Modular Spinning Beam With Transverse Pump And Boiler
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinning beams have a large space requirement due to the arrangement of spinning beam modules and components, making maintenance and adaptation to increased capacity difficult and costly.
Innovation Solution
A modular spinning beam design where the pump, boiler, and spin packs are arranged in a compact assembly, allowing for easy installation and maintenance, with the pump and boiler positioned transversely or perpendicularly to the frame, reducing space requirements and enabling flexible expansion of installation capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If spinning beam modules are arranged side by side with sufficient space for maintenance access, then ease of maintenance is improved, but space requirement and device complexity increase
Solution Approach 1:
The pump is repositioned from a horizontal arrangement between spin packs to a vertical arrangement above the spin packs, utilizing the vertical dimension to eliminate the need for horizontal maintenance space while preserving accessibility for servicing
2Ease of repair
If pump and boiler are arranged on separate supports at distance from housing, then ease of maintenance is improved, but dwell time increases and space requirement increases
Solution Approach 1:
The pump and boiler are integrated into a single modular assembly that is mounted directly on the spinning beam housing, eliminating the need for separate support structures and reducing the overall distance between components while maintaining maintenance accessibility
3Reliability
If spinning beam modules are fixedly connected via pipes for heat transfer medium, then reliability is improved, but adaptability to increased capacity and ease of manufacture deteriorate
Solution Approach 1:
The spinning beam is divided into modular assemblies that can be independently installed and configured, allowing flexible adaptation to different production capacities without requiring complete redesign of the entire system
Solution Approach 2:
The modular design allows the spinning beam to be dynamically configured and expanded by adding or removing modules as production capacity requirements change, rather than being fixed during manufacturing
4Ease of repair
If heating rods and pump require space for replacement, then ease of maintenance is improved, but device complexity and space requirement increase
Solution Approach 1:
The pump is positioned vertically above the spin packs rather than horizontally between them, allowing maintenance personnel to access and replace the pump from above without requiring horizontal clearance space, thereby simplifying the overall structural requirements
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 modular design simplifies maintenance, reduces space requirements, and allows for easy adaptation of production capacity by enabling closer arrangement of components, resulting in shorter melt lines and dwell times for liquid plastics material.
Implementation Method 1
at least the pump and the spin pack are heated by a heat transfer medium which is heated in a boiler
Data Source
AI summary
A spinning beam for producing melt-spun filaments, in which liquid plastics material is conveyed via an externally arranged extruder to at least one pump, which conveys the liquid plastics material to at least one spin pack having a spinneret, at least the pump and the spin pack being heated by a heat transfer medium which is heated in a boiler. The pump, the boiler and an opening for receiving a spin pack are arranged in a modular assembly, which can be installed and fixed singly, or in a plurality one behind the other, in a frame of the spinning beam.
