LWS Three-phase Oilfield Drilling Centrifuge
Product Description
Separation takes place in a horizontal bowl equipped with a scroll conveyor. The process material is fed into the bowl through a stationary inlet tube and is smoothly accelerated in the accelerate chamber. Centrifugal forces cause instant sedimentation of the solids on the wall of the bowl. The conveyor rotates in the same direction as the bowl, but at a different speed, thus moving the solids towards the conical end of the bowl.
LWS series three phase decant centrifuge is used for solid-liquid-liquid separation, namely one kind of solid phase (with largest specific gravity ) and two kind of immiscible liquid phase with different density. The conveyor rotates in the same direction as the bowl, but at a different speed, the material is fed into the bowl through a stationary feed pipe. Centrifugal forces cause instant sedimentation of the solids on the wall of the bowl, while two liquid phases forming light liquid phase layer and heavy liquid phase layer. Scroll conveys the solids towards the conical end of the bow, and out of centrifuge from solid discharge port. The light liquid phase then is discharged out continuously through the overflow port at the large end of the bowl, and the heavy liquid phase will be discharged out through the centrifugal pump large end of the bowl, thus realizing the three-phase separation.
Main applications
LW series decanter centrifuge is a horizontal centrifuge with continuous feeding and continuous discharging. It has two-phase (solid-liquid) separation and three-phase (solid-liquid-liquid) separation.
Applications:
- Industrial and municipal wastewater treatment
- Oil & gas drilling mud/fluid control
- Washing, classification and dewatering of amylum and starch
- Mycelium separation from zymotic fluid of antibiotic
- Dewatering of soybean and wheat protein
- Dewatering of fish power and fish meet
- Dewatering of grains
- Clarification and extraction of fruit juice
- Clarification and purification for animal and vegetable oil
- Production and extraction of olive oil, palm oil, avocado oil
- Separation and purification for coal tar
- Grading of kaolin and graphite
- Classification and dewatering for dyestuff and pigment
- Float wash of extractive coal and dewatering of coal mud
- Classification and dewatering for minerals
Main features
◇ Vertical base design and symmetrical arrangement of motor and
bowl assembly, that ensures stable operation and less vibration.
◇ Main parts such as the bowl and conveyor are made of
corrosion-resistant stainless steel or duplex steel, offering high
maximum bowl speed and high centrifugal force.
◇ Dual motor drive makes bowl speed and conveyor speed adjustable.
◇ Screw conveyor flights tiled or lined with ceramic, tungsten
carbide, or other hard alloys.
◇ Optionla planetary gearbox and hydraulic gearbox, offering wide
range of differential speed adjustment.
◇ Multiple safety protection: bowl speed and differential speed
detection, over-vibration protection, motor overload and overheat
protection, bearing temperature monitoring, conveyor torque
protection and gas-tight explosion-proof protection.
◇ JG type rubber vibration isolator, no need of anchor bolts.
Parameters
Hydraulic scroll driving system
The hydraulic conveyor driving is a closed driving system, including the centrifuge bowl and conveyor. It is independent from the bowl driving. The hydraulic conveyor driving is different from other mechanical conveyor driving system which relies on bowl rotating to generate differential speed. The hydraulic driving device is directly mounted on the conveyor assembly, and is driven by hydraulic pump aggregate. Therefore it is independent from the bowl driving system.
Operating principle
The hydraulic conveyor gearbox is connected with the bowl of the decanter centrifuge, both of them rotates in high speed. The spline shaft on the gearbox rotor is connected with the conveyor, and rotates in different speed driven by the high pressure oil, that's we call the differential speed. The conveyor gearbox is connected with the hydraulic pump by flexible hose, so there is no need of gearbox between the bowl and conveyor. Conveyor torque gives pressure to the hydraulic system. With the action of such pressure, the different speed can by adjusted by adjusting the oil supply and flow rate.
Main features
◇ No gear driving device required
◇ No damage to the parts due to overload
◇ Free of torque vibration (fluttering)
◇ Direct readable torque and differential speed △n
◇ The independent from bowl speed
◇ Minimum moisture content of sludge
◇ High clarification of liquid phase
◇ Power for solid conveying varying from solid loads
◇ Dewatering varying from changes in △n
◇ “Constant” moisture content of sludge
◇ Non-sensitive to feeding quantity, minimize blockage
◇ Safety pin design ensuring safe operation
