Description

超净级可交联聚乙烯绝缘料生产装置
(一)技术领域
本实用新型属高压电缆绝缘料技术领域，特别涉及超净级可交联聚乙烯绝缘料生产装置。 
(二)背景技术
国内现有的可交联聚乙烯电缆绝缘料产品依据的是行业标准JB/T10437-2004，其中规定的电线电缆用可交联聚乙烯绝缘料的最高等级是35kv，国内也少有能生产超净级或耐更高压电缆绝缘料的厂家。 
随着电缆行业的发展，和110kv级、220kv级高压电缆的需求，我国每年需要进口大量的超净级电缆绝缘料。突破传统设备和生产工艺的瓶颈，寻求新的可交联聚乙烯绝缘料生产工艺，已成为电缆料行业的当务之急。 
制约产品耐压等级的主要因素是杂质，聚乙烯、抗氧剂、交联剂原料本身就含有大量的杂质，生产车间空气中也含有大量杂质和尘埃，这都是影响产品洁净度的因素。 
(三)发明内容
本实用新型的目的是提供一种实现将聚乙烯、抗氧剂中的杂质在线过滤的超净级可交联聚乙烯绝缘料生产装置。 
本实用新型采用的技术方案：利用设备组合的方式，由双螺杆挤出机、主混炼机、单螺杆挤出机组成三阶机组，其中在聚乙烯、抗氧剂计量加料之后、主混炼机(8)之前设有双螺杆挤出机(5)和高目数滤网及换网器(6)，将聚乙烯、抗氧剂中的杂质在线过滤。 
高目数滤网及换网器(6)的滤网网片为80～500目滤网组合而成。 
交联剂融化后经过的液体过滤网(3.1)，目数为80～400，可以滤去杂质。 
动态计量后的聚乙烯(LDPE)、抗氧剂在双螺杆挤出机中熔融、经高目数滤网及换网器过滤、真空下料，然后进入主混炼机，并与液体过滤后的交联剂充分混合，再经真空下料进入单螺杆挤出机，通过挤出模头造粒。 
(四)附图说明
图1是本实用新型的生产工艺流程图。 
图2是本实用新型的设备组合结构示意图。

(五)具体实施方式
超净级可交联聚乙烯绝缘料生产装置，由双螺杆挤出机(5)、主混炼机(8)、单螺杆挤出机(10)组成三阶机组，其特征是在聚乙烯、抗氧剂计量加料之后、主混炼机(8)之前设有双螺杆挤出机(5)和高目数滤网及换网器(6)，将聚乙烯、抗氧剂中的杂质在线过滤。 
聚乙烯(LDPE)(1)通过粒料动态计量称(1.1)，然后落入入料螺杆(4)； 
抗氧剂(2)通过粉料动态计量称(2.1)，经粉料传送螺杆(2.2)落入入料螺杆(4)； 
入料螺杆将聚乙烯(LDPE)、抗氧剂连续送入双螺杆挤出机(5)； 
聚乙烯和抗氧剂在双螺杆挤出机(5)中充分熔融、混合，经过高目数滤网及换网器(6)过滤，滤去杂质，在真空下料腔(7)排出水汽和粉末后落入主混炼机(8)； 
交联剂(3)融化后经过液体过滤网(3.1)滤去杂质，进入液体动态计量称(3.2)，动态计量后经注射泵及保温软管(3.3)、注射枪头(3.4)进入主混炼机(8)后端； 
熔融混合的聚乙烯(LDPE)、抗氧剂在主混炼机中进一步熔融混合，并与交联剂充分混合后，经真空下料腔(9)排出水汽、粉末，落入单螺杆挤出机(10)； 
单螺杆挤出机将物料挤出，通过挤出模头(11)、切粒及粒料处理(12)，使粒料冷却、干燥、包装后成为超净级可交联聚乙烯绝缘料成品。
