Low Energy Dual Section Sludge Dewatering Machine Automatic Operation Easy Maintenance

Low Energy Consumption Sludge Dewatering Machine Automatic Operation Easy Maintenance

Brief Description

The machine consumes little energy, resulting in economical long-term operating costs, aligning with green factory principles. It supports fully automated continuous operation, requiring no manual supervision. Daily maintenance is simple, eliminating the need for complex filter cloth replacements, significantly reducing the operational burden, making it particularly suitable for small and medium-sized industrial enterprises with limited staff.

Product Overview

The screw press sludge dewatering machine boasts multiple core advantages: uninterrupted clog-free operation, long-lasting wear resistance, extremely low mechanical loss, economical energy consumption and user-friendly operation. It thoroughly resolves the technical bottlenecks plaguing earlier sludge dewatering machines, namely frequent clogging, excessive space occupation, incapability to handle low-concentration sludge and oily sludge, high energy consumption and cumbersome operation, thus achieving high-efficiency and energy-saving dewatering effects. This all-in-one unit integrates a fully automatic control cabinet, flocculation mixing tank, specialized sludge thickening-dewatering body and filtrate storage tank. Operating in full automation, it efficiently completes flocculation, carries out continuous sludge thickening and press dewatering, and ensures collected filtrate is recycled or properly discharged.

Working Principle

Featuring a dual-section design of thickening and dewatering, the screw press sludge dewatering machine relies on physical pressure for sludge treatment. After gravity thickening in the front thickening section, sludge is pushed into the rear dewatering section. When moving forward, the continuous narrowing of filter gaps and screw pitch, combined with the obstruction of the back pressure plate, forms intense internal pressure, which steadily reduces the sludge volume and achieves thorough dehydration.

Key Design & Performance Features

1. Low-Concentration Direct Dewatering, Low Infrastructure Costs

The screw press sludge dewatering machine integrates both thickening and dewatering sections, enabling it to handle both high-concentration and low-concentration sludge directly, from thickening to dewatering the concentrated water. It is suitable for a wide range of sludge concentrations, from 2000mg/L to 50000mg/L.

2. Fixed and Moving Rings Replace Filter Cloth, Self-Cleaning, Clog-Free, and Easy to Handle Oily Sludge

Under the rotation of the screw, the moving rings in the screw press sludge dewatering machine continuously shift relative to the fixed rings, achieving a continuous self-cleaning process and avoiding the clogging problems commonly found in traditional dewatering machines. Therefore, it has a strong capacity for handling oily sludge, is easy to separate, and does not clog; moreover, it requires no external water for high-pressure washing, is clean and environmentally friendly, odorless, and produces no secondary sludge.

3. Low-speed operation, low noise, and low energy consumption

The screw press sludge dewatering machine relies on internal pressure for dewatering, eliminating the need for large machines like rollers. Its low operating speed of only 2-3 revolutions per minute results in water and energy savings, as well as low noise. Its average energy consumption is 1/8 that of a belt press and 1/20 that of a centrifuge, with a unit power consumption of only 0.01-0.1 kWh/kg-ds, reducing the operating costs of wastewater treatment systems.

4. Fully automatic control and simple operation and management

Applications

Municipal sewage, domestic wastewater, covering food, beverage, chemical, leather, welding material, papermaking, printing-dyeing, pharmaceutical, electroplating, oil & electric power, coal mining, brewing, livestock farming, kitchen sewage, water treatment plants, power generation plants, and steel manufacturing facilities.
