Textile Intake System Sealed Waste Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intake systems for textile machines face challenges in maintaining constant negative pressure and efficient filtration, leading to suboptimal yarn quality and increased operational costs due to manual and labor-intensive filter cleaning, as well as the need for redundant systems and increased energy consumption as filters clog over time.
Innovation Solution
The intake system employs sealed conveying means, such as rotary valves or spiral screws, to maintain filtration devices under constant negative pressure, ensuring continuous separation and removal of waste without clogging, and incorporates a cyclone device for efficient air flow separation, allowing for automatic and continuous cleaning without interrupting machine operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal inertial-type filters are used to suction dust and waste, then filtration efficiency is high initially, but loss of load increases and power consumption increases as dust accumulates on the filter
Solution Approach 1:
The patent implements periodic reverse flushing of the filter using a cyclone device that periodically reverses the air flow direction. This periodic action removes accumulated dust from the filter screen, restoring filtration efficiency and reducing power consumption without requiring manual intervention or system shutdown.
Solution Approach 2:
The filter cleaning system is self-service, automatically removing dust accumulation through the cyclone-generated reverse flow. The system monitors and executes cleaning cycles autonomously, eliminating the need for manual cleaning operations and maintaining consistent filtration performance without external intervention.
2Ease of manufacture
If manual filter cleaning is performed, then filter maintenance is achieved, but labor costs increase and machine operation may be interrupted
Solution Approach 1:
The system performs self-maintenance through automatic reverse flushing of the filter using cyclone-generated reverse air flow. This eliminates manual cleaning operations entirely, reducing labor costs and preventing interruptions to machine operation, as the cleaning occurs automatically during normal operation or without production impact.
Solution Approach 2:
The filter cleaning operation is integrated into the continuous operation of the machine. The reverse flushing can occur during idle periods or in a manner that does not interrupt the spinning process, ensuring continuous productive action while maintaining filter performance without stopping the machine.
3Reliability
If redundant filtration systems are installed to maintain constant negative pressure, then operational reliability improves, but device complexity and cost increase
Solution Approach 1:
Instead of using redundant filter systems, the patent employs periodic reverse flushing of the single filter to maintain its performance. This periodic regeneration maintains constant negative pressure and filtration reliability without requiring duplicate filtration systems, thereby reducing device complexity and cost while achieving the same reliability outcome.
4Device complexity
If filter cleaning is delayed or performed manually, then system simplicity is maintained, but yarn quality deteriorates due to ununiform negative pressure
Solution Approach 1:
The system automatically monitors and cleans the filter through reverse flushing, maintaining uniform negative pressure without manual intervention. This self-service mechanism ensures consistent yarn quality by preventing pressure variations that would occur with delayed or manual cleaning, while adding minimal complexity to the overall system.
