Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1 to 4, a novel oil decanter comprises two groups of buoys 1, an oil decanting main pipe 2 located between the two groups of buoys 1, and a counterweight pipe 3 connected to the buoys 1 and used for adjusting the buoyancy of the buoys 1. The oil decanter can be integrally made of PE, PP, PVC and other plastic materials with stable performance, and can contact strong acid and strong alkali because the working medium contains oil. In addition, the oil inlet of the oil decanter is a strip-shaped seam with the length of 20mm to 30mm, the oil inlet can be connected in series according to the area of the water pool, and the oil inlet working condition is greatly improved.

The floating barrel 1 has buoyancy and can float on the oil surface, and the main oil decanting pipe 2 is provided with a strip-shaped long seam with the width of about 20mm-30mm, and the strip-shaped long seam is an oil inlet weir port 5. The balance weight layer 6 is placed in the balance weight pipe 3, the balance weight layer 6 can be made of weighting materials such as pea stones and iron sands, and the amount of the pea stones or the iron sands in the balance weight pipe 3 is increased or decreased, so that on one hand, the depth of the oil inlet weir mouth 5 immersed in liquid is adjusted, and on the other hand, the height balance of two ends of the oil decanter can be adjusted. Meanwhile, because the pea stones or iron sands filled in the balance weight pipe 3 are positioned at the lowest position of the oil decanter, the gravity center of the oil decanter is lowered, like ballast stones of ships, so that the oil decanter keeps stable during operation. When the oil decanting device is used, the oil inlet weir crest 5 of the oil decanting main pipe 2 is located between the oil surface and the water surface through the adjustment of the counterweight layer 6, oil enters from the oil inlet weir crest 5 at the later time, the water cannot enter, and the oil entering the oil decanting main pipe 2 is discharged from the oil discharging hose 4.
