Overview

Plastic cleaning line is a general term for plastic cleaning, and is also often called waste plastic cleaning line equipment. The main purpose is to clean and recycle plastic environmental protection equipment. Plastic cleaning lines are mainly divided into two categories according to materials, one is soft plastic cleaning line equipment, and the other is hard plastic cleaning line equipment.
Soft materials include agricultural films, films, shade nets, fishing nets, PP woven bags, plastic bags, cement bags, etc., while hard materials usually include plastic housings for home appliances, plastic bottles, plastic buckets, plastic safety helmets, and computer housings. , TV plastic casings, plastic tables and stools, plastic pipes, etc. These soft and hard waste plastics can be recycled and processed, which not only saves resources but also protects the environment and increases economic value, which is of great significance.



Plastic cleaning process

There are differences in the process of processing waste plastic bottles and processing plastic films. Usually, they have different names. The processing of plastic bottles is usually called plastic bottle cleaning line, daily miscellaneous plastic crushing and cleaning line, and waste HDPE/PET bottle crushing. Cleaning line, etc.; for film processing, there are waste PE film cleaning line, waste PP woven bag cleaning line, ton bag crushing cleaning line and so on. The main process flow is as follows:
Waste PE film recycling and cleaning line process:
Feeding conveyor belt - uniform feeding - shredder with water to shred into bundles or loose woven bags, and pre-washing at the same time - screw washer 1 - conveying and cleaning - pre-washing machine - removing sediment and possible small stones Such foreign matter - screw cleaner 2 (transport and clean) - rinse sedimentation tank 1 (clean material, remove sediment and impurities) - crusher (pulverize and clean with water) - screw cleaner 3 (transport and clean) - horizontal Type friction cleaning machine 1 (cleaning materials, removing sediment and impurities) — rinsing sedimentation tank 2 further (cleaning materials, removing impurities) — horizontal friction cleaning machine 2 (cleaning materials, removing sediment and impurities) — centrifugal dehydrator ( Material dehydration) - hot air drying system (further drying) - bagging system - control electric box
Waste HDPE bottle recycling cleaning line process:
Bale opening machine (break up the compacted and packed PET bottles) - disc sorting machine (remove stones, small pieces of metal and falling bottle caps that may be contained) - manual selection platform (manually select PET bottles with different colors)-- --Metal detector (to detect the metal that may be contained in the material)-shredder (with water to break the HDPE bottle)-pre-washer (remove part of the sediment and the remaining liquid in the bottle, rub and rub the label to make it fall off)- ---Rinse sedimentation tank 1 (clean the bottle flakes, remove part of the sediment and impurities, protect the cutter of the pulverizer) - Crusher (with water to crush HDPE bottle flakes) - Spiral washing machine (transport and clean) - Rinse sedimentation tank 2 ( Wash bottle flakes, remove part of sediment and impurities) - centrifugal dehydrator (wash and dry HDPE bottle flakes) - de-labeling system (remove possible remaining labels) - bagging system - control electric box
Waste PP woven bag recycling cleaning line process:
Feeding conveyor belt (uniform feeding) - Shredder (shredding into bundles or loose woven bags with water, and pre-washing at the same time) - Spiral cleaner 1 (conveying and cleaning) - Pre-washing machine (removing part of the sediment and Foreign objects such as small stones that may exist)—spiral cleaning machine 2 (conveying and cleaning)—rinsing sedimentation tank 1 (cleaning materials, removing sediment and impurities)—horizontal friction cleaning machine 1 (high-speed scrubbing material)—rinsing sedimentation tank 2 (cleaning materials, removing sediment and impurities)----horizontal friction cleaning machine 2 (cleaning materials, removing sediment and impurities)-squeezing dryer and feeding system (squeezing materials)----hot air drying System (further drying material) - bagging system - control electric box
Waste PET bottle recycling cleaning line process:
Bale opening machine (break up the compacted and packed PET bottles) - disc sorting machine (remove stones, small pieces of metal and falling bottle caps that may be contained) - manual selection platform (optional, manual selection of PET bottles with different colors) )—metal detector (to detect the metal that may be contained in the material)—prewasher (to remove part of the sediment and the remaining liquid in the bottle, rub and rub the label to make it fall off)—crusher 1 (including feeding device, with water Crushing PET bottles) - Spiral washer 1 (conveying and cleaning) - Crusher 2 (with water to further crush PET bottle flakes to smaller size) - Spiral washer 2 (transporting and cleaning) - Centrifugal dehydrator 1 (washing and drying PET bottle flakes) - Z-type sorting system 1 (remove some labels) - high temperature cooking pot (clean PET bottles at high temperature, clean the oil and glue of bottle flakes) - rinse sedimentation tank (determine the number of equipment according to production requirements, remove bottle caps and labels, washing PET bottle flakes) - centrifugal dehydrator 2 (washing and drying PET bottle flakes) - Z-type sorting system 2 (removing possible remaining labels) - bagging system - control electric box
