Shenzhou 2- Phase Decanter Machine

When you need to separate solid / liquid mixtures with high solids content, you can choose a decanter centrifuge. In contrast to chamber filter presses, these solid vortex centrifuges or decanter centrifuges operate continuously. High centrifugal forces separate finely divided solid particles from the suspension.

Our decanter centrifuges are modular in design and can be used in a wide range of industries. Centrifuges can be optimally adjusted for specific applications. Applications range from sludge dewatering to classification or wet classification to solid classification.

Its working principle is that when the suspension to be separated enters the drum of the centrifuge, the solid particles with higher density than the liquid phase will quickly settle to the inner wall of the drum under the centrifugal force of the drum. The screw conveyor inside the centrifuge pushes the solid phase deposited on the inner wall of the drum to the drying area at the small end of the drum for further dehydration, and then discharged through the slag outlet, and the separated clear liquid will flow out of the overflow weir at the large end of the drum.

Drive Type: VFD + PLC + HMI

LW 500 centrifuge is widely used by users, with large size, rotating speed of 2500-2800r/min, large processing capacity, with continuous feeding and continuous discharging. The settling speed is determined by particle size, particle shape, density difference between solids and liquids as well as their viscosity. According to the actual use, it can be divided into: clarification type, dehydration type, concentration type, separation type, classification type and extraction type, Users can choose by themself.

1. Industrial design

Whole machine set design follows concept of advanced industrial design,ensures stability, functionality and safety of whole machine.Also effectively absorbs shear force of dynamic load during operation.

2. Effectively ease resonance during rotating of bi-rotor

When centrifuge works,there is no obvious first-order and two-order resonance regions within designed speed range,meanwhile ,whole vibration intensity of bearing seat is definited within 2mm/s-4mm/s.All of this eliminates extra fatigue damage to components and assembly units from high frequency vibration during operation and sudden vibration when shut down.

3. Thoroughly eliminate phenomenon of liquid ring stalling

Phenomenon of liquid ring stalling happens during heavy duty boot or shutdown process of complete set machine,especially for LW550 and even larger models,It would makes bounce or wild shake,causes extra impact fatigue damage to main bearings,screw bearings and inner parts of rotary bowl.Fortunately ,our engineers have solved this problem thoroughly.

4. Unique technique adopt in main component work-blanks

The manufacturing methods of main component work-blanks are adopt centrifugal casting technique and overall mould-making forging technique,thoroughly avoid risks such as inter-granular corrosion and relaxation of residual stress release in welding joint.

5. Main bearing selection

We use origin bearings of international first-line brands such as SKF,FAG and so on.

6. Constant temperature detection

All fashioning components and assembly units are detected in constant temperature condition,to make sure of actual processing quality meets the requirements of designed precision accuracy.

7. Inter-change ability

Whole machine physical design and processing technique adopted in critical position,ensure all assembly units and bowls of the same centrifuge model interchangeable.It is not only easy to maintain ,but also greatly improve the reliability and safety of equipment.

8. Simplyand safely in bearing disassemblement

One layer of oil film is injected into contact surfaces between bearing and work-piece by high-pressure,during disassemblement bearing from the machine.which would fundamentally eliminate friction within different parts.As a result,it would reduce 90% of pulling force and lower the risk of damage to high-precision parts when disassemble bearing.

9. Main bearing lubrication system

There are two kinds of lubrication system for specific product models :

A thin oil lubrication

* Oil pump offers an uninterruptedly power to ensure oil works circularly;

* Jet oil lubrication constantly clean and lubricate bearings and reduce temperature;

* Oil filter system ensure lubricant’s cleanliness;

* Oil pressure energy storage system ensure lubrication pump offers an extra oil supply(the pressure is no less than 0.4Mpa) for 5-6 minutes,when power fails accidentally;

* Constant temperature system is available.

B grease lubrication

* Adopt a grease with properties of extreme pressure resistance ,oxidation resistance ,abrasion resistance,water scour

resistance,corrosion-proof and high temperature resistance.

* Optional automatic grease system fills grease on main bearing at designed hours and quantity.

10. Main bearing BH device (patent design)

There are two spare safe bearings at either end of main bearing.When machine works well,they keep certain clearance from bearing inside track to chief axis.When unexpected condition occurs,main bearing got damaged or circle center deviation causing an amplitude of vibration reaches to designed clearance,safe bearings begin to work as main bearing Meanwhile,computer automatic control system would get a feedback of abnormal vibration value on bearing position immediately then activates emergency shutdown and goes a smooth shut down.This system protects machine free from damaging and ensure production safety.

11. GSRL feeding device (potent design)

New design of internal spiral core tube has got following achieves.Without reducing centrifugal acceleration,shorten triangle belt's traction time,reduce disorder of swirling flow and extend separation time.Meanwhile increases inner working pressure of centrifuge,and restrains liquid foaming.

Screw Conveyor

The spiral feeder is made of 304 stainless steel, and the forging process is adopted , which can enhance its corrosion resistance.
BD structure, spraying hard alloy powder on the surface of the blade. The thickness is over 3mm .The spiral outlet is equipped with a replacement hard alloy sleeve, which greatly prolongs the service life of the machine blade. Because of this technology,the maintenance cost of the machine is greatly reduced. Other parts in contact with the material are 304 stainless steel.

Drum

The drum is cast by 304 stainless steel in centrifugal casting, the forging process is adopted , which can enhance its corrosion resistance, The replaceable alloy sleeve is installed in the solid state outlet, so that the mother material of the drum's outlet is not worn, and the wear-resistant bar is installed in the drum to make the drum inside not worn.

PLC Control Panel

The electrical control adopts the double conversion auto control system, which can display the parameters such as frequency, rotation speed, differential speed and current of operating major and auxiliary electrical engine.

Eletrical Components:
SIEMENS/Schneider/ABB

High Degree of Automation

Shenzhou decanter differential speed automatic control technology can automatically adjust the screw conveyor’s differential speed, to prevent overload and blockage. The complete machine is equipped with bearing temperature sensor and vibration sensor, and is provided with alarms for main motor overload, differential over torque, low differential speed, etc. Meanwhile, its supporting frequency conversion (flameproof) control cabinet can realize automatic start and stop with one key.

Bearing

All bearings adopt original imported NSK/SKF bearings. The electric control box is made of electrical elements of famous brands such as Siemens and Schneider.
