Abstract

The invention discloses a crushing and sorting method of domestic garbage and belongs to the field of domestic garbage treatment. The crushing and sorting method comprises the following steps: the domestic garbage is measured and weighed, then enters a garbage collecting pit, is lifted to a plate type feeder by a hydraulic crab and then enters a roller sieve by a chain-plate conveyor so as to sieve out ultra-large articles; the oversize articles enter an oversize article collecting system; after recoverable articles are separated out by an artificial sorting platform and magnetic separation, the remaining domestic garbage is conveyed to a landfill site for land filling; metals in undersize articles are recovered by second magnetic separation, and then the remaining materials enter the crushing and sorting equipment of the domestic garbage to be subjected to crushing and sorting treatment, wherein the treated materials are sorted into three types: undersize articles with the particle diameter being less than 50mm, sorted plastics and uncrushable materials, the undersize articles with the particle diameter being less than 50mm enter an undersize article collecting system to be processed by the following process, the sorted plastics enter a plastic packaging machine, and the uncrushable materials enter the oversize article collecting system and finally enter the landfill site. The crushing and sorting method disclosed by the invention has the advantages that ironware separation, plastic separation, fabric separation and crushing of organic and inorganic matter are realized.

Description

technical field [0001] The invention relates to the field of domestic waste treatment, in particular to a crushing and sorting method for domestic waste. Background technique [0002] In the domestic waste comprehensive treatment industry, there are many kinds of crushing and winnowing equipment. However, due to the complex composition and special classification of domestic waste in our country, the treatment effect of various equipment is not good. If any kind of crusher and sorting machine is directly used For domestic waste, structural damage to equipment will occur due to the complexity of the waste components. Some common problems limit the development of the domestic waste comprehensive treatment industry, such as: (1) large pieces of plastic in the sieve are manually sorted, and small pieces of plastic are directly landfilled; (2) landfill materials are fluffy Occupies a large space; (3) The plastics selected by the wind are not clean; (4) The leachate is difficult t...
