Automatic Livestock Wastewater Treatment Screw Press Sludge Dewatering Machine QXDL-401

Automatic Livestock Wastewater Treatment Screw Press Sludge Dewatering Machine has a unique screw pressing mechanism that can effectively separate the solid sludge from the liquid in the livestock wastewater. The high-precision pressing process ensures excellent dewatering performance and significantly reduces the water content of the sludge. It simplifies the treatment of waste and also helps protect the environment by minimizing the pollution potential of wastewater. With automated operation, it requires less labor and can work continuously, thereby increasing productivity.

QXDL-401
Product Introduction

The Automatic Livestock Wastewater Treatment Screw Press Sludge Dewatering Machine QXDL-401 is specifically engineered for the challenging wastewater conditions found in livestock operations including pig, cattle, and poultry farms. This unit features a heavy-duty screw shaft with progressive pitch reduction from 150mm to 48mm, generating compression up to 0.8 MPa. The ring stack is designed with wider gap tolerance to handle manure fibers, straw residues, and high-solids content common in agricultural wastewater. Processing 80-160 kg/h dry solids with feed concentrations of 1-8 percent, this machine achieves cake dryness of 22-30 percent DS. The automatic control system with VFD drive adjusts to varying manure feed conditions, while the self-cleaning ring mechanism prevents clogging from fibrous agricultural waste. The all-stainless-steel construction provides corrosion resistance against acidic manure and ammonia-rich environments.

Frequently Asked Questions
Q How does the QXDL-401 handle fibrous manure and straw residues? +
The QXDL-401 features a specially designed ring stack with wider gap tolerance of 0.3-0.5mm, allowing fibrous materials and straw residues to pass through without clogging. The self-cleaning differential motion between moving and fixed rings continuously dislodges trapped particles. The VFD drive allows speed adjustment to handle varying manure characteristics, ensuring consistent dewatering performance even with high fiber content.
Q What feed solids concentration is recommended for livestock wastewater? +
The QXDL-401 operates effectively with feed solids concentrations ranging from 1 to 8 percent. For optimal dewatering performance and achieving 22-30 percent DS cake, a feed concentration of 2-5 percent is recommended. Lower concentrations may require reduced throughput or polymer addition, while higher concentrations above 8 percent may cause bridging at the inlet and should be diluted or fed at reduced rates.
Q What maintenance schedule is recommended for agricultural wastewater applications? +
For livestock wastewater applications, ring stack inspection is recommended every 1,500 operating hours due to the abrasive nature of manure and sand particles. Individual ring segments with clearance exceeding 0.4mm should be replaced. Under typical conditions, the ring stack provides 12,000-15,000 hours of service life. Lubricate drive chain every 400 hours with heavy-duty agricultural grease. Clean the feed hopper weekly to prevent manure accumulation.
Q Can this machine be integrated with biogas plant operations? +
Yes. The QXDL-401 is fully compatible with biogas plant operations, processing digestate from anaerobic digestion systems. The automatic control system with torque-based load adaptation handles variable digestate consistency. Modbus RTU communication enables integration with biogas plant SCADA systems for automated monitoring and control. The SS304/SS316L construction provides resistance against acidic conditions in digestate.
Operational Notes & Safety Precautions
■ Disconnect power before opening inspection ports or performing maintenance.
■ Do not exceed maximum back-pressure of 0.8 MPa to prevent ring stack damage.
■ Lubricate drive chain every 400 hours with agricultural-grade grease.
■ Verify torque limiter calibration annually; slip torque set to 110 percent of motor rating.
■ Install upstream screening (2mm mesh) to prevent sand and gravel ingress.
■ Ensure proper electrical grounding with resistance below 10 ohms.
