Description

Technical Field

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

[0002] Marine oil spills typically occur during the extraction, transportation, loading, unloading, and use of oil at sea, causing oil pollution. The subsequent handling of marine oil spills involves oil recovery, usually by spraying a gelling agent. This gelling agent is generally a dry, particulate, hydrophobic polymer that reacts with the spilled oil to form tightly bound solid oil slicks that float on the surface, turning the oil spill into scum. This process has advantages such as low toxicity, immunity to wind and waves, and effective prevention of oil spread. The scum is then cleaned up using recovery equipment.

[0003] Most existing recycling devices use conveyor belts to dredge scum from the sea. However, this recycling method has some problems. When the conveyor belt rotates, the dredging plate can easily send seawater into the recycling box, which increases the weight on the top of the floating plate and affects normal use.

[0004] Furthermore, the lack of a drainage mechanism means that as the water inside the recycling device gradually increases, its weight also increases. Therefore, if the time spent cleaning the scum is long, it will affect the balance of the floating plate, which in turn will have a certain impact on the stability of the device.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a marine oil spill scum recovery device, which has the following beneficial effects:

[0018] 1. By setting up a salvage plate, connecting screws, and a conveyor belt, the user can open the conveyor belt to rotate the salvage plate, which is used to salvage floating oil spill debris at sea. The rotation causes the debris to fall into the recycling bin for later collection. During the salvage process, seawater will flow out through the drainage hole to reduce the amount of seawater inside the recycling bin, making it convenient to use. The salvage plate can also be disassembled using the connecting screws for easy cleaning and replacement.

[0019] 2. By installing a drain pipe, a drain pump, and a filter screen, during the salvage process, once the recovery box is filled with water, the user can turn on the drain pump to drain the water from the recovery box through the drain pipe. This reduces the overall weight of the recovery box, prevents it from tipping over due to excessive water, and the filter screen prevents impurities in the seawater from entering the drain pump and affecting it, thus increasing the service life of the device.

[0020] 3. By setting up columns and filter plates, when the scum falls into the inside of the recovery box, the seawater on the oil spill scum will enter the bottom of the recovery box through the filter plates, which is convenient for later discharge. In addition, the filter plates can be pulled out from the inside of the recovery box by pulling rings, so as to facilitate the collection or cleaning of the oil spill scum on the top for subsequent use.

[0031] In this embodiment, a water outlet pipe 12 is fixedly provided on the outer wall and at the bottom of the recycling bin 11. A drain pump 13 is provided at the other end of the water outlet pipe 12, and a drain pipe 14 is provided at the other end of the drain pump 13. A connecting pipe 15 is fixedly provided on the inner wall of the recycling bin 11. The connecting pipe 15 is connected to the water outlet pipe 12. A filter screen 16 is provided on one side of the connecting pipe 15. An internal thread ring 17 is fixedly provided at one end of the filter screen 16. The internal thread ring 17 is threadedly connected to the connecting pipe 15.

[0032] More specifically, the user can open the conveyor belt body 4 to rotate the salvage plate 7 to salvage floating oil spill debris at sea. The rotation causes the debris to fall into the recovery box 11 for subsequent collection. During the salvage process, seawater will flow out from the drain hole 10 to reduce the amount of seawater inside the recovery box 11, making it easier to use. The salvage plate 7 can also be disassembled using the connecting screws 9 for easy cleaning and replacement. During the salvage process, when the recovery box 11 is filled with water, the user can turn on the drain pump 13 to drain the water from the drain pipe 14, reducing the overall weight of the recovery box 11 and preventing it from tipping over due to excessive water. Furthermore, the filter screen 16 prevents impurities in the seawater from entering the drain pump 13, thus preventing damage to the pump and increasing the service life of the device.

[0033] Please see Figure 1 , Figure 2 and Figure 5 As an embodiment for removing the scum from the upper end of the filter plate 21: Columns 18 are fixedly provided on both sides of the inner wall of the recovery box 11. T-shaped grooves 19 are opened on the upper end face of each column 18. T-shaped blocks 20 are slidably provided inside each T-shaped groove 19.

Overlapping blocks 23 are provided on the upper end of each connecting rod 22. The lower end face of each overlapping block 23 is in contact with the upper end face of the recovery box 11. Pull rings 24 are fixedly provided on the upper end face of each overlapping block 23.

[0034] Specifically, when the scum falls into the inside of the recovery box 11, the seawater on the oil spill scum will enter the bottom of the recovery box 11 through the filter plate 21 for easy discharge later. The filter plate 21 can also be pulled out from the inside of the recovery box 11 by the pull ring 24 to facilitate the centralized collection of the oil spill scum on its top.

[0035] Please refer to Figure 1 As a further embodiment of shielding the scum so that it enters the recycling bin 11, an arc-shaped baffle 25 is fixedly provided on the upper surface of the recycling bin 11 and on one side.

[0036] Specifically, this allows the scum to fall into the recycling bin 11, preventing it from flying out.

[0037] In summary, when using the entire equipment: the user can open the conveyor belt body 4 to rotate the salvage plate 7 to salvage floating oil spill debris at sea, and the rotation will cause it to fall into the recovery box 11 for subsequent collection. During the salvage process, seawater will flow out from the drainage hole 10 to reduce the amount of seawater inside the recovery box 11, making it convenient to use. The salvage plate 7 can also be disassembled using the connecting screws 9 for easy cleaning and replacement. During the salvage process, when water fills the recovery box 11, the user can turn on the drainage pump 13 to drain the water. Water inside the tank 11 is discharged through the drain pipe 14 to reduce the overall weight of the recovery tank 11 and prevent it from tipping over due to excessive water. Furthermore, by setting up the filter screen 16, impurities in the seawater can be prevented from entering the drain pump 13, which would affect the sewage pump and increase the service life of the device. When the scum falls into the recovery tank 11, the seawater on the oil spill scum will enter the bottom of the recovery tank 11 through the filter plate 21 for easy discharge later. The filter plate 21 can also be pulled out from the inside of the recovery tank 11 by the pull ring 24 to facilitate the centralized collection of the oil spill scum at its top.
