Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Such as figure 1 The domestic garbage sorting system shown includes a quantitative feeding device, a magnetic separation device, a gravity gradient sorting device, a pendulum crushing device, an air separation device, a needle selection device 22 and a material conveying device.

[0031] The quantitative conveying device comprises a quantitative feeding device housing 2 . The top of the housing 2 of the quantitative feeding device is provided with a No. 1 feeding port 1 . The housing 2 of the quantitative feeding device is provided with No. 1 steel beam 3 and No. 2 steel beam 6 which are arranged adjacently and parallel to each other. No. 1 steel beam 3 and No. 2 steel beam 6 are respectively hinged with a No. 1 feeding roller boom 4 and No. 2 feeding roller boom 7. The No. 1 feed roller boom 4 can rotate relative to the No. 1 steel beam 3, an...

Abstract

Disclosed is a domestic waste crushing and sorting system. The system comprises a quantitative feeding device, a magnetic separation device (10), a gravity gradient sorting device (12), a pendulum-type crushing device, a wind separation device (29) and a needle separation device (22) and a material conveying device. The system has a compact structure, is easy to operate, is safe and reliable, and can sort urban domestic wastes into corrodible organic substances, combustible wastes, metals, glasses and light recyclable substances, thereby not only making full use of the urban domestic wastes but also having high environmental benefits and social benefits.

Description

technical field [0001] The invention relates to the field of garbage classification, in particular to a domestic garbage crushing and sorting system. Background technique [0002] According to statistics, in 2014, the annual volume of municipal solid waste in my country was about 191 million tons, and it was growing at an annual rate of 8%-10%. . At present, my country's municipal solid waste treatment methods mainly include sanitary landfill, composting, and incineration. Among them, incineration has become a more popular treatment method because it can greatly reduce the volume and weight of garbage, and can generate clean electricity. However, the composition of domestic garbage in our country is complex, and the volume of garbage is different. In particular, it contains a large amount of kitchen waste, and it is mostly placed in plastic bags, making the moisture content of domestic garbage mostly above 50%, resulting in difficulty in burning garbage and low efficiency. ...
