Description

Technical Field

[0001] This utility model relates to the field of environmental treatment technology, and more specifically, it relates to a marine oil spill pollution treatment and recovery device. Background Technology

[0002] Oil tankers may leak oil during transport due to collisions, groundings, equipment failures, or other reasons. Marine oil spills are a serious environmental disaster. Oil spills cover the ocean surface, affecting the photosynthesis of phytoplankton and thus the entire food chain. Toxic substances in oil can directly poison marine life, causing the death of large numbers of fish, seabirds, dolphins, and other species. Oil spills can also pollute beaches and coastlines, affecting the survival of marine plants and benthic organisms. Harmful substances in oil spills may enter the human body through the food chain, posing a threat to human health.

[0003] Existing marine crude oil spill collection devices collect spilled oil by sucking up the floating oil and then separating it from the water. However, when sucking up the floating oil, the suction head is directly inserted into the sea surface and easily absorbs a large amount of seawater, resulting in low collection efficiency of the spilled crude oil. At the same time, the filter device on the suction head is easy to get clogged, making it inconvenient to replace and clean the suction head. The floating frame for cleaning up the spilled crude oil is also difficult to move on the sea surface. Utility Model Content

One end of the connecting annular groove 9 is connected to the suction head 7 and is connected to a feed chute 10. The other end is circumferentially equipped with a suction chute 11. A filter screen 12 is installed on the annular block 8. The power guiding device includes an oil boom 13. The oil boom 13 is symmetrically arranged on one side of the floating frame 2. A power frame 14 is provided on one side of the oil boom 13. The power frame 14 is equipped with a first motor 15 and a propeller 16. A transmission sprocket 17 and a transmission chain 18 are provided between the first motor 15 and the propeller 16. A counterweight block 20 is provided at the bottom of the suction head 7. A connecting ring 21 is provided on the suction head 7. Multiple floats 22 are circumferentially arranged on the connecting ring 21.

[0030] In this embodiment, during use, the suction head 7 is placed in the crude oil-polluted sea surface. The top of the annular block 8 is facing upwards by the counterweight 20. Through the connecting ring 21 and the float 22, in conjunction with the counterweight 20, the suction trough 11 of the suction head 7 is positioned at the oil-water interface. The pump body 5 is started to extract the oil-water mixture. The oil and water enter the connecting ring groove 9 through the suction trough 11 and enter the suction head 7 through the feed trough 10. Subsequently, after passing through the oil-water separator 3, the seawater is discharged, and the raw material is stored in the crude oil collection tank 4, completing the oil-water treatment and recycling. The filter screen 12 prevents impurities from entering the suction head 7. The oil boom 13 is used to fence off the oil-water collection area to prevent the oil and water from being washed away.

The limiting plate 29 of the insertion tube 28 of the suction head 7 is aligned with the limiting groove 30 and inserted into the second external threaded tube 26. The sealing ring 31 improves the connection sealing. Then, the internal threaded sleeve 27 is rotated so that half of the internal threaded sleeve 27 is on the first external threaded tube 25 and the other half is on the second external threaded tube 26, thereby connecting the suction head 7 and the connecting tube 6, improving the ease of installation of the suction head 7.

[0033] In summary, during the use or operation of the overall equipment: When in use, the suction head 7 is placed in the oil-polluted sea surface. The counterweight 20 ensures the top of the annular block 8 faces upwards. Through the connecting ring 21 and the float 22, in conjunction with the counterweight 20, the suction trough 11 of the suction head 7 is positioned at the oil-water interface. The pump body 5 is started to extract the oil-water mixture. The oil and water enter the connecting ring groove 9 through the suction trough 11 and then enter the suction head 7 through the feed trough 10. Subsequently, the mixture passes through the oil-water separator 3, which separates the oil and water... Seawater is discharged, and the raw materials are stored in the crude oil collection tank 4 to complete the oil and water treatment and recycling. The filter screen 12 prevents impurities from entering the suction head 7. The oil and water collection area is fenced off by the oil boom 13 to prevent the oil and water from being washed away. The first motor 15 drives the propeller 16 to rotate through the cooperation of the transmission chain 18 and the transmission sprocket 17, which drives the floating frame 2 to move. The second motor 23 drives the guide vane 24 to rotate, which adjusts the direction of movement of the floating frame 2.

[0034] When installing the suction head 7, the filter screen 12 is installed on the suction head 7 through the installation ring 19. The limiting plate 29 of the insertion tube 28 of the suction head 7 is aligned with the limiting groove 30 and inserted into the second external threaded tube 26. The sealing ring 31 improves the connection sealing. Then, the internal threaded sleeve 27 is rotated so that half of the internal threaded sleeve 27 is on the first external threaded tube 25 and the other half is on the second external threaded tube 26, thereby connecting the suction head 7 and the connecting tube 6, which improves the ease of installation of the suction head 7.
