QXDL-304 Spiral Screw Sludge Dewatering Machine
Product Introduction

The Waste Water Treatment Eco-friendly Spiral Screw Sludge Dewatering Machine QXDL-304 is a high-capacity automatic dewatering unit engineered for continuous operation in large-scale municipal and industrial wastewater facilities. This system features an extended screw shaft with progressive pitch reduction from 160mm to 50mm, generating mechanical compression up to 0.9 MPa. The advanced ring stack design incorporates 40 percent more filtration surface area compared to standard models, enabling processing of 120-240 kg/h dry solids with feed concentrations ranging from 0.5 to 6 percent. The integrated torque-based control system with VFD drive automatically adjusts screw speed and back-pressure, maintaining consistent cake dryness of 22-32 percent DS across varying feed conditions. Self-cleaning differential motion between moving and fixed rings eliminates filter cloth blinding and reduces maintenance requirements.

Core Advantages
◈
High Capacity Throughput
Processes 120-240 kg/h dry solids with feed sludge concentrations up to 6 percent, suitable for large municipal and industrial plants.
◈
Energy Efficient Operation
Total power consumption of 3.75 kW with low-speed operation (1.5-5 RPM) results in energy savings of 70 percent compared to centrifuge systems.
◈
Zero Clogging Design
Self-cleaning ring stack eliminates filter cloth blinding, reducing maintenance frequency and eliminating high-pressure backwash requirements.
◈
Automated Process Control
VFD-driven torque control with Modbus RTU communication enables remote monitoring and automatic adjustment to feed variations.

Frequently Asked Questions
Q What feed sludge concentration is required for optimal operation? +
The QXDL-304 operates effectively with feed sludge concentrations ranging from 0.5 to 6 percent solids. For optimal performance and to achieve 22-32 percent DS cake, a feed concentration of 2-4 percent is recommended. Lower concentrations may require reduced throughput or increased polymer dosing to maintain cake dryness.
Q How does the self-cleaning ring stack prevent clogging? +
The moving rings are driven by friction from the rotating spiral shaft, creating a continuous differential motion against the fixed rings. This shearing action dislodges trapped solids and prevents material accumulation. The self-cleaning mechanism eliminates the need for high-pressure backwash systems and reduces water consumption by up to 90 percent compared to conventional designs.
Q What maintenance intervals are required for the ring stack? +
Ring stack inspection should be performed every 2,000 operating hours. Individual ring segments with clearance exceeding 0.4mm should be replaced. Under normal operating conditions with non-abrasive sludge, the ring stack provides 15,000-18,000 hours of service life. Complete ring set replacement is recommended when more than 30 percent of rings exceed wear limits.
Q Can this machine be integrated with existing control systems? +
Yes. The QXDL-304 features Modbus RTU communication protocol, enabling seamless integration with SCADA systems and existing plant control networks. The unit provides real-time torque, speed, and runtime data, with alarm outputs for fault detection and remote diagnostics.
Operational Notes & Safety Precautions
⚠ Disconnect power supply before opening inspection ports or performing maintenance.
⚠ Do not exceed maximum back-pressure of 0.9 MPa to prevent ring stack damage.
⚠ Lubricate drive chain every 500 operating hours with food-grade grease.
⚠ Verify torque limiter calibration annually; slip torque set to 110 percent of motor rating.
⚠ Install upstream screening (2mm mesh) to prevent foreign object ingress.
⚠ Ensure proper electrical grounding with resistance below 10 ohms.
