Product Description

This equipment is a LW series product, commonly used for dehydration and concentration. Widely used for maximum dewatering requirements of municipal and industrial wastewater sludge. It is characterized by small size, high rotational speed, and small processing capacity, and is used in situations where large separation factors and small processing capacity are required. According to practical use, it can be divided into: clarification type, dehydration type, concentration type, separation type, classification type, extraction type; Users can choose by themselves. Dehydration horizontal spiral centrifuge is suitable for easily separated materials with large particle size, large solid-liquid density difference, low viscosity, high concentration, strong processing capacity, and higher dryness than clarity. Materials such as sludge or wastewater containing fine particles usually require the addition of flocculants to condense the fine particles into large particles, which are then dewatered using a sedimentation centrifuge.

 

The horizontal screw centrifuge relies on the density difference between the solid and liquid phases to accelerate the sedimentation rate of solid particles under the action of centrifugal force to achieve solid liquid separation. The centrifuge consists of two rotors, one called a drum, and the other rotor is a screw discharger (referred to as a screw). When the drum rotates at a high speed, the slurry inside the drum rotates with the drum and is subjected to a centrifugal force that is many times greater than gravity. In this way, solid particles will be separated from the liquid and settle onto the inner wall of the drum from the centrifuge drum shaft. The screw discharger located inside the drum rotates at a speed lower than the drum and pushes the deposited solid particles to the slag outlet, The differential rotational speed between the outer drum and the screw discharger depends on the transmission ratio of the differential and its rotational speed.

 

 

This liquid clarifying device adopts horizontal design which balances the layout of electric motor and bowl. As a result, outstanding operation stability generates minimized vibration.

 

Dual electric motor control enables stepless speed adjustment on bowl and spiral components.

 

Scroll conveyor flight inside this continuous centrifuge is painted by abrasion resistant alloy or welded by hard alloy. Moreover, main components on our horizontal decanter centrifuge, such as rotating bowl and spiral parts, are made from corrosion resistant stainless steel or dual-phase steel, whereby offering exceptional speed limits and separation ratio.

 

Our mud dewatering equipment comes with three options including cycloidal gear, planetary gear and hydraulic differential, resulting in large rang of differential adjustment. Therefore, this industrial centrifuge can be applible to diverse solids.

 

Multiple protections are available on our horizontal decanter centrifuge to ensure operation safety, including over-vibratation protection, bearing temperature detection, screw conveyor torque protection rotating and differential speed detection, as well as nitrogen-filled explosion-proof protection, motr overload and over heat protection.

 

JG type rubber shock absorber requires no anchor bolts.

Working principle of mineral classification and dehydration

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.

 

According to user's requirement, the product contact parts can be made of austenite stainless (321, 316L….), Haynes alloy, titanic alloy or other anti-erosion materials.

1. Feeding pipe 2. Discharge screw 3. Drum 4. Casing 5. Differential mechanism

 

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.

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
