Description

聚烯烃双壁波纹管成套生产设备
技术领域
本实用新型涉及一种聚烯烃双壁波纹管成套生产设备。 
背景技术
现有的聚烯烃双壁波纹管成套生产设备，包括按工艺流程顺序依次设置的挤出机、挤出模具、管材成型机、冷却水槽、管材切割机和管材堆放机；所用挤出机为单螺杆挤出机，由于单螺杆挤出机输送能力较低，比流量较小，导致生产设备的产量低，相应的导致了产品的成本居高不下，没有市场竞争力。要想提高产量必须提高螺杆转速，转速的提高不但使能耗大大增加，同时也使机筒内的剪切热上升，对物料的剪切大，容易造成聚烯烃的高分子链断裂，致使管材的耐压能力降低。另外，做管材的原料除聚烯烃外，还添加少量回收料和适量的填充剂，但由于单螺杆挤出机的混炼效果差，导致管材不同部段的材质不均，造成刚度降低。也就是说，现有的聚烯烃双壁波纹管成套生产设备，是以牺牲产品的质量为代价，来换取产量的提高。 
实用新型内容
本实用新型要解决的技术问题是针对上述缺陷提供一种聚烯烃双壁波纹管成套生产设备，该设备产量高，能耗低。 
为了解决上述技术问题，本实用新型提供了一种如下结构的聚烯烃双壁波纹管成套生产设备，包括按工艺流程顺序依次设置的挤出机、挤出模具、管材成型机、冷却水槽、管材切割机、管材堆放机，其结构特点在于所述挤出机为双螺杆挤出机。 
所述双螺杆挤出机为平行双螺杆挤出机。 
所述双螺杆挤出机为锥形双螺杆挤出机。 
双螺杆挤出机的两根螺杆的相对旋转，在物料输送过程中，物料不产生倒流或滞流，具有强制输送的特点，不易产生局部积料、堵塞排气孔，螺杆啮合处对物料的剪切使物料的表层得到不断的更新，增进了排气效果；双螺杆挤出机由于两根螺杆在啮合处螺楞或螺槽的速度并不完全相同存在速度差，被螺纹带入啮合间隙的物料受到螺楞和螺槽间的挤压和研磨，使物料得到很好的混合和混炼；由于两根螺杆在啮合处螺楞或螺槽的速度并不完全相同，在相互擦离的过程中，可以相互剥离黏附在螺杆上的物料，使螺杆得到自洁；双螺杆挤出机螺杆加料段螺槽深同时受到两根螺杆的推力作用强制向前输送，物料输出量大而快，使得聚烯烃双壁波纹管成套生产设备产量大大提高。由于双螺杆挤出机具有两根螺杆，在转速不高的情形下，物料的挤出量比单螺杆挤出机大很多，因此对物料的剪切小，不会使聚烯烃的高分子链断裂，在提高产量的同时能保持管材具有较好的耐压能力。双螺杆挤出机混炼效果好，使得管材的材质比较均一，可以使管材具有较好的刚度。 
综上所述，本实用新型具有优点在于：结构简单，产出高 ，能耗低，所产的双壁波纹管耐压能力强、刚度好。 
附图说明
下面结合附图对本实用新型的具体实施方式作进一步的详细说明： 
图1是本实用新型一种结构形式的示意图。
具体实施方式
如图1所示的聚烯烃双壁波纹管成套生产设备，包括按工艺流程顺序即按图中箭头所示的方向依次设置的挤出机1、挤出模具2、管材成型机3、冷却水槽4、管材切割机5和管材堆放机6，所述挤出机1为双螺杆挤出机。上述的挤出模具2、管材成型机3、冷却水槽4、管材切割机5、管材堆放机6均为公知设备，双螺杆挤出机也为公知设备，例如可选用平行双螺杆挤出机或锥形双螺杆挤出机。 
本实用新型生产过程如下：配好的聚烯烃料被上料机送入到双螺杆挤出机1中被塑化、混炼后挤出进入挤出模具2，通过挤出模具挤出内外两层料坯，进入成型机3后，内层料坯紧贴在定径套外壁上，外层在负压下被吸附在成型模具的内壁上，在成型机3的成型和牵引作用下被送入到冷却水槽4中，通过设置在冷却水槽中的喷头冷却后进入管材切割机5中，管材切割机接到来自控制系统的信号后切割管材，切割后的管材进入堆放机6。
