Description

Technical Field

[0001] The present invention relates to the technical field of waste metal recycling, and specifically to a waste aluminum product sorting and recycling device. Background Art

[0002] As our environmental requirements become increasingly high and people waste a large amount of energy, a lot of resources that can be utilized are lost in large quantities due to our negligence, which is undoubtedly a pity for our common mother earth, the planet. In order to respond to the country's call for renewable energy and actively cooperate with the national policy, we have specialized in the reuse of aluminum energy and currently have mastered a set of mature waste aluminum recycling technologies. Adhering to the people-oriented attitude, we have carried out a large amount of recycling of our discarded aluminum products. Such measures will undoubtedly reduce the waste of some non-renewable energy for the reuse of metal energy. However, in the process of recycling waste aluminum products, aluminum products are often used in combination with other materials, so that waste items often include other non-ferrous metals, iron, and plastic products. For example, there are plastics, aluminum alloys, stainless steels, and iron in aluminum alloy doors and windows, which shows that aluminum products are often used in combination with other materials, so that it is necessary to sort them first when recycling waste aluminum products. In order to quickly classify waste metals for easy recycling, a eddy current separator is used for classification.

[0003] The eddy current separator is designed based on the principle that a conductor generates an induced current in a high-frequency alternating magnetic field. During operation, a high-frequency alternating magnetic field is generated on the surface of the sorting magnetic roller. When a conductive non-ferrous metal passes through the magnetic field, an eddy current will be induced in the non-ferrous metal. This eddy current itself will generate a magnetic field opposite to the direction of the original magnetic field. Non-ferrous metals (such as copper, aluminum, etc.) will leap forward along their transportation direction due to the repulsive force of the magnetic field to achieve separation from other non-conductive or non-metallic substances, achieving the purpose of sorting. However, the existing eddy current separator has certain limitations when sorting aluminum alloy doors and windows. Due to its structural characteristics, when the waste particle materials after passing through the strong magnetic machine are sorted by eddy current, the sizes of the entering material particles cannot vary too much, otherwise the sorted materials will be inaccurate. This requires the secondary crushing of the crushed waste products before using the eddy current separator to make the particle diameters of the particles uniform, resulting in too many steps and consuming a large amount of energy. Moreover, after sorting by eddy current, since copper alloy may be mixed during the manufacturing process of aluminum alloy, such as the hinges in aluminum alloy doors and windows may use copper alloy. Although copper alloy is more expensive than aluminum alloy, due to its good performance in various aspects, the separated aluminum alloy will be mixed with copper alloy, and it is necessary to perform secondary separation on it, which not only affects the sorting effect but also increases energy consumption. Summary of the Invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution significantly different from the existing technologies. An embodiment of the present invention provides a waste aluminum product sorting and recycling device to solve the technical problem that the existing eddy current separator cannot effectively sort aluminum products and copper with different particle sizes.

[0005] The embodiment of the present invention adopts the following technical solution: A waste aluminum product sorting and recycling device includes a feeding plate for feeding waste products that are broken and preliminarily separated by a strong magnetic machine, and also includes a multi-diameter sorting mechanism for classifying waste products with different particle sizes, a floating object removing mechanism for recycling non-conductive products floating on the liquid surface after classification, and a recycling mechanism for classifying and recycling waste products after being sorted by the multi-diameter sorting mechanism. The floating object removing mechanism is arranged at the top of the multi-diameter sorting mechanism, the recycling mechanism is arranged at the bottom of the multi-diameter sorting mechanism, and the feeding plate penetrates through the multi-diameter sorting mechanism.

[0006] Further, the multi-diameter sorting mechanism includes a sorting barrel. One side of the upper end of the sorting barrel penetrates through the feeding plate. A sorting magnetic roller is rotatably connected to the central position of the sorting barrel. A sorting auger blade is arranged around the outside of the sorting magnetic roller. Separation blocks are arranged in the upper half of the sorting auger blade, and a plurality of sorting plates are arranged in the lower half of the sorting auger blade. A number of screening holes are opened in each sorting plate.

[0007] Further, the diameters of the screening holes opened in the plurality of sorting plates increase sequentially from the inside to the outside. The sorting plates are arranged around the sorting auger blade. The sorting plates are inclined between the sorting auger blade. The cross-section of the sorting auger blade gradually increases from the inside to the outside. The sorting auger blade is fixedly connected to the sorting magnetic roller.

[0008] Further, the setting direction of the sorting auger blade is the same as the rotation direction of the sorting magnetic roller.

[0009] Further, the floating object removing mechanism includes a connecting column arranged on the top of the sorting magnetic roller. A number of scraping plates are arranged outside the connecting column. A guiding plate is arranged on one side of each scraping plate. A limiting plate is arranged at the end of each guiding plate. A collecting box is arranged outside the upper end of the sorting barrel. The cross-section of the collecting box is U-shaped. A concentrating block is arranged in the collecting box. A connecting rod is arranged at the end of the concentrating block. The connecting rod is connected to the connecting column.

[0010] Further, the cross-section of the scraping plate is inclined, and the guiding plate is arranged at the highest point of the scraping plate. The cross-section of the scraping plate is U-shaped, and the height of the scraping plate gradually decreases from the inside to the outside. The lowest point of the outer end of the scraping plate is at the same height as the top end of the sorting barrel.

[0011] Further, the recycling mechanism includes a classification and recycling plate fixedly arranged above the bottom plate of the sorting barrel. A plurality of discharge ports are formed in the bottom plate of the sorting barrel. A discharge plate is arranged below each port. A sieve plate is arranged below the bottom end of the sorting barrel. A water collecting tank is arranged below the sieve plate. A driving motor is arranged below the sorting plate, and the driving motor is used to drive the sorting magnetic roller to rotate.

[0012] Further, the position of the classification and recycling plate corresponds to the position of the sorting plate, and the cross-section of the classification and recycling plate is annular.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] First, the multi-diameter feeding mechanism can classify waste products with different particle sizes, solving the problem that the existing eddy current sorting will affect the sorting effect if the particle sizes after crushing vary greatly. Moreover, the multi-diameter feeding mechanism can also separate copper and aluminum mixed together. Since there is brine liquid in the multi-diameter mechanism, at this time, the plastic can be separated by the brine liquid. Because the density of the plastic is less than that of the brine liquid, the plastic in the waste products entering the sorting barrel will float under the action of the buoyancy of the brine, and the rest of the waste products will sink. And the brine can not only play a role in separating the plastic from the rest of the waste products, but also increase the sinking time of the rest of the waste products through the brine, thereby increasing the contact time between the multi-diameter feeding mechanism and the rest of the waste products, making the sorting effect of the multi-diameter feeding mechanism better;

[0015] And during use, since separation blocks are provided in the sorting and selecting screw blades of the multi-diameter material distribution mechanism, when the waste products move along the sorting screw blades, the waste products will come into contact with the separation blocks at this time. Under the action of the separation blocks, the waste products can be scattered, preventing the edges of the waste products from being irregular when they are crushed, and preventing the edges from catching other plastics, which would cause the plastics to sink synchronously, thereby increasing the sorting effect. And because the sorting magnetic roller is located at the middle position of the sorting screw blades, at this time, the separation of plastics and waste metal products can also be achieved under the action of the sorting magnetic roller, increasing the sorting effect of the device. When the waste products move to the sorting screw blades at the lower part, since the sorting screw blades are inclined, the waste products will be concentrated near the sorting magnetic roller. At this time, the sorting screw blades will rotate under the action of the sorting magnetic roller. However, because the waste products are in contact with the sorting screw blades and the sorting screw blades are inclined, when the sorting screw blades rotate, a centrifugal force will be applied to the waste products. At this time, under the action of the centrifugal force, the larger particle waste products will receive a greater centrifugal force. At this time, the waste particles will move away from the sorting magnetic roller under the action of the centrifugal force. And there are multiple sorting plates on the sorting magnetic roller. The waste particles will be sorted under the action of the sorting plates. At the same time, because there is a certain inclination angle between the sorting plates and the sorting screw blades, under the action of the sorting plates, the sorting screw blades have three layers, causing some waste products with larger particles but insufficient quality to be unable to be centrifuged normally due to the influence of the inclination angle. However, because their particles are larger and their mass is greater than that of the smaller particles, they are separated from the smaller particle waste products. At the same time, because the density of the mixed aluminum products and copper products is different, the aluminum products and copper products at the same layer after preliminary sorting will be secondarily sorted due to the influence of density, so that the waste products finally entering the recycling mechanism can not only sort the materials, but also sort the particle sizes. This makes the sorting device not only not affected by the particle size of the waste products, but also can sort the waste products into particle waste, increasing the sorting effect, so that before eddy current sorting, the waste products do not need to be evenly crushed by other machines, effectively reducing energy consumption;

[0016] Second, the floating object removal mechanism can automatically remove the sorted plastics without manual operation. When removing plastics, the power source used at this time is the power generated by the rotation of the sorting magnetic roller, reducing the energy consumption of the device. During use, the scraper rotates with the connecting column. Due to the shape characteristics of the scraper, when the scraper rotates, it can collect the plastics floating on the surface of the brine. The collected plastics enter the collection box through the guide plate, thus playing the role of automatically collecting plastics. At the same time, when the recycling mechanism recycles the waste products after sorting, it can collect the brine, facilitating the recycling of the brine, reducing the sorting cost. At the same time, because the device improves the sorting effect, effectively recycles aluminum products, reduces the waste of aluminum products, and increases the environmental protection of the device;

[0017] In summary, when the device is in use, it only needs to crush the waste products and remove iron by the strong magnetic machine, without the need to make the crushed particles uniform. At the same time, it can sort different aluminum products and copper products in the waste products. Through one device, not only can plastics and metal products be sorted, but also different metal products can be sorted. And during the sorting process, it is not affected by the particle size, and at the same time, it can also sort different sized particles, effectively increasing the sorting efficiency and sorting effect.

[0032] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] As shown below in conjunction with Figures 1 to 7 Figures 1 to 7 shows that an embodiment of the present invention provides a waste aluminum product sorting and recycling device, including a feed plate 4 for feeding waste products that are preliminarily separated by a high-intensity magnetic separator after being crushed, and further including a multi-diameter sorting mechanism 2 for classifying waste products of different particle sizes, a floating matter removal mechanism 1 for recycling non-conductive products that float on the liquid surface after classification, and a recycling mechanism 3 for classifying and recycling waste products after being sorted by the multi-diameter sorting mechanism 2. The floating matter removal mechanism 1 is arranged at the top of the multi-diameter sorting mechanism 2, the recycling mechanism 3 is arranged at the bottom of the multi-diameter sorting mechanism 2, and the feed plate 4 penetrates through the multi-diameter sorting mechanism 2.

[0034] During operation, when using this device, it only needs to crush the waste products and remove iron by a high-intensity magnetic separator. It is not necessary to make the crushed particles uniform. At the same time, different aluminum products and copper products in the waste products can be sorted. Through one device, not only can plastic and metal products be sorted, but also different metal products can be sorted. Moreover, during the sorting process, it is not affected by the particle size, and different-sized particles can also be sorted, effectively increasing the sorting efficiency and sorting effect.

[0035] Specifically, the multi-diameter sorting mechanism 2 includes a sorting barrel 21. One side of the upper end of the sorting barrel 21 penetrates through the feed plate 4. A sorting magnetic roller 24 is rotatably connected at the central position of the sorting barrel 21. A sorting auger blade 22 is arranged around the outside of the sorting magnetic roller 24. Separation blocks 23 are arranged in the upper half of the sorting auger blade 22, and a plurality of sorting plates 25 are arranged in the lower half of the sorting auger blade 22. A number of screening holes 26 are opened in each sorting plate 25.

[0036] Specifically, the diameters of the screening holes 26 opened in the plurality of sorting plates 25 increase sequentially from the inside to the outside. The sorting plates 25 are arranged around the sorting auger blade 22. The sorting plates 25 are inclined with respect to the sorting auger blade 22. The cross-section of the sorting auger blade 22 gradually increases from the inside to the outside. The sorting auger blade 22 is fixedly connected to the sorting magnetic roller 24.

[0037] During operation, through the inclined setting, when centrifuging, although the waste products with lighter mass are also affected by the centrifugal force, they cannot be effectively centrifuged, thus playing a role in sorting.

[0038] Specifically, the setting direction of the sorting auger blade 22 is the same as the rotation direction of the sorting magnetic roller 24.

[0039] During operation, since the sorting auger blade 22 and the sorting magnetic roller 24 rotate in the same direction, when the waste products fall onto the sorting auger blade 22, under the action of the sorting magnetic roller 24 at this time, the waste products are repelled. After being repelled, the waste products come into contact with the sorting auger blade 22. At the same time, due to the same-direction rotation, the contact time between the waste products and the sorting auger blade 22 can be effectively increased, thereby slowing down the moving speed of the waste products and making the sorting effect of the waste products better.

[0040] Specifically, the floating object removal mechanism 1 includes a connecting column. The connecting column is arranged on the top of the sorting magnetic roller 24. A plurality of scraping plates 14 are arranged outside the connecting column. One side of each scraping plate 14 is provided with a guiding plate 15. The end of each guiding plate 15 is provided with a limiting plate 16. A collecting box 13 is arranged outside the upper end of the sorting barrel 21. The cross section of the collecting box 13 is U-shaped. A concentrating block 12 is arranged inside the collecting box 13. One end of the concentrating block 12 is provided with a connecting rod 11, and the connecting rod 11 is connected to the connecting column.

[0041] Specifically, the cross section of the scraping plate 14 is inclined, and the guiding plate 15 is arranged at the highest point of the scraping plate 14. The cross section of the scraping plate 14 is U-shaped, and the height of the scraping plate 14 gradually decreases from the inside to the outside. The lowest point of the outer end of the scraping plate 14 is at the same height as the top end of the sorting barrel 21.

[0042] During operation, since the cross section of the scraping plate 14 is inclined, when the scraping plate 14 comes into contact with the floating plastic at this time, the floating plastic will be affected by the inclined surface of the scraping plate 14 and play a certain guiding role, so that the plastic will move along the inclined surface of the scraping plate 14. Finally, the floating plastic will enter the collecting box 13, enabling the device to automatically collect the floating plastic without the need for an additional power source during collection.

[0043] Specifically, the recycling mechanism 3 includes a classification recycling plate 31. The classification recycling plate 31 is fixedly arranged above the bottom plate of the sorting barrel 21. A plurality of discharge ports 32 are opened in the bottom plate of the sorting barrel 21. A discharge plate 33 is arranged below each discharge port 32. A sieve plate 34 is arranged below the bottom end of the sorting barrel 21. A water collecting tank 35 is arranged below the sieve plate 34. A driving motor 36 is arranged below the sorting plate 25, and the driving motor 36 is used to drive the sorting magnetic roller 24 to rotate.

[0044] Specifically, the position of the classification recycling plate 31 corresponds to the position of the sorting plate 25, and the cross section of the classification recycling plate 31 is annular.

[0045] During operation, through the arrangement of a plurality of classification recycling plates 31, the sorted waste products can be recycled.

[0046] Working principle: When in use, first crush the waste products of aluminum alloy doors and windows, and then preliminarily separate the crushed waste products through a strong magnetic separator so that the iron in the waste products is separated. Then, the preliminarily separated waste products enter the collection box 13 through the feeding plate 4. Since the diameter of the sorting auger blade 22 is the same as the inner diameter of the collection box 13, the waste products entering the collection box 13 at this time will fall onto the sorting auger blade 22. Due to the sorting magnetic roller 24 being driven by the drive motor 36 to rotate, and the sorting auger blade 22 being connected to the sorting magnetic roller 24, the sorting auger blade 22 will rotate synchronously with the sorting magnetic roller 24. And because the collection box 13 is filled with brine, at this time, under the action of the brine, the falling speed of the waste products can be slowed down to prevent the waste products from directly hitting the sorting auger blade 22. When the waste products falling onto the sorting auger blade 22 are affected by the sorting auger blade 22 and move, but since there is a sorting magnetic roller 24 in the middle position of the sorting auger blade 22, and there are separation blocks 23 on the upper part of the sorting auger blade 22, during the movement of the waste products, they will touch the separation blocks 23. Under the action of the separation blocks 23, it can be avoided that the edges of the waste products are uneven due to irregular crushing during crushing, so that sticking may occur between the waste products. At this time, under the action of the separation blocks 23, the waste products sticking together can be separated, and at the same time, secondary separation is carried out under the action of the sorting magnetic roller 24 to increase the separation effect. The plastic in the separated waste products floats under the action of the brine, so that the plastic in the waste products is separated. At this time, the remaining aluminum alloy and copper alloy in the waste products gradually move downward under the influence of the sorting auger blade 22. At the same time, since the setting direction of the sorting auger blade 22 is the same as the rotation direction of the sorting magnetic roller 24, when the waste products move, the contact time can be increased, thereby prolonging the movement time of the waste products and making the separation effect of the waste products better. When the waste products move to the sorting auger blade 22 at the lower part, since the sorting auger blade 22 is inclined, the waste products will be concentrated near the sorting magnetic roller 24. At this time, the sorting auger blade 22 will rotate under the action of the sorting magnetic roller 24. However, since the waste products are in contact with the sorting auger blade 22 and the sorting auger blade 22 is inclined, when the sorting auger blade 22 rotates, a centrifugal force will be applied to the waste products. At this time, under the action of the centrifugal force, the larger particles of the waste products are subjected to a greater centrifugal force. At this time, the waste particles are affected by the centrifugal force and move away from the sorting magnetic roller 24. And there are multiple sorting plates 25 on the sorting magnetic roller 24. The waste particles will be sorted under the action of the sorting plates 25. At the same time, since there is a certain inclination angle between the sorting plates 25 and the sorting auger blade 22, under the action of the sorting plates 25, the sorting auger blade 22 has three layers, so that some waste products with larger particles but insufficient quality cannot be centrifuged normally due to the influence of the inclination angle. However, since their particles are larger, their mass is greater than that of the smaller particles.Thus, it enables sorting with waste products of smaller particles. At the same time, since the density of the mixed aluminum products and copper products is different, the aluminum products and copper products on the same layer after preliminary sorting will be sorted again under the influence of density. When the waste products move to the bottom, under the centrifugal force, waste products of the same size and material will enter the corresponding classification and recycling plates 31, so that the waste products finally entering the recycling mechanism 3 can not only sort the materials, but also sort the particle sizes. This sorting device is not only not affected by the particle size of the waste products, but also can process the waste products into particle waste, increasing the sorting effect. Before eddy current sorting, the waste products do not need to be evenly crushed by other machinery, effectively reducing energy consumption. Since the connecting column is connected to the sorting magnetic roller 24, when the sorting magnetic roller 24 rotates, the connecting column will also rotate synchronously. At the same time, since the scraper 14 is connected to the connecting column, the scraper 14 will rotate with the connecting column. Due to the shape characteristics of the scraper 14, when the scraper 14 rotates, it can collect the plastics floating on the surface of the brine. The collected plastics will enter the collection box 13 through the guide plate, thus playing the role of automatically collecting plastics. At the same time, when the recycling mechanism 3 recycles the sorted waste products, it can collect the brine, which is convenient for recycling the brine and reducing the sorting cost. At the same time, since this device improves the sorting effect, it effectively recovers aluminum products, reduces the waste of aluminum products, and increases the environmental protection of the device. When it is necessary to take out the sorted waste products, pull the discharge plate 33, and the waste products in the classification and recycling plate 31 will come out through the discharge port 32, and the brine will also flow out. However, since a sieve plate 34 is provided below the discharge plate 33, the brine and the waste products can be separated under the action of the sieve plate 34, and the brine enters the water collection tank 35, which is convenient for recycling the brine.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
