Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0022] like Figure 1-4 As shown, the present application provides an aluminum ash drum screening mechanism, which is provided with a frame 1, a shell 2 is connected to the frame 1, a drum screen 3 is arranged in the shell 2, the drum screen 3 and the shell 2 are both inclined, a slide 4 is arranged on the drum screen 3, a pulley 5 is connected to the frame 1, the pulley 5 cooperates with the slide 4, a plurality of filtering holes 6 are arranged on the side wall of the drum screen 3, the apertures of the plurality of filtering holes 6 gradually increase from the higher end of the drum screen 3 to the lower end, an electromagnet 7 is connected to the inner wall of the drum screen 3, a guide block 8 is axially arranged at the axis position of the inner axis of the drum screen 3, the top of the guide block 8 is concave, and a plurality of ventilation holes 9 are arranged on the side wall of the concave part of the top of the guide block 8, a connecting cloth 10 is connected to the corresponding position of the top of the guide block 8 and the concave part, one side of the guide block 8 is connected to one end of a connecting pipe 11, and the other end of the connecting pipe 11 is connected to an air pump, a first gear 12 is arranged on the outer edge of the lower end of the drum screen 3, and the drum screen 3 is cooperated with a power mechanism through the first gear 12.
[0023] In the technical solution adopted in this embodiment, by setting a drum screen 3 and setting filtering holes 6 of different sizes on the surface of the drum screen 3, the graded screening of aluminum ash can be achieved. Specifically, the drum screen 3 is driven to rotate by the cooperation of the power mechanism and the first gear 12, so as to achieve the screening of aluminum ash. By setting the cooperation of the chute 4 and the pulley 5, the rotation of the drum screen 3 can be made more stable, thereby ensuring the stable screening work.
[0024] By setting the electromagnet 7, the iron-containing impurities mixed in the aluminum ash can be adsorbed, thereby ensuring the purity of the aluminum ash collected after screening. It should be noted that in this embodiment, the number of the electromagnets 7 can be set according to the amount of iron-containing impurities in the aluminum ash to ensure the adsorption effect of the iron-containing impurities;
[0025] The guide block 8 is provided to guide the iron-containing impurities, which is convenient for collecting the iron-containing impurities. Specifically, after the screening of the aluminum ash is completed, the electromagnet 7 is rotated to the position corresponding to the top of the guide block 8 in sequence, and then the power is turned off. At this time, the iron-containing impurities fall to the concave part of the top of the guide block 8, and move along the inclined guide block 8 under the action of gravity, so as to realize the collection of the iron-containing impurities. It should be noted that in this embodiment, the guide block 8 is connected to the housing 2;
[0026] The connecting cloth 10 is provided to prevent the aluminum ash from falling into the concave part of the guide block 8 during the screening process. Specifically, the air pump pumps air into the guide block 8 through the connecting pipe 11, and the air props up the connecting cloth 10 through a plurality of air vents 9. At this time, the connecting cloth 10 protrudes outward, thereby preventing the aluminum ash from falling into the concave part at the top of the guide block 8. When the iron-containing impurities are recovered, the air pump sucks air into the guide block 8 through the connecting pipe 11. At this time, the connecting cloth 10 fits with the concave part at the top of the guide block 8. As the electromagnets 7 are powered off in turn, the iron-containing impurities fall onto the surface of the connecting cloth 10, move along the inclined guide block 8, and finally complete the collection work.
[0027] Furthermore, in the present embodiment, the power mechanism comprises a motor 13 , an output end of the motor 13 is connected to a second gear 14 , and the second gear 14 is matched with the first gear 12 via a chain 15 .
[0028] In the technical solution adopted in this embodiment, a motor 13 is provided to provide power for the rotation of the drum screen 3. The motor 13 drives the second gear 14 to rotate, thereby driving the chain 15 to move, and then driving the first gear 12 and the drum screen 3 to rotate. The rotating drum screen 3 can make the aluminum ash move fully, thereby ensuring a good screening effect.
[0029] Furthermore, in the present embodiment, the bottom of the outer shell 2 is provided with a first discharge port 16, a second discharge port 17 and a third discharge port 18 in sequence from the higher end to the lower end, and a first collecting box, a second collecting box and a third collecting box are provided at positions corresponding to the first discharge port 16, the second discharge port 17 and the third discharge port 18 below the outer shell 2.
[0030] In the technical solution adopted in this embodiment, a first discharge port 16, a second discharge port 17 and a third discharge port 18 are provided to realize the collection of aluminum ashes of different sizes. By providing a first collection box, a second collection box and a third collection box, the collection of aluminum ashes of different sizes is further facilitated.
[0031] Furthermore, in this embodiment, a feed port is provided at a position corresponding to the higher end of the outer shell 2 and the drum screen 3 , and a fourth discharge port is provided at a position corresponding to the lower end of the outer shell 2 and the drum screen 3 .
[0032] In the technical solution adopted in this embodiment, a feed port is provided to facilitate the feeding of aluminum ash into the drum screen 3, and a fourth discharge port is provided to facilitate the discharge of larger pieces of aluminum ash from the drum screen 3, thereby facilitating the collection of larger pieces of aluminum ash.
[0033] Furthermore, in this embodiment, the first guide plate 19 is connected to the position of the housing 2 corresponding to the fourth discharge port.
[0034] In the technical solution adopted in this embodiment, a first guide plate 19 is provided to guide larger pieces of aluminum ash, thereby facilitating the collection of the large pieces of aluminum ash.
[0035] Furthermore, in the present embodiment, a fifth discharge port is provided at a position corresponding to the lower end of the outer shell 2 and the guide block 8, and the outer shell 2 is connected to a second guide plate 20 at the fifth discharge port.
[0036] In the technical solution adopted in this embodiment, a second guide plate 20 is provided to guide the iron-containing impurities, thereby facilitating the collection of the iron-containing impurities.
[0037] Furthermore, in this embodiment, an anti-collision layer is connected to the surface of the connecting cloth 10 .
[0038] In the technical solution adopted in this embodiment, the anti-collision layer is provided to prevent the connection cloth 10 from being damaged due to long-term impact by aluminum ash and iron-containing impurities, thereby ensuring the safety of the screening process and increasing the service life of the screening mechanism.
[0039] The working principle of the utility model is as follows: first, the motor 13 is started to drive the drum screen 3 to rotate, the air pump is inflated to make the connecting cloth 10 bulge upward, and the electromagnet 7 is energized to make it magnetic, and then the raw material is put into the drum screen 3 in the shell 2 through the feed port, and the iron-containing impurities in the raw material will be sucked when they come into contact with the electromagnet 7, and the aluminum ash will rotate with the drum screen 3, and the filter holes 6 of different sizes on the surface of the drum screen 3 will screen the aluminum ash of different sizes, and the aluminum ash of different sizes will be discharged from the first discharge port 16, the second discharge port 17 or the third discharge port 18 after passing through the filter holes 6, and the larger pieces that cannot pass through the filter holes 6 will be discharged. Aluminum ash is discharged from the fourth discharge port. The above process can separate the iron-containing impurities in the aluminum ash raw material, and grade and collect aluminum ash of different sizes. After the aluminum ash is screened, the air pump sucks air to make the connecting cloth 10 fit downward with the top concave part of the guide block 8, and the rotating drum screen 3 rotates different electromagnets 7 to the positions corresponding to the top concave part of the guide block 8 in turn, and then the power is turned off to make the electromagnet 7 lose its magnetism, and the iron-containing impurities adsorbed on its surface will fall to the top concave part of the guide block 8, and move along the inclined guide block 8, and finally be discharged from the shell from the fifth discharge port, so as to realize the collection of iron-containing impurities.
[0040] The utility model can realize adsorption of iron-containing impurities in aluminum ash raw materials by setting the electromagnet 7, and realize separation of aluminum ash and iron-containing impurities in the aluminum ash raw materials; arranging filter holes 6 of different sizes on the surface of the drum screen 3 can realize graded screening of aluminum ash; by setting the guide block 8 and connecting the connecting cloth 10, when the aluminum ash is screened, the connecting cloth 10 protrudes outward to prevent the aluminum ash from entering the concave part of the guide block 8, and when the iron-containing impurities are collected, the connecting cloth 10 fits with the concave part of the top of the guide block 8, and can guide the iron-containing impurities, so as to facilitate the collection of the iron-containing impurities.
