Clinker Cooler Profile Structure for Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coolers for hot bulk materials, such as cement clinker, have complex structures and large overall heights, leading to increased costs and inefficient use of space, necessitating a more compact design with optimized bearing forces.
Innovation Solution
A cooler with a stationary aeration base and movable conveyor units above, supported by a profile structure that absorbs forces, eliminating the need for additional frame structures and allowing for independent movement of conveyor units, thereby reducing overall size and enhancing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional frame structures with additional support elements are used, then the cooler has sufficient bearing capacity, but the overall height and device complexity increase
Solution Approach 1:
The profile structure combines multiple functions: it serves as both the support frame and the bearing surface for the aeration base. The aeration base is placed directly on the profile structure, eliminating the need for separate support elements and reducing overall structural complexity while maintaining bearing capacity.
Solution Approach 2:
The profile structure performs multiple functions simultaneously: it provides structural support, serves as a bearing surface for the aeration base, and defines the spatial arrangement of the cooler components. This multi-functionality reduces the number of separate components needed.
2Strength
If traditional frame structures with additional support elements are used, then the cooler has sufficient bearing capacity, but the overall height increases
Solution Approach 1:
By merging the support function and the aeration base function into a single integrated structure, the overall height is reduced. The aeration base sits directly on the profile structure without requiring additional vertical support elements.
3Stability of the object's composition
If conveying elements are fixed to a rigid frame, then the structure is stable, but the bearing forces are not optimized and the design is less compact
Solution Approach 1:
The conveying elements are designed to move dynamically along the profile structure rather than being fixed to a rigid frame. This allows the bearing forces to be optimized as the conveying elements can adapt their position and movement pattern, reducing unnecessary structural reinforcements.

Function Achieved in This Case
The compact design results in cost savings and efficient use of space, enabling effective cooling of bulk materials while maintaining optimized bearing forces, facilitating the movement of cement clinker from a rotary kiln to the end of the cooler.
Implementation Method 1
cooling gas flows through it
Implementation Method 2
cooling gas flows through passages through which cooling gas flows, for example by means of a fan, from below the aeration floor upwards through the aeration floor

AI summary
The invention relates to a cooler (10) for cooling bulk material, in particular cement clinker, comprising a stationary aeration floor (12) through which cooling gas can flow, and for receiving the bulk material, at least one conveyor unit (14) having conveying elements (16) arranged above the aeration floor (12), which can be moved back and forth in the conveying direction and against the conveying direction for the transportation of the bulk material, and a drive device (18) for driving the conveying elements (16). The cooler also comprises a profile structure (20), extending in the conveying direction, for receiving the aeration floor (12), and a bearing unit (22) for bearing the conveyor unit (14) on the profile structure (20), such that the conveyor unit (14) can be moved relative to the profile structure (20) in the conveying direction and against the conveying direction.
