Embodiment Construction

[0016] A kind of plastic bottle recovery method of the present invention, comprises

[0017] Step 1, washing and rolling the recovered plastic bottles, and cutting the rolled plastic bottles into pieces;

[0018] Step 2, steaming the cut plastic bottle;

[0019] Step 3, putting the cut plastic bottle into a melting extruder, and melting the plastic in the melting extruder;

[0020] Step 4, put the melted plastic into the screw extruder after cooling.

[0021] In the step 2, the cooking temperature is 80-90°C.

[0022] In the step 4, the melted plastic is cooled in a cooling tank at a cooling temperature of 20-35 degrees.

[0023] In the step 4, the screw speed of the screw extruder is 200-400 rpm.

[0024] The invention can conveniently and efficiently separate and recycle plastic bottles, effectively improves the purity of reclaimed plastics, has simple method, public welfare and environmental protection, and improves economic benefits.

[0025] The above-described embod...

Abstract

The invention discloses a method for recycling plastic bottles. The method for recycling the plastic bottles comprises the steps that 1, the recycled plastic bottles after being cleaned are spread, the plastic bottles after being spread are cut; 2, the plastic bottles after cutting are cooked; 3, the plastic bottles after cutting are put into a melt extruder, and the plastic bottles are melted inthe melt extruder; and 4, the plastic bottles after being melted are cooled, and then are put into a screw extruder. According to the method for recycling the plastic bottles, the plastic bottles canbe separated and recycled conveniently and efficiently, the purity of the recycled plastics is effectively improved, the method is simple, public welfare and environmental protection are achieved, andthe economic benefit is improved.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a method for recycling plastic bottles. Background technique [0002] Plastic bottles with high 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, and the material of the bottle cap is ABS or PP. The ABS cap and PS cap are submerged caps, and PE caps And the PP cover is an unsinkable water cover. [0003] The recycling of waste plastic bottles is a requirement of environmental protection. In the process of recycling plastic bottles, in order to improve the purity of plastic bottles, not only labels, glue and beverage residues must be removed, but also bottle caps must be separated. In the traditional mineral water bottle recycling technology, due to the crude processing equipment and rough processing methods, not only the production efficiency is low, but also the qua...
