    20" Bowl Industrial Liquid Solid Separation Centrifuge 2 Phase 50/60Hz


    20" Bowl Industrial Wastewater 2 Phase Centrifugal Separation Machine


    Discharge centrifuge for the effective separation of slurries into liquid-solid phases or liquid-liquid-solid phases, with the application of centrifugal sedimentation principle.


    A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond greater than gravity. When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phase forms a concentric inner layer. Different dam plates are used to vary the depth of the liquid the so-called pond as required. The sediment formed by the solid particles is continuously moved by the screw conveyor, which rotates at a differential speed than the bowl itself.


    The Centrifuge is for continuous separation of 3-phases systems consisting of two different liquids and one solid. Stock liquid is brought into the bowl of the centrifuge through a centrifugal pump. solids settles into outer larger by the centrifugal force. The settled sediment is pushed into the drying area at the cone of the bowl by rotary difference between spiral and bow land discharged from the outlet.


    Details of Water Treatment field


    The impurities such as glass and braids in the biochemical sludge from the sludge tank is pulverized and removed. The sludge pump sends the sludge (concentration 0.5~4% or higher) into the centrifuge, and the fully automatic flocculant dosing device adds continuously PAM flocculant solution (concentration 1~3‰) into the feed pipe through the dosing pump for flocculation in the feed pipe and in the vicinity to produce flocculus to be sent into the centrifuge. The dehydrated mud cake is discharged from the drum by a centrifuge, and transported to the outside through the screw conveyor.


    The dehydration system is widely used for oxidation ditch, AB, A/O, A2/O, SBR, MBR, anaerobic fermentation, and other processes, as well as urban domestic sewage, municipal sewage, landfill leachate, urban tap water, purified water, and some industrial wastewater of conventional sewage treatment processes. Solid-liquid separation is achieved by a high-performance DE type two-phase high-efficiency centrifuge.


    Modern water purification and sewage treatment processes, increasingly strict emission standards, and subsequent treatment of dewatered mud cakes, whether stacked, dried or incinerated, have set higher requirements for key equipment of excess sludge treatment.



    Reduce the moisture content of the sediment under the action of spiral high pressure extrusion


    High-dryness screw conveyor and drum structure

    The dehydration of solid particles relies mainly on strong centrifugal force, high-torque screw extrusion force (pushing torque), and ultra-long solid particle dehydration length. The centrifuge can generate centrifugal force exceeding thousands of G, 30 ~ 50% higher than the screw pushing torque of common centrifuges. The screw pusher torque, and the drum dehydration length is 10 ~ 20% longer than that of common centrifuges.


    High torque involute planetary gear differential

    The ultra-high pushing torque requires a high-torque involute planetary gear differential as the foundation. The differential equipped on the centrifuge features high torque, high speed, low heat generation, and excellent heat dispersion, which ensure that the centrifuge can be used for a long time and stably.


    CIP washing system

    The fully automatic control system is equipped with a CIP washing system, which can effectively solve the problem that it is not completely cleaned during the shutdown process and effectively avoid the equipment troubles caused by artificial factors.


    Humanized centrifuge configuration

    1.Spiral bearing (in the drum, concealed) lubrication technology: the lubricant is filled from the outside of the hood.


    2,The hood adopts a hinged opening structure and is equipped with a high-pressure gas strut to assist the opening.

    Variable pitch technology


    Constant torque control technology

    The constant torque control of the centrifuge is the most advanced control mode in the world. The real-time monitoring of the actual output torque of the constant torque variable frequency motor through the high-performance auxiliary inverter is compared with the set torque value, and PID is used to adjust the material pushing speed of the screw conveyor in real time. The centrifuge can achieve continuous, stable, and economic operation.
