Description

Technical Field

[0001] The utility model relates to the field of oil pollution treatment, in particular to a water surface oil pollution treatment unit and a treatment device thereof. Background Art

[0002] Crude oil spills are a common occurrence. Leaked oil floats on the water surface, spreading and spreading with the waves. Existing technologies include: First, combustion, but this can cause widespread air pollution and be extremely destructive to aquatic life. Second, adsorption, using oil absorbers and oil-absorbing felt to clean the oil, is a complex process and wastes significant labor. Third, chemical reagents are used, but these reagents cover a large area and can cause secondary pollution, potentially contaminating the aquatic environment. Therefore, we propose a surface oil treatment unit and device.

[0003] Chinese patent document CN117587772A describes a surface oil treatment device and method based on bionic propulsion. The top of the oil treatment vessel is equipped with a discharge drum and a take-up drum. The discharge drum is wrapped with an oil-absorbing cloth, which is then passed down around the bottom of the vessel and then wound onto the take-up drum. The take-up drum is connected to a drive device for reeling. The present invention employs this structure and bionic web-like propulsion to reduce the fragmentation and diffusion of surface oil. The oil-absorbing cloth is continuously treated by the reeling and unreeling method. However, this structure is slow, inefficient, and suffers from incomplete absorption. It is expensive to manufacture, and the recovery mechanism cannot be adjusted up or down. As the vessel collects more oil, the vessel sinks due to gravity, causing the recovery device to collect a large amount of water. This presents drawbacks and requires improvement. Utility Model Content

[0004] The utility model provides a surface oil pollution treatment unit and a treatment device thereof, which solve the problems that the combustion method may cause large-scale air pollution; the adsorption method has a relatively complicated process, wastes a lot of manpower, and has low treatment efficiency; and chemical reagents, but the chemical reagents cover a large area and may also cause secondary pollution.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a surface oil pollution treatment unit, comprising a hull, a lifting oil collecting device provided on the hull, the oil collecting device comprising an oil collecting tank, a plurality of oil suction rollers provided on the oil collecting tank, an oil collecting scraper provided at one end of the oil collecting tank, and a float-type oil-water interface detection device provided at the bottom of the hull;

[0006] The tip of the oil collecting scraper is at the same height as the bottom end of the oil suction roller.

[0007] In a preferred solution, lifting devices are provided on both sides of the hull, and the bottoms of the telescopic ends of the lifting devices are connected to the oil collecting tank.

[0008] In a preferred solution, the lifting device is a worm gear mechanism, a screw nut mechanism or a rack and pinion mechanism.

[0009] In a preferred solution, the oil collecting tank is provided with a plurality of mounting slots connected to the oil collecting tank, the mounting slots are provided with rotating oil suction rollers, and a scraper is provided on one side of the mounting slots, and the scraper rests on the oil suction roller.

[0010] In a preferred solution, a driving device is provided on the oil collecting tank, and the driving device is connected to a plurality of oil suction rollers.

[0011] In a preferred embodiment, the float-type oil-water interface detection device includes a first pull-wire sensor and a second pull-wire sensor, wherein the pull-wire end of the first pull-wire sensor is connected to a first float, and the pull-wire end of the second pull-wire sensor is connected to a second float;

[0012] The density of the first float ball is less than the density of oil, and the density of the second float ball is greater than the density of oil and less than the density of water.

[0013] In the preferred solution, an oil collecting tank is provided on the hull, a connected pump is provided on the oil collecting tank, one end of the pump is connected to the oil collecting tank, and a second interface detection device is provided on the oil collecting tank. The second interface detection device has the same structure as the float type oil-water interface detection device.

[0014] In a preferred solution, a submersible pump is provided on the oil collecting tank, the inlet end of the submersible pump is arranged at the bottom of the oil collecting tank, and the outlet end of the submersible pump is arranged outside the hull.

[0015] The treatment device for a surface oil pollution treatment unit is characterized by comprising two hulls, an oil boom is arranged between the two hulls, the oil boom is provided with a plurality of air bags, the air bags are provided with sealing heads, and the plurality of sealing heads are connected by steel cables;

[0016] A winch is provided on the top of the hull, and the steel cable of the winch passes through the limit frame and is connected to multiple sealing heads.

[0017] In the preferred solution, the winding barrel includes a rotating shaft, a first motor is provided at the bottom of the rotating shaft, the first motor is installed on the hull, a guide frame and a U-shaped limit frame are provided at both ends of one side of the hull, and guide wheels are provided on the limit frame and the guide frame. A winding barrel is provided on the hull, and the two ends of the oil boom are respectively connected to the two winding barrels.

[0018] The beneficial effects of the present invention are as follows: the float-type oil-water interface detection device is used to detect the oil level to determine the lifting height of the lifting device, and to determine the height of the end of the oil collecting scraper and the bottom of the oil suction roller. This prevents the oil collecting scraper and the oil suction roller from being too high, which causes the oil collecting device to fail to collect oil. It also prevents the oil collecting scraper and the oil suction roller from being too low, which causes the oil collected by the oil collecting device to contain a large amount of water, resulting in low collection efficiency of the entire device. The entire device does not pollute the environment, has a high collection efficiency, and absorbs cleanly. When the ship collects more oil, the hull sinks due to gravity and does not collect a large amount of water.

[0019] The float-type oil-water interface detection device uses data from the first and second pull-wire sensors to measure the thickness of the oil, allowing staff to adjust the lifting mechanism to position the bottom of the oil collection device at the oil-water interface. This ensures clean oil removal while minimizing excess water from being collected by the scraper and suction roller into the oil collection silo, reducing the workload of the submersible pump and significantly improving oil treatment efficiency. The second interface detection device detects the oil-water interface within the silo, facilitating drainage.

[0020] The two hulls drive the boom to the shore, then stop and reel in the boom, causing the boom to pull the oil closer to the hull, increasing the thickness of the oil inside the boom. This activates the oil collection devices on the two hulls to collect the oil on the water surface. During the boom reeling process, the scope of the oil is reduced, greatly improving the efficiency of oil treatment.

[0021] Avoid the situation where, during the collection process of the oil pollution device, if there is no obstruction, the oil will still spread from the water surface. Long-term collection will only cause the oil pollution to become thinner, which will cause the oil pollution collection device to work for a long time, resulting in low oil pollution treatment efficiency. At the same time, the oil pollution treatment is not thorough, and a small amount of oil pollution will still float on the water surface. The overall device has a simple structure and can improve collection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] Example 1:

[0034] like Figure 1-9 The invention relates to a surface oil pollution treatment unit and a treatment device thereof, comprising a hull 1, a lifting oil collecting device 2 provided on the hull 1, the oil collecting device 2 comprising an oil collecting tank 201, a plurality of oil suction rollers 4 provided on the oil collecting tank 201, an oil collecting scraper 3 provided at one end of the oil collecting tank 201, and a float-type oil-water interface detection device 8 provided at the bottom of the hull 1;

[0035] The tip of the oil scraper 3 is at the same height as the bottom of the oil suction roller 4. With this structure, a second interface detection device 11 is installed within the oil collection tank 101 within the hull 1. The inlet of the submersible pump is located at the bottom of the oil collection tank 101. When the oil remains stationary for a period of time, it undergoes an oil-water separation phase, remaining above the water. The submersible pump removes excess water collected by the oil collection device 2 during the collection process. When the second float in the oil collection tank 101 reaches the height of the submersible pump's inlet, the submersible pump stops operating, preventing the oil in the oil collection tank 101 from being discharged from the hull 1.

[0036] The float-type oil-water interface detection device 8 is used to detect the oil level to determine the lifting height of the lifting device 5, to determine the height of the end of the oil scraper 3 and the bottom of the oil suction roller 4, to avoid the oil scraper 3 and the oil suction roller 4 being too high, and the oil collecting device 2 being unable to collect oil. At the same time, it avoids the oil scraper 3 and the oil suction roller 4 being too low, and the oil collected by the oil collecting device 2 containing a large amount of water, resulting in low collection efficiency of the entire device.

[0037] The first float 803 floats above the oil surface, and the first pull-wire sensor 801 monitors the position of the hull 1 relative to the oil surface through the position of the first float 803. The second float 804 floats above the water surface and sinks below the oil surface, and the second pull-wire sensor 802 monitors the position of the hull 1 relative to the water surface through the position of the second float 804. The data monitored by the first pull-wire sensor 801 and the second pull-wire sensor 802 can detect the thickness of the oil pollution, making it convenient for the staff to adjust the lifting device 5 so that the bottom of the oil collection device 2 is at the oil-water interface. This ensures that the oil pollution is cleanly removed and also minimizes excessive water from being collected into the oil collection bin 101 by the oil collection scraper 3 and the oil suction roller 4, reducing the workload of the submersible pump, thereby greatly improving the efficiency of oil pollution treatment.

[0038] In the preferred embodiment, lifting devices 5 are provided on both sides of the hull 1, and the bottoms of the telescopic ends of the lifting devices 5 are connected to the oil collection tank 201. With this structure, the lifting devices 5 can be adjusted so that the bottom of the oil collection device 2 is at the oil-water interface. This ensures clean oil removal while minimizing the amount of water collected by the oil scraper 3 and the oil suction roller 4 into the oil collection tank 101, reducing the workload of the submersible pump and significantly improving the efficiency of oil treatment.

[0039] The lifting device 5 can realize the lifting and lowering of the inclined oil scraper 3 and the oil suction roller 4. The lowest ends of the oil scraper 3 and the oil suction roller 4 can be placed on the oil-water interface through lifting and adjustment, and the oil is collected into the oil collecting tank 201 with the water-oil interface as the working interface, thereby achieving clean oil removal and greatly improving the processing efficiency.

[0040] The inclined oil collecting scraper 3 cooperates with the oil suction roller 4 , and the combination of the two can achieve a higher oil collection speed and ensure that the oil collecting scraper 3 does not affect the draft depth of the hull 1 .

[0041] In a preferred embodiment, the lifting device 5 is a worm gear mechanism, a screw nut mechanism or a rack and pinion mechanism. With this structure, the bottom of the lifting device 5 is connected to the oil collecting device 2.

[0042] In the preferred embodiment, the oil collection tank 201 is provided with a plurality of mounting slots 202 connected to the oil collection tank 201. Rotating oil suction rollers 4 are mounted on the mounting slots 202. Scrapers 203 are provided on one side of the mounting slots 202, and the scrapers 203 abut against the oil suction rollers 4. With this structure, the second motor is driven to rotate the oil suction rollers 4, and the scrapers 203 scrape the oil off the oil suction rollers 4.

[0043] In a preferred embodiment, a drive device 6 is provided on the oil collection tank 201 and is connected to the plurality of oil suction rollers 4. With this structure, the drive device 6 includes a second motor and a three-axis angler. One end of the three-axis angler is connected to the second motor, and the other two ends of the three-axis angler are connected to the oil suction rollers 4. The oil suction rollers 4 are rotatably connected to the mounting trough 202, driving the second motor to rotate the oil suction rollers 4.

[0044] In a preferred embodiment, the float-type oil-water interface detection device 8 includes a first pull-wire sensor 801 and a second pull-wire sensor 802. The pull-wire end of the first pull-wire sensor 801 is connected to a first float 803, and the pull-wire end of the second pull-wire sensor 802 is connected to a second float 804.

[0045] The density of the first float 803 is less than that of oil, while the density of the second float 804 is greater than that of oil but less than that of water. With this structure, the first float 803 floats above the oil surface, and the first pull-wire sensor 801 monitors the position of the hull 1 relative to the oil surface through the position of the first float 803. The second float 804 floats above the water surface but sinks below the oil surface, and the second pull-wire sensor 802 monitors the position of the hull 1 relative to the water surface through the position of the second float 804. The data monitored by the first and second pull-wire sensors 801, 802 can detect the thickness of the oil stain, making it easier for staff to adjust the lifting device 5.

[0046] In the preferred embodiment, hull 1 is provided with an oil collection tank 101, which is connected to a pump 12. One end of pump 12 is connected to oil collection tank 201. Oil collection tank 101 is also provided with a second interface detection device 11, which has the same structure as the float-type oil-water interface detection device 8. With this structure, pump 12 transports oil from oil collection tank 201 to oil collection tank 101. Once the oil settles in oil collection tank 101, allowing the oil to float on the surface of the water, the submersible pump removes excess water from oil collection tank 101 and drains it out of hull 1.

[0047] In a preferred embodiment, a submersible pump is installed in the oil collection tank 101. The inlet of the submersible pump is located at the bottom of the oil collection tank 101, and the outlet of the submersible pump is located outside the hull 1. With this structure, a second interface detection device 11 is installed in the oil collection tank 101 within the hull 1, and the inlet of the submersible pump is located at the bottom of the oil collection tank 101. When the oil remains stationary for a period of time, it enters the oil-water separation stage, where the oil is located above the water. The submersible pump drains excess water collected by the oil collection device 2 during the collection process. When the second float in the oil collection tank 101 reaches the height of the submersible pump's inlet, the submersible pump stops operating to prevent the oil in the oil collection tank 101 from being discharged into the hull 1.

[0048] Example 2:

[0049] Further illustrate with reference to Example 1:

[0050] This device, used in a surface oil pollution treatment unit, is characterized by comprising two hulls 1, with an oil boom 7 positioned between them. The boom 7 is equipped with multiple airbags 701, each equipped with a plugging head 702. The plugging heads 702 are connected by a steel cable 10. A winch 9 is positioned atop the hulls 1, and the steel cable 10 of the winch 9 passes through a stopper 104 and connects to the plugging heads 702. This structure allows a guide frame 106 to facilitate movement of the boom 7 during reeling, preventing collision between the boom 7 and the hull 1. The stopper 104 limits the position of the steel cable 10 and provides tension to the steel cable 10.

[0051] The reel drum 102 includes a rotating shaft 103, with a first motor 105 mounted at its base. The motor 105 is mounted on the hull 1. One side of the hull 1 is equipped with a guide rail 106 and a U-shaped stopper 104, each with a guide wheel. Both the stopper 104 and the guide rail 106 are equipped with guide wheels. The reel drum 102 is mounted on the hull 1, and the ends of the oil boom 7 are connected to the two reel drums 102. With this structure, the oil boom 7 passes through a gap in the hull 1 and is mounted on the reel drum 102. The sealing head 702 is made of rubber.

[0052] The two hulls 1 are combined with the oil boom 7 to drive the first motor 105 on the hull 1 to reel the oil boom 7, and at the same time drive the winch 9 to reel in both ends of the oil boom 7. At the same time, when the end of the oil boom 7 moves to the bottom of the limit frame 104, the sealing head 702 at the end is pulled out from the oil boom 7 under the tension of the steel cable 10 to deflate the airbag 701. After that, when the oil boom 7 passes through the gap of the hull 1, the gap of the hull 1 clamps the oil boom 7 to completely deflate the airbag 701, so that the oil boom 7 can be reeled in.

[0053] The two hulls 1 drive the oil boom 7 to the shore, then stop moving and drive the reel drum 102 to reel. This allows the boom 7 to pull the oil closer to the hull 1, increasing the thickness of the oil within the boom 7. The oil collection devices 2 on the two hulls 1 are then driven to collect the oil on the water surface. During the reeling of the boom 7, the scope of the oil is reduced, greatly improving the efficiency of oil treatment.

[0054] Avoid the situation where, during the collection process of the oil pollution device, if there is no obstruction, the oil will still spread from the water surface. Long-term collection will only cause the oil pollution to become thinner, which will cause the oil pollution collection device to work for a long time, resulting in low oil pollution treatment efficiency. At the same time, the oil pollution treatment is not thorough, and a small amount of oil pollution will still float on the water surface. The overall device has a simple structure and can improve collection efficiency.

The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims.
