         PGZ系列刮刀下卸料全自动离心机是一种自动化程度高、可实现全自动程序控制的间歇式分离机械,具有多种配置可供选择。该系列产品具有无菌卫生、密闭防爆、多重安全保护等特点。适用于细颗粒和中等颗粒度固相悬浮液的固液分离,也可用于纤维状物料的固液分离,如:石膏、硫酸、硫酸铜、氯化钠、硼砂染料树脂、农药农剂等化工行业;食盐、味精食品添加剂淀粉、制糖、调味品等食品行业;抗生素、维生素等制药行业及矿物、环保等其它行业。
 
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

        待分离物料由进料管进入高速旋转的离心机转鼓,在离心力场的作用下,均布在转鼓内壁的滤布上,进行过滤分离。分离过程中液相透过固相物料、滤布的缝隙和转鼓壁上的小孔,从底盘的出液管流出;而固相物料则被截留在转鼓壁内。达到分离要求后,通过刮刀自动下部卸料,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.
