| High Light | Self-Cleaning Sludge Discharge ，Waste Oil Dehydration Demulsification ，Continuous Three-Phase Separation | ||
The DHKY470 is a self-cleaning disc stack centrifuge engineered for waste engine oil purification. It removes water, sludge, carbon fines, and metal particles from used lubricating oil through high-G three-phase centrifugal separation. With automatic slag ejection and PLC touch-screen control, it enables continuous 24/7 operation with minimal operator intervention.

The DHKY470 uses high-speed centrifugal force generated by a rotating bowl stack of conical discs. Feed oil enters the bowl through a central pipe and is distributed between disc gaps. Under 10,000G+ centrifugal force, the three phases separate by density: clean oil exits the centripetal pump at the top light-phase outlet, water is discharged through the heavy-phase port, and solids accumulate on the bowl wall. The self-cleaning mechanism periodically opens the bowl discharge ports via hydraulic pressure, ejecting accumulated sludge without stopping the machine.

| DHKY611 | 3-10 m³/h | 18.5 kW | High-throughput refinery operation |
Q: What types of waste oil can the DHKY process?
Q: Does it require pre-treatment?
A: We recommend a coarse screen filter (60–100 mesh) upstream to remove large debris. For heavily emulsified oil, pre-heating to 60–80 °C improves separation efficiency.
Q: How often does the self-cleaning cycle trigger?
A: The PLC allows programmable partial ejection intervals (5–60 min adjustable) based on sludge content. Total ejection can be set for end-of-batch or high-sludge scenarios.
Q: What is the typical water and solid removal rate?
A: Final oil achieves ≤0.1% water and ≤0.05% solid content after single-pass operation.
Q: Is installation and training included?
A: We provide commissioning manuals, remote video guidance, and optional on-site installation by our engineers (quoted separately based on location).
