Example Embodiment

[0021] The present invention will be described in detail below in conjunction with specific embodiments:

[0022] The plastic bottle recycling processing method of the present invention includes the following steps:

[0023] a. Sorting, sorting plastic bottles according to color and removing plastic bottles containing metal or sand. Use manual sorting or machine sorting. Single-color plastic bottles are selected according to the manufacturer's needs, which is convenient for storage and sale; plastic bottles containing hard objects such as metal or sand are removed to avoid damage to the machine and reduce impurities.

[0024] b. Crushing, shearing and crushing the sorted plastic bottles to obtain plastic bottle flakes. The size of the plastic bottle after being cut and broken is 8 mm to 14 mm. Compared with the traditional direct-cutting crushing method, the shearing crushing method is progressive crushing, with smaller resistance, lower vibration, lower noise, and faster cutting ...

Abstract

The invention discloses a plastic bottle recycling and processing method and aims to provide a plastic bottle recycling and processing method which is relatively high in production efficiency and relatively high in recycling quality. The plastic bottle recycling and processing method comprises the following steps: sorting plastic bottles; performing shearing type crushing on the sorted plastic bottles to obtain plastic bottle slices; heating and steaming the plastic bottle slices to remove viscidity of labels and viscidity of residual liquid; performing saline-alkali water flotation on the steamed plastic bottle slices, and filtering to remove impurities; horizontally and spirally stirring the impurities-removed plastic bottle slices and grinding and washing the plastic bottle slices through sieve holes to remove dark spots on the plastic bottle slices; upwards spirally stirring the dark-spot-removed plastic bottle slices and blowing air upwards from the two sides to remove labels in the plastic bottle slices; performing upward spiral stir-frying on the label-removed plastic bottle slices and blowing air from the bottom to heat and dry. The invention further provides a plastic bottle recycling and processing production line which is relatively high in production efficiency and relatively high in recycling quality.

Description

technical field [0001] The invention relates to a plastic bottle recycling processing method, and also relates to a production line used for the plastic bottle recycling processing method. Background technique [0002] Recycling of waste plastic bottles is a requirement of environmental protection. Plastic bottles with higher recycling value now mainly include mineral water bottles and carbonated beverage bottles. The main material of mineral water bottles and carbonated beverage bottles is PET (Polyethylene terephthalate, polyethylene terephthalate), also known as polyester resin. The material of the bottle cap is ABS (Acrylonitrile butadiene Styrene copolymers, acrylonitrile-butadiene-styrene copolymer), PS (Polystyrene, polystyrene), PE (polyethylene, polyethylene) or PP (Polypropylene, high polymer polymer) propylene). The ABS cover and PS cover are submersible covers, and the PE cover and PP cover are non-sinkable covers. [0003] In the process of recycling plastic...
