Lateral Access Collection Head for Filtration Tank Powder Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtration and drying tanks face challenges in efficiently recovering residual powdery products due to manual scraping operations, which are labor-intensive, risky, and inefficient, especially for high-value powders, and existing mechanical methods are limited by the need for disassembly and confined access.
Innovation Solution
A collection system with a collection head, handling arm, collection tube, and suction system is used to recover residual powders via a lateral access, utilizing a glove box and a suction system with a balancing Venturi to manage gas flow, allowing efficient and ergonomic recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual scraping is used to recover residual powdery products, then the operator can access the tank through a glove box, but the operation is time-consuming and carries risks of musculoskeletal disorders
Solution Approach 1:
The patent replaces manual mechanical scraping with a pneumatic suction system. A collection head connected to a vacuum source draws residual powdery products through a collection tube into a collection container, eliminating the need for manual scraping operations and associated ergonomic risks while significantly reducing operation time
Solution Approach 2:
The invention uses pneumatic principles to create a vacuum-driven suction system. The vacuum source generates negative pressure that draws residual products through the collection head and tube, providing a rapid and contactless method for heel recovery that avoids manual labor while maintaining operational efficiency
2Quantity of substance
If a porous recovery bag is used in the glove box, then waste and deposits can be recovered, but high-value powdery products cannot be effectively recovered
Solution Approach 1:
The patent employs a flexible collection bag as part of the collection container system. This flexible membrane structure allows the collection head to effectively reach and suction residual products from difficult-to-access areas of the tank bottom while maintaining product integrity, enabling complete recovery of high-value powders without the limitations of rigid or porous structures
Solution Approach 2:
The system replaces the inadequate porous bag approach with a vacuum-driven pneumatic transport system that actively draws products through sealed pathways, preventing product loss and enabling complete recovery of high-value materials while maintaining quantitative accuracy
3Productivity
If the tank bottom is disassembled for access, then complete scraping can be performed, but the device complexity and operation time increase
Solution Approach 1:
The patent introduces a lateral access opening that provides a new dimensional approach to reaching the tank bottom. Instead of disassembling the bottom vertically, the collection head accesses the bottom area through a side opening, enabling complete heel recovery without tank disassembly and reducing operational complexity while maintaining productivity
4Ease of operation
If a lateral access opening is created near the bottom, then the collection head can access residual products without disassembly, but the tank structure becomes more complex
Solution Approach 1:
The patent segments the access function by creating a dedicated lateral opening specifically for heel collection purposes. This separate access point is integrated into the existing tank structure and allows the collection head to reach the bottom area independently, improving operational ease while maintaining overall tank structural integrity with minimal modification complexity

Function Achieved in This Case
The system enables rapid and complete recovery of residual powders with improved ergonomics and containment, reducing the risk of musculoskeletal disorders and ensuring high recovery efficiency without damaging high-value products.
Implementation Method 1
a suction system associated with the collection tube for sucking up the residual powdery products via the collection head and for conveying said residual powdery products to the collection container via the collection tube
Implementation Method 2
a balancing Venturi mounted in the outlet pipe and powered by the gas device, to suck the gas into the collection container and thus balance the gas flow rates entering and leaving the collection container
