Product Description

Dewatering Decanter Centrifuge for the Management of Wastewater Sewage Sludge and Industrial Liquid and Solids Separation

Centrifuge Innovation and Non-Stop Optimization are Key to Our Success. The Shenzhou line-up of treatment equipment for biosolids, designed to deliver the highest quality for superior performance and the lowest cost-of-ownership to our customers around the world.

Technology

Dewatering Decanter Centrifuge for the Management of Wastewater Sewage Sludge and Industrial Liquid and Solids Separation

A decanter centrifuge consists of a rotating bowl with an independent rotating scroll inside. The solids and the liquid (sludge/slurry), which are subject for dewatering, are fed through an inlet pipe into a mixing chamber in the scroll where polymer is supplied to get a flocculation and provide a better dewatering performance. The slurry is thrown out to the bowl´s outer walls and are transported out from the decanter through the scroll while the centrate water is pressed back to the centrate outlet. The water level in the bowl is regulated, and the nature of the slurry determines what water level that is appropriate. The drum and the scroll rotate independently up to 3600 RPM depending on model and type of slurry.

Operating principle:

Dewatering Decanter Centrifuge for the Management of Wastewater Sewage Sludge and Industrial Liquid and Solids Separation
The purpose of separation is to separate out substances with different mass ratios from mixed fluid.Separation forms included solid-liquid separation,liquid-liquid separation and liquid-liquid-solid separation.
When mixed fluid enters rotating bowl of centrifuge through feed tube ,solids with larger density would rapidly deposit on inner wall of the bowl,forced by centrifugal acceleration.Then spiral pusher pushed deposited solids to taper end of the bowl,and discharges them out of centrifuge from residual outlet.Meanwhile ,liquid phase with smaller density forms a liquid ring layer and discharges from bowl through overflow port,the bowl and spiral pusher run at a high speed simultaneously ,for there exists speed discrepancy,deposited solids on the wall of bowl could be conveyed to residue outlet by spiral pusher.This separation process carry out continuously.

Separation technique
Feeding-gravitational separation-liquid discharge-sediment discharge.
Separation effect factors Centrifuging factor ,length to diameter ratio of cavity ,depth of fluid pool.
Field control
Bowl rotating speed ,rotative speed difference,between,spiral pusher and bowl depth of liquid pool.

In the production of surimi, the shredded fish fillets will go through two to three cleaning processes. In this process, impurities such as blood and fat are washed away. The washing water is usually roughly filtered through a rotating sieve. In traditional surimi production, the dehydration of fish meat is done by a screw press. The meat is then treated with antifreeze and deep-frozen. This surimi production method has many disadvantages: Different washing stages and screw pressing process lead to a large amount of fish fiber loss 1.Need a lot of cleaning water 2.Huge space requirement 3.The raw material is easy to be infected with bacteria The Shenzhou decanter centrifuge can solve all the above problems. In the production of surimi, the decanter centrifuge can not only recover the fish meat from the washing water, but also replace the screw press. In this way, the output rate of the surimi production process can be significantly improved.

Main technical features

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
Dewatering Decanter Centrifuge for the Management of Wastewater Sewage Sludge and Industrial Liquid and Solids Separation
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
Dewatering Decanter Centrifuge for the Management of Wastewater Sewage Sludge and Industrial Liquid and Solids Separation
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.
