How does a Disc Stack Centrifuge Work ?

If you want to separate or clarify more fine particles of liquid materials with higher speed, such as algae extraction, beer clarification, protein extraction, etc., the horizontal screw sedimentation centrifuge has reached its performance limit, then you can choose a high speed disc stack centrifuge.

Disc centrifuge is a kind of industrial centrifuge used to clarify and separate liquids. It is also a kind of vertical centrifuge.

It is named disc centrifuge because there are a group of disc-shaped parts (discs) in its bowl. Its bowl is installed on the upper end of the vertical shaft, and the drive device is driven by the motor, and the power is transmitted to the main shaft of the bowl smoothly through the belt. At the same time, the frequency converter is used to control the motor, and the speed can be adjusted according to the corresponding material conditions.

The running speed of the disc centrifuge can be quickly increased, and the speed can be quickly and smoothly re-accelerated after the solids is discharged until the maximum speed is reached.

At the same time, the disc centrifuge is also equipped with PLC control panel, efficient lubrication circulation system and CIP automatic cleaning system; If it is in the food and pharmaceutical industry, the high-quality duplex stainless steel conforming to the hygienic design standard should be selected. If there is explosion risk in the process of material treatment, inert gas device can be selected to prevent combustible gas leakage and meet the requirements of explosion-proof standard.

Disc centrifuge can be used for two-phase and three-phase separation, as clarification separation disc centrifuge (two-phase separator), which can discharge the finest solid particles from the liquid. As a disc centrifuge (three-phase separator), it can separate the liquid phase with different density and dissolve the solid at the same time.

Working Principle of Disc Centrifuge:

There is a small gap between discs. The suspension (or emulsion) enters the inside of the bowl through the feed pipe in the center of the bowl, and the material is slowly accelerated in the distribution room until it is synchronized with the bowl speed.

When the suspension (or emulsion) flows through the gap between the discs, the solid particles settled on the discs under the action of centrifugal force to form sediment.

The sediment slides along the surface of the disc and gets away from the disc, and accumulates in the solids collection cavity, which has the largest diameter in the bowl. After that, discharged or shutdown to clear it, the sediment is removed, and the separated liquid is discharged from the outlet of the bowl.

The function of the disc is to shorten the settling distance of the solid particles and expand the settling area of the bowl. The production capacity of the separator is greatly improved due to the installation of the disc in the bowl. The solids accumulated in the bowl are removed manually after the separator is shut down, or discharged from the bowl through the solids discharge mechanism without shutting down.
