Oil slick recovery device

Abstract

The invention provides an oil slick recovery device, which comprises three buoys (5) and an oil slick suction device (4), wherein the three buoys (5) are fixedly connected to form a triangle by a connecting frame; the oil slick suction device (4) is connected with the three buoys (5), and has a sleeve shape; a taper reamed hole is formed at the oil slick inlet end (41) of the oil slick suction device (4); and the periphery of the taper reamed hole is outwards bent to form an r-shaped weir crest (43). When flowing to the periphery of the weir crest of the oil slick suction device, oil slick or scum can flow into the weir crest without hindrance along the edge of an r shape, and is difficult to accumulate about the weir crest; and the oil slick inlet end of the oil slick suction device adopts the taper reamed hole structure, so the external diameter of the oil slick inlet end and the oil slick is easier to rapidly and forcibly recover.

Description

Oil recovery device technical field The invention relates to a floating oil recovery device. Background technique At present, in the production process of petroleum, petrochemical, steel, food and other fields, a large amount of oily sewage is discharged into various steel storage tanks, dirty oil pools, and sedimentation tanks every day, and the surface contains a large amount of oil slick. The recovery of floating oil mostly adopts oil collection devices such as rope type and cofferdam type. When the water level in the tank or in the oil pool rises to a certain liquid level, the oil slick pump is turned on to suck the floating oil on the surface. Due to the thickness of the slick oil and the height of the liquid level, it is very difficult for the oil collection work. The oil collection work or If it is not carried out in time or the oil collection time is too long, a large amount of water will be collected, which will cause unnecessary troubles for the subsequent work,...
