PGD系列抖袋式刮刀下部卸料離心機是在保持了LGZ系列產品的固液分離刮刀卸料等主要功能的基礎上，增加了以抖袋方式清除殘余濾餅層的功能，去除率可達99%以上。避免了不同批次間產品分離的交叉混批，同時解決了殘余濾餅層對過濾速率的影響。主要應用于制藥、食品、化工、新能源等行業的固液分離工藝。

On the basis of maintaining the main functions of LGZ series products such as solid-liguid separation scraper discharging.PGD series bagging scraper lower discharging centrifuge has added the function of removing residual cake layer by bagging, and the removalrate can reach more than 99%. The cross-mixing batches of product separation between different batches were avoided, and the effect of residual cake layer on the filtration rate was solved. lt is mainly used in solid-liquid separation process in pharmaceutical,food,chemical and new energy industries。

工作原理

Operating principle

待分離的物料經進料管加入高速旋轉的離心機轉鼓內，在離心場的作用下，物料經濾布實現過濾，液相經出液管排出，固相則被截留在轉鼓內。當物料被加滿時，停止進料，對濾餅進行洗滌，同時將洗滌液濾出。離心機繼續旋轉，對濾餅進行甩干。濾餅達到分離要求后，離心機降速，通過刮刀將濾餅刮下從底部排出機外。離心機再降速，氣動拉袋裝置上下往復運動，將殘余濾餅抖落，實現濾餅的清除從而實現濾布再生。

The material to be separated is added into the high-speed rotating centrifuge drum through the feed tube.Under the action of centrifugal field the material is filtered through the filter cloth,the liquid phase is discharged through the outlet tube,ａnd the solid phase is intercepted in the drum.When the material is full,stop feedingwash the cakeａnd flter out the washingliquidThe centrifuge continued to rotate and the cake was dried After the fiter cake meets the separation requirement, the centrifuge reduces the speed and scrapes the fiter cake down from the bottom and discharges it out of the machine through the scraper.The centrifuge reduces the speed againａnd the pneumatic bag pulling

device moves up and down to shake off the residual filtercakeso as to realizethe complete removal of the filter cake thereby realizing the regeneration of the ffiter cloth

PGD離心機主要特點

Main features of PGD centrifuge

本機除兼備LGZ離心機的全部主要特點外還具有下列特點:

抖袋式去除殘余濾餅。通過氣動抖袋裝置的上下往復運動，將刮刀卸料殘余的濾餅全部清除，實現卸料和濾布再生。特殊設計的轉鼓攔液板結構，自鎖可靠，濾布更換方便容易。外置式氣缸+連桿驅動設計，工作可靠。

全封閉式出料斗設計，使物料與傳動機件隔離。

in addition to all main leatures of the LGZ series centrifuge.the PLD series centrifuge features as follows:

Removing the residual solid cake by bag-shaking method Eliminate all solid cakes left over the process of scraper dischargina through

reciprocal movement of the pneumatic pulling bag device,to realize complete discharging and filtering cloth regeneration.+ Design of removable lip ring in the basket with reliable selflocking, which is easy for changing the filter cloth. Extemal cylinder+rod drive design reliable in work

+ Fully-enclosed discharge hopper design separating the materal from the driving components of the centrifuge
