Metal Pipe Exhaust Pit Layout to Reduce Discharge Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing forming apparatuses for metal pipes generate loud discharge noise when high-pressure gas is rapidly released, posing a noise hazard to workers.
Innovation Solution
A forming system with an underground pit structure that houses the exhaust port of the discharge unit, acting as a silencer to reduce noise pollution, and includes a configuration where the exhaust pipe is positioned within the pit, ensuring that discharge noise is contained and minimized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-pressure gas is rapidly discharged from the metal pipe to improve productivity, then the forming speed increases, but the discharge noise becomes loud and harmful to workers
Solution Approach 1:
The exhaust port is extracted from the ground level and relocated to an underground pit. The discharge unit includes an exhaust pipe positioned in the underground pit with the exhaust port facing upward, separating the noise-generating discharge process from the worker environment while maintaining rapid gas discharge for productivity
Solution Approach 2:
The underground pit acts as an intermediary structure between the discharge unit and the worker environment. The pit with water or other medium serves as a noise-absorbing intermediary that reduces the transmission of discharge noise to workers while allowing the high-pressure gas to be rapidly discharged
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 system effectively mitigates discharge noise issues by using the underground pit as a silencer, reducing noise exposure for workers and optimizing the space usage of the forming apparatus.
Implementation Method 1
an underground pit provided at a lower portion of the floor surface, in which an exhaust port of the discharge unit is positioned in an internal space of a structure having the internal space, and the discharge unit includes an exhaust pipe positioned in the underground pit as the structure and provided with the exhaust port
