Description

Technical Field

[0001] This utility model relates to the field of oil removal device technology, and in particular to an oil removal device for offshore platforms. Background Technology

[0002] Offshore platform oil removal devices are commonly used on offshore oil platforms to separate and remove oil from wastewater, oil-water mixtures, and other pollution sources to protect the marine environment and meet emission standards. Offshore platform oil removal devices include air flotation devices, which mainly work by injecting microbubbles into the wastewater, causing oil droplets to float to the surface and form an oil layer, making them easier to remove. When the bubbles come into contact with the oil-water mixture in the liquid, the bubbles adhere to the surface of the oil droplets. Due to the buoyancy of the oil and the bubbles, the oil droplets float up with the bubbles. After the oil droplets are encased by the bubbles, the buoyancy generated causes the oil droplets to float to the surface. Most of the oil in the water has been removed by the buoyancy of the bubbles.

[0003] While the generation of bubbles helps separate oil and water, bubbles may aggregate into larger bubbles, affecting the separation effect and reducing separation efficiency. This reduces the contact opportunities between bubbles and oil droplets, thus lowering the efficiency of oil-water separation. Therefore, it is particularly important to design an oil removal device for offshore platforms, which increases the contact area between the oil and water by continuously agitating them. Utility Model Content

[0004] The purpose of this invention is to provide an oil removal device for offshore platforms, which solves the problem mentioned in the background art that bubbles may aggregate into larger bubbles, affecting the separation effect, reducing separation efficiency, and decreasing the contact opportunities between bubbles and oil droplets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil removal device for offshore platforms, comprising an air flotation tank and a compressed air bubble generator. The compressed air bubble generator is disposed on one side of the air flotation tank. A support rod is disposed inside the air flotation tank. A support block is sleeved on one end of the support rod. An extension rod is disposed on one side of the support block. An extension plate is disposed on one end of the extension rod. Two screws are movably connected inside the extension plate. A positioning rod is disposed on one end of each of the two screws. Multiple vertical rods are disposed at the bottom of each of the two positioning rods. A stirring plate is disposed on one end of each of the multiple vertical rods. A straight toothed rack is fixedly installed on one side of the support block.

[0006] As a preferred embodiment of this utility model, a motor is provided on one side of the flotation tank, and the support block is movably sleeved with one end of the support rod.

[0007] As a preferred embodiment of this utility model, the output shaft of the motor is connected to a gear, and the gear meshes with a straight rack.

[0008] As a preferred embodiment of this utility model, the tops of the plurality of stirring plates are respectively fixedly connected to one end of the plurality of vertical rods, and one end of each of the two screws is threaded with a limiting nut.

[0009] In a preferred embodiment of this invention, the multiple stirring plates are arranged at equal intervals.

[0010] As a preferred embodiment of this utility model, a limiting block is fixedly installed on the top of the straight rack, and a concave hole is provided on one side of the flotation tank.

[0011] As a preferred technical solution of this utility model, a limiting strip is provided on one side of the limiting block, and one end of the limiting strip is connected to the internal thread of the concave hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model incorporates a support block, motor, gears, a straight rack, a vertical rod, and stirring plates. Oil and water are guided into the flotation tank. With the activation of the compressed air bubble generator, bubbles are injected into the oil and water, causing oil particles to float to the surface and form an oil layer. Simultaneously, the motor is activated, driving the gear connected to its output shaft to rotate synchronously. This, in turn, causes the straight rack, which meshes with the gear, to move left and right. The support block can then move left and right at one end of the support rod. With the connection of the extension rod, multiple stirring plates also move left and right inside the flotation tank. The stirring of the oil, water, and bubbles by the multiple stirring plates increases the contact opportunity between the bubbles and oil particles, thus improving the efficiency of oil-water separation.

[0014] 2. This utility model incorporates an extension rod, an extension plate, a screw, a limiting strip, a recessed hole, and a limiting nut. By rotating the limiting nut in the opposite direction, it disengages from one end of the screw. Moving the positioning rod to one side separates it from the extension plate, allowing multiple mixing plates to be individually removed from the flotation tank for subsequent cleaning. When positioning the extension rod is required, one end of the limiting strip is inserted into the recessed hole. The threaded connection between the two secures the flotation tank and the support block. The limiting of the gear and straight rack prevents them from disengaging, extending the service life of the structure. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution for an oil removal device for offshore platforms:

[0023] Example 1:

[0024] like Figure 1-4 As shown, an oil removal device for an offshore platform includes a flotation tank 1 and a compressed air bubble generator 2. The compressed air bubble generator 2 is located on one side of the flotation tank 1. A support rod 3 is installed inside the flotation tank 1. A support block 4 is fitted onto one end of the support rod 3. An extension rod 5 is installed on one side of the support block 4. An extension plate 6 is installed at one end of the extension rod 5. Two screws 7 are movably connected inside the extension plate 6. A positioning rod 8 is installed at one end of each of the two screws 7. Multiple vertical rods 10 are installed at the bottom of each of the two positioning rods 8. Each end is equipped with a stirring plate 11, and a straight rack 14 is fixedly installed on one side of the support block 4. When the motor 12 is started, it drives the gear 13, which is connected to its output shaft, to rotate synchronously. This drives the straight rack 14, which is meshed with it, to move left and right. The support block 4 can then move left and right at one end of the support rod 3. With the connection of the extension rod 5, multiple stirring plates 11 will also move left and right inside the flotation tank 1. By stirring the oil, water and air bubbles with multiple stirring plates 11, the contact opportunity between air bubbles and oil particles is increased, thereby improving the efficiency of oil-water separation.

[0025] Example 2:

[0026] Based on Example 1, such as Figure 1 and Figure 5 As shown, a limiting block 15 is fixedly installed on the top of the straight rack 14. A recessed hole is opened on one side of the flotation tank 1, and a limiting strip 16 is provided on one side of the limiting block 15. One end of the limiting strip 16 is threadedly connected to the inside of the recessed hole. By setting up an extension rod 5, an extension plate 6, a screw 7, a limiting strip 16, a recessed hole, and a limiting nut 9, the limiting nut 9 is rotated in the opposite direction to disengage it from one end of the screw 7. The positioning rod 8 is moved to one side to separate it from the extension plate 6, so that multiple stirring plates 11 can be removed from the inside of the flotation tank 1 for subsequent cleaning. When it is necessary to position the extension rod 5, one end of the limiting strip 16 is embedded into the inside of the recessed hole. With the threaded connection between the two, the flotation tank 1 and the support block 4 can be fixed.

[0027] Working Principle: Offshore platform oil removal devices are commonly used on offshore oil platforms to separate and remove oil from wastewater, oil-water mixtures, and other pollution sources to protect the marine environment and meet emission standards. These devices include an air flotation unit. The air flotation unit primarily works by injecting microbubbles into the wastewater, causing oil droplets to float to the surface and form an oil layer, facilitating removal. When the bubbles come into contact with the oil-water mixture in the liquid, bubbles adhere to the surface of the oil droplets. Due to the buoyancy of the oil and bubbles, the oil droplets rise with the bubbles. Once the oil droplets are encapsulated by the bubbles, the resulting buoyancy causes them to float to the surface. Most of the oil in the water has already been removed by the buoyancy of the bubbles. While bubble generation helps separate oil and water, bubbles may aggregate into larger bubbles, affecting the separation effect and reducing efficiency. This reduces the contact opportunity between bubbles and oil droplets, thus lowering the oil-water separation efficiency. Therefore, designing an offshore platform oil removal device is crucial. Continuous agitation of the oil and water increases their contact area. The oil and water are guided into the air flotation tank 1, where compressed air bubbles... When generator 2 is started, air bubbles are injected into the oil-water mixture, causing oil droplets to float to the surface and form an oil layer. Simultaneously, motor 12 is started, driving gear 13, which is connected to its output shaft, to rotate synchronously. This, in turn, causes the straight rack 14, which meshes with it, to move left and right. Support block 4 can then move left and right at one end of support rod 3. Connected by extension rod 5, multiple stirring plates 11 also move left and right inside the flotation tank 1. Through the stirring of oil, water, and air bubbles by the multiple stirring plates 11, the contact opportunity between air bubbles and oil droplets is increased, improving oil-water separation. To improve efficiency, the limiting nut 9 is rotated in the opposite direction to disengage it from one end of the screw 7. The positioning rod 8 is moved to one side to separate it from the extension plate 6, allowing multiple stirring plates 11 to be removed from the interior of the flotation tank 1 for subsequent cleaning. When the extension rod 5 needs to be positioned, one end of the limiting strip 16 is inserted into the recessed hole. With the threaded connection between the two, the flotation tank 1 and the support block 4 can be fixed. By limiting the gear 13 and the straight rack 14, the two can be prevented from separating, thus extending the service life of the structure.
