Vertical Bottom Discharge Scraper Centrifuges(Pharma Centrifuges)

应用领域: It is mainly used for solid-liquid separation of the suspension of various kinds of solid particles and fibrous materials, especially toxic, flammable and explosive materials and those materials with high viscosity and fine particle size. For example, medical products such as antibiotics, vitamins and medical intermediates, food such as salt, monosodium glutamate, food additives, starch, sugar and chemical seasoning, chemical materials, such as ammonium sulphate, gypsum, mirabilite, copper sulphate, potassium chloride, borax, dye, pigment, resin and pesticide, and materials related to industries concerning lithium ternary precursor new energy, mining, metallurgy and environmental protection.

· Product Introduction

PLD 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 Principle

Materials 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.

· Process Chart

Cake removal rate higher than 99%

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.

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.

Quick filter bag replacement

It 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.

Uniform distribution

Streamline distributor can improve the distribution balance and reduce the distribution vibration for the material with poor fluidity.

Comprehensively machined

The basket is comprehensively machined and undergoes 100% weld flaw detection, with high machining precision and large filtering area, conducive to ultrafine particle filtration.

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.

Multiple safety protection and guarantee

It has multiple protections, including overvibration protection, overcurrent protection, temperature control protection, scraper in-situ position protection, scraper stroke protection, cap protection, interlock protection, scraper blocking protection, nitrogen protection, etc.
