SGZ Automatic Scraper Bottom Discharge Centrifuges

How to Work
Once the materials to be separated enter the fast-spinning basket, they will be filtrated by the filter liner under the centrifugal force. The liquid flows out through the liquid outlet, but solids deposit on the internal wall of the basket. Once the solids cake reaches the holding capacity, feeding stops. Clean the solids cake, and then drain out the washing water. Stop the machine. For SS, SB, PSB, PBZ series, the solids cake is discharged manually. For SD, PSD series, use the filter liner lifting tool pull out the filtering liner with solid cake, and take to the discharging place. Open the bag and take out the solid cake. Put the liner back to the machine and resume the machine.

Model SSC Centrifuge is three-column sedimenting top discharge centrifuge, the materials to be separated enter into the drum of the centrifuge rotating at high speed through a feeding tube, affected by the centrifugal force, the heavy phase material is sedimented to the outer layer of the drum, the light phase material is left on the inner layer of the drum. (In case of little heavy phase material and long-time feeding of small flow, the light phase material will overflow from the regulating opening). When sediment requirement is reached, operate the skimming device, the skimming pipe will enter into the drum, light phase material will skim from this pipe, the heavy phase material (filter cake) will remain on the drum, which will be discharged manually.

Applications

Apply to separating the suspended liquid contained particles, but also fibers, like plasters, bluestone, potassium chloride, borax, dyestuffs, pesticides, salts, gourmet powders, foodstuff additives, chemical flavors, antibiotics, vitamins, the metals like copper, zinc and aluminum, metal products, sludge and waste water treatment.

Features

1. PLC based control with programmable setup. Automatic operation with no operator attention monitors the whole process including feeding, first cycle filtration, cleaning, intensive filtration and discharging.
2. Inverter for speed regulation makes startup smooth. Relative centrifugal force is adjustable.
3. Dynamic braking. Non-touching braking doesn't produce dusts.
4. Leak-proof structure with silicone rubber or fluoroelastomers seals. It meets the requirement of general closed.
5. Programmed electromechanical feeding control.
6. Safety protection: Rotation rate detection, vibration protection, motor overload and overheat protection, dual control with both electrical and mechanical to scrapers and the lifting device, interlocking the scraper and drum.

Our machinery can be used for chemical or pharmacy-manufacturing. It should be specifically chosen so as to meet the technical and economical requirements.
