Pivot-Mounted Rollers for Wet Concrete Block Edge Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing concrete blocks, such as the 'rumbling method' and hammer devices, impose high mechanical stress, are costly, and result in high dust emissions, limiting processing to only fully cured blocks and requiring complex apparatus setups, while also failing to address burrs effectively before coating.
Innovation Solution
A device with pivot-mounted processing means, such as rollers, that can process concrete blocks before full curing, reducing mechanical stress and dust emissions, allowing for continuous operation and integration into production lines, with cylindrical or conical rollers providing uniform pressure and efficient edge removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hammering tools are used to process concrete blocks, then edge processing is achieved, but mechanical stress is excessively high and concrete blocks are crushed
Solution Approach 1:
The patent replaces the hammering mechanism with a grinding mechanism. Instead of using hammering tools that impose high mechanical stress, the invention employs grinding elements that mechanically process the concrete block edges through controlled abrasion, thereby achieving edge processing without crushing the blocks.
Solution Approach 2:
The patent changes the mechanical action parameter from impact (hammering) to abrasion (grinding). This parameter change allows the processing to occur on still-soft concrete blocks without exceeding their strength limits, as grinding applies distributed pressure rather than concentrated impact forces.
2Adaptability or versatility
If hammer device is mounted to move in transport direction and transverse direction, then processing coverage is improved, but device complexity increases
Solution Approach 1:
The patent divides the processing function into multiple stationary grinding elements arranged in a row, each capable of processing blocks as they pass by. This segmentation eliminates the need for complex movement mechanisms while achieving comprehensive processing coverage through the distributed arrangement of simple grinding units.
Solution Approach 2:
Instead of making the processing device movable to follow the blocks, the invention inverts the approach by making the blocks move through a stationary array of processing elements. This inversion simplifies the device structure while maintaining processing effectiveness.
3Ease of operation
If processing is done in dry concrete area after drying chamber, then hammer device can be used, but dust emissions increase
Solution Approach 1:
The patent performs the edge processing in the wet concrete area, before the blocks enter the drying chamber. This preliminary action allows processing to occur when the concrete is still soft and less dusty, reducing dust emissions while maintaining processing feasibility through the use of grinding elements adapted for wet conditions.
4Strength
If already completely cured concrete blocks are processed, then high mechanical stress methods can be used, but processing time is delayed
Solution Approach 1:
The patent performs edge processing as a preliminary action during the wet concrete area, before the blocks are completely cured and before they enter the drying chamber. This timing allows processing to occur while the concrete is still soft and manageable, eliminating the waiting time that would otherwise be required for complete curing.
Applied Scientific Principles
