PRODUCT DESCRIPTIONPLD Vertical Bottom Discharge Scraper
Centrifuges with Pulling BagPLD automatic bottom discharge scraper
centrifuge is a new type of product that are developed
independently by HUADA, with multiple patents and completely
independent intellectual property rights. This series of products
is batch-processing separation centrifuge, After discharge, the
filter bag can be regenerated, with good filtration and high
efficiency, and it can effectively reduce the influence of the
residual cake layer on the filtration performance of materials,
avoid the cross contamination during material separation, and meet
the requirements of GMP and FDA, thus realizing remote intelligent
control and automatic production and online fault diagnosis.WORKING
PRINCIPLEMaterials to be separated are added into the high-speed
rotating centrifuge basket through the feeding pipe. Under the
action of the centrifugal field, the material will be filtered
through the filter cloth, the liquid phase will be discharged
through the liquid outlet, and the solid phase will be retained in
the basket. When the basket is filled with materials and the
feeding and dehydration stop, wash the cake and filter out the
washing liquid. The centrifuge continues to spinning to dry the
filter cake. After the cake meets the separation requirements, the
centrifuge slows down and the scraper removes the cake from the
bottom and out of the machine. Then, the centrifuge slows down
again and the pneumatic bag puller moves up and down to shake off
the residual cake, so as to completely remove the cake.PLD
Insulation-typeAdhering to the excellent characteristics of
conventional PLD products, it is designed in an insulation layer
structure with low or high temperature resistant bearings and
seals, and it can achieve solid-liquid separation of materials in
low or high-temperature environment.Insulation layer: single
insulation layer (insulation agent filling layer) or double
insulation layer (insulation agent filling layer + cold and hot
media circulation chamber).PQLD Pharma CentrifugesThe product is
designed with an overall turnover cover, and the transition of the
whole structure is smooth and flat, which can give a thorough
cleaning, effectively putting an end to the dead corners and can
remove online residuals to avoid cross-contamination of materials.
It is suitable for material separation requiring high purity and
hygiene.MAIN FEATURESThe filter bag is designed with a renewable
structure and it can well remove the residual cake, avoiding cross
contamination of materials. Moreover, it can improve the filtering
efficiency and prolong the service life of the filter
bag.Compliance with GMP specifications and anti-explosion
requirementsThe structure of a large turnover cover or overall
turnover cover + CIP online cleaning system can achieve thorough
cleaning in centrifuges.The high surface cleanliness and roughness
up to Ra0.2-0.4μm are in line with cGMP requirements.Smooth
discharge: Automatic scraper device has the functions of speed
regulation and pitch adjustment, and the scraper is designed with
multi-structures, including double-blade (wear-resistant: carbide
tip, wear-resistant coating, etc.). The cutting angle has been
improved, with smaller scraping resistance, and the layered
scraping technique shall be selected for hard materials.Small
vibration, low noise and stable operation: The liquid damping
shock absorber technology is adopted, and it is installed without
base, which effectively reduces the vibration of the centrifuge and
facilitates the installation and maintenance of the machine.Frame
square box design: The chassis weight is increased, the centrifuge
center of gravity is lowered, and the vibration speed is
reduced.The cake layer control device and electromechanical
material level detection device are provided to effectively control
the feeding amount, prevent the centrifuge from overload work,
prevent the material from escaping, and ensure the automatic
operation of the feeding process. The basket is
comprehensively machined and undergoes 100% weld flaw
detection, with high machining precision and large filtering area,
conducive to ultrafine particle filtration.Quick filter bag
replacementIt is designed with a detachable basket lip, reliable
self-locking, and scientific filter cloth fixed module (tensioning
device + quick assembly structure), by which, the filter cloth can
be replaced quickly.Fully enclosed structure: The material is
completely separated from the transmission, which can protect the
nitrogen filling inside the equipment, effectively prevent material
from contamination, and ensure the safety of personnel.Uniform
distribution: Streamline distributor can improve the
distribution balance and reduce the distribution vibration for the
material with poor fluidity. Multiple safety
protection and guaranteeIt has multiple protections, including
overvibration protection, overcurrent protection, temperature
control protection,
