Trash Compactor Suction Line for Liquid Waste Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash compactors on passenger transport vehicles face challenges in separating and containing liquid waste from mixed waste, leading to messy and unsafe leakage, especially in confined spaces where space and safety are critical.
Innovation Solution
A trash compactor with a suction line or sloped platen to remove liquid waste from the upper surface during the compaction process, using vacuum or gravity drainage to prevent leakage and improve containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid extraction is attempted through the bottom of the compacting compartment, then liquid separation is achieved, but the elastomeric seals are destroyed by the platen pressure and residual liquid leaks during waste removal
Solution Approach 1:
The invention extracts the liquid removal function from the bottom extraction location and relocates it to the upper surface of the platen. A suction line is positioned at the upper surface to remove liquid directly from where it collects during compaction, avoiding the need for bottom extraction that destroys seals and causes leakage.
Solution Approach 2:
Instead of extracting liquid from the bottom of the compacting compartment as in conventional designs, the invention inverts the extraction location to the upper surface of the platen. This reverse approach allows liquid removal without compromising seal integrity and prevents leakage during waste removal.
2Volume of stationary object
If liquid and solid waste are contained together in the trash bin, then space is utilized, but liquid leakage creates messy and unsafe conditions in the confined galley space
Solution Approach 1:
The invention extracts liquid from the mixed waste during the compaction process using a suction line positioned at the upper surface of the platen. This continuous extraction prevents liquid accumulation and eliminates the hazard of liquid leakage, while still allowing solid waste to be compacted and contained in the trash bin.
3Reliability
If a screen or metallic filter is used at the base of the compactor for liquid extraction, then liquid separation is achieved, but removal of compacted solid waste becomes difficult and causes residual liquid leakage
Solution Approach 1:
The invention removes the screen or metallic filter from the base of the compactor and instead positions a suction line at the upper surface of the platen. This eliminates the obstruction that made waste removal difficult while maintaining effective liquid separation through vacuum suction.
Solution Approach 2:
Instead of using a screen or filter at the base of the compactor that obstructs waste removal, the invention inverts the liquid separation approach by using a suction line at the upper surface of the platen. This allows free removal of compacted waste without residual liquid leakage.
