Product features and applications
The PQSB series centrifuge is a flat plate clean and intermittent filtration equipment. The material is fed into the rotary drum through the feed pipe of the sealed casing. Under the action of centrifugal force, the liquid phase passes through the filter medium and is discharged outside the machine, while the solid phase is trapped inside the rotary drum. After stopping the machine, the machine cover is opened to discharge from the top. The equipment can be opened more than 90 degrees as a whole through manual, hydraulic, pneumatic and other methods, thereby exposing the entire drum components for easy unloading, cleaning, filter bag replacement and other operations. The whole machine is made in accordance with GMP and FDA certification standards, and the overall polishing has no dead corners. The PSFQ model adopts direct motor drive to avoid dust caused by V-belts, mechanical braking, etc., making it particularly suitable for flammable, explosive, and toxic environments.Main technical parameters

Structural schematic diagram and principle

Widely used for the separation and dehydration of solid phase suspensions containing medium to fine particles in the pharmaceutical, light industry, food, chemical and other sectors. Such as food additives, chemical condiments, sodium glutamate, pesticides, antibiotics, pharmaceutical intermediates, vitamins, traditional Chinese patent medicines and simple preparations, activated carbon, dye intermediates, pigments, etc.
main features
Full flip structure, smooth transition of structural components, polished surface to effectively eliminate hygiene blind spots. The external structural components, fasteners, and drum are made of stainless steel, which can thoroughly clean the centrifuge shell, drum, and liquid outlet tank.
The machine base is a flat plate structure, with a low center of gravity, small footprint, and easy operation.
Equipped with liquid damping shock absorbers, the vibration reduction effect is good and daily maintenance is simplified.
On the flip cover, there are feeding tubes, washing tubes, observation glasses, and lighting holes. Configure an online cleaning system (optional) to perform online cleaning on the inner wall of the centrifuge casing, the inner and outer surfaces of the drum, and the surface of the collection tank, ensuring cleanliness requirements and compliance with GMP standards.
Strong universality, with grains that are not easily broken, it can be used for separating suspensions with solid particles, as well as for separating fibrous materials, with a wide range of applications.
Using a frequency converter for smooth start-up and adjustable separation factor; Configure a nitrogen protection system (optional) to achieve explosion-proof requirements for enclosed structures, suitable for applications in toxic and flammable/explosive environments.
