Underwater garbage separator

Abstract

The invention discloses an underwater garbage separator, and relates to a garbage treatment technology. The underwater garbage separator comprises a main separation tank accessing treatment water, a collecting screw, feeding screw devices, and a shifting wheel capable of pushing and shifting garbage along the water flowing direction; the garbage falls into the main separation tank from the upper side of the main separation tank, and is separated according to specific gravity; the garbage with high specific gravity sinks and is conveyed out of the main separation tank through the collecting screw and a feeding screw device arranged close to the front end of the main separation tank; the garbage of which the specific gravity is same as that of water is suspended in water and is conveyed out of the main separation tank through the collecting screw and a feeding screw device arranged close to the rear end of the main separation tank; and the garbage of which the specific gravity is lower than that of water is floated on the water surface and conveyed out of the main separation tank through water flow, the shifting wheel and a conveyor belt arranged at the tail end of the main separation tank. The invention has the advantages that: the underwater garbage separator is particularly suitable for treating mixed domestic garbage; water is utilized to suppress dust and remove odor, the odor condition is radically changed, and the working environment for sanitation workers is fundamentally improved; and labor is saved and efficiency is high.

Description

technical field [0001] The invention relates to garbage treatment technology, in particular to a water separation device for garbage, which is suitable for a water treatment system for garbage. Background technique [0002] The garbage produced in life is called domestic garbage. Household garbage is piled up in residential areas, causing dust to fly, foul smell, sewage overflowing, and occupying a lot of land. At present, there are mainly three methods at home and abroad to deal with domestic waste: one is landfill; the other is combustion to generate electricity; the third is fermentation to produce combustible gas and fertilizer. Landfilling domestic waste is bulky and requires a large amount of land resources. It will not rot for 50 years and cause secondary pollution; burning power generation requires a large investment and releases toxic gases such as "dioxin"; the fermentation process takes a long time, and organic and inorganic things are difficult to separate. ...

AI Technical Summary

Problems solved by technology

Due to the dry crushing and sorting of garbage, the working environment is very dusty and smelly, and the working environment of the sanitation personnel is very harsh, and the waste plastic film bags accounting for about 5% of the garbage components cannot be sorted out for recycling.

[0007] Fourth, if garbage is sorted manually, the sorted waste plastics and metals are too dirty and need to be cleaned before they can be recycled, and the cleaned water is useless to be disposed of in time, which wastes water resources and causes re-pollution
