Product Description

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 thesedimentation rate of solid particles under the action of centrifugal force to achieve solid liquid separation. The centrifugeconsists 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.

Advantages

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.

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.
