Trademarks, Film Air Separator
—Using the wind as a sieve, intelligently separating heavy and light substances, it precisely peels away label and film impurities.
Core positioning:This product is specifically designed for plastic bottle flake (PET/PE/PP, etc.) recycling and granulation lines.Dry physical sorting equipmentIt utilizesAerodynamic principlesThrough precisely controlled airflow, the crushed material is...Lightweight impurities with low density and large surface area—MainlyPlastic labels (OPP, PVC labels), residual film, paper scraps, dust--andHigh-density main bottle flakes or fragmentsHighly efficient separation is a key pretreatment device for ensuring the purity of recycled plastic particles and reducing downstream processing problems.
I. The Core Role of Air Classifiers in Recycling Granulation Lines
In the recycling of plastic bottle flakes, labels and films are the main lightweight pollutants, and their hazards and sorting difficulties lie in:
Affecting product quality:Labels mixed into the melt, causingRegenerated granules exhibit black spots, stringiness, and decreased strength.。
Damage to production equipment:The film easily gets tangled in the screw, and the carbonized label paper clogs the filter, increasing the frequency of downtime for cleaning.
Traditional cleaning methods are ineffective in removing:The label is tightly attached to the bottle, and cannot be completely separated by friction cleaning alone. Furthermore, wet processing consumes a lot of water and energy.
High-efficiency separation requirements:Need to beDry state, high throughputSeparating materials with similar physical states and sizes but different densities under certain conditions is technically challenging.
The value of an air separator lies in:Provide aHigh efficiency, energy saving, and zero water consumptionThe solution removes more than 90% of light impurities before the material enters the hot washing or melt extrusion process, greatly reducing the burden on subsequent processes.
II. Core Product Design and Technological Advantages
We adopt"Multi-level gradient air separation + intelligent wind speed control + high-efficiency circulating dust removal"The systematic design enables precise sorting.
1. Scientific design of the air separation chamber and airflow:
Stepped multi-stage sorting chamber:The material falls step by step under the influence of gravity, passing through...Multiple independent and controllable wind selection zonesEach wind speed is adjustable, allowing for the removal of impurities of different weights and shapes.Stepped precision rejectionThe sorting is more thorough.
Equilibrium flow field technology:Through uniqueHoneycomb air distribution panel or streamlined air duct designEnsure that the entire separation section is withinUniform and stable airflow speedIt has no dead angles and avoids the loss of good materials or the residue of impurities caused by local turbulence.
Adjustable angle deflector:Optimize the movement trajectory and residence time of materials in the airflow to enhance the separation effect.
2. Intelligent risk control and driving system:
Variable frequency closed-loop control system:The core wind turbine adoptsHigh-performance high-pressure centrifugal fan,Depend on
