20000L H 3 Phase Decanter Centrifuge Separators Waste Oil

High performance 3phase decanter centrifuge for waste oil water separation automatic discharging

Product description

The decanter centrifuge is a kind of machinery that carries out continuous separation of materials of density difference in suspensions by using the centrifugal sedimentation principle.

The LWS series 3phase decanter centrifuge from HUADING used for the oil water separation treatment. It can be used for the purification of waste oil, hogwash oil treatment to provide the feedstock for the production of biodiesel, it also can be used for the treatment of drilling slurry, water removal of crude oil etc.

Working principle

The bowl and screw make high speed rotation with a certain differential speed between them. The material will enter the bowl from the feed tube, under the action of centrifugal force field, the liquids of high specific weight will accumulate on the inner walls of the bowl, and be discharged through the centripetal pump or overflow plate. The liquid of low specific weight will form an inner liquid ring, stick to the surfaces of heavy liquids, and be discharged from the overflow channel. Under the action of the spiral material pusher, the solids in the materials will be continuously pushed to the taper end of the bowl and discharged from the residue outlet after going through the drying area

Main components

The main components of the decanter centrifuge include the horizontal bowl and screw, frame, hood, two drive motors, gearbox, etc.

Bowl

The bowl in a modern decanter is a cylindrical tube with a flange at either end, on which are bolted at one end the liquid discharge bowl hub, and on the other end, the cake discharge hub, or the beach followed by the cake discharge hub. The first cylindrical bowls used a filler piece in the end of the bowl to form the beach. On modern bowls, particularly the larger ones, the beach is bolted to a flange at one end of the cylindrical section, although with some overlap to provide mechanical location.

Screw

The screw conveyor (or scroll) is in the form of an Archimetlian screw, fitting inside the beach and bowl between the two end hubs, with a small clearance of less than 2 mm ratlially. It has a number of functions. Not only does it convey the solids, after they form a cake, along the cylindrical bowl section and up the beach, it also accepts the feed and accelerates it up to bowl speed.

Gearbox

The gearbox is a major component of the rotating assembly, which creates the differential speed between the bowl and the conveyor. Usually, the screw conveyor driven by a planetary gearbox turns slightly slower than the bowl.

There are two main types of gearboxes used on decanters. These are the epicyclic gearbox and the Cyclo gearbox.

Frame and hood

Usually, the frame is fabricated from steel channel or box sections. The frame needs to be a rigid support for the rotating assembly. The surfaces for the main bearing pillow blocks are accurately machined in the same plane, and in line. to ensure no end-to-end misalignment of the rotating assembly. which would cause premature bearing failure.

The frame and hood act as the link between the high g field of the rotating assembly and the stationary area around it.
