Material performance and operation requirements of three-phase separation decanter centrifuge

- Aug 15, 2018-

The mud-water mixture of the three-phase separation decanter centrifuge enters the drum through the feeding pipe and the spiral discharge port. Under the centrifugal force generated by the high-speed rotation of the main machine, the solid phase particles with a large specific gravity are deposited on the inner wall of the drum, The spiral blade for the relative movement of the drum continuously scrapes off the solid phase particles deposited on the inner wall of the drum and pushes out the slag discharge port, and the separated supernatant liquid flows out of the drum through the jaw opening.

The relative movement between the screw and the drum of the three-phase separation decanter centrifuge is realized by the differential, the outer casing of the differential is connected with the drum, the output shaft and the spiral connection, the input shaft and the auxiliary motor Join. The main motor drives the rotating drum to rotate, which also drives the rotation of the differential housing. Since the input shaft is connected with the auxiliary motor, the secondary motor generates a braking torque, thereby driving the planetary gear to operate according to the designed transmission relationship, and according to a certain The proportional relationship transfers the torque to the helix, enabling continuous separation of the material by the horizontal screw sedimentation centrifuge.

The three-phase separation decanter centrifuge can reasonably select the relevant parameters of the centrifuge according to the material properties of the suspension, the liquid phase and solid phase requirements after separation, and the processing capacity. As the drum speed increases, The separation factor rises, the separation effect increases, the differential speed between the spiral and the drum increases, and the processing capacity increases. However, the vibration and noise of the centrifuge also increase, and the service life will decrease, generally meeting Under the premise of separation requirements, it is very important to choose the appropriate speed.
