Operation requirements and settlement principle of drilling mud sedimentation centrifuge

- Aug 25, 2018-

The drilling mud sedimentation centrifuge is a new type of equipment. In the process of operation, the working principle is mainly to use the difference in solid-liquid specific gravity. To a certain extent, it mainly relies on the centrifugal force field to expand it several thousand times. The solid phase is Under the action of centrifugal force, it will be settled, so that solid-liquid separation can be achieved, and the body can be separately discharged under the action of a special mechanism.

When the drilling mud sedimentation centrifuge is running, when the filtration resistance is too large due to the solid particles clogging the filter medium in the centrifugal filtration, or the fine particles are excessively lost, the filter centrifuge cannot achieve the ideal separation effect. Centrifuges have the advantage of a filter that is incomparable. By using the principle of centrifugal sedimentation, solid phase particles having a small particle size can be separated from the liquid phase.

The drilling mud sedimentation centrifuge is added to the suspension in the drum during operation to form an annular liquid layer under the action of centrifugal force, wherein the solid particles will settle on the drum wall to form sediment. The clarified liquid is discharged through a drum overflow or a pipette, and is referred to as a separating liquid. At the end of the separation, the sediment is discharged manually or mechanically. During the process of sedimentation to the drum wall, the solid particles also move axially with the liquid flow. When the feed amount is too large, the liquid flows to the overflow port, and the fine particles that have not settled to the drum wall are discharged with the separation liquid. Rotate the drum to make the separation liquid turbid.
