PGD Bag Shaking Scraper Bottom Discharge Centrifuge

PGD Bag Shaking Scraper Bottom Discharge Centrifuge

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.

Description

Operating principle

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.

Main features

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.
