剖分式同向平行双螺杆挤出机一、前言近年来,随着聚合物改性材料的不断发展,其对混炼设备的要求也越来越高。双螺杆挤出机是连续混炼机中应用最多的一种设备,理所当然,也就受到大家的广泛关注,围绕它的研究也就越多。目前,根据国内外的发展趋势,双螺杆挤出机主要是向高速、大扭矩、大挤出量及低能耗转方面发展。剖分式同向平行双螺杆挤出机可快速打开机筒,进行物料清洗的高速大扭矩挤出机。二、结构特点剖分式同向平行双螺杆挤出机的显著特点即为:机筒可剖分式同时,螺杆和机筒内衬套可随意组合性。1、剖分式机筒。以往的双螺杆挤出机机筒是整体式的,无法打开。而剖分式双螺杆挤出机是分体式的,它由上下两半机筒组成,下半机筒固定在机架上,上半机筒通过蜗轮减速器联接在下半机筒上。平时上半机筒和下半机筒用两排螺栓栓紧,当需要打开机筒时,只需松开螺栓,将蜗轮箱手柄转动即开启机筒。2、积木式螺杆和机筒。剖分式双螺杆挤出机主机的螺杆、机筒均采用先进的“积木式”设计,螺杆由套装在芯轴上的各种形式的螺块组合而成,筒体内的内衬套根据螺块的不同可以调整,从而根据物料品种等工艺要求灵活组合出理想的螺纹元件结构形式,实现物料的输送、塑化、细化、剪切、排气、建压以及挤出等各种工艺过程,从而较好地解决了一般难以兼顾的所谓螺杆通用性与专用性的矛盾,达到一机多用、一机多能的目的。“积木式”设计的另一优点是对于发生了磨损的螺杆和筒体元件可进行局部更换,避免了整个螺杆或筒体的报废,大大降低了维修成本。l、主机双螺杆为高速同向啮合式,在各种螺纹及混炼元件中可产生十分强烈而复杂的物料传递交换、分流掺合以及剪切捏合等作用。这些作用可通过改变螺杆构型及操作工艺条件实现充分自如的调节控制,以满足适应各种工艺的要求。2、准确的计量、合理的加料方式是严格执行配方的关键,也是保证产品质量的第一关,我们根据物料的性能,用户的需要,配有多种喂料方式,如体积计量、动态失重计量等等,以满足不同产品的需要。3、先进的控制系统。该挤出机配有先进、美观的控制系统,其控制元件大部分都采用进口元件,质量好,灵敏度高。主机的运转参数如电流、电压、温度,扭矩等都很直观,所以操作起来非常方便,对操作工的要求也不高。4、系统配有拉丝水冷切粒、热切水冷、热切风冷等几种切粒方式。可根据材料不同、用户的要求进行配置。
