Embodiment 1

[0035] Such as figure 1 Shown in, the present invention discloses 1. a recovery process of PET bottle, it is characterized in that, comprises the following steps:

[0036] A. Feeding: Put the recycled PET bottles on the conveyor belt, and remove the packing belt and waste iron wire during the feeding process.

[0037] B. Screening: Remove plastic sheets, PVC bottles, labels, PE bottle caps, and stone impurities from the PET bottles conveyed in A in the screening area, leaving only white PET bottles; in this step, double screening by machine screening and manual screening The screening method mainly removes plastic sheets, labels, PE bottle caps, and stone impurities through machines; through artificial assistance, PVC bottles and PET plastic bottles with different colors are screened out.

[0038] C. Wet crushing: Put the white PET bottle screened in B into a wet crushing machine, crush the PET bottle into plastic fragments of different sizes, and transport the waste water to...

Abstract

The invention discloses a PET bottle recycling process, which comprises the following steps: A, feeding; B, screening; C, wet breaking, D, gravity rinsing; E, cleaning with hot alkaline; F, water washing; G, centrifugal dewatering; H, rinsing for three times; I, centrifugal dewatering; J, packaging. The recycling process provided by the invention is mainly used for recycling of white waste plastic bottles, the process is easy to operate and control, harmful gas and harmful pollutants are not generated during the recycling process, energy conservation and environment protection are achieved, and process is high in degree of automation, and high in efficiency. White plastic fragments obtained through the process are cleaned and rinsed through multiple processes, so that impurities such as glue on the plastic bottles can be removed well, and the obtained clean plastic fragments can be directly applied to the subsequent processing production, therefore, the cost is reduced and good economic benefits are achieved.

Description

technical field [0001] The invention belongs to the field of resource recycling, in particular to a plastic bottle recycling process, in particular to a white plastic bottle recycling process. Background technique [0002] With the progress and development of industrial technology, because of the good performance and low cost of plastic products, various plastic products play an important role in packaging in many fields. While plastic products bring convenience to people's lives, they also Tens of thousands of waste plastic waste are generated. The traditional method is to landfill and incinerate plastic products. However, the degradation cycle of ordinary plastic waste in the natural environment is more than one hundred years, and harmful Substances, therefore, landfilling is not a good way to dispose of plastic products; subsequently, incineration replaced landfilling, however, incineration can produce harmful gases and smoke, and these harmful substances also have an imp...
