Rotating Swing-Nozzle Cleaning for Stirring Tank Residue Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning methods for stirring tanks in the lithium battery industry suffer from incomplete cleaning and low cleaning efficiency, leading to potential contamination of new slurry by old slurry residues.
Innovation Solution
A cleaning apparatus with a rotatable mounting base and nozzles that can move under a driving mechanism, allowing for effective cleaning of the stirring tank by rotating and swinging the nozzles to cover a larger cleaning range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a solvent is added into the stirring tank to clean the inside of the stirring tank in conjunction with stirring with a stirring paddle, then the cleaning process is simple, but the cleaning completeness and cleaning efficiency are low
Solution Approach 1:
The patent applies dynamics by making the mounting base rotatable around a set direction, enabling the nozzles to dynamically change their cleaning position and coverage area. This rotational movement transforms a static cleaning system into a dynamic one, allowing comprehensive cleaning of the stirring tank interior without requiring complex disassembly or manual intervention, thus improving cleaning efficiency while maintaining operational simplicity
Solution Approach 2:
The patent introduces another dimension by adding rotational movement around a set direction to the cleaning apparatus. This dimensional addition allows the nozzles to cover a broader cleaning range by rotating, effectively transforming a single-point cleaning approach into a multi-position cleaning system that addresses all interior surfaces of the stirring tank more efficiently
2Ease of manufacture
If a solvent is added into the stirring tank to clean the inside of the stirring tank in conjunction with stirring with a stirring paddle, then the cleaning process is simple, but the cleaning completeness is insufficient
Solution Approach 1:
The rotational capability of the mounting base enables the nozzles to dynamically access different positions and angles within the stirring tank, ensuring comprehensive coverage of all interior surfaces. This dynamic positioning resolves the issue of incomplete cleaning by allowing the cleaning apparatus to reach areas that would be inaccessible to a fixed or simple stirring-based cleaning method
Solution Approach 2:
The patent applies local quality by positioning multiple nozzles on the mounting base at different locations and orientations. Each nozzle can be directed toward specific areas of the stirring tank interior, ensuring that local regions are thoroughly cleaned. This distributed nozzle arrangement complements the simple stirring process to achieve complete cleaning coverage
