Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional rotary calciners and vibrating bed equipment for processing granular materials at high temperatures require expensive mechanical components and complex setups, which increase costs and maintenance needs, while also limiting flexibility in processing due to fixed vessel diameters.
Innovation Solution
A method involving a circularly shaped vessel that induces a cascading motion through cross-axis vibration, eliminating the need for rotating components and allowing for a thinner, less expensive vessel design with adjustable cross-sections, supported by legs and featuring a drainage system to maintain efficient material flow and heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional rotary calciners are used to heat granular materials, then high temperature processing is achieved, but expensive mechanical components and complex setups are required
Solution Approach 1:
The patent applies mechanical vibration to the vessel containing granular material to induce cascading motion and enhance heat transfer. The vibration replaces complex rotating mechanical components with a simpler vibrated vessel design, maintaining high temperature processing capability while reducing mechanical complexity
Solution Approach 2:
The invention substitutes the traditional rotary calciner mechanical rotation system with a vibrated vessel system. Instead of using expensive rotating shells, steel tires, trunnion rollers, and ring gears, the patent uses a stationary or vibrated vessel where material motion is achieved through vibration-induced cascading rather than mechanical rotation
2Temperature
If traditional rotary calciners are used, then granular material is heated effectively, but costly mechanical parts such as steel tires and trunnion rollers are required
Solution Approach 1:
The patent replaces expensive, durable mechanical components (steel tires, trunnion rollers) with a simpler vibrated vessel system that uses less expensive materials. The vessel can be made from conventional materials rather than expensive heat-resistant alloys required for rotating calciners, significantly reducing manufacturing cost
Solution Approach 2:
The invention extracts and eliminates the expensive mechanical rotation system (steel tires, trunnion rollers, ring gears) from the heating process. The heating function is maintained through a simplified vibrated vessel design that separates the heating function from the complex mechanical transport mechanism
3Strength
If rotary calciners with fixed diameters are used, then structural integrity is maintained, but flexibility in processing conditions is limited
Solution Approach 1:
The patent introduces dynamic adjustability to the vessel system, allowing modification of vessel geometry, vibration parameters, and cross-sectional area. This enables the same basic vessel structure to adapt to different processing conditions and material types, providing flexibility without compromising structural integrity
Solution Approach 2:
The vessel is designed with modular or adjustable components that can be reconfigured for different processing requirements. The cross-sectional area can be varied along the length of the vessel, and the vessel can be segmented into zones with different characteristics, allowing optimization for specific processing conditions while maintaining overall structural strength

Function Achieved in This Case
This approach reduces the cost and complexity of equipment by eliminating costly mechanical parts and enabling more efficient heat transfer and material processing without rotating components, while allowing for varied processing conditions through adjustable vessel geometry.
Implementation Method 1
a method of heating of granular material at high temperature within a vessel which is vibrated by 'cross axis' vibration perpendicular to the long axis of the vessel to induce a circular motion of the granular material
Implementation Method 2
the granular material is tumbled in a circular cascading motion
Implementation Method 3
the granular material is tumbled in a circular cascading motion... continually exposes material to the radiant heat from the cylindrical tube heated by the furnace
Implementation Method 4
indirectly heating of granular solids is in rotary calciners... The exterior of the cylindrical tube is indirectly heated by the furnace

AI summary
A machine for the heating of granular material at high temperature, wherein a vessel is divided into compartments by vessel dams and vibrated in a direction perpendicular or ‘Cross Axis’ to the vessel longitudinal axis. The vessel is vibrated by counter rotating rotary vibrators to create a “Cross Axis” vibration causing a circular cascading movement of the granular material within the vessel. The vessel is surrounded by a furnace heated by electric power or a combustible gas.
