Movable Distributor Plate and Web for Fluidizing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluidizing apparatuses face limitations in emptying speed and efficiency due to the formation of a process gas curtain at the discharge opening, which restricts the discharge of particulate material and reduces emptying speed.
Innovation Solution
Incorporating a web at the material outlet surface and a movable distributor plate that can be swiveled or displaced to create a fluid connection between the distributor and fluidization chambers, preventing the process gas curtain and allowing for unobstructed discharge of treated material, assisted by auxiliary gas if needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the distributor plate is positioned above the discharge opening in the prior art, then the fluidization chamber can be sealed from the distributor chamber, but a process gas curtain forms at the discharge opening that restricts material discharge and reduces emptying speed
Solution Approach 1:
The distributor plate is made movable relative to the fluidization unit, allowing it to be positioned in different locations. In the emptying position, the distributor plate is arranged on the web such that a fluid connection is created between the material outlet and the fluidization chamber, enabling unobstructed material discharge. This dynamic positioning resolves the contradiction by allowing the plate to be in different positions for different operational needs.
Solution Approach 2:
A web is introduced as an intermediary structure in the distributor chamber that extends at least partially in the circumferential direction. The web prevents process gas from flowing around the distributor plate and forming a restrictive curtain, while still allowing the distributor plate to be positioned on it for creating fluid connections. The web acts as a mediator that enables both sealing and unobstructed discharge.
2Speed
If the distributor plate is moved to create a fluid connection for rapid emptying, then material discharge speed increases, but process gas may flow around the distributor plate forming a curtain that restricts discharge
Solution Approach 1:
The web serves as an intermediary structure that the distributor plate is positioned on during emptying operations. The web extends in the circumferential direction and prevents process gas from flowing around the distributor plate to form a restrictive curtain, while still allowing the plate to be positioned to create the necessary fluid connection for rapid material discharge.
Solution Approach 2:
The web is arranged specifically in the region of the material outlet surface and extends at least partially in the circumferential direction, providing localized prevention of gas curtain formation exactly where it would most restrict discharge. This local structural feature enables rapid emptying without the harmful gas curtain effect.

Function Achieved in This Case
This configuration enhances the emptying speed and efficiency of particulate material from the fluidizing apparatus by preventing gas curtains and ensuring effective material discharge without contamination, while maintaining fluidization effectiveness.
Implementation Method 1
a process gas flowing from the fluid inlet through the perforated distributor plate to the fluid outlet and fluidizing the material in the fluidization chamber
