Domestic waste is discharged into bag breaker bale broken on weighing unit, the rubbish of dispersion is transported to screening machine after elementary drying machine drying, classify by the particle size of article, enter divisional processing system: particle diameter large article is classified by artificial hand selection, plastics, rubber enter cutting machine cutting, paper, woodwork enter cutting mill and pulverize, category of glass goods enter disintegrating machine and pulverize, metallic article enters magnetic separator and is separated by magnetic metal, all sorted rubbish enters corresponding collection box, waits pending; The article that particle diameter is less enter in corresponding winnowing machine after the screening of secondary screening machine, the kitchen waste compost process that selection by winnowing goes out, metal, sandstone enter magnetic separator and are separated by magnetic metal, and the flammable lightweight things such as paper, plastics, textile wait for that after pulverizer pulverizing, drying machine drying entering rotary kiln burns.
Because the operation principles such as the drying machine in system, screening machine, cutting machine, disintegrating machine, pulverizer, winnowing machine, magnetic separator all belong to techniques well known, and improvement of the present utility model does not lie in the said equipment, therefore repeat no more respective structure and operation principle.
Further, the top distribution spray equipment of described bag breaker inside, two sides arrange conical tooth to inwall, and inwall is fixed with axle between both sides, axle are arranged the thin tooth of gear shape.
Rubbish enters bag breaker, bale broken and spray course synchronization: refuse bag is bored after tooth or the thin tooth of gear type tear, and rubbish scatter, and the spray equipment of bag breaker inner tip continues to spray fungicidal wash downwards, plays the effect of control dust, sterilizing.
Further, described treatment system B comprises at least one winnowing machine.Winnowing machine quantity is preferably two, winnowing machine A and winnowing machine B; Described winnowing machine A and winnowing machine B is in parallel.
Because the operation principle of winnowing machine requires that article particle diameter is close, according to article gravity, heavy thing, lightweight thing effectively could be separated, so through the sorting of secondary screening machine, according to particle size range by article delivery in the winnowing machine of correspondence.In native system, the article of particle diameter 30-200mm enter in winnowing machine A, and the article that particle diameter is less than 30mm enter in winnowing machine B.In treatment system B, the function of winnowing machine is identical, is only configured according to the scope of article particle diameter and the running parameter of winnowing machine, so the arrangement mode of pneumatic separation device is in parallel, quantity adjusts according to actual conditions.
Further, connect with pipeline between described equipment, in pipeline, be provided with conveyer belt.
Be the routine techniques in this area due to pipeline and conveyer belt, and improvement of the present utility model does not lie in this, and those skilled in the art can draw setting and the course of work of pipeline and conveyer belt by basic general knowledge yet, therefore it not illustrated in detail.
Further, ventilation unit, dust arrester is also comprised.
Because the operation principles such as the ventilation unit in system, dust arrester all belong to techniques well known, and improvement of the present utility model does not lie in the said equipment, therefore repeats no more respective structure and operation principle.
Further, described drying machine B is preferably pneumatic drier, and drying machine B bottom sets into gas port, and drying machine B top sets out gas port.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) refuse classification control water content, making to enter the rubbish that cement rotary kiln burns is the small particle diameter combustible that water content is lower, has not only ensured the stability of burning but also the calorific value improving burning, thus has reduced the use of postcombustion, economize energy, reduces costs; Meanwhile, the generation controlling the pernicious gases such as bioxin is beneficial to, clean environment firendly.
(2) system layout is reasonable, farthest improves the recycling of all kinds of rubbish.
