Product Description

 

The full name of the decanter centrifuge is the horizontal screw decanter centrifuge, which is a widely used equipment in the field of industrial solid-liquid separation. According to the characteristics of different materials in different industries, SHENZHOU decanter centrifuge is divided into dewatering, separation, and clarifying decanter centrifuge. With centripetal pump technology, SHENZHOU decanter centrifuge can also realize the 3-phase separation of liquid, liquid, and solids.

Series/Type	Beach Angle	Centrifuge Applicable Material Features
LWT Series Dewatering Type	8.5°	LWT series dewatering type decanter centrifuge is usually used to remove liquid from solid phase materials. It is designed for easy separation material include large particle size, high density difference of solid and liquid, low viscosity, high concentration, high treatment capacity and higher dryness than clarity. The materials like sludge or wastewater containing fine particles usually need to be added with flocculants to gather the fine particles condensed into large ones, and then dewatered with T series decanter centrifuge.
LWY Series Separation Type	15°	LWY series separation type decanter centrifuge combines the advantages of T series dewatering centrifuge and C series clarifying centrifuge. It is designed not only for the clarity of liquid phase after separation, but also the dryness of solid phase. Y Series separation decanter centrifuge is especially suitable for fine soft material separation. It is usually used in soft materials which are difficult to separate. It suits for material of small particles, small density difference in solid-liquid, large viscosity and small concentration.
LWC Series Clarifying Type	20°	LWC series clarifying type decanter centrifuge is generally used for materials that are difficult to separate, have small particles, small solid-liquid density differences, moderate viscosity, moderate concentration, and require high clarity of clear liquid.
LWS Series 3-Phase Type	According to material	The design of 3-Phase horizontal decanter centrifuge is mainly used for solid-liquid-liquid 3-phase separation. It is required that the solid phase is heavier than the liquid phase, the two liquid phases are Immiscible with different densities.

As a leading manufacturer of decanter centrifuges, SHENZHOU pays attention to product quality and considers the long-term benefits of users. In the selection of raw materials for decanter centrifuges, high-quality centrifugal casting or forging stainless steel materials are used, and for wearing parts, hard alloy protection is used. SHENZHOU high-end CNC lathes, CNC centers, and CNC gantry milling machines can better ensure the machining accuracy of centrifuge parts. In terms of the dynamic balance of the decanter centrifuge, in addition to the ordinary low and medium speed dynamic balance, also applies a high speed dynamic balance process, which can dynamically balance the centrifuge screw and bowl at the actual working speed of the centrifuge. In terms of market applications, SHENZHOU decanter centrifuges are widely used in the industry, and the products are exported to more than 60 countries and regions in the world, and have won high praise from customers.

 

 is mainly designed for Solid-liquid-liquid three-phase separation of materials.With our over 10 years of experience in the separation industry, it is the most advanced type machine for 3 phase separation. It is designed for 24 hours continuous and smooth operation throughout the day. It is mainly composed of driving system, decanter bowl, screw conveyor inside the bowl, cover box, skid and VFD control panel.

To ensure that the separation process can take place, the solid phase must be the specifically heaviest phase and the two liquid phases must have different densities.The main difference between the 2 phase decanter and 3 phase decanter is that the 3 phase decanter not only separate the solids but also separate two phase of the liquid.

 3 phase decanter is widely used for oil , water, solids separation industry.
 

3 PHASE DECANTER WORKING PRINCIPLE
The three-phase decanter centrifuge operation is based on the principle of sedimentation, that is, solid particles with specific liquid weight precipitate in a predetermined time. This principle can also be applied to two immiscible liquids with different specific gravity. When the material enters the high-speed rotating drum, the material rotates synchronously with the drum. Because of the different specific gravity, the centrifugal force is different. The solid particles with the larger specific gravity are subjected to the greatest centrifugal force, followed by the heavy phase liquid (such as water) and the light phase liquid (such as oil). So the centrifugal force is becoming less from outside to inside according to the magnitude of centrifugal force. A concentric solid layer and two liquid layers are formed. Solids are pushed out by the screw conveyor, and liquids are removed from their respective nozzles. Therefore, the application of three-phase decanter centrifuge can not only separate the solid in the material, but also separate the two-phase liquid with different specific gravity in the material, that is, Solid-liquid-liquid separation can be achieved.

The machine could deal with the material which range of concentration is large, small size which widely distributing. Solid particles are less 0.5mm as rigid particles, and less than 10mm as non-rigid particles, the machine can be effectively treated.

 

 

Taking advantage of the principle that the light liquid, heavy liquid and solid phase, with different density and mutually insoluble in the mixed liquid, gain different sedimentation speed in the centrifugal force field or gravity force field, separating stratification or causing the solid particles in the liquid to deposit can be achieved.
In the gravity force field or centrifugal force field, the light liquid phase, the heavy liquid phase and the solid phase with different density and mutually insoluble in the mixed liquid, respectively gain different sedimentation speed, and thus separate and stratify. In the gravity force field it is called gravity separation, while in the centrifugal force field it is called centrifugal separation.

 

 

 

 

On account of difference in density, the mixed liquid in the container, after a period of time, is gradually divided into 2 layers.
The heavy phase particle of the mixed liquid deposits to the bottom of the container, while the light phase one suspends to the upper surface. A rather distinctive dividing plane forms between the light and heavy phases. The separation speed is affected by the difference in density between the light and heavy phases that make up the mixed liquid. The larger the difference in density is, the faster the separation speed will be.

 

 

 

 

When the container filled with mixed liquid rotates at high speed around its own axis, due to the difference in density between the two phases making up the mixed liquid, they bear different centrifugal force. Under the action of a larger centrifugal force, the heavy phase in the mixed liquid quickly subsides on the inner wall of the drum, while the light phase slowly adhere close to the surface of heavy phase. The faster the container rotates, the larger the difference in centrifugal force borne by the light and heavy phases that make up the mixed liquid, and the faster the separation speed. When the container is equipped with such parts as feeding mainly comprised of such parts as drum, helical propeller, planet gear differential mechanism, pedestal, hood and lubricating system
