Multi-Chamber Grease Trap with Residue Separation and Manual Scrapers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grease separation systems for catering wastewater in small- to medium-scaled industries in Hong Kong have inadequate grease removal efficiency, lack residue separation capabilities, and often become blocked due to deposited food residue and lack of effective discharge mechanisms, leading to foul smells and cleanliness issues.
Innovation Solution
A residue and grease trap with multiple chambers, including a residue trap chamber, three grease trap chambers, and features such as a residue separation mesh, manually-operated grease scrapers, grease discharge pipes, adjustable legs, and air vents, allowing for efficient separation and removal of grease and residue, with improved discharge mechanisms and pressure balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional two-chamber grease traps are used, then the device complexity is low, but the grease separation efficiency is insufficient and residue accumulates causing blockages
Solution Approach 1:
The grease trap is divided into multiple functional chambers: a residue trap chamber for food residue, a grease trap chamber for grease separation, and a clean water chamber for discharged water. This segmentation allows each chamber to perform its specific function efficiently, resolving the contradiction by increasing separation efficiency through functional division rather than using a single complex chamber
2Reliability
If no residue discharge pipe is provided, then the device complexity is low, but residue accumulates on the bottom causing blockages and foul smells
Solution Approach 1:
Residue discharge ports are pre-configured at the bottom of both the residue trap chamber and grease trap chamber, allowing residue to be discharged before it accumulates and causes blockages. This preliminary discharge capability prevents the harmful effect of residue accumulation without requiring complex active discharge mechanisms
3Productivity
If no grease scraper is provided, then the device complexity is low, but grease accumulates on water surface reducing separation efficiency
Solution Approach 1:
The grease scraper is designed to be manually operated by the user, allowing them to remove accumulated grease from the water surface themselves. This self-service approach enables effective grease removal without requiring complex automated scraping mechanisms, resolving the contradiction between removal efficiency and device complexity
4Productivity
If the trap is not adjustable, then the device complexity is low, but improper installation angle reduces grease separation efficiency
Solution Approach 1:
Adjustable legs are provided at the bottom of the grease trap, allowing the installation angle and position to be dynamically adjusted during installation. This enables the trap to be properly leveled and positioned for optimal grease separation performance without requiring a complex adjustable mechanism during operation
