The present invention for the technical scheme that solves the technical problem that exists in the known technology and take is: a kind of method for refining-sorting domestic garbage may further comprise the steps: a, rubbish is transported to carries out the artificial separation first time on the first artificial separation conveyer; B, the rubbish that will pass through artificial separation for the first time are transported in the rotary screen and sieve; C, will pass through the screenings that rotary screen sieves out and be conveyed into container, will pass through oversize after the cylinder screening and be conveyed into winnowing machine and carry out selection by winnowing; D, will pass through the light materials that the winnowing machine selection by winnowing goes out and after homocline is handled, send into the near infrared light extension set, to carrying out artificial separation second time through the surplus materials after the winnowing machine sorting, the rubbish that will pass through after the artificial separation second time is conveyed into container; E, will pass through sorting thing that the near infrared light extension set sub-elects and send into hopper and prepare to carry out subsequent treatment, residue is conveyed into container.
The present invention can also adopt following technical measures
Above-mentioned method for refining-sorting domestic garbage is characterized in: behind the said step a, rubbish is carried out the magnetic force sorting through magnetic grader handle.
Above-mentioned method for refining-sorting domestic garbage is characterized in: before the said step c, oversize is carried out the magnetic force sorting through magnetic grader handle.
Advantage and good effect that the present invention has are: the letter sorting workman is few, and the efficiency of separation is high; System is simple to operate, in the control room, carries out Long-distance Control, and automaticity is high; Operating cost is low, and economic benefit is considerable; Select the feed purity height, can reach 99%; Light optional equipment flexible operation can be selected the adjustment of material at any time.

Fig. 1 uses device structure sketch map of the present invention.
Among the figure: 1,2,6,8,10, conveyer, 3, magnetic separator, 4, the first artificial separation conveyer, 5, rotary screen; 7,15, reversible discharge conveyor, 9, magnetic separator, 11, winnowing machine; 12, material homogenizer, 13, the near infrared light extension set, 14, the second artificial separation conveyer.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of method for refining-sorting domestic garbage of the present invention:
Garbage truck with the direct discharging of rubbish to apron conveyor; Apron conveyor self has brokenly the bag homogenizing device, and house refuse is carried out coarse crushing, and the rubbish after the fragmentation is promoted to magnetic separator through conveyer; The house refuse of selecting the magnetic metal gets into first manual work and presorts choosing; This letter sorting workman in house refuse big glass, fabric etc. sort out and be thrown into centralized collection in the letter sorting platform container down respectively, the house refuse of presorting after the choosing gets into the rotary screen screening, and a bag cutter is housed brokenly in the rotary screen; Can be with the broken bag of big bagged garbage; Be mainly organic matter and dirt in the screenings of rotary screen, through conveyor delivery to discharge terminal, centralized collection to composting plant or sanitary filling field landfill.The oversize of rotary screen is promoted to magnetic separator by belt conveyor, carries out magnetic separation once more, and the oversize of selecting metal is delivered to air separation units by belt conveyor, through selection by winnowing the light materials in the oversize is sorted out, like plastics, paper, leaf etc.These materials are through getting into the near infrared light extension set after the material homogenizer homocline, according to the sorting requirement, can set according to the color of material, material etc., and equipment separates material automatically as required, and the material purity that sub-elects can reach 99%.Residue after selection by winnowing residue and light divide is through after sorting workman's selection, by transporting outward landfill after conveyor delivery to the discharge terminal centralized collection or burning a burning.
See also Fig. 1; Use equipment of the present invention, the output of conveyer 1 is above the input of conveyer 2, and magnetic separator 3 is above the output of conveyer 2; The output of conveyer 2 is above the input of the first artificial separation conveyer 4; The output of the first artificial separation conveyer 4 stretches into the input of rotary screen 5, and conveyer 6 joins with the screenings outlet of rotary screen in the bottom of rotary screen; The middle part of reversible discharge conveyor 7 below the output of conveyer 6 and with conveyer 6 vertical placements, the output of reversible discharge conveyor 7, input below is placed a container respectively.The oversize outlet of rotary screen 5 is above the input of conveyer 8; Magnetic separator 9 is above the output of conveyer 8; The output of conveyer 8 is above the input of conveyer 10, and the output of conveyer 10 links to each other with the pipeline of winnowing machine 11, and the light materials outlet of winnowing machine 11 links to each other with material homogenizer 12; The output of material homogenizer 12 is above the input of near infrared light extension set 13; Near infrared light extension set 13 is provided with two outlets, and one is the light materials outlet, and one is the surplus materials outlet; The surplus materials outlet is positioned at the output top of the second artificial separation conveyer 14; The output of conveyer 10 above the input of the second artificial separation conveyer 14, the middle part of reversible discharge conveyor 15 below the output of the second artificial separation conveyer 14 and with conveyer 15 vertical placements, the output of reversible discharge conveyor 15, input below is placed a container respectively.
