DETAILED DESCRIPTION OF THE INVENTION
In the following detailed description of the invention, reference numerals are used to identify structural elements, portions of elements, or surfaces in the drawings, as such elements, portions or surfaces may be further described or explained by the entire written specification. For consistency, whenever the same numeral is used in different drawings, it indicates the same element, portion, surface and area as when first used. It should be understood that only those components having particular functional importance or that would not otherwise be identified have been assigned reference numerals.
Referring generally to the figures, a floating machine for retrieving oil from a body of water comprises a sloped platform 10 suspended between two elongated hollow cylinders 12, 14. One cylinder runs parallel to each of the opposed longitudinal edges of the sloped platform. Each of the cylinders includes cylinder rotation means 16 at one or both ends for effecting rotation about its longitudinal axis. The cylinder rotation means are in communication with a motor (not shown) which transmits the rotational force to the hollow cylinders.
A plurality of elongated bands 18 is suspended in parallel arrangement along the length of each of the cylinders. Each band is manufactured of a flexible plastic. The internal face 20 of each band has a textured surface to increase surface tension to permit releasable gripping of the band by the cylinder. Accordingly, rotation of the cylinder causes rotation of each of the bands. The external face 22 of each band is coated with clear coat paint. The surface qualities of the external face of each band enable the band to retain a coating of oil when the band is passed through floating oil.
Adjacent the inner side of each cylinder there is provided an elongated blade 24 for mechanical scraping of the oil coating from each band as the band is rotated past the blade. The released oil flows across the top surface of each blade, into the sloped platform 10, and down the slope into an oil collection container 26 provided.
For example, an oil barrel may be used to collect the retrieved oil. The machine further comprises a cover surface 28 for preventing entry of precipitation, debris, insects or animals into the sloped platform.
In operation, the machine is barged into position and anchored in a contaminated water body 34 having floating oil 36. The motor is started to drive rotation of the cylinders. As each cylinder rotates, the plurality of bands arrayed along its length is caused to rotate into the water through the surface oil and back out into the air.
In the following detailed description of the invention, reference numerals are used to identify structural elements, portions of elements, or surfaces in the drawings, as such elements, portions or surfaces may be further described or explained by the entire written specification. For consistency, whenever the same numeral is used in different drawings, it indicates the same element, portion, surface and area as when first used. It should be understood that only those components having particular functional importance or that would not otherwise be identified have been assigned reference numerals.
Referring generally to the figures, a floating machine for retrieving oil from a body of water comprises a sloped platform 10 suspended between two elongated hollow cylinders 12, 14. One cylinder runs parallel to each of the opposed longitudinal edges of the sloped platform. Each of the cylinders includes cylinder rotation means 16 at one or both ends for effecting rotation about its longitudinal axis. The cylinder rotation means are in communication with a motor (not shown) which transmits the rotational force to the hollow cylinders.
A plurality of elongated bands 18 is suspended in parallel arrangement along the length of each of the cylinders. Each band is manufactured of a flexible plastic. The internal face 20 of each band has a textured surface to increase surface tension to permit releasable gripping of the band by the cylinder. Accordingly, rotation of the cylinder causes rotation of each of the bands. The external face 22 of each band is coated with clear coat paint. The surface qualities of the external face of each band enable the band to retain a coating of oil when the band is passed through floating oil.
Adjacent the inner side of each cylinder there is provided an elongated blade 24 for mechanical scraping of the oil coating from each band as the band is rotated past the blade. The released oil flows across the top surface of each blade, into the sloped platform 10, and down the slope into an oil collection container 26 provided.
For example, an oil barrel may be used to collect the retrieved oil. The machine further comprises a cover surface 28 for preventing entry of precipitation, debris, insects or animals into the sloped platform.
In operation, the machine is barged into position and anchored in a contaminated water body 34 having floating oil 36. The motor is started to drive rotation of the cylinders. As each cylinder rotates, the plurality of bands arrayed along its length is caused to rotate into the water through the surface oil and back out into the air.
5 As best seen in Fig. 4, upon exiting the oily surface, each band will have an oil coating 30 on its outer face. Continuing rotation will draw the band in close proximity along the edge of the blade, effecting release of the oil coating. The released oil 32 will flow into the sloped platform and down the slope into the oil container for temporary storage.
Once the oil containers are full, the machine may be retrieved for emptying of the retrieved oil, and returned to service.
In one embodiment, each cylinder may contain pressurized gas and means for underwater release of the gas. The released pressurized gas may be used to dislodge oil particles which may be more firmly attached to underwater plants or debris.
While in the preferred embodiment the oil collection occurs in a central platform between two rotating cylinders, the invention also contemplates a pair of central cylinders expelling their oil coating into collection platforms and containers located peripherally.
While the flotation required for operation of the machine may be obtained from the rotating cylinders, in one embodiment there are provided additional flotation devices to aid in buoyancy.
The present invention may be used in calm waters such as tailings ponds, or in turbulent water bodies such as open oceans.
In a preferred embodiment, the sloped platform comprises a central peak sloping downwardly to opposing ends. However, other slope formations are also contemplated, including a single slope extending from one end of the platform to the opposite end.
In one embodiment, each cylinder may be 12 feet long and 12 inches in diameter.
Cylinders may be shorter or longer and of different diameters.
