Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waste aluminum screening, in particular to a waste aluminum screening production line. Background Art
[0002] Automated sorting technology has made significant progress in the scrap aluminum recycling and reuse industry, significantly improving the efficiency and accuracy of scrap aluminum sorting. However, while automated sorting systems effectively remove most impurities from scrap aluminum, due to the diverse and complex sources of scrap aluminum, some unpredictable impurities and dust may remain in the sorted scrap. To ensure accurate scrap aluminum sorting, many companies use manual screening to perform a secondary screening of the automatically sorted scrap. However, in this secondary screening process, the scrap aluminum directly enters the manual screening stage after automatic sorting without undergoing dust removal. Dust, fine metal particles, and other impurities adhering to the scrap surface are kicked up by workers as they turn and sort the scrap. This raised dust not only reduces visibility in the work environment and increases the difficulty of sorting, but more importantly, poses a direct threat to worker health. Therefore, improvements to existing technologies are necessary to address these issues. Utility Model Content

[0025] The present invention will be described in detail below with reference to specific embodiments.
[0026] In the present utility model, unless otherwise expressly provided and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are for the purpose of better explaining the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.
[0027] The utility model provides a waste aluminum screening production line, such as Figures 1 to 4 As shown, it includes a feed hopper 1, a feed conveying mechanism 2, a dust removal mechanism 3, a manual screening mechanism 4 and a discharge box 5; the scrap aluminum is transported from the feed hopper 1 to the dust removal mechanism 3 by the feed conveying mechanism 2 and then enters the manual screening mechanism 4. After manual screening, the remaining scrap aluminum enters the discharge box 5;
[0028] The manual screening mechanism 4 includes a workbench 40, a material unloading platform 41 and a screening conveyor belt 42 provided on the workbench 40; the material unloading platform 41 is provided on both sides of the screening conveyor belt 42, and the screening conveyor belt 42 is provided with multiple manual screening stations, and a material unloading platform 41 is provided on both sides of each manual screening station, and the material unloading platform 41 is provided with a material unloading pipe 43, and a collection box 44 is provided below the material unloading pipe 43;
[0029] The dust removal mechanism 3 includes a box body 30, a blower 31 and a bag dust collector 32; the lower side of the box body 30 is connected to the blower 31 through an air duct, the top of the box body 30 is connected to the bag dust collector 32, and a first air guide plate 33 is provided on the top side of the box body 30.
[0030] Based on the above-mentioned structural setting, in the process of scrap aluminum falling from the feeding conveying mechanism 2 to the manual screening mechanism 4, the dust attached to the surface of the scrap aluminum will fall off from the surface of the scrap aluminum and drift into the box 30. Under the joint action of the blower 31 and the first air guide plate 33, the blower 31 can blow the dust generated when the scrap aluminum falls to the top of the box 30, and then be sucked in and processed by the bag dust collector 32 before being discharged, significantly reducing the dust content on the surface of the scrap aluminum, thereby improving the screening accuracy and reducing the amount of dust generated during the manual screening process, reducing the risk of workers being exposed to dust.
[0031] In this embodiment, a material blocking net 34 is provided at the connection between the blower 31 and the housing 30. The material blocking net 34 can prevent scrap aluminum from entering the air duct, thereby reducing the risk of air duct blockage and ensuring smooth operation of the blower 31.
[0032] In this embodiment, the interior of the housing 30 is further provided with a first inclined buffer plate 35 and a second inclined buffer plate 36. The first and second inclined buffer plates 35, 36 are staggered vertically, and a discharge port is formed between the first and second inclined buffer plates 35, 36. The first and second inclined buffer plates 35, 36 mitigate the impact force generated when scrap aluminum falls from a height, thereby reducing the direct impact of the scrap aluminum on the screening conveyor belt 42.
[0033] In this embodiment, a second air guide plate 37 is further disposed within the housing 30. The second air guide plate 37 is symmetrically arranged with the first inclined buffer plate 35 about a plane parallel to the horizontal plane and parallel to the second inclined buffer plate 36. One end of the second air guide plate 37 is connected to the inner wall of the housing 30, and the other end is connected to one end of the first inclined buffer plate 35. An air guide channel 38 is formed between the second air guide plate 37 and the second inclined buffer plate 36. The blower 31 blows air toward the air guide channel 38. This structural design allows the air blown by the blower 31 to enter the predetermined air guide channel 38, remove dust generated during the falling of the scrap aluminum, and finally enter the bag dust collector 32. The air blown through the air guide channel 38 also substantially prevents dust from entering the manual screening mechanism 4.
[0034] In this embodiment, the second inclined buffer plate 36 is provided with a vibration motor 39. The vibration motor 39 vibrates the second inclined buffer plate 36 to assist in unloading, thereby accelerating the unloading operation of the scrap aluminum.
[0035] In this embodiment, the first inclined baffle plate 35, the second inclined baffle plate 36, and the second air guide plate 37 are all angled at 30 degrees with the horizontal direction. This rational design of the angles allows the scrap aluminum to slide more stably along the first and second inclined baffle plates 35, 36, reducing lateral dispersion and accumulation of the scrap aluminum during the sliding process and improving the continuity and stability of the scrap aluminum's movement.
[0036] In this embodiment, the manual screening stations include a preliminary inspection station 45, an impurity removal station 46, a fine sorting station 47, a quality inspection station 48 and a review station 49 which are arranged in sequence.
[0037] In this embodiment, the discharge pipe 43 is Y-shaped and is provided with a first feed port 431, a second feed port 432, and a discharge port 433. The first feed port 431 is provided on the discharge platform 41 on one side of the screening conveyor belt 42, the second feed port 432 is provided on the discharge platform 41 on the other side of the screening conveyor belt 42, and the discharge port 433 is provided above the collection box 44. When workers are screening at a workstation on both sides of the screening conveyor belt 42, workers on both sides can feed the screened waste into the discharge pipe 43, achieving parallel operations, speeding up the waste processing, and making the entire production line more streamlined.
[0038] In summary, the scrap aluminum screening production line can solve the problem in the existing technology that scrap aluminum after automatic sorting directly enters the manual screening stage without undergoing further dust removal treatment, and the raised dust increases the difficulty of screening and causes impact on the human body.
[0039] In the absence of conflict, the above embodiments and features therein may be combined with each other.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
