1. Chain type oil/dregs scraper is suitable for oil skimming and sediment scraping of rectangle pool such as sedimentation basin and separation tank in oil refinery factory, water production factory and wastewater treatment factory.

2. This machine should be used together with oil gathering pipe and sludge discharging valve to separate oil residue and sand for primary purification.

3. Wastewater should flow into tank through grill so as to prevent large vol. particles.


Driven by two parallel chains, scraper moves linearly with a low speed that improves sedimentation and scraping capacity while causes no big disturbance to waste water.

  u Circulating movement of two parallel closed chains ensures natural steering which simplifies control system and reduces cost. Driven device is installed on the platform of tank for convenient maintenance of machine.
