Stirring Apparatus Guide Rod Vibration Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stirring arrangements in biogas plants and similar containers face instability issues due to the lack of resistance to external influences, particularly when dealing with viscous materials, which can cause the guide rod to vibrate and potentially damage the equipment.
Innovation Solution
A longitudinally displaceable sleeve is mounted on both the support column and guide rod, allowing for variable distance adjustment between the sleeve and the electric motor, providing mutual stabilization and preventing vibration of the guide rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the guide rod is made lighter to reduce overall weight, then the weight of the stirring arrangement is reduced, but the guide rod becomes more susceptible to vibration and damage from viscous materials
Solution Approach 1:
A stabilizing element (cuff/sleeve) is introduced as an intermediary component between the support column and guide rod. This stabilizing element provides additional support to the guide rod, enabling it to resist vibrations from viscous materials while keeping the guide rod itself lightweight. The stabilizing element acts as a mediator that transfers stability from the robust support column to the lighter guide rod.
2Reliability
If the guide rod is made stronger to resist vibration, then the stability and reliability of the guide rod is improved, but the overall weight of the stirring arrangement increases
Solution Approach 1:
The support structure is segmented into distinct functional components: a robust support column for overall structural support, a lighter guide rod for precise positioning, and a stabilizing element (cuff/sleeve) that provides localized reinforcement. This segmentation allows each component to be optimized for its specific function, with the guide rod remaining lightweight while the stabilizing element provides the necessary vibration resistance.
3Adaptability or versatility
If the electric motor is mounted longitudinally displaceable on the support column to adjust position, then the adaptability of the stirring arrangement is improved, but the stability of the motor position may be compromised
Solution Approach 1:
The stabilizing element (cuff/sleeve) serves as an intermediary that provides stable positioning for the electric motor while allowing longitudinal displacement. The motor can move along the support column for position adjustment, and the stabilizing element ensures that the motor maintains a stable and precise position during operation, preventing unwanted vibrations or positional drift.
