Description
Technical Field
[0001] The invention belongs to the technical field of waste plastic recycling devices, and in particular relates to a solid waste plastic packaging material recycling device and method. Background Art
[0002] With the rapid development of social economy and the continuous improvement of people's living standards, plastic packaging materials are used more and more widely in daily life and industrial production. In order to save costs and reduce pollution to the environment, it is generally necessary to recycle difficult-to-degrade plastics. After the plastics are recycled, a crusher is needed to crush the plastics. After crushing, the plastics enter the plastic extruder for melting and extrusion, and then enter the mold for remolding to achieve recycling.
[0003] Problems with existing technologies: However, the existing solid waste plastic packaging material recycling devices on the market have a series of problems that need to be solved. During the feeding process, dust leakage is common. Some simpler hoppers are directly connected to the crushing equipment. When the material is poured into the hopper, due to the lack of effective dust prevention measures, the dust generated at the moment of pouring the material will be discharged into the air in an unorganized manner. This not only makes the production workshop full of dust, greatly reducing the air quality of the workshop, but also may cause pollution to the surrounding environment.
[0004] In addition, a large amount of dust will also be generated in the unloading process after crushing. This dust flies in the workshop, which, on the one hand, seriously pollutes the environment of the production workshop and makes the cleaning and maintenance of the workshop much more difficult; on the other hand, long-term exposure to such an environment will seriously threaten the health of operators and easily cause occupational diseases such as respiratory diseases. At the same time, too much dust mixed in the plastic particles will also affect the purity of the plastic particles, which will have a negative impact on the subsequent processing of the plastic particles and reduce the quality and performance of the product.
