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

螺杆
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。
