Sorting and separation system for long-strip articles in urban domestic garbage

Abstract

The invention discloses a sorting and separation system for long-strip articles in urban domestic garbage, which comprises a two-sectional drum screen, a double-shaft shearing crusher, an air-blower, a collection device for fabrics and a collection device for plastics; the two-sectional drum screen comprises a fixed frame and a drum screen arranged on the fixed frame, and the drum screen comprises an entrance section of the drum screen and an exit section of the drum screen; a plurality of bag-breaking cutters are arranged on the inner wall of the entrance section of the drum screen; and a plurality long-strip article hanging devices are arranged in the exit section of the drum screen, a long-strip article collection device is arranged in the exit section of the drum screen, a rear end of the long-strip article collection device extends out of the exit section of the drum screen and extends to a feeding part on the upper end of the double-shaft shearing crusher, the air-blower is arranged on the discharging part of the double-shaft shearing crusher, and the collection device for fabrics and the collection device for plastics are arranged in the lower part of the double-shaft shearing crusher. According to the system, long-strip articles in garbage can be effectively selected for separation, and the system has reliable selection and high accuracy of separation.

Description

Technical field [0001] The invention relates to the field of urban domestic waste treatment, in particular to a sorting and separating device for large long strips of urban domestic waste, in particular to an automatic, mechanized and intelligent sorting device for separating fabrics and plastics. technical background [0002] With the rapid development of the country's economy, the amount of urban domestic waste generated has increased sharply, and the problem of waste disposal is imminent. At present, waste disposal in my country mainly adopts landfill method, composting method and incineration method. Landfills are prone to produce landfill gas rich in CH4, which can cause explosions and also produce a large amount of landfill leachate, which contains heavy metals, toxic and harmful organic chemical pollutants, and a large number of viral pathogens. In the composting method, waste classification is not fine, and plastic, iron, glass and other residues in the raw materials for...

AI Technical Summary

Problems solved by technology

[0003] ① The sorting efficiency of fabrics with high calorific value is very low, and most sorting processes do not consider the sorting of fabrics;

[0004] ②The direct incineration of fabrics and plastics will cause secondary pollution, and there is no reliable method for the separation of fabrics and plastics
