Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concentrating apparatuses for ternary precursor particles suffer from low solid particle content, limited flow rate, product loss, and poor production efficiency due to the baffle settlement mode used for concentration.
Innovation Solution
A filtering and concentrating apparatus with a stirring function is introduced, featuring a barrel with microporous filtering mediums and a stirring mechanism. This design allows for high solid particle concentration, accelerated feed flow, and reduced product loss, enabling increased feeding capacity and improved production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the baffle settlement mode is used for concentration, then the feed liquid can be settled by limiting the overflow velocity, but the flow rate of feeding must be controlled not to be high, resulting in low production efficiency
Solution Approach 1:
The patent uses microporous filtering mediums (filtering pipes with microporous filtering medium wrapped around them) installed on the inner wall of the barrel to concentrate solid particles. The microporous structure allows liquid to pass through while retaining solid particles, achieving high solid particle content without limiting the feed flow rate, thus resolving the contradiction between quantity of substance and productivity
Solution Approach 2:
The patent extracts the filtering function from the traditional baffle settlement mode and implements it through dedicated filtering pipes with microporous filtering mediums. This separation allows the settling process to occur independently through the filtering pipes while the main feed flow continues uninterrupted, enabling high solid particle concentration without restricting overall feeding capacity and maintaining high production efficiency
2Productivity
If the flow rate of feeding is increased, then the feeding capacity of the reactor can be increased, but the feed liquid flows out of the overflow port before crystallizing and settling, resulting in product loss
Solution Approach 1:
The filtering pipes are installed in advance on the inner wall of the barrel, positioned to intercept solid particles before they reach the overflow port. This preliminary filtration action ensures that even at high feed rates, solid particles are captured by the microporous filtering mediums before they can escape through the overflow, preventing product loss while maintaining high feeding capacity
Solution Approach 2:
The microporous filtering mediums act as an intermediary between the feed liquid and the overflow port. They intercept and retain solid particles while allowing liquid to pass, serving as a mediating structure that enables high flow rates without product loss by preventing direct escape of solids through the overflow
