Eccentric Impact Body Nozzle Manifold for Hygienic Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing nozzle bar design for generating liquid jets is prone to bacterial contamination in the pressure distribution chamber, especially when using certain fibers like cotton, leading to difficult and disruptive cleaning processes, as the impact body is intricately secured and requires full disassembly for removal.
Innovation Solution
The impact body is arranged eccentrically within the pressure distribution chamber using spacers, allowing it to be easily inserted and removed without disassembling the entire nozzle bar, enabling simpler cleaning and maintenance by eliminating the need for screws and countersunk holes, which reduces turbulence and facilitates disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the impact body is firmly screwed into the pressure distribution chamber, then the impact body is securely fixed in position, but the cleaning process becomes extremely complex and requires full disassembly of the lower part
Solution Approach 1:
The impact body is separated from the pressure distribution chamber as a removable component rather than being permanently fixed. The lower part of the nozzle bar is divided into separable sections, allowing the impact body to be accessed and removed independently through an opening in the first section, eliminating the need to disassemble the entire lower part for cleaning purposes.
2Reliability
If the impact body is removed for cleaning, then the pressure distribution chamber can be cleaned, but production interruptions last for hours due to complex disassembly
Solution Approach 1:
The lower part of the nozzle bar is segmented into at least two sections, with the impact body accessible through an opening in the first section. This allows the impact body to be removed and reinserted independently without disassembling the entire lower part, significantly reducing cleaning time and maintaining production continuity.
Solution Approach 2:
The impact body is designed to be removable through a pre-provided opening in the first section of the lower part, allowing cleaning to be performed as a preliminary maintenance action without affecting production. The opening is specifically designed to facilitate quick access for cleaning operations.
3Manufacturing precision
If the impact body is eccentrically arranged to reduce turbulence, then liquid flow becomes smoother, but the impact body requires secure fixation mechanisms
Solution Approach 1:
The impact body is designed as a separate, removable component that can be easily positioned in an eccentric arrangement within the pressure distribution chamber. The segmentation allows for simple fixation mechanisms rather than complex integrated structures, maintaining flow uniformity while reducing overall system complexity.

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 ensures a smoother, turbulence-free liquid flow and allows for effective cleaning of the pressure distribution chamber without interrupting production, maintaining high hygienic standards and improving the quality of water jets by preventing bacterial contamination.
Implementation Method 1
a pressure distribution chamber is provided with an intermediate wall, which is connected to the pressure chamber via liquid flow bores arranged in the intermediate wall
Implementation Method 2
which are pushed onto the impact body as perforated metallic rings with a spacer ring open at the bottom and are arranged at certain intervals

AI summary
A nozzle bar is described on a device for generating liquid jets for jet interlacing of the fibers of a fiber web, wherein a pressure distribution chamber is provided which is connected to the pressure chamber via liquid flow bores arranged in the intermediate wall, and the pressure distribution chamber terminates in a slot at the area opposite the liquid flow bores, which opens onto the bores of the nozzle plate, and in the pressure distribution chamber between the liquid flow bores and the slot a baffle body is arranged over the length of the slot, which is arranged in the pressure distribution chamber so that it can flow freely around it over its length and over its cross-section, and the baffle body is not screwed to the nozzle bar, but can be inserted into it and pulled out of it, being held in a centric or eccentric position by spacers.
