Heavy-Duty Self-Cleaning Centrifuge for Liquid / Solid Separation & Filtration

Bowl diagram and operating description: Seal water (1) is introduced into the bowl to seal the heavy phase liquid discharge to begin the process. Product is introduced through the hermetic style product feed (2) and the light phase liquid is discharged under pressure by a centripetal pump (5) installed inside the bowl. The heavy phase liquid (4) discharges into the covers and gravity drains. The sludge chamber (6) features a relatively large volume solids holding capacity for high efficiency separation and maximum process time between centrifuge bowl clean outs. The bowl and all the components that are in contact with the product are easily removed and disassembled for quick easy cleaning.

Centrifuge Bowl: Manual clean bowl assembly features the bowl bottom and top made of duplex stainless steel for superior mechanical strength and chemical resistance. The bowl lock-ring is made of special AISI 400 series stainless steel. The internal bowl parts such as the distributor, conical separating discs, feed distributor, and the light phase centripetal discharge pump is made from AISI 316 stainless steel.

Frame and Covers: Manufactured of cast iron, sandblasted, heat-treated, and epoxy painted. The frame must be secured to the floor using the supplied vibration absorbers and foundation bolts. The covers are made in aluminium and bolt to the base frame. The covers position the feeding pipe and the centripetal outlet pumps of the clarified liquid phases.

Drive: The horizontal shaft is moved through a mechanical coupling by an electric motor flanged directly onto the equipment frame and controlled by an inverter. On the horizontal shaft a worm-wheel gear engages the pinion gear fitted directly on the spindle, and the assembled bowl fits onto the tapered end. All the rotating shafts are mounted on ball bearings. The top vertical shaft bearing is located inside an appropriate shock-absorber collar, specifically designed to compensate for all radial vibrations.

Lubrication: Automatic splash lubrication is provided by an oil bath inside the frame. Appropriate caps allow the filling and emptying of the oil. A sight glass allows for easy inspection and control of the lubricating oil level.
