摘　　要：提出一种热风熔融的方法对废旧塑料进行再生利用,其特点是:废旧回收塑料直接进行热风加热熔融后通过螺杆挤出造粒,没有粉碎过程,无噪音、粉尘飞扬;热风熔融的温度容易控制,防止过热降解;热风循环无废水排出,余热全部利用。在理论分析的基础上,设计构建了试验样机并进行试验研究。This paper proposed a hot air melting method for the reuse of waste plastics.With this method,the waste plas‐tics was melted directly in the hot air and then extruded and palletized.There is no crashing needed in the whole process,generating no noise and dust accordingly.The temperature of hot air can be controlled easily,and therefore the degrada‐tion caused by overheating can be avoided.The waste heat can be reused through hot air recycling.Based the theoretical analysis,an experimental prototype was designed and manufactured,following by conducting a validation experiment.
