Cooler Duct Filter Layout for Faster Cleaning and Stable Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing coolers in false-twist texturing machines suffer from reduced operational efficiency due to the need for manual cleaning of filters, which is cumbersome and time-consuming, leading to decreased performance of the suction device as foreign matters accumulate.
Innovation Solution
A cooler design with a detachable filter mechanism that allows for easy removal and replacement, featuring a lid and elastic member to secure the filter in place, along with guide members for positioning and a fixing mechanism to prevent unintended opening, ensuring efficient filter maintenance and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is fixed to the suction port to prevent foreign matter entry, then the suction device protection is improved, but the filter cleaning workability deteriorates
Solution Approach 1:
The filter is designed as a detachable component separated from the suction device, allowing it to be removed independently for cleaning. The filter can be detached from the duct and cleaned externally without disassembling the suction device, thus maintaining protection during operation while enabling easy maintenance.
Solution Approach 2:
The filter is extracted from the suction device structure and positioned in the duct where it can be easily accessed for removal. This allows the filter to be taken out for cleaning without affecting the suction device, resolving the contradiction between maintaining protection and enabling easy cleaning.
2Productivity
If the filter is regularly cleaned to maintain suction performance, then the operational efficiency is improved, but the maintenance time increases
Solution Approach 1:
The filter cleaning process is segmented from the main operational workflow. The filter can be quickly detached and cleaned separately without requiring shutdown of the entire system or complex disassembly, reducing maintenance time while maintaining operational efficiency.
Solution Approach 2:
The filter design allows for simple self-service cleaning where the filter can be easily removed, cleaned, and reinstalled by operators without requiring specialized tools or extensive training, minimizing maintenance time and maintaining productivity.
3Ease of operation
If the filter is detachably provided in the duct to improve cleaning access, then the filter cleaning ease is improved, but the device complexity increases
Solution Approach 1:
The duct structure is segmented to include a specific filter installation position with a duct opening, allowing the filter to be detachably mounted. This simple structural modification enables easy filter access without significantly complicating the overall duct design.
Solution Approach 2:
The filter is extracted to a position in the duct where it can be easily accessed through a duct opening, allowing simple attachment and detachment. This minimal structural addition provides easy cleaning access without requiring complex mechanisms or significant redesign of the duct system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design improves filter cleaning workability, reduces maintenance time, and enhances operational efficiency by allowing quick filter replacement and preventing foreign matter intrusion into the suction device.
Implementation Method 1
an elastic member sandwiched between the lid and the filter when the lid closes the duct opening, and the filter being biased toward the supporting surface by restoring force of the elastic member
Implementation Method 2
a suction device connected to one end portion of the duct and capable of sucking gas in an in-duct space of the duct

AI summary
An object is to improve the operational efficiency. A duct 31, cooling units 33 aligned in an extending direction of the duct 31, a suction device 32 connected to one end portion of the duct 31 and capable of sucking air in an in-duct space Sa, and a filter 34 arranged to allow the air sucked by a suction port 32a of the suction device 32 to pass through. The in-duct space Sa is connected to yarn running spaces Sb formed in the respective cooling units 33, in a direction perpendicular to the extending direction of the duct 31. The filter 34 is detachably provided between (i) a yarn running space Sb closest to the suction port 32a among the yarn running spaces Sb and (ii) the suction port 32a. The duct 31 has a maintenance opening 31a1 which is formed between the yarn running space Sb at the end and the suction port 32a. Furthermore, a lid 36 that can close the maintenance opening 31a1 is provided.
