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.
[0028] The utility model provides a waste aluminum recycling and sorting device, such as Figures 1 to 3As shown, it includes a loading hopper 1, a loading conveying mechanism 2, a sorting mechanism 3, a discharging conveying mechanism 4 and a discharging box 5; the scrap aluminum passes through the loading conveying mechanism 2, the sorting mechanism 3, the discharging conveying mechanism 4 in sequence from the loading hopper 1, and finally falls into the discharging box 5; the sorting mechanism 3 includes a casing 31 and a sorting drum 32; the sorting drum 32 is rotatably connected to the casing 31; the sorting drum 32 is provided with a dust screening section 321, a primary material separation section 322 and a secondary material separation section 323; the casing 31 is provided with a final material discharge port 311, and the scrap aluminum passes through the loading conveying mechanism 2, the sorting mechanism 3, the discharging conveying mechanism 4 in sequence ... After passing through the dust screening section 321, the primary material distribution section 322, and the secondary material distribution section 323, the dust falls into the final discharge port 311. A hair dryer 33 is provided at one end of the casing 31 close to the final discharge port 311; the dust screening section 321 is provided with dust screening holes, and a dust collecting port 312 is provided at the bottom of the casing 31 and the dust collecting port 312 is located below the dust screening section 321. The dust collecting port 312 is provided with a dust collecting box 324. The upper part of the dust screening section 321 is connected to the suction fan 34 through the suction hood, and the air outlet of the suction fan 34 is connected to the dust removal device 35.
[0029] The sorting drum 32 can be a sorting drum with rotational power or a sorting drum with vibration power. Since the sorting drum is a prior art, the type of sorting drum to be used and the structure of how to provide power are not described in detail in this application.
[0030] Based on the above-mentioned structural setting, the scrap aluminum is transported to the sorting mechanism 3 through the feeding and conveying mechanism 2, and then passes through the dust screening section 321, the primary material separation section 322, the secondary material separation section 323 in sequence, and finally falls into the final discharge port 311. During this process, the dust falls into the dust collecting port 312 through the dust screening holes of the dust screening section 321, and finally falls into the dust collecting box 324. The dust floating inside the sorting cylinder 32 is blown to the dust screening section 321 by the blower 33, and then sucked into the dust removal device 35 by the suction fan 34, effectively preventing the dust from being discharged from the final discharge port 311 together with the scrap aluminum, thereby improving the purity of the final scrap aluminum.
[0031] In this embodiment, the dust removal device 35 includes a cyclone dust collector 351 and an exhaust fan 352. The cyclone dust collector 351 is provided with an air inlet 3511 and an air outlet 3512. The air inlet 3511 is connected to the suction fan 34 via an air inlet pipe 3513, and the air outlet 3512 is connected to the exhaust fan 352 via an exhaust pipe 3514. The cyclone dust collector 351 is provided with an inclined guide plate 3515, and the inclined guide plate 3515 is located at the air inlet 3511. The inclined guide plate 3515 at the air inlet 3511 guides the airflow to rotate in a predetermined direction, increases the rotation speed and stability of the airflow, thereby enhancing the centrifugal force and improving the dust removal effect.
[0032] In this embodiment, the inclination angle of the connecting section between the air inlet duct 3513 and the air inlet 3511, as well as the inclination angle of the inclined guide plate 3515, are both 5° to 10°. This structural design ensures that the airflow rotates while also rotating downward, helping to ensure that dust particles are absolutely refracted downward when they rebound, thereby reducing the formation of a dust ring at the top.
[0033] In this embodiment, the inner diameter of the dust screening section 321 is smaller than that of the primary separation section 322, and the inner diameter of the primary separation section 322 is smaller than that of the secondary separation section 323. This structural design helps smaller scrap aluminum to disperse more quickly when entering the primary and secondary separation sections 322 and 323, reducing accumulation and clogging of scrap aluminum during the separation process, helping to maintain unobstructed flow within the separation drum 32 and improving separation efficiency.
[0034] In this embodiment, guide ribs 325 are provided between the dust screening section 321 and the primary sorting section 322, and between the primary sorting section 322 and the secondary sorting section 323. The guide ribs 325 can effectively guide the scrap aluminum from the dust screening section 321 into the primary sorting section and from the primary sorting section into the secondary sorting section, ensuring the orderly transfer of the scrap aluminum during the sorting process. At the same time, they can reduce the drop of the scrap aluminum during the sorting process, thereby reducing the risk of impact and damage to the scrap aluminum during transfer.
[0035] In this embodiment, both the primary sorting section 322 and the secondary sorting section 323 are provided with sorting holes, the diameter of the sorting hole in the primary sorting section 322 being smaller than that in the secondary sorting section 323. A primary discharge port 313 and a secondary discharge port 314 are provided at the bottom of the housing 31, and the primary discharge port 313 and the secondary discharge port 314 are located below the primary sorting section 322 and the secondary sorting section 323, respectively. A primary collection bin 326 and a secondary collection bin 327 are provided at the primary discharge port 313 and the secondary discharge port 314, respectively. During the sorting process, primary scrap aluminum flows from the sorting holes in the primary sorting section 322 through the primary discharge port 313 and finally into the primary collection bin 326. Secondary scrap aluminum flows from the sorting holes in the secondary sorting section 323 through the secondary discharge port 314 and finally into the secondary collection bin 327.
[0036] In this embodiment, the unloading and conveying mechanism 4 includes a conveyor 41, a guide ramp 42, and a discharge ramp 43. One end of the conveyor 41 is connected to the final unloading port 311, and the other end is connected to the guide ramp 42. One end of the discharge ramp 43 is connected to the guide ramp 42, and the other end is connected to the discharge bin 5. The final scrap aluminum falls from the secondary sorting section 323 into the final unloading port 311. After being transported by the conveyor 41 to the guide ramp 42, the final scrap aluminum slides onto the discharge ramp 43 and finally falls into the discharge bin 5.
[0037] In this embodiment, a baffle plate 44 is provided at the junction of the discharge ramp 43 and the guide ramp 42. The baffle plate 44 effectively prevents the final scrap aluminum from deviating or falling to the ground during the process of sliding from the guide ramp 42 to the discharge ramp 43, thereby ensuring that the final scrap aluminum can be stably transported to the designated location.
[0038] In this embodiment, a feeding box 6 is provided between the feeding and conveying mechanism 2 and the sorting mechanism 3. The bottom of the feeding box 6 is an inclined surface, which can ensure that the scrap aluminum can slide to the sorting mechanism 3; the feeding box 6 is also provided with a vibration motor 61, which can ensure that the feeding box 6 vibrates with a stable frequency and amplitude, thereby realizing continuous and stable transportation of scrap aluminum, which helps to reduce the accumulation and blockage of scrap aluminum during the transportation process.
[0039] In summary, this type of scrap aluminum recycling and sorting equipment can solve the problem in the prior art that the scrap aluminum recycling and sorting equipment cannot effectively capture and process the dust generated during operation, resulting in the dust being discharged together with the scrap aluminum.
[0040] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.
[0041] 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.
