Disc Centrifuge Features: 

Toper high quality disc centrifuge consists of a frame that has a horizontal drive shaft with clutch and brake, worm gear , lubricating oil bath and vertical bowl spindle in the lower part of the disc centrifuge. The disc centrifuge bowl is mounted on top of the spindle in the lower part. The bowl is mounted on top of the spindle , inside the space formed by the upper parts of the frame , the ring solid cover, the collecting cover, and frame hood . The feed and liquid discharge system , including the paring disc pump for the heavy phase, also rests on this structure. All parts in contact with the process liquid are made of stainless steel. The bowl is of the solid-ejecting disc type with hydraulic operating system. The electric motor is of the variable frequency drive type or of controlled-torque type.

Disc centrifuge operating principles

Separation takes place inside a rotating bowl. The feed is introduced to the rotating centrifuge bowl from the top via a stationary inlet pipe (1) And is accelerated in the distributor.
(2) Which was specially designed to ensure smooth acceleration of the feed liquid.
(3) The separation into liquid-liquid-solid takes place between the discs, with the oil phase moving through the disc stack to the centre. When it reaches the centre, it is discharged through hole .
(4) Leaving the distributor, the feed enters the disc stack.
(5)and ejected into the collecting frame. The water and heavy solid separated from the oil move to the periphery, and the water flows via channels in the top disc.
(6)To the paring chamber, where it is pumped out of the rotor by means of a built-in paring disc.
(7)During purification, hot water is fed into the inlet of the bowl before the process liquid is introduced. The water forms a seal around the outer edge of the top disc. The solid collect in the periphery where they are discharged intermittently via the centrifuge cyclone. The solid are discharged by means of a hydraulic system, which forces the sliding bowl bottom.
(8)to drop down at preset suitable intervals, thus opening the solid ports at the bowl periphery.
