AI Technical Summary

Technical Problem

Existing technologies struggle to effectively separate polypropylene and butyl rubber materials in medical infusion bottles, resulting in low-quality recycled materials. Traditional separation equipment is unable to efficiently screen materials based on their properties.

Method used

A medical infusion bottle rubber and plastic screening and separation device was designed, including a feeding component, a shredding component, a kneading component, a primary separation component, and a secondary separation component. The device separates materials by utilizing the differences in their physical properties through steps such as shredding, kneading, and airflow separation.

Benefits of technology

This technology enables efficient separation of polypropylene and butyl rubber, improving separation accuracy and purity, and ensuring the quality of recycled materials.

Abstract

本发明公开了一种医用输液瓶橡塑筛选分离设备,包括上料组件、撕碎组件、揉搓组件、一级分离组件及二级分离组件。上料组件用于将输液瓶调整为横置姿态并输入撕碎组件;撕碎组件用于对输液瓶进行撕碎处理,使塑料瓶体破碎并将橡胶瓶塞挤出。揉搓组件用于将破碎后的物料进行揉搓,使脆性的聚丙烯材料进一步碾碎;一级分离组件转动安装于揉搓组件外围,其上开设的筛分孔将碾碎后的塑料颗粒筛分下落,而未被碾碎的橡胶块则被输送至下游外排。二级分离组件设置于一级分离组件下方,通过托举气流与水平气流,利用密度与颗粒大小的差异,将细小聚丙烯颗粒与粘连的丁基橡胶颗粒进行分离。本申请实现了对输液瓶的高效分离,显著提升了回收品质。
