Shock-Compression System for Inorganic Waste Landfill Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional test pieces are inadequate for reproducing the state of inorganic waste landfilling at a final disposal site, as they primarily focus on cement-based materials and fail to accurately simulate the conditions of inorganic waste disposal.
Innovation Solution
A system and method involving mixers, a cylindrical molding form, an air-press device, and ancillary equipment to produce and shock-compress materials, replicating the layering and consolidation of inorganic waste, including toxic and radioactive substances, to recreate the landfilling state, with the system adaptable for installation on a freight automobile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional mixing and molding methods are used for CSG material, then cement-based test pieces can be produced, but the state of inorganic waste landfilling at final disposal sites cannot be reproduced
Solution Approach 1:
The patent changes the compaction method parameter from conventional static compression to shock compression. This parameter change enables the test piece to reproduce the actual landfill state where waste is deposited and compacted in layers, improving the reproduction accuracy for inorganic waste materials while maintaining compatibility with existing molding infrastructure
Solution Approach 2:
The patent introduces a covering material layer as a preliminary action before and after banking material placement. This preliminary action replicates the actual landfill structure where covering layers protect and contain the waste, thereby improving the fidelity of reproducing the landfill state without complicating the overall process
2Ease of operation
If multiple equipment are disposed separately for mixing and compression operations, then each device can function independently, but work efficiency and material transfer convenience are reduced
Solution Approach 1:
The patent merges the mixer and air-press device into an integrated system where the mixer is positioned adjacent to the air-press device. This combining of equipment eliminates the need for intermediate material handling, improves operational convenience, and maintains functional independence of each component while reducing overall system complexity
3Productivity
If no storage space is provided for ancillary equipment, then the system occupies less space, but workflow efficiency and equipment accessibility are compromised
Solution Approach 1:
The patent adds a storage space dimension to the system by providing a dedicated area for ancillary equipment such as molding forms and tools. This dimensional addition improves workflow efficiency and equipment accessibility without significantly increasing the main operational footprint, as the storage space can be organized vertically or in unused corners of the work area
