Product Description

Product Description

sludge dewatering machine

Stacked screw sludge dewatering machine is a new type of equipment integrating thickening and dewatering, the core of which consists of fixed ring, travelling ring and screw shaft, and sludge dewatering is realised through the filtering gap formed by the static and dynamic rings staggered and the propulsion and extrusion of the screw shaft. The equipment can directly process low concentration sludge with water content of 90%-99.5%, and the sludge is extruded in the gradual gap by the rotating spiral shaft, and the final output is sludge cake with water content of 75%-80%, and the power consumption per tonne of processing is only 1-2kW/h. 
Its unique advantage lies in the design of 'self-cleaning without filtering cloth': the travelling ring produces axial movement when it rotates with the spiral shaft, and automatically dewatering the sludge with the filtering cloth. Its unique advantage is 'no filter cloth self-cleaning' design: the swimming ring generates axial movement when rotating with the screw shaft, automatically removing the sludge fibre in the gap, completely solving the problem of filter cloth clogging in the traditional equipment, and reducing the maintenance cost by 60%. The equipment covers an area of only 1-3 square metres, equivalent to 1/5 of the traditional plate and frame machine, and can be flexibly installed in small sewage stations; the fully automatic PLC control supports 24-hour unattended operation, together with the function of frequency conversion speed regulation.

Sludge dewatering machine products all-round display

Structural design of sludge dewatering machine: the main body consists of fixed ring, swimming ring stacked on top of each other, and screw shaft running through it. The front section is the thickening section and the back section is the dewatering section, with compact structure and small footprint.
Performance advantages of sludge dewatering machine: strong adaptability to sludge, can handle low concentration sludge without thickening first. The equipment is not easy to be clogged, can run continuously and automatically, and has low energy consumption, easy operation and low maintenance cost.

Application scope of stacked-screw sludge dewatering machine

Sludge dewatering machine can self-adapt to municipal sewage, food processing, printing and dyeing and other industries with high organic matter, high oil content sludge treatment, especially suitable for village and township decentralised wastewater treatment scenarios, providing an economical and convenient solution for sludge reduction and resourcing.

Before and after sewage treatment

Sludge dewatering machine Before processing
The water quality is turbid: The sewage is blackish gray, with suspended solids (such as grease and food residues) visible to the naked eye, and it emits a pungent odor.
High pollution indicators: COD (Chemical Oxygen Demand) exceeds 500mg/L, BOD (Biochemical Oxygen Demand) exceeds 200mg/L, and ammonia nitrogen content > 30mg/L;
Ecological hazard: Direct discharge will lead to eutrophication of water bodies, breed algae and damage aquatic ecosystems.
Sludge dewatering machine After processing
The water quality is clear: The effluent is transparent and colorless, with a suspended solids removal rate of over 95%, and no visible impurities or odors.
Indicators met: COD < 50mg/L, BOD < 10mg/L, ammonia nitrogen < 5mg/L, in compliance with the national first-class A discharge standard;
