The structure of the decanter centrifuge
Decanter centrifuge is an equipment with low energy consumption, stable function and good separation effect. Widely used in the chemical, food, salt, mining, pharmaceutical and other industries (for the separation of dozens of materials, because of the successful application experience, you can communicate with technicians when selecting models to obtain more detailed materials). In the separation process, the feeding, dewatering, washing, unloading and other processes are continuously completed, and the production efficiency and automation are high. It is an advanced separation equipment.
Because of its separation principle and structural characteristics, it is also highly specific to materials. Material analysis and corresponding experiments should be carried out when selecting models to confirm its applicability and separation function.
The solid particles with a larger specific gravity of the decanter centrifuge are deposited on the inner wall of the drum. The decanter centrifuge is a kind of mud-water mixture that enters the drum through the feed pipe and the screw discharge port. Under the action of centrifugal force generated by the high-speed rotation of the host. The spiral blades moving relative to the drum continuously scrape the solid particles deposited on the inner wall of the drum and push them out of the slag discharge port, and the separated clear liquid flows out of the drum machine through the weir plate opening.
The working principle of the decanter centrifuge is that the mud-water mixture enters the drum through the feed pipe and the screw discharge port. Under the action of the centrifugal force generated by the high-speed rotation of the main engine, solid particles with a larger specific gravity are deposited on the inner wall of the drum. Such machinery and equipment include horizontal spiral unloading and sedimentation centrifuges and vertical sedimentation centrifuges and so on.
The spiral blades of the decanter centrifuge and the rotating drum move relatively to each other to continuously scrape the solid particles deposited on the inner wall of the rotating drum and push them out of the slag discharge port. The separated clear liquid flows out of the drum through the opening of the weir plate. The relative movement between the screw and the drum is completed by the differential, the shell of the differential is connected with the drum, the output shaft is connected with the screw, and the input shaft is connected with the auxiliary motor. When the main motor rotates the drum, it also rotates the differential housing. Because the input shaft is connected to the auxiliary motor, the auxiliary motor generates a braking torque, and then drives the planetary gear to work according to the designed transmission connection, and press A certain proportion of contact transfers the torque to the screw, which completes the continuous separation of materials by the decanter centrifuge.
