Fluid Bed Processor Spring Assembly for Overpressure Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid bed processors face damage during internal explosions due to the lack of an effective mechanism to manage overpressure, which requires containment within the container while allowing movement to engage seal rings and clamp rings.
Innovation Solution
A movement mechanism featuring springs in the legs of the lower housing section that absorb and store kinetic energy from explosions, biasing the housing sections into sealing engagement and dissipating energy when pressure is relieved, allowing clamp rings to contain forces during an explosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If clamp rings are used to contain pressure during explosion, then pressure containment is improved, but housing damage occurs due to excessive movement
Solution Approach 1:
The patent applies beforehand cushioning by incorporating springs into the legs supporting the lower housing section. These springs are pre-positioned to absorb and dissipate the kinetic energy generated during an internal explosion, cushioning the impact before it reaches the housing sections and preventing damage while still allowing the clamp rings to engage and contain the pressure.
2Ease of operation
If clearance is provided between clamp rings and seal rings, then separation movement is enabled, but pressure containment is reduced
Solution Approach 1:
The patent applies dynamics by making the support legs dynamic through the incorporation of springs. The legs can move vertically to accommodate the engagement and disengagement of clamp rings while maintaining sealing contact. This dynamic capability allows the system to transition between operational states (separated for loading/unloading and engaged for pressure containment) without compromising either function.
3Stability of the object's composition
If housing sections are rigidly connected, then structural stability is improved, but movement for clamp ring engagement is prevented
Solution Approach 1:
The patent applies segmentation by dividing the support structure into separate modular components: the housing sections remain rigid for stability, while the legs are separate elements with spring mechanisms that provide the necessary movement. This segmentation allows each component to perform its specialized function - the housing maintains structural integrity while the legs enable the controlled movement required for clamp ring engagement and disengagement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Minimizes damage to the processor by effectively containing overpressure and restoring housing sections to their original positions after the explosion, ensuring safe operation and reduced structural damage.
Implementation Method 1
The springs form an energy absorbing assembly which absorbs and stores the kinetic energy from an internal explosion in the processor, and then dissipates the kinetic energy when the explosion pressure is relieved.
Implementation Method 2
The spring assembly normally biases the lower and middle housing sections into engagement with the upper housing section.

AI summary
An overpressure absorption mechanism is provided for a fluid bed processor. The mechanism includes spring assemblies mounted in the legs of the processor. The arms of the lower housing section extend into the legs and are supported on the springs. If an overpressure condition arises within the processor, the springs compress to allow movement between the housing sections to allow engagement of clamping rings which contain the over pressure condition.
