Abstract
The present invention relates to a method for recycling plastic from garbage and granulating, which uses robot feeding, bag broken screening, magnetic separation, winnowing and artificial picking to comprehensively treat plastic in the garbage, greatly improves the cleanliness of the screened plastics, and provides a good quality assurance for the subsequent granulation. A clean plastic granulation raw material is fed into a cutting compaction cylinder for further crushing and compacting, and then fed into an extruder. The plastic is plasticized in the extruder and water is fully discharged. The plastic is then fed into an automatic hydraulic screen exchanger to filter out non-plastic impurities, fed into a horizontal pelletizing die for cutting, and cooled for molding through circulating cooling water to obtain plastic granules, which are dehydrated, and sent in a warehouse for storage by wind. The finished plastic granules are obtained. The method of the invention is convenient to produce and high in operability, effective solves the problem of environment pollution and ecological harm from garbage and achieves cyclic utilization and green environmental protection.
Description
Technical field
The invention belongs to rubbish cycling and reutilization field, especially a kind of method that from rubbish, reclaims the plastics granulation.
Background technology
Traditional waste disposal method, composting process, landfill method and burning method have all seriously influenced the utilization again of plastics resources, and the plastics ratio is about 10% in the Chinese city component of refuse, but the rate of recovery of waste or used plastics is extremely low.Landfill method in underground, is difficult to degraded with the long-term landfill of waste plastics; Composting process can only become soil and fertilizer with organic matter in the rubbish, and plastics can not effectively utilize therein, and influences fertilizer efficiency; Burning method has not only been blocked the approach of plastics circulations, and burns extremely toxic substances such as afterwards producing dioxin, causes secondary pollution.Therefore, existing technology of garbage disposal all can not be carried out the rational and effective utilization to plastics, and plastics can't reenter in the productive life, cause the huge waste of resource.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of method that plastics are granulated that reclaims from rubbish is provided, this method is convenient for production, strong operability, effectively solve garbage environment pollution, the ecological problem of harm, realized recycling, environmental protection.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of method that from rubbish, reclaims the plastics granulation, its method step is as follows:
, with rubbish by material loading robot material loading and carry out chaff interference letter sorting;
⑵, rubbish is sent into broken bag rotary screen extension set carry out broken bag screening;
⑶, the rubbish after the broken bag screening is sent into permanent magnetic separator carry out magnetic separation;
⑷, the rubbish after the magnetic separation is sent into negative pressure winnowing machine and malleation winnowing machine respectively carry out selection by winnowing and handle;
⑸, the rubbish after the selection by winnowing is carried out the artificial hand selection, obtain plastic products;
⑹, the plastic products behind the artificial hand selection are sent into crusher in crushing become the 40mm particle diameter, the engaging friction cleaning machine fully cleans again, send into again potcher through the mixer stirring and washing, leave standstill, obtain clean plastics granulation raw material;
⑺, clean plastics granulation raw material is delivered to the compacting that further is broken of cutting compacting tube, send into extruder again, plastics are also fully discharged moisture by plasticizing in extruder, after sending into the impurity that the automatic hydraulic net-changing device filters out not plasticization again, enter horizontal pelletizing die cuts,, obtain plastic grain after dehydration simultaneously by the cooling circulating water cooling and shaping, deliver to feed bin through wind and store, obtain the plastic grain finished product.
And described broken bag rotary screen extension set sieve diameter is 80mm and 40mm.
Advantage of the present invention and beneficial effect are:
This method that reclaims the plastics granulation from rubbish successively adopts robot material loading, broken bag screening, magnetic separation, selection by winnowing and artificial hand selection that the plastics in the rubbish are carried out integrated treatment, improved the cleanliness factor of screening plastics greatly, for follow-up granulation has improved good quality assurance.The inventive method is convenient for production, strong operability, effectively solve garbage environment pollution, the ecological problem of harm, realized recycling, environmental protection.
The specific embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of method that from rubbish, reclaims the plastics granulation, its method step is as follows:
, with rubbish by material loading robot material loading and carry out chaff interference letter sorting, the material loading robot is controlled by remote computer;
⑵, rubbish is sent into broken bag rotary screen extension set carry out broken bag screening; Broken bag rotary screen extension set sieve diameter is 80mm and 40mm, and sieve diameter can be adjusted; Establish retractable blade in the broken bag rotary screen extension set, only scratch plastic bag surface, do not destroy hard thing, for example battery etc.;
⑶, the rubbish after the broken bag screening is sent into permanent magnetic separator carry out magnetic separation; Magnetic separation sub-elects metal and is brought together take-away, enters other treatment systems after the screenings magnetic separation, and oversize enters selection by winnowing;
⑷, the rubbish after the magnetic separation is sent into negative pressure winnowing machine and malleation winnowing machine respectively carry out selection by winnowing and handle; Selection by winnowing sub-elects light plastic, and all the other enter other treatment systems;
⑸, the rubbish after the selection by winnowing is carried out the artificial hand selection, the artificial hand selection goes out impurity in the plastics with above-mentioned selection by winnowing, paper etc. for example, and hand picking obtains plastic products;
⑹, the plastic products behind the artificial hand selection are sent into crusher in crushing become the 40mm particle diameter to clean with convenient, the engaging friction cleaning machine fully cleans to remove most of silt impurity again, send into again potcher through the mixer stirring and washing, leave standstill, heavy things such as silt fully separate with plastics, plastic foil floats on the water surface, obtains clean plastics granulation raw material;
⑺, clean plastics granulation raw material is delivered to the compacting that further is broken of cutting compacting tube, send into extruder again, plastics are also fully discharged moisture by plasticizing in extruder, after sending into the impurity that the automatic hydraulic net-changing device filters out not plasticization again, enter horizontal pelletizing die cuts,, obtain plastic grain after dehydration simultaneously by the cooling circulating water cooling and shaping, deliver to feed bin through wind and store, obtain the plastic grain finished product.
