Description

将粒料和填料输送给挤出机的挤出机螺杆的装置
本发明涉及将粒料和填料输送给挤出机的挤出机螺杆的装置，包括：旋风分离器，其具有用来加入气动输送填料的输送流的进料口以及用来将从输送流中分离出的填料排出的出料口；用于新鲜粒料的加料斗；以及混合段，其中从加料斗将填料和新鲜粒料输送给混合段。
对网格布例如由单轴拉伸聚合物丝、尤其是聚烯烃丝、优选聚丙烯丝制成的网格布进行涂层处理时，当机组起动并且随后对涂层进行修边时，就会产生大量的废料。为了能够使用该废料并且提高经济效益，已提出了各种不同的建议。例如公知的是，将这些废料加工成再生材料，然后送回到挤出机。尤其是已经提出，将条形的边料直接送回到挤出机的加料斗之中。但是在此仍然会出现显著的困难，尤其是因为在此必须以与产生边条的速度相等的速度抽出切割下来的边条，并且也必须以该速度将其拉入挤出机的加料斗之中。
因此另一建议在于，将切割下来的边条切碎，并且将切碎的边条与新鲜粒料混合并输送给挤出机螺杆。
在此，例如在DE 2308698 A中所描述的是，以气动方式输送在切碎装置中切碎的边条，并且将输送流提供给离心分离机、尤其是旋风分离器，在所述离心分离机中，切碎的边条从输送流中分离出来，并且落入垂直螺旋输送器的输送路径之中。螺旋输送器将切碎的边条运送给混合段，在混合段中将其与新鲜粒料混合。随后将混合物递交给挤出机螺杆，在其中使得混合物均匀化并且熔化。
所述方法的缺点在于，切碎的废料在旋风分离器的出料口处有形成架桥的倾向，从而存在堵塞出料口的危险。形成架桥会使得螺旋输送器的充盈率改变或者减小。有一系列形成架桥的原因，例如切片的静电、切片附聚的倾向、以及切片的微小重量。各个切片的尺寸越小，则形成架桥的危险越大。形成架桥的倾向还依赖于一系列环境条件，例如环境热量和湿度，从而总体上存在不可控、并且因此无法令人满意的情况。螺旋输送器的变化或减小的充盈率一方面会导致螺旋输送器的不可靠和易错的运行，从而需要频繁中断运行来排除可能存在的故障。另一方面会因此而减小切片在挤出机螺杆中所占的比例，使得需要相对较大量的新鲜粒料的，从而提高成本。
本发明的目的在于，更加可靠地构造切碎的废料到挤出机中的送回，其中尤其要避免切片形成架桥，并且改善从旋风分离器中输出切片时的质量流量并且使其均匀化。此外也要实现其它任意的填料作为所述的切片的送回或者输送。最后结构设计应当尽可能节省空间，以便能够缩短输送路径。
为了解决这一任务，本发明在开头所述类型的装置中主要规定：将旋风分离器至少部分布置于加料斗之中并且与其同轴布置，使得旋风分离器的出料口沉浸到加料斗的环状包围出料口的出料区中，并且喂料螺杆沿轴向穿过旋风分离器的出料口，并且伸入到轴向邻接出料口的混合段中。通过现在并非借助于在出料口下方垂直延伸的螺杆、而是借助于轴向穿过出料口的喂料螺杆输出填料、尤其是切片，能够大大提高螺杆的充盈率。通过不再单纯基于重力从旋风分离器中排出填料、而是借助于喂料螺杆强制输送填料穿过出料口，可防止附聚的填料堵塞出料口。通过旋风分离器内部的空气循环使填料保持松散，可防止喂料螺杆的进入区中发生堵塞。
旋风分离器和用于新鲜粒料的加料斗的同轴布置导致形成特别紧凑的构造方式，该构造方式不需要长的输送路径。从而提高可靠性，并且将运行成本最小化。在此，旋风分离器的出料口沉浸到加料斗的环状包围出料口的出料区中，使得填料从旋风分离器中排出之后立即与新鲜粒料混合。因此不需要垂直输送到特殊的混合设备，而是在轴向邻接出料口的混合段中进行混合，其中通过喂料螺杆伸入到混合段之中来促进混合或者继续输送。喂料螺杆优选穿过整个混合段，并且在横向于喂料螺杆延伸的挤出机螺杆直接上方终止。这导致提高挤出机螺杆的充盈率。
一种优选实施方式规定，喂料螺杆的轴沿轴向穿过旋风分离器，并且经由潜管从旋风分离器向外引出。在向外引出的片段中，合适的驱动装置与轴啮合，以使得轴旋转。
通过如下方式来实现特别有效地从旋风分离器中输出填料：旋风分离器具有锥形变细的分离段和与其邻接的柱形输送区，喂料螺杆穿过该输送区延伸，并且该输送区的内直径基本上对应于喂料螺杆的外直径。
通过如下方式来有利地进一步提高喂料螺杆的充盈率：喂料螺杆在分离段的最下面的片段中具有锥形的在输送方向上收敛的包络面。这样保证聚集在旋风分离器的分离段最下端处的填料被挤压到柱形输送区的进入区中。喂料螺杆的锥形起始片段还可使得喂料螺杆在其轴易于断裂的情况下不会穿过出料口从旋风分离器中脱落并与挤出机螺杆相撞，这可能导致设备部件严重受损。
另一种优选改进方案规定，混合段呈漏斗形，具有在输送方向上变细的横截面。这导致压实由新鲜粒料和填料构成的混合物，并进一步导致改善挤出机螺杆中的混合的更好的均匀化。
优选地通过如下方式实现进一步减小输送路径：混合段具有邻接挤出机螺杆的出口，并且喂料螺杆一直延伸到出口。
为了避免利用喂料螺杆所输送的填料跟随旋转，一种优选改进方案规定，柱形输送区在其与喂料螺杆协作的内圆周处具有纵向延伸的槽。这些槽的深度有利地在输送方向上连续减小，也就是这些槽逐渐消失。通过设置所述槽，可在螺杆的开槽喂料段中明显提高输送材料在圆筒内壁上的摩擦系数。
现在根据示意图中所示的实施例对本发明进行更详细解释。其中附图1示出了根据本发明的装置的透视图，附图2示出了根据附图1的装置的透视剖面图，并且附图3示出了沿着横向于挤出机螺杆延伸的平面的剖视图。
附图1所示为新鲜粒料的加料斗1，以附图标记2表示其加料口。加料斗具有第一柱形片段3和与其邻接的漏斗状、也就是朝向出料口4呈锥形变细的片段5。具有环形法兰7的柱形出料区6与漏斗状片段5邻接，漏斗状、即朝向出口8呈锥形变细的输送片段9固定在环形法兰7上，该输送片段9构成混合段。输送片段9连接到挤出机螺杆11的供料管10上。
如在附图2和3中可更好地看出那样，将旋风分离器12同轴布置在加料斗1之中，旋风分离器的进料筒13从加料斗1伸出。管件14沿切向接入进料筒13之中，经由该管件14将填料尤其是切片废料的输送流输送给旋风分离器12。在进料筒13中，所引入的输送流通过切向吹入被置于圆形轨道上。由于构成分离段的邻接锥体15逐渐变细，旋转速度增大得使得切片被离心力抛向锥体壁并且减速到使得其从料流中脱离并且向下朝向出料口16方向流动。输送介质、尤其是空气经由中间的潜管17向上离开锥体15。
从附图2和3可以看出，旋风分离器12紧接在锥体15之后具有柱形输送片段18，其中出料口16位于该输送片段18的端部处。喂料螺杆19在轴向穿过柱形输送片段18和出料口16，并且与驱动轴20相连，该驱动轴经由潜管17从旋风分离器向外引导出。驱动轴支承在传动装置21之中，该传动装置21固定在平台22上，该平台22通过多个支柱23支撑在旋风分离器12的顶壁处。电机24通过传动装置21驱动驱动轴20。喂料螺杆19与柱形片段18协作，以用于将聚集在锥体15下端处的切片沿轴向输送出。直接在柱形输送片段18的上方、即在锥体15的最下面的片段中，喂料螺杆19具有锥形的朝向柱形输送片段18逐渐变细的包络面，从而能够提高喂料螺杆19的充盈率。喂料螺杆19还超出出料口16从旋风分离器12伸出，并且延伸到由漏斗状输送片段9所形成的混合段中直至挤出机螺杆11。在输送片段9中设置有具有管件25的维护和检查口，可以通过该管件25排除运行期间可能出现的异常、例如堵塞。
