Mobile Waste Compaction with Vacuum and Air Pressure Sealing

The patent employs a pneumatic system with a compressor, vacuum pump, and distributed air outlets to create controlled pressure zones within the container. This pneumatic mechanism efficiently compacts waste by sequentially applying compression and vacuum forces, achieving high compaction ratios while maintaining manageable system complexity through modular pneumatic components.

The system dynamically changes pressure parameters within the container by alternating between positive pressure (compression phase) and negative pressure (vacuum phase). This parameter variation enables progressive waste compaction, transforming the waste from loose to densely packed state through controlled pressure cycling, thereby significantly improving compaction efficiency.

The pneumatic compaction system applies distributed pressure through multiple air outlets positioned at different heights and locations within the container. This enables uniform compression of waste throughout the volume, maximizing the amount of waste that can be stored in the available space while minimizing empty voids, thereby improving both collection capacity and space utilization.

By cycling through compression and vacuum phases, the system continuously optimizes waste density within the container. This parameter change approach ensures that the container volume is fully utilized with minimally compressed waste during collection, then progressively compacted during disposal phases, reducing the frequency of emptying and improving resource efficiency.

The pneumatic system serves multiple functions: it compresses waste during the compression phase, extracts air and moisture during the vacuum phase, and can be used for both initial waste loading and final compaction. This multi-functionality eliminates the need for separate mechanical compression devices, reducing overall system complexity while maintaining high compaction efficiency.

The system uses the compressed air and vacuum cycles to automatically perform both compaction and air extraction functions without requiring separate mechanical actuators or complex control systems. The pneumatic pressure differences themselves drive the compaction process, making the system self-sufficient and reducing the need for additional active compression mechanisms.

The system employs periodic cycles alternating between vacuum extraction and compressed air injection phases. During the vacuum phase, air and moisture are removed from waste; during the compression phase, compressed air forces waste into a denser configuration. This periodic action achieves superior volume reduction compared to vacuum alone, while the cyclic nature allows energy recovery and efficient operation.

The patent combines vacuum extraction and compressed air compression into a single integrated pneumatic system. By merging these two functions into one system that operates in alternating phases, the achievement high compaction efficiency through synergistic effect: vacuum removes air pockets and moisture, while compression forces waste into dense packing, together achieving greater volume reduction than either method alone.
