Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for loading solid particles into reactors face challenges in achieving dense, uniform, and efficient distribution, particularly due to dust generation and difficulties in closing the reactor safely, which necessitate a solution for introducing particles through a low-section orifice while maintaining compactness and control.
Innovation Solution
A device comprising a solid particulate supply hopper, a rotating member with rigid deflector elements pivotally mounted, and remote actuable deployment means to adjust the deflector elements' angle relative to the axis of rotation, allowing for precise control of particle distribution and maintaining compactness during introduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If rigid deflector elements are used to ensure efficient particle distribution, then the loading quality is improved, but the device size increases making it difficult to introduce through low-section orifices
Solution Approach 1:
The deflector elements are designed to be movable rather than fixed, allowing them to pivot between a retracted position (for compact device introduction) and a deployed position (for effective particle distribution). This dynamic configuration enables the device to adapt its size to the introduction orifice while maintaining functional performance during operation.
Solution Approach 2:
The deflector elements are configured to nest within or alongside each other when in the retracted position, allowing the entire assembly to pass through limited orifices. Once inside the reactor, they can be deployed to their functional positions, effectively nesting the functional components within a compact introduction envelope.
2Volume of moving object
If flexible materials are used to reduce device size for introduction, then the device compactness is improved, but the particle distribution efficiency deteriorates
Solution Approach 1:
The system transitions from a static flexible structure to a dynamic rigid structure. The deflector elements are rigid when deployed to ensure effective particle redirection, but can be retracted to achieve compact device size during introduction. This resolves the contradiction by making rigidity conditional rather than permanent.
Solution Approach 2:
The device is segmented into multiple independently controllable deflector elements that can be selectively deployed or retracted. This allows the device to present a compact profile during introduction while deploying only the necessary components for particle distribution during operation, maintaining both compactness and efficiency.
3Device complexity
If the deflector elements are fixed in position, then the device structure is simplified, but the adaptability to different rotation speeds and loading conditions is reduced
Solution Approach 1:
The deflector elements are designed with pivot mounting and remote actuation capabilities, allowing their position to be adjusted based on operational requirements. This dynamic positioning capability provides adaptability to different rotation speeds and loading conditions while maintaining a relatively simple overall device structure through modular design.
Solution Approach 2:
The system allows change in the angular position parameter of the deflector elements to optimize particle distribution under varying operating conditions. By enabling remote adjustment of the deflector angle, the system adapts to different rotation speeds and loading scenarios without requiring complex structural changes.
4Manufacturing precision
If multiple deflector elements are deployed to improve particle distribution uniformity, then the loading homogeneity is improved, but the device complexity and introduction difficulty increase
Solution Approach 1:
The device uses multiple segmented deflector elements that can be individually controlled. Each element is relatively simple in structure, but their coordinated deployment creates the complex particle distribution pattern needed for uniform loading. The segmentation allows each component to remain simple while achieving complex overall functionality.
Solution Approach 2:
Multiple deflector elements are designed with independent pivot and actuation mechanisms, allowing them to be deployed in a coordinated manner. This dynamic deployment strategy enables uniform particle distribution across the reactor cross-section while keeping each individual element structurally simple and the overall device manageable for introduction.
