Product Description

Product Description

Industrial 3-phase decanter centrifuge
In traditional separation processes, solids are separated from one or more liquids of different densities. However, the two are often mixed together. The decanter centrifuge is definitely a very good solution. It can continuously separate three phases (solid liquid liquid) in one step. It plays a convincing role in processes such as oily sludge treatment, starch production, and oil extraction.
Three phase separation provides users with more advantages: by combining processing steps, additional separation steps can be eliminated, thereby saving a lot of costs. In addition to having high separation accuracy, our decanter centrifuge is also flexible to use. It can be adjusted at any time according to changing feed conditions.

Working principle

The drum and the spiral feeder rotate in the same direction but with a certain speed difference; the material is led into the feeding spiral inner cylinder via the feeding pipe and, after speeding pipe and, after speeding up, enters the drum; under the action of the centrifugal force field, the relatively heavier solid-phase material deposits on the drum wall forming the residue layer; the solid-phase residue is continuously pushed by the spiral feeder to the conic end of the drum and, after dehydration in the drying area, is discharged out of the machine.The machine is capable of continuous feeding, separating, dehydrating and discharging under full-speed running.

Our Advantages

1. Industrial design
The whole machine set design follows the concept of advanced industrial design, ensuring the whole machine's stability, functionality, and safety. Also effectively absorbs the shear force of dynamic load during operation.
 
 2. Effectively ease resonance during the rotating of bi-rotor
When the centrifuge works, there are no obvious first-order and two-order resonance regions within the designed speed range, meanwhile, the whole vibration intensity of the bearing seat is definitely 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 the phenomenon of liquid ring stalling
The phenomenon of liquid ring stalling happens during the heavy-duty boot or shutdown process of a complete set machine, especially for LW550 and even larger models, It would make a bounce or wild shake, causing extra impact fatigue damage to main bearings, screw bearings, and inner parts of the rotary bowl. Fortunately, our engineers have solved this problem thoroughly.

 4. Unique technique adopts in main component work-blanks 
The manufacturing methods of main component work blanks adopt the centrifugal casting technique and overall mold-making forging technique, thoroughly avoiding risks such as intergranular corrosion and relaxation of residual stress release in welding joints.
 
 5. Main bearing electrical components selection
We use the origin bearings of international first-line brands such as S-K-F, F-A-G, etc. Electrical components mainly adopt ABB and Siemens
 
 6. Constant temperature detection
All fashioning components and assembly units are detected in constant temperature conditions to ensure that 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 are interchangeable. It is not only easy to maintain, but also greatly improves the reliability and safety of the equipment.
 
 8. Simply and safely in bearing disassemblement
One layer of oil film is injected into contact surfaces between the bearing and work-piece by high-
pressure, during the disassemblement bearing from the machine.which would fundamentally eliminate friction within different parts. As a result, it would reduce 90% of the pulling force and lower the risk of damage to high-precision parts when disassembling the bearings.

9. Automatic main bearing lubrication system
Thin oil lubrication
 * Oil pump offers uninterrupted power to ensure oil works circularly;
 * Jet oil lubrication constantly cleans and lubricates bearings and reduces temperature;
 * Oil filter system ensures 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.
 * Adopt a grease with properties of extreme pressure resistance, oxidation resistance, abrasion resistance, water scour resistance,corrosion-proof, and high-temperature resistance.
 * Automatic grease system fills grease on the main bearing at designed hours and quantity.

 10.  Main bearing BH device (patent design)
There are two spare safe bearings at either end of the main bearing. When the machine works well, they keep a certain clearance from the bearing inside the track to the chief axis. When an unexpected condition occurs, the main bearing getting damaged or circle center deviation causing an amplitude of vibration reaches to designed clearance, safe bearings begin to work as the main bearing Meanwhile, the computer's automatic control system would get feedback of abnormal vibration values on the bearing position immediately then activates emergency shutdown and goes a smooth shut down. This system protects the machine free from damage and ensures production safety.
 
 11.  GSRL feeding device (potent design)
The new design of the internal spiral core tube has got the following achieves. Without reducing centrifugal acceleration, shorten the triangle belt's traction time, reduce disorder of swirling flow, and extend separation time. Meanwhile increases the inner working pressure of the centrifuge, and restrains liquid from foaming
