Movable Air-Water Separation Drainage for Block-Free Dryer Screen Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage systems for cleaning heads in paper production plants suffer from blockages due to dirt particles and wastewater depositing on walls, requiring manual cleaning and disrupting the drainage process.
Innovation Solution
A drainage device with an air-water separation container connected to the cleaning head, allowing for air and wastewater separation close to the cleaning head, minimizing path length and preventing desiccation or coating of dirt particles, and featuring a tubular body with propellant inlets to enhance flow and prevent blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dirt particles and wastewater are carried into a rigidly installed collection container, then drainage is achieved, but deposits form on the walls requiring manual cleaning
Solution Approach 1:
The drainage device is made movable instead of rigid, allowing it to follow the cleaning head's transverse movements. This dynamic configuration prevents wastewater from stagnating and depositing on walls, eliminating the need for manual cleaning while maintaining continuous drainage efficiency
Solution Approach 2:
The system uses the cleaning head's own movement to automatically position the drainage device, eliminating the need for separate maintenance operations. The drainage device serves itself by being passively transported along with the cleaning head, ensuring continuous operation without manual intervention
2Productivity
If the path length for wastewater removal is increased, then drainage capacity is improved, but desiccation and coating of dirt particles occur
Solution Approach 1:
The drainage device is positioned immediately adjacent to the cleaning head, performing the drainage action at the very location where wastewater is generated. This preliminary action prevents wastewater from traveling through long paths where evaporation and desiccation could occur, maintaining high drainage capacity while avoiding particle coating
Solution Approach 2:
The drainage function is extracted from a distant rigid container and placed directly at the cleaning head location. This extraction eliminates the intermediate transport path that causes desiccation, allowing wastewater to be removed directly at the source with minimal travel distance

AI summary
A drainage device for removing dirt particles and wastewater from a cleaning head for cleaning a dryer screen of a paper production plant includes an air-water separation container. The air-water separation container includes an air outlet, a wastewater outlet and an inlet opening for receiving the dirt particles and the wastewater from the cleaning head. The air-water separation container is connected to the cleaning head so as to be movable transversely relative to the dryer screen together with the cleaning head.
