Abstract

The invention discloses a cleaning process and a production line of PET (polyethylene terephthalate) bottle sheets. The cleaning process comprises the following steps of unpacking PET bottles, carrying out primary impurity removing by utilizing a whole bottle pre-cleaning device, removing labels from the PET bottles by utilizing a label removing device, removing heterochromous bottles and the bottles which are not made of PET materials by utilizing a sorting device, carrying out manual sorting by using a manual sorting platform, crushing by utilizing a crushing device, carrying out thermal cleaning by utilizing a thermal boiling boiler, neutralizing by utilizing a neutralizing tank, rinsing by utilizing a rinsing device, carrying out spin drying, drying by utilizing a drying cylinder, mixing, weighing and packaging, thus finishing the cleaning. According to the cleaning process, in full consideration of problem that too many impurities and pollutants exist in recycled PET bottles, various devices in a production process are adaptively transformed to be fit for the cleaning of the PET bottle sheets; the bottle sheets produced by utilizing the cleaning process and the production line can completely meet subsequent production and processing requirements, and the quality of the bottle sheets is improved; by utilizing a steam recycling system and the continuous spin-drying and drying operations, the energy utilization ratio can be greatly improved, the subsequent production and processing costs are lowered, and the cleaning process and the production line have wide social generalization significances.

Description

technical field

[0001] The invention relates to the field of cleaning PET bottle flakes, in particular to a PET bottle flake cleaning process and a production line thereof. Background technique

[0002] As we all know, in recent years, with the surge of the global population, the consumption of various plastic bottles has also increased significantly. Among them, due to the stable and excellent chemical properties of PET and good physical properties, the consumption of PET bottles has increased sharply worldwide. Facing the rapidly changing waste PET bottles, the waste PET bottle recycling industry urgently needs to promote the industrialization, scale and mechanization of waste PET bottle recycling. Because the material of the body of the bottle is different from that of the label attached to the bottle and the bottle cap --- the bottle body is usually PET, and the label is made of PVC, PE, PP and other materials, which caused problems in the recycling process. increase i...
