Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for separating material from liquids, such as in water jet cutting and grinding processes, are inefficient and result in significant wear on mechanical parts, leading to suboptimal cleaning outcomes.
Innovation Solution
A separating device featuring a conveying element that can be guided along the floor by a drive, with a design minimizing mechanical wear by having the conveying element as the only mechanical part in the liquid, utilizing a basin with a curved bottom for material settlement and a chute system for efficient material collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a bag is used for cleaning with water directed through it so that sand settles inside, then material separation is achieved, but cleaning efficiency is low
Solution Approach 1:
The invention extracts the conveying element from the liquid environment, allowing it to be driven externally by a drive mechanism rather than requiring direct mechanical interaction with the liquid. This extraction principle enables more efficient material removal while reducing wear on mechanical components.
Solution Approach 2:
The invention replaces traditional mechanical mixing and separation systems with a driven conveying element that moves along the basin floor. This substitution reduces mechanical wear while improving cleaning efficiency by systematically transporting material to the outlet.
2Reliability
If multiple mechanical parts are located in the liquid for separation, then separation function is enhanced, but wear on mechanical parts increases
Solution Approach 1:
The conveying element is extracted from the liquid environment and driven externally, minimizing the number of mechanical parts in direct contact with the liquid. This reduces wear on mechanical components while maintaining effective separation function through the conveying element's movement along the basin floor.
Solution Approach 2:
The conveying element can be designed as a flexible component that moves along the basin floor, reducing the need for rigid mechanical parts in the liquid. This flexible approach minimizes wear while maintaining effective material conveyance.
3Productivity
If a curved bottom wall is used for material settlement, then material collection is improved, but device complexity increases
Solution Approach 1:
The basin bottom wall is designed with a curved surface that facilitates material settlement and convergence toward the outlet. This curvature naturally guides material flow without requiring additional mechanical components, improving collection efficiency while maintaining relatively simple device structure.

Function Achieved in This Case
The solution enables efficient separation of material from liquids with reduced mechanical wear, allowing for effective cleaning in various applications like water jet cutting and grinding, by using a conveying device that balances force requirements and facilitates easy liquid flow back into the system.
Implementation Method 1
Basin 10 serves as a trough into which liquid containing the material to be separated can be introduced, allowing it to settle at the bottom of the basin 10
Implementation Method 2
conveying element 21 for the conveying device 20, which is designed to receive and convey material M along a curved bottom surface 10c
Implementation Method 3
The arm 22 is thus balanced, so that conveying the material to be separated is possible with minimal force
