Product Description

Product Description

 ?

LWS520 three-phase centrifuge can continuously feed, separate and discharge at full speed. It has the characteristics of compact structure, easy sealing, stable operation, low noise, large processing capacity, low energy consumption, high degree of automation, low labor intensity, convenient operation and maintenance, wide application range and so on. For some materials that are difficult to separate, in addition to taking corresponding adjustment measures for the separat-ed materials themselves, the centrifuge can also be adjusted and improved accordingly:
 

1. Increase the length diameter ratio;

2. Adjust the rotating speed of the drum;

3. Adjust the differential speed between the drum and the discharge screw;

4. Change the half cone angle of the drum cone section and adopt multi cone angle sorew;

5. Adjust the overflow radius of the liquid phase outlet;

6. Change the number of screw heads and screw lifting angle of discharge screw;

7. Add BD plate structure;

Structure and Working Principle

 

In the three-phase horizontal screw centrifuge, the materials to be separated enter the acceleration chamber of the screw pusher through the feed pipe and then enter the inner wall of the rotating drum at high speed. Due to the different specific gravity of light liquid phase heavy liquid phase insoluble solid phase in the materials, the centrifugal force on the three-phase materials is different, and the insoluble solid phase is settled to the inner wall (outermost) due to the largest centrifuge with the largest specific gravity, Due to the minimum centrifugal force, the light liquid phase is settled farthest (outermost) from the inner wall of the drum. The heavy liquid phase is in the middle. The insoluble solid phase is discharged from the solid phase outlet through the screw pusher with relative differential speed with the drum. The light and heavy liquid phases are separated by different structures in the machine. The heavy liquid phase is discharged through the centripetal pump and the light liquid phase is discharged by gravity, so as to achieve the purpose of three-phase separation of materials. The light and heavy liquid phases of our three-phase horizontal screw centrifuges are discharged by gravity and centrifugal force respectively, so as to effectively avoid the incomplete separation of materials caused by the mixing of materials. When working, the ordinary three-phase horizontal screw centrifuges often cause incomplete separation due to the unstable components of light and heavy liquid phases, Our three-phase horizontal screw centrifuge can adjust the interface of light and heavy liquid phases according to the changes of material components, so as to achieve the ideal separation effect.

At present, three-phase horizontal screw centrifuges are widely used in chemical industry, light industry, medicine, food, papermaking, mining and other industries. And coal tar industry; Petrochemical industry; Fishing powder industry, swill oil industry, electrolytic copper industry, and the separation of oil, water and slag from waste residues in slaughterhouses.

Material concentration: the material is required to have good fluidity, subject to not affecting the feed. The weight percentage of mixed liquid and solid concentration is generally ≤ 20% (good fluidity, which can be relaxed appropriately).

Material temperature: the allowable material temperature of this centrifuge is ≤ 900C.

 

What's a decanter centrifuge ?
 

The horizontal spiral centrifuge, also known as a horizontal screw centrifuge, is a type of centrifuge that utilizes a rotating screw conveyor mechanism to separate solid particles or liquid-liquid mixtures based on their density. The centrifuge operates by subjecting the mixture to high centrifugal force, causing the denser components to move towards the outer edge of centrifuge while the lighter components stay towards the center. 

 

It consists of a column cone, spiral discharge device, differential system, bearing seat, base, cover, main and auxiliary motors,and electrical system. It is capable of separating materials ranging from 0.002 to 5um. This tricanter centrifuge is commonly used in various industries such as chemical, pharmaceutical, food processing, and wastewater treatment.  

 

It offers advantages such as 24 hours continuous operation, high separation efficiency, and the ability to handle large volumes of feed material. Horizontal spiral centrifuges are particularly effective separating fine particles or emulsions with a narrow density difference. 

 

The LWS520 centrifuge allows for adjustable parameters to optimize the separation process. Parameters such as rotation speed, differential speed, and liquid level can be adjusted to suit the specific characteristics of the oil being processed. Fine-tuning these parameters improves the separation efficiency and product quality.

 

How does Tri-phase Decanter Centrifuge Work ?

 

 

Three phase Centrifuge working principle

 

Three-phase centrifuge is that two liquid phases and one solid phase enter the centrifuge and expand it thousands of times by relying on the centrifugal force field. The solid phase is settled under the action of centrifugal force, and the two liquid phases are also stratified, so as to realize Solid-liquid-liquid 3-phase separation and discharge them from the body under the action of special mechanism. The whole feeding and separation process is continuous, closed and automatic. (solid-liqui-liquid separation)

Spiral Feeder

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.
