s1-4: the remainder after S1-3 screening is divided into a 3D three-dimensional object and a 2D flat object, and the 3D three-dimensional object and the 2D flat object respectively enter a 3D three-dimensional object manual sorting belt conveyor and a 2D manual sorting belt conveyor to be manually sorted, wherein the 3D three-dimensional object is manually sorted into PET bottles, hard plastics, nonferrous metals, glass and HDPE bottles, and the 2D flat object is manually sorted into paperboards, fabrics and plastics;
s1-5: and (4) classifying the materials separated in the steps, transferring PET bottles, HDPE bottles, glass and waste paper which need to be subjected to fine classification to a subsequent corresponding system for fine classification, transferring foams to a subsequent foam recovery system for packaging treatment, and directly selling the plastics.
When mixing recovery thing sorting system during operation, select out the great material of volume earlier, reduce the granularity that mixes the recovery thing, the magnet separator of so being convenient for adsorbs the iron, avoids major possession article to shelter from, can improve magnetic separation efficiency and success rate. Meanwhile, large articles are removed, the bouncing sieve can bounce and sieve the materials smoothly, the materials can be separated in the bouncing process by the aid of the bouncing sieve, the materials are in contact with the adhesion of the articles, the 2D flat objects and the 3D three-dimensional objects are separated, the bouncing performance of the 3D three-dimensional objects is larger than that of the 2D flat objects, so that the materials on the bouncing sieve can be directly divided into the 2D flat objects and the 3D three-dimensional objects, the materials are respectively transferred to the 2D flat object manual sorting belt conveyor and the 3D three-dimensional object manual sorting belt conveyor to be manually sorted again, and different types are sorted. 2D flat material and 3D solid are separately selected separately respectively, have avoided all article miscellaneous to be mixed and mixed, thereby avoided article to shelter from, can effectively improve and select separately the success rate, and can improve separation efficiency, improve the productivity greatly, for screening the spring sieve back direct separation, the success rate is higher, the article kind that staff need select on an artifical separation belt feeder is less, can reduce staff's visual fatigue, avoid the dazzling mistake, the separation work of being more convenient for goes on, also can reduce staff's intensity of labour.
In the mixed recyclable material sorting system, the roughly-sorted outspun materials are respectively cached in corresponding caching bins according to types, and then are transported out of the system by using transporting devices such as a turnover cage and the like; wherein large fabrics, plastics, iron, nonferrous metals and the like are directly boxed and transported to leave a factory for corresponding recovery treatment and are usually directly sold; and the rest PET bottles, HDPE bottles, paperboards, glass, foams and the like are respectively and correspondingly transported to a plastic bottle recovery system, a glass recovery system, a waste paper recovery system and a foam recovery system which are positioned at the downstream of the mixed recyclable material sorting system for fine separation and packaging treatment.
In one embodiment, since the content of each recyclate in the mixed recyclates is uncertain and not statistical, the workflow is fixed, namely: after the materials are fed, the materials are fed to a manual sorting belt conveyor to be directly manually sorted, built fabrics, paperboards, plastics, foams and the like in the materials are selected, then the materials are continuously transported forwards and enter a magnetic separator unit to be deironized, the iron in the mixture is selected and then is conveyed into a bouncing screen to be screened, the materials below the screen are low to recyclable materials, the materials are directly collected and transported to be buried or otherwise processed, the materials above the screen are bounced by the bouncing screen to separate 3D three-dimensional materials and 2D flat materials, then the materials are respectively sorted nondifferentially, because the manual sorting belt conveyor reaches the final end of a sorting system of the recyclable materials, the materials cannot be continuously moved forwards, the manual sorting personnel need to complete the nondifferential sorting of all the materials, the 3D three-dimensional materials are finally sorted into PET bottles, hard plastics, nonferrous metals, glass, HDPE bottles, 2D flat materials are sorted, Fabric, and plastic.
Preferably, the S2 step separately processes sorted PET and HDPE bottles sourced from the S1 gross sort and off-line recycle bin. Because the PET bottle and the HDPE bottle are different in material, value and application, the PET bottle and the HDPE bottle are divided into two types during recycling and further classified and recycled, and the utilization value of various bottles can be guaranteed to the maximum extent.
As shown in fig. 2, preferably, the PET bottle sorting comprises the following sub-steps:
s2 (1) -1: putting the PET bottle into a label removing machine for physical label removing; because the common PET bottle is usually used as a beverage bottle and the like, the outer part of the common PET bottle is usually wrapped with an outer label, sometimes even all the labels are wrapped, the recycling of the PET bottle is influenced, and the labels are not adhered to the bottle body, so that the labels can be removed by scratching the labels by a blade in the label removing machine, and the label removing machine is simple and convenient; the PET bottle after label removal is convenient for subsequent classification and recovery, and the subsequent classification of the PET bottle according to the color can not be influenced.
S2 (1) -2: conveying the PET bottles after label removal to a photoelectric separator unit through a chain conveyor for separation, and respectively separating transparent and light blue PET bottles and green PET bottles; before PET bottle sorting, programs are set in the photoelectric sorting machine unit, PET bottles with corresponding colors are respectively selected, and bottle sorting is realized.
S2 (1) -3: the remainder of the S2 (1) -2 is continuously forwarded to an AI intelligent robot and a manual sorting unit for further sorting, transparent and light blue PET bottles and green PET bottles which are not separated in the S2 (1) -2 are respectively sorted, and meanwhile, variegated PET bottles are separated; because the sorting of the photoelectric sorting machine unit can not reach the hundred percent of the precision, an AI intelligent robot and a manual sorting unit are matched behind the photoelectric sorting machine unit, so that the effective purification effect can be achieved, the missed sorting is continuously selected for the front target, and finally the mixed-color PET bottle is remained.
S2 (1) -4: and packaging the transparent and light blue PET bottles, the green PET bottles and the variegated PET bottles selected from the S2 (1) -2 and the S2 (1) -3 by a bottle packaging machine to form various package blocks, so that the transportation is facilitated.
As shown in fig. 2, preferably, HDPE bottle sorting comprises the following substeps:
s2 (2) -1: feeding HDPE bottles, conveying the HDPE bottles to a photoelectric separator unit through a chain conveyor for separation, and respectively separating pure white HDPE bottles and light-color HDPE bottles;
s2 (2) -2: the remainder of S2 (2) -1 is continuously forwarded to an AI intelligent robot and a manual sorting unit for further sorting, pure white HDPE bottles and light-color HDPE bottles which are not separated in S2 (2) -1 are respectively sorted, and meanwhile, variegated HDPE bottles are separated;
s2 (2) -3: pure white HDPE bottles separated from S2 (1) -1 and S2 (2) -2, light-color HDPE bottles and variegated HDPE bottles are packaged by a bottle packaging machine to form various package blocks, so that the transportation is facilitated.
Carry out the essence time-sharing to the HDPE bottle, although also there is the wrapping paper on the HDPE bottle body, but utilize the viscose to be attached on the bottle body mostly, the label can't be taken off in the realization of the label taking off machine of utilizing physics, need utilize chemical reagent sol back to take off the label, and the wrapping paper on the HDPE bottle usually is only partial parcel body, does not influence the colour of photoelectric separation machine unit to the HDPE bottle and distinguishes, consequently, when categorised the retrieval to the HDPE bottle, not pass through and take off the mark step, only classify it. Therefore, the HDPE bottles directly enter the photoelectric sorting machine unit after being loaded to be sorted according to colors, the pure-color HDPE bottles are selected firstly, the light-color HDPE bottles are selected, the AI intelligent robot and the manual sorting unit are used for purification and fine sorting, the remaining variegated HDPE bottles are separated finally, and then the sorted isolated HDPE bottle diameter bottle packing machines are sorted and packed into various packing blocks.
As shown in fig. 2, preferably, the photoelectric sorting unit includes a first photoelectric sorting machine and a second photoelectric sorting machine which are sequentially connected in series, each photoelectric sorting machine is respectively set with different modes corresponding to the color types of the bottles to be sorted, and the first photoelectric sorting machine is set with two modes: the first mode is as follows: only clear and light blue PET bottles, mode two were sorted out: only select pure white HDPE bottle, be provided with two kinds of modes on the second photoelectric sorting machine: the first mode is as follows: only green PET bottles were sorted, mode two: sorting only light-colored HDPE bottles; when PET bottles are sorted, the first photoelectric sorting machine and the second photoelectric sorting machine both select a first mode; when the HDPE bottle is sorted, the first photoelectric sorting machine and the second photoelectric sorting machine both select the mode two.
It should be noted that the first photoelectric classifier and the second photoelectric classifier can select either one of them to be in front and the other one to be in back. That is, when the system is arranged, the first photoelectric classifier may be provided at the front end, and the second photoelectric classifier may be provided at the front end.
Because PET bottles are generally classified into three categories when they are recycled: pure and light blue PET bottles, green PET bottles and variegated PET bottles, HDPE bottles are generally classified into three categories when recycled: pure white HDPE bottles, light-colored HDPE bottles and variegated HDPE bottles, so that two types of PET bottles or HDPE bottles are selected by only two photoelectric sorting machines, and the rest PET bottles or HDPE bottles are of the third type.
Thus, the plastic bottle concentration process in one embodiment is:
if the supplied materials are PET bottles, the supplied materials are firstly subjected to label removing by a label removing machine and then enter a first photoelectric sorting machine to select transparent and light blue PET bottles, then green PET bottles are selected by a second photoelectric sorting machine, then the obtained green PET bottles are purified by an AI intelligent robot and an artificial sorting unit, the transparent and light blue PET bottles and the green PET bottles which are not separated by the photoelectric sorting machine unit are selected, and finally the remained PET bottles are the variegated PET bottles.
If the supplied materials are HDPE bottles, the supplied materials directly enter a first photoelectric sorting machine to select pure white HDPE bottles, then light-color HDPE bottles are selected through a second photoelectric sorting machine, then the pure white HDPE bottles and the light-color HDPE bottles which are not separated from the photoelectric sorting machine unit are sorted through an AI intelligent robot and a manual sorting unit for purification, and finally the left pure white HDPE bottles and the light-color HDPE bottles are mixed-color HDPE bottles.
