Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder transfer systems face limitations in continuously supplying a large amount of powdery active material for secondary battery manufacturing, with conventional methods unable to efficiently manage the transfer of both small and large quantities.
Innovation Solution
A vacuum-type powder transfer system with a storage part, chamber parts, and a hopper part, utilizing a vacuum pressure forming part to selectively guide powder to chamber or hopper parts through branch pipes, allowing for precise control of powder flow and distribution, including anti-abrasion plates to prevent wear, and weight sensors for accurate quantity management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional powder transfer system is used to discharge powder downstream after the storage part is filled to a predetermined volume, then the powder transfer amount can be precisely controlled, but the system cannot continuously supply a large amount of powder
Solution Approach 1:
The system divides the powder transfer path into multiple independent routes: a first transfer line for small amounts of powder and a second transfer line for large amounts of powder. This segmentation allows the system to handle different powder quantities through appropriate channels, enabling both precise control for small amounts and continuous supply for large amounts without interference between the two operations.
Solution Approach 2:
The system dynamically switches between different transfer lines based on the required powder supply amount. When small amounts are needed, the first transfer line is activated; when large amounts are needed, the second transfer line is activated. This dynamic configuration allows the system to adapt its transfer capability to match the actual production requirements, resolving the contradiction between precise control and continuous supply.
2Measurement precision
If a vacuum suction method is used to transfer powder, then precise control of powder transfer amount is achieved, but wear on transfer components occurs
Solution Approach 1:
The system introduces an intermediary powder collection container between the vacuum suction source and the final destination. The vacuum suction first collects powder into this intermediate container, which then dispenses the powder through controlled mechanisms. This intermediary structure protects the vacuum components from direct exposure to abrasive powder, reducing wear while maintaining precise transfer control.
Solution Approach 2:
The system employs disposable or easily replaceable components in the powder transfer path, particularly in areas subject to wear. By using consumable parts that can be quickly replaced rather than repaired, the system minimizes downtime and maintenance costs associated with wear on vacuum transfer components.
