Do You Understand Vertical Scraper Centrifuges?

Vertical Scraper Centrifuge Introduction


Vertical Scraper Centrifuge is a fully automatic separation equipment with a scientific structural design, high technical content, large processing capacity, and convenient operation and maintenance. It is mainly used for solid-liquid separation of suspensions containing solid phase particles and can also be used for solid-liquid separation of fibrous materials. Suitable for fibrous, suspension, high viscosity, fine particle size, toxic, flammable, and explosive materials with particle sizes ranging from 10μm~a few millimeters and solid content ranging from 5%~40%; such as antibiotics, vitamins, pharmaceutical intermediates, etc. used in pharmaceutical products, salt, MSG, food additives, starch, sugar, chemical seasonings, etc. used in food, ammonium sulfate, gypsum, mirabilite, copper sulfate, potassium chloride, borax, dyes, pigments, resins, pesticides, etc. used in chemical raw materials. It has features like sterility and hygiene, sealed explosion-proof, multiple safety protections, and can operate in plateau working conditions. It has been widely used in solid-liquid separation work in the pharmaceutical, fine chemical, new energy, food, and mining environmental protection industries.


Working Principle of Vertical Scraper Centrifuge


Vertical Scraper Centrifuge is a vertical fully automatic filter centrifuge. The control program opens the feed valve, letting the material to be separated enter the centrifuge through the feed pipe and distribution tray. Under the action of the centrifugal force field generated by high-speed rotation, liquid phase is discharged through the liquid outlet pipe after filtration through the filter medium(filter cloth/filter mesh), while solid phase is retained on the filter cloth. The material level detector detects the position of the material layer, and when the filter cake inside the drum reaches the set loading capacity, it automatically stops feeding. The filter cake is then washed and dehydrated as required by the customer. After the filter cake meets the separation requirements, the program controls the centrifuge to reduce to the scraping speed. Under the control of the liquid(gas) actuating device, the scraper device scrapes off the filter cake, which is then discharged through the outlet at the bottom of the centrifuge.


Why UseVertical Scraper Centrifuge


  • Good adaptability: By indicating the physicochemical properties, process requirements, and installation sites for the material to be processed before purchase, the user will be provided with a suitable model.


  • Strong production capacity: Continuous operation 24 hours a day, large processing capacity, and good separation effect.


  • Fully automatic operation, reliable operation: Enables remote control, no need for manual intervention, reducing labor costs.


  • Fully sealed structure: Nitrogen protection in the machine interior, bearing chamber, and scraper chamber. The separation of suspension occurs in an enclosed state, leading to no contamination of the operational site and maintaining clean and hygienic production environment.


  • Strong corrosion resistance.


  • Energy-saving and environmentally friendly: Adopts advanced PLC variable frequency control system, consumption or regenerative braking method to reduce energy consumption and save costs.


  • Online cleaning device: Can effectively clean the inside of the centrifuge, with high polishing precision, smooth and simple internal structure, and no cleaning dead ends.


  • Reliable main shaft sealing, ensuring no leaks.


  • Can be sterilized at high temperatures.


The advantage of Vertical Scraper Centrifuge lies in its advanced separation principle and process characteristics. Through detailed material analysis and experiments, the most suitable model and configuration can be determined to enhance production efficiency and product quality.
