Description

Technical Field

[0001] This utility model belongs to the field of aluminum ash wind screening technology, specifically a wind screening device for aluminum ash purification. Background Technology

[0002] Aluminum ash is the slag and skimmed residue that floats on the surface of molten aluminum during the metallurgical processes of electrolytic aluminum, cast aluminum, and recycled aluminum. It also includes the residue left after subsequent processes such as ash frying and ball milling. Aluminum ash contains a large amount of metallic aluminum and aluminum compounds, and has high industrial recycling and reuse value. However, it also contains harmful ions and heavy metal elements, and improper handling can lead to environmental pollution problems.

[0003] Existing aluminum ash air screening devices mostly adopt a planar filter structure and are used in conjunction with a vibration module for the initial screening of aluminum ash. However, in order to improve the efficiency of the initial screening, the filter structure is generally large in area. However, when the aluminum ash has passed through the initial screening and the device starts air screening, the aluminum ash falls in a more dispersed manner due to the large area of ​​the filter, which is not conducive to air screening and affects the screening effect.

[0004] Therefore, this utility model provides a wind-powered screening device for purifying aluminum ash. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 6 As shown, an embodiment of the present invention provides a wind-powered screening device for purifying aluminum ash, comprising a housing 1, a fixed plate 11 fixedly connected to the side wall of the housing 1; a motor 12 fixedly connected to the side wall of the fixed plate 11, and a drive gear 13 fixedly connected to the output end of the motor 12; a planetary gear 14 meshing with the side wall of the drive gear 13; a rotating drum 15 meshing with the side wall of the planetary gear 14; a flange 16 fixedly connected to the side wall of the rotating drum 15; a connecting block 17 provided on the side wall of the flange 16, and bolts provided between the flange 16 and the connecting block 17; a screen cylinder 18 fixedly connected to the side wall of the connecting block 17; a feed inlet 19 fixedly connected to the side wall of the housing 1, and the feed inlet 19 being positioned corresponding to the screen cylinder 18; during operation, the operator can use the feed inlet 19 to feed the aluminum ash to be wind-screened into the screen cylinder 18, and simultaneously, the operator can rotate the screen cylinder 18 by driving the motor 12. During the process, whenever the screen cylinder is fixed to the side of the fixed plate 11... When the motor 12 on the wall is driven, the drive gear 13 fixed to the output end of the motor 12 will rotate. At this time, since the drive gear 13 is meshed with the planetary gear 14 and the planetary gear 14 is meshed with the rotating drum 15, the rotating drum 15 will rotate along with the output of the motor 12. The flange 16, the connecting block 17, and the screen cylinder 18 connected to the connecting block 17 will rotate synchronously. The operator can disconnect the connection between the connecting block 17 and the screen cylinder 18 by removing the bolts. The housing 1 plays a role in overall fixation. Through the above structure, the rotatable screen cylinder 18 is set to split aluminum ash, thereby filtering out larger impurities. The motor 12 provides power to the screen cylinder 18, and the drive gear 13, planetary gear 14, and rotating drum 15 transmit power, enhancing the output torque of the motor 12. This helps to avoid the problem of the screen cylinder 18 not rotating smoothly when it is too heavy, and helps to enhance the stability of the device.

[0027] like Figure 1 and Figure 2As shown, a fan 2 is fixedly connected to the side wall of the casing 1, and the two fans 2 are arranged correspondingly; an air duct 21 is fixedly connected to the side wall of the casing 1; a material distribution head 22 is provided at the end of the screen cylinder 18; a partition 23 is fixedly connected inside the casing 1, and the partition 23 is positioned corresponding to the material distribution head 22; a discharge plate 24 is fixedly connected inside the casing 1, and the discharge plate 24 is positioned corresponding to the partition 23; during operation, larger impurities can be discharged from the screen cylinder 18 through the material distribution head 22. During the process, since the screen cylinder 18 rotates continuously under the action of the motor 12, and the screen cylinder 18 is inclined, impurities that cannot be discharged through the holes on the surface of the screen cylinder 18 will gradually reach the bottom of the screen cylinder 18 under their own gravity, and will be discharged from the material distribution head 22 at the bottom of the screen cylinder 18. The impurities that slide out of the screen cylinder 18 from the distributor head 22 will fall to the top of the discharge plate 24 and slide out of the device from the discharge plate 24. At the same time, the aluminum falling from the screen cylinder 18 will be affected by the wind generated by the fan 2, and the light impurities in the aluminum ash will be blown out and enter the air duct 21 from the casing 1. The partition 23 serves to divide the internal space of the casing 1. Through the above structure, the fan 2 and the air duct 21 are set to blow out the light impurities in the aluminum ash, the distributor head 22 is set to discharge the large particles of impurities from the screen cylinder 18 to avoid them accumulating in the screen cylinder 18 and causing blockage, and the partition 23 is set to divide the internal space of the casing 1 to prevent the aluminum ash from leaking under the action of the wind, thus improving the practicality of the device.

[0028] like Figures 3 to 5 As shown, a limiting rod 3 is provided inside the screen cylinder 18; a limiting ring 31 is provided inside the feed inlet 19; a fixing plate 32 is fixedly connected between the feed inlet 19 and the limiting ring 31, and multiple fixing plates 32 are arranged in a circumferential array; during operation, the limiting rod 3 fixed inside the screen cylinder 18 contacts the inner wall of the limiting ring 31. When the screen cylinder 18 rotates under the action of the motor 12 and when it is stationary, the limiting ring 31 can restrict the posture of the limiting rod 3 by contact, thereby restricting the posture of the screen cylinder 18. The fixing plate 32 serves to fix the limiting ring 31. Through the above structure, the limiting rod 3 and the limiting ring 31 restrict the posture of the screen cylinder 18, thereby preventing the screen cylinder 18 from tilting under the action of aluminum ash and its own weight, which is beneficial to improving the stability of the device and extending the service life of the device.

[0029] like Figure 3As shown, a meshing block 4 is fixedly connected to the side wall of the flange 16; a meshing groove 41 is provided on the side wall of the connecting block 17, and the meshing groove 41 is set to correspond to the size and position of the meshing block 4; during operation, after the operator connects the flange 16 and the connecting block 17 with bolts, the meshing block 4 fixed to the side wall of the flange 16 is located inside the meshing groove 41 opened on the surface of the connecting block 17, and the two can transmit the stress to the connecting block 17 through contact; through the above structure, the meshing block 4 and the meshing groove 41 are set to transmit the power of the motor 12, thereby preventing the flange 16 and the connecting block 17 from loosening during stress transmission, which is beneficial to optimizing the transmission effect of the device and reducing the maintenance requirements of the device.

[0030] like Figure 2 As shown, a collection box 5 is provided at the bottom of the casing 1; a handle 51 is fixed to the side wall of the collection box 5; during operation, the aluminum ash that falls out of the screen cylinder 18 and is purified by the fan 2 will fall into the collection box 5 under its own gravity. The operator can use the handle 51 to pull out the collection box 5 and take out the purified aluminum ash. Through the above structure, the collection box 5 is set to hold the purified aluminum ash, and the handle 51 is set to facilitate the pulling out of the collection box 5, which is conducive to improving the purification efficiency of aluminum ash and reducing the difficulty of aluminum ash discharge.

[0031] like Figure 4 As shown, a feed pipe 6 is provided on the side wall of the feed inlet 19, and a bolt is provided between the feed inlet 19 and the feed pipe 6. During operation, the operator can install the feed pipe 6 on the side wall of the feed inlet 19 using the bolt. After installation, the end of the feed pipe 6 will enter the inside of the screen cylinder 18. Whenever aluminum ash enters the inside of the feed inlet 19, the aluminum ash can enter the screen cylinder 18 under the guidance of the feed pipe 6. Through the above structure, the feed pipe 6 is set to guide the aluminum ash into the screen cylinder 18, thereby preventing the aluminum ash from leaking from the gap between the feed inlet 19 and the screen cylinder 18, improving the sealing performance of the device, and helping to maintain a clean working environment.

[0032] like Figure 1 As shown, the surfaces of the casing 1 and the air duct 21 are coated with an anti-rust coating. During operation, the anti-rust coating can increase the surface oxidation resistance of the casing 1 and the air duct 21. Through the above, the anti-rust coating applied to the casing 1 and the air duct 21 enhances the oxidation resistance of the device, which is beneficial to extending the component life of the device and reducing maintenance requirements.

[0033] During operation, workers can feed the aluminum ash to be air-screened into the screen cylinder 18 through the feed inlet 19. Simultaneously, workers can rotate the screen cylinder 18 by driving the motor 12. During this process, whenever the motor 12, fixed to the side wall of the fixed plate 11, is driven, the drive gear 13, fixed to the output end of the motor 12, will rotate. At this time, since the drive gear 13 meshes with the planetary gear 14, and the planetary gear 14 meshes with the rotating drum 15, the rotating drum 15 will rotate along with the output of the motor 12. The flange 16, the connecting block 17, and the screen cylinder 18 connected to the connecting block 17 will rotate synchronously. Workers can disconnect the connection between the connecting block 17 and the screen cylinder 18 by removing the bolts. The machine housing 1 serves to fix the whole structure. Larger impurities can be discharged from the screen cylinder 18 through the distributing head 22. During the process, since the screen cylinder 18 rotates continuously under the action of the motor 12 and the screen cylinder 18 is inclined, impurities that cannot be discharged through the holes on the surface of the screen cylinder 18 will gradually reach the bottom of the screen cylinder 18 under their own gravity and slide out from the distributing head 22 at the bottom of the screen cylinder 18. Subsequently, the impurities that slide out of the screen cylinder 18 from the distributing head 22 will fall to the top of the discharge plate 24 and slide out of the device from the discharge plate 24. At the same time, the aluminum falling from the screen cylinder 18 will be subjected to The airflow generated by the fan 2 blows out light impurities in the aluminum ash, which then enter the duct 21 through the casing 1. The partition 23 divides the internal space of the casing 1. The limiting rod 3, fixed inside the screen cylinder 18, contacts the inner wall of the limiting ring 31. When the screen cylinder 18 rotates under the action of the motor 12, and when it is stationary, the limiting ring 31 restricts the posture of the limiting rod 3 through contact, thereby limiting the posture of the screen cylinder 18. The fixing plate 32 fixes the limiting ring 31. After the operator connects the flange 16 and the connecting block 17 with bolts, the engagement block 4, fixed to the side wall of the flange 16... The meshing groove 41 opened on the surface of the connecting block 17 allows the two to transmit the stress to the connecting block 17 through contact. The aluminum ash that falls out of the screen cylinder 18 and is purified by the blower 2 will fall into the collection box 5 under its own gravity. The operator can use the handle 51 to pull out the collection box 5 and take out the purified aluminum ash. The operator can use bolts to install the feed pipe 6 on the side wall of the feed port 19. After installation, the end of the feed pipe 6 will enter the screen cylinder 18. Whenever aluminum ash enters the feed port 19, it can enter the screen cylinder 18 under the guidance of the feed pipe 6. The anti-rust coating can increase the surface oxidation resistance of the casing 1 and the air duct 21.
