An analysis of the mixers and blenders on exhibit high lights the following important trends in the develop-
ment of mixing equipment in other countries: increased intensity of mixing processes; combining of different unit
operations in a single piece of equipment; increased size of machinery and greater variety in service capabilities
(in vacuum, high pressure, heating, cooling, stainless steel or glass- and ceramic-lined steel, explosion proof de-
sign); automation of mixing operations; improvements in external design and packaging.
Inadequate attention is being given to continuous mixer designers, apparently because of the difficulties
caused by imperfections in accessory equipment, such as hopper and loading equipment. The need for continuous
mixing equipment is being felt more sharply as time goes on.
Of the large number of exhibits presented by the competing firms, quite a few were of standard design, even
closely duplicating theft" rivals, with only slight differences in design owing primarily to patenting considerations.
超过40多种的混频器的设计作品在展览会中被展览。MKF [ VEB机械制造-联合弗赖塔尔]西部(东德),板岩,沃纳-弗莱德尔,亨舍尔,ehrwecka,vibau(西德),愤怒(奥地利),科孚马,一(意大利),盖calade(法国),巴斯,bachoffen(瑞士),smurmans EN vanginneken(荷兰),niipon(日本)制造了这些机器。该模型可根据设计特点分为门混频器的,锚搅拌器,搅拌器涡轮螺旋桨搅拌器,搅拌器,磁盘,输送器叶片混频器,丝带搅拌机,搅拌机与形臂(西格玛或Z叶片),辊混合器,混合器和螺钉。众所周知,要达到混频器设计要求,只是最近才开始使用的工业类型的竞争;特别是混频器包括后者的发展和粗加工聚氯乙烯聚合物组合物。
德赖斯展览出helimat实验室模型混合器(如图1)设计的混合和塑化过程在悬浮法和乳液型聚氯乙烯组合物治疗。这些机器基于内部混合原理的基础上代替辊和密炼机。在内部混合,有剪切应力导致的磨损的材料及材料的加热层材料的过程中以不同的速度运动直接接触。
Helimat混合器具有圆筒状的分割室围着水平侧入轴,轴上有四双设置成单一角度的旋转轴线的平面装置。过程中,轴高速旋转产生的(1500至3000每分钟转速)离心力,通过叶片,使得聚合物因质量集聚在混合室壁上,这使得过程中的混合室中心部分产生空间。绕轴叶片的位置使得过程中的材料发生循环流动,达到外部混合的效果,即,对过程质量表面的不断更新。
该机可装微湿的或糊状物质;预混合的成分不是强制性的。只要在室内指示捏合过程已经达到一定的温度,混合器立刻关闭。混频器是一个自动清洗机清洗,但如果工作是切换到高对比度颜色的饲料时,额外的操作是必要的。该helimat是间歇式的,有短的操作周期(50到150秒)。自动离合器和制动器安装电动马达和搅拌之间轴带搅拌机快速停止。 混合搅拌设备英文文献和翻译(5):http://www.751com.cn/fanyi/lunwen_5951.html
