Structure and working principle of sludge dewatering decanter centrifuge

- Mar 19, 2018-

Speaking of the structure of sludge dewatering decanter centrifuges, the major ones are the drums, screw conveyors, differentials, and main bearings, followed by a base frame, a liquid-solid collection chamber, a cover, and a motor drive. Device, inverter and other components.


The use of sludge dewatering decanter centrifuges is for sedimentation sludge from sludge thickening tank, after crushing by sludge cutting machine, because the sludge feed pump conveys, after measuring by electromagnetic flowmeter, it will also flocculate The prepared pharmaceutical liquids delivered by the dosing system are directly combined and mixed into the dehydrator equipment; the sludge is separated into solid/liquid two phases after being separated by a dehydrator, and the liquid phase (clarified liquid or separated liquid) is discharged directly. Or it is sent back to the sedimentation tank and the solid phase (dewatered sludge) is also discharged from the screw conveyor to the transport vehicle.


Sludge dewatering decanter centrifuges are used in the automatic dosing system of flocculants. Powdered flocculants are also added from hoppers (material feeders), and because the automatic powder feeding device is added to the preparation tank (colloidal flocculant After adding the metering pump directly to the preparation tank).


At the same time, the tap water must flow directly into the preparation tank through the flowmeter and be automatically formulated into a solution with a certain concentration (about 0.08-0.15%); the solution from the preparation tank flows into the storage tank because the dosing screw After the pump is pumped, it is measured by an electromagnetic flowmeter, mixed with a sludge from a sludge thickening tank through a helium tube (or a static mixer), and centrifugal force brought about by the high-speed rotation of the dewatering dewatering decanter centrifuge.


At this time, the sludge dewatering decanter centrifuge will cause the dense material (solid phase) in the suspension into the drum, and then, after being subjected to the action of the centrifugal force and the centrifugal pressure, it will settle, separate, and enter together. Sludge dewatering sludge dewatering centrifuge, and its actual sludge dewatering effect will also appear better.
