Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for producing coal cakes for coking face inefficiencies in compression and solidification due to direct impact methods, which result in lateral material displacement and uneven stress on the molding box walls.
Innovation Solution
A device with a processing unit that moves both horizontally and vertically, featuring a stamp block that can be movably coupled to the impact element, allowing for controlled impulse transfer and reduced speed to minimize lateral displacement, with a stamping surface design that concentrates compression and adapts to different material properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If direct impact method is used to compact coal bed, then compaction speed is improved, but lateral material displacement increases and stress on molding box walls becomes uneven
Solution Approach 1:
The patent introduces a stamping block as an intermediary between the impact element and the coal bed. The impact element strikes the stamping block, which then transfers the impulse to the coal bed. This mediator allows the impact force to be distributed over a larger area and controlled duration, achieving effective compaction while minimizing lateral material displacement and reducing stress concentration on molding box walls.
2Productivity
If impact element strikes bulk material directly, then compaction efficiency is improved, but stress on adjacent side walls of mold box increases
Solution Approach 1:
The stamping block serves as a mediator that distributes the impact force from the impact element across a broader area of the coal bed. This distribution effect reduces the concentration of stress on adjacent side walls of the mold box while maintaining effective compaction efficiency through controlled impulse transfer.
3Manufacturing precision
If stamping surface of punch block is smaller than impact surface of impact element, then compaction is more concentrated, but material deflection perpendicular to impact direction increases
Solution Approach 1:
The patent applies local quality by designing the stamping surface of the punch block to be larger than or equal to the impact surface of the impact element. This configuration ensures that the impact force is distributed over a sufficient area, preventing material deflection perpendicular to the impact direction while maintaining concentrated compaction beneath the stamping block through the controlled impulse transfer mechanism.
