Vibrating Calciner Vessel Retention and Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the angle of a vibrating calciner vessel to align with the dynamic repose of granular materials and draining the vessel are limited, as they do not account for varying material properties over time or efficient material flow, and common clamping mechanisms fail to withstand high temperatures and mechanical stresses.
Innovation Solution
The use of spring-loaded clamps applying opposing forces to circular ring segments around the vessel allows for adjustable alignment with the dynamic angle of repose and enables 160-180 degree rotation for unconfined granular material flow, with a drain tube positioned for efficient discharge, utilizing materials that withstand high temperatures and mechanical stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If common clamping mechanisms are used to hold the vessel, then the device is simple to manufacture, but they fail to withstand high temperatures and mechanical stresses
Solution Approach 1:
The clamping mechanism is divided into multiple independent spring-loaded clamps distributed around the vessel perimeter, each capable of withstanding high temperatures and mechanical stresses independently. This segmentation allows the system to maintain strength under extreme conditions while keeping individual clamp components relatively simple and manufacturable.
Solution Approach 2:
The clamping force parameter is dynamically adjusted through spring-loaded mechanisms that can withstand high temperatures. The spring constant and pre-load forces are specifically selected to maintain adequate clamping pressure on the vessel under thermal expansion and mechanical stress conditions, resolving the contradiction between strength requirements and manufacturing simplicity.
2Adaptability or versatility
If the vessel angle is fixed during fabrication, then manufacturing is simpler, but adjustment is needed when material properties change over time
Solution Approach 1:
The vessel angle is made dynamically adjustable through the spring-loaded clamp system. By releasing and repositioning the clamps, the vessel can be rotated to different angles to match varying dynamic repose angles of different granular materials. This dynamic capability provides adaptability to changing material properties while keeping the adjustment mechanism relatively simple, involving only the release and repositioning of existing clamps rather than complex mechanical adjustment devices.
3Productivity
If the vessel rotates 160-180 degrees for drainage, then granular material flows unconfined, but the clamping mechanism must withstand significant mechanical stress
Solution Approach 1:
The spring-loaded clamps provide counterbalancing forces that withstand the mechanical stresses generated during 160-180 degree vessel rotation for drainage. The springs are pre-loaded to compensate for the weight of the vessel and granular material, maintaining adequate clamping force throughout the rotation range and enabling efficient material flow without compromising structural integrity.
Solution Approach 2:
The clamps are pre-positioned and pre-loaded to anticipate the mechanical stresses that will occur during vessel rotation for drainage. This preliminary preparation ensures that when the vessel is rotated 160-180 degrees, the clamping mechanism is already configured to withstand the significant mechanical stresses, enabling efficient material drainage without failure.
4Reliability
If opposing clamps are used to retain the vessel, then the vessel can be secured, but the clamping force must equal 5 times the vessel and material weight
Solution Approach 1:
Multiple spring-loaded clamps are combined and distributed around the vessel perimeter, each applying a portion of the total required clamping force. This merging of multiple smaller clamping forces achieves the total force requirement (5 times vessel and material weight) while distributing the mechanical stress across multiple components, improving reliability through redundancy and reducing the force burden on any single clamp.

AI summary
A vibrating calciner includes circular ring segments surrounding a vessel and clamps adjustable to apply pressure to the ring segments. A plurality of vessel dams are positioned within the vessel and spaced apart along a central longitudinal axis. The vessel is rotatably positionable about the central longitudinal axis within the circular ring segments such that inner edges of the of vessel dams may be positioned at an angle substantially equal to the dynamic angle of repose of a granular material. The vessel is held in position by the clamps which contact the ring segments. In embodiments, the vessel may be rotated to drain material through a drain tube positioned opposite the vessel dams.
