Description

Technical Field

[0001] This utility model relates to the field of seawater treatment technology, specifically to a superhydrophobic magnetic sponge adsorption device. Background Technology

[0002] In the field of marine pollution control, seawater purification has always been a key research focus and a major challenge. Traditional seawater purification methods, such as physical filtration and chemical precipitation, have limitations in treating oil pollution. Physical filtration is insufficient to remove tiny oil droplets, while chemical precipitation may introduce secondary pollution. With the increasing frequency of offshore oil extraction and maritime transport activities, oil pollution in seawater is becoming increasingly serious, posing a significant threat to the marine ecological environment.

[0003] However, commonly used adsorption materials, such as activated carbon, although they have a certain adsorption capacity, do not have a good selective adsorption effect on oil pollution and are difficult to recover, which affects the overall use effect of adsorption devices and the treatment effect on seawater oil pollution. Utility Model Content

[0004] The purpose of this invention is to provide a superhydrophobic magnetic sponge adsorption device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a superhydrophobic magnetic sponge adsorption device, comprising a float and a lifting base, wherein a connecting frame is detachably connected to the bottom end of the float, a through groove is provided at the center of the lower surface of the connecting frame, a filling sponge is provided inside the connecting frame, a collecting cylinder is fixedly connected to the lower surface of the connecting frame, a base is fixedly connected to the bottom end of the collecting cylinder, a counterweight is fixedly connected to the center of the lower surface of the base, and a connecting mechanism is also included, wherein the connecting mechanism is used for connecting and lifting between the float and the lifting base.

[0006] Preferably, the float and the connecting frame are connected by bolts and threaded grooves. The connecting frame is made of PVC material. The top of the lifting seat is connected to external lifting equipment. The lifting equipment can use the lifting seat to detach the float from the seawater.

[0007] Preferably, the filling sponge is a superhydrophobic magnetic sponge, which is a composite of magnetic nanoparticles and superhydrophobic materials, coated onto the surface of a polyurethane sponge by an impregnation method, and the filling sponge is inserted in the middle of the floating plate and the connecting frame.

[0008] Preferably, the collecting cylinder is made of polyester fiber woven mesh, with a silica composite coating inside and a polyvinyl alcohol coating on the outside to form a hydrophilic surface. The single filament diameter is 5-15 micrometers, and a mesh structure with a pore size of 10-50 micrometers is formed by precision weaving, while also adopting a corrugated folding design.

[0009] Preferably, the connecting mechanism includes an annular groove on the upper surface of the float plate, a positioning groove evenly spaced around the inner wall of the annular groove, a magnetic ring fixed to the inner side of the positioning groove, an annular insert block that engages with the annular groove fixed to the lower surface of the lifting base, a movable groove at the bottom of the annular insert block, a rotating shaft rotatably connected to the top of the movable groove, a first magnetic block fixed to the inner side of the movable groove, a second magnetic block slidably connected to the outer side of the movable groove, a magnetic rod fixed to the outer side of the second magnetic block, the outer side of the magnetic rod engaging with the positioning groove, and a pull ring at the top of the lifting base, the lower surface of the pull ring being fixed to the inner side of the second magnetic block.

[0010] Preferably, the positions and numbers of the movable groove and the positioning groove correspond, the magnetic force of the magnetic ring is greater than the magnetic force of the first magnetic block, and the contact surfaces of the first magnetic block and the second magnetic block are magnetically attracted to each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This superhydrophobic magnetic sponge adsorption device, by setting a float plate, allows the entire adsorption device to float on the water surface. At the same time, a counterweight is set at the bottom of the adsorption device to ensure vertical suspension. At this time, the surface of the filling sponge in the connecting frame repels water molecules, allowing only oil molecules to penetrate into the sponge pores through capillary action. Simultaneously, the filling sponge captures oil stains through van der Waals forces and physical adsorption. After the oil droplets aggregate inside the sponge, they can enter the interior of the collection cylinder through the through groove at the bottom of the connecting frame for centralized collection. Furthermore, the collection cylinder can discharge seawater contained in the oil and prevent external seawater from entering the interior of the collection cylinder, effectively improving the overall performance of the adsorption device and the efficiency of oil stain treatment.

[0013] 2. This superhydrophobic magnetic sponge adsorption device features an annular groove at the top of a float. When the annular insert at the bottom of the lifting seat is inserted into the annular groove on the float, the magnetic rod inside the insert, due to the magnetic force of the magnetic ring within the annular groove, can be inserted into the positioning slot. This allows for rapid docking between the lifting seat and the adsorption device. External lifting equipment can then quickly lift the adsorption device out of the seawater. Simultaneously, by pulling the pull ring at the top of the lifting seat, the pull ring can drive the magnetic rod out of the positioning slot in the annular groove via a second magnetic block. This allows for rapid disassembly of the float and the lifting seat, improving the ease of recycling the adsorption device. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides two technical solutions:

[0021] Example 1: A superhydrophobic magnetic sponge adsorption device includes a float 1 and a lifting base 2. The bottom end of the float 1 is detachably connected to a connecting frame 4.

A collection cylinder 6 is fixedly connected to the lower surface of the connecting frame 4. A base plate 601 is fixedly connected to the bottom end of the collection cylinder 6. A counterweight 7 is fixedly connected to the center of the lower surface of the base plate 601. The device also includes a connecting mechanism 3, which is used for connecting and lifting the float 1 and the lifting base 2.

The lifting equipment can use the lifting seat 2 to lift the float 1 out of the seawater. By separating the float 1 from the connecting frame 4, the internal filling sponge 5 can be replaced quickly.

[0023] The filling sponge 5 is made of superhydrophobic magnetic sponge, which combines magnetic nanoparticles with superhydrophobic materials and coats the surface of polyurethane sponge by impregnation. The filling sponge 5 is inserted in the middle of the float 1 and the connecting frame 4. The filling sponge 5 can effectively block seawater and absorb oil, while simultaneously channeling the oil into the collection cylinder 6 through the channel 401.

[0024] The collection cylinder 6 is made of polyester fiber woven mesh. The inside of the collection cylinder 6 is coated with a silica composite coating, and the outside of the collection cylinder 6 is coated with polyvinyl alcohol to form a hydrophilic surface. The single filament diameter is 5-15 micrometers. Through precision weaving, a mesh structure with a pore size of 10-50 micrometers is formed. At the same time, a corrugated folding design is adopted. The inside of the collection cylinder 6 allows the internal seawater to be discharged outward under pressure, but prevents oil from passing through. The outside uses the surface tension of water molecules to form a continuous water film to prevent external seawater from seeping in backward. The corrugated folding design also makes it easy to fold and store the entire adsorption device.

[0025] Example 2 differs from Example 1 mainly in that:

[0026] A superhydrophobic magnetic sponge adsorption device includes a float 1 and a lifting base 2. The bottom end of the float 1 is detachably connected to a connecting frame 4. A through groove 401 is opened at the center of the lower surface of the connecting frame 4. The interior of the connecting frame 4 is filled with a sponge 5. A collection cylinder 6 is fixedly connected to the lower surface of the connecting frame 4. A base plate 601 is fixedly connected to the bottom end of the collection cylinder 6. A counterweight 7 is fixedly connected to the center of the lower surface of the base plate 601. The device also includes a connecting mechanism 3, which is used for connecting and lifting the float 1 and the lifting base 2.

[0027] The float 1 and the connecting frame 4 are connected by bolts and screws. The connecting frame 4 is made of PVC material. The top of the lifting seat 2 is connected to the external lifting equipment. The lifting equipment can use the lifting seat 2 to lift the float 1 out of the seawater.

[0028] The filling sponge 5 is made of superhydrophobic magnetic sponge, which combines magnetic nanoparticles with superhydrophobic materials and coats them onto the surface of polyurethane sponge by impregnation. The filling sponge 5 is inserted in the middle of the floating plate 1 and the connecting frame 4.

[0029] The collecting cylinder 6 is made of polyester fiber woven mesh. The inside of the collecting cylinder 6 is coated with a silica composite coating, and the outside of the collecting cylinder 6 is coated with polyvinyl alcohol to form a hydrophilic surface. The single filament diameter is 5-15 micrometers. It is precisely woven to form a mesh structure with a pore size of 10-50 micrometers, and a corrugated folding design is adopted.

[0030] The connecting mechanism 3 includes an annular groove 101 on the upper surface of the float 1. Positioning grooves 102 are evenly spaced and circumferentially formed on the inner wall of the annular groove 101. A magnetic ring 103 is fixedly connected to the inner side of the positioning groove 102. An annular insert 201, which engages with the annular groove 101, is fixedly connected to the lower surface of the lifting base 2. A movable groove 301 is formed at the bottom inside the annular insert 201. A rotating shaft 302 is rotatably connected to the top of the inner side of the movable groove 301. A first magnetic block 303 is fixedly connected to the inner side of the movable groove 301. A second magnetic block 304 is slidably connected to the outer side of the movable groove 301.

The top of the lifting seat 2 is provided with a pull ring 306. The lower surface of the pull ring 306 is fixed to the inner side of the second magnetic block 304. Under normal conditions, the second magnetic block 304 can drive the magnetic rod 305 into the interior of the annular insert 201 due to the magnetic force of the first magnetic block 303. When the annular insert 201 is inserted into the annular groove 101 on the float 1, the magnetic rod 305 can be driven into the positioning groove 102 on the annular groove 101 due to the magnetic force of the magnetic ring 103 in the positioning groove 102, thus completing the rapid docking of the float 1 and the lifting seat 2.

[0031] The positions and numbers of the movable groove 301 and the positioning groove 102 correspond. The magnetic force of the magnetic ring 103 is greater than that of the first magnetic block 303. The contact surfaces of the first magnetic block 303 and the second magnetic block 304 are magnetically attracted. Meanwhile, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] In this embodiment, the adsorption device is placed in the seawater where oil pollution needs to be treated. The weight of the counterweight 7 pulls the collection cylinder 6 to unfold, causing the adsorption device to float vertically on the water surface. Due to the adsorption effect of the sponge 5 filled in the float plate 1 and the connecting frame 4, the seawater is effectively blocked, and the oil pollution is collected and treated by entering the collection cylinder 6 through the channel 401. When the annular insert 201 at the bottom of the lifting seat 2 is inserted into the annular groove 101 on the float plate 1, the magnetic rod 305 in the annular insert 201 can be inserted into the positioning groove 102 on the annular groove 101 due to the magnetic force of the magnetic ring 103. At this time, the external lifting equipment can use the lifting seat 2 to quickly detach the adsorption device from the seawater and recover the entire adsorption device.
