         PGZ系列刮刀下卸料全自動離心機是一種自動化程度高、可實現全自動程序控制的間歇式分離機械,具有多種配置可供選擇。該系列產品具有無菌衛生、密閉防爆、多重安全保護等特點。適用于細顆粒和中等顆粒度固相懸浮液的固液分離,也可用于纖維狀物料的固液分離,如:石膏、硫酸、硫酸銅、氯化鈉、硼砂染料樹脂、農藥農劑等化工行業;食鹽、味精食品添加劑淀粉、制糖、調味品等食品行業;抗生素、維生素等制藥行業及礦物、環保等其它行業。
 
PGZ series automatic scraper bottom discharge centrifuge,operates intermittently and fully automatic programmed.It has properties of sterile,sealed and explosion-proof,and safety protection.It is suit for separation of solid suspension includes tiny and medium particles,also suit for separation of fibrous material.Application field:chemical industry,food industry,pharmaceutical industry,mining industry and environmental protection industry,etc.
 
 

◎工作原理

         

Working principle

        待分離物料由進料管進入高速旋轉的離心機轉鼓,在離心力場的作用下,均布在轉鼓內壁的濾布上,進行過濾分離。分離過程中液相透過固相物料、濾布的縫隙和轉鼓壁上的小孔,從底盤的出液管流出;而固相物料則被截留在轉鼓壁內。達到分離要求后,通過刮刀自動下部卸料,出渣口排出。
 
Material comes into rotating drum trough feed tube,centrifugal force field makes it spread evenly on filter cloth of interior wall.During separation process,liquid trough gap within solid phase and filter cloth also holes of drum wall,discharges by outlet.While solid material retained within drum wall.After separation,scraper cut filter cake into pieces,discharges by outlet.The last step is self-cleaning,remove solid residues.
