Waste Film Dry Washing Line Description:
At present, the traditional cleaning technology of waste plastics is mostly used in plastic recycling industry. The cleaning medium is water or water and detergent. According to the variety of waste plastic film pollution, the specific cleaning methods are different. The cleaning of agricultural film and packaging materials includes removal of oil cleaning, high speed friction, cold washing, drying and other processes. The cleaning of containers for toxic drugs includes neutralization, disinfection, solution cleaning, high speed friction, cold washing, drying and so on.
Water cleaning technology is a more mature technology widely used in China at present. The purity of the recycled particles is high, which can be used as the raw material of high quality plastic products. But the high running cost caused by repeated crushing and cleaning is the main shortcoming of the technology. Moreover, the large amount of waste water produced during the cleaning process causes two pollution to the environment and the cost of subsequent treatment is also very high.
Film Dry Washing technology has become a research direction of waste plastics recycling industry. Film Dry Washing technology does not use water as a medium, generally use air as a cleaning medium, so no waste water is produced, two pollution is greatly reduced, and water resources are saved at the same time. In the Film Dry Washing technology, the impurities in waste films can be removed and the purity of the regenerated particles can be improved by combining the cleaning and separation of impurities.
Main advantages compared with traditional washing:
The waste plastic dry-washing machine has improved the quality of products and the output of materials. As the recovered material is dry, the energy required for extrusion is reduced. The cost per ton of dry washing is 30% lower than the cost of conventional washing.
Equipment maintenance also saves cost. Because the impurity separation is very clean, the damaged parts such as screw, barrel and filter of the subsequent pelletizer/granulator can be effectively protected. No bubbles were generated during the processing, and the replacement time of the screen filter was prolonged. For screw and barrel, their service life is also extended to two times than original ones.
