Product DescriptionIntroduction to Sludge Dewatering Machinessludge screw type press is composed of screw body, driving device, filtrate receiver, mixing system and frame. When the volute press dewatering operation, sludge will be transported to the mixing tank by sludge feed pump, at the same time, the solid polymer has been added to the mixing tank quantitatively by the polymer feed pump. Mixing motor drives the whole mixing system to make the sludge and polymer fully mixed and then flocs will be produced. When the liquid level arrives at the superior level of the liquid level sensor, the liquid level sensor gets the signal to make the motor of screw body operates, then begins to press the sludge which has flows into the screw body. Sludge will be transported to the outlet step by step by the effect of screw shaft; filtrate will flow out by the space of fixed rings and moveable rings.Screw-type Sludge Treatment EquipmentScrew Press Product IntroductionI. Product OverviewThe screw press is a highly efficient, energy-saving sludge dewatering equipment widely used in municipal sewage treatment, industrial wastewater treatment, food processing, chemical, pharmaceutical, and textile dyeing industries. It employs the principle of screw compression, achieving continuous sludge dewatering through the overlapping and rotation of moving and stationary rings. It features a compact structure, simple operation, and stable performance.II. Working PrincipleThe screw press primarily consists of a drive unit, screw press body, filtrate tank, and flocculation mixing tank. Its operation follows these steps:Flocculation Mixing: Sludge reacts thoroughly with flocculant in the mixing tank to form larger flocs.Gravity Dewatering: Flocculated sludge enters the screw press body for preliminary dewatering under gravity.Pressure Dewatering: The screw shaft propels the sludge forward, progressively narrowing the gap between moving and stationary rings. The sludge undergoes further dewatering through compression.Sludge Cake Discharge: The dewatered sludge cake is discharged through the outlet, while the filtrate is discharged via the filtrate tank.III. Product FeaturesHigh Efficiency & Energy Savings: Continuous operation with high throughput, low energy consumption, and reduced operating costs.High Automation: Fully automatic operation reduces manual intervention and labor intensity.Compact Footprint: Compact structure and easy installation suit space-constrained environments.Low Maintenance: Self-cleaning rotating and stationary rings minimize clogging and maintenance costs.Versatile Adaptability: Suitable for diverse sludge types, including organic, inorganic, and mixed sludge.Environmentally Friendly: Sealed operation prevents secondary pollution and meets environmental standards.
