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
The present invention relates to field of domestic garbage treatment, particularly relate to one way of life refuse breaking method for separating.
Background technology
In domestic garbage comprehensive treatment industry, various fragmentation and pneumatic separator kind more, but due to China's house refuse complicated component, classify special, cause various device processes poor effect, if any one disintegrating machine and separator directly apply in house refuse, all structural destruction can be produced because of the complexity of component of refuse to equipment.Problem faced by some are common limits the development of domestic garbage comprehensive treatment industry, as existed: in (1) oversize, bulk plastic is by manual sorting, and fritter plastics just directly carry out landfill; (2) landfill material is fluffy takies larger space; (3) plastics that go out of selection by winnowing are unclean; (4) problems such as Leachate site is difficult, contaminated environment.
Current domestic garbage comprehensive process pre-treating technology is enter material by grab bucket material loading mostly, enter sorting platform hand picking and go out the too large material of size, enter rotary screen screening again, screenings directly enters subsequent fermentation precipitation, and oversize directly carries out landfill.It is large to there is amount of landfill in such technique, the shortcoming of the wasting of resources of recoverable.
Summary of the invention
Based on the problem existing for above-mentioned prior art, the invention provides one way of life refuse breaking method for separating, ironware can be realized to house refuse and be separated, plastics are separated, and fabric is separated, the fragmentation of organic and inorganic matter, reduce the amount of landfill of rubbish, increase the resource of recoverable.
For solving the problems of the technologies described above, the invention provides one way of life refuse breaking method for separating, comprising the following steps:
Refuse collecting material hole is entered after house refuse computation weigh, apron feeder is delivered to by hydraulic grab, house refuse enters rotary screen through chain scraper conveyor again, super large piece article is sieved out, the oversize of rotary screen enters oversize gathering system: after selecting regenerant by manual sorting's platform and magnetic separation, and residue house refuse send landfill yard landfill;
The screenings of rotary screen is through magnetic separation, after selecting metal, leftover materials enter Domestic garbage crushing screening installation and carry out cracking and sorting discharging, material after cracking and sorting process is divided three classes: the screenings that particle diameter is less than 50mm, the plastics sub-elected, material that can not be broken, and wherein 50mm screenings enters screenings gathering system and enters subsequent technique; The plastics sub-elected enter plastics baling press; Material that can not be broken enters oversize gathering system, finally enters landfill yard.
Beneficial effect of the present invention is: coordinated by manual sorting's platform, magnetic separation, rotary screen and Domestic garbage crushing screening installation, and in process house refuse process, achieve ironware be separated, plastics are separated, and fabric is separated, the fragmentation of organic and inorganic matter.
