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.
Eletrical Components: SIEMENS/Schn/ABB

Main Characteristics

1. The large content of solid will speed up the wearing of the centrifuge parts touching sludge. To solve this problem, Shenzhou adopts the tungsten carbide material at the wearing parts like screw blade, solids discharge port and sludge distribution port.
This kind of protection will extend the services life of the machine.

2. The power consumption is an issue of great concern to users. For better pushing out the solid cake, the decanter centrifuge need to be equipped with motors that with sufficient torque. To reduce the power consumption during the running of the decanter, Shenzhou designed 2 units driving motors as common DC bus mode, which makes the back motor a generator during normal running condition.

Shenzhou equipped VFD control panel to the dewatering decanter centrifuge. According to different sludge condition and treatment target, the user can set up the running speed and differential speed of the machine. All setting can be done on the HMI touch screen. By adding the temperature and vibration sensor and installing the signal receiving device in the control panel. The VFD panel can display the running condition and monitor the machine. In the VFP control panel, SZ normally installs VFD and other electrical components for feeding pump control.
In the sludge dewatering package, the decanter centrifuge is the core equipment, while it is always equipped with sludge feeding pump, polymer dosing unit and solid cake screw conveyor to make an integrated package.
 

Characteristics Of Suspension Materials

The larger the solid particles in the material, the easier it is to separate. The size of the solid particles varies, and the
final separation effect is determined by the small particle solid phase. This machine can generally remove solid particles above 5 um. When the solid particles are especially small, they will not settle and separate out, but will be discharged together with the clarified liquid; The final separation effect depends on the distribution of solid particles in the material. The more particles above 5 um, the better the separation effect; On the contrary, the separation effect is worse.

Generally, crystalline solids and fibrous solids are easier to separate, while flocs and paste solids are more difficult to
separate. Due to the large maximum water solubility of flocs and paste solids, when spirally pushing sediment, it is easy to slip and affect the separation effect, so the flow rate should not be too large when separating flocs and paste solids.

The greater the weight difference between the solid phase and the liquid phase, the better the separation, and vice versa, the worse the separation effect The lower the liquid viscosity, the easier it is to separate. When the liquid viscosity is higher, the solids entrained in the clarified liquid increase, and the separation effect becomes worse. At this time, the material temperature can be increased and the viscosity can be reduced to improve the separation effect (the maximum feed temperature is not greater than 95 ºC).

Selection Of Feed Flow (I.E., Processing Capacity)

From a separation perspective, the smaller the feed flow rate, the smaller the axial flow rate of the material in the drum, the
longer the residence time of the material in the drum, and the better the separation effect. As the feed volume increases, the axial flow rate increases, and the retention time of the material in the drum decreases. The separation effect becomes worse.

The feed volume of the centrifuge is also limited by the maximum slag removal capacity of the spiral. If the feed volume is too large, the separated sediment will not be discharged in a timely manner, resulting in blockage of the drum.

Therefore, when using the centrifuge, the appropriate feed flow rate should be selected based on the material characteristics, separation requirements, and the solid content of the material, Generally, when the solid content is large, the feed rate should not be too large. The appropriate feed rate can be determined after comparing the separation effects of various flows. Generally, it is recommended that the flow rate should not be too large for materials that are difficult to separate, and the flow rate for materials that are easy to separate can be larger. However, attention should be paid to the maximum slag discharge amount of the spiral, otherwise it will cause material blockage

It is suitable for separating different feed under different process condition, and widely use in pharmaceutical, food, chemical, light industry, environmental protection industry etc…

 

How does it work ?

The feed product is pumped into the decanter centrifuges through the inlet. Feed goes into a horizontal bowl, which rotates. The bowl has is composed of a cylindrical part and a conical part. The separation takes place in the cylindrical part of the bowl. The fast rotation generates centrifugal forces up to 4000 x g. Under these forces, the solid particles with higher density are collected and compacted on the wall of the bowl. A scroll (also screw or screw conveyor) rotates inside the bowl at a slightly different speed. This speed difference is called the differential speed. This way the scroll is transporting the settled particles along the cylindrical part of the bowl and up to the end conical part of the bowl. At the smallest end of the conical part of the bowl, the dewatered solids leave the bowl via discharge opening. The clarified liquid leaves through a paring disc (internal centripetal pump).

 

With a 3 phase decanter centrifuge, it is possible to separate 3 phases from each other in one process step only. For example, two liquids which cannot be mixed because of different densities (e.g. oil and water) are separated from a solids phase. The heavy liquid (water) collects in the middle between the oil and the solids layer. Thus the two liquids separated from each other can be drawn off from the decanter. The solids are transported via the scroll to the discharge openings as it happens also in 2-phase separation.
Typical applications of 3-phase separation are the production of edible oils such as olive oil, oil sludge processing, the production of biodiesel etc.

Parameters and influencing factors of the separation

Feed, throughput and residence time
 

Through the feed, the separation medium to be processed can be input into the center of the infeed chamber of the scroll, where it is accelerated. The throughput will have an influence on the residence time.

Decanter Centrifuges Acceleration

The separation medium reaches its maximum speed in the decanter bowl, causing the solids to settle on the bowl inner diameter. A characteristic feature of the bowl is its cylindrical/conical shape.

Differential speed
 

There is a differential speed between the decanter bowl and the scroll, which is created by a gear unit on the industrial decanter centrifuges. The differential speed determines the solid content in the outfeed.

Filling volume / Weir discs or overflow weir
The clarified liquid flows to the cylindrical end of the bowl in the decanter centrifuge, from where it runs out through openings in the bowl cover. These openings contain precisely adjustable weir discs/weir plates by means of which the pond depth in the bowl can be set. The weir discs determine the filling volume of the bowl.

Advantages and limitations over competitive processes

Generally the decanter centrifuge has more advantages than disadvantages; however, there are some limitations when compared to other processes.

Decanter Centrifuges Limitations:
* The decanter centrifuges cannot separate biological solids with very small density differences, such as cells and viruses. A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge.
* The machine can be very noisy and can cause vibration.
* The device has a high-energy consumption due to high G-forces.
* The decanter centrifuge has high equipment capital costs. Hard surfacing and abrasion protection materials are required for the scroll to reduce wear and therefore reduce the maintenance of the scroll wear.
