活塞推料离心机可分为卧式单级、二级或三级活塞推料。能在全速状态下，连续进行进料、分离、洗涤、卸料等工序。具有连续操作、运转平稳、分离因数高、生产能力大、洗涤效果好、滤饼含湿率低、母液含固量少等特点。

适合分离含固相物粒度大于0.08mm,浓度大干40%的悬浮液。适用于化工、化肥、制碱、制盐等行业，特别适用于氯化钠、氯化铵、碳酸氢铵、硫酸钠、尿素等固液分离。

Piston push centrifuge can be divided into horizontal single-stage, two-stage or three-stage piston push. In the full speed state, continuous feeding, separation, washing, unloading and other processes. It has the characteristics of continuous operation, stable operation, high separation factor, large production capacity, good washing effect, low moisture content of filter cake, low solid content of mother liquor and so on. 

It is suitable for the separation of suspension containing more than 0.08 mm particle size and 40% dry concentration. 

It is suitable for chemical industry, chemical fertilizer, alkali production, salt production and other industries, especially for solid-liquid separation of sodium chloride, ammonium bicarbonate, sodium sulfate, urea and so on.

主电机带动套装的内、外转鼓全速旋转，物料由进料管连续引入，均匀分布到内转鼓内段滤网壁上，在离心力作用下，液相物穿过滤网和转鼓壁滤孔排出，经排液管排出机外，固相物截留在内转鼓形成环形滤饼层。

内、外转鼓同速旋转的同时，在活塞推动下，内转鼓连续轴向往复运动，因而推料盘推动内转鼓滤饼层间歇不断地向外移动排出内转鼓，进入外转鼓进一步分离并形成环形滤饼层，内转鼓外端面则推动外转鼓滤饼层间歇不断地向外移动排出外转鼓，经刮料槽排出机外。

The main motor drives the inner and outer drum of the suit to rotate at full speed, and the material is continuously introduced by the feed tube and evenly distributed on the filter wall of the inner section of the inner drum, and under the action of centrifugal force, the liquid phase is discharged through the filter and the filter hole of the drum wall, 

After the discharge pipe is discharged from the machine, the solid phase is intercepted into the inner drum to form a ring filter cake layer. 

The inner drum and the outer drum rotate at the same speed, and at the same time, under the push of the piston, the inner drum moves continuously axially and reciprocating, so that the pushing plate pushes the inner drum filter cake layer to intermittently move outward and expel the inner drum, 

Entering the outer drum to further separate and form a ring filter cake layer, the outer end face of the inner drum pushes the outer drum filter cake layer to move out of the outer drum intermittently, and discharges the outer drum through the scraping tank.

HR系列离心机是一种卧式双级活塞推料、连续操作过泥离心机。能在全速运转下，连续进行进料、分离、洗涤、卸料等工序。具有连续操作、运转平稳、分离因素高、生产能力大、产量高、洗涤效果好、滤饼含湿率低、母液含固量少等优点。

适合分离含固相物粒度大于0．08mm，浓度大于35％的悬浮液。适用于化工、化肥、制碱、制盐等行业，特别适用于氩化钠、氯化、碳酸氢铵、硫酸钠、硫酸铵等固液分离。

HR series centrifuge is a kind of horizontal two-stage piston pushing and continuous operation mud centrifuge. It can continuously carry out feeding, separation, washing, unloading and other processes under full speed operation. The utility model has the advantages of continuous operation, stable operation, high separation factor, large production capacity, high output, good washing effect, low moisture content of filter cake, low solid content of mother liquor and so on. 

It is suitable for the separation of suspension containing solid phase with particle size more than 0.08 mm and concentration more than 35%. 

It is suitable for chemical industry, chemical fertilizer, alkali production, salt production and other industries, especially for solid-liquid separation of sodium argon, chlorination, ammonium bicarbonate, sodium sulfate, ammonium sulfate and so on.
