Abstract

本发明公开了一种橡胶挤出过滤机低温升型螺杆,由4头螺纹的螺杆加料段(1)、2头螺纹的输送段(2)和4头螺纹的定量段(3)组成,所述螺杆中心设有冷却水道(4)。本发明一种橡胶挤出过滤机低温升型螺杆,通过螺杆结构的改变,减低了胶料在挤出过程中产生的发热量,解决了大尺寸滤胶机用螺杆挤出胶料温升过高问题。

Description

橡胶挤出过滤机低温升型螺杆
技术领域
本发明涉及一种橡胶挤出过滤机低温升型螺杆。
背景技术
现有技术中,一次炼胶法是近年来新兴的橡胶炼胶新工艺,Φ450大规格的橡胶滤胶机是配合这种新的工艺方法而研制的新装备,在这种装备中的螺杆是技术关键,其构造对挤出胶料产生温升影响极大,在新的炼胶工艺中对滤胶机挤出胶料的产量,温度都有着严格的要求,这几项指标是常规构形螺杆完全达不到的,目前国内外均没有此规格的螺杆型滤胶机。
发明内容
本发明的目的是提供一种通过螺杆结构的改变,减低了胶料在挤出过程中产生的发热量,解决了大尺寸滤胶机用螺杆挤出胶料温升过高问题的橡胶挤出过滤机低温升型螺杆。
本发明为实现上述目的所采用的技术方案是:一种橡胶挤出过滤机低温升型螺杆,由4头螺纹的螺杆加料段(1)、2头螺纹的输送段(2)和4头螺纹的定量段(3)组成,所述螺杆中心设有冷却水道(4)。
所述冷却水道(4)在螺杆中心单孔进水,在螺杆周边多孔回水。
所述螺杆的长径比为1:3.5。
本发明一种橡胶挤出过滤机低温升型螺杆,通过螺杆结构的改变,减低了胶料在挤出过程中产生的发热量,解决了大尺寸滤胶机用螺杆挤出胶料温升过高问题。
附图说明
图1是本发明一种橡胶挤出过滤机低温升型螺杆的结构示意图。
图中:1、螺杆加料段;2、输送段;3、定量段;4、冷却水道。
具体实施方式
如图1所示,橡胶挤出过滤机低温升型螺杆,由4头螺纹的螺杆加料段1、2头螺纹的输送段2和4头螺纹的定量段3组成,螺杆中心设有冷却水道4,冷却水道4在螺杆中心单孔进水,在螺杆周边多孔回水,螺杆的长径比采用1:3.5,本发明改变了常规螺杆的螺纹结构,变化螺杆加料段的螺纹头数,把宽胶片切成窄条以降低胶料的温度,改变了螺杆的长径比,缩短输送段螺纹的长度减少输送距离产生的热量,增加定量段的螺纹头数再次把大块胶料切成窄料,用螺棱冷却胶料,降低胶料的温度,另外设计了新型的冷却水道,通过增冷却水的加冷却面积解决了胶料温升过高的问题。
