Description

one

This invention relates to protecting the environment from the effects of oil and. oils. In particular, the device is designed to collect oil, oil and water-insoluble organic compounds from the surface of the water.

A skimming device is known, which contains a tray for receiving oil with an overflow wall and sidewalls attached to its ends, as well as a drum with curviline-shaped vanes turned with a concavity to the axis of rotation mounted on the tray between the sidewalls and mounted with a gap relative to the overflow wall l does not effectively separate oil from water when collecting it from a water surface.

The aim of the invention is to improve the quality of cleaning the water surface from oil.

This goal is achieved by the fact that the curvilinear blades are made spiral-shaped and are located at the perimeter of the drum with overlapping each other, the axis of rotation of the drum being placed at the waterline level, and the free edge of the overflow wall dbrsytsen in the direction opposite to the direction of the blades rotation.

FIG. 1 schematically shows the proposed device, a side view in FIG. 2 - the same, top view; in fig. 3 process of collecting and separating, 5 floating oil during the rotation of the drum.

Claims (2)

The device contains a tray 1 for receiving oil, the ends of which are attached to the sidewalls 2, and also mounted on the tray 1 between the sidewalls 2 rotatably a drum 3 with curvilinear spiral-shaped blades facing the axis of rotation 5 of the drum 3, which is located at the level waterline. In order to separate the oil 6 from the water 8 in the tray 1, a wall 7 was installed, the free edge of which turned in the direction opposite to the direction of rotation of the hoops that are located along the perimeter of the drum 3 overlapping each other. The drum is installed with a gap relative to the overflow wall 7. The device operates as follows. drum 3 begins to rotate around the axis of rotation 5 between the sides 2. Its blades 4, when rotated, capture the outer surface of the water with the floating oil 6 and lock it into the four-wall formed in this way, which is connected to the water area, the vessel from the fixed sidewalls 2, the tray and the movable blade . Each entry into the water due to; pi-9eleanly curved surface surface displaces water down under Tray t, thereby creating a continuous flow of oil from the water area to the drum / 31, and oil 6, having a lower density than water, moves to tray I, thickens in height by reducing the area in the vessel to overflow wall 7 and drains into tray 1, from where it is then removed the pipe 8 to a separate container. After taking in the tray 1 by the oil transfer, the portion of oil left from the oil returns to the vessel formed by the next blade 4, for which all the blades are mounted overlapping each other. The use of the proposed device makes it possible to improve the quality of cleaning the water surface from oil and other water-insoluble compounds that have a specific gravity less than the specific gravity of water. Claims of the Invention An oil recovery unit comprising a tray for receiving oil with an overflow wall and sidewalls attached to its ends, as well as a drum with curvilinear blades mounted rotatably on the tray between the sides, concave to the axis of rotation and mounted with a gap relative to the overflow walls, characterized in that, in order to improve the quality, to clean the surface of oil, curvilinear jionacirH is spirally shaped and pa -polr) kenes around the perimeter of the drum with Giere rytyem d0uga each axis in); As a drum, it is placed at the spinning institute, and on the edge of the overflow wall, the side is opposite to the direction of the rotation of the blades. .
