Waste Oil Treatment Decanter Centrifuge

The recovery and treatment of waste oil mainly involves the following fields:

Waste residue and oil-water mixture at the bottom of the oil storage tank

Oil residue and waste oil from refineries

Oil stains in the sewage pool

Waste oil-water mixture from ships

API oil-water separation and oil pollution treatment

Lubricants and greases generated by industrial lubrication production systems

Advantages of SHENZHOU waste oil treatment centrifuge:

Customizable products according to different customer needs

The industry and equipment for oil sludge recovery and treatment may vary depending on the source and composition of the customer's waste oil, as well as the required product quality after treatment. But typical sludge treatment involves the following processes:

Separate the solid sludge from the oil sludge

Reduce viscosity by adding chemicals and heating

Demulsification, by making a mixture of oil, water, and sludge that was originally bound together easier to separate by centrifugation under the action of demulsifiers

Improving the separation efficiency of centrifuges by adding polymers

The advantages of our product

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
