ZDR系列錕式熱分散機(jī)/ ZDR Series Roll Type Disperser

用 途 ：

ZDR系列輥式熱分散機(jī)是單輥式熱分散機(jī)，是目前廣泛使用的廢紙熱分散的關(guān)鍵設(shè)備。二般用于分散廢紙中的油脂、石蠟等熱熔性及膠粘性雜質(zhì)和特殊性油墨粒子。

結(jié)構(gòu)特點(diǎn):

ZDR系列輥式熱分散機(jī)由轉(zhuǎn)子裝置、定子裝置、機(jī)體、進(jìn)料口、出漿口及傳動(dòng)裝置、控制系統(tǒng)、加熱系統(tǒng)等組成。漿料以

≥28%的濃度進(jìn)入熱分散機(jī);漿料在機(jī)體內(nèi)由蒸汽加熱至1 00℃以上，同時(shí)漿料隨轉(zhuǎn)子的旋轉(zhuǎn)的軸向力的作用

和轉(zhuǎn)子與定子的相對(duì)運(yùn)動(dòng)作用而受到強(qiáng)烈的攪拌、剪切和搓揉，使粘附在纖維上的熱熔物、膠粘物及油墨等雜質(zhì)從纖維上剝離并分散成微細(xì)顆粒，同時(shí)也使混雜在漿料中的塑料、橡膠等雜質(zhì)顆粒凝縮成球狀物，從而易于在后續(xù)的篩選或洗滌工段中除去。不損害纖維本身特性。能有效地分散、除去廢紙漿中難處理的油墨粒子及濕強(qiáng)紙的紙漿。在之28%濃度及上100° C溫度狀態(tài)下，熱分散機(jī)的攪拌、剪切與搓揉作用有效地分散油脂、石蠟等熱熔性雜質(zhì)，也能分解紙漿中熔點(diǎn)較高的雜質(zhì)，使之易于去除。設(shè)備結(jié)構(gòu)穩(wěn)定可靠，維修和操作方便安全。可靠的氣控出漿與負(fù)荷控制等系統(tǒng)，可確保熱分散機(jī)的工作得到最佳的效果。

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.
