Screw Press Livestock Sludge Dewatering Machine QXDL-402

Screw Press Livestock Sludge Dewatering Machine is designed for livestock sludge dewatering. It adopts advanced screw pressing technology to efficiently separate water and solids in sludge, and achieve sludge reduction and harmless treatment. The equipment has a compact structure, easy operation, low maintenance cost, and can significantly improve sludge treatment efficiency and reduce treatment costs. The unique dewatering process ensures that the moisture content of the sludge after dehydration is low, which is convenient for subsequent transportation and disposal, and effectively reduces environmental pollution. It is suitable for all kinds of livestock farms and is an environmentally friendly and efficient sludge treatment.

Product Introduction

The Screw Press Livestock Sludge Dewatering Machine QXDL-402 is a heavy-duty dewatering system designed for high-capacity agricultural wastewater treatment. This unit is specifically engineered to handle the large volumes of manure and digestate generated by intensive livestock operations including pig, cattle, and poultry farms. The machine features an extended heavy-duty screw shaft with progressive pitch reduction from 160mm to 50mm, generating mechanical compression up to 0.85 MPa. The large-diameter ring stack incorporates a quadruple-layer filtration design with 50 percent more surface area compared to standard models, enabling processing of 160-320 kg/h dry solids with feed concentrations ranging from 1 to 8 percent. The machine achieves cake dryness of 22-30 percent DS. The integrated high-torque drive system with VFD and automatic torque control ensures stable operation under heavy load conditions. The all-stainless-steel construction provides durability in corrosive manure environments, while the self-cleaning ring mechanism eliminates clogging from fibrous agricultural waste and straw residues.

Frequently Asked Questions
Q How does the quadruple-layer ring design improve dewatering performance in agricultural applications? +
The quadruple-layer ring design incorporates four independent filtration layers with progressively smaller gap spacing. This configuration increases the effective filtration surface area by 50 percent compared to standard designs, allowing for higher throughput of fibrous manure and straw residues. The layered design provides redundancy, ensuring continued operation even if one layer experiences partial clogging from agricultural debris. The independent layers also allow for more efficient drainage of free water and bound water from the manure matrix.
Q What feed solids concentration is recommended for livestock wastewater? +
The QXDL-402 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. Higher concentrations above 8 percent may cause bridging at the inlet, while lower concentrations may require reduced throughput or polymer addition to maintain cake dryness. The VFD-driven system automatically adjusts to handle variations in manure consistency common in livestock operations.
Q What maintenance schedule is recommended for high-capacity agricultural dewatering? +
For high-capacity livestock 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 0.45mm should be replaced. Under typical conditions, the ring stack provides 12,000-15,000 hours of service life. Complete ring set replacement is recommended when more than 30 percent of rings exceed wear limits. Lubricate drive chain every 400 hours with heavy-duty agricultural grease. Clean the feed hopper daily to prevent manure accumulation and inspect the spray nozzles weekly.
Q Can this machine be integrated with biogas plant digestate processing? +
Yes. The QXDL-402 is specifically designed for biogas plant digestate processing, handling the high-fiber and high-moisture content typical of anaerobic digestion residues. The automatic control system with torque-based load adaptation handles variable digestate consistency, while the SS304/SS316L construction provides resistance against acidic conditions in digestate. Modbus RTU communication enables integration with biogas plant SCADA systems for automated monitoring and control, making it ideal for agricultural waste-to-energy facilities.
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 deformation.
Lubricate drive chain every 400 hours with agricultural-grade heavy-duty grease.
Verify torque limiter calibration annually; slip torque set to 110 percent of motor rating.
Install upstream screening (2mm mesh) to prevent sand, gravel, and large debris ingress.
Ensure proper electrical grounding with resistance below 10 ohms.
