Flexible Filter Waste Bin for Slurry Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disposal of waste slurry from industrial processes, particularly residual ready-mixed concrete, poses challenges as it often contaminates groundwater and clogs stormwater drains due to the mixing of particulate matter and contaminated liquid, requiring effective separation and handling solutions.
Innovation Solution
A slurry handling and disposal system featuring a waste bin with a flexible removable filter element that retains particulate matter and allows liquid to be collected separately, equipped with lifting fixtures, a mesh basket-like filter support structure, and liquid discharge means for efficient separation and transport of waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If waste slurry is discharged directly to construction site or drains, then disposal is simple and quick, but it causes environmental contamination and drain blockage
Solution Approach 1:
The waste slurry is segmented into two distinct components: particulate matter retained on the filter element and liquid that passes through to the base portion. This separation allows each component to be disposed of appropriately - particulate matter in the filter bag and liquid through the discharge port - eliminating environmental harm while maintaining efficient disposal.
Solution Approach 2:
The filter element acts as an intermediary between the waste slurry and the environment. It selectively allows liquid to pass through while retaining particulate matter, preventing direct discharge of contaminated material into the environment and enabling compliant waste disposal.
2Reliability
If filter element is made permanent, then separation efficiency is maintained, but removal and replacement of filter becomes difficult
Solution Approach 1:
The filter element transitions from a fixed permanent state to a dynamic removable state. The retaining mechanism allows the filter to be securely held during operation for reliable separation, then easily removed when needed for replacement, combining the benefits of both permanent and temporary filter systems.
Solution Approach 2:
The filter element is designed to be discarded after use and replaced with a fresh one. The removable design facilitates easy disposal of saturated filters and installation of new filters, maintaining separation efficiency without the complexity of cleaning and maintaining permanent filters.
3Reliability
If filter support structure is complex, then filter retention is secure, but device complexity increases
Solution Approach 1:
The support structure is segmented into simple modular components: a base portion and upright portions forming a basket-like framework. This segmented design provides secure filter retention through multiple contact points while keeping each individual component simple and easy to manufacture.
Solution Approach 2:
The filter element itself acts as a flexible membrane that conforms to the basket-like support structure. This flexible filter adapts to the simple geometric framework, allowing secure retention without requiring complex rigid support mechanisms.
