Professional Waste Oil Water Separator/Disc Stack Centrifuge

Working Principle Of  Disc Stack Centrifuge Separator

This kind of centrifuge is for liquid-solid separation and filtration. It is designed with innovative, cost-effective features and integrated processing advantages

To separate, delaminate or sedimentate the fine solid particles in liquid by getting different sedimentation speeds under centrifugal force field for light/heavy phase or solid phase that are of different densities and not solvable each other in liquid mixture (turbid liquid).

The material [turbid liquid] enters drum through feed pipe, by the powerful centrifugal force field, the material passes the separating compartment of a set of disc bunches, the supernate is discharged under pressure by a centripetal pump installed inside the bowl; the solid sediment accumulates at the sediment area and will be discharged automatically with an automatic self-cleaning style unit.

This kind of centrifuge can perform a wide variety of functions for liquid-solid clarification, including:

1)Clarification of raw and depectinized fruit juices; cloudy juices and other beverages

2)Clarification of high-solids susupension.

3)Refining of algae

4)Extracting of pigment

5)Purifying paint, dye, various resin
6)Purifying for Hydraulic, Diesel fuel, Diesel lubricating, heavy fuel, Turbine lubricating, Transformer, Cutting and Grinding oils etc

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(4). Leaving the distributor, the feed enters the disc stack(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 (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
