ZDR系列锟式热分散机/ ZDR Series Roll Type Disperser

ZDR系列锟式热分散机/ ZDR Series Roll Type Disperser

用 途 ：

ZDR系列辊式热分散机是单辊式热分散机，是目前广泛使用的废纸热分散的关键设备。二般用于分散废纸中的油脂、石蜡等热熔性及胶粘性杂质和特殊性油墨粒子。

结构特点:

ZDR系列辊式热分散机由转子装置、定子装置、机体、进料口、出浆口及传动装置、控制系统、加热系统等组成。浆料以

≥28%的浓度进入热分散机;浆料在机体内由蒸汽加热至100℃以上，同时浆料随转子的旋转的轴向力的作用

和转子与定子的相对运动作用而受到强烈的搅拌、剪切和搓揉，使粘附在纤维上的热熔物、胶粘物及油墨等杂质从纤维上剥离并分散成微细颗粒，同时也使混杂在浆料中的塑料、橡胶等杂质颗粒凝缩成球状物，从而易于在后续的筛选或洗涤工段中除去。不损害纤维本身特性。能有效地分散、除去废纸浆中难处理的油墨粒子及湿强纸的纸浆。在之28%浓度及上100° C温度状态下，热分散机的搅拌、剪切与搓揉作用有效地分散油脂、石蜡等热熔性杂质，也能分解纸浆中熔点较高的杂质，使之易于去除。设备结构稳定可靠，维修和操作方便安全。可靠的气控出浆与负荷控制等系统，可确保热分散机的工作得到良好的效果。

Application:

ZDR series roll type disperser is a single roll type one, and is a key machine widely used for the dispersion of waste paper pulp. It is generally used to deal with hot melt and sticky impurities such as grease and paraffn wax, and special ink particles. It is also called kneader.

Design Features:

ZDR series roll type disperser consists of rotor, stator, body, feeding inlet, outlet, driving device, control system and heating system, etc.

The pulp-feeding screw conveys the pulp at a consistency of 28% or higher into the disperser. The pulp is heated to 100 ° C by steam in the Meanwhile, the pulp is intensively stirred, sheared and kneaded in between the rotor and stator. As a result, the impurities that are body stuck to fibers, such as hot-melting and sticky substances as well as ink, etc. Are peeled off from the fibers a nd dispersed into line particles;

meanwhile, the impurity particles that mix in the pulp, such as plastics and rubber, etc., shrink into grain particles so that they are easy to be removed in the following screening and pulp-washing sections. No spoil to the fber itself.

High effciency in dispersing and removing ink particles and pulp of wet strength paper which are difficult to be removed in waste paper pulping.

Under the conditions of consistencies of 28% or higher and temperatures equal to or higher than 100'C, the disperser's stirring, shearing and kneading functions can disperse hot melt impurities effectively, such as grease and paraffn wax, etc. And the impurities with high melting points can also be dissolved for easy removal.

Steady and reliable structure, easy and safe in maintenance and operation. Reliable systems, such as pneumatic controlled pulp-discharging and load controlling system, and so on, ensure the optimal performance of the disperser.
