[0002] The main causes of oil spill accidents on water include oil well pollution, oil loading and unloading pollution, oil spills from ship accidents, natural disasters, etc.; oil spills on water will form an oil film on the sea surface, which will hinder the photosynthesis of marine phytoplankton and water-gas exchange, reduce the dissolved oxygen content in the water, and thus cause seawater environmental pollution.

[0003] Traditional physical oil spill treatment methods include fencing, oil skimmers, ship-borne oil collection systems, oil spill recovery vessels, etc. The fencing method is only used to prevent the spread of oil on the water surface; oil skimmers have disadvantages such as high water content in the recovered oil-water mixture and the recovery efficiency is easily affected by the environment; ship-borne oil collection systems and oil spill recovery vessels are mostly used for large-scale oil spill treatment, and their flexibility of use and collection efficiency need to be improved.

[0004] The hub-type oil skimmer used in the prior art separates oil and water through an oleophilic and hydrophobic layer coated on the hub, and then uses a scraper to scrape off the recovered oil on the oleophilic and hydrophobic layer to achieve oil spill recovery and environmental purification. Although this improves the flexibility of use and collection efficiency, the scraper is fixedly installed. When the oleophilic and hydrophobic layer and the scraper are worn, the gap will become larger, affecting the scraping effect. In addition, the viscosity of the recovered oil is different, and it is impossible to maintain sufficient tightness on the scraper.

[0005] Therefore, in order to solve the above problems, a hub-type oil skimmer is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 4The utility model provides a hub type oil collecting machine, comprising a frame 1, wherein a longitudinal beam 3 is fixedly installed inside the frame 1, the longitudinal beam 3 divides the frame 1 into a right oil collecting chamber and a left oil storage chamber, a cross beam 5 is fixedly installed inside the oil collecting chamber, the cross beam 5 divides the oil collecting chamber into an oil collecting chamber, an oil collecting plate 9 is fixedly installed at the bottom of the oil collecting chamber, the oil collecting plate 9 is provided with a through groove, the edge of the through groove is fixedly installed with an upper flange 15, a wheel hub 13 is rotatably installed inside the oil collecting chamber, the wheel hub 13 is respectively located in the through groove, a hydraulic oil pump 11 is fixedly installed on the cross beam 5, the output ends on both sides of the hydraulic oil pump 11 are respectively connected and assembled with the wheel hub 13, and the surface of the wheel hub 13 is coated with an oleophilic and hydrophobic layer 14; the wheel hub 13 is a component composed of a hollow tank body and rotating shafts at both ends, and the oleophilic and hydrophobic layer 14 is made of an oleophilic and hydrophobic material (the oleophilic and hydrophobic material refers to a material whose surface is not easily wetted by water but easily wetted by oil), which is used to absorb the recovered oil in the water to achieve the purpose of separation.

[0026] The hydraulic oil pump 11 is an existing component with output ends on both sides. The hydraulic oil pump 11 is connected to an external hydraulic power station through an oil pipe. When working, the hydraulic power station drives the output end of the hydraulic oil pump 11 to rotate clockwise through the oil transported in the oil pipe, thereby causing the wheel hub 13 and the oleophilic and hydrophobic layer 14 to rotate clockwise.

[0027] One end of the elastic component 4 is evenly installed on the side wall of the oil collection chamber, and a scraper 12 is fixedly installed on the other end of the elastic component 4. The scraper 12 is against the surface of the oleophilic and hydrophobic layer 14. The longitudinal beam 3 is provided with a through hole 2 for connecting the oil collection chamber and the oil storage cavity. A recovery component 8 is installed on the lower side of the oil storage cavity; the scrapers 12 are continuously distributed on the right side of the circumferential side of the oleophilic and hydrophobic layer and on the right side of the end of the oleophilic and hydrophobic layer to ensure that the efficiency of the scraping operation is maximized.

[0028] The elastic component 4 enables the scraper 12 to always have a force to press against the surface of the oleophilic and hydrophobic layer 14. When the oleophilic and hydrophobic layer 14 rotates clockwise, the scraper 12 can scrape off the recovered oil adhering to the surface of the oleophilic and hydrophobic layer 14 and guide it to the oil collecting plate 9. The recovered oil flows into the oil storage chamber through the through hole 2 along the inner wall of the oil collecting chamber and the upper flange 15, and is then transported by the recovery component 8 to the oil storage tank on the ship for collection and storage.

[0029] An inclined surface 7 is provided at the bottom of the oil collecting chamber, and the end of the inclined surface 7 close to the longitudinal beam 3 is lower than the end away from the longitudinal beam 3. Such an inclined inclined surface 7 can expose more oleophilic and hydrophobic layers 14 at the bottom of the oil collecting chamber, ensuring that the oleophilic and hydrophobic layers 14 have sufficient contact space with the recovered oil; and the inclination direction of the oil collecting plate 9 is the same as that of the inclined surface 7, so that the recovered oil scraped off by the scraper 12 can converge to the through hole 2 along the inclined oil collecting plate 9.

[0030] The circumferential side of the oleophilic and hydrophobic layer 14 is evenly provided with annular grooves along the axial direction, and annular gear rings 6 are formed between the annular grooves, which can increase the surface area of ​​the oleophilic and hydrophobic layer 14, thereby improving the ability to adsorb and recover oil; the scraper 12 is provided with a toothed edge matching the annular grooves and the annular gear ring 6, thereby ensuring the effect of scraping off the recovered oil.

[0031] Specifically, Figure 4 As shown, the elastic component 4 includes a rectangular rod 43, a spring 42 and a connecting rod 45. The connecting rod 45 is fixedly installed on the upper side of the scraper 12. The guide ring 41 is fixedly installed on the upper side of the connecting rod 45. The inner wall of the oil collecting chamber is fixedly installed with a rectangular rod 43. The guide ring 41 is slidably installed on the rectangular rod 43. The rectangular rod 43 is sleeved with a spring 42 and a gasket 44. The spring 42 is against the guide ring 41 and the gasket 44. The spring 42 enables the guide ring 41 to have a force to move close to the oleophilic and hydrophobic layer 14, so that the scraper 12 is always against the oleophilic and hydrophobic layer 14 through the connecting rod 45. The guide ring 41 and the gasket 44 both have rectangular holes matching the rectangular rod 43, so that the guide ring 41 will not swing circumferentially when moving along the rectangular rod 43, thereby improving the stability of the movement of the scraper 12.

[0032] A limit baffle 46 is fixedly installed at one end of the rectangular rod 43 away from the inner wall of the oil collecting chamber. The limit baffle 46 serves as a safety protection. When installed, it can prevent the guide ring 41 from separating from the rectangular rod 43, and when in use, it can also prevent the scraper 12 from moving excessively.

[0033] In addition, the crossbeam 5 and the frame 1 are both screwed with screws 16, and each gasket 44 is abutted with a pair of screws 16; by adjusting the screwing depth of the screw 16, the gasket 44 can be translated along the rectangular rod 43, thereby adjusting the elastic force of the spring 42 acting on the guide ring 41, so that the force of the scraper 12 against the oleophilic and hydrophobic layer 14 is moderate to match the recovery requirements of recovered oils with different viscosities. The higher the viscosity of the recovered oil, the higher the clamping force required for the scraper 12.

[0034] The setting of the connecting rod 45 enables the guide ring 41, the spring 42, the rectangular rod 43, and the gasket 44 to be located above the scraper 12, and the scraped recovered oil will not adhere to the above-mentioned components, avoiding the viscosity of the recovered oil affecting the movement between them.

[0035] Specifically, the recovery component 8 includes a V-shaped bottom plate 81, a collecting tank 82 and an oil recovery pump 83. The V-shaped bottom plate 81 is fixedly installed at the bottom of the oil storage chamber, and the collecting tank 82 is connected to the center of the lower side of the V-shaped bottom plate 81. The oil recovery pump 83 is fixedly installed at the front end of the collecting tank 82, and the delivery pipe 84 is fixedly installed at the output end of the oil recovery pump 83; the oil recovery pump 83 is connected to the external hydraulic power station through the oil pipe, and the left and right ends of the V-shaped bottom plate 81 are high and the middle is low, which is conducive to the recovery oil to converge into the collection tank 82. When the oil recovery pump 83 is working, the recovered oil in the collection tank 82 can be sent to the external oil storage tank through the delivery pipe 84 for collection and storage.

[0036] Since the weight of the delivery pipe 84 will increase during transportation, a buoy may be installed on the delivery pipe 84 to prevent the delivery pipe 84 from sinking.

[0037] A pair of lifting rings 10 are fixedly installed on the top of the cross beam 5. When in use, steel cables are connected between the lifting rings 10 and the hull, so that the oil skimmer can be towed by the ship to a designated area.

[0038] Working principle:

[0039] The hydraulic oil pump 11 and the oil recovery pump 83 are both driven by hydraulic oil, which can provide power while avoiding the generation of electric arcs, thereby improving safety in use.

[0040] The hydraulic power station can be installed on board or on shore according to the needs of different working conditions. The working principle is now explained based on the working conditions applied on board.

[0041] When in use, the hull is connected to the lifting ring 10 through a steel cable, a hydraulic power station and an oil storage tank are arranged on the ship, the hydraulic oil pump 11 is connected to the hydraulic power station through an oil pipe, and the oil storage tank is connected to the recovery component 8.

[0042] When working, the oil skimmer floats on the water as a whole, and the hydraulic power station drives the output shafts on both sides of the hydraulic oil pump 11 to rotate, rotating the hub 13 and the oleophilic and hydrophobic layer 14 clockwise. At the same time, the elastic component 4 makes the scraper 12 always rest on the oleophilic and hydrophobic layer 14. When the recovered oil is adsorbed on the oleophilic and hydrophobic layer 14 and rotates to the scraper 12, it will be scraped off and enter the oil storage chamber along the oil collecting plate 9 and the through hole 2. The collected recovered oil will be transported to the oil storage tank on the ship through the recovery component 8 for collection and storage. The recovered oil can also be reused to collect various floating oils, such as crude oil, gasoline, diesel, etc.

[0043] In addition, the elastic component 4 can ensure that the scraper 12 always has a force to press against the surface of the oleophilic and hydrophobic layer 14, and the pressing force on the scraper 12 can also be adjusted according to the loss situation and the viscosity of the recovered oil to ensure the scraping effect.

[0044] The working parameters are as follows: oil recovery speed of the oil recovery machine, 40m³ / h; oil recovery efficiency, 96%; working temperature, 0℃-70℃; wheel speed, 40r / min~100r / min.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
