This machine adopts the automated water circulation system, continuous feeding and washing. This system uses the structure specially designed to cause friction of PET bottles inside the machine, and uses the high-temperature chemical water to remove the labels, dirt, sands, glues, rubbers, metal and other impurities on the bottles surfaces. Through detection system, it is able to conduct automatic control over temperature and chemical supplement, to achieve comprehensive automatic control of production process, and guarantee bottle washing quality.
Supporting chemical water filtration system, using coarse filter, fine filter, sedimentation, separate impurities of chemical water and reuse, thus to prolong the service life of the chemical water.
The bottle Pre-washing unit has a significant impact on the PVC contents of the recycled flakes. High-temperature washing can make changes in the appearance of PVC bottles, making it easy to distinguish in the PET bottles and manual sorting become very
simple; meanwhile, the bottles cleaned can allow the automatic selection system with higher sorting efficiency.
The whole system inclueding the procedures: debaler, pre-washer, label remover, sorting, granulating, washing dewatering, second granulation for size reduction drying ect.
A typical PET bottle washing plant is consist of the following components:
* Belt conveyor: For waste material in feeding.
* Bale Breaker – opens the tight bales of PET bottles to loose bottles one by one.
* Trommel screen: big trommel could separate heavy stones, caps, sand or other small contamination down from these bottles go through it.
* Pre-washing: This machine has a big volume should work with hot water with high temperature. It mainly used for pre-washing the bottles before crushing and removes some contamination out. ( PVC bottles after go through the hot water may change color and could be sorted out further.)
* Label remover: For removing most percentage labels on the bottle body before crushing. This machine also have the function of pre-washing as well.
* Sorting belt: Sorting processed bottles again by manual to separate them by color ,type and sorting the dirties out before granulating.
* Metal Detector – detects metal contamination that may remain in the bottles
* Granulator/ Crusher: Wet crushing system.It used for material size reduction and pre-washing.
* Screw conveyor : For PET flakes transportion
* High speed Friction washer: High speed friction washing could achieve a good cleaning effects through the blades on the beating and spray. This machine is suitable for broken film and Plastic flakes washing.
* Single screw or double screw washing tank/ Screw washer: For flakes floating washing and conveying.
* Hot Washing Tank/ steam washer – hot washing process with alkaline (caustic) soda to remove glue and oil
* Horizontal dewatering machine( Dehydrator):This machine is mainly used for the cleaning of waste plastic after mechanical dewatering and drying, the spindle through high speed rotating threw the plastic and water to the screen, water releases by screen, while the plastic is from the outlet to be out of the machine enters into the next procedure. The machine has a good drying effect and high energy efficiency. The blade is made of high wear-resistant materials, can be replaced more conveniently.
* Second granulator (optional): For PET flakes size reduction to final size required.
* Zig-Zag label separator: For separate labels in the crushed flakes.
* Blower and transition silo: transportation to storage silo.
* Control cabinet: For control the whole system intensively.
