cleaning fluid evenly across the spray body interior, preventing eddies and vortices from forming. The fluid distributor acts as a mediator that transforms the direct flow into a distributed flow pattern, improving spray quality without significantly complicating the overall structure.
2Device complexity
If the fluid distributor is stationary, then the structure is simpler, but the distribution of cleaning liquid becomes less uniform during rotation
Solution Approach 1:
The fluid distributor is designed to rotate together with the spray body instead of remaining stationary. This dynamic configuration ensures that the fluid distributor maintains its relative position to the spray body throughout the rotation, providing consistent and uniform fluid distribution across all areas of the spray body interior regardless of the rotation angle.
3Ease of manufacture
If the shaft and fluid distributor are separate components, then assembly is easier, but more interfaces create fouling risks and increase complexity
Solution Approach 1:
The shaft and fluid distributor are merged into a single integrated component. This one-piece construction eliminates the interface between the shaft and fluid distributor, removing potential fouling points where cleaning liquid could stagnate. The integration reduces the total number of components and assembly steps while improving hygienic properties by eliminating crevices and joints that could trap dirt or bacteria.
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
The design achieves a significantly improved spray pattern with reduced turbulence and vortices, ensuring thorough surface wetting and enhanced cleaning efficiency while meeting hygienic and operational standards.
Implementation Method 1
A fluid distributor designed for the even distribution of fluid is arranged in the interior of the spray body. The uniform distribution of the cleaning liquid in the interior of the spray body caused by the fluid distributor reduces the occurrence of eddies in the cleaning liquid to a considerable extent.
Implementation Method 2
The shaft is rotatably supported in the housing with a bearing. A plain bearing for uniform rotation is used.
Implementation Method 3
The cleaning fluid passes through the hollow shaft from the housing into the interior of the spray body.
