Technical Field
[0001] The utility model belongs to the technical field of garbage disposal, and in particular relates to a dry and wet garbage classification device. Background Art
[0002] Garbage is discarded items that have lost their use value and cannot be used. It is an important link in the material cycle and is solid or fluid material that is not needed or useful. In densely populated cities, garbage disposal is a headache. The common practice is to collect and send the collected garbage to landfills for disposal, or to incinerate it in incinerators. However, both of these methods will create environmental protection problems. Ending excessive consumption can further reduce the saturation of landfills. Garbage disposal in landfills will not only pollute groundwater and emit odors, but the area available for landfill in many cities is getting smaller and smaller. Therefore, it is necessary to sort and process the garbage. However, the existing garbage sorting and processing devices are simple in structure, and more solid garbage often remains in liquid garbage. Such mixed processing will result in poor results. In addition, the existing garbage dry-wet separation devices only carry out the next process flow after simple extrusion, which makes the solid-liquid separation efficiency low.
