Filter-Press Electrolysis Unit With Smooth-Bore Tie-Rod Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of large-capacity electrolyzers is hindered by the need for precise alignment and accurate positioning of intermediate tie rods, which can cause interfering stresses and damage end plates, and the difficulty in removing these rods once tensioned, leading to slow on-site installation and increased costs.
Innovation Solution
The use of intermediate tie rods with smooth bores and heads, allowing for easy alignment and tensioning without interference, along with features like tapped bushings and hoist rings for secure handling and assembly, reduces assembly time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If intermediate tie rods with lugs and notches are used to compress electrolysis cells, then the electrolysis cells can be held together with sealing, but the alignment and positioning of the tie rods becomes complex and time-consuming
Solution Approach 1:
The intermediate tie rod is divided into a body portion and a head portion, where the body is a simple smooth rod and the head is a separate component that can be easily attached and removed. This segmentation allows the majority of the tie rod to remain simple while only the end portion requires complex features for connection.
Solution Approach 2:
The head of the intermediate tie rod is pre-formed with attachment features (such as threaded holes or coupling mechanisms) that enable quick connection to the electrolysis cell assembly. This preliminary preparation eliminates the need for complex alignment and positioning during actual assembly, as the head can be simply attached to the pre-positioned body.
2Strength
If intermediate tie rods are tensioned to compress electrolysis cells, then proper compression is achieved, but removing the tie rods becomes difficult due to lug jamming
Solution Approach 1:
The intermediate tie rod design allows the head to be dynamically attached and detached from the body. The head includes features that enable it to be securely fixed during compression but easily removed afterward, transforming a static rigid connection into a dynamic可拆卸 connection that adapts to different operational phases.
Solution Approach 2:
A separate head component acts as an intermediary between the tie rod body and the electrolysis cell assembly. This intermediary head can be independently attached and removed, facilitating easy disassembly without the need to manipulate the entire tie rod structure or deal with jammed lug connections.
3Stability of the object's composition
If electrolysis units are transported with end plates on horizontal surfaces, then stable transport is achieved, but assembly requires complex repositioning and handling
Solution Approach 1:
The intermediate tie rod extends in a direction perpendicular to the stacking axis of the electrolysis cells. This dimensional orientation allows the tie rod to provide structural support during horizontal transport while maintaining the vertical stacking configuration of the cells, enabling stable transport without requiring changes to the cell assembly geometry.
Solution Approach 2:
The intermediate tie rod serves multiple functions: it provides structural support during transport, enables compression of the electrolysis cells during assembly, and facilitates easy disassembly through its removable head design. This multi-functionality eliminates the need for separate handling procedures for different operational phases.
