Liner Discharge Structure for Bottom-Discharge Tanks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container liners face challenges such as difficulty in installation, interference with container operations, and incompatibility with certain fluids, particularly in bottom-discharge tanks with vertical spouts, which can lead to contamination and reduced usability.
Innovation Solution
A liner discharge structure featuring a neck collar, neck, and discharge collar made from the same material as the liner, encapsulating O-rings to prevent contamination and ensure compatibility, which is attached to the container liner to facilitate easy installation and prevent slipping during discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a liner is installed in a bottom-discharge tank with a vertical spout, then contamination is reduced, but the liner may slip and interfere with the discharge opening
Solution Approach 1:
The liner discharge structure is divided into distinct segments: a neck collar portion, a neck portion, and a discharge collar portion. Each segment serves a specific function - the neck collar seals around the vertical spout, the neck provides fluid passage, and the discharge collar seals at the discharge opening. This segmentation allows the liner to maintain contamination barriers while ensuring proper discharge operation without slipping or interference.
2Object-affected harmful factors
If the liner material is made compatible with specific fluids, then contamination is prevented, but the liner may slip within the tank
Solution Approach 1:
The liner discharge structure employs local quality by creating specific geometric features at critical locations: the neck collar with its configured shape provides localized sealing contact with the vertical spout, while the discharge collar provides localized sealing at the discharge opening. These localized structural adaptations ensure both fluid compatibility (contamination prevention) and structural stability (preventing slips) without requiring changes to the overall liner material composition.
3Stability of the object's composition
If a liner discharge structure with multiple components is used, then stability and compatibility are improved, but device complexity increases
Solution Approach 1:
The neck collar portion, neck portion, and discharge collar portion are merged into a single integrated liner discharge structure that is formed as one continuous component from the liner material. This merging approach maintains the stability and compatibility benefits of having multiple functional sections while eliminating the complexity of assembling separate components, as the entire structure is created in a single manufacturing process.
