Product Description

 

Product Description

 Sludge is produced when drinking water is produced from raw water.   Disposal of this settled sludge is a challenge for water plants.   Transportation and landfill costs can be high, adding to the overall cost of water treatment.

This is where the decanter centrifuge comes in handy.  Which provides an optimized solution for the dewatering and volume reduction of sludge in water plants.   Water plant sludge can be effectively dehydrated, thereby reducing the amount of sludge.   This reduces waste disposal costs associated with drinking water extraction.
The most important goal of dehydration is to minimize the amount of sewage sludge to the greatest extent possible. Because every 10% increase in dry matter in sludge reduces the cost of sludge cleaning SHENZHOU centrifuge can reduce operating costs and energy consumption, and achieve higher dry matter content. When concentrating, high separation and low polymer demand are particularly important. Both have reduced the burden of subsequent treatment and improved the overall efficiency of sewage treatment plants. SHENZHOU centrifuge used for sludge concentration concentrates the dry matter content of sewage sludge to a few percent. By using our decanter centrifuge, optimal sludge concentration can also be achieved with the aid of starch polymer based flocculants. Starch polymers are largely biodegradable, and very good values can be obtained using our decanter centrifuge. When treating drinking water, water plant sludge is generated. In order to reduce the transportation and landfill costs of the generated sludge, a decanter centrifuge can be used. It increases the dry matter content while reducing the demand for polymers.



Operating principle:
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.

Our Advantages

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 electrical components selection
We use origin bearings of international first-line brands such as S-K-F,F-A-G and so on.Electrical components mainly adopt ABB and Siemens

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.
