Product Description:

LGZ series centrifuge is a type of centrifugal separation machinery with high scientific content, and several configuration options are available. Featuring hygienic, sterile, enclosed explosion-proof, multiple safety protections and several configuration options, this series centrifuge is controlled by a fully-automatic program, and has been widely used in such industries as pharmacy, fine chemistry and food.


Operating principle

The automatic bottom discharge scraper centrifuge is vertical fully-automatic filtration centrifuge. The motor drives the basket to rotate at high speed through the belt, and under the control of pre-written program, the material to be separated is fed into the basket through the feed system. After the material is filtered through the filtration medium (filter cloth/screen) under the action of centrifugal force, the liquid phase discharges out of the centrifuge through the liquid pipeline, and the solid phase is retained in the basket. A material detection device is used to detected material filling position in real-time manner, and when the solid cake deposited in the basket reaches the specified holding capacity of the centrifuge, feeding stops. Then wash and dry the solid cake. After the solid cake meets requirements for knock-out, the centrifuge reduces to the scraping rate, under the hydraulic (pneumatic) control, the scraper device removes the solid cake, and then the cake id discharged at bottom outlet of the centrifuge.

 

Applications

Apply to separating the suspension containing particles, but also fibers, especially the highly sticky, containing micro particles, poisonous and flammable materials, like antibiotics, vitamins, and minerals, salts, gourmet powders, foodstuff additives, amylum, sugar, chemical flavors, thiamin, plasters, Glauber's salt, bluestone, potassium chloride, borax, dyestuffs, pigment, resin, pesticides, and environmental protection. The centrifuge is highly automated, has large capacity and can be remote-controlled.

 

Main features

1. Platform base structure could lower the center of gravity and stabilize the machine. 4-point supporting, liquid vibration damping and no-foundation installation form; improved the vibration isolation and damping performance.

2. Independent inclined feed disk, even and controlled feed.

3. Air recoil and pneumatic auxiliary scraper: Minimizing the residual solid cake to facilitate filtering cloth regeneration.

4. Nitrogen protection system: ensuring the safety during the operation.

5. Big hinged cover and fully hinged cover constructions: Cleaning device is set inside centrifuge cavity to make online cleaning for the centrifuge and thus to avoiding cross contamination against the products.

6. Multiple safety protection devices: over-vibration protection, over-current protection, thermal control protection, cake layer controller, protection for scraper movement, protection when open the cover, various signs and warning identifications.

7. PLC control, touch screen, inverter control, dynamic braking, feedback braking, self-diagnosis of equipment fault, automatic control panel and DCS control interface.

8. Polished internal/external surfaces with roughness up to Ra0.2~0.4μm, complying with cGMP.

 

The PGZ series products retain the advantages of LGZ while adopting a fixed cover design, which is particularly suitable for the separation of toxic, volatile, flammable and explosive materials.
