Advantage Analysis Of Screw Sludge Dewatering Machine
Oct 18, 2018

In the sewage treatment project, the common treatment process with good effect, low investment and wide application is activated sludge method. There must be a sludge dewatering machine in the downstream process of the system. The performance of the sludge dewatering machine directly affects the sewage treatment effect. The sludge dewatering machine currently used in this field in China is a conventional traditional structural form (plate and frame pressure). Filter, belt filter, centrifugal filter, etc.). They all have certain defects and deficiencies, which affect the final effect of sewage treatment. In order to improve the treatment effect of sewage sludge, it is necessary to develop, develop, produce and apply new-type, high-efficiency, no secondary pollution sludge dewatering machine. 


Lifeng environmentally-friendly stacked screw sludge dewatering machine is a new generation of new filtering equipment without liquid filter device and high-speed centrifugal force. The filter body is composed of filter body and screw thrust shaft. The filter body is It consists of a concentrating part and a dewatering part. When it is operated by one or more sets of screw thrust shafts, the multiple living laminated sheets disposed on the periphery of the spiral pushing shaft are relatively moved to make the filtrates in the relative swimming laminations. Quickly filter out in the gap to achieve no blockage and no need to clean. At the same time, the volume in the spiral chamber is continuously contracted, the internal pressure is increased, and the pressure regulating mechanism of the back pressure plate is continuously increased, and the solid content of the filter cake is continuously increased. Under the continuous driving of the screw thrust shaft, the filtrate is continuously separated and discharged, and the sludge continuously Exhausted and dehydrated, Zui replaced the filter cloth and centrifugal filtration with a unique and delicate filter mode.


With unique and innovative design, Lifeng Environmental Protection solves the wear between the screw shaft and the moving lamination, which greatly prolongs the service life of the screw shaft and lamination, especially for the unit size of WJDL-301 and above. The problem of repairing the repair and the cost of repairing can be avoided.


Lifeng environmentally-friendly stacked screw sludge dewatering machine breaks through the traditional filter design concept, absorbs the new solid-liquid separation technology of Zui International in the 21st century, and creatively designs a new generation with neither filter nor high-speed centrifugal force. Sewage solid-liquid separation filter, which can be widely used in food, medicine, petrochemical, chemical, catering, poultry storage, urban sewage and other industries, is an ideal sludge dewatering equipment.


Lifeng environmental dehydration advantage


1. Lifeng environmental protection stack screw sludge dewatering machine is mainly used for sludge treatment not concentrated, and has the dual functions of dehydration, saving construction investment, such as concentrated sludge dewatering, not simply dehydration treatment has significantly improved and better dehydration.


2. The Lifeng environmental protection stack screw sludge dewatering machine uses the different sections of the concentrated section filter belt and the press section of the filter belt, and uses the line speed to optimize the solid-liquid separation time.


3, Lifeng environmental protection stack screw sludge dewatering machine can be washed with filtrate filter belt, saving operating costs.


4. Lifeng environmental protection stack screw sludge dewatering machine can run continuously and shift.


5. The filter has an automatic correction filter, pneumatic tension and automatic tension adjustment.


6. Simple operation, stable operation and convenient maintenance.
