The utility model relates to the technical field of sewage surface oil slick and scum removal, in particular to a high-efficiency oil remover.
Background
In industrial production, oil stains often leak into cooling water, or floating oil is on the surface of machine tool cutting fluid and needs to be recovered and cleaned. The oil stain on the water surface is cleaned and absorbed mainly by a single fixed caliber oil suction port installed on a floating island. The oil-water separation treatment was performed by pumping.
When the fixed caliber oil suction port absorbs floating oil in the flowing water tank, a large amount of air is easy to suck, and the oil suction efficiency is affected by factors such as floating island fluctuation caused by flowing water surface wave surge, and the oil suction is not continuous. The suction port is close to the liquid surface and sucks more air to cause cavitation damage to the pump body.
The common pump has limited suction lift, is not suitable for being used under the condition that the height of an oil pool is higher from the ground, and the oil stain surface contains impurities and solid floating oil with higher viscosity and can block the pipeline of the common oil suction device.
The steel belt type oil absorbing machine is generally immersed into the liquid surface to be stained with oil dirt through the steel belt, the oil removing method is extremely low in efficiency and is not suitable for the condition of large amount of oil dirt generation, such as oil removal of a steel-making rotational flow pool, manual scooping is adopted at present, the work load is extremely high, the labor intensity is high, and potential safety hazards are many.
Therefore, an efficient oil remover is needed, which is not influenced by the use height, has high oil absorption efficiency, and has short pipeline of the whole system and little influence of oil stains.
