Problems solved by technology
However, in the existing technology, the processing system for polyethylene waste is not perfect. Most polyethylene waste is still landfilled and degraded. The treatment is time-consuming and laborious, and cannot be recycled. The utilization rate of resources is low, and if there is any waste, it cannot be degraded. The polyethylene waste will cause irreversible damage to the ecological environment

The invention discloses a polyethylene preparation system. The system comprises a crushing mechanism used for crushing polyethylene waste materials, a grinding mechanism used for grinding the crushedmaterials, a dissolving mechanism used for dissolving the ground materials and a purifying mechanism. The dissolving mechanism comprises a dissolving chamber and a stirring device arranged in the dissolving chamber. The dissolving chamber comprises an inner shell and an outer shell, and a heating space is arranged between the inner shell and the outer shell. The polyethylene waste materials can berecycled, landfill treatment on the polyethylene waste materials is omitted, waste resources are sufficiently utilized, the resource utilization rate is high, the treatment cost is low, the phenomenon that a large amount of labor is input for landfill treatment is not needed, the labor input is reduced, and time and labor are saved.
Description
technical field [0001] The invention belongs to the technical field of polyethylene processing, and in particular relates to a polyethylene preparation system. Background technique [0002] With the acceleration of people's life rhythm, social life is developing towards convenience and sanitation. In order to meet this demand, polyethylene packaging materials such as disposable foam plastic lunch boxes and plastic bags have frequently entered people's daily life. However, in the existing technology, the processing system for polyethylene waste is not perfect. Most polyethylene waste is still landfilled and degraded. The treatment is time-consuming and laborious, and cannot be recycled. The utilization rate of resources is low, and if there is any waste, it cannot be degraded. Polyethylene waste will cause irreversible damage to the ecological environment. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a p...
