Detergent Solution Filtration System for Container Washing Plants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current detergent solution treatment systems in washing and rinsing plants for containers require frequent maintenance, downtime, and high energy consumption, as they struggle to effectively remove suspended solid particles without interrupting production cycles, leading to inefficient operation and environmental impact.
Innovation Solution
A treatment system that includes a primary rotating drum filter with wedge wire elements and a secondary self-cleaning static ring filter, controlled by a unit that manages the flow and recirculation of the detergent solution, allowing continuous operation and extended solution usage by maintaining solution quality through selective filtration and counter-washing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a treatment system is implemented to remove suspended solid particles from detergent solution, then the solution quality is improved, but the device complexity increases
Solution Approach 1:
The treatment system is divided into two independent filtration stages: a first filtering means with a first mesh opening and a second filtering means with a second mesh opening. This segmentation allows each filter to target specific particle sizes, improving overall solution quality while keeping individual filter units relatively simple and manageable.
Solution Approach 2:
The treatment system is designed to be integrated into the existing detergent solution circulation circuit of the washing/rinsing plant, serving multiple functions: filtering suspended particles, extending solution life, and maintaining washing efficiency. The system works continuously with the production cycle without requiring separate dedicated equipment.
2Reliability
If frequent maintenance is performed to keep the system operating, then the reliability is improved, but the loss of time increases
Solution Approach 1:
The treatment system operates continuously throughout the washing/rinsing production cycle without interruption. The filtering means are integrated into the circulating detergent solution flow, allowing filtration to occur continuously as solution is pumped from the tank through the filters and returned to the tank, eliminating the need for periodic shutdowns for maintenance.
3Productivity
If high energy consumption is used to maintain solution quality, then the productivity is improved, but the use of energy increases
Solution Approach 1:
The system uses two filtering means with different mesh openings to handle different levels of particle removal. The first filter with larger mesh opening removes coarse particles, while the second filter with smaller mesh opening removes finer particles. This staged approach achieves thorough filtration and extends solution life without requiring excessive energy input that would be needed for a single high-performance filter.
