Automatic Spiral Screw Sludge Dewatering
High Energy-saving Industrial Wastewater Automatic Spiral Screw Sludge Dewatering Machine
100-200 kg/h Dry Sludge 2.95 kW Power 1830 kg Weight 3820 mm Length 1490 mm Width
Product Introduction

The High Energy-saving Industrial Wastewater Automatic Spiral Screw Sludge Dewatering Machine QXDL-352 is engineered for heavy-duty dewatering in industrial wastewater treatment. This unit features a robust screw shaft with progressive pitch reduction from 155mm to 52mm, generating compression up to 0.85 MPa. The ring stack incorporates a double-layer filtration design, increasing effective surface area by 35 percent. Processing 100-200 kg/h dry solids with feed concentrations of 0.5-6 percent, this machine achieves cake dryness of 22-30 percent DS. The automatic control system with VFD drive adjusts screw speed and back-pressure in real time, ensuring stable operation under varying industrial load conditions. Self-cleaning ring mechanism eliminates clogging from industrial debris.

Frequently Asked Questions
Q What industrial wastewater types are compatible with the QXDL-352? +
The QXDL-352 is compatible with a wide range of industrial wastewater streams, including chemical manufacturing, petrochemical, pharmaceutical, food processing, pulp and paper, textile, and municipal effluents. The SS304/SS316L construction provides resistance against corrosive chemicals, while the self-cleaning ring stack effectively handles fibrous and sticky materials common in industrial wastewater.
Q How does the automatic load adaptation system work? +
The system uses a torque sensor to monitor the load on the screw shaft. As feed conditions change, the VFD automatically adjusts screw speed and back-pressure cone position to maintain optimal dewatering performance. This eliminates the need for manual adjustments and ensures consistent cake quality even during batch processing cycles.
Q What maintenance schedule is recommended for industrial applications? +
For industrial wastewater applications, ring stack inspection is recommended every 1,800 operating hours. Replace individual ring segments with clearance exceeding 0.4mm. Under typical conditions, the ring stack provides 14,000-17,000 hours of service. Complete ring set replacement is recommended when more than 30 percent of rings exceed wear limits. Lubricate drive chain every 450 hours.
Q Can the QXDL-352 handle variable flow rates common in industrial settings? +
Yes. The VFD-driven system with torque-based control automatically adjusts to varying flow rates and solids concentrations. The machine can process feed sludge with concentrations from 0.5 to 6 percent while maintaining consistent cake dryness. The control system also features alarm outputs for abnormal conditions, ensuring reliable operation in variable industrial environments.
Operational Notes & Safety Precautions
■ Disconnect power before opening inspection ports or performing maintenance.
■ Do not exceed maximum back-pressure of 0.85 MPa to prevent ring stack damage.
■ Lubricate drive chain every 450 operating hours with high-temperature industrial 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 in industrial wastewater.
■ Ensure proper electrical grounding with resistance below 10 ohms.
