Abstract

The invention relates to environmental protection. The purpose of the invention is the improvement of water purification efficiency. The device consists of a drum 1, an oil collecting funnel 2, an axial chamber 3, flexible hoses 4, and oil pumping nozzles 5. The axial chamber 3 includes an axial tube with lower transfusion holes, precise holes, and a tube. The pipe of larger diameter, the groove of the axle pipe has flow-through holes along its perimeter. The funnel 2 has hinges and is oriented vertically relative to the oil film 19. Due to the hinge suspension of the oil hopper, a layer of oil pops up into the upper part of the funnel and is sucked through the axial chamber from the bottom up to the pipe for pumping oil without emulsifying the latter. 1 hp f-ly, 4 ill. with S (L

The invention relates to the cleaning of the surface of water bodies from film oil.

The purpose of the invention is to increase the efficiency of cleaning the water surface,

FIG. 1 shows the device, a general view; in FIG. 2 a drum, cross section; Fig, 3 - axial chamber, cross section; on (. d fig, 4 - section aa in fig, 3,

The device consists of a drum 1, oil collecting funnels 2, an axial chamber 3, flexible hoses 4, a pipe 5 15 for pumping oil, fittings 6, floats 7, a drive 8 for rotating the drum, a pump unit 9, a side fence 10 with a hinge 11, a pressure pipeline 12 for pumping oil to 20 shore.

The axial chamber 3 includes an axial tube 13 with lower air inlets for air 14 and oil 15 and a tube 16 for removing air 25 atmosphere from the funnel. The axial chamber 3 is fixed motionless with the floats 7 of the device body and does not rotate when the device is operating. The cavity of the axial chamber 3 is connected to the nozzle 5 30 for pumping oil Bariban 1 is made in the form of a squirrel wheel fixed fixedly on the pipe 17, in which the perimeter holes with nozzles 6 are filled around the perimeter. On the outer perimeter of the drum 1 the articulated oil-moving hoppers 2 , oriented vertically and equipped for this purpose with hinges 18. Oil-gathering funnels 2 are filled with lp and suspended in the form of an overturned trough and provided with openings with fittings in the upper part. The fittings 6 in the pipe 17 of the drum 1 are connected by flexible hoses with fittings in the opening of the oil collecting funnel 2, the pipe 17 of the drum 1 is mounted on the axial pipe 13 of the axial chamber 3 with a small clearance, which provides the necessary tightness and the possibility of free rotation of the drum 1 relative to axial chamber 3. The holes 14 of air 14 and oil 15 in the axial pipe 13 of the axial chamber 3 are aligned with the holes in the pipe 17 of the drum 1 in a plane that is perpendicular to the axis of the drum 1 and: the axial chamber 3, the tube 16 for air is fixed Lena rigidly with an axial chamber 3.

The device works as follows.

When the drum 1 of the oil collector is rotated, the funnel 2, hinged on the drum 1, is lowered vertically down onto the surface of the water contaminated with a film of oil. Next, the funnel cuts off a layer of film oil, which, when immersed in the funnel, forces air out of the funnel 2 and through the opening 14 into the tube 16 and into the atmosphere. Film oil is collected in the upper part of the funnel and is sucked into the cavity of the axial chamber 3 through flexible hoses 4, when the hole 15 of the axial pipe 13 and the hole of the choke in the pipe 17 are aligned. Oil is sucked from the cavity of the axial chamber 3 into the oil pumping pipe 5 to receive the pump or in a vacuum tank, the absorption of oil. occurs only at the lower location of the funnel 2 in water, when the holes of the fittings 6 in the pipe 17 of the axial chamber 3 with the hole 15 in the axial pipe 13 of the axial chamber 3 overlap. After the oil is sucked in, the funnel 2 is removed from the water and the drum 1 rotates .

The proposed device is maintained in a floating state by the floats 7. The movement of the device is ensured by the rotation of the drum 1 by the drive 8 located in the compartment of the pump unit 9. The surface area is increased by using side guard 10, the width of the oil film is adjusted by the swivel 11,
