Abstract
本发明公开了一种可满足复杂废料塑化条件的螺杆,包括依次相连的挤出段、压缩段和进料段,所述压缩段的锥度为2°12′55″~3°12′55″且压缩段的压缩比为3.2。本发明的优点是:合理的回收废料中的可回收资源,并再次利用,减少环境的污染。该废料中包括容易塑化的薄膜和性能差、不容易塑化的PE、PP等塑料及橡胶。
Description
技术领域
本发明涉及到一种螺杆。
背景技术
现在的政府提倡环保,比如农业中使用的薄膜、工业用的橡胶及一些性能差不容易塑化的可回收的塑料。这些东西混合在一起之后,使得很多普通螺杆无法将其合理的塑化并挤出,因此不能很好的回收利用。
发明内容
本发明所要解决的技术问题是:提供一种螺杆,该螺杆能够满足废料的塑化条件,该废料包括薄膜、PE、PP、橡胶等。
为解决上述技术问题,本发明采用的技术方案为:一种螺杆,包括依次相连的挤出段、压缩段和进料段,所述压缩段的锥度为2°12′55″~3°12′55″且压缩段的压缩比为3.2。
本发明的有益效果是:上述螺杆能够使得废料在压缩段中完全塑化,使得能被螺杆挤出,并合理的回收废料中的可回收资源。
附图说明
图1是本发明螺杆结构图。
图中:1、挤出段,2、压缩段,3、进料段。
具体实施方式
下面结合附图,详细描述本发明的具体实施方案。
如图1所示,本发明所述的螺杆,包括依次相连的挤出段1、压缩段2和进料段3,其中挤出段1、压缩段2和进料段3的长度比为26∶15∶33,所述压缩段2的锥度为2°12′55″~3°12′55″且压缩段2的压缩比为3.2。
经过实践证明,上述螺杆能够将复杂的废料塑化并挤出,从而合理的回收废料中的可回收资源,并再次利用,减少环境的污染。该废料中包括容易塑化的薄膜和性能差、不容易塑化的PE、PP等塑料及橡胶。由于该废料的复杂性,普通螺杆无法将其完全塑化及挤出,但是本发明的螺杆可以。
Claims (1)
1.螺杆,包括依次相连的挤出段、压缩段和进料段,其特征在于:所述压缩段的锥度为2°12′55″~3°12′55″且压缩段的压缩比为3.2。
