Description

Technical Field

[0001] This utility model belongs to the field of adsorbent recovery technology, specifically relating to a magnetic clay adsorbent addition and recovery device for addressing marine oil pollution. Background Technology

[0002] In marine oil pollution treatment, magnetic clay adsorbents are widely used due to their high efficiency in adsorbing oil and their ability to magnetically separate it. However, existing technologies have the following drawbacks: the recovery of adsorbents and oil relies on manual dredging, which is inefficient (less than 500 kg recovered per hour); the separation of magnetic adsorbents and oil is incomplete during the separation process, resulting in low adsorbent reuse rates; the equipment lacks marine environmental adaptability design, has insufficient corrosion resistance and floating stability, and is prone to equipment failure due to seawater corrosion during adsorbent transportation. Therefore, there is an urgent need for a specialized device that can efficiently recover magnetic clay adsorbents through extraction and achieve cyclic addition after separation. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, this utility model provides a magnetic clay adsorbent addition and recovery device for combating marine oil pollution, thereby solving the problems mentioned in the background technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A magnetic clay adsorbent addition and recovery device for combating marine oil pollution includes a separation tank. The separation tank has an inlet pipe on its upper side and an overflow pipe on one side. A stirring motor is located on one side of the inlet pipe, with its output shaft connected to a stirring shaft. Stirring blades are mounted on the stirring shaft. A discharge pipe is located on the lower side of the separation tank, with a valve on it. A spiral conveying assembly is located below the discharge pipe. Multiple fixing blocks are located on the outside of the separation tank, with an electromagnetic chuck on one side of each fixing block. The overflow pipe passes through the electromagnetic chuck. A vacuum pump is located on the inlet pipe, and a recovery device is located on one side of the vacuum pump. The recovery device includes a connecting plate with multiple floats. A debris screen is located at the center of the connecting plate, with a water intake port inside the debris screen. An oil discharge pipe is located below the water intake port.

[0005] Furthermore, the screw conveyor assembly includes a housing, a discharge port on one side of the housing, a conveying shaft inside the housing, a screw blade on the conveying shaft, and the conveying shaft is connected to the output end of the conveying motor; a feed port is provided on the upper side of the housing, and the feed port is connected to the discharge pipe.

[0006] Furthermore, the oil drain pipe is connected to the vacuum pump, and the electromagnetic chuck is conical in shape and compatible with the separation tank.

[0007] Furthermore, the discharge port is connected to an adsorbent projection device, the spiral blades are made of stainless steel and coated with an antistatic coating, and the casing is coated with an anti-corrosion coating.

[0008] Furthermore, the fixing block is fixedly connected to the separation tank, and the electromagnetic chuck is fixedly connected to the fixing block.

[0009] Furthermore, the top of the debris-blocking net is equipped with a filter screen, the connecting plate is triangular, the floats are evenly distributed at the top corners of the triangular connecting plate, and all metal parts are coated with an anti-corrosion coating.

[0010] Compared with the prior art, this utility model has the following advantages: The recovery device floats on the surface of the oily wastewater via a buoy, the triangular connecting plate is adapted to the wave environment at sea, the trash can and filter can intercept large impurities, and the vacuum pump extracts the oily magnetic clay adsorbent through the suction port, solving the problem of low efficiency of manual salvage. The separator uses centrifugal force to achieve initial separation. The conical electromagnetic chuck is attached to the outside of the separator. When energized, it generates a gradient magnetic field, which causes the magnetic clay adsorbent to accumulate on the inner wall of the separator. The overflow pipe can discharge the upper layer of oil after separation, thus improving the separation efficiency. After separation, the magnetic clay adsorbent enters the screw conveyor assembly through the discharge pipe. The stainless steel screw blades, combined with the anti-corrosion housing, are adapted to the high-salt marine environment. The adsorbent is then transported to the projection device through the discharge port for recycling, reducing adsorbent consumption. All metal parts are coated with an anti-corrosion coating to improve their resistance to seawater corrosion. Attached Figure Description

[0012] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example

[0013] like Figure 1-4 As shown, this utility model discloses a magnetic clay adsorbent addition and recovery device for addressing marine oil pollution. It includes a separation tank 1, an inlet pipe 101 on the upper side of the separation tank 1, an overflow pipe 102 on one side of the separation tank 1, a stirring motor 3 on one side of the inlet pipe 101, an output shaft of the stirring motor 3 connected to a stirring shaft 5, stirring blades 6 on the stirring shaft 5, a discharge pipe 7 on the lower side of the separation tank 1, a valve 8 on the discharge pipe 7, a spiral conveying assembly on the lower side of the discharge pipe 7, multiple fixing blocks 14 on the outer side of the separation tank 1, an electromagnetic chuck 2 on one side of the fixing block 14, the overflow pipe 102 passing through the electromagnetic chuck 2, a vacuum pump 15 on the inlet pipe 101, a recovery device 4 on one side of the vacuum pump 15, a connecting plate 44, multiple floats 41 on the connecting plate 44, a debris screen 42 at the center of the connecting plate 44, a water intake 43 inside the debris screen 42, and an oil discharge pipe 45 below the water intake 43.

[0014] The screw conveyor assembly includes a housing 9, with a discharge port 13 on one side. Inside the housing 9 is a conveying shaft 10, on which spiral blades 11 are mounted. The conveying shaft 10 is connected to the output end of a conveying motor 12. An inlet is located on the upper side of the housing 9, connected to a discharge pipe 7. Specifically, the separated magnetic clay adsorbent enters the screw conveyor assembly through the discharge pipe and is then conveyed to the projection device through the discharge port for recycling.

[0015] The oil drain pipe 45 is connected to the vacuum pump 15. The electromagnetic chuck 2 is conical and is compatible with the separation tank 1. Specifically, the conical electromagnetic chuck generates a gradient magnetic field to enhance the aggregation and separation of the magnetic adsorbent, and the overflow pipe discharges the upper layer of oil.

[0016] The discharge port 13 is connected to the adsorbent projection device. The spiral blades 11 are made of stainless steel with an anti-static coating, and the casing 9 is coated with an anti-corrosion coating. Specifically, the stainless steel spiral blades and the anti-corrosion casing are adapted to the high-salt marine environment, and the magnetic adsorbent is transported to the projection device through the discharge port for recycling.

[0017] The fixing block 14 is fixedly connected to the separation tank 1, and the electromagnetic chuck 2 is fixedly connected to the fixing block 14. The top of the debris screen 42 is equipped with a filter screen, the connecting plate 44 is triangular, the floats 41 are evenly distributed at the apex of the triangular connecting plate 44, and all metal parts are coated with an anti-corrosion coating.

[0018] Specifically, the metal parts are coated with an anti-corrosion coating to improve their resistance to seawater corrosion. The recovery device floats on the surface of the oily wastewater via a buoy. The triangular connecting plate is adapted to the wave environment at sea, and the debris screen can intercept large impurities.

[0019] Operating principle: The float 41 of the recovery device 4 makes the connecting plate 44 float on the oily sea surface. The debris screen 42 and filter screen intercept plastic, floating garbage and other debris. The vacuum pump 15 draws the oil mixture containing magnetic clay adsorbent through the suction port 43 and delivers it to the feed pipe 101 through the oil discharge pipe 45. The mixture enters the separator 1, where the stirring motor 3 drives the stirring blades 6 to agitate the liquid. Combined with centrifugal force, this initially separates the magnetic adsorbent from the oil. The electromagnetic chuck 2, when energized, generates a magnetic field, causing the adsorbent to accumulate on the tank wall under the influence of the magnetic force. The upper layer of oil is discharged and recovered through the overflow pipe 102. Valve 8 is opened, and the separated magnetic adsorbent enters the screw conveyor assembly through the discharge pipe 7. The conveyor motor 12 drives the screw blades 11 to transport the adsorbent from the discharge port 13 to the adsorbent dosing device, completing the cyclic dosing. The surface of the debris screen and electromagnetic chuck should be cleaned regularly, and the integrity of the anti-corrosion coating on the casing should be checked to ensure stable operation of the equipment in a marine environment.
