PGD抖袋式刮刀下部卸料离心机

PGD系列抖袋式刮刀下部卸料离心机是在保持了LGZ系列产品的固液分离刮刀卸料等主要功能的基础上，增加了以抖袋方式清除残余滤饼层的功能，去除率可达99%以上。避免了不同批次间产品分离的交叉混批，同时解决了残余滤饼层对过滤速率的影响。主要应用于制药、食品、化工、新能源等行业的固液分离工艺。

The lower discharge centrifuge of the PGD series jitter bag scraper is based on maintaining the main functions of the solid-liquid separation scraper discharge of LGZ series products, and adds the function of removing the residual filter cake layer by shaking the bag, and the removal rate can reach more than 99%. Cross-mixing batches of product separation between batches are avoided, and the influence of residual cake layers on filtration rate is solved. Mainly used in pharmaceutical, food, chemical, new energy and other industries solid-liquid separation process.

工作原理

Operating principle

待分离的物料经进料管加入高速旋转的离心机转鼓内，在离心场的作用下，物料经滤布实现过滤，液相经出液管排出，固相则被截留在转鼓内。当物料被加满时，停止进料，对滤饼进行洗涤，同时将洗涤液滤出。离心机继续旋转，对滤饼进行甩干。滤饼达到分离要求后，离心机降速，通过刮刀将滤饼刮下从底部排出机外。离心机再降速，抖袋装置往复抖动，将残余滤饼抖落，实现滤饼的完全清除，从而实现滤布再生。

The material to be separated is added into the high-speed rotating centrifuge drum through the feed tube. Under the action of centrifugal field, thematerial is fltered throueh the flter coth.the iauid phase is dischareed throueh the outlet tube. and the solid phase is intercented in the drum.When thematerial is ful,stop feeding, wash the cake, and flter out the washing liouid. The centrifuge continued to rotate and the cake was dried. After the flter cakemeets the separation requirement, the centrifuge reduces the speed and scrapes the flter cake down from the bottom and discharees t out of the machinthrough the scraper, The centrifuge reduces the speed again, and the pneumatic bag shaking device moves up and down to shake of the residual filter cakeso as to realize the complete removal of the filter cake, thereby realizing the repeneration of the filter cloth.

主要特点

Main features 

本机除兼备LGZ离心机的全部主要特点外还具有下列特点:

-通过气动抖袋装置的上下往复运动，将刮刀卸料残余的滤饼全部清除，实现完全卸料和滤布再生。

-特殊设计的转鼓拦液板结构，自锁可靠，滤布更换方便、容易。

-内置拉袋气缸，抖袋动作双气道进气，提高拉伸力，复位缓冲装置，结构简单可靠。

-具有更大的作用力、更好的残余滤饼清除效果、保养维护更方便快捷。

-全封闭式出料斗设计，使物料与传动件完全隔离。

In addition to all main features 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 discharging 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 self-locking, which is easy for changing the filter cloth.

Built-in bag puling cylinder, double airway air intake, improve puling force, reset buffer device, simple and reliable structure. 

With greater force, betterresidual cake removal effect, maintenance more convenient and fast.

Fully-enclosed discharee hopperseparating the material from the driving components of the centrifuge.
