Description

Technical Field

[0001] This invention relates to the field of metal material recycling technology, specifically to a device for detecting impurities in recycled aluminum melt based on electromagnetic separation. Background Technology

[0002] In recent years, with the advancement of aluminum alloy processing technology and the continuous expansion of its application scope, aluminum has become the second most consumed metal after steel. Due to the high energy consumption and pollution of the electrolytic aluminum industry, and the industry's past blind expansion of production capacity, it is necessary and promising to develop the waste aluminum recycling industry to meet the needs of sustainable aluminum resource development and greatly improve the recycling rate of aluminum resources. Recycled aluminum needs to be tested for impurities to determine its suitability for different applications, and this testing requires the molten aluminum to be thoroughly and uniformly mixed.

[0003] Citing Chinese patent publication number "CN214703187U", the invention includes a smelting furnace body and a casing. A controller is welded and fixed to the right side of the casing, and a liquid pump is installed on the left side of the casing. A first pipe is connected to the left side of the liquid pump, and a first valve is installed inside the first pipe. The end of the first pipe is connected to the smelting furnace body. Through the coordinated use of the first pipe, second pipe, third pipe, fourth pipe, liquid pump, first sensor, first valve, second valve, third valve, and fourth valve, automatic sampling and testing are achieved, and the molten aluminum alloy is then discharged back into the smelting furnace, reducing the risk of burns to workers.

[0004] However, existing technologies lack a uniform mixing device to evenly mix the recycled aluminum melt, making it inconvenient for testing devices to detect impurities in the recycled aluminum. Furthermore, the uneven mixing of the recycled aluminum melt leads to deviations in the test data. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for detecting impurities in recycled aluminum melt based on electromagnetic separation, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for detecting impurities in recycled aluminum melt based on electromagnetic separation, comprising a connecting pipe, a detection device fixedly connected to one end of the connecting pipe, a mixing chamber fixedly connected to the other end of the connecting pipe, a support column fixedly connected to the bottom of the mixing chamber, an electromagnetic control valve fixedly connected to the bottom of the mixing chamber, a driving mechanism fixedly connected to the top of the mixing chamber, the driving mechanism comprising a rotating shaft rotatably connected inside the mixing chamber, a barrier and protection mechanism fixedly connected to the surface of the rotating shaft, an impurity scraping mechanism fixedly connected to the surface of the rotating shaft, the impurity scraping mechanism comprising a connecting rod, an eddy current enhancement mechanism fixedly connected to the surface of the connecting rod, and a stirring mechanism fixedly connected to the surface of the rotating shaft; The impurity scraping mechanism includes: The first scraper is fixedly connected to the surface of the connecting rod; The second scraper is fixedly connected to the surface of the first scraper.

[0007] Preferably, there are two first scrapers, and the first scraper has an arc-shaped through hole inside, and the second scraper also has an arc-shaped through hole inside.

[0008] Preferably, the drive mechanism includes a support block, which is fixedly connected to the top of the mixing chamber. A first motor is fixedly connected to the top of the support block. A first gear is fixedly connected inside the first motor through an output shaft. The first gear meshes with a first gear belt, and the first gear belt meshes with a second gear. The second gear is fixedly connected to the surface of the rotating shaft.

[0009] Preferably, the barrier protection mechanism includes a second motor, which is fixedly connected to the top of the mixing chamber. A third gear is fixedly connected inside the second motor via an output shaft. The third gear meshes with a second gear belt, which meshes with a fourth gear belt. The fourth gear is fixedly connected to the surface of the rotating shaft, and a protective block is fixedly connected to the bottom of the fourth gear.

[0010] Preferably, the eddy current enhancement mechanism includes a fixing rod, which is fixedly connected to the surface of the connecting rod. The surface of the fixing rod is provided with a threaded groove, and there are two fixing rods.

[0011] Preferably, the surface of the fixed rod is rotatably connected to a vortex plate, and the surface of the vortex plate is provided with an arc-shaped groove.

[0012] Preferably, a spring is fixedly connected to the top of the vortex plate, and a swaying plate is fixedly connected to the top of the spring.

[0013] Preferably, the stirring mechanism includes a first stirring blade, which is fixedly connected to the surface of the rotating shaft, and a second stirring blade is fixedly connected to the surface of the first stirring blade.

[0014] This invention provides a device for detecting impurities in recycled aluminum melt based on electromagnetic separation. It has the following advantages: 1. This electromagnetic separation-based device for detecting impurities in recycled aluminum melt involves setting up a first scraper and a second scraper. A first motor is started, and through gear meshing, drives a rotating shaft to rotate, thereby rotating the first and second scrapers. This stirs the material while preventing recycled aluminum melt from adhering inside the mixing chamber, thus ensuring uniform stirring. Furthermore, arc-shaped through-holes are provided inside the first and second scrapers. These through-holes cause changes in direction and velocity of the fluid as it passes through, effectively breaking the laminar flow and promoting turbulence. This results in more uniform stirring, improved stirring efficiency, and a reduced deviation rate in subsequent detection data.

[0015] 2. This electromagnetic separation-based device for detecting impurities in recycled aluminum melt, by setting up a protective block, after starting the second motor, drives the protective block to rotate and adjust through gear meshing transmission. When stirring inside the mixing chamber, the inlet is closed, thereby avoiding unnecessary trouble caused by melt splashing to the outside of the mixing chamber during stirring, thus improving the safety of the device operation and reducing the deviation rate of subsequent detection data.

[0016] 3. This electromagnetic separation-based device for detecting impurities in recycled aluminum melt utilizes a vortex plate. When the rotating shaft drives the fixed rod to rotate, the melt flows through the arc-shaped grooves on the surface of the vortex plate, thereby enhancing the formation of vortices in the melt and making the mixing more uniform. Simultaneously, the forward and reverse rotation of the fixed rod causes the vortex plate to move up and down repeatedly, further enhancing the thorough mixing of the recycled aluminum melt and reducing the deviation rate of subsequent detection data. Furthermore, the vortex generated between the shaking plate and the vortex plate also causes the shaking plate to vibrate, further enhancing the mixing uniformity and reducing the deviation rate of subsequent detection data.

[0017] 4. The electromagnetic separation-based impurity detection device for recycled aluminum melt, by setting a first stirring blade and a second stirring blade, causes the axial flow of the melt, accelerates the rotation of the recycled aluminum melt inside the mixing box, thereby improving the uniform mixing of the melt and reducing the deviation rate of subsequent detection data.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0022] Example 1: Please refer to Figure 1-5The present invention provides a technical solution: a device for detecting impurities in recycled aluminum melt based on electromagnetic separation, comprising a connecting pipe 2, a detection device 1 fixedly connected to one end of the connecting pipe 2, a mixing chamber 3 fixedly connected to the other end of the connecting pipe 2, a support column 4 fixedly connected to the bottom of the mixing chamber 3, an electromagnetic control valve 10 fixedly connected to the bottom of the mixing chamber 3, a drive mechanism 5 fixedly connected to the top of the mixing chamber 3, the drive mechanism 5 comprising a rotating shaft 56, the rotating shaft 56 being rotatably connected inside the mixing chamber 3, a barrier protection mechanism 6 fixedly connected to the surface of the rotating shaft 56, an impurity scraping mechanism 7 fixedly connected to the surface of the rotating shaft 56, the impurity scraping mechanism 7 comprising a connecting rod 71, an eddy current enhancement mechanism 8 fixedly connected to the surface of the connecting rod 71, and a stirring mechanism 9 fixedly connected to the surface of the rotating shaft 56; The impurity scraping mechanism 7 includes: The first scraper 72 is fixedly connected to the surface of the connecting rod 71; The second scraper 73 is fixedly connected to the surface of the first scraper 72.

[0023] There are two first scrapers 72, and the interior of the first scraper 72 is provided with an arc-shaped through hole. The interior of the second scraper 73 is also provided with an arc-shaped through hole.

[0024] The drive mechanism 5 includes a support block 52, which is fixedly connected to the top of the mixing box 3. A first motor 51 is fixedly connected to the top of the support block 52. A first gear 53 is fixedly connected inside the first motor 51 through an output shaft. The first gear 53 is meshed with a first gear belt 54. The first gear belt 54 is meshed with a second gear 55, and the second gear 55 is fixedly connected to the surface of the rotating shaft 56.

[0025] The barrier protection mechanism 6 includes a second motor 61, which is fixedly connected to the top of the mixing box 3. A third gear 62 is fixedly connected inside the second motor 61 through an output shaft. The third gear 62 meshes with a second gear belt 63, which meshes with a fourth gear 64. The fourth gear 64 is fixedly connected to the surface of the rotating shaft 56, and a protective block 65 is fixedly connected to the bottom of the fourth gear 64.

[0026] In use, the second motor 61 is started. The start of the second motor 61 drives the third gear 62 to rotate via the output shaft. The rotation of the third gear 62 drives the second gear belt 63, which meshes with it, to rotate. The rotation of the second gear belt 63 drives the fourth gear 64 to rotate. The rotation of the fourth gear 64 causes the protective block 65 to be adjusted, thereby facilitating the feeding of recycled aluminum melt into the mixing tank 3. Then, the second motor 61 is started again to control the rotation of the protective block 65, thereby adjusting the size of the recycled aluminum melt inlet. Then, the first motor 51 is started. The start of the first motor 51 drives the first gear 53 to rotate via the output shaft. The rotation of the first gear 53 drives the first gear belt 54 to rotate. The rotation of the first gear belt 54 drives the second gear 55 to rotate. The rotation of the second gear 55 ultimately drives the rotating shaft 56 to rotate.

[0027] By setting the first scraper 72 and the second scraper 73, the first motor 51 is started and drives the rotating shaft 56 to rotate through the meshing transmission of gears, thereby driving the first scraper 72 and the second scraper 73 to rotate. While stirring, the recycled aluminum melt sticking inside the mixing box 3 is avoided, which affects the uniformity of stirring. Furthermore, the first scraper 72 and the second scraper 73 are provided with arc-shaped through holes. The arc-shaped through holes cause changes in the direction and speed of the fluid when it passes through, which can effectively break the laminar flow state and promote the formation of turbulence, thereby making the stirring more uniform, improving the stirring efficiency, and reducing the deviation rate of subsequent detection data.

[0028] By setting up a protective block 65, the second motor 61 is started and driven to rotate and adjust through gear meshing. When stirring inside the mixing chamber 3, the inlet is closed, thereby preventing the melt from splashing onto the outside of the mixing chamber 3 during stirring and causing unnecessary trouble. This improves the safety of the device operation and reduces the deviation rate of subsequent detection data.

[0029] Example 2: Please refer to Figure 1-8 Based on Embodiment 1, the present invention provides a technical solution: The eddy current enhancement mechanism 8 includes a fixed rod 81, which is fixedly connected to the surface of the connecting rod 71. The surface of the fixed rod 81 is provided with a threaded groove, and there are two fixed rods 81.

[0030] A vortex plate 83 is rotatably connected to the surface of the fixed rod 81, and an arc-shaped groove is formed on the surface of the vortex plate 83.

[0031] A spring 84 is fixedly connected to the top of the vortex plate 83, and a swaying plate 82 is fixedly connected to the top of the spring 84.

[0032] The stirring mechanism 9 includes a first stirring blade 91, which is fixedly connected to the surface of the rotating shaft 56, and a second stirring blade 92 is fixedly connected to the surface of the first stirring blade 91.

[0033] In use, when the rotating shaft 56 rotates, it will drive the first scraper 72, the second scraper 73, the fixed rod 81 and the first stirring blade 91 to rotate together. When the fixed rod 81 rotates, it will drive the vortex plate 83 and the shaking plate 82 to rotate together, thereby generating vortices between the vortex plate 83 and the shaking plate 82. This will cause the vortex plate 83 to slide on the surface of the fixed rod 81. When the vortex is generated, it will drive the shaking plate 82 to vibrate, further enhancing the generation of vortices, so that the recycled aluminum melt is mixed evenly, which will facilitate the accuracy of subsequent detection by the detection device.

[0034] By setting up the vortex plate 83, when the rotating shaft 56 drives the fixed rod 81 to rotate, the melt flows through the arc-shaped groove opened on the surface of the vortex plate 83, thereby enhancing the formation of melt vortices and making the stirring more uniform. At the same time, the forward and reverse rotation of the fixed rod 81 will also cause the vortex plate 83 to move up and down reciprocally, thereby further enhancing the thorough mixing of the recycled aluminum melt and reducing the deviation rate of subsequent test data. In addition, the vortex generated between the shaking plate 82 and the vortex plate 83 will also cause the shaking plate 82 to vibrate, further enhancing the mixing uniformity and thus reducing the deviation rate of subsequent test data.

[0035] By setting the first stirring blade 91 and the second stirring blade 92, the axial flow of the melt is caused, which accelerates the rotation of the recycled aluminum melt inside the mixing box 3, thereby improving the uniform mixing of the melt and reducing the deviation rate of subsequent detection data.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
