Embodiment Construction
[0016] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0017] A method for reclaiming plastic pellets from garbage, the method steps are as follows:
[0018] ⑴. The garbage is loaded through the feeding robot and the interference is sorted. The feeding robot is controlled by a remote computer;
[0019] ⑵. Send the garbage to the bag-breaking drum screening machine for bag-breaking screening; the diameter of the sieve hole of the bag-breaking drum screening machine is 80mm and 40mm, and the diameter of the screen hole can be adjusted; The surface of the plastic bag does not damage hard objects, such as batteries;
[0020] ⑶. Send the broken bags and sieved garbage to the permanent magnet magnetic separator for magnetic separation; the metals selected by magnetic separation are collected together...

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 [0001] The invention belongs to the field of garbage recycling and reuse, in particular to a method for recovering plastic pellets from garbage. Background technique [0002] Traditional garbage disposal methods, composting, landfill and incineration have seriously affected the reuse of plastic resources. The proportion of plastic in China's urban garbage is about 10%, but the recycling rate of waste plastic is extremely low. The landfill method will bury waste plastics in the ground for a long time, which is difficult to degrade; the composting method can only turn the organic matter in the garbage into soil fertilizer, and the plastic cannot be effectively used in it, and it will affect the fertilizer efficiency; the incineration method not only blocks the recycling of plastics, Moreover, highly toxic substances such as dioxins are produced after incineration, causing secondary pollution. Therefore, none of the existing waste treatment technologies can mak...
