活塞推料離心機可分為臥式單級、二級或三級活塞推料。能在全速狀態下，連續進行進料、分離、洗滌、卸料等工序。具有連續操作、運轉平穩、分離因數高、生產能力大、洗滌效果好、濾餅含濕率低、母液含固量少等特點。

適合分離含固相物粒度大于0.08mm,濃度大干40%的懸浮液。適用于化工、化肥、制堿、制鹽等行業，特別適用于氯化鈉、氯化銨、碳酸氫銨、硫酸鈉、尿素等固液分離。

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.

主電機帶動套裝的內、外轉鼓全速旋轉，物料由進料管連續引入，均勻分布到內轉鼓內段濾網壁上，在離心力作用下，液相物穿過濾網和轉鼓壁濾孔排出，經排液管排出機外，固相物截留在內轉鼓形成環形濾餅層。

內、外轉鼓同速旋轉的同時，在活塞推動下，內轉鼓連續軸向往復運動，因而推料盤推動內轉鼓濾餅層間歇不斷地向外移動排出內轉鼓，進入外轉鼓進一步分離并形成環形濾餅層，內轉鼓外端面則推動外轉鼓濾餅層間歇不斷地向外移動排出外轉鼓，經刮料槽排出機外。

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系列離心機是一種臥式雙級活塞推料、連續操作過泥離心機。能在全速運轉下，連續進行進料、分離、洗滌、卸料等工序。具有連續操作、運轉平穩、分離因素高、生產能力大、產量高、洗滌效果好、濾餅含濕率低、母液含固量少等優點。

適合分離含固相物粒度大于0．08mm，濃度大于35％的懸浮液。適用于化工、化肥、制堿、制鹽等行業，特別適用于氬化鈉、氯化、碳酸氫銨、硫酸鈉、硫酸銨等固液分離。

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.
