7kW - 80KW Wastewater Treatment Machine LW Decanter Centrifuge 2000rpm

Sludge Dewatering Wastewater Treatment Machine LW Decanter Centrifuge

Product Description:

Horizontal spiral centrifuge is one of our company main products. According to the requirement of the material used, we design the horizontal spiral centrifuge with one motor, two motors driving. At the same time, we design two motors separately on both sides of the machine and motors on the same place of the machine. We also develop three column horizontal spiral centrifuge, used in the separation of coal tar oil, water, slag in the industry, in petrochemical in the separation of oil, water, slag.

Main motor drive at full speed rotating drum, material put into spiral continuously by feed tube, evenly distributed to the spiral discharging port. Under centrifugal force, solid content settles to the drum wall and is pushed out cone drum slag notch by the spiral pusher. Liquid is overflow along the spiral to the drum big end. It form big end set out liquid and small end set out solid.

The process of sludge dewatering :

The sludge dewatering system consists of five parts:

(1) Sludge feeding system, (2) Flocculant dosing system, 3) Thickening and dewatering system,

(4) Mud cake delivery system, (5) Electronic control device of sets of system;

Tenchical parameters:

working principle:

Basic principle of horizontalscroll discharge centrifuges (namely decanter centrifuges): the light liquid, heavy liquid and solid (dregs) in the mixed

liquid (suspension) have different densities and are immiscible, and any two or three phases therein are then under different centrifugal forces in

the centrifugal force field, resulting in different settling velocities, then achieving thepurpose of separation, layering or settling the

solid-phase particles in the liquid.
 

After entering into the high-speed turning drum,the solid-phase particles in the mixed liquid run and settle on the drum wallunder the action of

greatest centrifugal force; the light liquid settles at the innermost  place of the drum under minimum centrifugal force; and the heavy liquid settles

in the middle (this phase exists in case of three-phase separation or does not exists in case of two phases); same as the drum’s

turning direction, a screw feeder also turns at a high speed, and a constant speed difference is generated by the differential mechanism; the solid-

phase particles settled on the drum wall are then fed by the screw feeder to the solid outletof the drum, and the light phase and heavy phase (this

phase exists in case of  three-phase separation or does not exists in case of two phases) are then separated out of different outlets.

When used for two-phase separation, the machine is called two-phase decanter centrifuge (also called horizontal scroll centrifuge), and the

machine used for three-phase separation is called three-phase decanter centrifuge. In our decanter centrifuges, the light liquid is exhausted by

gravity force, and the heavy liquid is discharged by the centrifugal force

Application:

Our centrifugal sludge dewatering machines can achieve sludge thickening, sludge dewatering as well as thickening and dewatering integration.

Thickening and dewatering of sludge arising from urban life, power plant, petrochemical refinery, coking as well as from industries.
