Description

一种密炼机
技术领域：
本发明涉及一种橡胶加工设备，具体涉及一种密炼机。
背景技术：
橡胶加工，将橡胶制成橡胶制品的工艺过程。各种橡胶制品加工的基本过程包括塑炼、混炼、压延或压出（即挤出）、成型和硫化等基本工序，为了能将各种所需的配合剂加入橡胶中，生胶首先需经过塑炼提高其塑性；然后，通过混炼将炭黑及各种橡胶助剂与橡胶均匀混合成胶料；在这个过程中，密炼机作为最常用的生产设备。
密炼机一般由密炼室、两个相对回转的转子、上顶栓、下顶栓、测温系统、加热和冷却系统、排气系统、安全装置、排料装置和记录装置组成。密炼机工作时，两转子相对回转，将来自加料口的物料夹住带入辊缝受到转子的挤压和剪切，穿过辊缝后碰到下顶拴尖棱被分成两部分，分别沿前后室壁与转子之间缝隙再回到辊隙上方。在绕转子流动的一周中，物料处处受到剪切和摩擦作用，使胶料的温度急剧上升，粘度降低，增加了橡胶在配合剂表面的湿润性，使橡胶与配合剂表面充分接触。配合剂团块随胶料一起通过转子与转子间隙、转子与上、下顶拴、密炼室内壁的间隙，受到剪切而破碎，被拉伸变形的橡胶包围，稳定在破碎状态。同时，转子上的凸棱使胶料沿转子的轴向运动，起到搅拌混合作用，使配合剂在胶料中混合均匀。配合剂如此反复剪切破碎，胶料反复产生变形和恢复变形，转子凸棱的不断搅拌，使配合剂在胶料中分散均匀，并达到一定的分散度。
这种密炼机由于两个转子相对回转，其密炼效率较低。
发明内容：
本发明的目的是针对上述存在的问题提供一种密炼机，采用上下两对转子的挤压摩擦，结合中间疏料杆的物料疏通作用，上下转子协调工作，提高炼胶效率。
