Isolation Type Tunnel Washer Design to Reduce Bacterial Spread
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tunnel washers fail to effectively isolate pathogenic bacteria in the air during the washing process, leading to potential secondary pollution and hazards to operators.
Innovation Solution
The isolation type tunnel washer incorporates a closed box body with a partition wall, a water vapor separation structure, and an air blowing structure. The water vapor separation structure extracts air from the tunnel washer before the discharge door is opened, and the air blowing structure blows air inward to prevent bacterial-carrying air from escaping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the air in the tunnel washer is directly discharged after washing, then the operation is simple and fast, but pathogenic bacteria spread to the surrounding environment causing secondary pollution
Solution Approach 1:
The tunnel washer is divided into a washing cavity and a discharge cavity by a partition wall with a water vapor separation structure. This segmentation isolates the bacterial source in the washing cavity from the discharge path, allowing rapid air discharge while preventing bacterial spread through the separated discharge cavity design.
Solution Approach 2:
The water vapor separation structure acts as an intermediary between the washing cavity and discharge cavity. It processes and separates air before discharge, filtering out water vapor and bacteria while allowing clean air to pass through, thus preventing bacterial spread without compromising washing efficiency.
2Reliability
If sterilization particles are added to the tunnel washer, then sterilization effect is achieved, but the structure becomes complex and cannot prevent pathogen leakage during operation
Solution Approach 1:
The harmful water vapor and bacteria are extracted from the air flow through the water vapor separation structure. By removing these contaminants before discharge, the system achieves sterilization without needing complex sterilization particle mechanisms, simplifying the overall structure while maintaining reliability.
3Productivity
If the discharge door is opened immediately after washing, then the operation is fast and efficient, but bacteria-carrying air escapes to the surrounding environment
Solution Approach 1:
The water vapor separation structure performs preliminary action by processing and separating air before the discharge door opens. This pre-treatment removes bacteria and water vapor from the air flow, allowing the discharge door to open immediately for fast operation without risking bacterial escape.
Solution Approach 2:
The water vapor separation structure serves as an intermediary that mediates between the washing cavity and external environment. It processes air flow and blocks bacteria while allowing rapid discharge, enabling fast door opening without bacterial escape.
4Object-generated harmful factors
If a partition wall is added to separate the washing area, then bacterial isolation is improved, but the device complexity increases
Solution Approach 1:
The partition wall is merged with the water vapor separation structure to form an integrated component. This combination achieves bacterial isolation through the partition while the integrated water vapor separation structure handles air processing, reducing overall structural complexity compared to separate components.
