Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically an aluminum ash screening machine. Background Technology

[0002] Aluminum ash is a solid waste generated during the production of aluminum molten ingots or aluminum industrial products. It is divided into primary aluminum ash (white ash) and secondary aluminum ash (black ash). It is mainly composed of aluminum oxide and contains metallic aluminum and other valuable components, but may also contain reactive and chemically toxic substances. Therefore, it is classified as hazardous waste. In order to improve resource utilization and reduce treatment costs, aluminum ash of different particle sizes needs to be collected by screening to maximize resource utilization.

[0003] In the current aluminum ash recycling process, due to the influence of the processing environment, some iron filings and other impurities are mixed in with the aluminum ash. Therefore, it is necessary to separate the iron filings and impurities from the aluminum ash first, and then screen the separated aluminum ash. This results in poor screening efficiency and some aluminum ash is lost during the transfer of the separated aluminum ash, leading to high aluminum ash loss. In order to further improve the screening efficiency of aluminum ash, an aluminum ash screening machine is now provided, which can eliminate the drawbacks of the existing device.

Multiple limiting rings 5 ​​are equidistantly formed on the outer wall of the screening cylinder 4, and all limiting rings 5 ​​are rotatably connected to the support frame 6. A discharge plate 10 is fixedly connected to one side of the feed frame 3, extending into the interior of the screening cylinder 4. A first collection box 7 and a second collection box 9 are respectively installed inside the base 1. The first collection box 7 is located below the screening cylinder 4, and the second collection box 9 is located below the feed frame 3. The base 1 is connected to the first collection box 7 and the second collection box 9 at the following positions. Each of the feeding frame 3 and the second collection box 9 is provided with a sliding chute for moving the first collection box 7 and the second collection box 9. The feeding frame 3 is connected to the second collection box 9 and the discharge plate 10 respectively with a first discharge port and a second discharge port. The first discharge port and the second discharge port are connected to the inner cavity of the feeding frame 3. The outer wall of the screen cylinder 4 is provided with multiple sets of discharge holes at equal intervals. The multiple sets of discharge holes are located between multiple limit rings 5. The inner diameter of the multiple sets of discharge holes increases from high to low. The base 1 is provided with a guide groove 8 below the multiple sets of discharge holes. The first collection box 7 is provided with a receiving groove at the port of the guide groove 8. The feeding frame 3 is provided with a screening mechanism for separating iron filings and impurities and driving the screen cylinder 4 to rotate.

[0030] The screening mechanism includes a rolling assembly mounted on the feed frame 3;

[0031] The rolling assembly includes: a roller 202 disposed inside the feed frame 3, and two connecting rings 2010 symmetrically fixedly connected to the outer wall of the roller 202. The two connecting rings 2010 respectively extend to the outside of both ends of the feed frame 3, and the connecting rings 2010 are rotatably connected to the feed frame 3.

[0032] The roller 202 is equipped with a suction component, which is used to attract iron filings and impurities and separate them from aluminum ash;

[0033] A scraper assembly is provided on the feed frame 3;

[0034] The support frame 6 is equipped with a drive assembly;

[0035] The material suction assembly includes: a support roller 207 disposed inside the drum 202; an electromagnet 208 fixedly connected to the outer wall of the support roller 207; two fixed shafts 206 symmetrically fixedly connected to the outer wall of the support roller 207; the two fixed shafts 206 respectively pass through to the outside of both ends of the drum 202; a connecting ring 2010 is rotatably sleeved on the outer wall of the fixed shafts 206; a support plate 2016 is fixedly connected to the ends of the two fixed shafts 206 that are far apart from each other; the support plate 2016 is located outside the feed frame 3; and the support plate 2016 is fixedly connected to the base 1.

[0036] In this embodiment, when in use, the electromagnet 208 is started by an external controller, and then the aluminum ash to be screened is poured into the inner cavity of the feed frame 3 through the feed inlet. At this time, the iron filings and impurities in the aluminum ash are attracted by the electromagnet 208 and adsorbed on the outer wall of the drum 202, while the aluminum ash slides along the outer wall of the drum 202.

[0037] Simultaneously, the screening mechanism can drive the drum 202 to rotate along the outer wall of the fixed shaft 206. At the same time, the aluminum ash moves to the inside of one side of the feed frame 3 under the rotation of the drum 202, and comes into contact with the inner wall of the discharge plate 10 through the second discharge port. At this time, the aluminum ash can move along the inner wall of the discharge plate 10 to the inner cavity of the screen cylinder 4 under the influence of gravity, and come into contact with the inner wall of the screen cylinder 4, and scrape off the iron filings and impurities adsorbed on the outer wall of the drum 202. This allows the iron filings and impurities to be separated from the outer wall of the drum 202. At the same time, under the influence of gravity, the iron filings and impurities fall into the inner cavity of the second collection box 9 through the first discharge port, thus allowing for convenient collection of the iron filings and impurities.

[0038] During this process, the screening mechanism drives the screening cylinder 4 to rotate. At the same time, the screening cylinder 4 rotates along the inner wall of the support frame 6 through the limiting ring 5. At this time, the aluminum ash in contact with the inner wall of the screening cylinder 4 moves to the lowest position of the screening cylinder 4 under the rotation of the screening cylinder 4. At this time, the aluminum ash can be graded and screened through multiple sets of discharge holes. At the same time, the screened aluminum ash can be discharged into the inner cavity of multiple receiving troughs through the guide chute 8, which can further improve the screening efficiency of aluminum ash.

[0039] In one embodiment, such as Figures 1-2As shown, the scraping assembly is a scraper 201 fixedly connected to the inner wall of the feed frame 3. The scraper 201 is located inside the feed frame 3 on the side away from the support frame 6. The scraper 201 is in contact with the outer wall of the roller 202. The scraper 201 can scrape off the iron filings and impurities adsorbed on the outer wall of the roller 202 and prevent aluminum dust from falling into the inner cavity of the second collection box 9.

[0040] In one embodiment, such as Figures 1-5 As shown, the drive assembly includes: a motor 2011 installed on the side of the support frame 6 away from the feed frame 3; a first bevel gear 2012 is fixedly connected to the output end of the motor 2011; a second bevel gear 2013 is meshed with the outer wall of the first bevel gear 2012; a connecting shaft 2014 is fixedly connected to one side of the second bevel gear 2013; the connecting shaft 2014 passes through the support frame 6 and is fixedly connected to the screen cylinder 4; and the connecting shaft 2014 is rotatably connected to the support frame 6.

[0041] A transmission assembly is provided on the second bevel gear 2013;

[0042] The transmission assembly includes: a third bevel gear 2015 meshing with the outer wall of the second bevel gear 2013; a transmission rod 205 fixedly connected to one end of the third bevel gear 2015 away from the second bevel gear 2013; a fixed sleeve plate fixedly connected to the support frame 6 rotatably sleeved on the outer wall of the transmission rod 205; a transmission gear 204 fixedly connected to one end of the transmission rod 205 away from the third bevel gear 2015; a synchronous belt 203 meshing with the outer wall of the transmission gear 204; a transmission gear ring 209 meshing with the inner side of the synchronous belt 203 away from the transmission gear 204; and the transmission gear ring 209 fixedly connected to the outer wall of a connecting rotating ring 2010. Through the mutual cooperation of the drive assembly and the transmission assembly, the screen cylinder 4 can be driven to rotate and screen aluminum ash while providing rotational power to the drum 202.

[0043] The above embodiment discloses an aluminum ash screening machine. It should be noted that: the electromagnet 208 is electrically connected to an external controller through a wire, and the support roller 207, another fixed shaft 206 and another support plate 2016 are all provided with holes and slots for the wires to pass through.

[0044] When in use, the electromagnet 208 is started by an external controller, and then the aluminum ash to be screened is poured into the inner cavity of the feed frame 3 through the feed inlet. At this time, the iron filings and impurities in the aluminum ash are attracted by the electromagnet 208 and adsorbed on the outer wall of the drum 202, while the aluminum ash slides along the outer wall of the drum 202.

[0045] Simultaneously, the motor 2011 is started to drive the first bevel gear 2012 to rotate. At this time, the second bevel gear 2013, driven by the meshing of the first bevel gear 2012, drives the third bevel gear 2015 to rotate. At the same time, the transmission gear 204, driven by the transmission rod 205 and the third bevel gear 2015, drives the transmission gear ring 209 to rotate via the synchronous belt 203. At this time, the drum 202, driven by the transmission gear ring 209, rotates along the outer wall of the fixed shaft 206 through a connecting ring 2010. Meanwhile, the aluminum ash moves to the inside of one side of the feed frame 3 under the rotation of the drum 202 and contacts the inner wall of the discharge plate 10 through the second discharge port. At this time, the aluminum ash can move along the inner wall of the discharge plate 10 to the inner cavity of the screen cylinder 4 under the influence of gravity and contact the inner wall of the screen cylinder 4.

[0046] When the iron filings and impurities adsorbed on the outer wall of the drum 202 come into contact with the outer wall of the scraper 201 under the action of the drum 202, the scraper 201 can separate the iron filings and impurities from the outer wall of the drum 202. At the same time, under the influence of gravity, the iron filings and impurities fall into the inner cavity of the second collection box 9 through the first discharge port, so as to collect the iron filings and impurities conveniently.

[0047] During this process, the screening cylinder 4, driven by the second bevel gear 2013 through the connecting shaft 2014, rotates along the inner wall of the support frame 6 through the limiting ring 5. At this time, the aluminum ash in contact with the inner wall of the screening cylinder 4 moves to the lowest position of the screening cylinder 4 under the rotation of the screening cylinder 4. At this time, the aluminum ash can be graded and screened through multiple sets of discharge holes. At the same time, the screened aluminum ash can be discharged into the inner cavity of multiple receiving troughs through the guide chute 8, thereby further improving the screening efficiency of aluminum ash.

[0048] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
