Disc Centrifuge Self-Cleaning Separator 20m³/h for Waste Engine Oil Purification

Product Overview

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.

Applications

Waste Engine Oil Recycling: Re-refining used motor oil, gear oil, hydraulic oil into base oil feedstock
Industrial Lube Oil Reclamation: Turbine oil, compressor oil, transformer oil purification
Marine Engine Waste Oil: Sludge and bilge oil pre-treatment for MARPOL compliance
Metalworking Fluid Recovery: Removing tramp oil and solids from cutting fluids

Working Principle

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.

FAQ

Q: What types of waste oil can the DHKY process?

It is mainly applied for fuel purification and lubricant regeneration treatment for marine and onshore power station equipment. It effectively reduces diesel engine wear and extends the service life of mechanical equipment.

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).
