Description

Technical Field

[0001] This utility model relates to the technical field of waste aluminum recycling equipment, and more specifically, to a waste aluminum recycling device. Background Technology

[0002] Aluminum, as a lightweight, corrosion-resistant, and electrically conductive metal, has wide applications in aerospace, automotive manufacturing, construction, packaging, and many other fields. However, with the large-scale use and replacement of aluminum products, the amount of scrap aluminum generated is also constantly increasing. If this scrap aluminum is not effectively recycled and utilized, it will not only waste resources but also pollute the environment. Therefore, scrap aluminum recycling has become an important link in the industrial chain, and is of great significance for realizing the circular reuse of resources and protecting the environment.

[0003] Because scrap aluminum often contains scrap iron, and the presence of scrap iron impurities is detrimental to the recycling and resmelting of scrap aluminum, it is necessary to screen and remove the scrap iron impurities before crushing and collecting the scrap aluminum. To effectively remove the scrap iron component from scrap aluminum, Chinese utility model patent CN218609729U discloses a scrap aluminum recycling device. This device, by setting up a filter screen and a magnetic layer on the conveyor belt, can achieve initial processing, crushing, and screening of scrap aluminum, and effectively remove the scrap iron component.

[0004] However, in the aforementioned waste aluminum recycling device, the waste iron impurities adsorbed on the magnetic layer of the conveyor belt need to be removed manually. It cannot automatically remove the waste iron impurities on the magnetic layer during waste aluminum crushing and screening. Not only is the degree of automation low, but there are also certain safety hazards, which are not conducive to the personal safety of operators. Its structure needs to be improved. Utility Model Content

[0005] To address the shortcomings of existing waste aluminum recycling devices, such as their inability to automatically remove iron impurities from the magnetic layer during waste aluminum crushing and screening, resulting in low automation, safety hazards, and risks to operator health, this invention provides a waste aluminum recycling device. This device utilizes a cleaning mechanism located directly beneath the conveyor belt. A scraper within this mechanism automatically removes iron impurities adsorbed on the magnetic layer, eliminating the need for manual operation. This not only improves overall automation but also ensures operator safety. The specific technical solution is as follows:

[0006] A waste aluminum recycling device includes a conveyor belt and a waste aluminum processing mechanism. The conveyor belt has a magnetic layer, and the waste aluminum processing mechanism includes a feed inlet. The output end of the conveyor belt is adjacent to the feed inlet. The waste aluminum processing mechanism is used to crush and recycle waste aluminum. The waste aluminum recycling device also includes a cleaning mechanism located directly below the conveyor belt, the cleaning mechanism comprising:

[0007] A scraper is located directly below the conveyor belt, with one end in contact with the surface of the magnetic layer located below the conveyor belt.

[0008] An inclined plate, one end of which is fixedly connected to the other end of the scraper;

[0009] The baffle is fixedly installed on both sides of the inclined plate and extends toward the waste aluminum processing mechanism;

[0010] A scrap metal collection assembly includes a scrap metal collection box, the top of which is provided with a second feed inlet located directly below the other end of the inclined plate.

[0011] The waste aluminum recycling device has a cleaning mechanism set directly below the conveyor belt. The scraper, which is attached to the surface of the magnetic layer, can automatically scrape off and remove the waste iron impurities adsorbed on the magnetic layer, so as to facilitate the subsequent process of crushing and recycling the waste aluminum after removing the waste iron components. By setting up an inclined plate and baffles installed on both sides of the inclined plate and extending towards the waste aluminum processing mechanism, the waste iron impurities scraped off from the magnetic layer can fall smoothly into the waste iron collection box in the waste iron collection assembly for recycling.

[0012] In other words, the waste aluminum recycling device has a cleaning mechanism set directly below the conveyor belt. The scraper in the cleaning mechanism automatically scrapes off the waste iron impurities adsorbed on the magnetic layer without manual operation. This not only improves the overall automation level, but also ensures the personal safety of the operators.

[0043] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0044] Existing waste aluminum recycling devices rely on manual removal of waste iron impurities adsorbed on the magnetic layer, which has the following drawbacks:

[0045] 1. Relying on manual cleaning is time-consuming, labor-intensive, and has a low degree of automation. 2. Since the conveyor belt is generally in operation during the waste aluminum recycling process, relying on manual cleaning can easily endanger the personal safety of operators if not handled carefully, posing certain safety hazards.

[0046] In addition, existing waste aluminum recycling devices have the following drawbacks:

[0047] 3. The waste aluminum recycling device is equipped with a first box, a second box, and a third box, and corresponding crushing and grinding devices are installed in the second box and the third box. The overall structure is relatively complex, which increases the cost of the equipment. There is room for further simplification of its structure.

[0048] 4. In the first chamber, the scrap aluminum that comes in from the feed hopper has not undergone crushing before being crushed by the crushing device installed in the first chamber. The scrap aluminum has a large volume, which is not conducive to crushing the scrap aluminum. Furthermore, the volume after crushing is also large, which is not conducive to subsequent extrusion and recycling.

[0049] To address one of the problems existing in the prior art of waste aluminum recycling devices, this embodiment provides a waste aluminum recycling device, such as... Figure 1 As shown, it includes a conveyor belt 1 and a waste aluminum processing mechanism 3. The conveyor belt 1 is provided with a magnetic layer 2. The waste aluminum processing mechanism 3 includes a feed inlet 30. The output end of the conveyor belt 1 is adjacent to the feed inlet 30. The waste aluminum processing mechanism 3 is used to crush and recycle waste aluminum.

[0050] The conveyor belt 1 is driven by a motor to move back and forth, transporting the waste aluminum from the input end to the output end. The waste iron impurities in the waste aluminum are adsorbed by the magnetic layer 2 and remain on the magnetic layer 2. The waste aluminum after the waste iron impurities are adsorbed falls from the output end of the conveyor belt 1 into the feed inlet 30, and then undergoes crushing and recycling.

[0051] The waste aluminum recycling device also includes a cleaning mechanism 4 located directly below the conveyor belt 1. The cleaning mechanism 4 includes a scraper 40, an inclined plate 41, a baffle 42, and a waste iron collection component 43.

[0052] The scraper 40 is located directly below the conveyor belt 1 and one end is in contact with the surface of the magnetic layer 2 located below the conveyor belt 1; one end of the inclined plate 41 is fixedly connected to the other end of the scraper 40.

[0053] The baffle 42 is fixedly installed on both sides of the inclined plate 41 and extends toward the waste aluminum processing mechanism 3; the waste iron collection assembly 43 includes a waste iron collection box 430, and the top of the waste iron collection box 430 is provided with a second feed port 30 located directly below the other end of the inclined plate 41.

[0054] The baffle 42 can be vertically installed on both sides of the inclined plate 41. Preferably, the baffle 42 is inclined relative to the inclined plate 41, and the baffle 42 and the inclined plate 41 are integrally formed to improve their overall strength. The cross-section of the baffle 42 and the inclined plate 41 along the width direction is funnel-shaped, and the funnel shape faces the waste aluminum processing mechanism 3.

[0055] The magnetic layer 2 can be formed by uniformly distributing magnets on the surface of the conveyor belt 1.

[0056] The waste aluminum recycling device has a cleaning mechanism 4 set directly below the conveyor belt 1. The scraper 40, which is attached to the surface of the magnetic layer 2, can automatically scrape off and remove the waste iron impurities adsorbed on the magnetic layer 2, so as to facilitate the subsequent process of crushing and recycling the waste aluminum after removing the waste iron components. By setting up an inclined plate 41 and baffles 42 installed on both sides of the inclined plate 41 and extending towards the waste aluminum processing mechanism 3, it is beneficial for the waste iron impurities scraped off from the magnetic layer 2 to fall smoothly into the waste iron collection box 430 in the waste iron collection assembly 43 for waste iron recycling.

[0057] In summary, the waste aluminum recycling device, by setting a cleaning mechanism 4 directly below the conveyor belt 1, automatically scrapes off the waste iron impurities adsorbed on the magnetic layer 2 through the scraper 40 in the cleaning mechanism 4, without the need for manual operation. This not only improves the overall automation level but also ensures the personal safety of the operators.

[0058] Existing waste aluminum recycling devices suffer from relatively complex overall structures, which increases equipment costs and hinders the crushing and subsequent compression recycling of waste aluminum.

[0059] To address the aforementioned issues, as a preferred technical solution, the waste aluminum processing mechanism 3 further includes a waste aluminum collection box 31, a first crushing component 32, a crushing component 33, and a second crushing component 34.

[0060] The top of the waste aluminum collection box 31 is provided with a waste aluminum collection port that communicates with the feed inlet 30. The feed inlet 30 is funnel-shaped to facilitate the falling of waste aluminum.

[0061] The first crushing assembly 32, the crushing assembly 33, and the second crushing assembly 34 are all fixedly installed in the waste aluminum collection box 31 and arranged sequentially from top to bottom.

[0062] Specifically, the first rolling assembly 32 includes a first active rolling roller 320, a first driven rolling roller 321, and a drive unit.

[0063] Both the first active rolling roller 320 and the first driven rolling roller 321 are rotatably mounted in the waste aluminum collection box 31 via a rotating shaft; the drive unit is fixedly mounted in the waste aluminum collection box 31, and is connected to the first active rolling roller 320 for driving the first active rolling roller 320 to rotate.

[0064] Here, the drive unit may be an electric motor, which is connected to the first active roller 320 via a belt.

[0065] The first active roller 320 and the first driven roller 321 are located on the same horizontal plane, and a first gap is provided between the first active roller 320 and the first driven roller 321 located directly below the feed inlet 30.

[0066] The crushing assembly 33 includes an active cutting blade 330 and a driven cutting blade 331. Both the active cutting blade 330 and the driven cutting blade 331 are rotatably mounted in the waste aluminum collection box 31 via a rotating shaft.

[0067] The drive unit is also connected to the active cutting blade 330 and is used to drive the active cutting blade 330 to rotate. The active cutting blade 330 meshes with the driven cutting blade 331 and the tangent of the meshing point is located directly below the first gap.

[0068] The second crushing assembly 34 includes a second active crushing roller 340 and a second driven crushing roller 341. Both the second active crushing roller 340 and the second driven crushing roller 341 are rotatably mounted in the waste aluminum collection box 31 via a rotating shaft.

[0069] The drive unit is also connected to the second active roller 340 and is used to drive the second active roller 340 to rotate. The axes of the second active roller 340 and the second driven roller 341 are located on the same horizontal plane. A second gap is provided between the second active roller 340 and the second driven roller 341 located directly below the feed inlet 30.

[0070] Preferably, the dividing plane of the first gap along the width direction, the dividing plane of the second gap along the width direction, and the tangent of the engagement point are on the same vertical plane.

[0071] The drive unit can also be connected to the active cutting blade 330 and the second active pressing roller 340 via a belt. Driving the active cutting blade 330, the second active pressing roller 340, and the first active pressing roller 320 with the same drive unit can reduce equipment costs and simplify the structure.

[0072] By sequentially arranging a first crushing assembly 32, a crushing assembly 33, and a second crushing assembly 34 from top to bottom in the waste aluminum collection box 31, the first crushing assembly 32 first crushes the waste aluminum falling from the feed inlet 30, reducing its volume and facilitating the crushing assembly 33's pulverization of the waste aluminum. The pulverized waste aluminum is then further crushed by the second crushing assembly 34, which flattens the cut and pulverized waste aluminum into flakes, further reducing its volume for subsequent compression and recycling.

[0073] In addition, by setting a first crushing component 32, a crushing component 33 and a second crushing component 34 in the waste aluminum collection box 31, the waste aluminum recycling device of the present invention reduces the number of boxes and crushing components 33 compared with the waste aluminum recycling device in the prior art, simplifies the structure and helps to reduce equipment costs.

[0074] As a preferred technical solution, such as Figure 2 As shown, the waste aluminum processing mechanism 3 also includes a first extrusion assembly, which is installed at the bottom of the waste aluminum collection box 31 and is used to extrude the waste aluminum located at the bottom of the waste aluminum collection box 31.

[0075] The first extrusion assembly includes a first extrusion plate 35 and a first pushing unit 36. The first extrusion plate 35 is installed at the bottom of the waste aluminum collection box 31 and is slidably connected to the bottom of the inner sidewall of the waste aluminum collection box 31; the first pushing unit 36 ​​is installed in the waste aluminum collection box 31 and is used to drive the first extrusion plate 35 to slide relative to the bottom of the inner sidewall of the waste aluminum collection box 31.

[0076] The scrap metal collection assembly 43 also includes a second compression assembly, such as... Figure 3 As shown, the second extrusion assembly is installed at the bottom of the scrap metal collection box 430 and is used to extrude scrap metal located at the bottom of the scrap metal collection box 430.

[0077] The second extrusion assembly includes a second extrusion plate 431 and a second pushing unit 432.

[0078] The second extrusion plate 431 is installed at the bottom of the scrap metal collection box 430 and is slidably connected to the bottom of the inner sidewall of the scrap metal collection box 430. The second pushing unit 432 is installed in the scrap metal collection box 430 and is used to drive the second extrusion plate 431 to slide relative to the bottom of the inner sidewall of the scrap metal collection box 430.

[0079] The first pushing unit 36 ​​and the second pushing unit 432 have the same structure, each including a motor 5, a gear 6 fixedly mounted on the output shaft of the motor, and a rack 7 meshing with the gear. The motors of the first pushing unit 36 ​​and the second pushing unit 432 are respectively fixedly mounted on the bodies of the waste aluminum collection box 31 and the waste iron collection box 430. The racks of the first pushing unit 36 ​​and the second pushing unit 432 respectively move through the side walls of the bodies of the waste aluminum collection box 31 and the waste iron collection box 430, and are respectively fixedly connected to the first extrusion plate 35 and the second extrusion plate 431. The output shaft of the motor 5 passes through the center of the gear 6 and is fixedly connected to the gear 6.

[0080] By setting the first extrusion assembly and the second extrusion assembly, the scrap aluminum in the scrap aluminum collection box 31 and the scrap iron in the scrap iron collection box 430 can be extruded to reduce their volume and facilitate storage and transportation.

[0081] The specific working principle of this utility model is as follows: Scrap aluminum is transported to the input end of conveyor belt 1 and then conveyed to the feed inlet 30 via conveyor belt 1. During this process, the magnetic force of the magnetic layer 2 adsorbs the scrap iron impurities in the scrap aluminum. The scraper 40 adheres to the surface of the magnetic layer 2, scraping off and removing the scrap iron impurities adsorbed on the magnetic layer 2. The scrap iron impurities fall down and through the inclined plate 41 into the scrap iron collection box 430 in the scrap iron collection assembly 43. After the scrap iron impurities are adsorbed, the scrap aluminum falls into the scrap aluminum collection box 31 through the feed inlet 30. It is then crushed by the first crushing assembly 32, pulverized by the crushing assembly 33, and crushed again by the second crushing assembly 34, and then crushed into sheet-like scrap aluminum. Finally, the first extrusion assembly is activated, and the first pushing unit 36 ​​pushes the first extrusion plate 35 to slide relative to the bottom of the inner wall of the scrap aluminum collection box 31, and extrudes the scrap aluminum located at the bottom of the scrap aluminum collection box 31 to facilitate the storage and transportation of scrap aluminum. Simultaneously, the second extrusion assembly is activated, and the second pushing unit 432 pushes the second extrusion plate 431 to slide relative to the bottom of the inner wall of the scrap iron collection box 430, and extrudes the scrap iron located at the bottom of the scrap iron collection box 430 in order to facilitate the storage and transportation of scrap iron.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
