[0002] With the continuous advancement of industrialization, a large amount of sludge or wastewater containing magnetic particles generated by sewage treatment, mineral processing, metallurgy and other industries requires effective separation and recovery technology.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] In the description of this application, it should be understood that the words "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] See also Figures 1 to 4 , the embodiment of the present application provides a nano-magnetic powder recovery and reuse device, including: a first box body 1, a magnetic roller 2, a second box body 3, a mud driving assembly 4, a transmission assembly 5 and a mud spraying assembly 6. Among them, the first box body 1 is provided with a accommodating chamber 11. The magnetic roller 2 is rotatably arranged in the accommodating chamber 11, and is used to adsorb the magnetic powder in the sludge entering the accommodating chamber 11. The second box body 3 is arranged on one side of the first box body 1 and is provided with a mounting chamber 31. The mud driving assembly 4 is slidably arranged in the mounting chamber 31, and is used to hold the sludge and can slide in the mounting chamber 31 in the vertical direction. The transmission assembly 5 is arranged in the mounting chamber 31 and is connected to the driving end of the mud driving assembly 4, and the end of the transmission assembly 5 away from the mud driving assembly 4 is connected to the rotating shaft extending from the magnetic roller 2 to the mounting chamber 31, so as to convert the linear motion of the mud driving assembly 4 into a rotational motion and transmit it to the magnetic roller 2, driving the magnetic roller 2 to rotate. The input end of the mud spraying assembly 6 is connected to the mud holding driving assembly 4 , and the output end extends into the accommodating cavity 11 and is aligned with the surface of the magnetic roller 2 to spray the sludge in the mud holding driving assembly 4 onto the surface of the magnetic roller 2 .

[0035] It should be noted that a sewage outlet connected to the accommodating chamber 11 is provided at the bottom of the first housing 1, so that after the sludge falls into the accommodating chamber 11 under the action of gravity, it can be discharged from the accommodating chamber 11 through the sewage outlet. Furthermore, the bottom of the first housing 1 is in a funnel shape that is wide at the top and narrow at the bottom to accelerate the discharge of sludge from the accommodating chamber 11.

[0036] The technical solution provided by the present application utilizes the weight of the sludge contained in the mud driving component 4 and its own weight, so that the mud driving component 4 can convert the gravitational potential energy into kinetic energy, and then convert the kinetic energy into energy to drive the magnetic roller 2 to rotate through the transmission component 5, so as to complete the rotation of the magnetic roller 2, so that the magnetic roller 2 can adsorb as much nano magnetic powder as possible. In this way, there is no need to set up an additional power device specifically for driving the magnetic roller 2 to rotate, which effectively reduces the manufacturing and use costs of the device. In detail, first, a accommodating chamber 11 is opened in the first box body 1, and the magnetic roller 2 is arranged in the accommodating chamber 11, and the magnetic roller 2 uses its own magnetism to adsorb the magnetic powder. The mud driving component 4 is slidably arranged in the installation chamber 31 of the second box body 3, and the sludge can be contained and slid in the vertical direction, and the gravitational potential energy of the mud driving component 4 can be converted into kinetic energy. When working, its sliding process can be used as a power source, and the linear motion is converted into the rotational motion of the magnetic roller 2 through the transmission component 5. In this way, there is no need to set up an additional power device specifically for driving the magnetic roller 2 to rotate, which effectively reduces the manufacturing and use costs of the device. At the same time, the mud spraying component 6 sprays the sludge in the mud driving component 4 onto the surface of the magnetic roller 2, thereby improving the efficiency and effect of magnetic powder adsorption, making the magnetic powder recovery process more stable and efficient, and reducing resource waste. Moreover, since the weight of the sludge is much greater than that of the nano magnetic powder, the sludge can automatically separate from the magnetic roller 2 under its own gravity, thereby completing the preliminary separation of the sludge and the nano magnetic powder.

[0037] In some embodiments, see Figure 2 and Figure 3 The mud driving assembly 4 includes a mud bucket 41 and a rack 42. The mud bucket 41 is arranged in the installation cavity 31 and can slide in the vertical direction along the inner wall of the installation cavity 31. The rack 42 is arranged on one side of the mud bucket 41, and the rack 42 extends in the vertical direction. The rack 42 is connected to the transmission assembly 5 to convert the linear motion of the mud bucket 41 into rotational motion, thereby driving the magnetic roller 2 to rotate.

[0038] The mud bucket 41 in the mud driving assembly 4 is made of high-strength and corrosion-resistant plastic material, and its shape is designed to be an inverted trapezoid that is wide at the top and narrow at the bottom. A mud outlet is provided on one side of the mud bucket 41, and is connected to the mud suction pipe 61. On one side of the mud bucket 41, a rack 42 is firmly installed by welding or bolting. The rack 42 is made of alloy steel that has been quenched and tempered, and has good strength and wear resistance. Its tooth shape is processed with high precision to ensure stable connection with the transmission assembly 5. When the mud bucket 41 slides in the vertical direction in the installation cavity 31, since the rack 42 is fixedly connected to the mud bucket 41, the rack 42 will move synchronously therewith, and transmit the movement to the transmission assembly 5, so that the linear movement of the mud bucket 41 is converted into rotational movement, driving the magnetic roller 2 to rotate. This embodiment realizes the rotation of the magnetic roller 2 by utilizing the movement of the mud bucket 41, avoids setting a separate power source for the magnetic roller 2, and reduces the complexity and cost of the device.

[0039] Furthermore, the mud driving assembly 4 further includes a slide rail 43, which is vertically arranged on the inner wall of the mounting cavity 31, and the mud bucket 41 is slidably connected to the slide rail 43. The slide rail 43 is used to limit the movement path of the mud bucket 41, so that the movement of the mud bucket 41 is more stable, and the mud in the mud bucket 41 is prevented from spilling out due to the unstable movement of the mud bucket 41.

[0040] In some embodiments, see Figure 2 and Figure 3 , the mud driving assembly 4 also includes an elastic member 44. The elastic member 44 can be an elastic pad, a spring, etc. The elastic member 44 is arranged at the bottom of the installation cavity 31, and the mud bucket 41 can slide to the elastic member 44 and deform the elastic member 44. When the mud bucket 41 is filled with sludge, due to the gravity of the mud bucket 41 itself and the gravity of the sludge, the mud bucket 41 automatically slides downward along the slide rail 43, converting the gravitational potential energy into kinetic energy. During the downward sliding process of the mud bucket 41, the rack 42 moves downward synchronously with the mud bucket 41, and the transmission assembly 5 is used to convert the movement of the rack 42 into rotation, thereby driving the magnetic roller 2 to rotate. The sludge in the mud bucket 41 is continuously input and continuously output through the mud spraying assembly 6, ensuring that when the magnetic roller 2 rotates, there is continuous output of sludge to the magnetic roller 2. The rotation of the magnetic roller 2 can not only lay the sludge more evenly, but also use the centripetal force of the rotation of the magnetic roller 2 to accelerate the falling of the sludge, so that the sludge is separated from the nano magnetic powder. When the mud bucket 41 slides down to the elastic member 44, pressure is formed on the elastic member 44, thereby compressing the elastic member 44. As the sludge in the mud bucket 41 becomes less and less, the overall mass of the mud bucket 41 decreases until the total gravity of the mud bucket 41 and the sludge is less than the elastic force of the elastic member 44. The mud bucket 41 will be bounced up by the elastic force of the elastic member 44, so that the mud bucket 41 overcomes the gravity and slides upward. It should be noted that after the mud bucket 41 contacts the elastic member 44, the sludge input into the mud bucket 41 is stopped until the mud bucket 41 is bounced up to the highest point by the elastic member 44, the mud bucket 41 is stabilized, and then the sludge is continued to be input, and the previous process of the mud bucket 41 descending is repeated. In the process of the mud bucket 41 bouncing upward, the rack 42 will also move upward, driving the magnetic roller 2 to rotate in the opposite direction through the transmission assembly 5, so that the magnetic roller 2 adsorbs the nano magnetic powder more evenly, and it is also conducive to the subsequent separation of the nano magnetic powder from the magnetic roller 2.

[0041] In some embodiments, the transmission assembly 5 includes at least two stages of transmission gears, both of which are arranged in the second housing 3, wherein the first stage transmission gear 51 is meshed between the other stage transmission gear 51 and the rack 42, and the other stage transmission gear 51 is fixedly sleeved on the rotating shaft of the magnetic roller 2. The rack 42 is meshed with the first stage transmission gear 51, converting the linear motion of the rack 42 into the rotational motion of the gear, and the second stage transmission gear 52 rotates synchronously by meshing with the first stage rotating gear, and then drives the rotating shaft of the magnetic roller 2 to rotate, and then the magnetic roller 2 is rotated.

[0042] In some embodiments, see Figure 2 and Figure 4 The transmission assembly 5 includes a primary transmission gear 51, a secondary transmission gear 52 and a tertiary transmission gear 53. The primary transmission gear 51 is meshed with the rack 42, and the second transmission gear 52 is meshed with the primary transmission gear 51 and the tertiary transmission gear 53 respectively. The tertiary transmission gear 53 is fixedly sleeved on the rotating shaft of the magnetic roller 2. Among them, the radius of the primary transmission gear 51 is greater than the radius of the secondary transmission gear 52, and the radius of the secondary transmission gear 52 is greater than the radius of the tertiary transmission gear 53. The linear motion of the rack 42 is converted into a rotational motion and transmitted to the magnetic roller 2 by the primary transmission gear 51, the secondary transmission gear 52 and the tertiary transmission gear 53, so that the magnetic roller 2 can be rotated without additional power equipment. By making the radius of the primary transmission gear 51 greater than the radius of the secondary transmission gear 52, and the radius of the secondary transmission gear 52 greater than the radius of the tertiary transmission gear 53, the rotation of the magnetic roller 2 can be increased by multi-stage gears with different radii, thereby increasing the centripetal force of the rotation of the magnetic roller 2, which is beneficial to the separation of sludge and nano magnetic powder, and improving the distribution uniformity of nano magnetic powder.

[0043] In some embodiments, the mud spraying assembly 6 includes a mud suction pipe 61, a hydraulic pump 62, and a plurality of mud discharge nozzles 63. One end of the mud suction pipe 61 is connected to the mud bucket 41, and the other end extends into the accommodating chamber 11 and is connected to a plurality of mud discharge nozzles 63. The plurality of mud discharge nozzles 63 are all aligned with the side surface of the magnetic roller 2 and are arranged at intervals along the axial direction of the magnetic roller 2. The hydraulic pump 62 is arranged on the mud suction pipe 61. By using the hydraulic pump 62 to provide power, the sludge in the mud bucket 41 is sucked into the mud suction pipe 61 and sprayed through the mud discharge nozzle 63. The mud discharge nozzle 63 is aligned with the side surface of the magnetic roller 2 to ensure that the sludge can be sprayed onto the surface of the magnetic roller 2 as much as possible, and the sludge is prevented from falling directly to the bottom of the accommodating chamber 11. The plurality of mud discharge nozzles 63 are arranged at intervals along the axial direction of the magnetic roller 2, and combined with the rotation of the magnetic roller 2, it is beneficial to improve the uniformity of the sludge distribution on the surface of the magnetic roller 2, and avoid waste of the surface area of ​​the magnetic roller 2, such as avoiding the situation where most of the sludge is accumulated on a part of the surface of the magnetic roller 2, and there is almost no sludge on the other part of the surface.

[0044] In some embodiments, the nano magnetic powder recycling and reuse device further includes a spray assembly 7, which is fixed in the accommodating chamber 11 and extends outside the accommodating chamber 11. The spray assembly 7 includes a support 71, a water inlet pipe 72, and a plurality of spray nozzles 73. The support 71 is fixed to the inner wall of the accommodating chamber 11, the water inlet pipe 72 is arranged on the support 71 and can be connected to an external water source device, and the plurality of spray nozzles 73 are all connected to the water inlet pipe 72, and the plurality of spray nozzles 73 are arranged at intervals along the axial direction of the magnetic roller 2, and the water outlets of the spray nozzles 73 are aligned with the side surface of the magnetic roller 2. By using the spray assembly 7 to rinse the surface of the magnetic roller 2, the sludge on the surface of the magnetic roller 2 is further cleaned, so as to prevent part of the sludge from sticking to the surface of the magnetic roller 2 and being unable to fall off, thereby affecting the subsequent attachment of the sludge and the adsorption of the nano magnetic powder. In detail, the support member 71 is arranged in the accommodating cavity 11, and the water inlet pipe 72 is connected to the support member 71 so that the water inlet pipe 72 can be supported by the support member 71. The external water source equipment inputs water into the water inlet pipe 72, and the water inlet pipe 72 then sprays the water onto the magnetic roller 2 through the spray nozzle 73 to complete the cleaning of the surface of the magnetic roller 2. It should be noted that the multiple spray nozzles 73 are arranged at intervals along the axial direction of the magnetic roller 2, and cooperate with the rotation of the magnetic roller 2 itself, which is conducive to expanding the area of ​​the magnetic roller 2 that can be covered by the spray nozzle 73 and improving the cleaning range. In addition, the water flow is diverted to multiple spray nozzles 73 for injection, which is conducive to reducing the water pressure and avoiding excessive water pressure, which will wash away the nano magnetic powder attached to the magnetic roller 2 and cause unnecessary waste.

[0045] In some embodiments, see Figure 2 The nano-magnetic powder recycling and reuse device also includes a magnetic powder scraping component 8, which is arranged on one side of the first box body 1 and connected to the accommodating chamber 11. The magnetic scraping end of the magnetic powder scraping component 8 extends into the accommodating chamber 11 and contacts the side surface of the magnetic roller 2 to scrape the magnetic powder on the magnetic roller 2. When the magnetic roller 2 rotates to adsorb the nano-magnetic powder, the surface of the magnetic roller 2 will contact the magnetic powder scraping component 8, so that the nano-magnetic powder adsorbed on the magnetic roller 2 is scraped and collected, so that the adsorption and scraping collection of the nano-magnetic powder are almost carried out simultaneously, which is conducive to improving the efficiency of nano-magnetic powder recovery, and compared with the traditional nano-magnetic powder collection, the device for adsorbing the nano-magnetic powder needs to be disassembled and then collected, which is more convenient and quick. In addition, because the adsorption and scraping collection of the nano-magnetic powder are almost carried out simultaneously, the magnetic roller 2 can be used continuously, and the subsequent adsorption effect of the nano-magnetic powder will not be greatly affected by excessive nano-magnetic powder attached to the surface of the magnetic roller 2.

[0046] Furthermore, the magnetic powder scraping assembly 8 includes a magnetic powder recovery container 81, a magnetic powder channel 82, and a magnetic scraping plate 83. The magnetic powder recovery container 81 is arranged outside the first housing 1. The two ends of the magnetic powder channel 82 are respectively connected to the magnetic powder recovery container 81 and the accommodating chamber 11. The magnetic scraping plate 83 is arranged in the accommodating chamber 11 and is located at the caliber of the magnetic powder channel 82, so that the magnetic powder scraped from the magnetic roller 2 by the magnetic scraping plate 83 can enter the magnetic powder channel 82. The magnetic scraping plate 83 is in contact with the magnetic roller 2. While the magnetic roller 2 rotates to absorb the nano-magnetic powder, the magnetic scraping plate 83 also synchronously scrapes the adsorbed nano-magnetic powder from the magnetic roller 2. The scraped nano-magnetic powder will enter the magnetic powder recovery container 81 along the magnetic powder channel 82 to complete the recovery of the nano-magnetic powder.

[0047] For further information, see Figure 2 , the magnetic powder scraping assembly 8 also includes a receiving plate 84, which is arranged in the accommodating chamber 11 and located at the caliber of the magnetic powder channel 82, and the receiving plate 84 is located below the magnetic scraping plate 83. The receiving plate 84 is mainly provided to cooperate with the situation of the magnetic roller 2 reversing as described in the above-mentioned embodiment. In detail, when the mud bucket 41 moves from top to bottom, it drives the rack 42 to move from top to bottom, and the multi-stage transmission gear meshing with the rack 42 rotates, and the transmission gear then drives the magnetic roller 2 to rotate. At this time, the rotation of the magnetic roller 2 is a positive transmission. Taking the figure as an example, assuming that the positive rotation is a clockwise rotation, the nano-magnetic powder scraped from the magnetic roller 2 by the magnetic scraping plate 83 will fall to the upper surface of the magnetic scraping plate 83, and then fall into the magnetic powder recovery container 81 along the magnetic powder channel 82. When the mud bucket 41 moves from bottom to top, the rack 42 will also move from bottom to top. At this time, the rotation of the magnetic roller 2 driven by the transmission gear is reverse rotation, that is, counterclockwise rotation. The nano magnetic powder scraped off the magnetic roller 2 by the magnetic scraping plate 83 will directly fall down to the bottom of the accommodating chamber 11, resulting in a waste of nano magnetic powder. However, in this embodiment, a receiving plate 84 is provided below the magnetic scraping plate 83, and the receiving plate 84 is located at the caliber of the magnetic powder channel 82, so that the nano magnetic powder scraped off the magnetic roller 2 by the magnetic scraping plate 83 will be received by the receiving plate 84, and then fall into the magnetic powder recovery container 81 through the magnetic powder channel 82.

[0048] It should be noted that the magnetic powder channel 82, the magnetic scraper plate 83 and the receiving plate 84 are all arranged at an angle so that the nano-magnetic powder can fall into the magnetic powder recovery container 81 along the magnetic powder channel 82 under the action of gravity, thereby avoiding the accumulation of nano-magnetic powder on the surface of the magnetic scraper plate 83, the receiving plate 84 or the magnetic powder channel 82, which would affect the subsequent recovery of the nano-magnetic powder.
