Description

Technical Field

[0001] This utility model relates to the technical field of anti-clogging devices, specifically an oil removal and anti-clogging device for offshore platforms. Background Technology

[0002] The offshore platform oil removal and anti-clogging device employs multi-stage filtration and cyclone separation technology, achieving efficient oil-water separation through gravity settling, adsorption by coalescing materials, and centrifugal separation. Its core components include a self-cleaning oil skimming system and anti-scaling coated pipes, coupled with differential pressure sensors to monitor clogging risks in real time. When the oil concentration exceeds a threshold, a backflushing procedure is automatically triggered. The device integrates AI algorithms to dynamically adjust separation parameters, adapting to different oil content conditions. Its modular design facilitates maintenance, and key components are equipped with electric heating systems to prevent low-temperature solidification, ensuring continuous and stable operation even in harsh sea conditions.

[0003] During the production process on offshore platforms, impurities such as sand, rust, and large oil sludge generated in the production process can easily enter related equipment. Existing technologies lack effective means of interception at the source, making these impurities prone to clogging the equipment. Furthermore, when cleaning the filter structure, it is difficult to achieve precise control of the horizontal movement of the cleaning components, flexible adjustment of the cleaning height, and all-round cleaning rotation, making it impossible to effectively remove impurities attached to the filter structure. At the same time, there is a lack of effective ways to further remove residual impurities on the surface of the filter structure, affecting the normal operation of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an oil removal and anti-clogging device for offshore platforms, which solves the problems mentioned in the background art, such as impurities easily causing device clogging, inability to effectively remove impurities attached to the filter structure, and lack of effective methods to further remove residual impurities on the surface of the filter structure, thus affecting the normal operation of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil removal and anti-clogging device for offshore platforms, comprising:

[0006] The anti-clogging device housing has a filter screen installed at its inlet and a mounting bracket installed on its surface.

[0007] A first driving component is disposed on the surface of the mounting bracket. A transmission component is mounted on the output end of the first driving component, and a moving component is mounted on the surface of the transmission component.

[0008] A second driving component is disposed on the surface of the moving component. A third driving component is installed at the output end of the second driving component, and a cleaning component is installed at the output end of the third driving component.

[0009] A flushing element is disposed on the surface of the anti-clogging device housing, and a flushing plate is mounted on the surface of the flushing element.

[0010] Preferably, a guide is mounted on the surface of the movable component, and a guide connector is mounted on the surface of the mounting bracket at a position corresponding to the guide. The guide is a slider, and the guide connector is a guide rail. The guide is movably mounted inside the guide connector so that the movable component can move linearly.

[0011] Preferably, an oil-water separation module is installed inside the shell of the anti-clogging device. A vibrating element is installed on the surface of the oil-water separation module. The oil-water separation module forms a high specific surface area separation interface through an inclined plate structure covered by a hydrophilic and oleophobic membrane. By utilizing the density difference between oil and water and the difference in surface properties of the membrane material, crude oil agglomerates into large oil droplets on the inclined plate surface and then quickly floats to the oil discharge area. At the same time, the water phase penetrates the membrane layer and flows downward, achieving efficient oil-water separation. The vibrating element is an ultrasonic vibration generator, which can vibrate and clean the oil-water separation module.

[0012] Preferably, positioning elements are installed at all four corners of the upper surface of the filter screen. The positioning elements penetrate the surface of the filter screen frame and are installed on the surface of the anti-clogging device housing. The positioning elements are bolts, which facilitate the installation and removal of the filter screen.

[0013] Preferably, a regulating valve is installed at the outlet of the anti-clogging device housing, and a conveying component is installed at the outlet of the regulating valve. The regulating valve is a flow regulating valve used to control the oil discharge speed and prevent crude oil entrainment, and the conveying component is an oil pipeline.

[0014] Preferably, a flow guide is installed in the lower part of the inner cavity of the anti-clogging device housing. The outlet of the flow guide is connected to the inlet of the regulating valve. The flow guide is funnel-shaped and can inject oil from the anti-clogging device housing into the regulating valve.

[0015] Compared with the prior art, this utility model provides an oil removal and anti-clogging device for offshore platforms, which has the following beneficial effects:

[0016] This offshore platform oil removal and anti-clogging device features a filter screen with precision pore size that intercepts impurities such as sand, rust, and large oil sludge particles during production, reducing the possibility of clogging at the source. The first drive component uses a stepper motor, which, in conjunction with a lead screw, precisely moves the moving component, providing a stable horizontal foundation for subsequent cleaning operations. The second drive component is a cylinder, which can flexibly adjust the height of the cleaning component. The third drive component is a motor that drives the cleaning brush to rotate, cleaning the filter screen from all angles and effectively removing attached impurities. The rinsing component uses a rinsing pump, which rinses the surface of the filter screen through a rinsing plate to further remove residual impurities. The synergistic effect of these multiple structures effectively prevents filter screen clogging and ensures the normal operation of the device. Attached Figure Description

[0022] This utility model provides a technical solution: an oil removal and anti-clogging device for offshore platforms. Please refer to [link / reference]. Figure 1 It includes an anti-clogging device housing 1, a filter screen 2 installed at the inlet of the anti-clogging device housing 1, and a mounting bracket 3 installed on the surface of the anti-clogging device housing 1;

[0023] Filter screen 2 intercepts impurities in production, such as sand, rust, and large particles of sludge, through its precision aperture.

[0024] A first driving component 4 is disposed on the surface of the mounting bracket 3. A transmission component 5 is mounted on the output end of the first driving component 4, and a moving component 6 is mounted on the surface of the transmission component 5. The first driving component 4 is a stepper motor, and the transmission component 5 is a lead screw. Activating the first driving component 4 can drive the transmission component 5 to rotate, thereby driving the moving component 6 to move.

The output end of the second driving component 7 is equipped with a third driving component 8, and the output end of the third driving component 8 is equipped with a cleaning component 9. The second driving component 7 is a cylinder, the third driving component 8 is a motor, and the cleaning component 9 is a cleaning brush. The height of the cleaning component 9 can be adjusted by the second driving component 7, and the third driving component 8 can be started to drive the cleaning component 9 to rotate and clean the filter screen 2.

[0026] Please see Figure 2 The flushing component 10 is disposed on the surface of the anti-clogging device housing 1. A flushing plate 11 is installed on the surface of the flushing component 10. The flushing component 10 is a flushing pump. When the flushing component 10 is started, the surface of the filter screen 2 can be flushed through the flushing plate 11.

[0027] The filter screen 2 intercepts impurities such as sand, rust, and large oil sludge particles during production through its precise aperture, reducing the possibility of clogging at the source. The first drive component 4 uses a stepper motor, which, together with the lead screw of the transmission component 5, can precisely drive the moving component 6 to move, providing a stable horizontal movement foundation for subsequent cleaning work. The second drive component 7 is a cylinder that can flexibly adjust the height of the cleaning component 9. The third drive component 8 is a motor that drives the cleaning component 9, i.e., the cleaning brush, to rotate, which can clean the filter screen 2 from all directions and effectively remove attached impurities. The rinsing component 10 uses a rinsing pump to rinse the surface of the filter screen 2 through the rinsing plate 11, further removing residual impurities. The synergistic effect of these multiple structures effectively prevents the filter screen 2 from clogging and ensures the normal operation of the device.

[0028] The surface of the movable part 6 is equipped with a guide 12, and the surface of the mounting bracket 3 is equipped with a guide connector 13 at the corresponding position of the guide 12. The guide 12 is a slider, and the guide connector 13 is a guide rail. The guide 12 is movably installed inside the guide connector 13 so that the movable part 6 can move linearly.

[0029] Please see Figure 3 The anti-clogging device housing 1 houses an oil-water separation module 14. A vibrating element 15 is installed on the surface of the oil-water separation module 14. The oil-water separation module 14 forms a high specific surface area separation interface through an inclined plate structure covered by a hydrophilic and oleophobic membrane. By utilizing the density difference between oil and water and the difference in surface properties of the membrane material, crude oil agglomerates into large oil droplets on the inclined plate surface and then quickly floats to the oil discharge area. At the same time, the water phase penetrates the membrane layer and flows downward, achieving efficient oil-water separation. The vibrating element 15 is an ultrasonic vibration generator that can vibrate and clean the oil-water separation module 14.

[0030] Positioning elements 16 are installed at the four corners of the upper surface of the filter screen 2. The positioning elements 16 penetrate the surface of the outer frame of the filter screen 2 and are installed on the surface of the anti-clogging device housing 1. The positioning elements 16 are bolts, which facilitate the disassembly and assembly of the filter screen 2.

[0031] The outlet of the anti-clogging device housing 1 is equipped with a regulating valve 17, and the outlet of the regulating valve 17 is equipped with a conveying component 18. The regulating valve 17 is a flow regulating valve used to control the oil discharge speed and prevent crude oil entrainment, and the conveying component 18 is an oil conveying pipeline.

[0032] A guide 19 is installed in the lower part of the inner cavity of the anti-clogging device housing 1. The outlet of the guide 19 is connected to the inlet of the regulating valve 17. The guide 19 is funnel-shaped and can inject the oil in the anti-clogging device housing 1 into the regulating valve 17.

[0033] In operation, the oil-water mixture from production enters through the inlet of the anti-clogging device housing 1, and passes through the filter screen 2 installed on it, where it intercepts impurities such as sand, rust, and large oil sludge particles through precise apertures. The first drive component 4, i.e., the stepper motor, mounted on the mounting frame 3, is activated, driving the transmission component 5, i.e., the lead screw, to rotate, which in turn drives the moving component 6 to move. The moving component 6 moves linearly under the action of the guide component 12, i.e., the slider, and the guide connecting component 13, i.e., the guide rail. During the movement of the moving component 6, the second drive component 7, i.e., the cylinder, on its surface is activated to adjust the height of the cleaning component 9, i.e., the cleaning brush. Then, the third drive component 8, i.e., the motor, drives the cleaning brush to rotate and clean the filter screen 2. When the flushing pump 10, which is installed on the surface of the anti-clogging device housing 1, is activated, the surface of the filter screen 2 is flushed through the flushing plate 11. Then, the oil-water mixture enters the oil-water separation module 14 inside the anti-clogging device housing 1. The oil and water are separated by the inclined plate structure covered by the hydrophilic and oleophobic film. The vibrating component 15, which is the ultrasonic vibration generator, vibrates and cleans the oil-water separation module 14. The separated oil is injected into the regulating valve 17, which is the flow regulating valve, through the guide component 19, which is the funnel-shaped design structure at the bottom of the inner cavity of the anti-clogging device housing 1. The oil discharge speed is controlled by the regulating valve 17 to prevent crude oil entrainment. Finally, the oil is transported out through the conveying component 18, which is the oil pipeline.
