Uses the place: Mainly uses in the petroleum chemical industry sewage treatment place in the flotation cell, the oil separation tank the dirty oil (dregs) recycling. Selects the condition pond: Enclosed or open type square shape pool. Pond specification: May according to the user request design manufacture. Operation medium: The petroleum chemical industry, the oil field, the city, the leather, choose the paper and so on each kind of sewage. Operating temperature: ≤70℃. Service pressure: Atmospheric pressure. Principle of work: The ZLG-2 link joint type blows the dregs machine ,the ZLG-3 link joint type to blows the kerosene engine is by the electric motor is a power, through the cycloid pin gear speed reducer, the drive sprocket, the driving chain drives the driveshaft, from the moving axis revolution, two to install on the clamping plank chain wheel’s clamping plank chain link leads blows the dregs (oil) the board slowly to make theellipse circumference revolution, when blows the rotary-inversion to the hydraulic pressure on, the liquid level in oil (dregs), pushes immediately to the collecting pipe platoon walks, thus recycles waste and the sewage goal of rough purification.
